DETAILED DESCRIPTION

Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

The first implementation method:

Fig. 1-Fig. 5 show a hoisting device for large-span steel structure construction, including a base 1, a swivel seat 2 is installed on the top of the base 1, a boom 3 is installed on one end of the swivel seat 2, and the boom 3 is used to hoist the steel structure. The top of the base 1 is fixedly connected with an upper seat 4, and the upper seat 4 covers the outside of the swivel seat 2. The top of the upper seat 4 is fixedly connected with a cylinder 5, and the center point of the cylinder 5 and the center point of the rotating shaft of the swivel seat 2 are on the same straight line. Three mounting frames 501 are fixedly connected to the cylinder 5, and the interiors of the three mounting frames 501 are respectively fixedly connected with an upper regulator, a middle regulator and a lower regulator. The upper regulator, the middle regulator and the lower regulator all include a shell 6, and the outer The inner wall of the shell 6 is fixedly connected to a pan-rotating motor 601, the output end of the pan-rotating motor 601 is fixedly connected to a shaking head 602, a rotating rod 603 is rotatably connected between the inner walls at both ends of the shaking head 602, the outer wall of one end of the shaking head 602 is fixedly connected to a vertical motor 604, the output end of the vertical motor 604 is fixedly connected to one end of the rotating rod 603, and also includes a distance sensor 7, an upper indicating laser light 8, and a lower indicating laser light 9. The distance sensor 7, the upper indicating laser light 8, and the lower indicating laser light 9 are respectively fixedly connected to the rotating rods 603 on the upper regulator, the middle regulator, and the lower regulator, and also includes a first calibration rod 11 and a second calibration rod 12.

When the upper regulator is started to align the distance sensor 7 with the first calibration rod 11, the line between the distance sensor 7 and the first calibration rod 11 is set to A1, the vertical line of the first calibration rod 11 is set to A2, and the vertical line between the distance sensor 7 and A2 is set to A3. A1, A2 and A3 form a right triangle. If the length of A1 and the angle between A1 and A3 are known, the length of A3 can be calculated.

The light emitted by the upper indicating laser lamp 8 is set to B1, the vertical line of the upper indicating laser lamp 8 is set to B2, the vertical line adjacent to B2 is set to B3, and B3 is equal to A3. Knowing the lengths of B3 and B2, the length of B1 can be calculated, and then the angle between B1 and B2 can be calculated. The irradiation angle of the upper indicating laser lamp 8 is adjusted to be equal to the angle between B1 and B2. At this time, the connection point between B1 and B3 is set to C1.

Similarly, when the distance sensor 7 is aligned with the second calibration rod 12, C2 can be calculated.

The number of connection points of the steel structure is set to two, and after obtaining C1 and C2, the two connection points of the steel structure are aligned with C1 and C2 respectively.

Before hoisting, the first calibration rod 11 and the second calibration rod 12 need to be fixed on the steel frame, and the first calibration rod 11 and the second calibration rod 12 are perpendicular to the ground.

Through the above settings, the vertical line from C1 to the rotation axis of the swivel seat 2 is equal to the vertical line from the first base point to the rotation axis of the swivel seat 2, and the vertical line from C2 to the rotation axis of the swivel seat 2 is equal to the vertical line from the first base point to the rotation axis of the swivel seat 2. In this way, when the boom 3 is hoisting the steel structure, it only needs to complete the lifting and rotating actions of the steel structure to hoist the steel structure on the steel frame, and no other devices are needed to assist in the hoisting, thereby improving the hoisting accuracy.

The connection points on the steel frame are transferred to the ground in the form of light spots through the upper indicating laser light 8 and the lower indicating laser light 9, so that the steel structure can complete the alignment of the connection points on the ground. Compared with the adjustment work on the steel frame, it not only improves the convenience of adjustment, but also improves the safety of the staff.

