Automatic car coupler control system and application thereof

Abstract

The invention provides an automatic car coupler control system and the application of the automatic car coupler control system. The automatic car coupler control system comprises a main air pipeline, an uncoupling pipeline, an MRP main air valve, a UC uncoupling air valve, an electric coupler pushing air cylinder, an uncoupling air cylinder, a pneumatic control valve and a manual control electromagnetic valve. An air inlet of the pneumatic control valve is communicated with the main air pipeline. The auxiliary control end of the pneumatic control valve is communicated with the left end of the MRP main air valve. Two work ports of the pneumatic control valve are communicated with a front port and a rear port of the electric coupler pushing air cylinder respectively. The master control end of the pneumatic control valve is communicated with the uncoupling pipeline. The right end of the MRP main air valve is communicated with the main air pipeline. The UC uncoupling air valve is communicated with the uncoupling pipeline. The uncoupling air cylinder is communicated with the uncoupling pipeline. The uncoupling pipeline is communicated with an air outlet of the manual control electromagnetic valve. An air inlet of the manual control electromagnetic valve is communicated with the main air pipeline. According to the automatic car coupler control system and the application of the automatic car coupler control system, a car coupler can be automatically controlled through the simple structure and the assembling difficulty and the maintenance difficulty are reduced.

Description

technical field [0001] The invention belongs to the technical field of coupler connection for rail transit vehicles, and in particular relates to an automatic control system for a subway coupler and its application. Background technique [0002] In rail vehicles, the coupler is used to connect the carriages. If the coupler is uncoupled and connected manually, the workload is huge, the labor is dangerous, and the labor cost is high. Therefore, it needs to be improved to realize automatic control. Specifically, it is required to realize the automatic connection of the mechanical hook and the electric hook when the coupler is connected without manual operation; when the coupler is uncoupled, the decomposition of the electric hook and the mechanical hook can be completed after the driver presses the unhook button. [0003] In the prior art, domestic couplers already have control systems with similar functions. The invention patent with the publication number CN101698412A (couple...

Problems solved by technology

However, the structure of the control system in this patent is quite complicated, with many control units and many and lengthy compressed air pipelines, resulting in more components and high manufacturing costs (about twice as high), and because there are too many pipelines , and there are crossovers, the number of pipeline joints increases, and there are more intermediate links in the connection, which makes assembly and maintenance more difficult, and workers are prone to make mistakes during installation or assembly, so the cost of use is also higher

At the same time, because the technical scheme adopted in this patent has too many pipelines, more space is required for installation, which will not only bring about difficulties in installation, but also inevitably increase the difficulty in designing the coupler.

Especially in this patent, when the left end of the MRP valve fails, when the compressed air leading to the intake end of the two-position three-way valve V4 suddenly disappears, the electric hook will be forcibly retracted, which will cause the interruption of the train circuit and seriously affect the normal operation of the train.
