Description

TECHNICAL FIELD

[0002] In coal mine production operation, the belt conveying system as the key link of coal transportation, bears the important task of efficient, continuous transportation of the coal mined in the pit to the ground. Because the coal mine underground environment is complex and bad, the belt conveyor is long-term in high load, much dust, damp and other bad working conditions. The belt itself is prone to deviation, tearing, belt breakage and other conditions. Once this situation occurs, not only will the coal transportation be interrupted, but also the maintenance process will be time-consuming and laborious, and safety accidents may also be caused. Therefore, it is necessary to use a monitoring device to monitor and warn the running state.

[0003] According to the search, the Chinese patent document with publication number CN217497620U discloses a coal mine conveying belt monitoring device. The coal mine is conveyed by the belt in the conveyor body. When the belt is relaxed, the sliding block will descend due to the abutment of the spring and its own gravity. When the belt relaxation is large, the sliding block will descend to make the first contact mechanism internal structure contact, so that the alarm lamp is powered on to issue an alarm to remind the outside world. When the belt is broken, the sliding plate will descend due to gravity, and the second contact mechanism is driven by the sliding plate to descend and the second contact mechanism internal structure is powered off.

[0004] However, the above monitoring device can only monitor when the belt is relaxed in actual use, and cannot be monitored when the belt deviates. Therefore, there is the problem of incomplete monitoring. UTILITY MODEL CONTENTS
