Abstract

The utility model discloses an adjustable insulating ladder. The adjustable insulating ladder comprises a lambdoidal insulating ladder (1) on which four supporting legs (2) are arranged, the four supporting legs (2) are connected with assistant legs (3), the lower parts of the supporting legs (2) are provided with fixed screw holes (21), the upper parts of the assistant legs (3) are provided with at least two sets of adjusting screw holes (31), and the supporting legs (2) and the assistant legs (3) penetrate through the fixed screw holes (21) through bolts and are fixed to one set of the at least two sets of adjusting screw holes (31) in a mutual manner. The adjustable insulating ladder has the functions that the ladder can not only be normally used on flat ground, but can also be normally erected on a slope or a side slope by adjusting the assistant legs according to the terrain, thereby effectively reducing the number of times of power failure, greatly improving reliability of power supply, and in addition, the adjustable insulating ladder is simple in design, easy to operate, flexible and mobile, convenient to carry, and high in applicability.

Description

A kind of adjustable, insulating ladder
Technical field
The utility model relates to a kind of tools for live working, is 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, in overhead insulation bucket arm vehicle, qualified insulation clothing, premium insulation Work tool Chang Zuoye, obtain a large amount of popularizations, 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 cannot 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 because the gradient is excessive and cannot be solid and reliable, operating personnel's safety can not get abundant guarantee, causes carrying out live line working.
Utility model content
The purpose of this utility model is to provide a kind of adjustable, insulating ladder, solved at present for the insulator of electrical network can not be in slope or side slope safety fixing problem.
For solving above-mentioned technical problem, the utility model is by the following technical solutions: a kind of adjustable, insulating ladder, comprise lambdoid insulation, on it, there are four legs, described four underfooting are all 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 screw, and leg and secondary pin pass fixing threaded hole by bolt and at least two groups regulate one group in screw to interfix.
Further technical scheme is, the bottom of described secondary pin is provided with 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 beneficial effects of the utility model are: can not only on level land, normally use, can also in slope or side slope, according to landform, regulate secondary pin normally to set 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.
Accompanying drawing explanation
Fig. 1 is the structural representation of insulating ladder in the utility model.
Fig. 2 is the end view of insulating ladder in the utility model in Fig. 1.
Fig. 3 is the structural representation of secondary pin in the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Fig. 1, Fig. 2 and Fig. 3 show an embodiment of a kind of adjustable, insulating ladder of the utility model: a kind of adjustable, insulating ladder, comprise lambdoid insulating ladder 1, on it, there are four legs 2, described four legs are all 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 screw 31, and leg 2 and secondary pin 3 pass fixing threaded hole 21 by bolt and at least two groups regulate one group in screw 31 to interfix.
According to a preferred embodiment of a kind of adjustable, insulating ladder of the utility model, 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.
According to a preferred embodiment of a kind of adjustable, insulating ladder of the utility model, between the leg 2 of herringbone both sides, be connected with insulating tape 5, insulating tape 5 can effectively guarantee that lambdoid insulating ladder can not open to both sides because of skidding, and avoids staff to drop from above.
According to another preferred embodiment of a kind of adjustable, insulating ladder of the utility model, 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.
