Description

Technical Field

[0001] The present invention relates to the technical field of dump trucks, and more particularly to a front baffle movement compensation device for a dump truck and a usage method thereof. Background Art

[0002] At the tail of the carriage of the existing flat-push dump truck, there is a drum that drives the conveyor belt inside the carriage to move. Materials are placed on the conveyor belt. By relying on the movement of the drum and using the pushing of the front baffle inside the carriage, the goods can be pushed out, and unloading can be completed without the need to lift the carriage. It has the advantages of high stability, not easy to tip over, and small occupied space. After the front baffle moves from the front end of the carriage to the rear end, a compensation device is needed to move the front baffle to the front end of the carriage.

[0003] The compensation device uses a steel wire rope to pull the front baffle to move. One end of the steel wire rope is wound around the drum, and the other end bypasses the front end of the carriage and is fixed on the front baffle. Generally, only one steel wire rope is arranged on the drum in the existing compensation device. The other end of the steel wire rope is fixed in the middle of the front baffle through a guide pulley. The steel wire rope and the front baffle are arranged in parallel, and a tensioning structure is arranged between the steel wire rope and the front baffle to tension the steel wire rope. Using one steel wire rope to pull the front baffle, the force on the steel wire rope is relatively large; the steel wire rope is parallel to the front baffle, and the tension on the steel wire rope is decomposed into horizontal and vertical forces, and the tension is severely decomposed. Therefore, the working efficiency of the steel wire rope is relatively low, and it is easy to cause damage to the steel wire rope, and the smoothness of the movement of the front baffle is also poor.
