Installation structure of a disc-type electric cabinet for a low-floor vehicle

Abstract

The invention discloses a mounting structure of a disc-type electric cabinet for a low-floor vehicle and belongs to the technical field of rail transit mounting. The electric cabinet is mounted in a transition area between a vehicle roof and a vehicle window. Various electrical devices are mounted on the structure. A cabinet body of the electric cabinet comprises a plurality of sealed tubular cavity structures, and the multiple sealed tubular cavity structures are axially connected through a splicing plate and then form a long and narrow tubular cavity structure stretching across the window area of a vehicle body. The upper portion of the long and narrow tubular cavity structure is provided with a bending part, the bending part is connected with the vehicle roof through bolt fasteners, and the lower portion of the long and narrow tubular cavity structure is connected with a vehicle body stand column through a support. According to the mounting structure of the electric cabinet, residual space of the vehicle roof of the low-floor vehicle is effectively used, the mounting structure is well linked with an external maintenance interface, and equipment mounting and equipment maintenance are facilitated due to reasonable longitudinal-depth arrangement.

Description

technical field [0001] The invention relates to an electrical cabinet for low-floor vehicles, belonging to the technical field of rail transit installation. Background technique [0002] Modern tram vehicles, unlike subway projects, do not have electrical cabinets at the end of the vehicles. Therefore, the electrical equipment on the vehicle can only use other spaces for installation and wiring harness laying, usually in the window area. [0003] However, at present, there are a lot of vehicle equipment, and the equipment itself is heavy, and the window area of ​​the vehicle is large, resulting in a small space in the window area and no installation points. Small size and difficult equipment maintenance, so how to reliably install the electrical cabinet and interior cover panels on the car body becomes very difficult. Contents of the invention [0004] Aiming at the above technical problems, the present invention proposes a new electrical installation cabinet structure, ...
