摘要： A coupler uncoupling control mechanism is provided in the present application, comprising an uncoupling cylinder, a propelling cylinder and a control assembly, wherein the propelling cylinder is connected to a first valve body, and the first valve body comprises a first air inlet connected to the main reservoir pipe of the train, a first air outlet communicated with the first air inlet, a second air inlet and a second air outlet communicated with the second air inlet; the first air outlet is communicated with the air inlet chamber of the propelling cylinder, and the second air inlet is communicated with the air outlet chamber of the propelling cylinder. The control assembly comprises a second valve body and the second valve body is a pneumatic control valve; the second valve body comprises a third air inlet communicated with the uncoupling pipe of the train, a third air outlet communicated with the third air inlet, and a first control port capable of controlling airflow communication between the third air inlet and the third air outlet after being triggered; and, the third air inlet is communicated with the air inlet of the uncoupling cylinder, and the first control port is connected to the first air outlet of the first valve body. The present application can ensure that electrical couplers are uncoupled successfully.
