Abstract
The utility model discloses an insulation pulling plate of a transmission wire lifter, which is provided with a strip-shaped insulation straight plate. A pin hole for being connected with a lead screw is arranged at the upper end of the strip-shaped insulation straight plate, and a plurality of regulating holes for being connected with wire lifting hooks are arranged on the lower portion of the strip-shaped insulation straight plate. The insulation pulling plate can effectively increase safe distance, eliminates security threat to operators, can regulate the distance between the lead screw and the wire lifting hooks according to the lifting height of a wire, reduces the lifting height of the lifter, improves lifting efficiency, and also has the advantages of being simple in structure, convenient to operate, strong in practical applicability and the like.
Description
Technical field
The utility model belongs to transmission line erecting tools technical field, particularly a kind of transmission pressure line lifter insulation arm-tie.
Background technology
In the lifting operation of power system transmission line heavy in section multiple fission conductor in maintenance; The conventional method of carrying out transmission pressure lifting installation is normally stood on the cross-arm of tower bar by the operator; There is the outstanding rope of simple and easy thread-lifting hook that two leads are promoted to the height that needs by root through two root systems; And will hang rope and be bundled in respectively on the cross-arm, after treating lead is strained and fixed, untie again and take off outstanding rope.The major defect one of this method is to lean on manpower to promote two leads one by one fully, wastes time and energy, and labour intensity is big, and operating efficiency is low; The 2nd, thread-lifting hook adopts the steel plate cutting to form, and makes coarsely, causes easy damaged lead when carrying line; The 3rd, altitude hot-line operation, supporting surface is narrow and small, astasia, not only very inconvenience of operation, and seriously have potential safety hazard.At present, special-purpose line lifter is adopted in the construction that has, and this line lifter is by carrying the line suspension hook, carrying the line plate and screw mandrel is formed; The screw mandrel upper end is provided with nut, and when construction, nut places on the cross-arm of power transmission line column bar; Through rotating nut, carry the line plate, propose the up of line suspension hook through the screw mandrel drive.Though the operation of this line lifter is easier, the fail safe of carrying line than conventional method improves greatly, because screw mandrel and arm-tie all belong to metal tools, caused in the operation process safe distance shortening, personal safety is still constituted serious threat.Simultaneously, because arm-tie length is fixed, be difficult to adapt to the lifting operation of lead differing heights.
The utility model content
The purpose of the utility model be to provide a kind of can effectively eliminate safe distance that line lifter brings threat, and can adapt to the transmission pressure line lifter insulation arm-tie of the lifting operation of lead differing heights.
The technical scheme that purpose adopted that realizes the utility model is: a kind of transmission pressure line lifter insulation arm-tie; Has a strip straight plate that insulate; Its upper end is provided with the pinned hole that is used to connect screw mandrel, and the bottom is arranged and is laid with a plurality of adjustment holes that are used to connect the lead suspension hook.
The transmission pressure line lifter insulation arm-tie of the utility model can increase safe distance effectively, eliminates the security threat to operating personnel; And can regulate the distance between screw mandrel and the lead suspension hook according to the height that lead promotes, and reducing the hoisting depth of line lifter operation, raising promotes efficient; This insulation arm-tie insulation arm-tie also has advantages such as simple in structure, easy to operate, practical.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the user mode sketch map of the utility model.
Embodiment
Referring to Fig. 1; The transmission pressure line lifter of the utility model insulation arm-tie has a strip of processing with the insulating sheet material straight plate 1 that insulate, and can make shape insulating tape between screw mandrel 4 and the lead suspension hook 5 of wire lifting device; Increase safe distance effectively, eliminate security threat operating personnel.Be provided with pinned hole 3 in this upper end of insulating straight plate 1, be used for wearing pin and be connected with the screw mandrel 4 of wire lifting device.The insulate bottom of straight plate 1 is arranged and to be laid with a plurality of adjustment holes 2; Be used for and being connected of the lead suspension hook 5 of wire lifting device; And can regulate the distance between said screw mandrel 4 and the lead suspension hook 5 according to the height that lead promotes, and reduce the hoisting depth of line lifter operation, improve lifting efficient.
