Abstract
The invention discloses an insulator end clamp. In addition to a clamp screw provided with a clamp wire tightener and a clamp head connected with one end of the clamp screw, the insulator end clamp comprises a hanging plate connected with the other end of the clamp screw, wherein the side of the hanging plate facing the clamp head is provided with a rotating head, and a fixed device which is fixed to a triangular yoke plate on a conductor is connected to the rotating head. The fixed device is buckled by a clamping plate and a cover plate to form a group of clamping bodies for clamping the triangular yoke plate. Threaded support columns which are used for supporting the sides of the triangular yoke plate are arranged on at least two edges of the clamping plate. A backup protection buckle which serves as a backup protection hanging point of an insulator string is arranged on the clamping plate, and a hanging hole is formed in the middle of the backup protection buckle. The insulator end clamp is firm and can bear a heavy load. Because the threaded supporting columns have a positioning adjustment function and a firmness improvement function, the insulator end clamp can be applied to yoke plates of substantially same specification, and has a wide application range.
Description
Technical field
The present invention relates to a kind of insulator clamp apparatus, more particularly to a kind of insulator end clamp.
Background technology
Insulator clamp apparatus of the prior art, tend to easily take off the insulator in the middle part of insulator chain, but
The side of wire first insulator if necessary to change insulator string, then relatively difficult, because the fixture head of fixture screw rod one end
Can be stuck on the steel cap of first insulator, but but difficulty finds fixing point to side of wire, so that fixture cannot be played a role, need
In addition to add a device that can fix a little to replace the fixture head of the fixture screw rod other end, could incite somebody to action after so tightening up screw rod
Insulator string tension force unloads, thus side of wire first insulator is relaxed replacing, but this kind of mode can seem very numb
Tired, also not yet find easier method or apparatus in prior art.
Content of the invention
The technical problem to be solved is to provide a kind of insulator end clamp, by using this fixture, can be light
Pine, easily the side of wire first insulator of insulator string is taken off.
For solving above-mentioned technical problem, the invention provides a kind of insulator end clamp, tight except including there is fixture
Outside the fixture screw rod of line device and the fixture head that is connected with fixture screw rod one end, also include being connected with the described fixture screw rod other end
Link plate, is provided with swivel head towards the side of the link plate of described fixture head, this swivel head is connected with for wire on triangle
The fixing fixing device of yoke plate.
By designing link plate, substituted for the fixture head being arranged on fixture screw rod wherein one end of the prior art, in link plate
Above pass through to arrange swivel head, swivel head is connected to the fixing device fixing with the triangle yoke plate on wire again, can take off
During the side of wire first insulator of insulator chain, find a fixing point, and this fixing point is the triangle yoke plate on wire, only
This one end of link plate is fixed on triangle yoke plate, you can very easily, easily take off the side of wire first on insulator chain
Piece insulator.
Described fixing device is fastened by clamp and cover plate and forms one group of cramping body for clamping triangle yoke plate.By clamp
To fix with triangle yoke plate with the mode of cover plate clamping, its structure is simple, convenient.
At least two edges of described clamp are provided with the threaded top post for withstanding triangle yoke plate side.Purpose is to make three
Angle yoke plate preferably can be fixed with clamp and cover plate and position.
Described clamp is provided with the back-up protection button as insulator chain back-up protection hitch point, described back-up protection button
Middle part is provided with suppending hole.In work progress, the fracture if Work tool goes wrong, only reliable back-up protection carries out secondary guarantor
Shield, it is to avoid fault spread, but the hanging point of back-up protection is not had on insulator chain, therefore back-up protection button is set on clamp, use
Steel wire rope connects back-up protection and buckles and tower body cross-arm, after instrument (as lead screw) ruptures, has steel wire rope to hold insulator chain, no
As for the expansion being caused the accident due to broken tool.
The present invention has following Advantageous Effects:
(1) pass through the triangle yoke plate fixing device of clamp and cover plate combination design, not only firmly, and can bear negative greatly
Lotus, due to having threaded top post adjustment positioning and increasing firm function, can apply model using on the yoke plate that specification is substantially the same
Enclose wide;
(2) design of swivel head, can make the construction of Renewal process easier and convenient, also can bear bigger pulling force;
(3) design of back-up protection button, can provide back-up protection hitch point for insulator chain in work progress, thus anti-
The expansion only being caused the accident due to broken tool.

Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described in further detail to the present invention.
Embodiment:
As shown in Fig. 1 to Fig. 4, a kind of insulator end clamp, including the fixture screw rod 1 with fixture tightener 14 and
Fixture head 2 and the link plate 3 being connected with described fixture screw rod 1 other end that fixture screw rod 1 one end connects.Towards described fixture head 2
The side of link plate 3 be provided with swivel head 4, this swivel head 4 is connected with for wire on the fixing fixing dress of triangle yoke plate
Put.Described fixing device is fastened by clamp 5 and cover plate 6 and forms one group of cramping body for clamping triangle yoke plate.Clamp 5 and cover plate
6 mainly pass through bolt 9 fixation snaps together, thus the triangle yoke plate on wire is clamped.Therefore on clamp 5 and cover plate 6
It is designed with bolt hole 10, and bolt hole 10 is designed to strip, be conveniently adjusted the relative position between clamp 5 and cover plate 6.Described
At least two edges of clamp 5 are provided with the threaded top post 7 for withstanding triangle yoke plate side, enable triangle yoke plate preferably with
