Abstract

The invention provides a car coupler automatic control system. The car coupler automatic control system comprises a main air pipe and an uncoupling pipeline; the main air pipe is divided into two paths; the first path comprises a first limiting switch connected with the main air pipe and a second limiting switch connected with the first limiting switch and communicated to a contact of a two-position five-way pneumatic control valve; the other path is communicated with an air inlet of the two-position five-way pneumatic control valve; the uncoupling pipeline is connected with a uncoupling cylinder; and a working port of the two-position five-way pneumatic control valve is connected with the pushing cylinder. According to the coupler automatic control system, under the single-coupler state, stretching out of the electrical coupler can be achieved through triggering of the first limiting switch, and retracting of the electrical coupler can be achieved through triggering of the second limiting switch.

Description

technical field [0001] The application belongs to the technical field of coupler connection, and in particular relates to a coupler automatic control system. Background technique [0002] With the development of rail transit technology, vehicles require more and more control functions. During the daily maintenance and overhaul of the coupler, it is often required to check the push-out and retraction functions of the electric coupler in the single-coupler state. The existing coupler automatic control system is mainly divided into a circuit control system and an air circuit control system. Due to factors such as electromagnetic interference in the circuit control system, it is easy to cause the coupler to malfunction, while the air circuit control system cannot perform daily maintenance and maintenance on the coupler in the single-coupler state. Maintenance work. [0003] Chinese patent application CN103863352A discloses a coupler automatic control system, including main air ...
