The invention discloses a clamp for repairing a strand-broken power transmission wire. The clamp comprises a circular arc-shaped loop shell, clamping plates, a left part bolt and a right part bolt; the clamping plate is arranged on the upper edge and the lower edge of the loop shell separately; the left part bolt passes through the left parts of the upper and lower clamping plates and are fastened by a nut; the right part bolt passes through the right parts of the upper and lower clamping plates and are fastened by the nut; and a horizontally movable wire mechanism is arranged between the left part bolt and the right part bolt. The clamp is arranged on the strand-broken power transmission wire in a sleeving manner; an angle of a preformed armor rod winding the power transmission wire is adjusted through the horizontally movable wire mechanism to enable the angle to accord with the winding angle of the original wire; the circular arc-shaped loop shell is elastic and can adapt to power transmission wires of different diameters; and whether the preformed armor rod joint is firmly connected or not and whether the preformed armor rod is tight in winding or not can be directly observed by turning the clamp in a repairing process. The clamp is simple in structure, convenient to operate, and capable of ensuring the repairing quality of the power transmission wire, and improving the overhauling efficiency of the power transmission wire.
Description
Technical field
The present invention relates to electric power overhaul technical field, particularly a kind of fixture for repairing stranded transmission pressure.
Background technology
The intact important technology index for being to ensure normal transmission of transmission pressure, requires according to transmission of electricity maintenance procedure,
Transmission line breakage damage ratio must be repaired more than 25%, the stranded connection of preformed armor rods and transmission pressure during repairing, and
And also identical with the thread pitch of transmission pressure to be wrapped on transmission pressure, then with shield lines winding parcel.If preformed
Silk in winding deformation, it is not neat, not tight when, conductor overheating, the starting the arc can be caused, corona, even broken.So preformed armor rods must
Closely neat must be wrapped on transmission pressure, this is one of the effective ways for reducing conductor corona.Repairing of the prior art
Fixture is that transmission pressure is fully wrapped around, it is impossible to observe directly whether preformed armor rods joint is connected firmly, when preformed armor rods winds
Spiral angle also bad grasp, if the joint of preformed armor rods can not be fixed very well, what follow-up winding repair procedure was carried out
Very slow, preformed armor rods is both uneven with shield lines winding or tight, therefore causes repair procedure time-consuming laborious, service work
Efficiency is very low.
The content of the invention
The technical problem to be solved is to provide a kind of fixture for repairing stranded transmission pressure, and fixture is set with
On stranded transmission pressure, the angle that preformed armor rods is wrapped on transmission pressure is adjusted with by moving horizontally conducting mechanism,
The characteristics of convenient observation preformed armor rods connector status, it is ensured that the repairing quality of transmission pressure, raising overhaul efficiency.
To solve above-mentioned technical problem, the technical solution used in the present invention is：A kind of stranded transmission pressure of repairing
Fixture, including the anchor ear housing of circular arc, clamping plate, left part bolt and right part bolt；The upper edge of the anchor ear housing and following
Along clamping plate is respectively equipped with, the left part bolt passes through the left part of upper and lower two clamping plates and is fastened with nut, and the right part bolt is worn
Cross the right part of upper and lower two clamping plates and fastened with nut, be provided between left part bolt and right part bolt and move horizontally wire machine
Structure.
It is to the further improvement that the present invention is done：The conducting mechanism that moves horizontally is including guide-rail plate, slide plate and positioning
Bolt, the guide-rail plate lower end is hinged with the clamping plate of bottom, and guide-rail plate is provided with groove, and the slide plate is located at the groove of guide-rail plate
It is interior, slotted eye is provided with slide plate, the bolt with guide-rail plate is connected through slotted eye and by screw thread；It is additionally provided with slide plate
Preformed armor rods is set to enter the through wires hole in anchor ear housing.The through wires hole is vertical holes, and the vertical holes is respectively arranged at two ends with circle
Arc chamfering.
It is using the beneficial effect produced by above-mentioned technical proposal：The present invention is sleeved on stranded transmission pressure, is led to
Cross and move horizontally the angle that conducting mechanism adjustment preformed armor rods is wrapped on transmission pressure, be allowed to meet the winding angle of former wire,
There is the anchor ear housing of circular arc elasticity to be suitable for the different transmission pressure of diameter, and fixture is rotated in mending course can directly be seen
Observe whether preformed Threaded Connector Coupling is connected firmly, whether preformed armor rods winding is tight.Present configuration is simple, easy to operate, it is ensured that
The repairing quality of transmission pressure, improves the overhaul efficiency of transmission pressure.
