Multi-point drive belt conveyor and chain tensioning method for infinite car group chain

Abstract

The invention discloses an electrodeless car unit chain multi-point driving belt type conveyor and a chain tensioning method. The conveyor comprises a bearing machine frame, a machine head driving device, a multi-point driving transmission mechanism and a bearing rail used for bearing the operation of the multi-point driving transmission mechanism; the bearing rail, the machine head driving device and the multi-point driving transmission mechanism are arranged on the bearing machine frame; a conveyor belt of the conveyor is driven by an electrodeless closed annular car unit chain; and the car unit chain is driven by a multi-point chain wheel, so that the maximum tension of the chain is reduced, and the tension of each chain segment of the car unit chain is ensured by adopting a segmented tensioning mode. The maximum tension of the chain is effectively reduced by the drive of the multi-point chain wheel, so that the stress of the machine frame during turning is improved, the carrying capacity of the chain and the conveying distance of the conveyor are improved, and the method is suitable for the development direction of large transport capacity and long transport distance of the conveyor; and the segmented tensioning method is adopted, so that the required tension of the car unit chain can be obtained, the tensioning adjusting amount of a machine tail is small, and the method is suitable for installing, adjusting and testing and maintaining of the long-distance conveyor.

Description

technical field [0001] The present invention relates to a multi-point drive endless car chain type belt conveyor and a chain tensioning method, in particular to a new type of multi-point drive car chain, a continuous conveying device that is driven by a trolley on the chain to pull the belt, and to The technical solution for the tensioning of the train chain; it is mostly used in long-distance continuous transportation occasions, and can transport bulk materials quickly and at low cost, and belongs to the technical field of bulk material transportation. Background technique [0002] Belt conveyor is a continuous conveying equipment, which has experienced a century of development history, and is widely used because of its strong transportation capacity and low transportation cost. With technological progress and production needs, the belt conveyor is developing towards the trend of long distance, large capacity, high power, and high strength; however, while the belt conveyor ...

Problems solved by technology

With technological progress and production needs, the belt conveyor is developing towards the trend of long distance, large capacity, high power, and high strength; however, while the belt conveyor is developing in the direction of large-scale and intelligent Some serious problems, among them: the roller has a large resistance to depression, the tape stretches and changes greatly, and the tension value of each point of the entire length is greatly different, which is prone to belt tension fluctuations, slipping, jumping and spreading, broken belts, and failure of the roller frame , roller shaft breakage and accessory device damage, etc., seriously restrict the application of conveyors