When the upper regulator, the middle regulator and the lower regulator are working, the horizontal motor 601 can be started to drive the shaking head 602 to rotate in the horizontal direction. When the vertical motor 604 is started, it can drive the rotating rod 603 to rotate in the vertical direction, so as to control the distance sensor 7, the upper indicating laser light 8 and the lower indicating laser light 9 to rotate at different angles.

The second implementation method:

Figures 1 and 3-6 show a hoisting device for large-span steel structure building construction. Different from the first embodiment, when the upper indicating laser light 8 and the lower indicating laser light 9 rotate, the emitted light can form an aperture, and are respectively set to C11 and C21; when the upper indicating laser light 8 and the lower indicating laser light 9 rotate, the translation motor 601 is started to drive the upper indicating laser light 8 and the lower indicating laser light 9 to rotate at high speed, and the two connection points of the steel structure can be aligned with any point of C11 and C21. Through the above-mentioned setting, the convenience of the steel structure connection point alignment can be further increased, and the construction difficulty can be reduced.

The laser colors emitted by the upper indicating laser light 8 and the lower indicating laser light 9 are opposite, and there are a plurality of upper indicating laser lights 8 and lower indicating laser lights 9. Through the above arrangement, the two connection points of the steel structure can be distinguished by the difference in color between the upper indicating laser light 8 and the lower indicating laser light 9, thereby avoiding the situation where the connection points of the steel structure are opposite.

The vertical line of the steel structure connection point is set to D1, and the line between the upper indicating laser light 8 and the top of D1 is set to F1. Knowing the lengths of D1 and B1 and the angle between D1 and B1, the angle G1 between F1 and B1 can be calculated, and then the upper indicating laser light 8 is driven to rotate by G1, at which time B1 coincides with F1.

The connection point of the steel structure is usually not flush with the ground, which causes C1 irradiated on the connection point of the steel structure to be raised, with a certain error. Through the above setting, the light emitted by the upper indicating laser lamp 8 can be automatically calibrated according to the height of the connection point of the steel structure, so that the light emitted by the upper indicating laser lamp 8 is irradiated on the connection point of the steel structure, further improving the convenience of locating the connection point of the steel structure.

Similarly, the irradiation position of the lower indicator laser light 9 can be calculated and adjusted.

The upper regulator, the middle regulator and the lower regulator also include a gyroscope sensor, which is used to obtain the rotation angle of the rotating rod 603. The middle regulator and the lower regulator also include a height sensor, which is used to obtain the vertical height of the rotating rod 603 from the ground. The top of the cylinder 5 is also fixedly connected to a laser radar sensor, which is used to position the first calibration rod 11 and the second calibration rod 12.

After the laser radar sensor locates the first calibration pole 11 and the second calibration pole 12 , the pitch angle and the azimuth angle of the distance sensor 7 are calculated, and a rotation angle is provided for the distance sensor 7 to align with the first calibration pole 11 and the second calibration pole 12 .

It also includes two laser receivers 13 . A lifting rod 10 is fixedly connected between the upper seat 4 and the cylinder 5 . The output end of the lifting rod 10 is fixedly connected to the bottom end of the cylinder 5 .

After the position of the steel structure is determined, the two laser receivers 13 can be installed on the two fixed points of the steel structure respectively. At this time, when the upper indicating laser light 8 and the lower indicating laser light 9 are irradiated on the laser receiver 13, during the hoisting process of the steel structure, the steel structure gradually rises. At this time, the lifting rod 10 is started to drive the cylinder 5 to rise synchronously. When the steel structure is rotating, the upper indicating laser light 8 and the lower indicating laser light 9 rotate synchronously, so that the upper indicating laser light 8 and the lower indicating laser light 9 are always irradiated on the lifting rod 10. If the lifting rod 10 does not receive the laser signal, it indicates that the connection point is offset, and adjustments can be made in time, so that the connection point of the steel structure can be monitored during the hoisting process of the steel structure, thereby further improving the accuracy of the steel structure hoisting.

In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
