Problems solved by technology

In the process of controlling the deviation of the conveyor belt of the belt conveyor, the precise movement of the deviation correction roller is the prerequisite for a good deviation correction effect. During the movement of the conveyor belt, the long-term impact of the conveyor belt on the deviation correction roller may easily lead to deviation The roller has offset or deformation that is difficult to identify manually, and after the conveyor belt is corrected, due to factors such as the slack of the conveyor belt itself or the change of the trajectory, the tension of the conveyor belt will change after the correction, causing the conveyor belt to easily run again. Therefore, a control system for underground belt conveyors is proposed to solve the above problems

Embodiment 1

[0029] see Figure 1-5 , the present invention provides a control system for an underground belt conveyor, which includes a deviation detection module 1, a video image acquisition module 20, an image data processing module 21, a deviation correction control module 5, a tension strength detection module 22 and The deviation correction height adjustment module 17, the deviation detection module 1 is based on the maximum deviation range of the deviation fault of the conveyor belt, and detects whether the deviation fault occurs on the conveyor belt; the video image acquisition module 20 is used for conveying The image information of the belt is collected; the image data processing module 21 processes and extracts the image information of the conveyor belt collected by the video image acquisition module 20, and judges the direction of the conveyor belt deviation according to the obtained conveyor belt edge straight line feature The correction control module 5 includes a correction ...

Embodiment 2

[0040] When the conveyor belt is used on the belt conveyor, if the conveyor belt deviates by 5%, the conveyor belt deviation fault will occur. In this state, the wear of the conveyor belt will increase and even dragging will occur. The limit detection module 1 will detect whether the deviation of the conveyor belt occurs. When the conveyor belt deviates by more than 5%, the conveyor belt will first reach between the infrared detection components 2 in the deviation detection module 1, and the infrared detection component The infrared beam emitted by 2 is blocked, and then the conveyor belt is in contact with the anti-falling roller assembly 4, and the anti-dropping roller assembly 4 will limit the conveyor belt to avoid the phenomenon that the conveyor belt continues to deviate or the conveyor belt falls off, and the alarm component 3. After the infrared light beam emitted by the infrared detection component 2 is blocked, an alarm is issued to remind the operator of a deviation ...

Embodiment 3

[0042] The conveyor belt has been in contact with the correction roller assembly 9 for a long time. When the conveyor belt moves, it exerts an unstable impact on the correction roller assembly 9 for a long time, resulting in the deformation and bending of the correction roller shaft 8, resulting in inaccurate correction. During the normal correction process, the correction The roller shaft rod 8 drives the deviation correction roller assembly 9 to offset the angle. After the deviation, the deviation correction roller shaft rod 8 will drive the sliding of the roller edge displacement detection slider 13 through the limit rod 10 and the rotary block assembly 12, and pass the displacement The sensor assembly 15 detects the sliding distance of the roller edge displacement detection slider 13 on both sides in real time. When the impact force of the conveyor belt causes the deformation or bending of the correction roller shaft 8, in the process of not correcting the deviation, the fir...

Abstract

The invention discloses a control system for an underground belt conveyor, which includes a deviation overrun detection module, a deviation correction control module, a tension strength detection module and a deviation correction height adjustment module. The deviation correction control module includes a deviation correction roller assembly, and the deviation correction roller assembly performs deviation correction control on the conveyor belt. The tension strength detection module is used to detect the tension of the conveyor belt after deviation correction. The correction height adjustment module controls the tension of the conveyor belt while the correction control module is correcting the deviation. The invention measures the displacement of the roller edges on both sides of the correction roller assembly to avoid the failure or even aggravation of the correction caused by the asymmetrical movement of the correction roller. In the case of a deviation fault, the conveyor belt is corrected for deviation control, and the tension control of the conveyor belt is ensured during the deviation correction process, so as to avoid the deviation or slippage of the conveyor belt due to changes in the tension strength after deviation correction.

Description

technical field [0001] The invention relates to the technical field of belt conveyors, in particular to a control system and a use method of an underground belt conveyor. Background technique [0002] The belt conveyor is the most widely used continuous transportation equipment in the mine, and the deviation of the conveyor belt is the most prone to failure. The deviation of the conveyor belt will directly cause the belt conveyor to fail to operate normally. Using image processing and Computer vision technology can realize the detection of conveyor belt deviation faults and reduce the burden on staff. In the process of controlling the deviation of the conveyor belt of the belt conveyor, the precise movement of the deviation correction roller is the prerequisite for a good deviation correction effect. During the movement of the conveyor belt, the long-term impact of the conveyor belt on the deviation correction roller may easily lead to deviation The roller has offset or def...
