Belt tensioning device and belt conveyor applying same

Abstract

The invention belongs to the technical field of metallurgical belt feeding, and discloses a belt tensioning device and a belt conveyor applying the same. The belt tensioning device comprises a fixing frame and an adjusting device fixed in the fixing frame, the adjusting device comprises a pair of fixed steering rollers fixed in the fixing frame, a tensioning roller located above the fixed steering rollers and a spiral tensioning rod assembly, one end of the spiral tensioning rod assembly is connected with the tensioning roller, and the other end of the spiral tensioning rod assembly is connected with the fixing frame. The adjusting device is connected to the upper belt face of a belt of the belt conveyor, and the upper belt face sequentially passes through the first fixed steering roller and the tensioning roller in the pair of fixed steering rollers and then moves out of the second fixed steering roller in the pair of fixed steering rollers. The spiral tensioning rod assembly is configured to be capable of adjusting the displacement amount of the tensioning roller so as to adjust the tightness amount of the belt. The belt tensioning device is simple in structure and convenient to operate, and is not limited by sites in the application process.

Description

technical field [0001] The invention relates to the technical field of metallurgical belt feeding, in particular to a belt tensioning device and a belt conveyor using the same. Background technique [0002] Belt conveyors are widely used in the field of metallurgy. The belt tensioning device is an important part of the belt conveyor. It mainly provides tension for the belt of the belt conveyor to prevent the belt from slipping due to insufficient friction. [0003] At present, the belt tensioning device is usually a spiral tensioning type or a heavy hammer type. The belt tensioning device of the spiral tension type is installed at the wheel frame of the tail redirecting wheel of the belt conveyor, and the tail redirecting wheel is displaced by adjusting the length of the screw to tighten the belt in the length direction of the belt. The tensioning force of the belt tensioning device is limited and can only be applied to smaller belts, and it takes up a large space at the re...

AI Technical Summary

Problems solved by technology

The belt tensioning device of the spiral tension type is installed at the wheel frame of the tail redirecting wheel of the belt conveyor, and the tail redirecting wheel is displaced by adjusting the length of the screw to tighten the belt in the length direction of the belt. The tensioning force of the belt tensioning device is limited and can only be applied to smaller belts, and it takes up a large space at the rear of the rack, which brings some inconvenience to the site layout. In addition, the belt tensioning device is set at the rear turning wheel The device also results in the drive wheel being set only at the head, narrowing the field of application

The heavy hammer type belt tensioning device is installed on the lower belt surface of the belt. The tensioning roller is connected with the heavy hammer through a steel wire rope. By adjusting the weight of the heavy hammer, the displacement of the tensioning roller is adjusted to adjust the tightness of the belt. The belt tensioning device requires a certain space for installing the weight at the lower part of the belt, so the application field is also greatly restricted
