Abstract
The utility model relates to a telescopic insulating ladder which comprises an insulating ladder, wherein, the insulating ladder comprises a left side beam, a right side beam and a footboard arranged between the left side beam and the right side beam, the left side beam, the right side beam and the footboard are all made of insulating materials, the insulating ladder further comprises a base ladder and a telescopic ladder, sliding chutes are respectively arranged at the rear ends of the left side beam and the right side beam, a left side beam and a right side beam of the telescopic ladder are respectively installed in the sliding chute, and the telescopic ladder and the base ladder are positioned through a positioning device. Universal connectors are respectively connected at the bottom ends of a left side beam and two right side beams of the base ladder in a fixed manner. Since the two sections of the ladders are arranged in a telescoping manner, the ladder can be adjusted according to the height, meanwhile, the ladder is shortened after retraction when not in use so as to be convenient for transportation and laying; and when in use the universal connectors are arranged, in order that the base ladder is firmly fixed and is safe and stable.
Description
Technical field
The utility model relates to a kind of ladder, relates to a kind of telescopic Insulation ladder that can be used in the livewire work environment specifically.
Background technology
Existing Insulation ladder is made of left and right curb girder and the foot rest that is arranged on therebetween mostly, and the material of left and right curb girder and foot rest is insulation materials, is mainly used in the maintenance of ultra-high-tension power transmission line.Insulation ladder generally is made up of a joint ladder at present, as Chinese utility model patent, application number is 200720088378.7, denomination of invention is " an anti-skidding insulated ladder ", it comprises insulated ladder, universal coupling head, has contact with, insulated ladder is made of left side beam, right side beam and foot rest, and foot rest is fixedlyed connected between left side beam and right side beam and with left side beam, right side beam, and the material of left side beam, right side beam, foot rest is respectively insulation materials; The left side beam of insulated ladder, the leading section of right side beam are fixedlyed connected with the left and right end portions of having contact with by first bolt, the 4th bolt respectively, the left side beam of insulated ladder, the fixedly connected one universal coupling head respectively of the rearward end of right side beam, the good characteristics of this utility model property simple in structure, easy to use, safe, be restricted but be to use highly, can not be in the ultra-high-tension power transmission line of differing heights, and transportation is inconvenient.The Insulation ladder that a kind of more piece combination is also arranged, as Chinese utility model patent, application number is 200720129956.7, denomination of invention is " 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, the two stands upper outside of every joint ladder all is fixed with a connecting ring, this utility model can realize the highly function of adjusting, but complex structure, and base does not have fastening devices, during use, decline easily, unstable, dangerous.
Summary of the invention
The purpose of this utility model just is to overcome the flexible insulating ladder that above-mentioned deficiency provides a kind of simple in structure, safety and stability.
The technical solution of the utility model is:
A kind of flexible insulating ladder, it comprises Insulation ladder, Insulation ladder is made of left side beam, right side beam and the foot rest that is arranged on therebetween, left and right curb girder and foot rest are insulation materials, Insulation ladder is made of base ladder and extension ladder, rear end at left side beam and right side beam is respectively arranged with chute, the left side beam of extension ladder, right side beam are installed in the chute respectively, extension ladder and base ladder are fixed by positioner, and the stretching structure of flexible insulating ladder is as the stretching structure of fire-fighting extension ladder.
Above-mentioned flexible insulating ladder, the fixedly connected one universal coupling head respectively of the bottom of the left side beam of described base ladder, right two curb girders.
Above-mentioned flexible insulating ladder, described positioner are located at the top of the left and right curb girder of base ladder or are located at the bottom of the left and right curb girder of extension ladder.
Above-mentioned flexible insulating ladder, described positioner are alignment pin or locator card.
The utility model is because flexible setting the between the two joint ladders, can be during use according to highly regulating, simultaneously not after the time spent indentation ladder shortened, conveniently transport and put, in use owing to be provided with universal coupling head, the fixation of base ladder, is stablized safety.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that Fig. 1 curb girder section A-A is to sectional drawing.
The specific embodiment
A kind of flexible insulating ladder as depicted in figs. 1 and 2, it comprises Insulation ladder, Insulation ladder is made of left side beam, right side beam and the foot rest 4 that is arranged on therebetween, left and right curb girder and foot rest are insulation materials, Insulation ladder is made of base ladder 7 and extension ladder 5, be provided with left chute 10 in the rear end of base ladder left side beam 2, the rear end of base ladder right side beam 8 is provided with right rail 11, the left side beam 1 of extension ladder is installed in the left chute 10, the right side beam 12 of extension ladder is installed in the right rail 11, and extension ladder and base ladder are fixing by positioner 6.
The stretching structure of flexible insulating ladder is as the stretching structure of fire-fighting extension ladder.
The specifically bottom fixedly connected one universal coupling head 9 of the right side beam 8 of the bottom fixedly connected one universal coupling head 3 of the left side beam 2 of base ladder, base ladder, described positioner is located at the top of base ladder left side beam and right side beam, promptly is equipped with positioner on the top of two curb girders.
Positioner can also be located at the bottom of extension ladder left side beam and right side beam, promptly is equipped with positioner in the bottom of the left and right curb girder of extension ladder.
Described positioner is an alignment pin, can also be locator card, perhaps other structures that can locate.
Operating principle of the present utility model: during use universal coupling head is fixed on the object,, again extension ladder and base ladder is fixed with positioner according to highly opening extension ladder, just can use, not the time spent, untie positioner, in extension ladder indentation base ladder.
