Detachable highway steel bridge carrying and erecting vehicle for cross beam installation

Abstract

The invention provides a detachable highway steel bridge carrying and erecting vehicle for cross beam installation. The detachable highway steel bridge carrying and erecting vehicle comprises laterally arranged lifting roller components, a vehicle body and a lifting plate component. The two laterally arranged lifting roller components are detachable, are adjustable in position and are installed on two forks of the vehicle body in the longitudinal directions respectively and installed on two sides of the vehicle body. The lifting plate component is detachable, is adjustable in position and is installed on the rear side of the vehicle body. Compared with the prior art, most of the components are of detachable structures, and any structure of an original forklift is not needed to be changed. Most of members in the components are universal and are easy to maintain and ensure. The erecting vehicle is adjustable in structure and can complete ultralow-posture operation. Guiding rollers are replaced by detachable retainer rings, the operating flexibility is improved, and the retainer rings can be adjusted in position as required and can be suitable for different specifications and sizes of cross beams. A front-arranged lifting roller component is added to the vehicle body, the labor intensity can be reduced, and the postures of devices such as trusses can be also ensured.

Description

technical field [0001] The invention belongs to the technical field of engineering operation equipment, and in particular relates to a detachable highway steel bridge transporting and erecting vehicle installed with beams. Background technique [0002] Prefabricated highway steel bridges, as one of the war preparation materials reserved by the Ministry of Communications on behalf of the country, have been widely used for decades, whether in wartime highway bridge repairs and rush construction, overcoming river obstacles, or in peacetime earthquake and flood rescue and disaster relief , traffic security are playing an irreplaceable role. [0003] During the erection process of the prefabricated highway steel bridge, it is necessary to rely on manpower to move the trusses, beams, etc. to the transport and erection vehicle, and then carry out docking. There are currently two types of auxiliary erection equipment for prefabricated highway steel bridges. One is propulsion equipm...

AI Technical Summary

Problems solved by technology

There are currently two types of auxiliary erection equipment for prefabricated highway steel bridges. One is propulsion equipment, such as flat rolls, rockers, lower string joints, and inclined chords, and the other is installation tools, such as wrenches, crowbars, and mallets. etc., but none of these devices can realize the handling and erection of trusses and beams

[0004] Although the existing transport and erection equipment (vehicles) can carry and erect trusses and beams, most of the existing transport and erection equipment (vehicles) are integrally non-detachable, and their positions are fixed and invariable. The lifting of the hydraulic oil pipe of the auxiliary operation equipment is adjusted, and the equipment itself cannot be adjusted, so it is difficult to carry items of different specifications; considering the complex and changeable operation area, sometimes the height of the truss may be close to the height of the upper surface of the forklift, and it will not be possible to operate at this time, and it will not be possible to achieve super Low-level operation; due to the excessive friction between the surface of the shelf and the truss, the movement is laborious, which affects the efficiency of the truss docking
