Installation and wiring:
1. The rope switch is installed in pairs on the left and right sides of the tape machine. The intermediate frame of the mounting bracket and the tape machine is fixed by bolts or by welding. The position should be lower than the tape and convenient for the on-site staff. It is advisable to have a distance of about 50m between the two rope switches.
2, the rope is recommended to use plastic coated steel wire rope, (or ordinary steel wire rope 1XW19-4 (5)-150, wire diameter 4-5mm can be). The wire rope is fixed with a rope card (6KTH), and a bracket is installed every 3m to avoid excessive winding of the wire rope and ensure reliable operation of the rope. Under the premise of satisfying the normal operation of the switch, tighten the rope as much as possible to reduce the sag of the wire rope.
3. For the climbing belt conveyor, the switch spacing and the length of the rope should be shortened as much as possible.
4. Wiring: The drawstring switch is equipped with a 1.2m four-core rubber cable at the factory. The core wire is equipped with 1, 2, 3, and 4 wire numbers, of which 1, 2 are normally open contacts, and 3 and 4 are normally closed. contact.
