New clamping device for rope conveyors and elevators

Abstract

Currently, the main types of traction organ of conveyors and elevators are chains and rubberized belt. The use of rope traction is limited by the lack of a convenient design of attachment of the working body (scrapers, plates, buckets) to the rope. The existing types of attachment require adjustment of the pitch when pulling the rope and special devices for passing the couplings on the drive pulley. Fastening of these devices should be systematically controlled, as tightening is carried out by bolts.However, the rope pulling device has a number of advantages in comparison with the chain one: 6-8 times less weight, lower cost, greater reliability in operation and durability. At the same time, the design of pulleys, especially drive pulleys, is characterized by complexity and therefore relatively unreliable in operation. Sheaves for ropes with clamping couplings have a number of significant disadvantages and in the industry are used to a limited extent.
