Do you Know About the Installation and Adjustment of the Pull Cord Switch on the Belt Conveyor?

Do you know about the installation and adjustment of the Pull Cord Switch on the belt conveyor?
Pull Cord Switch is commonly known as "emergency stop switch". When the belt conveyor need downtime, Pull Cord switch action will stop the conveyor. Pull Cord Switch can be divided into manual reset and automatic reset. Automatic reset: after action, it can automatically return to the initial position, may lead to error start. Manual reset: after action, the self-locking device can maintain the operating position, it need to manually reset handle to make its return to the initial position.
Pull Cord Switch should be installed on both sides of the conveyor where has a maintenance channel, installation position should ensure that the maintenance person operates conveniently in the event of an emergency.
1.Pull Cord Switch is fixed on the rack.
2.The distance of the two switches on one side is about 50 m, the two switches are connected by the diameter 4mm of wirerope, elastic should be moderate.
3.To reduce the influence of the weight of wire rope on switches, we install supporting ring on the frame every 3 m to support the steel wire rope.
4.The other end of the rope is in tension spring (with rope buckle), In a way not affecting the normal use, using tightener to pull the rope tension on both sides, and to ensure that tension is balanced on both sides.
(Note: The climbing section of the conveyor, should try to shorten the Switch spacing distance and the pull rope length.)

Why will Belt Conveyor Pulley Wear?

Belt conveyor is a kind of common conveyor equipment, often used in a variety of material transportation with large throughput, stable performance. In the process of using, pulley may occur wearing, this phenomenon is caused by two reasons:
One reason is that the design gap between roller bracket and pulley is too small, at the same time, building foundation hole vertical distance is less than the pulley support distance.In the process of belt running, overlarge belt tension will result in the change of its traction.Return accretion has not been cleared up, which will form accumulation debris and occur rubber friction.For design factors,as the space between pulley stents and pulley is too small, and the base hole of the vertical distance is less than the pulley support distance, it is not easy to handle timely, which is the main cause of pulley rubber lining wear.
Work environment factor is the second reason leads to rubber lining equipment damage phenomenon.

Daily, Weekly, Monthly Belt Conveyor Check&Maintenance Work

When using the belt conveyor, less daily check and maintenance or do not pay attention to maintenance will greatly reduce the service life of the belt conveyor, when the belt conveyor problems occur, it will affect the work efficiency, so regular inspection for belt conveyor parts is needed.
Daily check
Mechanical items: inspect the guardrail, bridge, roller, pulley, turnabout pulley and belt.
Electrical items: inspect the anti-skid device, deviation switch, emergency stop switch, tear detection device, anti-reverse device.
pull switch

Weekly check
Mechanical items: inspect the driving wheel, guide wheel section, reducer, inspect the machine's tail, check tensioning device and pull rope device.
Electrical items: inspect the main motor, inverter, filter, repair and inspect the main transformer wiring, electrical control, power system.
Monthly check
Mechanical items: inspect the rope wheel, transition wheel, guide wheel, driving wheel, belt wheel, tensioning car and check the oiling.
Electrical items: inspect the fastening bolts, fast switch; the maintenance and repair of commutator, limit protection, emergency stop protection and the alarm system.
