Description

technical field [0001] The invention relates to the field of coal mine production equipment, in particular to a steel wire rope traction type coal mine underground belt conveyor cycle detection system. Background technique [0002] At present, in coal mine production, belt conveyor plays a vital role. In order to ensure large-capacity and high-power transmission, it is particularly important to monitor the working conditions of the belt conveyor. Due to the complex structure of the belt conveyor itself and the harsh working environment and poor lighting conditions, it is particularly difficult to accurately implement the detection of the belt conveyor. The traditional belt conveyor monitoring method mainly adopts on-site manual inspection. Manual inspections are a waste of manpower, inefficient, and pose a threat to personal safety due to poor working conditions.

AI Technical Summary

Problems solved by technology

This invention also has following problems: 1, track laying problem, runs into some complicated ground conditions and can't lay track

2. The problem of battery power supply. Since the belt conveyor is a long-distance material transportation machine, and the trolley is powered by batteries, its functions such as walking, detection, and obstacle removal need to consume battery power

[0004] Publication No. CN108773641A is the invention patent of "a new inspection robot for mining belt conveyor". Since there is no constraint of the track, the inspection robot must be remotely controlled by humans to inspect the belt conveyor. A depth camera is installed on the upper body of the robot, which can build a three-dimensional map of the surrounding environment. The pull switch can be pulled to stop the belt conveyor from working

This invention also has the following problems: 1. Depth camera cleaning problem. The conveyor belt is installed in the underground roadway of the coal mine. During the inspection in this environment, the camera mirror will be covered with coal dust, which makes the camera unable to build a three-dimensional map and the captured image is blurred. , not conducive to human remote control

2. The problem of battery power supply. Since the belt conveyor is a long-distance material transportation machine, and the trolley is powered by batteries, its walking, detection, and operation of the mechanical arm need to consume battery power.

3. The problem of inspection speed. The environmental information obtained through the camera is less when people are remotely controlled, which cannot make the robot achieve a better walking state. At the same time, the robot uses a crawler-type walking mechanism, and the walking speed is slow, and it is difficult to guarantee in the case of turning. Its control precision

This invention also has the following problems: 1. The camera cleaning problem. The conveyor belt is installed in the coal mine underground roadway. When patrolling in this environment, the camera mirror will be covered with coal dust, and the CCD camera will not be able to capture the ground track.

2. The problem of the running track of the inspection channel. The operating environment of the belt conveyor will be full of coal dust. When the coal dust falls to the ground, it will cover the running track of the inspection channel. 3. The adaptability of the mecanum wheel to complex ground conditions , the mecanum wheel, as an omnidirectional wheel, has high requirements on the flatness of the ground, and the ground around the belt conveyor is full of crushed coal and gravel, which is not suitable for the operation of the mecanum wheel

4. The problem of battery power supply. Since the belt conveyor is a long-distance material transportation machine, and the belt conveyor condition monitoring equipment is powered by batteries, its functions such as walking, detection, and the operation of the four-stage scissor linkage mechanism require consumes battery power

This invention also has the following problems: 1. The camera cleaning problem. The conveyor belt is installed in the coal mine underground roadway. When patrolling in this environment, the camera mirror will be covered with coal dust, and the camera will not be able to capture images.

2. The real-time problem of belt conveyor fault detection. The inspection robot is fixed at a certain position of the belt conveyor, and it will only detect the conveyor belt at this position, while the belt conveyor is a long-distance Material Handling Machinery, Accidents Can Happen Anywhere

3. The fault of the idler roller cannot be detected

This invention also has the following problems: 1. The camera cleaning problem. The conveyor belt is installed in the coal mine underground roadway. When patrolling in this environment, the camera mirror will be covered with coal dust, and the camera will not be able to capture images.

2. The real-time problem of belt conveyor fault detection. The inspection robot can move along the laying direction of the belt conveyor, but because the belt conveyor runs a long distance, it costs a lot to complete a belt conveyor inspection task. too long

3. The laying problem of the rack track, the rack used by the belt conveyor condition monitoring equipment can only be laid along a straight line path

This invention also has the following problems: 1. The layout of the guide rails, the synchronous belt device and the guide rails cannot be installed in curved roadways

2. The real-time problem of belt conveyor fault detection. The inspection robot can move along the laying direction of the belt conveyor, but because the belt conveyor runs a long distance, it costs a lot to complete a belt conveyor inspection task. too long

[0009] From the above six patents, it can be seen that the existing coal mine belt conveyor inspection system or belt conveyor condition monitoring equipment generally has the following problems: 1. Power supply problem, because the belt conveyor is a long-distance material transportation machine The running mechanism, detection sensors, monitoring cameras, etc. installed on the inspection robot, inspection system or belt conveyor condition monitoring equipment all need power dissipation energy to operate, and the battery power supply alone cannot support the inspection robot, inspection system or belt conveyor. Conveyor status monitoring equipment to complete a belt conveyor inspection

2. The cleaning problem of the camera. The conveyor belt is installed in the underground roadway of the coal mine. In this environment, the ordinary camera lens will be covered with coal dust during inspections, and the camera cannot capture images.

4. The problem of real-time fault detection of belt conveyors. The inspection system or belt conveyor status monitoring equipment involved in the above-mentioned patents only inspects the belt conveyor through a single device. Since the belt conveyor is from the head to the The distance at the tail of the machine is very long, and it takes a long time for a single device to complete a belt conveyor inspection, and it is impossible to detect the operation status of any position of the belt conveyor in time

Therefore, the detection effect of the existing detection methods is unstable, the monitoring efficiency is low, the accuracy is not high, and it is difficult to apply in harsh environments such as roadways
