Upright chain connecting ring used for mine chain and capable of preventing self-locking during chain piling

Abstract

The invention discloses an upright chain connecting ring used for a mine chain and capable of preventing self-locking during chain piling. Self-locking can be prevented from occurring at the chain connecting ring by means of the upright chain connecting ring. The upright chain connecting ring comprises two half rings; the two half rings are in head-tail clamp fit to be assembled, a spring pin is hit into the assembled position of the two half rings, and thus the chain connecting ring is achieved by integrating the two half rings; a hollow chain connecting groove is formed in the inner side ofthe chain connecting ring; the chain connecting groove is buckled with a second chain ring body and a third chain ring body of the ends, needing to be connected, of two chain portions; and a clampingblock is mounted in the position, located between the second chain ring body and the third chain ring body, in the chain connecting groove, and the second chain ring body is separated from the third chain ring body through the clamping block. By means of the upright chain connecting ring, the cost can be greatly reduced, and disassembling is convenient. A main body of the chain connecting ring isnot changed, the middle space is large, and thus the chain portions of the two ends can be conveniently and easily mounted. During usage, the positions of the chain portions of the two ends are basically fixed, piled chain portions can be easily pulled apart even during chain piling, and thus phenomena like self-locking are avoided.

Description

technical field

[0001] The invention relates to the technical field of chain connection of transmission parts of an underground scraper conveyor in coal mines, in particular to a vertical link link for mining chains that prevents self-locking when stacking chains. Background technique

[0002] At present, there are mainly flat connecting links for mining round link chains, vertical connecting links for mining chains and flat connecting links for mining chains. The customer mainly chooses the model and type of the connecting link according to the type of chain used by the shearer and the usage habits. figure 1 The vertical one shown is a commonly used vertical link for mining chains, which is mainly composed of two half-rings 210 and spring pins 510 . The two half-rings are respectively connected to the second link 120 and the third link 130 at the two ends of the chain, and after being locked, the elastic spring pin 510 is embedded to make the combination firm and prevent d...
