Problems solved by technology
At present, the pneumatic control unit of the existing coupler control system usually uses two single air-controlled two-position five-way valves to control the exhaust and intake air at the front and rear ends of the push cylinder, and one end of the single air-controlled two-position five-way valve is controlled by air pressure , the other end uses a spring to reset, this coupler control system tends to make the push cylinder run unstable, resulting in unstable extension and retraction of the electric coupler

The invention provides an automatic control system for a car coupler. The system comprises an uncoupling air cylinder, a pushing air cylinder and a main air pipe connector. as well as a first double-pneumatic-control two-position five-way valve connected with the rear end of the main air pipe connector, and a second double-pneumatic-control two-position five-way valve connected with the front end of the main air pipe connector. Two first working ports of the first double-pneumatic-control two-position five-way valve are connected with a front end connector and a rear end connector of the pushing air cylinder respectively. Two second working ports of the second double-pneumatic-control two-position five-way valve are respectively connected with the unhooking air pipe and the first main control end. The pressure difference between the two control ends of the first double-pneumatic-control two-position five-way valve is controlled through the pressure difference between the two control ends of the second double-pneumatic-control two-position five-way valve, then the valve direction of the first double-pneumatic-control two-position five-way valve is controlled, inflation and deflation of the front end or the rear end of the pushing air cylinder are achieved, and then the electric car coupler is controlled to stretch out and retract back.
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] In the automatic coupling and slowing devices in EMUs, urban rail and subway vehicles, the electric coupler matched with the push system has become a standard configuration. With the automatic coupling and uncoupling of the mechanical coupler, the coupling and uncoupling of the electrical coupler occurs, and then Realize the automatic connection and separation of the electrical lines of two train sets. At present, the pneumatic control unit of the existing coupler control system usually uses two single air-controlled two-position five-way valves to control the exhaust and intake air at the front and rear ends of the push cylinder, and one end of the single air-controlled two-position five-way valve is controlled by air pressure , the other end utilizes the spring to reset, and this coupler...
