A kind of splint used in coal mining that is beneficial to reduce friction

Abstract

The invention discloses a splint for coal mine exploitation which is beneficial to reduce friction, which comprises a base, a bracket and a clamping block. A first fixing plate and a second fixing plate are installed on the base, and the first fixing plate is located on the second fixing plate. The inner side of the first fixed plate is provided with a push rod, the push rod is equipped with a rotating shaft, and the push rod is connected to the base and the movable plate through the rotating shaft, and the middle part of the movable plate is connected with a sleeve. The outer wall of the movable rod is connected with an elastic member, the base is connected with a first screw rod, the bracket is fixed above the second fixed plate, and the clamping block is connected to the bracket and the outer wall of the second screw rod , and the block is located above the movable rod. The splint is used in coal mine development that is conducive to reducing friction. The disassembly and installation of the cable is convenient, and it will not take too much time to install the splint. The fixing of the cable is relatively firm. The cable will not slide inside the device, causing the wire cable wear.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a splint for coal mining which is beneficial to reduce friction. Background technique [0002] The splint for coal mining is a device for fixing the cables of coal mining equipment during coal mining, so as to reduce the repeated friction of the cables on the ground during the operation of the machine and reduce the wear and tear of the cables. However, the existing coal mining There are the following problems with splints: [0003] 1. It is inconvenient to disassemble and install the cables. The cables used in coal mining machinery are usually very long, and multiple splints need to be installed, and the process of installing the splints will consume a lot of time; [0004] 2. The fixing of the cable is not firm enough, causing the cable to still move during the operation of the machine pair, causing the cable to rub against the ground and causing the cable to wear. [000...
