Description

A rolling compaction device for construction of drill slag as roadbed filler

Technical Field

The invention relates to the field of road construction, in particular to a rolling and compacting device for construction of drill slag as roadbed filler.

Background Art

With the development of industrial technology, modern road construction technology has become more and more perfect. One of the most important steps in roadbed construction is to compact the ground. It is difficult to maintain the flatness of the ground during the compaction process. If there are depressions or bulges on the roadbed, it will affect the subsequent road paving operations.

Just like the roadbed structural layer thickness detection device published by patent No. 202110523868.X, it belongs to the technical field of road construction detection, and solves the problem that the existing thickness measurement method will damage the road surface many times and cause bad consequences. The present invention includes a frame, and a support plate is connected to the frame, and a group of ball screws and slide rails are installed on the support plate. The ball screw drives a traveling trolley to move under the drive of the driving device, and the thickness change of the road surface is reflected to the measuring device through the movement of the traveling trolley. The present invention can follow the roller to quickly detect the thickness of the road surface that has just been paved and rolled, which is convenient for the supervisor to check the rolling condition of the road, and adopts a staged thickness data collection method, which can accurately calculate the thickness and thickness change of each position of the corresponding road section, and can perform thickness detection on the road surface with different inclination angles of the roadbed below the structural layer, with a wide range of adaptability and strong practicality.

The device still has defects when in use. First, it is difficult to adjust the pressure of the device on the ground. Different road construction standards require different pressures, which requires adding or reducing gravity blocks on the compacting device. This operation is more troublesome. Second, there will be granular stones in the roadbed during the compaction process. After these stones are compacted, some of them will protrude from the ground, which will affect subsequent processing operations. Third, there will still be depressions and protrusions after the road surface is compacted. These depressions and protrusions are difficult to observe with the naked eye, so it is impossible to fill and level the roadbed. The tiny depressions and protrusions on the roadbed will cause trouble for subsequent road paving, which will cause slight unevenness on the road.

Summary of the invention

The purpose of the present invention is to address the deficiencies in the prior art and to provide a rolling compaction device for use of drill slag as roadbed filler in construction. When the device is in use, the base plate is connected to a tractor vehicle, and at this time, four groups of pressing cylinders will contact the ground at the same time. At this time, the rotating plug rod and the surrounding plate have a certain torsion, so that the pressure of the four groups of pressing cylinders on the ground will be very close. When it is necessary to adjust the pressure on the ground, the balance plate is turned upright and horizontally, and the benchmark is used to pass the balance plate into the locking hole, so that only two groups of pressing cylinders are left to contact the ground. The pressure of the pressing cylinders on the ground will be doubled, thereby achieving the effect of conveniently adjusting the compaction pressure.

The pressure of the pressing cylinders on the ground will increase by two times, achieving the effect of conveniently adjusting the compaction pressure.

Secondly, the torsion motor drives the swing arm to twist so that the interactive gear and the rack come into contact with each other. At this time, the lifting motor will drive the rack to rise through the interactive gear, and then the compression column will be lifted to the specified height. When the rack is released, the compression column will impact down with its own weight, and the impact plate and the crushing teeth will break the protruding stone particles on the ground. When the roadbed is rolled again, the road surface can be made smoother, or the stone is crushed into fine powder, and the fine powder will be compacted again and completely embedded in the roadbed.

Thirdly, the towing rod and the pallet box fall down with their own weight, which will not affect the total gravity of the device. When the pallet box passes across the ground, the raised parts will be scratched once, and the sunken parts will not be scratched. This will mark the ground. When the subsequent staff are filling the ground, the water pump will continue to extract water vertically and sprinkle it on the road surface to prevent a large amount of dust from flying up, making it easier for observers to see the construction site.

