Wagon coupler unlocking mechanism and wagon coupler buffer device with the same

Abstract

The invention provides a wagon coupler unlocking mechanism which comprises the components of a coupler release rod, a release rod base, a supporting base and a coupler release chain. The coupler release rod is arranged on the release rod base and the supporting base and can freely rotate relative to the release rod base and the supporting base. One end of the coupler release chain is rotatably connected with the end of the coupler release rod, and the other end is rotatably connected with a rotating shaft on the wagon coupler. Through rotating the coupler release rod, the coupler release chain is tightened and the rotating shaft on the wagon coupler is driven to rotate, a lock iron block in a wagon coupler chamber is lifted and the wagon lock is in an unlocked state. After the coupler release rod is placed down, the lock iron block falls by means of self weight, and the rotating shaft returns to a locked state, thereby finishing a whole wagon hook unlocking process. The wagon coupler unlocking mechanism has advantages of simple and reliable structure and convenient detachment. The wagon coupler unlocking mechanism can totally satisfy the general requirement and interchange requirement of a railway wagon coupler buffer device in the Commonwealth of the Independent States (CIS), European countries and some African countries. Furthermore wagon utilization efficiency is improved.

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...

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
