New clamping device for rope conveyors and elevators
Abstract
Currently, the main types of traction elements of conveyors and elevators are chains and rubberized belts. The use of a rope traction element is limited by the lack of a convenient design for attaching the working element (scrapers, plates, buckets) to the rope. The existing types of attachment require pitch adjustment when the rope stretches and special devices for passing couplings over the drive pulley. The fastening of these devices must be systematically controlled, since tightening is done with bolts. However, the rope traction element has a number of advantages compared to the chain one: weight is 6–8 times lower, lower cost, greater operational reliability and strength. At the same time, the design of pulleys, especially drive pulleys, is complex and therefore relatively unreliable in operation. Pulleys for ropes with clamping couplings have a number of significant disadvantages and are used to a limited extent in industry.
