Disconnectable busbar joint device of rigid contact network

Abstract

The invention provides a disconnectable busbar joint device of a rigid contact network, which belongs to the technical field of rail traffic and solves the technical problems that the conventional rigid contact network system is time-consuming and labor-consuming in operation, has low safety performance and the like when a flood gate or a civil air defense gate is required to be closed. The disconnectable busbar joint device of the rigid contact network comprises a busbar end A, a busbar end B and a connecting section between the busbar end A and the busbar end B, wherein the busbar end A and the busbar end B are connected with two ends of the connecting section respectively through a sliding busbar joint; the sliding busbar joint comprises a power supply arm bracket, a static joint and a moveable joint; the static joint is fixed on the power supply arm bracket; the moveable joint is arranged in the power supply arm bracket and can slide along the power supply arm bracket; the moveable joint is sleeved at the two ends of the connecting section respectively; the static joint is fixedly connected with the busbar end A and the busbar end B respectively; and a linkage device is arranged on the moveable joint. The disconnectable busbar joint device of the rigid contact network has the advantages of simplicity / labor saving in operation, safety in use and the like.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and relates to a disconnectable busbar joint device, in particular to a rigid catenary disconnectable busbar joint device used in tunnels. 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] In the construction of urban subway tunnels, civil air defense doors are designed, and anti-flooding doors are designed when the tunnel passes through the river. When the rigid suspension catenary encounters special situations of war and serious water leakage, it is necessary to quickly close the civil air defense doors and air ...

AI Technical Summary

Problems solved by technology

However, under the obstruction of the busbar, the civil air defense door and the anti-flooding door cannot be completely closed, and special personnel need to be sent into the tunnel to remove a section of the busbar at the civil air defense door and the anti-flooding door from the entire catenary system. When the situation is urgent or when there is a large amount of water, personnel cannot enter the tunnel. Even if they can enter the tunnel, disassembly is time-consuming and laborious due to existing design problems.
