Embodiment 1

[0030] refer to figure 1 , this embodiment provides a convenient bracket hanging ring for live work on transmission lines. All the work done by the operators on the tower is transferred to the new bracket hanging ring. It only takes 15 minutes to replace a string of 110-220kV transmission line tension insulators, which greatly reduces the working time and reduces the safety risk of personnel. , which also reduces the labor intensity of the staff, including the clamp unit 100 and the hanging ring unit 200, wherein the clamp unit 100 includes a clamp 101, a hook 102 located at one end of the clamp 101, and a connection installation located at the other end of the clamp 101 Hole 103, the clamping plate 101 is provided with a through hole 101a; the clamping plate 101 is the big knife card, the fixed pulley on the original transmission line live replacement insulator string big knife card is removed, and the clamp unit 100 and the hanging ring unit 200 are installed, The clamping ...

Embodiment 2

[0035] refer to Figure 1-7 , is the second embodiment of the present invention, this embodiment is based on the previous embodiment, and differs from the previous embodiment in that: when the distance between the hanging ring K and the card board 101 is determined, because the hanging ring K is used for Suspend the insulating rope, and the insulating rope is connected to the insulator to be replaced, so the hanging ring K may be shifted under the action of gravity, so in this embodiment, once the position of the hanging ring K is determined, the hanging ring K K is fixed to prevent deviation.

[0036] Specifically, the peripheral surface of the adjusting rod 201 is provided with an external thread 201a, and the hanging ring unit 200 also includes a rotating part 203, and the rotating part 203 is provided with a threaded hole 203a, and the threaded hole 203a is connected with the external thread 201a, that is, the rotating part 203 and the adjusting rod 201 The threaded conne...

Abstract

The invention discloses a convenient bracket hanging ring for live work on a power transmission line, which comprises a fixture unit, including a clamping plate, a clamping hook located at one end of the clamping plate, and a connection installation hole located at the other end of the clamping plate. A through hole is provided on the card board; the hanging ring unit includes an adjusting rod located in the through hole, and a limit plate connected to one end of the adjusting rod, and the other end of the adjusting rod is connected to a hanging ring, so The hanging ring is an annular metal ring; the present invention can be used for live work on transmission lines, and can also be used for power outage maintenance work of similar projects. The whole process of live replacement of insulators will be completed by the operators themselves on the tower. Transferred to the new bracket hanging ring, it only takes 15 minutes to replace a string of 110-220kV transmission line tension insulators with power on, which greatly reduces the working time, reduces the safety risk of personnel, and reduces the labor intensity of the staff.

Description

technical field [0001] The invention relates to the field of electric power safety, in particular to a convenient bracket hanging ring for live work on power transmission lines. Background technique [0002] The insulator is one of the important components of the transmission line. It connects the cross-arm of the tower and the wire, and keeps the wire and the cross-arm at a safe distance at all times. When the phenomenon occurs, it is necessary to replace the defective insulators. Live work is undoubtedly the best way, which does not require line power outages and does not affect the reliability of system power supply. In the past, when live-replacing double-string insulators of overhead transmission lines, the two ends of the tool "bottle holder" for live-replacing insulators were usually fixed on the front and rear big knife cards, and the screw rods were tightened to loosen the insulator strings. After the personnel removed the string of insulators on the wire side, the...
