The bi-directional rope switch PJZS-3145S/2 for the conveying industry is composed of a pull rod, a reset handle, a cam, a locking groove, and a micro switch. The pull rope switch is installed on the frames on both sides of the belt conveyor, and is connected along both sides of the conveyor with a steel wire rope. When an emergency occurs in the conveyor belt equipment, the steel wire rope is pulled at any location along the site, and the steel wire rope drives the drive arm to rotate. The precision cam is displaced by the torque spring driven by the transmission shaft, and the micro switch is driven to cut off the control line, causing the conveyor to stop running. The installation and adjustment rope switch should be installed in a location with maintenance channels on both sides of the conveyor, and the installation position should ensure that maintenance personnel can operate conveniently in emergency situations. 1. Fix the rope switch on the rack. 2. The distance between the two switches on one side is about 50m, using a diameter ofΦ The steel wire rope connection of 4 should have moderate elasticity. 3. To reduce the impact of the weight of the steel wire rope on the start of the switch, a support ring is installed on the frame every 3 meters to support the steel wire rope. 4. The other end of the steel wire rope is tied to the tension spring (fixed with a rope buckle), and the tension on both sides of the rope is tightened using a tightener without affecting normal use, ensuring that the tension on both sides is balanced. (Note: For the climbing section conveyor, the switch spacing and rope length should be minimized as much as possible.) Precautions: 1. Cut off the main power supply first, and then use a multimeter to measure the live wire. The switch must be installed at one end of the live wire. 2. Cut the live wire in a suitable place, and there are two joints, and the pull switch also has two joints. 3. Peel off the two joints of the live wire and expose the metal wire, and connect them to either of the two joints of the switch. 4. Cut off the excessively long metal wire at the connected joint to prevent two metal wires from colliding and short circuiting. 5. Loosen the cover of the pull switch and you can see a metal shaft with a hole at one end. 6. There is also a hole on the side of the plastic casing of the pull switch. First, pass the pull wire through the opening of the plastic casing to introduce the pull wire into the pull switch. Then, insert one end of the introduced pull wire into the shaft and tie a knot. Shorten the excessively long pull wire after tying. 7. Rotate the cover of the cable switch to prevent electric shock. Technical parameters 1. Environmental conditions for use a.
