2, the terraced watchman's wooden clapper of whole ladder assembling is half penetrated the connection with ladder brace, and ladder brace hole and the ladder brace on terraced watchman's wooden clapper, with machinery, opened fit together perfectly, and run through locking with the high-strength insulating material rod, make terraced watchman's wooden clapper and ladder brace one integrated mass.
Therefore 3, another advantage moves conveniently, because its length is short, it is less to take up room, more is conducive to emergent accident or defect processing work.
The rectangular hollow structure section bar that the multiple chemical materials such as the utility model employing high-strength insulating resin is main material form through high temperature polymerization, pultrusion is made.The utility model insulating ladder principle is to make according to mechanics moment of inertia principle, adopts Eight characters structural entity trapezoidal, and section bar meets the mechanical structure principle, and flexing resistance is strong, is difficult for torsional deformation, firmly durable.Its material property indices is stable, section bar meets the mechanical structure principle, intensity can with iron and steel shoulder to shoulder.
The utility model also has the characteristics of giving: non-conductive, and the outward appearance novelty, elegant in appearance; Corrosion-resistant, anti-dry and decayed, anti-fading; Lightweight, convenient in carrying; Low water absorption, good flame resistance; High-strength, lightweight, absolute intensity surpasses the level of aluminium and ordinary steel.
The utility model can both can have been adjusted according to the operation field actual height when power system operating personnel ascend operation, whether chargedly can in safe controlled range, warn again the detection neighbouring device, the convenient safe or dangerous voltage of distinguishing, simple in structure, easy to use, firmly durable.The utility model can be used as the multifunctional safe ascend operation instrument that power system extensively adopts.
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is Fig. 1 contraction state structural representation.
In figure: insulating ladder watchman's wooden clapper 1, inductive probe 2, flexible draw ring 3, rubber-covered foot of ladder 4, insulation ladder brace 5.
The specific embodiment
As shown in Figure 1, the utility model is a kind of folding retractable induction type insulating ladder, mainly by insulating ladder watchman's wooden clapper 1, inductive probe 2, flexible draw ring 3, axle class steelwork, rubber-covered foot of ladder 4, insulation ladder brace 5 structures, is formed by connecting.Specifically by a plurality of insulating ladder watchman's wooden clappers 1, with a plurality of insulation ladder braces 5, be connected and form; Insulating ladder watchman's wooden clapper 1 is provided with inductive probe 2, and insulation ladder brace 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 is connected for the incomplete penetration formula with insulation ladder brace 5, and insulating ladder watchman's wooden clapper 1 is provided with insulation ladder brace hole, and insulation is provided with insulating rod in the ladder brace hole, and insulating rod runs through insulating ladder watchman's wooden clapper 1 and insulation ladder brace 5, and insulating ladder watchman's wooden clapper 1 closely is connected with insulation ladder brace 5.The insulation ladder brace hole of specifically opening with machinery on insulating ladder watchman's wooden clapper 1 is tight with 5 combinations of insulation ladder brace, and runs through locking with the high-strength insulating rod, and insulating ladder watchman's wooden clapper 1 and insulation ladder brace 5 are become one.Insulating ladder watchman's wooden clapper 1 mainly plays fixing anti-skidding effect.For anti-skidding design, terraced watchman's wooden clapper, ladder brace are half penetrated connection, and adopt the real excellent entire body of unitary circular to wear even reinforcing, and stressed rationally even, integrated connection is reliably firm.Insulation ladder brace 5 mainly plays and fixes anti-skidding effect, is anti-skidding design, and insulating ladder watchman's wooden clapper 1 is half penetrated connection with the ladder brace 5 that insulate, and adopts the real excellent entire body of unitary circular to wear even reinforcing, and stressed rationally even, integrated connection is reliably firm.
In the past, aluminum ladder in the past is connected the loose drawback of cause cracking with wooden ladder with pulling rivet or wedge to difference; Reinforce and be equipped with special high-intensity resin gripper shoe in the utility model, make the whole ladder stability that improves ladder not out of shape.Gripper shoe is located at adjacent two the insulation ladder braces 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 four sides is stressed, and anti-bending strength is good, is difficult for torsional deformation.Insulation ladder brace 5 is the ladder-shaped tubular material structure with anti-slip tank, safer and more comfortable.Non-skid band is located on the insulation ladder brace, 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 fixedly effect of ladder brace.
