Description

Technical Field

[0001] The utility model relates to the technical field of arch bridge cantilever construction, in particular to an arch bridge cantilever construction hoisting structure. Background Art

[0002] Cantilever construction methods for reinforced concrete arch bridges are divided into two categories: cantilever assembly and cantilever casting. The cantilever casting method primarily utilizes a hanging basket cantilever casting method. Based on current domestic and international technology, it can be further divided into the tower-slant-stayed and buckled-hanging method and the cantilever truss casting method. Currently, fewer than ten arch bridges constructed using the cantilever casting method have been completed in China, all of which utilize the tower-slant-stayed and buckled-hanging method. Due to varying construction conditions and the lack of technical theory, the overall process is still in its infancy.

[0003] During the construction of an arch bridge cantilever, a lifting structure is used to lift some materials. The overall length of the existing lifting structure is usually fixed, which makes it inconvenient to increase the overall length of the lifting structure according to the length of the material. This has certain limitations. For this reason, we propose a lifting structure for the arch bridge cantilever construction. Utility Model Content

The two extension plates are both connected to the main board through a positioning mechanism.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, a lifting plate is provided above the main board, and connecting ropes are fixedly connected to the middle of the four sides of the lifting plate.

[0008] Furthermore, the lower end of each connecting rope is fixedly connected to the upper end surface of the main board, and the upper end surface of the lifting plate is fixedly connected with a lifting ring.

[0034] The utility model provides an arch bridge cantilever construction hoisting structure. When in use, the whole structure is hung on the hook of the hoisting equipment through the lifting ring 1, and then the two rotating handles 9 below the main board 5 are rotated respectively.

Then, the two extension plates 4 can be pulled separately, so that the extension plates 4 pass through the limit slider. The function of the slot 13 and the limit slider 2 14 is to slide through the inner wall of the slot to limit the length, so that the overall length of the entire device can be lengthened and adjusted. After adjusting to the appropriate length, the threaded rod 12 is reversed by reversing the rotating handle 9, so that the threaded rod 12 drives the limit plug 11 to move in the opposite direction, so that the limit plug 11 slides into the limit slot 15, so that the adjusted extension plate 4 is limited, thereby completing the lengthening and adjustment of the overall use length of the lifting structure, and then it can be hung on the material under the action of the hook 7 so that the material can be lifted.
