Balance weight tensioning device of belt conveyor

Abstract

The invention relates to the technical field of metallurgical equipment, in particular to a balance weight tensioning device of a belt conveyor. The device comprises a conveyor belt. The conveyor beltis arranged on a redirection roller, the redirection roller is arranged on a frame, and the frame is arranged on columns which are symmetric in the left-right direction. The bottom ends of the columns are installed on the ground through fixing blocks, springs sleeve the bottoms of the columns, and the tops of the springs are connected with the frame through lifting hooks. The bottoms of the springs are provided with adjustment press plates, the two ends of each adjustment press plate are provided with adjustment screws for adjusting the tensioning degree of the springs, and a balance weight is hoisted on the bottom of the frame. According to the balance weight tensioning device, based on the length of the conveyor belt and the demand of the tensioning force, the tensioning pull force of the conveyor belt is adjusted and displayed. The balance weight tensioning device has an important protection effect on the service life of a cementation head of the conveyor belt, the stretching elongation ratio of the conveyor belt and the stable operation.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to a belt conveyor counterweight tensioning device. Background technique [0002] In the steel industry, sintering is the first production process, and the conveyor belt conveyor is one of the many equipments. The stable operation of the conveyor belt conveyor is an important part of ensuring the entire production process. Currently, there are two types of tensioning structures for belt conveyors: fixed manual tensioning screw tensioning and heavy hammer automatic tensioning. [0003] The characteristic of the fixed manual tightening screw is that the tension force of the belt is relatively small. It is mainly used in workplaces where the total length of the belt is short or the space is small and the heavy hammer type automatic tensioner cannot be installed. Its advantages are space saving and low cost. , the disadvantage is that it will slip once it is overloaded ...

Problems solved by technology

[0003] The characteristic of the fixed manual tightening screw is that the tension force of the belt is relatively small. It is mainly used in workplaces where the total length of the belt is short or the space is small and the heavy hammer type automatic tensioner cannot be installed. Its advantages are space saving and low cost. , the disadvantage is that it will slip once it is overloaded or the belt is loose

[0004] The characteristic of the heavy hammer type automatic tensioning is to use the weight of the heavy hammer to adjust the tension force, which is mainly used in the workplace with long belt length and open space; its advantages: under normal circumstances, the tension force can be automatically adjusted to meet the normal operation , Disadvantages: When the heavy hammer is too heavy, it will affect the service life of the belt cementing head. When the heavy hammer is too light, the belt will slip and cannot meet the normal operation. Once the belt cementing head breaks accidentally, the heavy hammer will fall freely and endanger the safety of personnel and equipment itself.
