Lower lockpin body, double-acting coupler and coupler buffering mechanism

Abstract

The invention discloses a lower lock pin body, which is used for being hinged between a lower lock pin and a lower lock pin hook of a coupler, and has uncoupling lever hanging holes so as to rotate around the lower lock pin hook under the action of the uncoupling lever hanging holes, wherein the end parts of both sides of the lower lock pin body are provided with the two uncoupling lever hanging holes respectively so that operating personnel can perform uncoupling operation on front and rear couplers of a connecting end between two vehicles at any side of a vehicle body. On the basis, the invention also provides a double-acting coupler with the lower lockpin body and a coupler buffer device, wherein the coupler buffer device also comprises two uncoupling levers and two uncoupling lever brackets; the uncoupling levers pass through keyhole-shaped through holes of the uncoupling lever brackets, and have limited sections at the matching positions; coupler head ends of the two uncoupling levers pass through the keyhole-shaped through holes of the two uncoupling lever brackets respectively and then are hooked with uncoupling lever hanging holes of the double-acting coupler; and clearances are reserved between the limited sections of the uncoupling levers and bar-shaped hole walls of the keyhole-shaped pylome.

Description

technical field [0001] The invention relates to the carriage connection technology of a rail vehicle, in particular to a lower lock pin body, a coupler acting on both sides and a coupler buffer device. Background technique [0002] The coupler is one of the important parts of the railway vehicle and has a standard connection profile; its main function is to ensure the connection between the vehicles and realize the operation of the train marshalling and traction vehicles. [0003] The existing railway couplers generally have three working states: locked, unlocked and fully open, that is, three states. When the coupler is in the locked state, the coupler lock iron blocks the knuckle and cannot be opened, and the vehicles in the connection will not be separated automatically; Lifting rod, through the lower lock pin body and the lower lock pin connected with the coupler lifting rod, lift the coupler lock iron upward to the unlocking position. The vehicle is separated; lift the...

Problems solved by technology

At this time, the front hook of the follow-up car is in the locked position. Therefore, it cannot be successfully linked with the follow-up car after it has slipped down, thereby reducing the success rate of marshalling and hanging, affecting the efficiency of marshalling operations; at the same time, it also affects the operation.
