Pulling rope switch PLR20-2D-G Pulling rope switch PLR20-2D-G Pulling rope switch PLR20-2D-G Conveyor PLR20-2D-G Pulling rope switch installation instructions: 1. PLR20-2D-G Pulling rope switches are installed in pairs on the left and right sides of the belt conveyor. Drill a 12mm hole on the iron frame next to the belt conveyor and tighten the pulling rope switch with M10 × 40mm bolts. 2. Install one drawstring switch every 40 meters, and its position should be lower than the belt and convenient for on-site workers to use. 3. The pull rope is tied to the first arm, and it is recommended to use plastic coated steel wire rope with a diameter of 3-5mm. The steel wire rope is fixed with a rope clamp, and a support ring is installed every 3 meters to prevent excessive sag of the steel wire rope and ensure reliable rope pulling action. Under the premise of ensuring normal operation of the switch, try to tighten the rope as much as possible to reduce the sag deflection of the steel wire rope. 4. For the climbing section of the belt conveyor, the distance between the pull rope switches and the length of the pull rope should be minimized as much as possible. 5. Wiring: The rope switch is equipped with a 1.2-meter-long four core rubber sleeve cable when it leaves the factory, and the core wire is equipped with wire numbers 1, 2, 3, and 4. Among them, 1 and 2 are normally open contacts that are alarm signals, and 3 and 4 are normally closed contacts that are shutdown signals. PLR20-2D-G Rope Switch Introduction: With the expansion of coal mine production scale and the improvement of production digitalization, the requirements for coal mine safety production are also constantly increasing. As a belt conveyor for coal mine production and transportation equipment, its safe and reliable operation is very important. This article takes common faults of mining belt conveyors as the research object. In response to the current problems of incomplete protection types and low reliability of mining belt conveyors, combined with microcontroller and sensor technology, the protection system of the belt conveyor is designed. The mechanism of common faults such as slipping, overheating, deviation, coal stacking, smoke, etc. of the belt conveyor is studied, and a feasible sensor detection method is designed. Through the microcontroller, the belt conveyor fault is alarmed and the belt conveyor shutdown and related protection device actions are controlled.
