A hooking and pulling device for replacing an eccentric cone of a railway turnout is shown in fig. 1 and comprises a handle 1, a supporting tube 2, a pulling-up assembly 3, a stripping assembly 4 and a pulling-assisting device 6. The upper end of the supporting tube 2 is fixedly connected with a handle 1, and the lower end is connected with a pulling-up assembly 3.
The function of pulling up the subassembly 3 is to draw out eccentric cone 9 from hole 81 in, and it includes two buckles 31 that the symmetry set up, and the one end of two buckles 31 is articulated, is provided with spring 32 between two buckles 31, and the lateral surface of buckle 31 is provided with the trip 33 that can block into eccentric cone 9 bottom recess 91. When in use, the handle 1 is held, and the supporting tube 2 with the buckle 31 at the bottom end is extended into the hole 81; after the buckle 31 clamps the eccentric cone 9, the eccentric cone 9 is pulled out.
As shown in fig. 2, the stripping assembly 4 is provided to facilitate removal of the extracted eccentric cone 9 from the hook and extractor device. Which includes a release lever 41 and a first brake cable 44. The first brake cable includes a first inner wire 46 and a first wire pipe 47, and referring to fig. 4, one end of the first inner wire 46 of the first brake cable 44 is connected to the taper shank 41, and the other end passes through the hollow of the support tube 2 and protrudes from a port at the bottom end of the support tube 2. The extending end of the first inner wire 46 is provided with a bifurcation 441, and the bifurcation 441 is respectively connected with the inner side surfaces of the two buckles 31. Referring to fig. 1 and 2, one end of a first spool 47 of the first brake cable 44 is connected to one end of the support tube 2 near the handle 1, and the other end is connected to the outer wall of the support tube 2, and the connection position is located where the first inner wire 46 is inserted into the support tube 2.
Referring to fig. 2 and 3, when the release lever 41 is pulled, the inner wire 46 of the bifurcated head 441 is pulled upward to drive the two buckles 31 to approach each other, the hook 33 slides out from the bottom groove 91 of the eccentric cone 9 (see fig. 5), and the eccentric cone 9 automatically falls off from the hook-and-pull device under the action of gravity.
Further, in order to improve the falling-off efficiency of the eccentric cone 9, referring to fig. 2 and 3, the stripping assembly 4 further includes a pushing sleeve 42, a return spring 43, and a second brake cable 45. As shown in fig. 3, the pushing sleeve 42 is sleeved on the outer surface of the supporting tube 2; the return spring 43 is arranged between the end of the support tube 2 close to the catch 31 and the pushing sleeve 42. Referring to fig. 2 and 3, one end of a second inner wire 48 of the second brake cable 45 is connected to the release lever 41, and the other end is connected to the end of the support tube 2 near the buckle 31; one end of a second spool 49 of the second brake cable 45 is connected with one end of the support tube 2 close to the handle 1, and the other end is connected with a port of the pushing sleeve 42 far away from the buckle. When the cone-releasing handle 41 is pulled, the second inner wire 48 of the second brake cable 45 is pulled upwards, so that the eccentric cone 9 approaches the pushing sleeve 42, and the eccentric cone 9 is separated from the hook and pull-out device under the action of the pushing sleeve 42.
The first brake cable 44 and the second brake cable 45 are both connected to the taper shank 41, the taper shank 41 is pulled, and when the two clamping blocks are retracted, the pushing sleeve 42 is pushed downwards, so that the eccentric taper 9 is separated, and the separation efficiency and the success rate are greatly improved. After the eccentric cone 9 is separated, the pushing sleeve 42 returns to the original position under the action of the return spring 43.
