A coupler unlocking mechanism and a coupler buffer device having the unlocking mechanism

Abstract

The invention provides a coupler unlocking mechanism, which includes a hook lifting rod, a lifting rod seat, a support seat and a hook lifting chain. Free rotation, one end of the hook lift chain is rotatably connected to the end of the hook lift rod, and the other end is rotatably connected to the rotation shaft on the coupler. By turning the hook lift rod, the hook lift chain is stretched straight and drives the rotation shaft on the coupler to rotate , lift the lock iron in the coupler hook cavity, the coupler is in the unlocked state, when the hook handle is put down, the lock iron falls by its own weight, the rotating shaft returns to the initial position, the coupler returns to the locked state, and the entire coupler unlocking process is completed. The invention has the characteristics of simple and reliable structure and convenient disassembly, can fully meet the general requirements and interchange requirements of the coupler buffer devices of railway wagons in CIS, Europe and some African countries, and improve the operation efficiency of vehicles.

Description

technical field [0001] The invention belongs to the technical field of railway traffic, in particular to a coupler unlocking mechanism and a coupler buffer device with the unlocking mechanism. Background technique [0002] Coupler buffer device is an important part of railway rolling stock. Due to certain differences in policies, regulations and technical standards of various countries, factors affecting the selection of coupler buffer devices such as railway wagon marshalling methods, running speeds, line conditions, and buffer capabilities are different, resulting in differences in the configuration of parts of the coupler buffer devices. Unavoidable differences exist in opening methods and installation structures. [0003] It is well known in the art that the railway vehicles of most countries in the world, including China, adopt the upper-acting or lower-acting couplers that meet the AAR standard. The upper-acting coupler; the coupler that is unlocked and unlocked by m...

AI Technical Summary

Problems solved by technology

In the Commonwealth of Independent States, Europe and some countries in Africa, couplers similar to the ГОСТ standard are used, and their opening methods are completely different from the above two forms, so that the existing coupler buffer devices in my country cannot be used interchangeably with them, let alone with local existing trucks even hanging
