Movable multi-track fork and working method thereof

Abstract

The movable multi-track turnout comprises a front-end guide rail, a turnout and a rear-end guide rail which are arranged in sequence, and the front-end guide rail, the turnout and the rear-end guide rail are installed on a first wear-resisting steel plate, a second wear-resisting steel plate and a third wear-resisting steel plate correspondingly. The first wear-resistant steel plate, the second wear-resistant steel plate and the third wear-resistant steel plate are all mounted on a tunnel track; guide rollers are arranged at the bottoms of the first wear-resistant steel plate, the second wear-resistant steel plate and the third wear-resistant steel plate, and the guide rollers and the tunnel track are arranged in a relative rolling manner; the first wear-resistant steel plate and the second wear-resistant steel plate as well as the second wear-resistant steel plate and the third wear-resistant steel plate are connected through hinge connectors; the front end of the front-end guide rail and the rear end of the rear-end guide rail are each of a slope structure, the wedge-shaped structure of the rear end of the front-end guide rail is attached to the wedge-shaped structure of the front end of the turnout, and the wedge-shaped structure of the front end of the rear-end guide rail is attached to the wedge-shaped structure of the rear end of the turnout. The method has the advantage that the problem of wrong rail transport vehicles in the long-distance tunnel can be solved.

Description

technical field [0001] The invention relates to the technical field of subway tunnel construction, in particular to a movable multi-track switch and a working method thereof. Background technique [0002] The turnout is a staggering device used for the entry and exit of multiple trains of rail transport vehicles for muck transportation during tunnel construction. At present, it is mainly in the form of fixed turnouts, and most of them are located at the platform or tunnel entrance. When the tunnel is constructed over a long distance, the fixed The turnout is far away from the excavation work face, and it takes a long time for the rail transport vehicle driving out to reach the fixed turnout position, and it will take a long time to arrive at the wrong vehicle after passing the incoming rail transport vehicle. On the working face, during the period of driving in and out, the excavation work of the muck work of the tunnel must be stopped, which seriously affects the constructi...

Problems solved by technology

[0002] The turnout is a staggering device used for the entry and exit of multiple trains of rail transport vehicles for muck transportation during tunnel construction. At present, it is mainly in the form of fixed turnouts, and most of them are located at the platform or tunnel entrance. When the tunnel is constructed over a long distance, the fixed The turnout is far away from the excavation work face, and it takes a long time for the rail transport vehicle driving out to reach the fixed turnout position, and it will take a long time to arrive at the wrong vehicle after passing the incoming rail transport vehicle. On the working face, during the period of driving in and out, the excavation of the muck work of the tunnel must be stopped, which seriously affects the construction efficiency and construction progress.

[0003] Even if the distance between the fixed turnout and the tunnel working face is adjusted in time during construction, the work of dismantling and splicing the track will waste a long time, seriously affecting the progress of the construction period. This is a common problem in excavating tunnels by rail trains
