technical field

The invention relates to the technical field of power tool accessories, in particular to a high-altitude operation buffer for maintenance of power transmission and distribution lines.

Background technique

When working at high places, the staff of transmission and distribution lines should not only use safety belts, but also use fall arrestors or second ropes to ensure the safety of the staff when they turn. However, the current anti-fall devices or the second anti-rope all have a common problem, which is the lack of effective buffer devices and automatic alarm devices. Once an accident occurs, the staff will fall quickly due to gravity, and will suddenly stop when reaching a certain point. Therefore, it is easy to be injured, and it is difficult for the underground staff to detect it in time, which delays the accident handling time and increases the injury risk of the falling personnel.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Please refer to Figures 1-2. In an embodiment of the present invention, a high-altitude operation buffer for power transmission and distribution line maintenance includes an alarm device 11 and a housing 12. The upper and lower ends of the housing 12 are respectively provided with two The No. 9 telescopic rod 9 and the No. 1 telescopic rod 1, the No. 2 telescopic rod 9 and the No. 1 telescopic rod 1 are exposed to one end of the outside of the housing 12 and are integrally formed with a pull ring, which is convenient for seat belt fixing. The No. 2 telescopic rod 9 and No. 1 telescopic rod 1 is positioned at one end of casing 12 inner sides to be respectively provided with No. 2 top board 8 and No. 1 top board 4, and No. 2 top board 8 and No. 1 top board 4 are circular, and No. 2 top board 8 and No. 1 top board 4 are connected with shell The inner wall of the body 12 is cooperatingly arranged, and the upper side of the No. 2 top plate 8 and the lower side of the No. 1 top plate 4 are respectively socketed on the No. 2 telescopic rod 9 and the No. 1 telescopic rod 1. The secondary spring 3 is a compression spring. , both ends of the housing 12 are provided with auxiliary spring accommodation groove 2, the auxiliary spring accommodation groove 2 is a cylindrical structure, when the first telescopic rod 1 and the second telescopic rod 9 are stretched, the auxiliary spring 3 is compressed , the No. 1 top plate 4 and No. 2 top plate 8 are stuck on the bottom and top inner wall of the housing 12, and the secondary spring 3 is accommodated through the secondary spring accommodating groove 2, so as to avoid the excessive contraction distance of the secondary spring 3, causing the secondary spring 3 damage, the top and bottom of the housing 12 are provided with a switch 10 on the inner wall of the outer ring of the secondary spring accommodation groove 2, the switch 10 is a sealed self-resetting button switch, and the switch 10 is on the top of the housing 12 and the bottom are respectively provided with a main spring limit post 5 on the lower side of the No. 2 top plate 8 and the upper middle part of the No. 1 top plate 4, and the end of the main spring limit post 5 is equipped with a buffer pad 6 , the buffer pad 6 is made of wear-resistant elastic rubber material, and the lower side of the No. The two ends are respectively fixed on the No. 1 top plate 4 and the No. 2 top plate 8, and the number of main springs 7 is four.
