Abstract

The invention provides an anti-rolling device for electric locomotive in a shield tunnel. The device is arranged at the position, facing the end part of a rear wheel, of a motor base, above a track.the anti-rolling device comprises two brake assemblies and two telescopic assemblies, each telescopic assembly is fixed with the motor base of the tail part of the electric locomotive, each telescopic assembly includes a cylinder and a telescopic rod, The brake assembly is positioned directly above the two rail strips, and the telescopic rods of the two telescopic assemblies are respectively threaded in the two brake assemblies, and the telescopic rods are controlled to contract by the cab, and the brake assembly falls off the telescopic rods and onto the rail strips to brake the electric locomotive. As that anti-rolling device of the shield tunnel electric locomotive is simple in structure, economical and practical, convenient in installation and disassembly, the electric locomotive is safer to travel, the brake is quick and effective, and the electric locomotive roll injury accident is effectively avoided. The electric locomotive anti-rolling device of the shield tunnel electric locomotive is simple in structure, economical and practical, convenient in installation and disassembly.

Description

technical field [0001] The invention relates to the technical field of supporting equipment for shield tunneling construction, in particular to an anti-rolling device for electric locomotives in shield tunnels. Background technique [0002] The anti-rolling device of the electric locomotive in the shield tunnel is generally to install a hook on the head of the electric locomotive. When the car slides, the hook hooks the sleeper. Since the segments in the shield section are circular, arc sleepers or channel steel sleepers are used. In the case of the electric locomotive, the hook of the electric locomotive cannot effectively hook the sleeper, causing the electric locomotive to slip and hurt people. Contents of the invention [0003] In view of the above situation, the present invention provides an anti-rolling device for electric locomotives in shield tunnels, which solves the technical problems of limited use of existing anti-rolling devices, prone to rolling of electric l...
