Detachable road steel bridge carrying erecting vehicle achieving low-position mounting and butt joint

Abstract

The invention provides a detachable road steel bridge carrying erecting vehicle achieving low-position mounting and butt joint. The detachable road steel bridge carrying erecting vehicle comprises a front lifting roll assembly, a vehicle body and a lifting plate assembly; the front lifting roll assembly is detachable, the position is adjustable, and two forks stretching across the vehicle body are mounted on the front side of the vehicle body in the horizontal direction; the lifting plate assembly is detachable, the position is adjustable, and the lifting plate assembly is mounted on the rear side of the vehicle body. Compared with the prior art, most of the components are of detachable structures, and no structure of an original forklift needs to be changed. Modular design is adopted, most of the components in the assemblies are commonly used, and maintenance security is easy. The structure of the erecting vehicle is adjustable, and super-low posture work can be completed. A detachable check ring replaces a guide roll, work flexibility is improved, the position of the check ring can be adjusted according to needs, and the check ring is suitable for cross beams of different specifications. After the front lifting roll assembly is additionally arranged on the vehicle body, labor intensity can be reduced, and the postures of a truss and other equipment can be guaranteed.

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 with low-level installation and docking. 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 i...

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
