Abstract
The invention discloses an insulated lift maintaining platform ladder. A herringbone ladder which is supported on the ground comprises two support legs; the two support legs are connected by two limiting tension plates; a lift ladder is vertically arranged on the top of the herringbone ladder by a lift pulley component; a working platform and a fence are arranged on the upper section of the lift ladder; a roller support of the lift pulley component is fixed on the top of the herringbone ladder; at least two groups of fixed rollers are arranged on the roller support; and two struts of the lift ladder are clamped between the front and rear groups of the rollers and are driven by the rollers. The ladder can enter a place where a live working vehicle cannot enter and can be self-fixed by adopting a design of the herringbone ladder, so the ladder has high geography adaptability, and is more stable and safer. An outer support leg of the herringbone ladder is provided with an adjustable component, and an angle can be adjusted left and right by the adjustable component; and the lift maintaining platform can stretch up and down, so a maintainer can always perform maintaining at the best position. The ladder has the advantages of convenient and quick assembling and disassembling, and greatly increased work efficiency of the maintainer.
Description
Technical field
But the present invention relates to a kind of live line tool, specifically is a kind of insulated lift maintaining platform ladder.
Background technology
The place of charging construction operation such as transformer etc., general on the electric pole or support of distance ground certain distance, personnel's ascend operation needs repairing.Because the scene mostly is open air, flower every band or mud ground place, ground is uneven, and flowers and shrubs is arranged again, and the general repair apparatus of ascending a height can't satisfy construction requirement.
The existing repair apparatus of ascending a height is based on bucket arm vehicle, but bucket arm vehicle is bulky, heaviness, and when landform was complicated, bucket arm vehicle often can't be stopped and put in place, even can't enter the scene at all, has brought endless trouble to the constructor.And also there are problems such as heaviness, installation can't put in place in other some instruments of ascending a height, and because insulation effect is poor, also have potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention provides a kind of livewire work demand that satisfies, and not influenced by orographic condition, and installing and locating accurately is convenient to the insulated lift maintaining platform ladder regulated again.
Insulated lift maintaining platform ladder of the present invention, it is characterized in that comprising double ladder, spacing arm-tie, lifting pulley assembly, lift, working platform, the described double ladder that is supported on ground comprises two legs, two spacing arm-ties are connected two legs of double ladder by both sides, lift is vertically mounted on the double ladder top by the lifting pulley assembly, and working platform and fence are installed in the lift epimere.
Described lifting pulley assembly comprises rolling wheel support, fixed idler whell, rope sheave and lockable mechanism, and described rolling wheel support is fixed on the double ladder top; At least two group fixed idler whells vertically are arranged on the rolling wheel support, and two pair rollers before and after every group of fixed idler whell divides also can be driven by roller between two teams' roller before and after two pillars of lift are clipped in and realize that lift moves up and down; Rope sheave is fixed therein on the wheel shaft of a pair roller; Lockable mechanism is installed on the lift.Wherein lockable mechanism is the rotatable braking vane that is arranged on the lift.
In order to adapt to uneven ground, on double ladder one side leg, be provided with the adjustable component of regulating length.Be provided with the aluminium alloys base in double ladder two legs bottom and then can improve stability.
One end of spacing arm-tie and double ladder one leg are rotatably connected, and the other end is provided with draw-in groove, are provided with the buckle that cooperates with draw-in groove at another leg correspondence position of double ladder.During without ladder, can unclamp the buckle draw-in groove,, be convenient to transportation packing up of double ladder.
In order to make rolling wheel support keep vertical and fixing, both sides at the double ladder epimere are respectively equipped with fixed link plate, fixed link plate one end is rotatable to be arranged on double ladder one leg, the other end is provided with two draw-in grooves, is provided with the buckle that cooperates with draw-in groove at the correspondence position of rolling wheel support and another leg of double ladder.
Livewire work lift maintaining platform of the present invention has following beneficial effect.
1, the unapproachable place of livewire work car, livewire work lift maintaining platform can replace as ascending a height apparatus.
2, the design of double ladder is adopted in livewire work lift maintaining platform below, can fix voluntarily, and the compliance of landform is good, and more firm safety.
3, the outer leg of double ladder is provided with adjustable component, can the left and right adjusting angle by this assembly, and also lift maintaining platform can stretch up and down, and the maintainer can be overhauled in the optimum position all the time.
4, the installation of livewire work lift maintaining platform, dismounting are convenient rapidly, have improved maintainer's operating efficiency greatly.
