The transportation of these materials requires construction material transportation and hoisting equipment to meet the needs of construction material transportation and hoisting.

[0003] Most construction material transport and hoisting equipment on the market has a fixed floor space for load-bearing support. Increasing the floor space for load-bearing support according to demand results in poor stability of the transport and hoisting equipment.

[0004] Therefore, a temporary steel trestle bridge construction material transportation and hoisting auxiliary equipment is needed. Utility Model Content

[0005] This utility model proposes an auxiliary equipment for transporting and hoisting construction materials for temporary steel trestle bridges. It solves the problem that existing construction material transport and hoisting equipment on the market has a fixed floor area for most of its load-bearing supports. However, increasing the floor area of ​​the load-bearing supports according to demand leads to poor stability of the transport and hoisting equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A temporary steel trestle construction material transportation and hoisting auxiliary equipment includes a base plate, a support frame fixed above the base plate, a handle fixed above the support frame, a hollow support plate on one side of the support frame, a threaded plate on the inner side of the hollow support plate, an arc-shaped positioning plate fixed to the side wall of the threaded plate, a first slide rail on the inner wall of the support frame, a first slider on the inner side of the first slide rail, a rack plate fixed to the side wall of the first slider, a push plate fixed to the side wall of the rack plate, a gear plate meshing with one side of the rack plate, a first connecting column fixed inside the gear plate, a first bearing at the connection between the first connecting column and the support frame, a first threaded column fixed to the other end of the first connecting column, a threaded groove threadedly connected to the outer periphery of the first threaded column, a lifting plate installed outside the threaded groove, a second slider fixed to the side wall of the lifting plate, and a second slide rail on the outer side of the second slider.

[0007] Preferably, a threaded bolt is fixed on the upper surface of the base plate, a threaded cap is threadedly connected to the outer periphery of the threaded bolt, and a weighting module is provided on the lower side of the threaded cap.

[0008] Preferably, the rack plate forms a sliding structure with the first slide rail via the first slider.

[0013] This utility model proposes an auxiliary device for transporting and hoisting construction materials for temporary steel trestle bridges. Compared with the prior art, the beneficial effects of this utility model are: 1. The temporary steel trestle bridge construction material transportation and hoisting auxiliary equipment is equipped with a rack plate and a gear plate. By pushing the push plate with external force, the rack plate can be moved. The movement of the rack plate can cause the gear plate to rotate, which indirectly drives the first threaded column to rotate. The rotation of the first threaded column can cause the lifting plate to rise and fall. During the lifting process, the hollow support plate and the arc-shaped positioning plate can be raised and lowered. The descent of the two sets of arc-shaped positioning plates can press and fix the base of the transportation and hoisting device, thereby indirectly increasing the load-bearing area and its own weight of the base, increasing the stability during use, and avoiding the situation where the area occupied by most of the load-bearing support of the construction material transportation and hoisting equipment is fixed, and the area occupied by the load-bearing support is increased according to the needs, resulting in poor stability of the transportation and hoisting equipment. 2. The temporary steel trestle bridge construction material transportation and hoisting auxiliary equipment is equipped with a second threaded column and a threaded plate. By turning the hand handle with external force, the second threaded column can be rotated. Through the threaded connection between the second threaded column and the threaded plate, the rotation of the second threaded column can move the threaded plate, which indirectly drives the arc-shaped positioning plate to move. Adjusting the distance between the two sets of arc-shaped positioning plates can facilitate the handling of bases of different widths of the transportation and hoisting equipment, increasing the practicality of the device.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4This utility model provides a technical solution: an auxiliary device for transporting and hoisting construction materials for a temporary steel trestle bridge, comprising a base plate 1, a support frame 2 fixed above the base plate 1, a handle 3 fixed above the support frame 2, a hollow support plate 4 on one side of the support frame 2, a threaded plate 5 on the inner side of the hollow support plate 4, an arc-shaped positioning plate 6 fixed to the side wall of the threaded plate 5, a first slide rail 7 on the inner wall of the support frame 2, a first slider 8 on the inner side of the first slide rail 7, and a rack plate 9 fixed to the side wall of the first slider 8. A push plate 10 is fixed to the side wall of plate 9. A gear plate 11 is meshed with one side of rack plate 9. A first connecting column 12 is fixed inside the gear plate 11. A first bearing 13 is provided at the connection between the first connecting column 12 and the support frame 2. A first threaded column 14 is fixedly connected to the other end of the first connecting column 12. A threaded groove 15 is threadedly connected to the periphery of the first threaded column 14. A lifting plate 16 is installed outside the threaded groove 15. A second slider 17 is fixed to the side wall of the lifting plate 16. A second slide rail 18 is provided on the outer side of the second slider 17.

