Tire type tunnel track laying crane and construction method

Abstract

The invention discloses a tire type tunnel track laying crane and a construction method. The crane comprises wheel groups, a gantry, a working platform and a lifting device, wherein the wheel groups are arranged around the bottom of the gantry respectively; the working platform comprises a console, a power supply device and a hydraulic device; the console and the power supply device are respectively mounted on one wheel group; the hydraulic device is fixedly mounted on the gantry; the lifting device comprises a lifting appliance and a winch; the winch is fastened on the gantry and is linked with the lifting appliance through a steel wire rope. The construction method comprises the following steps: carrying out preparation before construction, constructing a shield tunnel, and carrying outtransferring operation. By adopting the tire type tunnel track laying crane, the technical problems that the prior art is only applicable to a single cross section size, tube pieces are greatly damaged if a track is temporarily laid in a tunnel, and the construction efficiency is low, can be solved, a whole-process tire type walking mode is achieved, construction of different cross sections such as tunnels, platforms and defense doors in tunnels can be achieved, construction steps can be simplified, the working and production efficiency can be improved, and damage of temporary tracks to tube sheets can be also reduced.

Description

technical field [0001] The invention relates to a crane and a construction method, belonging to the field of engineering equipment, in particular to a tire-type tunnel track-laying crane and a construction method. Background technique [0002] At present, the construction of various types of subway track-laying gantry cranes generally adopts the whole process of laying temporary running tracks with different gauges. First, the bottom plate of the steel pier is fixed on the platform and the bottom plate of the tunnel with expansion bolts, and the height of the steel pier is adjusted to the construction requirements. position, the upper plate of the steel pier is fastened to the bottom plate of the rail with bolts, the track-laying gantry cranes operate in pairs, and the construction work is carried out on the temporary track in the way of lifting the rail. The segments will be destroyed during the above construction, laying and dismantling the temporary track will endanger th...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a tire-type tunnel track-laying crane and a construction method to solve the technical problems that the existing technology can only adapt to a single section size, and laying temporary rails in the tunnel will cause great damage to the segments and low construction efficiency. The whole tire-type running mode can realize the construction of different sections in the tunnel including tunnels, platforms, civil air defense doors, etc., simplify the construction steps, improve the production efficiency of the operation, and reduce the damage caused by the temporary rail to the segments