The handle 1 and the release lever 41 may be hinged or slidably connected so long as pulling of the brake cable is accomplished. The preferred structure can be as shown in fig. 1, the handle 1 is in a vertical ring shape, the cone removing handle 41 is also in a ring-shaped structure, the cone removing handle 41 is positioned in the ring-shaped handle, two ends of the cone removing handle 41 in the horizontal direction are in sliding connection with two vertical rods 11 of the ring-shaped handle, a wire tube 47 of a first brake wire 44 is connected with a bottom cross rod 12 of the ring-shaped handle, and a first inner wire 46 and a second inner wire 48 of the brake wire are connected with the bottom cross rod 12 of the ring-shaped cone removing handle. As shown in the figure, the cone removing handle 41 is fixedly connected with the support tube 2, and the bottom cross bar 12 of the handle 1 is slidably connected to the outer surface of the support tube 2. When the brake cable pulling device is used, the pulling of two brake cables can be realized only by gripping the top cross rod of the handle 1 and the top cross rod of the release taper shank 41 with force, so that the eccentric taper 9 is released.
Of course, the annular handle 1 may be fixedly connected with the support tube 2, the support tube 2 does not extend into the annular handle 1, and the taper shank 41 is slidably connected with the annular handle 1. In short, the release lever 41 and the handle 1 can move relatively, so that the brake cable can be pulled.
Referring to fig. 3, the two clasps 31 may be hinged at the top end or may be hinged at the bottom end, preferably in a bottom end hinged configuration. Because of the hinged bottom end, when the inner wire 46 of the first brake cable 44 is pulled, the two buckles 31 are retracted more greatly, and the working efficiency is improved.
Further, referring to fig. 2 and 3, one end of the support tube 2, which is close to the buckle 31, is fixedly connected with a conical head 5, the bottom end surface of the conical head 5 is concave to form a movable cavity 51, the two buckles 31 can move in the movable cavity 51 in an opening and closing manner, and the hinge shafts of the two buckles 31 are fixed at the bottom end of the conical head 5. The conical head 5 is arranged to facilitate the insertion of the buckle 31 into the hole 81 (see fig. 4) where the eccentric cone 9 is located, and also to protect the buckle 31. Correspondingly, the pushing sleeve 42 is sleeved outside the conical head 5, and the reset spring 43 is arranged between the conical head 5 and the pushing sleeve 42; one end of a second inner wire 48 of the second brake cable 45 is connected to the cone-releasing handle 41, and the other end is connected to the cone head 5. Preferably, in the normal state, a part of the pushing sleeve 42 is sleeved on the conical head 5, and the return spring 43 is positioned in the pushing sleeve 42. An annular end cover can be welded at the end part of the pushing sleeve 42 away from the conical head 5, one end of the reset spring 43 is abutted with the conical head 5, and the other end is abutted with the annular end cover.
Preferably, one end of the inner wire 46 of the first brake cable 44 connected with the buckle 31 penetrates out from the middle of the conical head 5, so that when the inner wire 46 pulls the two buckles 31, the stress is symmetrical and uniform, and the use is more convenient.
The scheme is mainly used in the condition that the eccentric cone 9 is easy to pull out, in reality, some eccentric cones 9 are clamped tightly in the holes 81 and are difficult to directly pull out by manpower, so that the hook and pull-out dual-purpose device for replacing the eccentric cone of the railway turnout further comprises a pull-out assisting device 6 as shown in fig. 1. The pulling-assisting device 6 comprises a diamond-shaped telescopic frame 61, a transverse screw rod 62, a crank 63 and a supporting cylinder 7. Four sides of the diamond-shaped expansion frame 61 are mutually hinged, four corners of the diamond-shaped expansion frame 61 are respectively provided with a connecting plate 64, and the four corners are respectively a top corner, a bottom corner and two opposite corners. The connecting plate 64 may be a slot-shaped plate, four sides of the diamond-shaped expansion frame 61 may also be slot-shaped plates, the four sides are hinged with the connecting plate 64, and the hinge shaft is arranged on the connecting plate 64. The connecting plate 64 at the top corner of the diamond-shaped expansion frame 61 is fixedly connected with the supporting tube 2, and the connecting plate 64 at the bottom corner is sleeved on the supporting tube 2.

When in use, the cone head 5 is extended into the hole 81, and the clamp 31 clamps the eccentric cone 9; shaking the crank 63 to make the supporting cylinder 7 prop against the hole 81; the crank 63 is continuously rocked to vertically extend the diamond-shaped telescopic frame 61, the conical head 5 is continuously lifted, and finally the eccentric cone 9 is pulled out.
