[0002] In the coal mine production activities, safe operation is very important. In order to prevent fire, smoke sensor needs to be installed above the roadway roof of the monitored equipment, especially at the belt conveyor for coal transportation, the safe operation of the belt conveyor belt is very important. In recent years, in the safety accidents of coal mine, the accidents caused by the operation of the belt conveyor are not few, and the belt slip is easy to cause the friction between the belt and the driving drum to generate heat, resulting in fire. Therefore, the smoke protection of the belt conveyor must be sensitive and reliable, once the incorrect hanging position, sensor failure and other conditions occur, it will be judged as a major safety hazard of coal mine. Such major safety hazards will lead to mine production rectification, even mine closure and other serious consequences. In the field of safety management, the smoke sensor needs to be tested every day to ensure that the smoke sensor is sensitive and reliable. Since the smoke sensor is hung on the roof directly above the belt conveyor, personnel need to climb to the top of the belt conveyor for testing, and in this process, there are safety hazards of climbing operation and safety risks of belt conveyor misstart, which seriously threaten the safety of the operating personnel. SUMMARY

[0003] In view of the above problems, the utility model provides a coal mine underground smoke sensor test convenient device, which can pull the smoke sensor from the roadway roof to the personnel side of the belt conveyor, and land at a height convenient for personnel to test, and use smoke to test the smoke sensor, thereby avoiding the safety risks caused by personnel climbing operation and ensuring the safety of personnel operation.
