Description

Technical Field

[0001] The utility model relates to the technical field of self-moving tails, in particular to a walking type self-moving tail deviation adjustment structure. Background Art

[0002] The self-moving tail of a belt conveyor refers to a tail device that can move freely along the track of the conveyor belt. In coal mining, a belt conveyor step-type self-moving tail adjustment structure is usually used to adapt to complex working conditions and terrain, thereby increasing the maneuverability and stability of the machine body. At the same time, preventing the conveyor belt from running off track can reduce the wear and tear of the belt conveyor and extend the service life of the equipment.

[0003] A Chinese patent application with application number CN202320857324.1 discloses a walking-type self-moving tail deviation adjustment structure, which winds the conveyor belt through the roller part, and adjusts the conveyor belt through the deviation adjustment part. Specifically, the push plate is pushed by the first pneumatic cylinder, so that the deviation adjustment roller at the inner end of the push plate contacts the end surface of the conveyor belt, and the conveyor belt is pushed to reset to avoid deviation. The whole process does not require adjustment of the frame and the top screw, which is more convenient, time-saving and labor-saving. The two ends of the conveyor belt are also inclined during the winding process. At this time, the second articulated seat is lifted by the second pneumatic cylinder. Due to the articulated installation of the second articulated seat, the articulated installation of the second pneumatic cylinder itself and the articulated installation of the third articulated seat on the support arm, that is, It can push the rotating shaft and the deviation adjustment roller to change the angle of inclination, adapt to the conveyor belt end faces with different deviation angles, and has a wide range of applications. However, when the deviation adjustment structure of the above-mentioned step-type self-moving tail is in use, the mounting plate and the guide rail cooperate with each other to make the tail self-moving, and then the conveyor belt is adjusted by the first cylinder. However, it is difficult to protect the guide rail when the mounting plate and the guide rail cooperate with each other, so that a lot of dirty coal and mine scale is easily accumulated on the top of the guide rail, resulting in obstruction or instability of the roller movement, thereby affecting the normal operation of the conveyor and increasing the energy consumption of the equipment. At the same time, it will cause the conveyor belt to deviate or other operating abnormalities, thereby increasing the safety risks during operation, which is easy to cause personal injury or equipment damage.
