A cg-3 tunnel vertical arch trolley

Abstract

The invention belongs to the technical field of high-altitude operations, and particularly relates to a CG-3 tunnel arch abutment establishing vehicle. The vehicle comprises a vehicle frame, a chassiswalking system, a driving roof, an operation platform control system, main arm assemblies, hydraulic supporting legs, an operation platform and a hydraulic fixture assembly; three main arm assembliesare arranged on a front vehicle frame side by side, the main arm assemblies swing in four directions, rear supporting seats of the main arm assemblies are connected with the front vehicle frame, front supporting seats of the main arm assemblies are connected with the operation platform and the hydraulic fixture assembly, and dual triangular hydraulic horizontal moving mechanisms are installed onthe main arm assemblies; the hydraulic fixture assembly is composed of a fixture horizontal moving supporting arm, a horizontal moving pull rod oil cylinder and a clamping head, the fixture horizontalmoving supporting arm and the front end of the horizontal moving pull rod oil cylinder are connected with the clamping head, and a parallelogram mechanism is formed by the fixture horizontal moving supporting arm, the horizontal moving pull rod oil cylinder, the front supporting seats of the main arm assemblies and the clamping head.

Description

technical field [0001] The invention belongs to the technical field of high-altitude operation equipment, and in particular relates to a CG-3 tunnel vertical arch trolley. Background technique [0002] At present, the tunnel arching operation in our country is basically completed manually, and there is no available machinery. When artificial arching, the arch frame must be lifted and carried manually. A pair of arch frames is between 500-650kg, and each section is also Between 160-210kg, it is very laborious to carry and lift manually, and the labor intensity of personnel is high. In addition, artificial vertical arches employ a large number of people and all of them work under the working face. Once danger is found, the evacuation speed is slow, the risk factor is large, and the safety factor is small. If a vertical arch trolley is used to erect the arch, the handling and lifting of the arch frame depends entirely on the machine, and the personnel only operate the machine ...
