The present invention can both can adjust according to the operation field actual height when power system operating personnel ascend operation, whether charged, the convenient safe or dangerous voltage of distinguishing is simple in structure if can in safe controlled range, warn the detection neighbouring device again, easy to use, firmly durable.The present invention can be used as the multifunctional safe ascend operation instrument that power system extensively adopts.
Below in conjunction with the drawings and specific embodiments to the present invention's detailed description in addition.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is Fig. 1 contraction state structural representation.
Among the figure: insulating ladder watchman's wooden clapper 1, inductive probe 2, flexible draw ring 3, rubber-covered foot of ladder 4, insulating ladder support 5.
The specific embodiment
As shown in Figure 1, the present invention is a kind of folding retractable induction type insulating ladder, mainly is formed by connecting by insulating ladder watchman's wooden clapper 1, inductive probe 2, flexible draw ring 3, axle class steelwork, rubber-covered foot of ladder 4, insulating ladder support 5 structures.Specifically be to be connected with a plurality of insulating ladder supports 5 by a plurality of insulating ladder watchman's wooden clappers 1 to form; Insulating ladder watchman's wooden clapper 1 is provided with inductive probe 2, and insulating ladder support 5 is provided with flexible draw ring 3, and insulating ladder watchman's wooden clapper 1 bottom bottom also is provided with rubber-covered foot of ladder 4.
Insulating ladder watchman's wooden clapper 1 supports 5 for the incomplete penetration formula is connected with insulating ladder, and insulating ladder watchman's wooden clapper 1 is provided with insulating ladder support hole, and the insulating ladder support is provided with insulating rod in the hole, and insulating rod runs through insulating ladder watchman's wooden clapper 1 and insulating ladder support 5, and insulating ladder watchman's wooden clapper 1 and insulating ladder support 5 closely is connected.Specifically be tight in insulating ladder support hole and insulating ladder support 5 combinations that insulating ladder watchman's wooden clapper 1 usefulness machinery is opened, and run through locking with the high strength insulating rod, insulating ladder watchman's wooden clapper 1 and insulating ladder support 5 are become one.Insulating ladder watchman's wooden clapper 1 mainly plays fixing anti-skidding effect.Be anti-skidding design, terraced watchman's wooden clapper, terraced support are half penetrated connection, and adopt the real excellent entire body of unitary circular to wear even and reinforce, and stressed rationally even, whole connection is firmly reliable.Insulating ladder support 5 mainly plays fixes anti-skidding effect, is anti-skidding design, and insulating ladder watchman's wooden clapper 1 is half penetrated the connection with insulating ladder support 5, and adopts the real excellent entire body of unitary circular to wear even and reinforce, and stressed rationally even, whole connection is firmly reliable.
Difference in the past, in the past aluminum ladder and wooden ladder are connected the loose drawback that ftractures that causes with pulling rivet or wedge; Reinforce and be equipped with special high-intensity resin gripper shoe among the present invention, make the whole ladder stability that improves ladder not out of shape.Gripper shoe is located at adjacent two insulating ladders support 5 in ladder bottom and insulating ladder watchman's wooden clapper 1 contact position.Described insulating ladder watchman's wooden clapper 1 is for square pipe designs, and the four sides is stressed, and anti-bending strength is good, is difficult for torsional deformation.Insulating ladder support 5 is for having the laddertron equipment structure of anti-slip tank, safer and more comfortable.Non-skid band is located in the insulating ladder support, and non-skid band and anti-skidding insulation foot of ladder 4 are to be made by vulcanie, have good abrasion resistance and weatherability.Rubber-covered foot of ladder 4 mainly plays fixing anti-skidding effect, the effect of fixed ladder support.
