Car coupler lifting device

Abstract

A car coupler lifting device comprises two lifting rod devices and further comprises an interlocking device, a U-shaped rod and a supporting piece, the middle of the U-shaped rod is connected with theinterlocking device through the supporting piece, and the two ends of the U-shaped rod are fixedly connected with the two lifting rod devices respectively. The U-shaped rod in the middle is connectedwith the lifting rod devices on the two sides to play a linkage role, and the interlocking device is connected with a car coupler ejector rod on a car coupler in a clamped mode. When a vehicle needsto be uncoupled, any one of the lifting rod devices on the two sides is rotated to a proper position, the lifting rod devices drive the interlocking device through the supporting piece so that the coupler ejector rod can rotate in a fan-shaped arc mode, and then the uncoupling action can be completed. According to the coupler lifting device, linkage can be achieved only by conducting operation onone side, and potential safety hazards caused when two machine heads of a decoupling hook operator operate in a penetrating and inserting mode are completely eradicated. The device is bilaterally symmetrical, simple in structure and rapid to install.

Description

technical field [0001] The invention relates to the field of rail locomotives, in particular to a coupler lifting device. Background technique [0002] The coupler is a vehicle component used to realize the connection between the locomotive and the vehicle or between the vehicle and the vehicle, transmit the traction force and the impact force, and keep a certain distance between the vehicles. According to the opening method, the coupler is divided into two types: upper action type and lower action type. The one that is opened by the lifting mechanism on the upper part of the coupler head is called the upper action type, and most trucks generally use this type; the one that is opened by means of the action of the push lever at the lower part of the coupler head is called the lower action type, and this type is usually used by passenger cars. The HXD3 series locomotives use the No. 13 down-acting coupler to connect the headstock and the carriage. The original design uses a s...

CN 201310639914.8 provides a locomotive coupler uncoupling device. In order to prevent the automatic uncoupling of the coupler due to the free jump of the lifting rod when the locomotive is running in a complex environment, it is mainly composed of a hook lifting rod and a cylinder device. It can only realize the unhooking action of the lifting rod on one side. Once the two heads are docked, the operator needs to intersperse between the two heads that are connected to realize the hooking operation of the two heads, which poses personal safety hazards.

CN201310536958.8 provides a kind of uncoupling device for railway vehicles, which is aimed at the automatic coupler of the knuckle tongue type, which is composed of a transmission mechanism and a locking and positioning mechanism. When the hook bar is on the other side of the vehicle, it needs to pass through the middle of the locomotive, which is dangerous