Further, the transverse screw rod 62 is provided with a reverse thread, one end of the transverse screw rod 62 far away from the crank 63 is in threaded connection with the connecting plate 64, when the crank 63 is rocked, the two connecting plates 64 move towards the center along the transverse screw rod 62 at the same time, so that the deformation speed of the diamond-shaped telescopic frame 61 is improved, and the working efficiency is improved.
Preferably, the middle part of the vertical supporting tube 2 is provided with an avoidance ring 21 for avoiding the transverse screw rod 62, and the avoidance ring 21 has a certain length in the vertical direction, so that when the diamond-shaped expansion frame 61 is vertically lengthened, the transverse screw rod 62 can also play a role in avoiding after moving downwards.

In addition, in order to facilitate the carrying of the whole dual-purpose device, the crank 63 and the transverse screw rod 62 are hinged, and when not in use, the crank 63 is folded back and overlapped with the diamond-shaped telescopic frame 61, thereby saving space and protecting the crank 63 (not shown).
The working process comprises the following steps:
in the first step, the spike cover plate on the eccentric cone 9 is removed, the eccentric cone 9 to be replaced is exposed, and the cone head 5 of the device is extended into the hole 81 where the eccentric cone 9 is positioned until the buckle 31 is completely embedded into the bottom end groove 91 of the eccentric cone 9.
And secondly, vertically lifting the handle 1, and pulling out the eccentric cone 9 to be replaced.
If the outer wall of the eccentric cone 9 to be pulled out is firmly adhered to the inner wall of the hole 81, when the eccentric cone 9 is difficult to be pulled out by hand, the crank 63 is rotated, the supporting cylinder 7 and the cone head 5 are relatively displaced, and the distance between the supporting cylinder 7 and the cone head 5 is shortened until the eccentric cone 9 is pulled out.
And thirdly, the eccentric cone 9 is also clamped on the buckles 31, the handles 1 and the cone removing handles 41 are tightly clamped, the two buckles 31 are retracted, the clamping hooks 33 are separated from the bottom grooves 91 of the eccentric cone 9, and meanwhile, the sleeve 42 is pushed to push the eccentric cone 9 out of the cone head 5 buckle 31.
And fourthly, reversely rotating the crank 63 to restore the original position so as to pull out the next eccentric cone 9.
In conclusion, the device can more conveniently and more laborsaving finish the extraction task of the eccentric cone 9, and has the characteristics of small volume, light weight, convenient carrying, easy operation and strong universality.

The eccentric cone 9 which is easy to draw can be continuously circulated according to three steps of hooking, pulling and releasing, and the body only needs to be kept upright, and the operation can be completed by matching with the tightness of the handle 1. The action amplitude is small, labor is saved, and the operation is convenient; the eccentric cone 9 which is not easy to draw also has the characteristics of rapidness and labor saving, can not cause collateral damage to other components of the turnout, is equivalent to a dual-purpose turnout, and is very convenient to work and carry.
The volume is small: the whole instrument is approximately sheet-shaped, has the length of about 90cm and the width of about 50cm (the instrument can be deformed in a telescopic way in the width direction, so that the occupied space can be saved). Compared with the similar products (hook rod or high-speed railway fork eccentric cone puller), the size is smaller, and the integrity of the booster is good.
Commonality: because the device can satisfy two kinds of operating modes of easily colluding and being difficult for colluding simultaneously, compare the eccentric awl extractor of lever principle among simple hook pole and the background art that is used often, the device has better commonality.
In addition, the device also has the cone removing function which is not provided for other instruments, namely: after the replaced eccentric cone 9 is extracted, a worker does not need to manually take off the old eccentric cone 9 from the cone head 5, but still only needs to keep the body upright, the hand handle 1 is held tightly, the old eccentric cone 9 falls off from the cone head 5 at the bottom end of the device, and convenience is provided for the extraction work of the next eccentric cone 9 without any time delay.
