胶带机（Belt conveyor） Rules for the implementation of comprehensive protection devices for coal mine belt conveyors Coal mine safety regulations The 373rd rule: It adopts roller drive and belt conveyor When the machine is transported, it must be equipped with drive roller, anti-skid protection, coal loading protection and anti deviation device Degree protection, Smoke protection and automatic sprinkling device, The belt is a main transportation roadway transportation Machines must also be installed: Conveyor belt tensioning force lowering protector and anti tearing protector, Along the line Emergency stop protection device. I. installation Our coal mine belt conveyor comprehensive protection has the protection function: Scram protection, Anti Sliding protection, coal protection, anti deviation device, temperature protection, smoke protection, automatic sprinkler equipment Set, prevent tearing, protect, etc. The installation standards for various protections are as follows: (1) emergency stop protection device; The conveyor is on the side of the pedestrian, Starting at the nose, alternate intervals 50m Set up a two-way Drawstring Switch at loading point, pedestrian bridge, nose, tail 10m Should be within the scope of emergency Stop switch. (two) antiskid protection device; The utility model relates to an antiskid protection device for a driving roller, which is used for skidding friction between the driving roller and the conveyer belt When the belt conveyor automatically stop. One Inductive anti-skid protection device The magnet is mounted on the side of the driven roller, Install the speed sensor with the installation unit The magnet corresponds to the bracket. Two Roller type antiskid protection device The roller speed sensor is mounted on the upper surface of the lower adhesive tape or on the lower surface of the upper adhesive tape, And make glue Maintain sufficient driving friction with the rollers. (three) coal protection device; The function of the coal protecti
