Description
Technical field
The present invention relates to a kind of insulator clamp apparatus, particularly relate to a kind of insulator end clamp.
Background technology
Insulator clamp apparatus of the prior art, often the insulator at insulator string middle part can be taken off easily, if but need to change the side of wire was first insulator of insulator string, more difficult, because the jig head of jig screw rod one end can be stuck on the steel cap of first insulator, but to side of wire was but difficulty find fixing point, jig cannot be played a role, need an in addition additional device that can fix a little to replace the jig head of the jig screw rod other end, after tightening up like this screw rod, insulator string tension force could be unloaded, thereby by the replacing that relaxes of side of wire was first insulator, the very trouble but this kind of mode can seem, in prior art, also not yet find easier method or device.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of insulator end clamp, by using this jig, and can be easily, easily the side of wire was first insulator of insulator string is taken off.
For solving the problems of the technologies described above, the invention provides a kind of insulator end clamp, there is the jig screw rod of jig wire grip with the jig head being connected with jig screw rod one end except comprising, also comprise the link plate being connected with the described jig screw rod other end, side towards the link plate of described jig head is provided with swivel head, on this swivel head, be connected with for wire on the fixing fixture of triangle yoke plate.
By design link plate, replace the wherein jig head of one end of jig screw rod that is arranged on of the prior art, on link plate by swivel head is set, swivel head connect again for wire on the fixing fixture of triangle yoke plate, can be in the time taking off the side of wire was first insulator of insulator string, find a fixing point, and this fixing point is the triangle yoke plate on wire, as long as this one end of link plate is fixed on triangle yoke plate, can take off very easily, easily the side of wire was first insulator on insulator string.
Described fixture is fastened and is formed one group for clamping the cramping body of triangle yoke plate by clamp and cover plate.Mode by clamp and cover plate clamping is fixed with triangle yoke plate, and it is simple in structure, convenient.
At least two edges of described clamp are provided with the threaded top post for withstanding triangle yoke plate side.Object is to make triangle yoke plate fix and to locate with clamp and cover plate better.
Described clamp is provided with the backup protection button as insulator string backup protection hitch point, and the middle part of described backup protection button is provided with suppending hole.In work progress; the fracture if Work tool goes wrong; only second protection is carried out in reliable backup protection; avoid fault spread, but on insulator string, there is no the hanging point of backup protection, therefore backup protection button is set on clamp; connecting backup protection with steel wire rope buckles and tower body cross-arm; when after instrument (as lead screw) fracture, there is steel wire rope to hold insulator string, be unlikely to the expansion causing the accident due to broken tool.
The present invention has following useful technique effect:
(1) by the triangle yoke plate fixture of clamp and cover plate Combination Design, not only firm, and can bear large load, owing to having threaded top post adjustment location and increasing firmly function, can use on the identical yoke plate of specification cardinal principle applied range;
(2) design of swivel head, can make the construction of Renewal process easier and convenient, also can bear larger pulling force;
(3) design of backup protection button can be insulator string backup protection hitch point is provided in work progress, thereby prevents the expansion causing the accident due to broken tool.

Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Embodiment:
If Fig. 1 is to as shown in Fig. 4, a kind of insulator end clamp, comprises the jig head 2 that has the jig screw rod 1 of jig wire grip 14, be connected with jig screw rod 1 one end and the link plate 3 being connected with described jig screw rod 1 other end.Be provided with swivel head 4 towards the side of the link plate 3 of described jig head 2, on this swivel head 4, be connected with for wire on the fixing fixture of triangle yoke plate.Described fixture is fastened and is formed one group for clamping the cramping body of triangle yoke plate by clamp 5 and cover plate 6.Clamp 5 is to be mainly combined by bolt 9 clips with cover plate 6, thereby the triangle yoke plate on wire is clamped.Therefore on clamp 5 and cover plate 6, be all provided with bolt hole 10, and bolt hole 10 is designed to strip, is convenient to adjust the relative position between clamp 5 and cover plate 6.At least two edges of described clamp 5 are provided with the threaded top post 7 for withstanding triangle yoke plate side, and triangle yoke plate can be fixed and location with clamp 5 and cover plate 6 better.Described clamp 5 is provided with the backup protection button 8 as insulator string backup protection hitch point, and the middle part of described backup protection button 8 is provided with suppending hole.In work progress; the fracture if Work tool goes wrong; only second protection is carried out in reliable backup protection; avoid fault spread, but on insulator string, there is no the hitch point of backup protection, therefore backup protection button 8 is set on clamp 5; connect backup protection with steel wire rope and buckle 8 and tower body cross-arm; when after instrument (as lead screw) fracture, there is steel wire rope to hold insulator string, be unlikely to the expansion causing the accident due to broken tool.
