Abstract

The utility model discloses an electrified general fixture of changing two clusters of straight line and the two cluster insulators of strain insulator, including three diagonal connection board spread grooves, three diagonal connection boards and fixture connecting hole, tripod connecting hole, lead screw standing groove, shutting pin. The utility model has the advantages of reasonable in design, simple structure, convenient to use, safe effective, simple to operate when the two cluster insulators of electrified change straight line, visual operation, it is accurate, fast, the utility model discloses can assemble lead screw and insulating arm -tie on ground in advance, pull on the shaft tower, tighten up the wire and carry the line, use manpower sparingly, reduce operating time and workload, practice thrift working cost.

Description

The fixture of the double strings of electrified replacing linear or two strings of strain insulators
Technical field
This utility model is related to the instrument that a kind of overhead transmission line changes insulator chain, more particularly to a kind of charged for replacement The General clamping of the double strings of straight line or two strings of strain insulators.
Background technology
In long-term operation, glass fiber reinforced plastic insulator can be sent out overhead transmission line due to thunderbolt, filth, forceful electric power field action etc. It is conigenous quick-fried, porcelain insulator can become low value or zero resistance insulator, and now, the dielectric strength of transmission line of electricity becomes can not meet Service requirement, can cause live wire to discharge shaft tower, cause line-to-ground short circuit, therefore, it is the service requirement for meeting circuit, Need to be changed to revealing insulator or null value, low resistance insulator.At present, when electrified replacing linear double insulator string is carried out Mainly adopt two methods:(1)The string assembly pulley method of insulation three, the method needs manpower to carry out carrying line, can only be little in line span, When loading is light, just can carry out, and straight line double insulator string often big span or across when two grades between adopt, loading Heavier, manpower carries line and tightens up relatively difficult, it is difficult to realize;(2)Changed with the combination of straight line screw mandrel and arm-tie etc., this kind of method, The installation of fixture and insulation pulling plate during operation must be carried out at the lower section scene of cross arm of tower, and staff lies prone and grasped on shaft tower Make, it is impossible to see the various parts below cross arm of tower, can only armrest sense grope to be carried out with working experience, install hard, consumption When effort, and dangerous hidden danger.
Utility model content
Technical problem to be solved in the utility model is to overcome the above defect, there is provided one kind can meet to be tightened up Line requirement is proposed, again the General clamping of the double strings of the convenient electrified replacing linear installed or two strings of strain insulators, meets job requirement, Simultaneously man-machine efficacy can be improved, it is time saving and energy saving.
In order to solve the problems, such as techniques described above, the double strings of electrified replacing linear described in the utility model or tension double-string insulation The fixture of son, including board, the board includes yoke plate connection end and screw mandrel connection end, and the screw mandrel connection end is connected with yoke plate The angle a of end upper limb is 25-35 degree, and the end of the screw mandrel connection end is provided with for through the screw mandrel groove of screw mandrel, the silk Symmetrical draw-in groove is provided with the front and back walls of bar groove.
Further, it is provided with locking piece at draw-in groove described in the utility model.
This utility model is the improvement to changing the existing wing fixture of insulator chain, and the board screw mandrel connection end is by changing Enter downward-sloping certain angle, make board net and cross arm of tower between after being arranged on straight line double insulator string triangle yoke plate From increase, on the one hand when tightening up or loosening screw mandrel, this clearance can meet the requirement of screw mandrel length to Ullage, on the other hand, Staff works on cross arm of tower, and inclined head can look at operation, and accurate, speed is fast;Have described in the utility model Fixture, can shift to an earlier date and assemble screw mandrel with insulation pulling plate on ground, pull on shaft tower, wire is carried out tightening up carry line, easy for installation, It is time saving and energy saving.
The beneficial effects of the utility model:There is reasonable in design, knot due to having used structure described above, this utility model Structure is simple, it is easy to use, safe effective the advantages of;Fixture after improvement is safe, practical, saves manpower, reduces Working time and workload, have saved job costs.
Description of the drawings
Fig. 1 is structural representation described in the utility model;
Fig. 2 be this utility model when in use with the connection diagram of adjacent components.
Specific embodiment
This utility model is described in further detail below in conjunction with the accompanying drawings.
The General clamping of the double strings of electrified replacing linear described in the utility model or two strings of strain insulators, including board 1, institute Board 1 is stated including yoke plate connection end 2 and screw mandrel connection end 3, the screw mandrel connection end 3 is with the angle a of the upper limb of yoke plate connection end 2 25-35 degree, the end of the screw mandrel connection end 3 is provided with for through the screw mandrel groove 4 of screw mandrel, the front and back walls of the screw mandrel groove 4 On be provided with symmetrical draw-in groove 5.
Further, it is provided with locking piece 6 at draw-in groove described in the utility model 5.
Embodiment:The downward-sloping folder with the upper limb of yoke plate connection end 2 in its screw mandrel connection end 3 of board described in the utility model 1 Angle a is 30 degree, so, is increased to the clearance H the cross-arm 7 of head of mast from the screw mandrel groove 4 of screw mandrel connection end end Greatly, on the one hand when tightening up or loosening screw mandrel 8, this clearance can meet the requirement of screw mandrel length, on the other hand, staff Work on cross arm of tower, vision can and, look at operation personally, accuracy rate is high, and speed is fast;Screw mandrel groove 4 described in the utility model Front and back walls on symmetrical draw-in groove 5 is set, screw mandrel 8 can be assembled with insulation pulling plate 9 on ground, will screw mandrel 8 pass through screw mandrel Groove 4, the front and rear card of nut bail 10 on screw mandrel in draw-in groove 5, shaft tower in lifting, due to action of gravity, the bail of feed screw nut 10 are stuck in draw-in groove 5, will not slip, and in order to for the sake of more safety, locking piece 6 be arranged at the draw-in groove 5, bail 10 are locked Firmly.After this utility model assembling wire is carried out tightening up and carry line, it is easy for installation, it is time saving and energy saving.The double string insulation of electrified replacing linear Son can also be worn assembly pulley method and changed when loading is lighter with insulation three, but in case of loading it is heavier when, cannot receive Tight lifting lead wire, now, using fixture described in the utility model, straight line screw mandrel is combined with insulation pulling plate, you can solve problem.
A kind of embodiment of the present utility model is these are only, as long as having used structure described above, this reality all should be fallen into With new protection domain.
