Problems solved by technology

[0006] (1) The above two technologies only improve the efficiency and cost of daily construction and maintenance operations, and cannot meet the needs of rapid repair operations and minimize the impact on operations
[0007] (2) The scope of application is small, and the requirements for the on-site environment are high. Generally, if the tunnel has no special design, there is no reserved channel, and it is not suitable for installing this kind of suspension device in the tunnel without reserved channel.

Abstract

The invention discloses an urban rail transit rigid contact network suspension rapid repair device, which comprises a supporting device and a positioning device. The supporting device comprises a suspension base and a fixing bolt, and the fixing bolt fixes the suspension base in a shield piece located on the top of a subway tunnel. The positioning device comprises a bus bar positioning wire clamp, a pin insulator, a B-type channel steel base and a T-shaped bolt, and is used for bearing the vertical load and the horizontal load of a suspension point. The urban rail transit rigid contact network suspension rapid repair device is simple in structure and high in adaptability, and the functions of rapid disassembly and assembly and rapid repair of the contact network can be achieved.

Description

technical field [0001] The invention relates to the catenary technology of the urban rail transit power supply system, in particular to a rapid repair device for the rigid catenary suspension of the urban rail transit. Background technique [0002] The urban rail transit system, especially the subway, has made a great contribution to alleviating the pressure of ground transportation for urban travel. Its main power source is electric energy. Since the subway vehicle itself does not have energy storage equipment, it is necessary to set up a complete functional system along the subway line to supply power to the subway vehicles. The catenary is the final energy supply line of the subway, and the rigid catenary can be very good. It meets the requirements of low-clearance tunnels, has the characteristics of no tension in the catenary wire, and low failure rate, so it has been widely used. The existing rigid catenary is generally erected in the tunnel through the suspension devic...
