[0028] 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.

[0029] Please see Figures 1-6 This utility model provides a technical solution:

[0030] To address the problems existing in the prior art, this embodiment provides the following technical solution: a high-strength steel structure support structure for a crane main beam to prevent bending, comprising a main beam body 1; an anti-bending mechanism located on the inner side and lower part of the main beam body 1, which strengthens the connection between the main beam bodies 1, thereby increasing the rigidity of the main beam body 1 and preventing bending; a connecting and fixing mechanism located on the left and right outer sides of the main beam body 1, which strengthens the connection between the main beam body 1 and the side beams 5, effectively preventing the main beam body 1 from becoming loose during installation; and an adjustable mechanism located above the main beam body 1, which allows for flexible adjustment of the support for the main beam body 1, thereby greatly improving the flexibility of support adjustment.

[0031] like Figure 4 , Figure 5 and Figure 6 As shown, by installing the first connecting block 2 on the upper left and right sides of the main beam body 1 and the second connecting block 3 on the lower left and right sides of the main beam body 1, the first connecting block 2 and the second connecting block 3 can be inserted into the connecting slot 4 opened inside the side beam 5. Then, the rotating part 6 can be rotated inward so that its upper side rotates into the inside of the first connecting block 2. Then, the first bolt 7 is inserted into the first connecting block 2 and the rotating part 6 and tightened to fix them, so that the main beam body 1 and the side beam 5 can be firmly connected. Secondly, the supporting diagonal rods 8 are set on the left and right sides of the outer side of the main beam body 1, and the outer side of the supporting diagonal rods 8 is fixedly connected to the side beam 5, which further strengthens the firmness of the connection between the main beam body 1 and the side beam 5.

[0032] like Figure 2 and Figure 6As shown, a bottom support rod 10 is fixedly installed below the main beam body 1. The bottom support rod 10 can support the bottom of the main beam body 1. A connecting rod 11 is set inside the bottom support rod 10. The connecting rod 11 is designed in an "X" shape, which further enhances the support of the bottom support rod 10. In addition, a bracket 9 is set inside the main beam body 1. The bracket 9 also enhances the fixation of the connection between the main beam bodies 1.

[0033] like Figure 5 and Figure 6 As shown, a fixed frame 17 is installed above the main beam body 1. Connecting frames 12 are installed at equal intervals inside the fixed frame 17. A movable frame 13 is slidably arranged on the upper outer side of the connecting frame 12. Positioning holes 14 are opened inside the left and right sides of the connecting frame 12, so the distance between the movable frames 13 can be adjusted. After the position of the movable frame 13 is adjusted, the second bolt 15 can be inserted into the positioning hole 14 and the interior of the movable frame 13 for fixation, which greatly improves the flexibility of the movable frame 13 adjustment. In addition, telescopic rods 16 are installed at equal intervals between the movable frames 13. The telescopic rods 16 are telescopic and can extend and retract with the movement of the movable frame 13, which can further strengthen the fixation of the connection between the main beam bodies 1. That is, the components set on the inner, lower and upper sides of the main beam body 1 can effectively strengthen the strength of the connection between the main beam bodies 1 and avoid bending after use.

[0034] The working principle of the high-strength steel structure support for the crane main beam that prevents bending is as follows: The main beam body 1 is connected to the side beam 5 on the outside. Multiple firmly connected components are set between the main beam body 1 and the side beam 5 to strengthen the connection between them. At the same time, multiple components are set below, inside and above the main beam body 1 to strengthen the connection between the main beam bodies 1, which can effectively prevent the main beam body 1 from bending. Furthermore, the components set on the upper side can be adjusted, which further improves the flexibility of support adjustment.