[0018] Furthermore, a threaded bolt 19 is fixed on the upper surface of the base plate 1, and a threaded cap 20 is threadedly connected to the outer periphery of the threaded bolt 19. A weighting module 21 is provided on the lower side of the threaded cap 20.

[0019] Furthermore, the rack plate 9 forms a sliding structure with the first slider 8 and the first slide rail 7. When the push plate 10 is pushed by an external force, the rack plate 9 can be moved. The movement of the rack plate 9 can cause the gear plate 11 to rotate, which indirectly causes the first threaded column 14 to rotate. The rotation of the first threaded column 14 can cause the lifting plate 16 to rise and fall.

[0020] Furthermore, the first threaded column 14 is threadedly connected to the lifting plate 16 through the threaded groove 15. The lifting plate 16 is connected to the second slide rail 18 through the second slider 17 to form a sliding structure. The lifting plate 16 and the hollow support plate 4 form a fixed structure. During the lifting process, the lifting plate 16 can drive the hollow support plate 4 and the arc-shaped positioning plate 6 to lift. The descent of the two sets of arc-shaped positioning plates 6 can press and fix the base of the transport hoisting device, thereby indirectly increasing the bearing area and weight of the base, and increasing the stability during use.

[0021] Furthermore, the threaded bolt 19 and the threaded cap 20 form a detachable structure. The threaded cap 20 can be disassembled and assembled through the thread of the threaded bolt 19, thereby allowing multiple sets of weighting modules 21 to be added or removed at any time. The added weight can increase stability.

[0022] Furthermore, a second bearing 22 is provided on the top side wall of the hollow support plate 4, a hand crank 23 is provided on the inner side of the second bearing 22, a second threaded post 24 is fixed at the end of the hand crank 23, a second connecting post 25 is fixed at the other end of the second threaded post 24, a third slider 26 is fixed on the other side wall of the threaded plate 5, and a third slide rail 27 is provided on the outer side of the third slider 26. By rotating the hand crank 23 with external force, the second threaded post 24 can be driven to rotate. Through the threaded connection between the second threaded post 24 and the threaded plate 5, the rotation of the second threaded post 24 can move the threaded plate 5, indirectly driving the arc-shaped positioning plate 6 to move, adjusting the distance between the two sets of arc-shaped positioning plates 6, which is convenient for handling bases of different widths of transport and hoisting equipment.

[0023] Furthermore, the hand crank 23 forms a rotating structure with the hollow support plate 4 through the second bearing 22, and the second threaded column 24 forms a threaded connection with the threaded plate 5. The threaded plate 5 forms a sliding structure with the third slide rail 27 through the third slider 26. When the hand crank 23 is rotated by external force, the second threaded column 24 can be rotated. Through the threaded connection between the second threaded column 24 and the threaded plate 5, the rotation of the second threaded column 24 can move the threaded plate 5, which indirectly drives the arc-shaped positioning plate 6 to move, adjusting the distance between the two sets of arc-shaped positioning plates 6 to facilitate the handling of bases of different widths for transporting and hoisting equipment.

[0024] Working principle: First, by rotating the hand handle 23 with external force, the second threaded column 24 can be rotated. The rotation of the second threaded column 24 can move the threaded plate 5, which indirectly moves the arc-shaped positioning plate 6, adjusting the distance between the two sets of arc-shaped positioning plates 6. Second, by pushing the push plate 10 with external force, the rack plate 9 can be moved. The movement of the rack plate 9 can rotate the gear plate 11, which indirectly rotates the first threaded column 14. The rotation of the first threaded column 14 can raise and lower the lifting plate 16. During the raising and lowering process of the lifting plate 16, the hollow support plate 4 and the arc-shaped positioning plate 6 can be raised and lowered. The descent of the two sets of arc-shaped positioning plates 6 can press and fix the base of the transport hoisting device, thereby indirectly increasing the bearing area and its own weight of the base. Then, the threaded cap 20 can be disassembled and assembled through the thread of the threaded bolt 19, so that multiple sets of weighting modules 21 can be added or removed at any time. The added weight can increase stability.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
