[0025] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0026] like Figures 1 to 3As shown, a large steel structure transfer tool includes a grid platform, the grid platform includes a first grid 1, a second grid 2 and a plurality of support components, the orthographic projection area of the first grid 1 is larger than the orthographic projection area of the second grid 2, the top of the second grid 2 is fixedly arranged at the center position of the bottom of the first grid 1, the second grid 2 can be fixed at the center position of the bottom of the first grid 1 by welding, and the plurality of support components are evenly fixedly arranged on both sides of the bottom of the first grid 1 and the bottom of the second grid 2, each of the support components includes a support leg 3 and a shock-absorbing universal wheel 4, one end of the support leg 3 is fixedly connected to the bottom of the first grid 1 or the bottom of the second grid 2, and the bottom of each support leg 3 is fixedly connected to the shock-absorbing universal wheel 4. See FIG. Figure 1 In this embodiment, there are 6 support assemblies, and one end of the two support legs 3 is fixedly connected to the bottom of the first grid 1, and one end of the four support legs 3 is evenly fixed to the bottom of the second grid 2. The first grid 1 is provided with a plurality of first frame-shaped slots, and the second grid 2 is provided with a plurality of second frame-shaped slots. The design of the first frame-shaped slots reduces the overall weight of the first grid 1, and the design of the second frame-shaped slots reduces the overall weight of the second grid 2, thereby reducing the overall weight of the transfer tooling and effectively preventing its own weight from affecting the transfer of the truss 8. In addition, the weight of the second grid 2 in this embodiment is greater than the weight of the first grid 1, so that the center of gravity of the transfer tooling is lowered.
[0027] The large steel structure transfer tooling of this embodiment is designed to adopt the first grid 1 and the second grid 2, and the top of the second grid 2 is fixedly set at the center position of the bottom of the first grid 1, so that the overall center of gravity is low. Because the size of the truss 8 is usually designed to be larger (the size of the truss 8 in this embodiment is 30*60m, and the height is 2m), and the size of the first grid 1 in this embodiment is larger than the size of the second grid 2, when the truss 8 is placed on the top of the first grid 1, the contact area between the two is large enough. When the transfer tooling is on the transfer truss 8, because of its small overall weight and the overall center of gravity, it can not only achieve stable transfer of the truss 8, but also effectively improve the transfer speed and efficiency. The transfer tooling is also designed to adopt support legs 3 and shock-absorbing universal wheels 4, which not only play the role of supporting the first grid 1, the second grid 2 and the truss 8; at the same time, when the working ground is uneven, the shock-absorbing universal wheels 4 can also play a shock-absorbing role, further improving the stability of the transfer tooling during transfer.
[0028] The large-scale steel structure transfer tooling implemented in this invention has a simple structure and is easy to use. It can meet the transportation requirements of large-scale steel structure scaffolding of different specified sizes, and effectively improves the transfer efficiency and economic benefits.
[0029] As an implementation method, the first grid 1 includes a first frame 11 and a plurality of first cross bars 12 and a first vertical bar 13. The plurality of first cross bars 12 and first vertical bars 13 are evenly fixedly arranged on the frame opening of the first frame 11 to form a plurality of first frame-shaped slots. The orthographic projection area of the first frame 11 is larger than the orthographic projection area of the second grid 2. The top of the second grid 2 is fixedly arranged at the center position of the bottom of the first frame 11. One end of the support leg 3 is fixedly connected to the bottom of the first frame 11. The first grid 1 of this embodiment can be formed in one piece or welded. Furthermore, a first reinforcing rod is arranged in the first frame-shaped slot located outside the second grid 2. The first reinforcing rod is a straight rod 14 or a V-shaped rod 15. The arrangement of the straight rod 14 and the V-shaped rod 15 enhances the structural strength of the first grid 1.
[0030] As an implementation method, the first frame 11 is provided with embedded grooves on all sides, that is, a plurality of first frame-shaped grooves located on the four sides of the first frame 11 have inwardly recessed notches. The embedded grooves are designed to prevent people from bumping into the first grid frame 1 when placing the truss 8 on top of the first grid frame 1.
[0031] As an implementation method, the second grid 2 includes a second frame 21 and a plurality of second cross bars 22 and a second vertical bar 23. The plurality of second cross bars 22 and second vertical bars 23 are evenly fixedly arranged on the frame opening of the second frame 21 to form a plurality of second frame-shaped slots. The orthographic projection area of the second frame 21 is smaller than the orthographic projection area of the first grid 1. The top of the second frame 21 is fixedly arranged at the center position of the bottom of the first grid 1. One end of the support leg 3 is fixedly connected to the bottom of the second frame 21. The second grid 2 of this embodiment can be formed in one piece or by welding. The orthographic projection area of the second frame 21 is smaller than the orthographic projection area of the first frame 11. The top of the second frame 21 is fixedly arranged at the center position of the bottom of the first frame 11.
[0032] Furthermore, a second V-shaped reinforcing rod 24 or a cross-shaped reinforcing rod 25 is fixedly disposed in the second frame-shaped slot. The second V-shaped reinforcing rod 24 and the cross-shaped reinforcing rod 25 enhance the structural strength of the second grid 2.
[0033] As an implementation method, a plurality of first connecting rods 6 are evenly and fixedly connected between the top of the second grid 2 and the center of the bottom of the first grid 1. Figure 1 A first connecting rod 6 is arranged between the second grid 2 and the first grid 1, further lowering the overall center of gravity. After the overall center of gravity is lowered, the transfer tooling will not come into contact with the working ground to affect its own movement.
[0034] Furthermore, a reinforcement strip 61 or a first V-shaped reinforcement rod 62 is obliquely fixedly connected between two adjacent first connecting rods 6. The arrangement of the reinforcement strip 61 and the first V-shaped reinforcement rod 62 enhances the structural connection strength between the second grid 2 and the first grid 1.
[0035] As an implementation method, a plurality of second connecting rods 7 are evenly and fixedly connected between the two sides of the second grid 2 and the bottom of the first grid 1. The provision of the second connecting rods 7 further enhances the structural connection strength between the second grid 2 and the first grid 1.
[0036] As an implementable embodiment, the transfer tool further includes a module car 5, and the center position of the bottom of the second grid 2 is fixedly set on the module car 5. The second grid 2 in this embodiment can be fixed on the module car 5 by welding. Among them, the module car 5 is a prior art and will not be described in detail here. When the module car 5 is started, it drives the entire transfer tool and the truss 8 thereon to move.
[0037] The process of transferring the truss 8 of the large steel structure transfer tooling is as follows: the center of the bottom of the second grid 2 is welded and fixed on the module vehicle 5, and the top of the second grid 2 is welded and fixed to the center of the bottom of the first grid 1. When the truss 8 is placed on the top of the first grid 1, when the module vehicle 5 is started, the entire transfer tooling and the truss 8 thereon are driven to move. At the same time, the support legs 3 and the shock-absorbing universal wheels 4 play a role in supporting the first grid 1, the second grid 2 and the truss 8. When encountering an uneven working surface, the shock-absorbing universal wheels 4 can also play a shock-absorbing role, further improving the stability of the transfer tooling during transfer.
[0038] The embodiments described above are only preferred embodiments of the present invention and are only used to explain the present invention, not to limit the scope of implementation of the present invention. For those skilled in the art, other implementation methods can certainly be easily made by replacement or modification based on the technical contents disclosed in this specification. Therefore, all changes and improvements made to the principles and process conditions of the present invention should be included in the scope of the patent application of the present invention.
