Described gripper shoe is located at adjacent two the insulation ladder braces of ladder base and insulating ladder watchman's wooden clapper contact position.
Described insulating ladder watchman's wooden clapper is square pipe structure.
Described insulation ladder brace is the ladder-shaped tubular material structure with anti-slip tank.
Described non-skid band is located in insulation ladder brace.
The spacing of described insulation ladder brace is: 300 m m ~ 400 mm; The width of insulation ladder brace is: 35 mm; Maximum load is: 1500 N; Folding retractable induction type insulating ladder height is: 2 m ~ 5 m.
The lead-in wire of described flexible draw ring 3 is connected in insulating rod, reaches flexible multiple insulating rods run through making insulating ladder and link together.
Advantage of the present invention and beneficial effect are:
1, upper end of the present invention can be responded to and detects working site charging equipment certain safe distance time, and to electric power ascend operation field personnel one accurately to judge to keep enough safe distances, in order to avoid cause unnecessary electric shock and electrification with charging equipment;
2, the terraced watchman's wooden clapper of whole ladder assembling is half penetrated connection with ladder brace, terraced watchman's wooden clapper fits together perfectly with mechanical ladder brace hole of opening and ladder brace, and runs through locking with high-strength insulating material rod, make terraced watchman's wooden clapper and ladder brace one integrated mass.
3, another advantage moves convenient, because its length is short, it is less to take up room, is therefore more conducive to emergent accident or defect processing work.
The present invention adopts high-strength insulating resin to be that the multiple chemical materials such as main material are made through the rectangular hollow structure section bar of high temperature polymerization, pultrusion.Insulating ladder principle of the present invention makes according to mechanics moment of inertia principle, and adopt Eight characters structural entity trapezoidal, section bar meets mechanical structure principle, and flexing resistance is strong, and not easily torsional deformation is firmly durable.Its material property indices is stable, section bar meets mechanical structure principle, intensity can with iron and steel shoulder to shoulder.
The present invention also has the feature of giving: non-conductive, and novel appearance is elegant in appearance; Corrosion-resistant, resistance toly dry and decayedly, resistance to fade; Lightweight, convenient in carrying; Low water absorption, good flame resistance; High-strength, lightweight, absolute intensity exceedes the level of aluminium and ordinary steel.
The present invention both can adjust according to operation field actual height when power system operating personnel ascend operation, whether charged can warn again detection neighbouring device in safe controlled range, conveniently distinguish safe or dangerous voltage, structure is simple, 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, the present invention is described in detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
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.
Detailed description of the invention
As shown in Figure 1, the present invention is a kind of folding retractable induction type insulating ladder, is formed by connecting primarily of 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 structure.Specifically to be connected with multiple insulation ladder brace 5 by multiple insulating ladder watchman's wooden clapper 1 and to 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, is also provided with rubber-covered foot of ladder 4 bottom insulating ladder watchman's wooden clapper 1 bottom.
Insulating ladder watchman's wooden clapper 1 is with insulation ladder brace 5 for incomplete penetration formula is connected, and insulating ladder watchman's wooden clapper 1 is provided with insulation ladder brace hole, and insulation is provided with insulating rod in ladder brace hole, and insulating rod runs through insulating ladder watchman's wooden clapper 1 and insulation ladder brace 5, makes insulating ladder watchman's wooden clapper 1 and insulation ladder brace 5 compact siro spinning technology.Specifically be combined closely with insulation ladder brace 5 with the insulation ladder brace hole that machinery leaves on insulating ladder watchman's wooden clapper 1, and run through locking with high-strength insulating rod, insulating ladder watchman's wooden clapper 1 is integrated with insulation ladder brace 5 one-tenth.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 uniform force is reasonable, and integrated connection is reliably firm.Main the plaing of insulation ladder brace 5 fixes anti-skidding effect, is anti-skidding design, and insulating ladder watchman's wooden clapper 1 and insulation ladder brace 5 are half penetrated connection, and adopts the real excellent entire body of unitary circular to wear even reinforcing, and uniform force is reasonable, and integrated connection is reliably firm.
Difference in the past, aluminum ladder in the past and wooden ladder with pulling rivet or wedge be connected cause cracking loose drawback; And in the present invention, be equipped with special high-intensity resin gripper shoe reinforcing, make the whole ladder stability that improve ladder not out of shape.Gripper shoe is located at adjacent two the insulation ladder braces 5 of ladder base and insulating ladder watchman's wooden clapper 1 contact position.Described insulating ladder watchman's wooden clapper 1 designs for square pipe, and four sides is stressed, and anti-bending strength is excellent, not easily 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 in insulation ladder brace, and non-skid band and anti-skidding insulation foot of ladder 4 are made up of vulcanie, has good abrasion resistance and weatherability.Rubber-covered foot of ladder 4 mainly plays fixing anti-skidding effect, the effect of fixing ladder brace.
Whether charged inductive probe 2 described in the present invention, can warn detection neighbouring device, conveniently distinguish safe or dangerous voltage in safe controlled range.
Flexible draw ring 3 mainly plays telescopic action to insulating ladder.Run through with high-strength insulating rod, insulating ladder is played telescopic action.The lead-in wire of described flexible draw ring 3 is connected in insulating rod, reaches flexible multiple insulating rods run through making insulating ladder and link together.
The technical finesse connections such as the inductive probe that the terraced upper end that the whole ladder of the present invention is assembled into original creation is installed combine.According to national technical standard regulation, the spacing of 40 centimeters is the optimum spacing that people crosses over.Insulating ladder technical data: the height of 2 ~ 5 meters of insulating ladders is: 2 ~ 5 m; Every two insulating ladder tie distance are: 300 ~ 400 mm; Insulation ladder brace width is: 35 mm maximum loads are: 1500 N.
As shown in Figure 2, Fig. 2 is contraction state structural representation of the present invention.When not in use, folded up, use and carry very convenient.
