Problems solved by technology

[0003] When installing traditional rail transit bidirectional converters, bolts are inserted into the mounting lugs on the outside of the bottom, and the entire device is fixed at the designated position by bolts. However, when bolts are used for installation, the thread will be damaged after a long time. Corrosion makes it difficult to disassemble, and secondly, it needs to turn multiple screws when installing and disassembling, which makes it more troublesome to use

Abstract

A rail transit bidirectional converter convenient to disassemble disclosed by the present invention comprises a bidirectional converter body, a plurality of mounting lugs are welded to the bottom of the outer wall of the bidirectional converter body, the bottom of the bidirectional converter body is movably connected with a mounting seat, and the bottom of the mounting seat is fixedly connected with a fixed seat. The top of the outer side of the fixing base is movably connected with a plurality of fixing nails. The bidirectional converter can be conveniently and directly placed in the mounting seat for mounting. After a connecting rod is shifted, a ratchet gear structure is only meshed with a second rack, a second gear is only meshed with the outer surface of a U-shaped toothed plate, at the moment, the U-shaped toothed plate can be independently pulled to reset, only the second gear rotates, at the moment, the bidirectional converter body can be separated from the interior of the device, and disassembly is convenient.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a rail transit bidirectional converter that is easy to disassemble. Background technique [0002] Compared with other modes of transportation, urban rail transit has the characteristics of safety, comfort, speed, large capacity, energy saving and environmental protection. However, with the expansion of the road network and the sharp increase in passenger traffic, the total energy consumption of urban rail transit has also increased significantly, and the serious problem of train braking energy waste has been paid more and more attention. Developed countries are actively discussing the utilization mode of braking energy, and successively proposed various methods such as resistance absorption, capacitor energy storage, inverter (including inverter to medium voltage and inverter to low voltage), bidirectional converter and so on. , In order to solve the absorption ...
