Abstract

The utility model discloses an insulating ladder for a high-hung and low-used type fixed safety belt. The insulating ladder comprises a main ladder, an auxiliary ladder and fixed members, wherein the upper end of the main ladder is movably connected with the auxiliary ladder by rotating pieces; the lower parts of the rotating pieces are provided with angle adjusting members; the fixed members are arranged at the back part of the main ladder, and the lower part of the main ladder is provided with expanding and retracting belts extensible belt; cross arms of the main ladder and the auxiliary ladder are provided with the safety belt fixing rings; one fixed member is provided with a high-voltage approach warning device and an illuminating lamp. The insulating ladder disclosed by the utility model has the advantages that the upper end of the main ladder is movably connected with the auxiliary ladder, and angle adjustment for the main ladder and the auxiliary ladder is carried out by the angle adjusting members, so that the insulating ladder not only can be folded by a certain angle to be used as a herringbone ladder, but also can expand and retract to be used as a single ladder; by the fixed members, the main ladder can be prevented from loosening and sliding; further the ladder is further and firmly positioned by combination with the expanding and retracting belts; the cross arms of the main ladder and the auxiliary ladder are provided with the safety belt fixing rings, so that convenience is brought for ladder-climbing constructors to carry out operations of hanging and fixing the safety belt according to the needs, the high-hung and low-used requirements are conveniently realized and the construction safety is guaranteed.

Description

A kind of high extension is low with the fixing safety belt insulating ladder of type
Technical field
The utility model belongs to electric power overhaul tool equipment technical field, and particularly a kind of high extension is low with the fixing safety belt insulating ladder of type.
Background technology
At present, in power construction, < < electric power safety working regulation > > regulation: high-rise working safety belt is wanted " the low use of high extension ".But, current present situation is: at 35KV isolating switch, during the maintenance such as arrester, because there is no suitable fixed point, safety belt is mostly directly made a call to a knot and is carried out simple safety guarantee on framework, and maintainer will stand in and carries out service work on framework, safety belt is obviously " low extension is high to be used ", for constructor, there is very large burden at heart, supertension is fatiguability on the contrary, exist great potential safety hazard, often there is astasia to cause service kit falling from high altitude phenomenon to occur, What is more, the knot of safety belt is surprisingly shaken off, cause life security incident.
Utility model content
The utility model object is to solve the problems of the technologies described above, and provides a kind of simple in structure, and the high a kind of high extension of safety factor is low with the fixing safety belt insulating ladder of type.
To achieve these goals, the technical solution adopted in the utility model is: a kind of high extension is low with the fixing safety belt insulating ladder of type, it comprises main ladder, attached ladder and fixed component, described main terraced upper end is flexibly connected with described attached ladder by tumbler, described tumbler bottom arranges angular adjustment member, the back of described main ladder arranges described fixed component, and described main terraced bottom arranges telescopic band, and safety belt retainer ring is set on the cross-arm of described main ladder and attached ladder.
Described angular adjustment member comprises screw mandrel and the universal joint that check bolt is installed, the positive stop that described main terraced upper-end front arranges.
Described fixed component is selected the hook with chevron shaped jump ring.
High-voltage approaching alarm device and illuminating lamp are set on described fixed component.
The utility model connects attached ladder at main terraced movable upper end, and by angular adjustment member, carry out the angle adjustment of main ladder and attached ladder, both can fold and there is certain angle when double ladder use, extensible as single ladder use again, if described tumbler has braking function, arbitrarily angled hovering is set, better effects if, angular adjustment member described here adopts screw mandrel and the universal joint that check bolt is installed, be used for realizing the adjustment of different angles and fixing, the positive stop that described main terraced upper-end front arranges, when going to 180 °, limit attached ladder upset and generation danger, by the described hook with chevron shaped jump ring, can be suspended on easily on construction framework, and avoid getting loose, slippage, prevent from articulating insecure and swing, described main terraced bottom arranges telescopic band ladder is further fixedly positioning, safety belt retainer ring is set on the cross-arm of described main ladder and attached ladder, facilitate the constructor of ascending stair to carry out as required suspension and the fixing operation of safety belt, be convenient to realize high requirement of hanging low use, ensure well maintainer's safety, described high-voltage approaching alarm device and illuminating lamp are set in addition on fixed component and not only to construction safety, provide reliable guarantee, and the adaptive capacity of raising to working environment.The utility model is simple in structure, and weight only has 25 kilograms, and light and flexible is safe and practical, has good value for applications.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of high extension is low with the fixing safety belt insulating ladder of type, it comprises main terraced 1, attached terraced 2 and fixed component, described main terraced 1 upper end is flexibly connected with described attached terraced 2 by tumbler 3, described tumbler 3 bottoms arrange angular adjustment member, described angular adjustment member comprises screw mandrel 4 and the universal joint 5 that check bolt is installed, the positive stop 6 that described main terraced 1 upper-end front arranges, described main terraced 1 back arranges described fixed component 7, described fixed component 7 is selected the hook with chevron shaped jump ring, described main terraced 1 bottom arranges telescopic band 8, described main terraced 1 and attached terraced 2 cross-arm on safety belt retainer ring 9 is set, high-voltage approaching alarm device and illuminating lamp 10 are set on described hook.
The utility model connects attached ladder at main terraced movable upper end, and by angular adjustment member, carry out the angle adjustment of main ladder and attached ladder, both can fold and there is certain angle when double ladder use, extensible as single ladder use again, if described tumbler has braking function, arbitrarily angled hovering is set, better effects if, angular adjustment member described here adopts screw mandrel and the universal joint that check bolt is installed, be used for realizing the adjustment of different angles and fixing, the positive stop that described main terraced upper-end front arranges, when going to 180 °, limit attached ladder upset and generation danger, by the described hook with chevron shaped jump ring, can be suspended on easily on construction framework, and avoid getting loose, slippage, prevent from articulating insecure and swing, described main terraced bottom arranges telescopic band ladder is further fixedly positioning, safety belt retainer ring is set on the cross-arm of described main ladder and attached ladder, facilitate the constructor of ascending stair to carry out as required suspension and the fixing operation of safety belt, be convenient to realize high requirement of hanging low use, ensure well maintainer's safety, described high-voltage approaching alarm device and illuminating lamp are set in addition and not only to construction safety, provide reliable guarantee, and the adaptive capacity of raising to working environment.The utility model is simple in structure, and weight only has 25 kilograms, and light and flexible is safe and practical, has good value for applications.
