Description

TECHNICAL FIELD

The forward movement of the traditional coal mining working face support completely relies on winch pulling, and the winch is used frequently and the labor intensity of workers is large, which not only wastes time, but also increases the risk of wire rope breakage of the winch. Therefore, it is of great significance to study the hydraulic support back-off equipment and back-off process of fully mechanized coal face to speed up the working face back-off speed.

[0003] The traditional hydraulic support back-off method mainly uses the cooperation of various devices to back off the hydraulic support. The shield frame is used to support the roadway roof during back-off, and then the winch is used to back off the hydraulic support to the designated position. After the arrangement of the shield frame is completed, the pulley device is fixed at the front end of the support, and then the steel wire rope is used for traction, and the winch is used to back off the hydraulic support to the designated position. During back-off, shield frames need to be arranged on both sides of the support to effectively avoid collision between the supports. When back-off, the support steering needs to be adjusted manually, and the dense wood pile and point column can be arranged to further improve the supporting strength.
