Steel ring mounting machine for tunnel construction

Abstract

The invention relates to a steel ring mounting machine for tunnel construction. The steel ring mounting machine comprises a chassis supporting mechanism, a chassis moving mechanism, a chassis rotating mechanism, a large arm, a small arm and a bucket rod mechanism. The chassis supporting mechanism is fixedly connected to an operation rack, the chassis moving mechanism is arranged on the chassis supporting mechanism, the chassis rotating mechanism is arranged on the chassis moving mechanism, the chassis rotating mechanism is hinged to the large arm, the large arm is hinged to the small arm, the small arm is hinged to the bucket rod mechanism, a large arm oil cylinder is hinged between the chassis rotating mechanism and the upper end of the large arm, a small arm oil cylinder is hinged between the large arm and the small arm, and a bucket rod oil cylinder is hinged between the small arm and the bucket rod mechanism. The steel ring mounting machine is reliable in mounting quality and high in operation efficiency, can adapt to the environment and requirement of the tunnel construction in our country well, and has high practical value in the tunnel construction field.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to a mechanical installation device for grasping, lifting and adjusting attitude of a steel ring during tunnel construction. Background technique [0002] In recent years, with the rapid development of my country's economy and the continuous acceleration of urbanization, the construction of urban rail transit is also developing rapidly, and will become an important pillar of urban public transportation. With the extension of the subway mileage and the increase of the number of years of operation, the safety of the subway tunnel structure becomes more and more important. Due to geological conditions and long-term vibration and normal loss of train operation, subway tunnels often have tunnel deformation, segment penetration through cracks, local water leakage in the tunnel, and segment settlement exceeding the normal monitoring control value. Therefore, for the daily maintenance of ...

AI Technical Summary

Problems solved by technology

During the maintenance process, due to the narrow construction space and the difficulty in accurate positioning and installation of heavy steel plate components, a series of problems have been brought to the quality and safety of tunnel segment reinforcement.

At present, the maintenance of subway tunnels in China mainly uses manual installation of steel rings to increase the stability and sealing of tunnel segments. This installation method requires many construction personnel, high labor intensity, low operation efficiency, low installation quality, and dangerous construction more sexual

The introduction of foreign steel ring installation machines is not only expensive, but also cannot be well adapted to the environment and requirements of tunnel construction in my country
