Abstract
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 jig repairing the transmission pressure of disconnected stock.
Background technology
The intact of transmission pressure is the important technology index ensureing normal transmission, according to the requirement of transmission of electricity maintenance procedure, transmission line breakage damage ratio must be repaired more than 25%, be connected with the disconnected stock of transmission pressure with preformed armor rods during repairing, and to identically with the thread pitch of transmission pressure be wrapped on transmission pressure, be then wound around parcel with protecting lines.If preformed armor rods is out of shape in winding, not neat, closely time, conductor overheating, the starting the arc, corona can be caused, even break.So preformed armor rods must closely neatly be wrapped on transmission pressure, this is one of effective ways reducing conductor corona.Repairing jig of the prior art is wrapped up completely by transmission pressure, preformed armor rods joint can not be observed directly whether be connected firmly, spiral angle also bad grasp when preformed armor rods is wound around, if the joint of preformed armor rods can not be fixed very well, it is very slow that follow-up winding repair procedure is carried out, preformed armor rods and protect lines and be wound around both uneven also tight, therefore cause the time-consuming effort of repair procedure, service work efficiency is very low.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of jig repairing the transmission pressure of disconnected stock, jig is sleeved on the transmission pressure of disconnected stock, have and be wrapped in angle on transmission pressure by moving horizontally conducting mechanism adjustment preformed armor rods, convenient observation preformed armor rods connector status, ensure the repairing quality of transmission pressure, improve the feature of overhaul efficiency.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of jig repairing the transmission pressure of disconnected stock, comprises the anchor ear housing of circular arc, clamping plate, left part bolt and right part bolt; Upper edge and the lower edge of described anchor ear housing are respectively equipped with clamping plate, described left part bolt also uses fastening nuts through the left part of upper and lower two clamping plate, described right part bolt also uses fastening nuts through the right part of upper and lower two clamping plate, is provided with and moves horizontally conducting mechanism between left part bolt and right part bolt.
To the further improvement that the present invention does be: described in move horizontally conducting mechanism and comprise guide-rail plate, slide plate and bolt, the clamping plate of described guide-rail plate lower end and bottom are hinged, guide-rail plate is provided with groove, described slide plate is positioned at the groove of guide-rail plate, slide plate is provided with slotted eye, and described bolt is passed slotted eye and is connected with guide-rail plate by screw thread; Slide plate is also provided with and makes preformed armor rods enter through wires hole in anchor ear housing.Described through wires hole is vertical holes, and the two ends of described vertical holes are respectively equipped with circular arc chamfering.
The beneficial effect adopting technique scheme to produce is: the present invention is sleeved on the transmission pressure of disconnected stock, angle on transmission pressure is wrapped in by moving horizontally conducting mechanism adjustment preformed armor rods, make it the winding angle meeting former wire, the anchor ear housing of circular arc has elasticity and can adapt to the different transmission pressure of diameter, whether in mending course, rotate jig can observe directly preformed armor rods joint and be connected firmly, whether preformed armor rods is wound around tight.Structure of the present invention is simple, easy to operate, can ensure the repairing quality of transmission pressure, improves the overhaul efficiency of transmission pressure.
