1. Features of Backstop for Belt Conveyor
A) Easy Installation & Disassembling:
Quick disconnect mounting pins for fast torque arm installation and removal
B) Reliable Lubrication:
a. Unique sealing design: Using dual lipped seals and ring to seal. Dual lipped seals can effectively avoid internal oil leakage. Dust ring can prevent outside dust from contacting oil seal to provide prolonged life in hostile environments.
b. Thorough system design: Inner cam can rotate freely with shaft. Contact-sealed splash circulation can lubricate and protect work piece and minimize wear and tear. Multiple oil drain plug can ensure the installation of backstop be mounted at any desired angle. Filtered breather, oil sight gauge and purgeable grease-cavities provide a complete self-lubricating system, which shortens maintenance time.
C) Longer Service Life:
Unique design of cylindrical rollers and wedge action weaken the backstopping contact stress, which increase life.
2. Application of backstop for belt conveyor
The Backstops for belt conveyor are extensively used in inclined belt conveyor, bucket elevators and etc. to arrest the rolling back of the machine in case of power off or sudden stoppage of the equipment due to any reason, thereby avoiding the accident because of the material being transported fall-off the machine.
3. Models of DSN Backstop for Belt Conveyor and Parameters
4. Details of DSN Backstop for Belt Conveyor
A) How it works:
Several irregular blocks are arranged regularly between outer ring and inner ring. When the inner ring is rotating in the working direction, the irregular blocks contact with the outer ring and inner ring gently. When the inner ring rotates in the counter-working direction, irregular blocks will be deflect driven by spring force and wedge outer ring and inner ring closer together to afford backstop torque.
B) Installation Size:
C) The Design of Iron Block:
Iron block is used to locate torque arm. It must have enough resistance to shear strength (pressure). When user selected arm length is different, the force taken by iron block also changes. The pin hole on the iron block must be long and be installed at the same direction of torque arm, to relieve backstop outer race from undue parallel forces. When backstopping, the pin on the iron block has no force affected. Its function at this time is to prevent reverse rotation at normal runtime.
D) Torque Arm and Iron Block Stress Diagram:
Following is the minimum force taken by the iron block when torque arm length is standard.
Clearance: the clearance between backstop torque arm bottom and stirrup surface is recommended to be 8-12 mm.
