[0023] Specifically, the controller 3 can control the start-up of the first motor 8, the hydraulic rod 13 and the cantilever crane 6, and the operator stays away from the danger zone. The first motor 8 can control the rotation of the threaded rod 9 and then control the movement of the second slide bar 5. There is a hydraulic rod 13 between the second slide bar 5 and the first slide bar 4 for control. First, the second slide bar 5 is controlled to move to the fixed ring position on one side of the large-span special-shaped structure to be hoisted. When the hydraulic rod 13 is started, the second slide bar 5 will remain stationary due to the threaded rod 9 and then push the first slide bar 4 to contract or extend, and then expand or shrink. When the first slide bar 4 moves to the fixed ring on the other side, the hydraulic rod 13 is stopped and the next operation is performed.

[0024] Reference Figure 1 and Figure 3 The right end of the hook 11 is slidably connected with an adjusting plate 18, and the upper and lower sides of the right end of the adjusting plate 18 are fixedly connected with baffles 15. The right end of the baffle 15 is fixedly connected with a plurality of springs 16, and the right ends of the springs 16 are fixedly connected to the inner wall of the hook 11. The inner wall of the hook 11 is slidably connected with a notched ring 17, and the outer wall of the notched ring 17 is provided with a plurality of limiting grooves, and the shape and size of the limiting grooves are consistent with the shape and size of the left end of the adjusting plate 18. The left end of the inner wall of the hook 11 is provided with a slide groove 14, and the shape and size of the slide groove 14 are consistent with the shape and size of the bottom of the notched ring 17.

[0025] Specifically, the lifting ring on the large-span special-shaped structural member is removed from the hook 11, the adjusting plate 18 is stretched outward and drives the baffle 15 to compress the spring 16. At this time, the adjusting plate 18 will be disengaged from the limiting groove on the notch ring 17 and restrict the notch ring 17. The notch ring 17 is disengaged from the slide groove 14. At this time, a notch will appear on the hook 11. When the size of the notch can pass through the lifting ring, the adjusting plate 18 is released. Under the reaction force of the spring 16, the adjusting plate 18 is pushed toward the notch ring 17. The notch ring 17 is fine-tuned to align the limiting groove with the adjusting plate 18. The adjusting plate 18 will be stuck in the limiting groove of the notch ring 17. At this time, the lifting ring can be disengaged from the notch of the hook 11.

[0026] Working principle: After the large-span special-shaped structural parts are produced, they are hoisted on the transport vehicle. First, the distance between the first slide bar 4 and the second slide bar 5 is determined according to the size of the large-span special-shaped structural parts to be transported. After the distance is determined, the controller 3 is used to start the first motor 8. At this time, the first motor 8 will drive the threaded rod 9 to rotate. When the threaded rod 9 rotates, it will drive the second slide bar 5 to move. At this time, the first slide bar 4 and the second slide bar 5 will be driven to move on the support frame 1. When the second slide bar 5 aligns with the lifting ring of one of the fixed points, the rotation of the first motor 8 is stopped. At this time, the controller 3 is used to start the hydraulic rod 13. Under the action of the hydraulic rod 13, the first slide bar 4 will be driven to move. When the first slide bar 4 touches the lifting ring of another fixed point, the operation of the hydraulic rod 13 is stopped. At this time, the cantilever crane 6 above is controlled to lower the lifting steel cable 7. When the highest point of the large-span special-shaped structure to be hoisted is reached, the cantilever crane 6 is separated for control. At this time, the lifting steel cable 7 is lowered again. When one of the lifting steel cables 7 touches the fixed point, the cantilever crane 6 connected to it is stopped, so that the distance between the hooks 11 can be adjusted when facing large-span special-shaped structures of different lengths. With their joint cooperation, the hooks 11 can be in a It can move within a certain range and adapt to the best fixing points of various large-span special-shaped structural parts, which improves practicality and stability. After all the lifting cables 7 are moved to the fixed points, the lifting rings of the fixed points are buckled into the notches of the hooks 11. At this time, the adjusting plate 18 is stretched outward and drives the baffle 15 to compress the spring 16. The adjusting plate 18 will leave the limiting groove. At this time, the notched ring 17 will slide and move to the slide groove 14. After the notched ring 17 enters the slide groove 14, the adjusting plate 18 is released and moves inward under the reaction force of the spring 16. At this time, the notched ring 17 is slightly adjusted to align the nearest limiting hole with the adjusting plate. 18, at this time, the adjusting plate 18 will be stuck into the limiting hole on the notch ring 17 and limit the movement of the notch ring 17, and the hook 11 will form a closed ring to imprison the ring therein, so that it can better fix the large-span special-shaped structural parts hung on it during operation, and prevent the large-span special-shaped structural parts from falling from the notch of the lifting hook during the rising process, thereby increasing safety. At this time, all the cantilever cranes 6 need to be started at the same time to lift the large-span special-shaped structural parts steadily, and then start the first motor 8 to move the position of the large-span special-shaped structural parts and place them steadily on the transport vehicle.
