Abstract
The utility model relates to a lap resistance wire lifting device which comprises two supporting seats. The utility model is characterized in that: the two supporting seats are connected with each other through a leading screw element with adjustable length; vertical leading screws are respectively arranged on the two supporting seat; the lower end of the vertical leading screws can be connected with insulating suspenders; the upper part of the vertical leading screws is connected with leading screw sleeves arranged on the upper part of a pedestal. The utility model has the advantages that: a live wire can be lifted up by integrated use of the utility model and a six splitting wire hook; chain insulators can be exchanged without the need of power cut; the live-wire work of compact lines is made easy and simple; the safety factor is high as well.
Description
Technical field
The utility model relates to a kind of instrument to the live wire operation, particularly a kind of tower head lead lifting device.
Background technology
In compact line, the division number of lead and conventional line division number are different, usually adopt six divisions to arrange, promptly every six roots of sensation sub-conductor is separately fixed at by cylindrical arrangement in six through holes of six yoke plates, and the insulator string through being connected with six yoke plates is fixed on the tower bar again.Because the safety operation of compact line distance is smaller, in the regional 500kv compact line of particularly high elevation, at following earth potential of height above sea level 1000m and equal potential working minimum safe distance relatively is 3.2m only, and alternate minimum safe distance only is 4.6m during equal potential working; At height above sea level 1000m and above earth potential and equal potential working minimum safe distance relatively is 3.4m only, and alternate minimum safe distance only is 5.0m during equal potential working.And be damaged when need changing when insulator string, all be that the operating type of taking to have a power failure is changed at present usually, though safe, make troubles for people's the life and the production of enterprise.
In order also to overhaul, change operation under situation about not having a power failure, the present inventor has invented two kinds of instruments, and a kind of is the six-multiple conductor hook that can carry out live line working, and another kind is a lead lifting device of the present utility model.During operation the utility model lead lifting device is fixed on the cross-arm of tower bar, be connected with the six-multiple conductor hook through the insulation suspension rod again, can under electriferous state, hold lead with the six-multiple conductor hook, the weight of lead is transferred on these two instruments, just can have been changed the operation of insulator string.
The utility model content
Technical problem to be solved in the utility model provides a kind of and the six-multiple conductor hook is used the tower head lead lifting device that lead can be mentioned.
The utility model solves the problems of the technologies described above with following technical scheme: two supporting seats are connected by the lead screw assembly of adjustable length, on two supporting seats the vertical hair thick stick is housed respectively, the lower end of vertical hair thick stick can be connected with insulated hanging pole, and top is connected with the leading screw sleeve that places the pedestal top.
The lead screw assembly of two supporting seats of described connection is made of leading screw sleeve, two horizontal hair thick sticks and lengthening rod member and bolt, two horizontal hair thick sticks are connected with the two ends of leading screw sleeve respectively, the other end of two horizontal hair thick sticks is connected with the lengthening rod member respectively again, is connected by bolt between lengthening rod member and the supporting seat.
The bottom of described two supporting seats has the draw-in groove that pedestal can be stuck on the tower bar cross-arm master material.
Have through hole on described two supporting seats, the vertical hair thick stick places through hole.
The utility model tower head lead lifting device and six-multiple conductor hook are used, and electrified wire can be mentioned, and need not to have a power failure and just can change the operation of insulator string, and compact line live line working work is become simply, easily, and coefficient of safety is also high.
Description of drawings
Fig. 1 is the structural representation of the utility model tower head lead lifting device.
Embodiment
As shown in Figure 1, there are the externally threaded horizontal hair thick stick 3 of relative trend and lengthening rod member 5 to be connected by the leading screw sleeve 2 of band handle 1, two between two supporting seats 6 with the lead screw assembly that bolt 4 constitutes, two horizontal hair thick sticks 3 are connected with the two ends of female leading screw sleeve 2 respectively, the other end of two horizontal hair thick sticks 3 is connected with lengthening rod member 5 respectively again, is connected by bolt 4 between lengthening rod member 5 and the supporting seat 6; Have through hole 11 on two supporting seats 6, be equipped with in the through hole and establish externally threaded vertical hair thick stick 7, there is the bolt 12 that can connect insulated hanging pole the lower end of vertical hair thick stick, top is connected with the leading screw sleeve 8 of the band handle 9 that places the pedestal top, the leading screw sleeve has the internal thread that is complementary with vertical hair thick stick external screw thread, the bottom that 10, two supporting seats of packing ring are housed between leading screw sleeve 8 and the supporting seat 6 has draw-in groove 13.
During use, the draw-in groove of supporting seat is stuck on the tower bar cross-arm master material, then turning handle 1 length of regulating lead screw assembly, two supporting seats are tightened up the tower material of tower head both sides, so that when promoting lead, the tower material of tower head only need bear vertical power, horizontal pull just thus device bear.Change, when overhauling the operation of insulator string, lower end at the vertical hair bar connects insulated hanging pole with bolt 12, the other end of insulated hanging pole is connected with the six-multiple conductor hook, because the action of gravity of insulated hanging pole and six-multiple conductor hook, with vertical hair thick stick tension location, this moment turning handle 9, leading screw sleeve 8 along continuous straight runs are rotated, the vertical hair thick stick just moves up and down along the internal thread of leading screw sleeve 8, and the six-multiple conductor hook that is connected with insulated hanging pole also moves up and down simultaneously, thereby also can hook the lead on six yoke plates under the charged situation and they are being held up, the weight of lead is transferred on these two instruments, and the insulator string that connects six yoke plates just can take off and overhauls, change, thereby reach the purpose that insulator is changed in live line working.
