Technical Field
[0001] The utility model relates to the technical field of electric power facilities, in particular to a safety belt with emergency functions and a high-altitude operation anti-falling device. Background Art
[0002] High-altitude work is a common working condition in the power industry. However, the frequent occurrence of high-altitude fall accidents in high-altitude work in recent years has also sounded the alarm for people's awareness of high-altitude work safety. The harm of such accidents is far greater than that of ordinary safety accidents. Therefore, how to do a good job in the safety protection of high-altitude work and fall prevention has become the top priority of the safety protection work of the entire power industry.
[0003] At present, the safety protection device for high-altitude work generally includes a safety guide component arranged on the iron tower and a safety belt connected to the anti-fall buckle of the safety guide component through a safety rope. The safety guide component includes a transverse guide rope, a vertical guide rope and a commutator arranged at the intersection of the transverse guide rope and the vertical guide rope, and the transverse guide rope and the vertical guide rope are connected to the iron tower through a locking assembly.
[0004] In order to improve safety and prevent workers from opening the safety rope at heights, the two ends of the safety rope are reliably connected to the anti-fall buckle and the safety belt, and only the workers on the ground can open it. Although this can improve safety, once an emergency such as an earthquake occurs, workers at heights cannot untie the safety rope and can only move along the safety guide component. The process of moving down along the safety guide component is cumbersome and slow, and it is easy to lose the best chance of escape and rescue. Utility Model Content

The base 31 is provided with an electromagnet 33 on the side of the first vertical plate 312 facing away from the second vertical plate 313, and the push rod 331 of the electromagnet 33 faces upward. The base 31 is provided with a controller 34 on the side of the second vertical plate 313 facing away from the first vertical plate 312, and the controller can provide electric energy to the electromagnet 33 and control the electromagnet 33 to be energized or de-energized according to the command signal sent by the remote controller.
[0041] In the connected state, the end of the stop pin 32 facing the first vertical plate 312 passes through the connection buckle 21 of the safety rope 2 and the avoidance hole 3121 on the first vertical plate 312 in sequence and extends to the side of the first vertical plate 312 facing away from the second vertical plate 313, the electromagnet 33 loses power, and the push rod 331 of the electromagnet 33 extends upward under the action of the first spring 332 and inserts into the stop pin 32 to prevent the stop pin 32 from retracting. At this time, the connecting component 3 is in a closed state, and the connection buckle 21 of the safety rope 2 is reliably connected to the connecting component 3.
[0042] When the safety rope 2 needs to be opened, a command signal is sent to the controller 34 through the remote control, and the controller 34 controls the electromagnet 33 to be energized, and the push rod 331 of the electromagnet 33 retracts and disengages from the stop pin 32.
