As it is shown in figure 1, the assembly of the lifting lead wire of the present embodiment includes: leading screw 10, operation handle, pull bar, fastener 20 and Locating part 30.First end of leading screw 10 has the first connecting portion.Operation handle include handle main body and with handle main body the The screw shell of one end, screw shell is suitable with leading screw.First end of pull bar has the second connecting portion, the second end tool of pull bar There are wire auxiliary section, the first connecting portion and the second connecting portion detachably connected.The centre of fastener 20 has through hole, through hole interior Footpath is more than the external diameter of leading screw 10, and leading screw 10 is through fastener 20, and fastener 20 is arranged between operation handle and the first connecting portion, fastener The lower surface of 20 has seat slot 21 so that seat slot 21 matches with the back-to-back angle bar on high voltage iron tower, and fastener 20 can be by back-to-back Pass in the gap of angle bar.The external diameter of locating part 30 is more than the internal diameter of through hole, and leading screw 10 is through locating part 30 and makes locating part 30 Between fastener 20 and operation handle.

The technical scheme of application the present embodiment, first installs operation handle, pull bar, fastener 20 and locating part 30 to leading screw On 10, then the assembly of lifting lead wire is passed in the gap of back-to-back angle bar from bottom to top.When fastener is through back-to-back angle bar Gap after, by the seat slot on fastener 20 21 on back-to-back angle bar.Then wire is hung on pull bar, by operation handle Rotating threaded shaft 10, by lifting wire, at this moment hangs and draws the insulator of this wire to be not subjected to pulling force, thus can easily change Insulator.Application the present embodiment technical scheme efficiently solve of the prior art when lifting lead wire packaging efficiency low, Work unsafe problem.

As shown in Figure 1 to Figure 3, in the technical scheme of the present embodiment, seat slot 21 includes the first groove and the second groove, the One groove and the second groove are arranged on the opposite sides of through hole, and the groove depth of the first groove is identical with the height of back-to-back angle bar, the The groove depth of two grooves and the groove depth of the first groove are equal.Specifically, angle bar is made up of two firm materials of strip, and two firm materials of strip hang down Straight setting, the groove depth of the first groove is identical with the height on angle bar limit, and (height of the strip steel on one limit of angle bar deducts The thickness of strip steel), after so making clip seat enter angle bar, fastener fits with the other iron plate of angle bar, such fastener 20 can preferably coordinate with angle bar so that fastener 20 is more firm with the installation of angle bar.

As shown in Figure 1 to Figure 3, in the technical scheme of the present embodiment, seat slot 21 includes the 3rd groove and the 4th groove, the Three grooves and the 4th groove are arranged on the other opposite sides of through hole, and the 3rd groove and the first groove and the second groove are the most vertical Intersecting, the 4th groove and the first groove and the second groove all intersect vertically, the groove depth of the 3rd groove and the height of back-to-back angle bar Identical, the groove depth of the 4th groove and the groove depth of the 3rd groove are equal.Said structure ensure that fastener 20 can adapt to different model Angle bar, expand the versatility of the present embodiment.

As shown in Figure 1 to Figure 3, in the technical scheme of the present embodiment, fastener 20 is rectangular structure, rectangular structure Long limit is more than the gap between back-to-back angle bar, and the minor face of rectangular structure is less than the gap between back-to-back angle bar.So exist During by gap between back-to-back angle bar, can first rotate and upgrade the assembly of wire, make the minor face of fastener 20 through back-to-back The gap of angle bar, rotates and upgrades the assembly of wire the most again, makes the seat slot on the long limit of fastener 20 coordinate with angle bar.Said structure Handling ease, easy to operate.

In the technical scheme of the present embodiment, the through hole of fastener 20 has the chamfering suitable with locating part 30.Above-mentioned knot Structure makes locating part 30 preferably be combined together with fastener 20.Specifically, locating part 30 has the spiral shell matched with leading screw 10 Stricture of vagina, the lower surface of fastener 20 abuts with angle bar, and the upper surface of fastener 20 abuts against with locating part 30, thus achieves lifting and leads The suspension to wire of the assembly of line.

In the technical scheme of the present embodiment, locating part 30 also includes locating part main body and anti-abrasion structure, and anti-abrasion structure sets Put between locating part main body and fastener 20.Said structure, when operating rotatable handle, reduces between leading screw 10 and fastener 20 Frictional force.On the one hand said structure reduces exerting oneself of operator, on the other hand decreases fastener 20, locating part 30 and operation Abrasion between handle.Specifically, anti-abrasion structure is bearing, and bearing is nested on locating part 30, fastener 20 and anti-abrasion structure phase Abut.First operation handle, pull bar, fastener 20 and locating part 30 are installed to leading screw 10, then by the assembly of lifting lead wire from Pass from bottom to top in the gap of angle bar back-to-back.After fastener passes the gap of back-to-back angle bar, by the seat slot on fastener 20 21 on back-to-back angle bar.Then wire is hung on pull bar, by operation handle rotating threaded shaft 10 by lifting wire, in rotation When turning leading screw 10, locating part 30 rotates together with leading screw 10, owing to having anti-attrition part between locating part main body and fastener 20, so Frictional force between locating part main body and fastener 20 is less, and operator's is the least.When the assembly of lifting lead wire bears wire Gravity after, hang and draw the insulator of this wire to be not subjected to pulling force, thus can easily change insulator.

In the technical scheme of the present embodiment, fastener 20 is made up of aluminum alloy material.On the one hand said structure ensure that and carries The assembly rising wire can bear bigger pulling force, and specifically pulling force is between 2 to 6 tons, on the other hand the assembly of lifting lead wire Lighter.

As it is shown in figure 1, in the technical scheme of the present embodiment, the assembly of lifting lead wire also includes card-bit part, card-bit part has Have the screwed hole suitable with leading screw 10, leading screw pass card-bit part, card-bit part be positioned at operation handle away from fastener side with Manipulator's handle type is become screens.Card-bit part is tube-in-tube structure, so will not be due to the operation of mistake when operating rotatable handle Operation handle is made to deviate from leading screw 10.

In the technical scheme of the present embodiment, pull bar is made up of insulant.Said structure avoids at lifting lead wire During operator have the risk of electric shock.Specifically, the two ends of pull bar can be made of metal, such as aluminum, ferrum or rustless steel Deng.The mid portion of pull bar can be made up of the material that resistance to tension is strong.

In sum, use the technical scheme of the present embodiment to be easy to operating personnel's Self-operating, grasp with integral form Make, simplify operating procedure, remove fast with installation rate, shorten working hours, improve work efficiency, while improving safety Reduce operating personnel's labor intensity.
