Description
Technical field
The present invention relates to a kind of anti-skidding race type rope ladder.
Background technology
In Equipotential live working, live line working personnel often can utilize insulated flexible ladder to enter electric field to carry out hotline maintenance to lead wire and earth wire in transmission line etc.For ensureing insulated flexible ladder and lead wire and earth wire reliable link, thus there is the transition utensil that rope ladder is connected with lead wire and earth wire---terraced head.Be connected by terraced head between rope ladder with wire, rope ladder method is implemented.But because transmission line wire all exists the vertical arc without degree, after rope ladder head is hung on wire, be no matter wire hang down arc impact or climb in rope ladder process operating personnel, all can there is displacement in various degree in rope ladder, when vertical arc is larger, may occur when operating personnel climbs up software top and actual job point at a distance of situation excessively far away, now need again newly to move to suitable job position by nose heave for ladder.When ramp head, the position of rope ladder is not easily fixed, and rope ladder is easily moved, and so just there is great potential safety hazard, and the operating efficiency of operating personnel also will reduce greatly.
Summary of the invention
The present invention is for avoiding the weak point that exists in above-mentioned prior art, providing a kind of anti-skidding race type rope ladder, with make rope ladder can locked in fixing service position, improve operating efficiency and security reliability.
The present invention be technical solution problem by the following technical solutions.
Anti-skidding race type rope ladder, its design feature is, comprises wire guide pulley wheels, anti-skidding race chock, rope ladder main body, operation backrest and rope ladder hanging point; Described wire guide pulley wheels is fixed on the first end of described rope ladder main body, and described rope ladder hanging point is fixed on the second end of described rope ladder main body; In described rope ladder main body, between described first end and described second end, be provided with described operation backrest; On the first end of described rope ladder main body, a described wire guide pulley wheels is respectively set in the both sides of described rope ladder main body; The edge part of described wire guide pulley wheels, is provided with multiple circular holes of wire guide pulley wheels described in the axial penetration along described wire guide pulley wheels;
In described rope ladder main body, the position near described wire guide pulley wheels is provided with the anti-skidding race chock with spring, and described chock can be inserted within described circular hole.
The design feature of anti-skidding race type rope ladder of the present invention is also:
Described multiple circular hole is evenly distributed in the edge part of described wire guide pulley wheels along the circumference of described wire guide pulley wheels.
The edge part of described wire guide pulley wheels is provided with six described circular holes.
Compared with the prior art, beneficial effect of the present invention is embodied in:
Anti-skidding race type rope ladder of the present invention, comprises wire guide pulley wheels, anti-skidding race chock, rope ladder main body, operation backrest and rope ladder hanging point.Wire guide pulley wheels is led for rope ladder head device edge when not fixing, ground wire moves freely; Anti-skidding race chock is used for rope ladder head to be accurately positioned setting, and arc generation is sliding runs phenomenon because wire hangs down to prevent terraced head; Rope ladder main body forms the main part of rope ladder; Operation backrest is used for operating personnel to carry out when carrying out work supporting and protecting; Play when rope ladder hanging point is used for operation and hang rope ladder.Anti-skidding race type rope ladder of the present invention, solve the factors such as arc of hanging down due to transmission line to cause and to climb operating personnel that rope ladder head in rope ladder process is sliding to run away from this difficult problem of actual job place, not only there is great potential safety hazard waste time and energy simultaneously because operating personnel carries out being shifted on rope ladder head, therefore the application of this device effectively saves the actual job time, decrease labour intensity, improve operating efficiency.
Anti-skidding race type rope ladder of the present invention, for realizing the accurate location of terraced head on wire, anti-on-slip is run, have rope ladder can be made can be fixed on wire, solve rope ladder easily sliding run affect operation problem, decrease labour intensity, improve the advantages such as operating efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of anti-skidding race type rope ladder of the present invention.
Schematic diagram when Fig. 2 is the locking of anti-skidding race type rope ladder of the present invention.
Label in Fig. 1-2 is: 1 wire guide pulley wheels, 2 circular holes, 3 rope ladder main bodys, 4 operation backrests, 5 rope ladder hanging points, 6 chocks.
Below by way of embodiment, and the invention will be further described by reference to the accompanying drawings.
Embodiment
See Fig. 1 and Fig. 2, anti-skidding race type rope ladder of the present invention, comprises wire guide pulley wheels 1, anti-skidding race chock 6, rope ladder main body 3, operation backrest 4 and rope ladder hanging point 5; Described wire guide pulley wheels 1 is fixed on the first end of described rope ladder main body 3, and described rope ladder hanging point 5 is fixed on the second end of described rope ladder main body 3; In described rope ladder main body 3, between described first end and described second end, be provided with described operation backrest 4; On the first end of described rope ladder main body 3, a described wire guide pulley wheels 1 is respectively set in the both sides of described rope ladder main body 3; The edge part of described wire guide pulley wheels 1, is provided with multiple circular holes 2 of wire guide pulley wheels 1 described in the axial penetration along described wire guide pulley wheels 1;
In described rope ladder main body 3, the position near described wire guide pulley wheels 1 is provided with the anti-skidding race chock 6 with spring, and described chock 6 can be inserted within described circular hole 2.
Described multiple circular hole 2 is evenly distributed in the edge part of described wire guide pulley wheels 1 along the circumference of described wire guide pulley wheels 1.
