Abstract
An insulated combination ladder consists of more than two steps of the ladder. One step of the ladder is used as the base seat; the top ends of the two brackets of the ladder are provided with insertion holes; the bottom ends of the two brackets of the other steps of the ladder are connected with pins; the top ends of the other steps of the ladder are provided with the insertion holes; the outside of the top part of the two brackets of each step of the ladder is fixedly provided with a connection ring. The utility model has a reasonable structure, reliable application and stable establishment; the application of the insulated combination ladder can realize the elimination of the overhead ground wire under the live line circumstance.
Description
Technical field
The utility model relates to a kind of ladder, specifically power supply industry used a kind of insulating combined ladder in work high above the ground.
Background technology
Power transmission sequence that electric company set up is through long-term operation, leads, the disconnected burst phenomenon of ground wire can happen occasionally.Particularly the power transmission sequence of 110～220KV is in operation a period of time, and its built on stilts steel strand ground wire is subjected to all-environment the influence, and a disconnected burst phenomenon can happen occasionally.Owing to there is not the desirable ladder that is used for the high-altitude climbing at present, when disconnected strand of built on stilts steel strand ground wire in the power transmission sequence of 110～220KV, occurring and needing colligation, can only be earlier to its line outage, will make somebody a mere figurehead steel strand ground wire let-down carry out colligation to the ground, disappear scarce.Adopting has a power failure disappears to lack then can influence power supply, brings loss for power supply department and electricity consumption department.
The utility model content
The purpose of this utility model is to provide a kind of insulating combined ladder, and the built on stilts steel strand ground wire in the power transmission sequence of 110～220KV occurs disconnected strand when needing colligation, it can for work high above the ground personnel climbing to its carry out charged disappear scarce.
For achieving the above object, the utility model adopts following scheme: insulating combined ladder, it is made up of the above ladder of two joints, one joint has jack as the two stands upper end of the ladder of base, all the other two stands lower ends of respectively saving ladder are connected with pin, the upper end has jack, and the two stands upper outside of every joint ladder all is fixed with a connecting ring.
When the disconnected thigh of built on stilts steel strand ground wire appearance in the power transmission sequence of 110～220KV needs colligation, the distance suitable on ground respectively accomplished fluently a unrestrained wind stake from four orientation, to unrestrained wind rope and grafting successively have been fastened as a joint ladder and other 1～2 joint ladder of base earlier, make ladder upright on the ground and be in the below of aerial earth wire, then each unrestrained wind rope is fastened respectively in each unrestrained wind stake, and then the ladder that next joint has been fastened four unrestrained wind ropes is plugged on the joint ladder that is in topmost, and four unrestrained wind ropes are fastened respectively in each unrestrained wind stake, the rest may be inferred, the required ladder that respectively saves is connected successively, arrive aerial earth wire until the top of ladder.After insulating combined ladder provided by the invention set up, the livewire work personnel put on all and force to submit, can carry out colligation to ground wire by ascending stair under the charged situation of circuit.
The utility model is rational in infrastructure, use is reliable, set up stable, its use, can be implemented under the charged situation of circuit aerial earth wire is disappeared scarce.
Description of drawings
The structure chart of one of ladder of Fig. 1 the utility model one embodiment;
Two structure chart of the ladder of Fig. 2 the utility model one embodiment;
The E of Fig. 3 Fig. 2 is to view.
The specific embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Referring to Fig. 1, the ladder 1 as base in the insulating combined ladder that the utility model provides includes support 1a and crossbeam 1d, and the syndeton of support 1a and crossbeam 1d is identical with common ladder, and the two stands 1a upper end of ladder 1 has jack 1c.The quantity of ladder 1 is a joint.
Referring to Fig. 2, other ladder 5 includes support 5a and crossbeam 5d in the insulating combined ladder that the utility model provides, the syndeton of support 5a and the crossbeam 5d also ladder with common is identical, the two stands 5a upper end of ladder 5 has jack 5c, the two stands 5a lower end of ladder 5 is connected with pin 5f, pin 5f and support 5a are one, and the quantity of ladder 5 is provided as more than two joints, generally are provided as 5～6 joints.
Referring to Fig. 1, Fig. 2, the two stands upper outside of every joint ladder all is fixed with a connecting ring 2, and the effect of connecting ring 2 is to be used to fasten unrestrained wind rope.For strengthening the bonding strength between each ladder two stands, at the bracing piece 4 that is connected with between the two stands of every ladder more than, the structure of bracing piece 4 is a stud, bracing piece 4 with the connected mode of the two stands of every ladder is: after bracing piece 4 passes the two stands of every ladder, at its two ends coupling nut 3.Connecting ring 2 also is fixed on the two stands of every joint ladder by bracing piece 4 nuts 3.
In addition, for guaranteeing the reliability after every joint ladder connects successively, the position that has jack on the support of every joint ladder has through hole, has through hole on the pin of every joint ladder.As seen from Figure 1, the position that has jack 1c on the support 1a of ladder 1 has through hole 1b, and as seen from Figure 2, the position that has jack 5c on the support 5a of ladder 5 has through hole 5b, has through hole 5e on the pin 5f of ladder 5.
In conjunction with Fig. 1, Fig. 2 as seen, after ladder 5 and ladder 1 inserted jack 1c and join by pin 5f, through hole 5e aimed at through hole 1b, pass through hole 5e and through hole 1b with bolt then and on bolt the spinning nut, can guarantee the two connection reliably.Equally, after two joint ladders 5 joined by pin 5f insertion jack 5c, through hole 5e aimed at through hole 5b, passes through hole 5e and through hole 5b and spinning nut on bolt with bolt then.The compound mode of this insulating combined ladder is: the ladder 1 of thinking base is as first segment, with a joint ladder 5 is that second joint joins with ladder 1, be that the 3rd joint joins with the ladder 5 that is second joint with another joint ladder 5 again, by that analogy, want to reach built on stilts steel strand ground wire until the total length of ladder.
Referring to Fig. 3, connecting ring 2 is for being similar to oval closed circular.