Referring to Figures 1 to 7, a rolling compaction device for construction of drill slag as roadbed filler includes a base plate 1, and four columns 2 are provided at the bottom end of the base plate 1. The four columns 2 form two front and rear groups, and the bottom ends of the columns 2 are provided with hinged blocks 201. The bottom end of the hinged block 201 is rotatably provided with a rotating plug rod 202, and the bottom end of the rotating plug rod 202 is provided with a surrounding plate 203. A balancing plate 204 is fixedly installed on the outer side of the surrounding plate 203. The front and rear ends of the balancing plate 204 are provided with shaft rods, and both ends of the shaft rods are provided with pressing cylinders 205. The shaft rods are connected to the driving assembly. The balancing plate 204 is also provided with a pressure regulating mechanism, and the pressure regulating mechanism includes a locking hole 209 on the column 2, and a locking hole 209 is inserted There is a benchmark 210, and a positioning pin hole that is docked with the benchmark 210 is provided on the balance plate 204. A square sleeve 3 is provided in the middle of the base plate 1, and a crushing mechanism is provided in the middle of the square sleeve 3. A pulling plate 5 is also provided on the top of the base plate 1, and a support plate assembly is provided on the pulling plate 5. When it is necessary to adjust the pressure on the ground, the balance plate 204 is erected and turned horizontally, and the benchmark 210 is used to pass the balance plate 204 into the locking hole 209, so that only two groups of pressing tubes 205 are left to contact the ground. The pressure of the pressing tube 205 on the ground will increase by two times, thereby achieving the effect of conveniently adjusting the compaction pressure. If the construction requires a relatively large compaction degree, two groups of pressing tubes 205 are used to press the ground. If a relatively small pressure is required, four groups of pressing tubes 205 are used to contact the ground.

As shown in FIG6 , the interior of the pressing cylinder 205 is provided with a plurality of annularly arranged sockets 212, lead columns are inserted into the interior of the sockets 212, a cover plate 211 is installed at the port of the sockets 212, and a plurality of lead columns are inserted into the sockets 212 in the pressing cylinder 205. The number of lead columns is adjusted according to the construction requirements, and the cover plate 211 is locked to the port of the socket 212 by bolts.

As shown in Figure 6, the outside of the lead column is wrapped with a layer of rubber pad, which compacts the gap between the lead column and the socket 212. The lead column locks the inner wall of the socket 212 to prevent the lead column from shaking too much, or replacing the lead column with a smaller diameter requires a rubber pad with a thicker thickness.

As shown in Figure 5, the driving assembly includes a propulsion motor 206 at the top of the balance plate 204, and a reduction pulley 207 is installed at the output end of the propulsion motor 206. A driven roller is arranged on the shaft, and the driven roller and the reduction pulley 207 are connected by a reduction belt 208. When the vehicle is not towed out, the propulsion motor 206 drives the reduction belt 208 through the reduction pulley 207, and the reduction belt 208 drives the driven roller to rotate, and then the pressing cylinder 205 will twist the propulsion device, and the traction vehicle will also affect the compaction degree of the roadbed.

As shown in Figure 4, the crushing mechanism includes a compression column 4 inserted into the square sleeve 3, and an adjusting column 402 is provided at the bottom end of the compression column 4. An impact plate 401 is provided at the bottom end of the adjusting column 402. The compression column 4 is connected to the lifting drive mechanism, which lifts the compression column 4 to a certain height, and then the compression column 4 is dropped down and falls with its own weight. The impact plate 401 will crush the protruding stone particles on the ground, and the crushed stones will all sink into the roadbed when they are compacted again, thereby achieving the effect of processing granular stones.

As shown in Figure 4, the lifting drive mechanism includes a torsion shaft seat 8 at the top of the base plate 1, and a swing arm 801 is rotatably installed on one side of the torsion shaft seat 8. The end of the swing arm 801 is installed on the output end of the torsion motor 802. A lifting motor 804 is arranged on the side wall of the other end of the swing arm 801, and an interactive gear 803 is installed at the output end of the lifting motor 804. A wire groove is arranged on one side of the compression column 4, and a rack 404 is installed in the wire groove. The interactive gear 803 and the rack 404 are meshed with each other. The torsion motor 802 drives the swing arm 801 to twist so that the interactive gear 803 and the rack 404 are in contact with each other. At this time, the lifting motor 802 will drive the rack 404 to rise through the interactive gear 803, and then the compression column 4 will be lifted to the specified height together. When the rack 404 is released, the compression column 4 will impact down with its own weight.

