Embodiment 1

[0033] Embodiment 1, refer to Figure 1-7 A hoisting device for bridge construction, comprising a bridge main body 5 and at least two hoisting platforms 1, the at least two hoisting platforms 1 are equally spaced above the bridge main body 5, and the center of the lower end of the hoisting platform 1 is respectively provided with a pulling rope mechanism The lower end of the pulling rope mechanism is movably connected with a horizontal bracket 7, and both ends of the bottom of the hoisting platform 1 are respectively provided with a traction mechanism. The horizontal bracket 7 is movably connected with a splint mechanism. 5 is close to clamping, the top ends of the splint mechanism are respectively connected with the bottom ends of the two traction mechanisms, wherein, at least two hoisting platforms 1 hoist both sides of the bridge main body 5 respectively. When in use, the hoisting platform 1 and the bridge The distance between the two ends of the main body 5 is equal to the...

Embodiment 2

[0034] Embodiment 2, refer to image 3 and Image 6, the traction mechanism includes a side traction cable 6, an upper pull ring 13 and a turning plate 12. The two ends of the side pulling cable 6 are respectively wound around the two upper pulling rings 13. It is integrally formed with the upper pull ring 13 , and the extended ends at the edges on both sides of the bottom surface of the hoisting platform 1 are respectively rotatably connected with the two turning plates 12 , and the pulling rope mechanism includes a hook 3 and a main traction cable 2 connecting the hook 3 and the hoisting platform 1 . , the horizontal support 7 is fixed with a pull-down ring 11 that is movably plugged into the hook 3, and the splint mechanism includes a first splint 4 and a second splint 8 that are arranged crosswise. The tops of the first splint 4 and the second splint 8 are The turning plate 12 is connected in rotation, and the ends of the first plywood 4 and the second plywood 8 that are ...

Embodiment 3

[0035] Embodiment 3, refer to Figure 1-7 , a method for using a hoisting device for bridge construction, comprising the following steps:

[0036] Step S1: first, connect the upper and lower sides of the pulling rope mechanism to the vertically overlapping hoisting platform 1 and the hook 3 respectively, then connect the tops of the two traction mechanisms to the two sides of the bottom surface of the hoisting platform 1 respectively, and connect the two The bottom end of the traction mechanism is respectively connected with the two top ends of the splint mechanism;

[0037] Step S2, then expand the spacing between the hooks 15 under the first plywood 4 and the second plywood 8 to be larger than the width of the bridge main body 5, set the two retracting hooks 15 on both sides of the bridge main body 5, and rotate the first plywood. 4 and the second splint 8 make the two draw hooks 15 and the lower side of the bridge main body 5;

[0038] Step S3, then insert the two rotatin...

Abstract

The hoisting device for bridge construction comprises a bridge body and at least two hoisting platforms, the at least two hoisting platforms are distributed above the bridge body at equal intervals, the centers of the lower ends of the hoisting platforms are each provided with a pull rope mechanism, and the lower ends of the pull rope mechanisms are movably connected with a horizontal support; traction mechanisms are arranged at the two ends of the bottom of the hoisting platform correspondingly, a clamping plate mechanism is movably connected to the horizontal support, the two ends of the bottom of the clamping plate mechanism are used for approaching and clamping a bridge body in a rotatable tightening mode, and the two ends of the top of the clamping plate mechanism are connected with the bottom ends of the two traction mechanisms correspondingly. The linkage type traction mechanisms are adopted, the two traction mechanisms can connect and support the two sides of the horizontal support, inclination of the horizontal support is avoided, and therefore inclination of the bridge body is reduced.

Description

technical field [0001] The invention belongs to the field of bridge hoisting equipment, in particular to a hoisting device for bridge construction and a method of using the same. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly. Bridges are generally composed of superstructure, substructure, supports and auxiliary structures. The superstructure is also called bridge span structure. Structure, the substructure includes the bridge abutment, the bridge pier and the foundation, the support is the force transmission device set at the support place of the bridge span structure and the bridge pier or the bridge abutment, and the auxiliary structures refer to the bridge head slab, conical slope protection, bank protection, diversion engineering Etc., bridge components need to be pre-installed on the ground during bridge maintenance and construction, and then the pre-assembled com...
