Embodiment 1

[0029] see Figure 2-Figure 6 , the vertical link link for mining chains in this embodiment includes two half-rings 210, and the two half-rings are assembled end to end, and an elastic pin 510 is inserted into the assembly place so as to realize the assembly of the two half-rings 210 into one A link link, the inner side of the link link is provided with a hollow link slot 201, and the link slot 201 is respectively buckled and assembled with the second link 120 and the third link 130 of the two chains that need to be connected, so as to realize Connection of two chains.

[0030] A block 300 is installed on the part between the second link 120 and the third link 130 in the link slot 201 , and the block 300 separates the second link 120 and the third link 130 open, thereby avoiding the occurrence of figure 1 self-locking phenomenon.

[0031] Preferably, the block 300 includes a first limiting portion 310, a second limiting portion 320, and a connecting portion 330, and the fir...

Embodiment 2

[0035] see Figure 7-Figure 9 , because in actual use, the way of block interference fit in the first embodiment is still prone to loosening and falling off, which leads to self-locking phenomenon after falling off. The applicant has found through research that the main reason for the shedding is that the stress point at the second limiting ring 321 is very small, and the second limiting ring 321 is squeezed and then opened after assembly. Once the second limiting ring 321 If the opening is not in place, the clamping performance will be seriously affected. Moreover, although the connection part 330 adopts an interference fit, once the second limiting ring 321 is not in place, it will easily slide and fall off when the clamping block is pushed by the axial direction. This axial thrust may be the component force of the friction force exerted on the block when the second link and the third link are in contact with the block during use, and once the block is knocked in, it needs ...

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...
