Abstract

The utility model relates to a hand tool. After a rear clamp in the tool is used for clamping a right-angle hanging plate with a tower head-shaped end, a front clamp in the tool is used for clamping conductive wires. Moreover, wire tension borne by an insulator string is transmitted to a special insulating tool through a wire tightening screw lever and an insulating pull plate. Thus, the purpose of replacing poor insulators is achieved. The utility model has the advantages of portable and easy operation and carrying. In addition, the utility model not only can replace tension supporting string poor insulators on angle towers with various angles in 66KV circuits with power, but also can replace tension supporting string poor insulators connected by tension supporting clamps in various types in 66KV circuits with power.

Description

Change insulator charged power tool

The utility model relates to a kind of hand tools, the insulator charged power tool of particularly a kind of replacing.

For a long time, China is on 66 kilovolt, and live line working has two problems not solve, and the firstth, the strain insulator-string poor insulator on the wide-angle angle tower is changed difficult.The secondth, adopt the strain insulator-string poor insulator of compression-type wire clamp to change difficulty on the circuit, changed poor insulator all must have a power failure and carry out in the past, so not only the economic loss of Ting Dianing is very big, do not guarantee simultaneously the reliability of power supply yet, therefore, for addressing the above problem, this is practical to have designed a kind of tools for live working.The operation simple in structure, light, easy of this cover tools for live working with carry, it can charged for replacement 66 kilovolt in the strain insulator-string poor insulator that connects of the strain clamp of strain insulator-string poor insulator on the angle tower of various angles and the various types in charged for replacement 66 kilovolt.

The purpose of this utility model provides the insulator charged power tool of a kind of replacing.

The utility model is achieved in that this cover special isolation tool work principle is the back card that utilizes in the instrument, after blocking tower head end right angle link plate, utilize preceding card in the instrument, block lead, transfer on the special isolation instrument by stringing leading screw and the wire tension that the insulation arm-tie is born insulator string again, and reach the purpose of changing poor insulator.

This cover special isolation instrument is whole for holding in the palm insulator frame form, is made of preceding card, stringing leading screw, insulation arm-tie, insulator pressure pin, the back several critical pieces of card.Its structure assembling form is, the stringing screw is positioned on the card of back, stringing leading screw spiral end connects by screw and back card, and the link of leading screw connects with the insulation arm-tie with bolt, the insulation arm-tie other end stretches in the preceding OK a karaoke club sleeve-board hole locatees with bolt, thereby has realized the connection of back card, stringing leading screw, insulation arm-tie, preceding card.The insulator pressure pin is then connected by the front and back supporting plate that is separately fixed at screw on the front and rear card.

The utility model compared with prior art, have operation simple in structure, light, easy and carry, and main be it can charged for replacement 66 kilovolt in the strain insulator-string poor insulator that connects of the strain clamp of strain insulator-string poor insulator on the angle tower of various angles and the various types in charged for replacement 66 kilovolt.So not only reduce the economic loss that has a power failure and brought, guaranteed the reliability of power supply simultaneously.

Concrete structure of the present utility model and embodiment are provided by the following drawings;

Fig. 1 is a general structure schematic diagram of the present utility model;

Fig. 2 is that the A of Fig. 1 is to view;

Fig. 3 is that the B of Fig. 1 is to view;

Fig. 4 is a working state schematic representation of the present utility model.

Below in conjunction with accompanying drawing concrete structure of the present utility model and embodiment are done with further instruction.

See shown in Fig. 1,2,3,4: it is whole for holder insulator frame form to change insulator charged power tool, is made of parts such as preceding card, stringing leading screw 9, insulation arm-tie 4, insulator pressure pin 5, back cards.Its structure assembling form is, stringing screw 10 is positioned on the catcher 2 of back card 1, stringing leading screw 9 spiral ends are connected by the catcher 2 of screw 10 with back card 1, the link of leading screw 9 is connected with insulation arm-tie 4 by bolt 12, use bolt 17 location before insulation arm-tie 4 other ends stretch in OK a karaoke club plate 6 trepannings, thereby realized the connection of back card 1, stringing leading screw 10, insulation arm-tie 4, preceding card.Insulator pressure pin 5 then is separately fixed on the front and back supporting plate 13,11 on the front and rear card by screw.

Critical component in this cover special isolation instrument is preceding card and back card, and two parts are manufactured by high-strength aluminum alloy.

On back card 1, be fixedly connected, reach the change angle by changing back card 1 with the connecting portion of taking over 2, to adapt to the purpose of on the different angles tower, using by bolt shaft 21 and catcher 2.

Preceding card is designed to the clip mechanism by the bolt shaft connection by many combinations such as arm-tie 6, fishplate bar 14, connecting rod 7, support plate 8, jaws 16.Its structure assembling form is: arm-tie 6, connecting rod 7, fishplate bar 14 link together by bolt shaft 20, and arm-tie 6 can drivening rod 7 orientation on fishplate bar 14 move by bolt shaft 20, and is spacing by fishplate bar 14 chutes.Connecting rod 7 other ends are connected with support plate 8 with bolt shaft 15, support plate 8 then is riveted on the fishplate bar 14 with rivet 19 and (can rotates), two connecting rods 7 have so just been formed, two support plates 8 are two triangles on common base with a

fishplate bar

14, and 16 of two jaws are with

bolt shaft

18 and 8 corresponding the linking together of two support plates.Move on fishplate bar by arm-tie 6 drivening rods 7, two triangular angles are changed, close thereby drive jaw 16 switchings.To overlap specific purpose tool during work is put on the tower head right angle link plate that on the insulator string the back card on the instrument is stuck in iron tower, preceding card clip is on lead, pull ratchet spanner 3 (ratchet spanner 3 be positioned at the screw 10 of catcher on 2 be connected) then, ratchet spanner 3 drives screw 10 and rotates, and itself and the leading screw 9 that screws are produced an axial force, this axial force passes on the preceding OK a karaoke club plate 6 by insulation arm-tie 4, again by preceding OK a karaoke club plate 6 through bolt shaft 20 and connecting rod 7 responsive to axial force to support plate 8, this axial force produces a very big normal pressure (leverage) by 8 pairs of jaws 16 that link together with support plate 8 of support plate again, the friction yarn number of this normal pressure and jaw 16 and lead produces one and is subjected to the opposite frictional force of force direction with lead, thereby reaches the order ground that blocks lead.
