Each set of steel cables passes through a corresponding wire outlet hole, and the three sets of steel cables are connected to a connecting plate. By respectively passing the three sets of steel cables through the wire outlet holes at the three top corners of the tripod and extending them downward to connect with the connecting plate, the three sets of steel cables, the tripod, and the connecting plate are combined to form a vertebral structure. The vertebral structure is relatively stable, effectively reducing the shaking of objects at the apex of the vertebral structure and preventing the suspended objects from falling off.

[0004] However, this patent still has certain shortcomings in actual use.

[0026] In this embodiment, the lifting assembly 400 is used to place components used in the construction of the box-type steel structure pedestrian overpass and to enable it to maintain a stable structure.

[0027] like Figure 1 、 Figure 2 and Figure 4 As shown, the lifting assembly 400 includes a loading box 401, four lifting rings 402 fixed to the top of the loading box 401, a connector 403 hung on the inner side of the lifting ring 402, four groups of fixed blocks 404 fixed to the bottom of the connecting plate 5, a limit box 405 fixed between the bottoms of the fixed blocks 404 of the same group, a screw 406 rotatably connected to the inner top wall of the limit box 405 through a bearing, a rotating rod 407 fixed to the top of the screw 406, a hexagonal block 408 fixed to the top of the rotating rod 407, a square block 409 threadedly connected to the outside of the screw 406, a square hole 410 opened at the bottom of the limit box 405 for the corresponding square block 409 to slide, a threaded groove 411 opened at the top of the square block 409, and an abutment pad 412 bonded to the bottom of the square block 409.

[0028] It should be noted that the loading box 401 is located at the bottom of the connecting plate 5, and the top of the connecting member 403 is fixed to the bottom of the connecting plate 5. The connecting member 403 is composed of a hook and a steel cable, so that the hook can be normally hung inside the corresponding lifting ring 402, so that the connecting plate 5 can be connected to the loading box 401 through four connecting members 403.

[0029] In addition, each group of fixed blocks 404 has four in number, the top of the rotating rod 407 passes through the top of the corresponding limit box 405, and the hexagonal block 408 is located at the top of the corresponding limit box 405, which is convenient for rotating the rotating rod 407 through the hexagonal block 408 to rotate, thereby driving the screw 406 to rotate.

[0030] At the same time, the thread groove 411 is threadedly connected to the corresponding screw 406, so that the square block 409 can be threadedly connected to the outside of the screw 406 through the thread groove 411, and under the limiting action of the square hole 410, when the screw 406 rotates, it can drive the square block 409 to move up and down, and the bottom of the abutment pad 412 can abut against the top of the loading box 401, so that after the abutment pad 412 is in contact with the top of the loading box 401, it can play a limiting role on it, making the loading box 401 not easy to shake.

[0031] In this embodiment, the hoisting assembly 300 is a structure used to hoist and lift the lifting assembly 400.

[0032] like Figure 1 and Figure 3 As shown, the lifting assembly 300 includes a driving box 301 fixed to the top of the support plate 2, a driving mechanism 302 fixedly installed on the front of the driving box 301, a driving rod 303 rotatably connected to the inner side of the driving box 301 through a bearing, three winding rollers 304 fixedly installed on the outside of the driving rod 303, a steel cable 305 wound around the outside of the winding roller 304, an installation box 306 fixed to the top of the support plate 2, three classification boxes 307 fixed to the inside of the installation box 306 and with an opening on the left side, and three extension holes 308 respectively opened between the bottom of the three classification boxes 307 and the bottom of the installation box 306.

[0033] It should be noted that the output shaft of the driving mechanism 302 passes through the front of the driving box 301 and is fixedly connected to one end of the front of the driving rod 303, so that the driving mechanism 302 can drive the driving rod 303 to rotate, wherein the driving mechanism 302 is composed of a servo motor and a reducer, the output shaft of the servo motor is fixedly connected to the input shaft of the reducer, and the output shaft of the reducer is fixedly connected to the driving rod 303, so that the reducer can reduce the load of the servo motor, so that the driving mechanism 302 can stably drive the driving rod 303 to rotate.

[0034] In addition, the left side of the installation box 306 is fixedly connected to the right side of the drive box 301, and three connecting holes are opened between the left side of the installation box 306 and the right side of the drive box 301. The three connecting holes are respectively connected to the interior of the three classification boxes 307. The ends of the three steel cables 305 pass through the inner sides of the corresponding connecting holes in turn and extend to the interior of the corresponding classification boxes 307, and extend to the outside through the interior of the corresponding extension holes 308. The bottom end of the steel cable 305 is fixedly installed on the top of the connecting plate 5, and the bottom ends of the three steel cables 305 are distributed in a triangular shape on the top of the connecting plate 5, so that the steel cable 305 can normally extend to the outside and connect with the connecting plate 5, so as to drive the connecting plate 5 to be lifted or lowered.

[0035] At the same time, the inner left side wall of the extension hole 308 is connected to a guide roller for slidingly guiding the steel cable 305 through a rotating shaft, so that the steel cable 305 can slide under the action of the guide roller, preventing the steel cable 305 from directly contacting the corners of the extension hole 308.

[0036] The working principle of the above embodiment is:

[0037] When lifting the components of the box-type steel structure pedestrian bridge, the required template or steel structure is placed inside the loading box 401, and the connecting piece 403 is hung on the inner side of the corresponding lifting ring 402. The driving mechanism 302 is started to drive the driving rod 303 to rotate, so that the winding roller 304 can reel in or release the steel cable 305. The connecting plate 5 can be pulled by the steel cable 305 to lift the loading box 401, so that the loading box 401 is away from the ground and the connecting piece 403 is tightened. The driving mechanism 302 is closed, and the hexagonal block 408 is rotated. The corresponding screw rod 406 is driven to rotate by the rotating rod 407, so that the square block 409 can be driven by the screw rod 406 to move up and down through the thread groove 411 under the limiting action of the corresponding square hole 410, thereby making the abutment pad 412 fit against the top of the loading box 401. The loading box 401 is restrained by the square block 409 and is not easy to shake. The driving mechanism 302 is started again to continue the lifting work.

[0038] Compared with the existing technology, the box-type steel structure pedestrian bridge hoisting and stabilization device can further improve the stability of the hoisting structure through the coordinated use of the column 1, the support plate 2, the hoisting assembly 300 and the lifting assembly 400, so that the hoisted structure can also be given a stable and effective anti-sway effect, so that it also has good stability, which is conducive to the hoisting and lifting of steel structure parts and formwork, thereby facilitating the stable construction of the box-type steel structure pedestrian bridge, and effectively improving the practicality of the hoisting device, solving the problem that the hoisting structure of the existing steel structure hoisting device cannot be effectively stabilized during actual use.
