Description

Intelligent safety belt

Technical Field

The invention relates to the technical field of electric tools, in particular to an intelligent safety belt.

Background

The construction site works at high places, and overlapping and crossing operations are quite many. In order to prevent the operator from falling at a certain height and position, the operator must hang the safety belt when working at a high altitude and a high place. In the actual situation, operators often unwind the safety belt in the high-altitude moving process, so that the safety belt protection is lost, and the high-altitude falling occurs; or the high-altitude operators wear the safety belts, and the safety belts are unfastened for various reasons, so that the high-altitude falling is caused by the fact that the safety belts are not strictly worn in the whole process. The existing safety belt cannot be uploaded to the specific use position, and safety management staff cannot master whether the high-altitude operation staff wear the safety belt strictly in the whole process, so that potential safety hazards are caused.

The construction site works at high places, and overlapping and crossing operations are quite many. In order to prevent the possible falling of an operator at a certain height and position, the operator must tie up a safety belt when working at a high altitude and a high altitude, the safety belt is hung with a backup rope, and the backup rope must be hung at a high altitude (the backup rope of the safety belt is hung at the high altitude, and people work below to be called as hanging high altitude and low altitude, which is a relatively safe and reasonable scientific system hanging method, which can reduce the actual impact distance when falling occurs, and prevent people from not playing a role in the falling process of the backup rope of the safety belt, and human bodies from falling to the ground to cause casualties). On the contrary, the safety belt backup rope is hung at a low position for high use, namely, the safety belt backup rope is tied at the low position, and a person works at a high position. This is an unsafe method of tying, because when a fall occurs, the distance of the actual impact increases, both the person and the rope are subjected to a large impact load, and it is also possible that the person has fallen to the ground, and the backup rope has not yet been functional. Therefore, the backup rope of the safety belt must be hung up and down for low use, and the low hanging up and high use is stopped. The conventional safety belt backup rope can not be detected and remotely monitored if the safety belt backup rope is hung down or not.
