Description
Technical Field
The patent relates to a safety protection device, in particular to an overhead working unhooking alarm safety belt.
Background
According to the regulations of the national net company on the notice about further increasing the forces of violation punishment and punishment of safety production, the condition that the high-altitude operation, climbing or transferring the operation position is out of protection belongs to the class I serious violation, but in actual work, part of high-altitude operation personnel cannot tie the safety belt in time due to negligence or the safety belt is unhooked accidentally in the working process, so that the violation even causes safety accidents; therefore, an alarm is arranged on the safety belt to alarm the condition that the safety belt is not fastened or the safety belt is unhooked during high-altitude operation.
The conventional safety belt alarm is generally triggered by a travel switch or a magnetic attraction type, or triggered by an electronic chip sensing mode, and also is judged by a sensing circuit signal mode, but the alarm needs to be closely sensed or connected with a safety belt body, and is suitable for an alarm that a safety hook bypasses a mast or other structures (the mast or other structures are called as a mast hereinafter for simplicity in description) and returns to the waist to be connected with a D-shaped ring, or the safety hook is directly hung on the mast, and the alarm sound is only a beeping sound, and a surrounding rod belt, a backup rope and the like are not distinguished.
In the high-altitude operation process, the shape and the position of the mast which can be surrounded by the safety hook are different, so that the safety hook cannot be directly hung on the mast because of the large size of the mast, or cannot be returned to the waist by bypassing the mast to be connected with the D-shaped ring because of the long distance, and only a mode that the safety hook bypasses the mast to beat a small ring can be adopted; however, for the safety hook, the safety hook bypasses the mast to form a small loop, the working condition of the D-shaped loop of the waist of the safety belt is not returned, and the alarm cannot judge and unhook to alarm.
In addition, the prior safety belt alarm can also cause false alarm due to poor contact between the safety hook and the D-shaped ring; when individual high-altitude operators move at high places, the safety hooks of the safety belts are released by the ship to move, so that serious artificial violations are caused; moreover, as the supervisory personnel and the control ball are on the ground, the rule violations cannot be stopped in time, and the supervision is not performed.
