Abstract

The invention provides a tunnel expanding machine. The machine comprises a bottom plate, through grooves are formed in the four corners of the top of the bottom plate, elastic moving mechanisms facilitating equipment moving are fixedly installed in the through grooves in the top of the bottom plate, an installation box is fixedly installed at the top of the bottom plate, handrails and jacking mechanisms facilitating supporting are symmetrically and fixedly installed on the two sides of the installation box, the jacking mechanisms are fixedly mounted in the installation box, top plates are fixedly mounted at the output ends of the jacking mechanisms, connecting plates and adjusting mechanisms are fixedly mounted at the tops of the top plates, the adjusting mechanisms are fixedly mounted atthe bottom of the installation box, and the output ends of the adjusting mechanisms are matched with the jacking mechanisms. The tunnel expanding machine is simple in structure and convenient to operate, the top of a tunnel can be conveniently supported through mutual cooperation of the jacking mechanisms and the adjusting mechanisms, meanwhile, the elastic moving mechanisms are arranged on the tunnel expanding machine, the tunnel expanding machine can be moved and used conveniently, and the tunnel expanding machine is high in practicability.

Description

technical field [0001] The invention relates to the technical field of tunnel diameter expansion, in particular to a tunnel diameter expansion machine. Background technique [0002] A tunnel is an engineering building buried in the ground, and it is a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mine tunnels, and military tunnels. The structure of the tunnel includes two parts: the main building and the auxiliary equipment. The main building is composed of the tunnel body and the tunnel door, and the auxiliary equipment includes car avoidance tunnels, fire-fighting facilities, emergency communication and waterproof and drainage facilities, and the long tunnel also has special ventilation and lighting equipment. [0003] In the process of maintenance and construction of some municipal sewers, it is necessary to support the inner wall to prevent collapse when it is not built, which is not conducive ...
