Description

Belt conveyor counterweight box, counterweight system and belt deviation correction method

technical field

The invention relates to the technical field of belt conveying equipment, in particular to a belt conveyor counterweight box, a counterweight system and a belt deviation correction method.

Background technique

Belt conveyor is a friction-driven machine that transports materials in a continuous manner, and is used in the transportation of bulk materials in the fields of metallurgy and mining. During the operation of the belt conveyor, it is necessary to ensure that the belt has sufficient tension. The counterweight box is used to tension the belt in the belt conveyor, using gravity to provide tension for the belt. The counterweight box can keep the tensioning force stable under various working conditions, and can automatically compensate for the elongation of the belt. It is the most widely used tensioning device at present.

The counterweight box in the prior art is usually an open iron box, and the purpose of counterweight is achieved by assembling weight blocks in bulk; in the process of loading the counterweight, it should be loaded according to the designed number of counterweight blocks. However, when loading on-site counterweights, installers often forget the number of counterweights that have been loaded, and it is easy to see that the weight of the counterweights shipped to the site does not match the design; in some cases, the installer will use stone Wait for heavy objects to load. The above conditions often result in the counterweight loading not matching the design counterweight. When the load is not enough, the belt conveyor will be insufficient in tension and the belt will slip; when the load is excessive, the tension will be too large, causing the equipment to be overstressed and affecting the service life of the equipment. There is a direct risk of an installation accident.
