Abstract
The utility model discloses an equipotential line rapid-disengagement clamp used during a helicopter live-line work process. The clamp comprises a left clamp body, a right clamp body, an extension spring, an installing hole, a smooth arc-shaped hole, a left long hole, a right long hole, a stop rod and a support rod. The equipotential line rapid-disengagement clamp used during a helicopter live-line work process has the advantages of convenient operation, safety and reliability. The clamp can ensure reliable connection of an equipotential line and a lead and further ensure rapid disengagement of the equipotential line from the lead in emergency.
Description
Technical field
The utility model belongs to high pressure power transmission and distribution fields, and a kind of helicopter live line working that relates in particular in the helicopter altitude hot-line operation breaks away from fixture fast with equipotential line.
Background technology
In superhigh pressure and the live line working of UHV transmission line helicopter, the operating personnel generally is positioned on the helicopter workbench transmission line wire, conductor spacer, stockbridge damper and insulator etc. is carried out the equipotential operation.During operation, for the impact on operating personnel and helicopter of the steady-state current guaranteeing operating personnel, helicopter and wire equipotential and prevent from producing because of capacity effect, usually by equipotential line, the job platform on helicopter and live wire are linked together to keep people, machine and wire equipotential.For guaranteeing to connect reliably, existing conventional equipotential line connecting clamp all has the rear successfully problem of disengagement that is difficult to fast that is connected with wire, therefore, (as strong wind, thunderstorm, short circuit etc.) are in an emergency in operation, when helicopter needs the ejection escape current potential, make it hightail wire and the serious consequence that causes serious accident with causing equipotential line to pin down helicopter.Need to guarantee equipotential line and wire positive connection, can in case of emergency hightail again the escaped electric charge transferring clamp of wire.
Summary of the invention
The purpose of this utility model is to provide a kind of helicopter live line working to break away from fast fixture with equipotential line, have easy to operate, safe and reliable, can guarantee equipotential line and wire positive connection, can in case of emergency hightail again the advantage of wire.
The technical scheme that realizes above-mentioned purpose is: a kind of helicopter live line working breaks away from fixture fast with equipotential line, comprises left caliper, right caliper body, extension spring, installing hole, level and smooth arc port, left slotted hole, right slotted hole, pin and support bar; Wherein:
described mounting hole site is in described left caliper lateral surface bottom, described left slotted hole is positioned at described left caliper lateral surface top, described support bar is articulated in described left slotted hole, described right slotted hole is positioned at described right caliper body lateral surface top, described pin is welded in described right slotted hole, described extension spring is riveted on described left caliper lateral surface and described right caliper body lateral surface, described left caliper medial surface top and described right caliper body medial surface top have described level and smooth arc port, be in the same place with described right caliper body center riveting in described left caliper center.
Above-mentioned installing hole is used for installing equipotential line.
The radian of above-mentioned level and smooth arc port and the diameter of folded wire match.
Owing to having adopted the utility model device, realized that a kind of helicopter live line working breaks away from fixture fast with equipotential line, have easy to operate, safe and reliable, can guarantee equipotential line and wire positive connection, can in case of emergency hightail again the advantage of wire.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Please refer to Fig. 1, Fig. 2 and Fig. 3, provided a kind of helicopter live line working in figure and broken away from fast fixture with equipotential line, comprise left caliper 1, right caliper body 2, extension spring 3, installing hole 4, level and smooth arc port 5, left slotted hole 6, right slotted hole 7, pin 8 and support bar 9; Wherein:
Installing hole 4 is positioned at left caliper 1 lateral surface bottom, left slotted hole 6 is positioned at left caliper 1 lateral surface top, support bar 9 is articulated in left slotted hole 6, right slotted hole 7 is positioned at right caliper body 2 lateral surface tops, pin 8 is welded in right slotted hole 7, extension spring 3 is riveted on left caliper 1 lateral surface and right caliper body 2 lateral surfaces, and left caliper 1 medial surface top and right caliper body 2 medial surface tops have level and smooth arc port 5, is in the same place with the center riveting of right caliper body 2 in the center of left caliper 1.
Installing hole 4 is used for installing equipotential line.
The radian of level and smooth arc port 5 and the diameter of folded wire match, and are used for guaranteeing abundant contact wire.
The pulling force of extension spring 3 has been guaranteed left caliper 1 and right caliper body 2 clamping wires.
Operation principle of the present utility model is to utilize the mechanical dimension of pin to guarantee to open jaw, utilizes spring tension to guarantee to tighten wire, and when the pulling force of the equipotential line pulling force greater than spring, fixture breaks away from wire fast.
Below embodiment has been described in detail the utility model by reference to the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details in embodiment should not consist of restriction of the present utility model, and the scope that the utility model will define with appended claims is as protection range of the present utility model.
