Abstract

The invention provides a bus bar joint device of a subway tunnel. With the adoption of the bus bar joint device, the technical problem that a connecting segment of the existing bus bar joint device in the subway tunnel drops out and is unsmooth is solved. The bus bar joint device of the subway tunnel comprises a left bus bar segment, a right bus bar segment and the connecting segment arranged between the left bus bar segment and the right bus bar segment and used for connecting; the connecting segment can be detachably arranged between the left bus bar segment and the right bus bar segment; a flood gate is hinged on the inner wall of a tunnel body; and the connecting segment is on a gate closing track of the flood gate. The bus bar joint device of the subway tunnel has the advantages of saving time, and being high in efficiency, good in stability and safer in use and the like.

Description

technical field

[0001] The invention relates to a subway tunnel, in particular to a busbar joint mechanism of a subway tunnel. Background technique

[0002] With the rapid development of my country's urban rail transit construction, the form of rigid suspension catenary is widely used. Rigid suspension catenary is a system composed of catenary wires embedded in head-to-tail busbars. It is an important equipment for power supply of electrified railway locomotives and rail transit vehicles. Its quality directly affects the operation of locomotives.

[0003] Anti-flood doors are designed in the construction of urban subway tunnels. In the event of war and serious water leakage, it is necessary to quickly close the anti-flood doors and anti-flood doors of the tunnel to ensure the safety of the tunnel and personnel. However, under the blockage of the busbar, the anti-flood door cannot be completely closed, and special personnel need to be sent into the tunnel to remove a section...