As shown in FIG4 , a plurality of rectangular array crushing teeth 403 are provided at the bottom end of the impact plate 401 , and the crushing teeth 403 are made of high-speed steel. The crushing teeth 403 increase the crushing property with stones. When any of the crushing teeth 403 is worn, the crushing teeth 403 is removed and replaced with new ones.

As shown in FIG4 , organic oil is applied between the compression column 4 and the square sleeve 3 . The oil between the compression column 4 and the square sleeve 3 will reduce friction and reduce the kinetic energy loss of the compression column 4 . If a greater crushing speed is required, the compression column 4 is lifted to a higher height.

As shown in Figure 7, the pallet assembly includes a pallet box 7, the bottom end of the pallet box 7 is provided with two arc chamfers 701, the inner side of the pallet box 7 is provided with a water pump 702 and a water tank 703, the bottom end of the pallet box 7 is provided with a plurality of leakage holes, the pallet box 7 is connected to the base plate 1 through a pulling assembly, when the pallet box 7 passes over the ground, the raised parts will be scratched once, and the sunken parts will not be scratched, which will mark the ground. When the subsequent staff are performing filling operations, the water pump 702 at this time continuously extracts water vertically and sprinkles it on the road surface to prevent a large amount of dust from flying up, making it easier for observers to see the construction site.

As shown in Figure 7, the pulling assembly includes a towing rod 6 on one side of the pallet box 7, a pulling plate 5 is provided at the top of the base plate 1, the pulling plate 5 is connected to the top surface of the base plate 1 through a pin, and a sleeve 501 is provided at the top of the pulling plate 5. The end of the towing rod 6 is rotatably connected to the sleeve 501. The towing rod 6 and the pallet box 7 fall down with their own weight and will not affect the total gravity of the device.

Working principle: when the pressure on the ground needs to be adjusted, turn the balance plate 204 upright and horizontally, and then let the benchmark 210 pass the balance plate 204 into the locking hole 209, so that only two groups of pressing tubes 205 are left to contact the ground. The pressure of the pressing tubes 205 on the ground will be increased by two times, realizing the effect of convenient adjustment of the compaction pressure. If the construction requirements require a larger compaction degree, let two groups of pressing tubes 205 press the ground. If a smaller pressure is required, let four groups of pressing tubes 205 contact the ground, and insert several lead columns into the sockets 212 in the pressing tubes 205. The number of lead columns is adjusted according to the construction requirements. 211 is locked to the port of the socket 212 by bolts, and the lead column locks the inner wall of the socket 212 to prevent the lead column from shaking too much, or replace the lead column with a smaller diameter, which requires a thicker rubber pad. When the vehicle is not towed out, the propulsion motor 206 drives the deceleration belt 208 through the deceleration wheel 207, and the deceleration belt 208 drives the driven roller to rotate, and then the pressing cylinder 205 will twist the propulsion device, and the tractor will also affect the compaction degree of the roadbed, lift the compression column 4 to a certain height, and then the compression column 4 is dropped down and falls with its own weight, and the impact plate 401 will smash the protrusions on the ground. The crushed stones will sink into the roadbed when compacted again, achieving the effect of processing granular stones. The torsion motor 802 drives the swing arm 801 to twist so that the interactive gear 803 and the rack 404 are in contact with each other. At this time, the lifting motor 802 drives the rack 404 to rise through the interactive gear 803, and then the compression column 4 will be lifted to the specified height together. When the rack 404 is loosened, the compression column 4 will impact down with its own weight, and the crushing teeth 403 increase the crushing property of the stones. When any of the crushing teeth 403 is worn, the crushing teeth 403 will be removed and replaced. The new oil between the compression column 4 and the square sleeve 3 will reduce the friction and the kinetic energy loss of the compression column 4. If a higher crushing speed is required, the compression column 4 will be lifted to a higher height. When the pallet box 7 passes over the ground, the raised areas will be scratched once, and the sunken areas will not be scratched. This will mark the ground. When subsequent staff are filling the ground, the water pump 702 will continue to extract water vertically and sprinkle it on the road surface to prevent a large amount of dust from flying up, making it easier for observers to see the construction site. The towing rod 6 and the pallet box 7 fall down with their own weight and will not affect the total gravity of the device.

The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
