Abstract
The invention relates to a movable insulating ladder special for a transformer substation. The movable insulating ladder mainly comprises a ladder body, wherein the ladder body is composed of cross bars and vertical bars by connecting pieces, one side of the front surface of the ladder body is provided with at least three steps, four landing ladder feet of the ladder body are provided with insulating rubber mats, a low cross bar is arranged at the lower parts of the left vertical bar and the right vertical bar on the back surface of the ladder body, two rubber rollers horizontally stretching outwards and used for enabling the ladder body to move freely are arranged at two sides of the lower cross bar respectively, an N-shaped grab rail higher than the highest step surface is arranged at the upper end of the back surface of the ladder body, three steps are arranged on the front surface of the ladder body, the step surface is formed by an anti-skid insulating footboard fixed on a ladder frame surface formed by the cross bars and the vertical bars through the connecting pieces, the grab rail is fixed at the upper parts of the left vertical bar and the right vertical bar on the back surface of the ladder body by one upper cross bar, and an anti-skid rubber sleeve is sheathed on the grab rail. The movable insulating ladder has the characteristics of simple structure, and convenience and rapidness in using, the working efficiency is improved, and the labor cost is reduced.
Description
Technical field
What the present invention relates to is a kind of transformer station special mobile insulating ladder, belongs to the Work tool technical field of power equipment.
Background technology
While carrying out work in electric substation, often need to carry out ascend operation, in existing situation, we carry out truck work with small stool, the solid objects such as chest conventionally, or carry the special-purpose ascending tools such as double ladder.But use the objects such as small stool or chest to carry out truck work, be conventionally not steady on one's legs; We,, when carrying out truck work, need the different height of ascending a height, and the objects such as these small stools or chest are too high or too low in addition, and height cannot regulate, and causes the inconvenience of work; Although the special-purpose ascending tool such as double ladder can address the above problem, this class ladder is often too little with sole contact area, stands for a long time and can cause sole pain, and truck work is caused to potential safety hazard.In addition, no matter be to use the objects such as small stool, chest, or special-purpose ascending tool, all there is a problem can not be ignored, be exactly we when carrying out truck work, often need to carry out ascend operation in different job sites, this just needs often carrying ascending tool, comprise the objects such as small stool and chest, and these objects and ladder generally heavier, between different location, carry, to staff, cause very large inconvenience, and can increase human cost, reduce service efficiency.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and provide a kind of simple in structure, convenient to use, increase work efficiency, reduce transformer station's special mobile insulating ladder of human cost.
The object of the invention is to realize by following technical solution, it mainly comprises that one is that consist of connector crosspiece and vertical file, a side has the terraced body of three stairstepping steps at least before it, four of described terraced body land foot of ladder and are provided with insulation rubber cushion, two vertical file bottoms, left and right, the back side at terraced body are provided with a bottom rail, and the level that is separately installed with on the both sides of described bottom rail two rubber rolls overhanging, that move freely for terraced body.
The upper end at the described terraced body back side be provided with a N-type, exceed the bar of high step surface; Before described terraced body, be provided with three stairstepping steps, step surface by anti-skidding insulation footboard be fixed on by crosspiece and vertical file, by connector, formed ladder face on form.
Described bar is fixed on the top of left and right, the terraced body back side two vertical files by a top rail, be equipped with anti-slip rubber cover on bar.
The present invention has simple in structure, convenient to use, increases work efficiency, and reduces the features such as human cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the side-looking structural representation of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is shown in detailed introduction: Fig. 1,2, the mobile insulating ladder that transformer station of the present invention uses, it mainly comprises that one is that form by connector 3 by crosspiece 1 and vertical file 2, a side has the terraced body 5 of three stairstepping steps 4 at least before it, people can select the work of standing of a certain step by required height of ascending a height, the highest can go to the highest, above three stage rank; Four of described terraced body 5 land foot of ladder and are provided with insulation rubber cushion 6, and this ladder body is tetragonal body and lands, and steadiness is good, and foot of ladder contacts with ground by insulation rubber cushion, has guaranteed user's trouble free service; Two vertical file 2 bottoms, left and right, the back side at terraced body 5 are provided with a bottom rail 7, and the level that is separately installed with on the both sides of described bottom rail 7 two rubber rolls 8 overhanging, that move freely for terraced body; If need the ramp period of the day from 11 p.m. to 1 a.m, as long as by the terraced body certain angle of overturning backward, make roller 8 kiss the earths, four foot of ladders upwarp the operating position that can facilitate ramp body.
Shown in figure, the upper end at described terraced body 5 back sides be provided with a N-type, exceed the bar 9 of high step surface, this bar is convenient to user, and by terraced body, overturning is angled backward, is convenient to user ramp body; Described terraced body 5 is provided with three stairstepping steps 4 above, step surface by anti-skidding insulation footboard 10 be fixed on by crosspiece 1 and vertical file 2, by connector 3, formed ladder face on form.
Described bar 9 is fixed on the top of terraced body 5 left and right, the back side two vertical files 2 by a top rail 11, be equipped with anti-slip rubber cover 12 on bar 9.
Crosspiece 1 of the present invention and vertical file 2 are made by square hollow epoxy glass-reinforced plastic material; Connector 3, bottom rail 7 are made by galvanized iron sheet, all by rivet, are fixed on insulating ladder; Bar 9 is galvanized iron conduit, and pedal 10 is glass fiber reinforced plastic antiskid pedal.
