Abstract
A kind of insulator nut fastener, comprise the sleeve, some joint insulating bars and the turning handle that are connected successively, described sleeve is hollow structure, and the shape of its inside is corresponding with insulator bottom nut; Be lug boss with insulating bar one end of sleeve connection, the shape of lug boss is corresponding with the shape in sleeve; Two joint insulating bars are connected by the plug portion being arranged at insulating bar one end.Above-mentioned insulator nut fastener can realize the fastening of insulator bottle when circuit does not have a power failure, have the advantages that structure is simple, easy to operate.
Description
Technical field
The utility model relates to the fastener of nut in electric power transfer construction work field, particularly a kind of high-voltage fence.
Background technology
Inclined on high-tension line or pillar insulator are generally fixed by high pressure nut.Due in long use procedure, high pressure nut easily produces loosening, causes the crooked of insulator bottle, if processed not in time, insulator can be caused to come off and cause line fault.
The situation that current distribution causes insulator bottle crooked because of high pressure nut loosening is a lot, the measure one taked rectifies and improves in conjunction with power failure, this measure is because limit by power failure range, can only complete the work of levelling body at power failure range, performance is few and can not ensure to complete whole rectification within a time between overhauls(TBO).Measure two utilizes aerial lift device with insulated arm to carry out live line working levelling insulator bottle, and because the workload often locating operation is large, the recruitment used time is more; Because actual geographic position limit, near high-tension line, cannot be able to not finish the work in a lot of situation of aerial lift device with insulated arm.
Utility model content
Technical problem to be solved in the utility model is the defect overcoming prior art, provides a kind of insulator nut fastener, can realize the fastening of insulator bottle, have the advantages that structure is simple, easy to operate when circuit does not have a power failure.
Technical problem of the present utility model realizes with following technical proposals:
A kind of insulator nut fastener, comprise the sleeve, some joint insulating bars and the turning handle that are connected successively, described sleeve is hollow structure, and the shape of its inside is corresponding with insulator bottom nut; Be lug boss with upper insulating bar one end of sleeve connection, the shape of lug boss is corresponding with the shape in sleeve; Two joint insulating bars are connected by the plug portion being arranged at insulating bar one end.
Above-mentioned insulator nut fastener, the quantity of described insulating bar is 4-5 joint, and the length often saving insulating bar is 1.5m.
Above-mentioned insulator nut fastener, described turning handle is ratchet spanner.
The utility model to be realized when not having a power failure on ground in the face of insulator carries out fastening by interconnective some insulating bar.Insulating bar can realize flexible dismounting, the applicable requirement with differing heights, and insulating bar is designed to hollow and intensity and meets the demands, light during use.Sleeve can realize different model and change flexibly, is applicable to different insulator nuts.The utility model structure is simple, easy to use, not only increases operating efficiency, also reduces the labour intensity of operator.Owing to reducing line outage number of times, improve the reliability of power supply.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, each list of reference numerals is: 1, sleeve, 21, upper insulating bar, 22, lower insulating bar, 3, ratchet spanner, 4, lug boss, 5, plug portion.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises the sleeve 1, some joint insulating bars and the ratchet spanner 3 that are connected successively.Described sleeve 1 is hollow structure, and the shape in sleeve 1 is corresponding with insulator bottom nut.Upper insulating bar 21 one end be connected with sleeve 1 is lug boss 4, and the shape of lug boss 4 is corresponding with the shape in sleeve.Two joint insulating bars are connected by the plug portion 5 being arranged at insulating bar one end, and described plug portion 5 is cylindrical, and the both sides corresponding at its curved surface are respectively equipped with semi-cylindrical hill, for fixing two joint insulating bars.The groove corresponding with ratchet spanner 3 is had bottom lower insulating bar 22 of next joint.Lower insulating bar 22 is connected by inserting with ratchet spanner 3.Sleeve 1 puts insulator bottom nut, and upper insulating bar 21 inserts in sleeve 1, and ratchet spanner 3, by left-right rotation, drives insulating bar, sleeve 1 and insulator nut to carry out screwing and unclamping.
Described sleeve 1 can be arranged to different models according to the size of insulator nut.The quantity of described insulating bar is generally 4-5 joint, and often saving insulating bar length is 1.5m.
Described ratchet spanner 3 has 1 rotary indicator, rotates to left side for unclamping nut, rotates to right side for clamp nut.
Below the course of work of the present utility model is described further:
Select the sleeve 1 corresponding with nut to be installed on the front end of upper insulating bar 21 during construction, select the insulating bar of varying number according to field condition, ratchet spanner 3 is installed on next end saved of insulating bar.Sleeve 1 is aimed at loosening nut (if nut lose can by nut to be installed as in sleeve to the screw rod on quasi-insulator).During one man operation: operator catches insulating bar rotating ratchet spanner on the other hand on the other hand, until fastening nuts.Very high for shaft tower, when need operate with two people when insulating bar quantity used is many, a people in position catches insulating bar, and another people's rotating ratchet spanner, until fastening nuts.
