Abstract

The invention discloses a live line working tool, and particularly relates to an adjustable insulating ladder. The adjustable insulating ladder comprises a herringbone insulating ladder body (1), four supporting legs (2) are arranged on the insulating ladder body (1), the lower portions of the four supporting legs (2) are connected with auxiliary legs (3), the lower portions of the supporting legs (2) are provided with fixing screw holes (21), the upper portion of each auxiliary leg (3) is provided with at least two sets of adjusting screw holes (31), and each supporting leg (2) and the corresponding auxiliary leg (3) are mutually fixed through the method that a bolt penetrates through the fixing screw holes (21) and at least one set of adjusting screw holes (31). The adjustable insulating ladder has the advantages that the adjustable insulating ladder can be normally used on the flat ground and can also be normally arranged on a slope or a side slope in an erecting mode according to the terrain by adjusting the auxiliary legs, the times of power failures are effectively reduced, the power supply reliability is greatly improved, and in addition, the adjustable insulating ladder is simple in design, easy to operate, flexible, convenient to carry and high in applicability.

Description

A kind of adjustable, insulating ladder
Technical field
The present invention relates to a kind of tools for live working, be specifically related to a kind of adjustable, insulating ladder.
Background technology
Along with construction and the development of electrical network, live line working has become the important means of provide and deliver electric testing of equipment, maintenance, transformation, for the safe and reliable operation of electric power system has been brought into play very important effect with increasing economic efficiency.The development of live line working level, obtain a large amount of popularizations in overhead insulation bucket arm vehicle, qualified insulation clothing, premium insulation Work tool Chang Zuoye, these high-tech products have not only improved the efficiency of work, have also reduced operating personnel's labour intensity, have increased the fail safe of live line working.
But, for distribution network live line work, also have at present many local Operation Vans to arrive, insulated platform also can't be installed.If adopt interruption maintenance can affect client's electricity consumption, even power failure range is excessive, affects economic benefit and social benefit.Can only adopt indirect operating at present, such as utilizing insulating ladder or double ladder operation, in job sites such as slope or side slopes, conventional insulating ladder is excessive and can't be solid and reliable due to the gradient, operating personnel's safety can not get abundant guarantee, causes carrying out live line working.
Summary of the invention
The object of the present invention is to provide a kind of adjustable, insulating ladder, solved at present for the insulator of electrical network can not be on slope or side slope the fixing problem of safety.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: a kind of adjustable, insulating ladder, comprise lambdoid insulation, four legs are arranged on it, described four underfooting all are connected with secondary pin, the bottom of leg is provided with fixing threaded hole, and the top of described secondary pin is provided with at least two groups and regulates screws, and a group of pass in fixing threaded hole and at least two groups adjusting screw by bolt of leg and secondary pin interfixes.
Further technical scheme is, the bottom of described secondary pin is provided with the insulation footmuff.
Further technical scheme is, between the leg of herringbone both sides, is connected with insulating tape.
Further technical scheme is, the wide 0.4m of described leg, long 4m, the long 1.5m of secondary pin, the aperture 8mm of described fixing threaded hole and adjusting screw.
Compared with prior art, the invention has the beneficial effects as follows: can not only on level land, normally use, can also on slope or side slope, according to landform, regulate secondary pin normally sets up, effectively reduced frequency of power cut, greatly improve power supply reliability, in addition adjustable, insulating ladder simplicity of design, easy operating, flexible, be easy to carry, applicability is high.
The accompanying drawing explanation
The structural representation that Fig. 1 is insulating ladder in the present invention.
Fig. 2 is the end view of insulating ladder in the present invention in Fig. 1.
The structural representation that Fig. 3 is secondary pin in the present invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1, Fig. 2 and Fig. 3 show an embodiment of a kind of adjustable, insulating ladder of the present invention: a kind of adjustable, insulating ladder, comprise lambdoid insulating ladder 1, four legs 2 are arranged on it, described four legs all are connected with secondary pin 3 for 2 times, the bottom of leg 2 is provided with fixing threaded hole 21, the top of described secondary pin 3 is provided with at least two groups and regulates screws 31, and a group of pass in fixing threaded hole 21 and at least two groups adjusting screw 31 by bolt of leg 2 and secondary pin 3 interfixes.
A kind of adjustable, insulating ladder preferred embodiment according to the present invention, the bottom of described secondary pin 3 is provided with insulation footmuff 4, and because this ladder is for electric network operation, insulating gum cover 4 can more effective assurance insulation effect.
A kind of adjustable, insulating ladder preferred embodiment according to the present invention, be connected with insulating tape 5 between the leg 2 of herringbone both sides, insulating tape 5 can effectively guarantee that lambdoid insulating ladder can not open to both sides because of skidding, and avoids the staff to drop from above.
Another preferred embodiment of a kind of adjustable, insulating ladder according to the present invention, the wide 0.4m of described leg 2, long 4m, the long 1.5m of secondary pin 3, the aperture 8mm of described fixing threaded hole 21 and adjusting screw 31.

Claims (4)
