Abstract
The invention discloses a safe insulating herringbone ladder. The safe insulating herringbone ladder is characterized in that nut holes parallel to supporting rods are formed in the upper side of a ladder body of a fixed ladder; fixed grooves are hinged with the bottom ends of the ladder body of the fixed ladder through pin shafts, one ends, close to the pin shafts, of the fixed grooves are smooth, and jagged grooves are formed in the other ends of the fixed grooves; supporting fixing plates are arranged on the outer sides of the fixed grooves; a layer of insulating rubber anti-slide pad is fixedly arranged on the lower sides of one fixed groove and one supporting fixing plate, respectively; fixed nuts matched with the nut holes in the ladder body of the fixed ladder are arranged at the tail ends of the jagged grooves; fixed rods matched with the jagged grooves are arranged at the bottom end of a ladder body of a movable ladder. According to the safe insulating herringbone ladder, a contact area between the bottom ends of the ladder and the ground is increased, so that the herringbone ladder is stable and safe; the fixed grooves can be folded and fixed between the fixed ladder and the movable ladder in the carrying process of the herringbone ladder, so that the herringbone ladder is convenient to carry; furthermore, an opening angle of the herringbone ladder can be adjusted.
Description
Technical field
The invention belongs to electric power overhaul utensil technical field, be specifically related to a kind of safe insulation double ladder.
Background technology
When power equipment maintaining ascend operation, maintainer can often use double ladder, angle when China's grid power safety code is used insulating ladder and highly have corresponding requirement, but in actual mechanical process, maintainer is generally difficult to control insulating ladder to reach corresponding safety requirements.Existing double ladder only has four pin to support ground conventionally, and contact area is less, uses stablely not, has larger potential safety hazard.For conventional double ladder, conventionally use rope to realize double ladder and separate certain angle, separately the size of angle is unadjustable.
Summary of the invention
The object of the present invention is to provide a kind of safe insulation double ladder, effectively solved the problem of above-mentioned existence.
Technical scheme of the present invention is: a kind of safe insulation double ladder, comprise ladder main body, this ladder main body mainly consists of movable ladder and fixed ladder, wherein the top of movable ladder and fixed ladder is hinged by bearing pin, movable ladder and fixed ladder are formed by connecting by terraced body and support bar, it is characterized in that: the ladder of described fixed ladder with it side is provided with the nut bore parallel with support bar, terraced body bottom at fixed ladder is hinged with fixed groove by bearing pin, fixed groove is smooth near one end of bearing pin, the other end has serrated slot, in the outside of fixed groove, be provided with support fixed head, the downside of described fixed groove and support fixed head is fixed with respectively one deck electro-insulating rubber slipmat, end in serrated slot is provided with the hold-down nut matching with fixed ladder ladder nut bore with it, the terraced body bottom of described movable ladder is provided with the fixed bar matching with serrated slot.
The present invention has increased the contact area on ladder bottom and ground, makes double ladder stability and safety more, and double ladder fixed groove in handling process can be turned up and be fixed between fixed ladder and movable ladder, be convenient for carrying, and the opening angle of ladder can regulate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Drawing explanation: 1, fixed groove, 2, ladder main body, 3, bearing pin, 4, serrated slot, 5, fixed bar, 6, support fixed head, 7, hold-down nut, 8, nut bore, 9, electro-insulating rubber slipmat.
The specific embodiment
Describe by reference to the accompanying drawings embodiment in detail.A kind of safe insulation double ladder, comprise ladder main body 2, this ladder main body 2 mainly consists of movable ladder and fixed ladder, wherein the top of movable ladder and fixed ladder is hinged by bearing pin, movable ladder and fixed ladder are formed by connecting by terraced body and support bar, the ladder of described fixed ladder with it side is provided with the nut bore parallel with support bar 8, terraced body bottom at fixed ladder is hinged with fixed groove 1 by bearing pin 3, fixed groove 1 is smooth near one end of bearing pin 3, the other end has serrated slot 4, in the outside of fixed groove 1, be provided with and support fixed head 6, the downside of described fixed groove 1 and support fixed head 6 is fixed with respectively one deck electro-insulating rubber slipmat 9, end in serrated slot 4 is provided with the hold-down nut 7 matching with fixed ladder ladder nut bore 8 with it, the terraced body bottom of described movable ladder is provided with the fixed bar 5 matching with serrated slot 4.
