[0002] The stiffened concrete structure and the steel structure are very common in today's building structure forms. The main characteristics of the engineering steel structure are large steel consumption and various structure forms. The application of steel structure forms such as steel pipe columns, transfer steel beams, transfer large trusses, and metal roofs has been very common, and the hoisting workload of the steel structure has also increased accordingly. Hoisting is the process of lifting and transporting items by a hoisting machine. Therefore, a detachable steel structure hoisting fixture is proposed to clamp the profiled steel for stable hoisting.

[0003] After retrieval, for example, the Chinese patent application with the application number CN201020658109.1 discloses a detachable steel structure hoisting fixture. This scheme is designed to be convenient for disassembly, flexible in adjustment and movement; it can speed up the hoisting progress, reduce the dependence on the tower crane, and shorten the construction period; it has high safety and accurate positioning; it is simple to manufacture, has a high turnover rate and strong versatility.

[0004] However, when the above scheme is used, two lifting splints are fixed through one end of the connecting plate, and similarly, two lifting splints are fixed at the other end of the connecting plate. However, the size of the connecting plate is fixed, so it is difficult to clamp the steel structure profiled steel with different lengths. The above scheme clamps the profiled steel through the grooves of the lifting splints. As is well known, in the hoisting work of many steel structures, there are not only profiled steels but also steel structure members such as steel pipes. The above scheme is difficult to hoist the steel structure members such as steel pipes, resulting in limited application scope. Summary of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a detachable steel structure hoisting fixture, and the technical problem to be solved is: it is difficult to adjust the clamping distance according to the size of the profiled steel, it is difficult to clamp the steel structure members such as steel pipes, and the application scope is limited.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a detachable steel structure hoisting fixture, including an operating platform:

[0010] In a preferred embodiment, an L-shaped transmission rod is movably arranged at the lower end of the rotating rod, and the rotating rod and the L-shaped transmission rod are hinged through a movable connection column.

[0011] In a preferred embodiment, a connecting plate is movably arranged between the four L-shaped transmission rods. The convex blocks on both sides of the connecting plate penetrate through the inner sides of the four L-shaped transmission rods. A threaded sleeve penetrates through the inner side of the connecting plate, and a threaded rod is threadedly connected inside the threaded sleeve.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art in the field of this lifting clamp without creative work belong to the scope of protection of the present utility model.

[0026] As Figure 1 and 2 shown, the present utility model provides a detachable steel structure lifting clamp, including an operating table 1: the upper end of the threaded rod 26 penetrates through the inner side of the operating table 1, a rotating handle 6 is fixedly arranged at the upper end of the threaded rod 26, a clamping plate 4 is fixedly arranged at the lower end of the L-shaped transmission rod 23, and an anti-slip pad 5 is fixedly arranged on one side of the clamping plate 4.

[0027] In order to make the applicable range wider and improve the practicability, a clamp holding device 2 capable of holding a variety of steel structure members is provided at the lower end of the operating table 1 for holding steel section bars and steel pipe utensils;

[0028] As Figure 3 shown, the clamp holding device 2 includes four hinge blocks 21 which are respectively and fixedly arranged on both sides of the operating table 1. A rotating rod 22 is hinged on the outer surface of the hinge block 21. An L-shaped transmission rod 23 is movably arranged at the lower end of the rotating rod 22. The rotating rod 22 and the L-shaped transmission rod 23 are hinged through a movable connecting column 24. A connecting plate 25 is movably arranged between the four L-shaped transmission rods 23. The convex blocks on both sides of the connecting plate 25 penetrate through the inner sides of the four L-shaped transmission rods 23. A threaded sleeve 27 penetrates through the inner side of the connecting plate 25. A threaded rod 26 is threadedly connected inside the threaded sleeve 27. A limiting block 28 is fixedly arranged at the lower end of the threaded rod 26. By holding the rotating handle 6, when clamping a steel structure member, by using the threaded connection of the threaded sleeve 27, the connecting plate 25 is driven to move up and down. Due to the movable connection between the L-shaped transmission rod 23 and the connecting plate 25, the L-shaped transmission rod 23 can be driven to rotate. Since the upper end of the L-shaped transmission rod 23 is limited by the rotating rod 22, the clamping and loosening of the clamping plate 4 at the lower end can be realized. The clamping plate 4 is in an L shape, so it can clamp H-shaped utensils and steel pipe utensils, and the practicability is improved as a whole.

[0029] Furthermore, in order to be able to clamp steel structure members of different sizes, a distance adjusting device 3 capable of adjusting the distance is provided at the upper end of the operating table 1 for adjusting the distance between two lifting clamps according to the length of the steel structure member;

[0030] As Figure 4 shown, the distance adjusting device 3 includes two connecting brackets 31. Connecting ears 32 are fixedly arranged on both sides of the connecting brackets 31. The connecting ears 32 are fixedly connected to the upper end of the operating table 1 through bolts. A limiting frame 33 is fixedly arranged at the upper end of the connecting brackets 31. A jack 34 is opened inside the limiting frame 33. A lifting plate 35 is movably arranged inside the limiting frame 33. A plurality of through holes 36 are opened inside the lifting plate 35. The through holes 36 are adapted to the jack 34. Bolts are inserted into the through holes 36 and the jack 34. Through the fixed connection between the connecting brackets 31 and the operating table 1, one end of the lifting plate 35 is inserted into the limiting frame 33. According to the length dimension of the steel structure member, the installation distance can be adjusted. Then, bolts are inserted into the through holes 36 and the jack 34 to realize the limit fixation of the lifting plate 35. Similarly, the other end of the lifting plate 35 is fixed to another lifting clamp. Thus, the steel structure member is clamped by the two lifting clamps, and the effect of clamping steel structure members of different sizes is realized as a whole.

[0031] The working principle is as follows: When the present utility model is in use, the lifting plate 35 is connected to the crane by a steel wire rope. Two of the present utility models are respectively movably arranged at both ends of the lifting plate 35. Lower the lifting plate 35 to align it with the steel structure member. Adjust the distance between the two present utility models according to the length dimension of the steel structure member by the distance adjusting device 3. Then, clamp the steel structure member by the clamp holding device 2. After the clamping is completed, pull the steel wire rope by the hoist to raise the lifting plate 35, thereby realizing the lifting work. Overall, the practicability is improved, the applicable range is increased, and various steel structure members can be clamped.

[0032] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
