Bridge big-height lifting displacement equipment based on vehicle set and construction method thereof

Abstract

The invention discloses bridge big-height lifting displacement equipment based on a vehicle set and a construction method thereof. The equipment comprises the vehicle set and a lifting transfer support module; the vehicle set is arranged at the lower part of the lifting transfer support module; the lifting transfer support module comprises at least two rows of conversion connecting beams longitudinally arranged; multiple beam lower outer stand columns, vertically arranged in parallel, are fixedly mounted at the lower parts of each row of the conversion connecting beams; multiple beam lower inner stand columns, corresponding to the beam lower outer stand columns, are arranged on the inner sides of the beam lower outer stand columns; the tops of the beam lower inner stand columns are fixedlyconnected with the bottoms of the conversion connecting beams; the bottoms of the beam lower inner stand columns are fixedly connected with the vehicle set; multiple beam upper support stand columns,vertically arranged in parallel, are fixedly mounted at the upper parts of the conversion connecting beams; upper distribution beams are fixedly mounted on the beam upper support stand columns; and connecting brackets for supporting beam bodies are arranged on the distribution beams. The equipment is simple in lifting displacement structure and convenient to assemble, and can realize quick disassembly, replacement and shifting of big-clearance bridges (groups).

Description

technical field [0001] The invention relates to the technical field of bridge lifting, shifting, dismantling, installation and construction, in particular to a large-height lifting and shifting equipment for bridges based on train groups and a construction method thereof. Background technique [0002] With the improvement of people's living standards in our country and the acceleration of road construction and urbanization, some cities and road bridges have problems such as unsatisfactory planning, insufficient traffic capacity, insufficient carrying capacity, and insufficient bridge clearance. Most of them need to be demolished, replaced or When performing the above operations, especially for bridges with large headroom and large tonnage, the prior art has the following deficiencies: [0003] (1) When demolishing bridges, it is difficult to directly dismantle bridges with a large clearance (more than 6m), especially bridges that cannot be demolished by blasting. For exampl...

AI Technical Summary

Problems solved by technology

[0003] (1) When demolishing bridges, it is difficult to directly dismantle bridges with a large clearance (more than 6m), especially bridges that cannot be demolished by blasting. For example, the existing lifting and lowering demolition method based on continuous lifting oil cylinder is difficult to construct, requires a large bridge side work space, and is not universal. The existing jack-based bridge lifting and lowering demolition method has low work efficiency and poor safety;

[0004] (2) During the construction of the bridge, affected by the load limit, height limit and width limit of road transportation, especially the beam body based on industrialized prefabrication with large tonnage or large clearance is difficult to transport and install on the road, the existing technology can only adopt the method of transport and hoisting in pieces Construction, on-site operation workload is heavy, the construction period is long, and safety and quality are difficult to guarantee;

[0005] (3) When the bridge is displaced, the existing jacking and hoisting technology can only move vertically, the pushing technology is complicated and can only move horizontally, and the swivel technology is very complicated and can only rotate limitedly. Bridges with large clearance and rapid multi-directional displacement have poor adaptability, and the economic efficiency of combined use is very poor
