Description

Technical Field

[0001] The utility model belongs to the technical field of conveyor application, and particularly relates to a belt deviation adjusting device. Background Art

[0002] The underground raw coal transportation system is mainly carried out by belt conveyors. Due to the long service life of the belt, the edge wear causes inconsistent belt width, the belt is not straight at the drop point, and the material cannot fall on the center line area of ​​the belt. When the amount of coal is large, the material spreads to the edge of the belt, which can easily cause the belt to deviate and scatter in the machine lane.

[0003] In the Chinese utility model patent with publication number CN219407968U, a belt conveyor deviation adjustment device is disclosed. The lower support plate is moved up or down by an adjustment mechanism. When the lower support plate is close to or away from the upper support plate, the distance between the upper support plate and the lower support plate changes, so that the bracket rotates along the fixed frame. At this time, the movable base makes a linear motion on the lower support plate, and the angle between the roller and the mounting frame can be adjusted to meet the deviation adjustment requirements. Compared with the setting of the arc rod, the limit column can not only limit the moving position of the movable base, but also help to reduce friction. Since the stability during deviation adjustment is improved, the problem of increasing deviation adjustment resistance due to excessive friction is avoided. The mounting frame is detachably connected to the belt conveyor frame, which is convenient for manual disassembly and maintenance, and reduces maintenance time.

[0004] However, the above solution requires the staff to monitor in real time whether the position of the belt is offset, which wastes manpower. In addition, the roller lacks a limit on the belt, and the belt is easily bent under stress. Utility Model Content
