Description
Technical field:
The present invention relates to a kind of power system high-altitude maintenance device, particularly relate to a kind of telescopic high-altitude maintenance insulating ladder.
Background technology:
Some GIS transformer stations and transformation, the newly transforming plant primary equipment that puts into operation are arranged the compactest, limited by site contour, during service work with surrounding charging equipment safe distance not, cause maintenance lift truck and cannot bring challenge near repair apparatus to carrying out smoothly of high-altitude maintenance work.At present, carry out work high above the ground and typically use extended type double ladder or build scaffold, use double ladder time, ladder can only ride on equipment framework, eminence plant maintenance less than；Additionally equipment itself and insulation are supported not allow to hang seat belt, and during work, seat belt hangs nowhere, belongs to and operates against regulations；And build scaffold and can solve narrow and small scene and cannot use a difficult problem for lift truck, but there is also many problems, such as: build loaded down with trivial details, difficult, prepare the time-consuming problem such as long.
Summary of the invention:
The technical problem to be solved is: overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, easy to use, can distance be flexible and the telescopic high-altitude maintenance insulating ladder that acts freely.
The technical scheme is that a kind of telescopic high-altitude maintenance insulating ladder, containing four telescopic single poles, described four telescopic single poles connect into square extension ladder by cross bar, it is provided with described cross bar on each pole body of described four telescopic single poles, each described cross bar is provided with fixed cover with the junction of described four telescopic single poles, and described four telescopic single poles are respectively provided with an inclined support bar；Described four telescopic single poles are made by reinforced plastic glass fibre material.
Described fixed cover is rubber adapter sleeve or screw insulator set.Described inclined support bar upper end is connected by anchor ear is movable with described four telescopic single poles, and, described inclined support bar lower end is provided with leg.Being provided with middle studdle between described inclined support bar and described four telescopic single poles, described middle studdle two ends are respectively by anchor ear and described inclined support bar with described four telescopic single poles are movable is connected.It is provided with tool shelf on described cross bar, described tool shelf is provided with fixed mechanism, it is possible to place and fix maintenance tool.
The invention has the beneficial effects as follows:
1, raw material based on the present invention uses reinforced plastic glass fibre material, the advantage that quality is light, tough and tensile firmly, insulation effect is good is had than the pitch tube used in the past, use this ladder to decrease labor intensity, shorten the activity duration, improve the safety coefficient of on-the-spot work high above the ground.
2, list of the present invention set cost is 30,000 yuan, and compare electric up-down ladder 70,000 yuan, 50,000 yuan of scaffold, and configuration 3 this platform of set can save 6-12 ten thousand yuan.
3, the telescopic single pole of the present invention is connected by cross bar, and blend rubber sleeve pipe is reinforced, it is possible to dismounting, it is simple to make and transport, and reduces use cost.
4, the present invention is provided with bearing diagonal, adds the steadiness of whole ladder, and additionally bearing diagonal is connected with telescopic single pole by anchor ear, easy accessibility.
5, present configuration simple, easy to use, can distance flexible and act freely, it is applied widely, not only applies narrow and small operation field, can substitute for the scene needing lift truck work completely, it is easy to popularization, has good economic benefit.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of telescopic high-altitude maintenance insulating ladder；
Fig. 2 is the top view of telescopic high-altitude maintenance insulating ladder shown in Fig. 1.
Detailed description of the invention:
Embodiment: see Fig. 1 and Fig. 2, in figure, 1-inclined support bar, 2-middle studdle, 3-anchor ear, 4-cross bar, 5-fixed cover, the telescopic single pole of 6-.
Telescopic high-altitude maintenance insulating ladder contains four telescopic single pole 6(and uses fishing rod telescopic structure, often save a length of 0.45 meter), wherein: four telescopic single poles 6 connect into square extension ladder by cross bar 4, it is provided with cross bar 4 on each pole body of four telescopic single poles 6, the junction of each cross bar 4 and four telescopic single poles 6 is provided with fixed cover 5, and four telescopic single poles 6 are respectively provided with an inclined support bar 1；Four telescopic single poles 6 are made by reinforced plastic glass fibre material.
Fixed cover 5 is rubber adapter sleeve, makes cross bar 4 fix with telescopic single pole 6 by tight fit, or, fixed cover 5 screw insulator set, make cross bar 4 fix with telescopic single pole 6 by threaded engagement.
Inclined support bar 1 upper end is connected by anchor ear 3 and four telescopic single poles 6 are movable, it is possible to dismounting, carries out dismounting use according to practical situation, and, inclined support bar 1 lower end is provided with leg, increases the steadiness of whole ladder.
Being provided with middle studdle 2 between inclined support bar 1 and four telescopic single poles 6, middle studdle 2 two ends are connected by anchor ear single pole 6 telescopic with inclined support bar 1 and four is movable respectively, it is possible to dismounting.
It is provided with tool shelf (being not drawn in figure) on the cross bar 4 on top, tool shelf is provided with fixed mechanism, it is possible to place and fix maintenance tool.
During use, determining the stretching, extension height of ladder according to the height of maintenance, maintainer is trampled and is carried out maintenance work on cross bar 4, and maintenance tool is taken from tool shelf or carries with, very convenient.
