The structural representation of the insulating ladder that Fig. 1 provides for the utility model embodiment.
Among Fig. 1:
Support portion 1, folding part 2, joint folders 3, cross bar fixator 4, pulley 5, plastic anti-skid pad 6;
Fixed mount 21, expansion bracket 22, buckle 23.
The specific embodiment
The utility model provides a kind of insulating ladder, and it can adapt to different maintenance height, has reduced the work load of maintainer in service work, has improved overhaul efficiency.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the insulating ladder that the utility model embodiment provides, it comprises:
Support portion 1;
Folding part 2;
Connect support portion 1 and folding part 2 and have the joint folders 3 of rotation and auto-lock function.
In the insulating ladder that present embodiment provides, it comprises support portion 1 and folding part 2, support portion 1 is connected by joint folders 3 with folding part 2, when the maintenance height is low, by joint folders 3 folding part 2 is folded with respect to support portion 1, make support portion 1 and folding part 2 carry out work with the form of double ladder, when maintenance is highly higher, by joint folders 3 rotary folding portions 2, folding part 2 and support portion 1 are in the same plane, self-locking takes place in joint folders 3, and folding part 2 forms the bigger word vertical ladder of length to adapt to highly higher working environment with support portion 1.
The insulating ladder that present embodiment provides, it connects support portion 1 and folding part 2 by joint folders 3, make insulating ladder carry out work with the state of double ladder, also can carry out work with the state of a word vertical ladder, make an insulating ladder just can satisfy multiple different height requirement, need not to carry a plurality of traditional insulating ladders, make the maintainer carry, carry convenient, simplify inspection operation, reduced maintainer's work load, improved overhaul efficiency.
In order further to optimize technique scheme, in the insulating ladder that present embodiment provides, folding part 2 comprises:
The fixed mount 21 that is connected with joint folders 3;
Be arranged on the fixed mount 21, and can and locate to change the expansion bracket 22 of folding part 2 entire length with respect to fixed mount 21 slips.
In order to make insulating ladder can further adapt to the applied environment of differing heights, present embodiment preferably is set to the mode that length can change with folding part 2, wherein fixed mount 21 plays the effect of guiding and support as slide rail, expansion bracket 22 can slide at fixed mount 21, and can position at different parts and the fixed mount 21 of fixed mount 21, thereby the length of folding part 2 can be regulated, and concrete, the maximum length of folding part 2 is 1 meter.
Concrete, expansion bracket 22 positions with fixed mount 21 by the buckle 23 that is arranged on the expansion bracket 22, as shown in Figure 1.Expansion bracket 22 after it reaches the requirement position, is stuck on the fixed mount 21 buckle 23 in fixed mount 21 enterprising line slips, and expansion bracket 22 is namely realized interfixing with fixed mount 21.
Preferably, support portion 1 is the fixing word vertical ladder of length.Support portion 1 needs it to have higher fastness as main stressed support component, and therefore, 1 a choice structure comparatively stable word vertical ladder in support portion in the present embodiment is to guarantee work safety.Preferred, support portion 1 avoid movable part to the influence of its fastness, and the length of support portion 1 is 2.5 meters for the fixing word vertical ladder of length.
For technical scheme is optimized more, the insulating ladder that present embodiment provides also comprises the cross bar fixator 4 on the support end that is arranged on support portion 1, and support end is that support portion 1 is away from an end of folding part 2.Traditional insulating ladder is not provided with special slip-proofing device, and it needs personnel's supplementary insulation ladder anti-skidding, to avoid its position slip that contacts with ground and to influence service work even the maintainer is caused personal injury.The working method that this kind needs personnel to assist has been wasted the labour, has influenced operating efficiency.For fear of the problems referred to above, 1 support end being provided with that contacts with ground is parallel to the cross bar fixator 4 that ground arranges to present embodiment in the support portion, to increase the contact area on support portion 1 and ground, the probability that reduces even avoid the insulating ladder generation to slide, avoided labour's waste, liberated the surplus labor, made the work effect of insulating ladder more outstanding.
As shown in Figure 1, the movement of the insulating ladder that provides for the ease of present embodiment, the two ends of cross bar fixator 4 are respectively arranged with support rail fixator 4 and support portion 1 mobile pulley 5 on the ground, and pulley 5 can take place folding to break away from ground with respect to cross bar fixator 4.Pulley 5 is set, and the insulating ladder that makes the maintainer easily present embodiment to be provided promotes on the ground, need not carrying, makes service work more convenient, has also reduced maintainer's work load, and technique effect is further perfect.After arriving the operating position, pulley 5 being folded with respect to cross bar fixator 4, make pulley 5 and ground disengage, no longer slides in insulating ladder and ground.
Concrete, cross bar fixator 4 is fiberglass rod, and its surface is provided with plastic anti-skid pad 6, as shown in Figure 1.The insulating properties of glass fiber reinforced plastic is strong, and is corrosion-resistant, and anti-fading is in light weight, shock resistance, and magnetic permeability is splendid, can better meet the work requirements of electric power overhaul.At cross bar fixator 4 plastic anti-skid pad 6 is set, can further strengthens antifriction effect, non-skid property is stronger.
Because glass fiber reinforced plastic can just satisfy job requirement, so preferred support portion 1 and folding part 2 are respectively glass fiber reinforced plastic support portion and glass fiber reinforced plastic folding part.
In order further to increase skidproof effect, the surface of support portion 1 and folding part 2 is provided with anti-skidding striped.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
