Abstract
The utility model discloses a height -adjustable's combination formula motor maintenance ladder, it includes left side arc multistep ladder, the side fixed mounting of left side arc multistep ladder has left connecting block, the side fixed mounting of right side arc multistep ladder has right connecting block, constitute the round pin hub connection between left side connecting block and the right connecting block, there are 4 screw threads support standpipes the bottom of left side arc multistep ladder and right side arc multistep ladder fixed mounting respectively, the screw thread bracing piece constitutes screw drive connection with screw thread support standpipe, the universal wheel is all installed to the bottom of every screw thread bracing piece, be provided with brake brake pedal on the universal wheel. This maintenance ladder has combined the advantage of traditional ladder and maintenance platform, has solved the potential safety hazards problem in traditional ladder, has solved general maintenance platform and has set up the just difficult problem that removes of motor that wastes time and energy.
Description
Technical field
The utility model relates to a kind of Novel ladder for machinery check and repair, particularly relates to a kind of adjustable for height Combined motor maintenance ladder.
Background technology
Large-size machine uses more and more extensive in factory and enterprise, and inspection and maintenance motor has become an inevitable job.When maintenance motor relates to high-rise working, the method adopted at present mainly contains two classes: first by erection ladder, and people stands in the enterprising line operate of ladder; Second by setting up inspection platform, and people stands in the enterprising line operate of inspection platform.
Mainly there is the problem of following two aspects for high-rise working aid during above-mentioned machinery check and repair: the first, motor is cylinder, and existing ladder leans against on motor and becomes point cantact easily to slide with motor on the market, and secure context exists hidden danger; The second, but avoid the defect of ladder though set up inspection platform waste time and energy, and inspection platform is once set up, motor position is relatively fixing, not malleable, causes certain trouble to electric motor shift maintenance.
Utility model content
The purpose of this utility model is to provide a kind of adjustable for height Combined motor maintenance ladder, this maintenance ladder combines the advantage of traditional ladder and inspection platform, solve the hidden danger problem in traditional ladder, solve general inspection platform and set up and waste time and energy and the problem of motor not easily movement.
In order to realize above-mentioned technical characteristic, the technical solution adopted in the utility model is: a kind of adjustable for height Combined motor maintenance ladder, it comprises left side arc multistep ladder, the side of left side arc multistep ladder is installed with left contiguous block, the side of right side arc multistep ladder is installed with right contiguous block, pinned connection is formed between left contiguous block and right contiguous block, the bottom of left side arc multistep ladder and right side arc multistep ladder is installed with 4 threaded support vertical tubes respectively, threaded support bar and threaded support vertical tube form screw-driven and are connected, the bottom of every root threaded support bar is all provided with universal wheel, universal wheel is provided with brake pedal.
Described threaded support bar is provided with quincunx nut and supports vertical tube for locking screw thread.
Described left contiguous block is provided with bearing pin.
Described right contiguous block is processed with dowel hole.
The side of described left side arc multistep ladder and right side arc multistep ladder is all welded with guardrail.
The utility model has following beneficial effect:
In use, brake pedal is arranged on universal wheel, universal wheel is fixed on threaded support bar, the quincunx nut of locking screw thread support bar mates with threaded support bar, threaded support bar is installed in tapped threaded support vertical tube, the left contiguous block being provided with bearing pin is fixed on the arc multistep ladder of left side, and the right contiguous block being provided with dowel hole is fixed on the arc multistep ladder of right side.Constitute single height adjustable arc multistep ladder like this.During two ladder combinations, bearing pin is connected with dowel hole, can be combined into arbitrarily angled between the two, a lot of ladders can be combined like this.
Single ladder can independently use, and possesses height adjusting function, and the cambered design of ladder well can be fitted with motor, single ladder lie against on ground be one independently inspection platform meet use time safety requirements; When two and above ladder combine use time, form relatively large inspection platform and be trapped among wherein by motor, when motor needs displacement, this large-scale inspection platform can off-the-line fast, so just meets the requirement of Fast transforms during inspection platform use.
