Description

Technical Field

[0001] The utility model relates to the field of fully mechanized mining working face and chute mining and transportation in underground coal mines, in particular to a belt self-moving machine tail provided with a modular anchoring mechanism. Background Art

[0002] The self-propelled belt tail is the intermediate connection device between the bridge-type transfer machine and the belt conveyor of the chute transportation equipment, and is one of the important equipment for mine mining. Usually, after the working face has cut a piece of coal, the transfer machine needs to move forward one coal mining step along with the scraper conveyor under the push of the end bracket. However, in some mines, due to the need for matching with the working face, the forward movement of the transfer machine needs to use the self-propelled belt tail as the force point and move forward under the pulling action of the hydraulic cylinder of the self-propelled belt tail trolley. The weight of the self-propelled belt tail is generally lighter than the transfer machine, which often causes the transfer machine to not move and the self-propelled belt tail to be pulled back. Therefore, it is very important to develop a self-propelled belt tail with the function of anchoring itself. Summary of the Invention

[0003] The utility model aims to provide a belt self-moving tail provided with a modular anchoring mechanism, so as to solve the problem that the belt self-moving tail is pulled backward when the transfer machine moves forward.

[0009] One end of the right half snap ring and the left half snap ring on the half snap ring is clamped on the piston rod of the anchor hydraulic cylinder, and the other end is connected to the anchor seat through a fixing ring and a fastening bolt. The anchor seat can rotate 360 ​​degrees on the piston rod of the anchor hydraulic cylinder.
