Abstract

The utility model relates to a portable insulator replacing tool. The portable insulator replacing tool comprises an upper hook which is used for being connected with a cross arm. A lifting device is arranged at the lower part of the upper hook. A ladder is arranged on the lifting end of the lifting device. A lower hook which is used for being connected with a cable is arranged at the lower part of the ladder. According to the utility model, the tool has the advantages of simple and reasonable structure and convenient implementation and promotion; when the tool is used, the upper hook is hung on the cross arm, and the lower hook is hung on the cable which needs insulator replacing; an operator climbs on the ladder; through the lifting of the lifting device, the distance between the cross arm and the cable is shortened, and the insulator is not under stress; the operator completes insulator replacing on the ladder; the problems that the insulator is easily trampled and the operator easily falls off, which are caused due to the fact that the operator has to step on the insulator in the past, are avoided; and the portable insulator replacing tool is labor-saving and time-saving, can protect the insulator and can improve the safety coefficient.

Description

A kind of portable is changed insulator instrument
Technical field
The utility model relates to the instrument that a kind of power industry is used, and relates in particular to a kind of portable and changes insulator instrument.
Background technology
Insulator is a kind of special insulation control, can in overhead transmission line, play an important role.It is used for supporting and fixedly bus and energized conductor and make between energized conductor or conductor and the earth between have enough distances and insulation, there is enough electric insulation intensity and moisture-resistance.In actual use, insulator can be used or outer thereby damage because of long-time, in order to guarantee electric power regular supply, just requires to change in time insulator.During present replacing insulator, be all that people directly scrunches on insulator, be easy to like this insulator to trample on, and insulator be more sliding, people is easy to landing from insulator and gets injured by a fall, and has very large potential safety hazard.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of simple in structure, easy to use, save trouble and labor is provided, the portable that can protect insulator can improve coefficient of safety changes insulator instrument.
The purpose of this utility model is achieved in that a kind of portable replacing insulator instrument, it comprises the upper hook for being connected with cross-arm, the bottom of upper hook is provided with lifting device, and the lifting end of lifting device is provided with cat ladder, and the bottom of cat ladder is provided with the lower draw-bar for being connected with cable.
Described lifting device adopts bottle gouard moved by hands, and the upper end of cat ladder is connected with the lifting end of the drag-line of bottle gouard moved by hands.
Described upper hook and lower draw-bar all adopt insulating hanger.
Described cat ladder is comprised of the mobile jib being connected with lifting device and the stull that is evenly arranged on mobile jib both sides.
The utlity model has following positive effect: the utility model comprises upper hook, lifting device, cat ladder and the lower draw-bar from top to bottom connecting successively, simple and reasonable, be convenient to implement and promote; In use; upper hook is hung on cross-arm; lower draw-bar is hung on the cable that will change insulator; operating personnel, by climbing on cat ladder, promote by lifting device, and then shorten the distance of cross-arm and cable; insulator is not stressed; operating personnel complete the replacing of insulator on cat ladder, and then have avoided traditional people will step down in problem on insulator, the problem includes: the problem of easily insulator being trampled on and easily being fallen has advantages of save trouble and labor, can protect insulator can improve coefficient of safety again.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of portable of the utility model is changed insulator instrument.
In figure: 1, upper hook 2, lifting device 3, cat ladder 4, lower draw-bar 5, drag-line.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment 1
As shown in Figure 1, change an insulator instrument, it comprises the upper hook 1 for being connected with cross-arm, and the bottom of upper hook 1 is provided with lifting device 2, the lifting end of lifting device 2 is provided with cat ladder 3, and the bottom of cat ladder 3 is provided with the lower draw-bar 4 for being connected with cable.
The utility model comprises upper hook, lifting device, cat ladder and the lower draw-bar from top to bottom connecting successively, simple and reasonable, is convenient to implement and promote; In use; upper hook is hung on cross-arm; lower draw-bar is hung on the cable that will change insulator; operating personnel, by climbing on cat ladder, promote by lifting device, and then shorten the distance of cross-arm and cable; insulator is not stressed; operating personnel complete the replacing of insulator on cat ladder, and then have avoided traditional people will step down in problem on insulator, the problem includes: the problem of easily insulator being trampled on and easily being fallen has advantages of save trouble and labor, can protect insulator can improve coefficient of safety again.
Embodiment 2
As shown in Figure 1, change an insulator instrument, it comprises the upper hook 1 for being connected with cross-arm, and the bottom of upper hook 1 is provided with lifting device 2, the lifting end of lifting device 2 is provided with cat ladder 3, and the bottom of cat ladder 3 is provided with the lower draw-bar 4 for being connected with cable.
Described lifting device 2 adopts bottle gouard moved by hands, and the upper end of cat ladder 3 is connected with the lifting end of the drag-line 5 of lifting device 2.
Described upper hook 1 and lower draw-bar 4 all adopt insulating hanger.
Described cat ladder 3 is comprised of the mobile jib being connected with lifting device 2 and the stull that is evenly arranged on mobile jib both sides.
The utility model comprises upper hook, lifting device, cat ladder and the lower draw-bar from top to bottom connecting successively, simple and reasonable, is convenient to implement and promote; In use; upper hook is hung on cross-arm; lower draw-bar is hung on the cable that will change insulator; operating personnel, by climbing on cat ladder, promote by lifting device, and then shorten the distance of cross-arm and cable; insulator is not stressed; operating personnel complete the replacing of insulator on cat ladder, and then have avoided traditional people will step down in problem on insulator, the problem includes: the problem of easily insulator being trampled on and easily being fallen has advantages of save trouble and labor, can protect insulator can improve coefficient of safety again.
