Abstract
The invention belongs to working stand technology, relate to a kind of multipurpose working stand that can realize double ladder and yi shaped ladder conversion.The working platform (3) that described multipurpose working stand comprises front ladder (1), supports ladder (2) and be arranged on therebetween, wherein, front ladder (1) and support ladder (2) by the folding conversion realizing double ladder and yi shaped ladder of working platform (3).Ride against block (4) upper surface during double ladder bottom working platform, there is alignment pin (5) working platform (3) side, and during double ladder, alignment pin is stuck in the arc chute of the frame block (4) on supporting ladder, and arcuate directions is consistent with working platform overturning track.Multipurpose working stand structure of the present invention is simple, easy to operate, applicability strong, by folding, stretching, can meet multiple occasion maintenance work needs, effectively reduces random work ladder kind and quantity.
Description
Technical field
The invention belongs to working stand technology, relate to a kind of multipurpose working stand that can realize double ladder and yi shaped ladder conversion.
Background technology
First aircraft needs to be equipped with multiple ladder maintenance use, as the working stand in large aircraft cargo hold needs double ladder, and the working stand that large aircraft cargo hold top is safeguarded, the working stand of vertical fin passage, and need yi shaped ladder when aircraft exterior is safeguarded.These working stands stop on other airport will often use when falling to needing to safeguard, need to carry at random, take aircraft space, add weight of equipment to aircraft, and to how to make troubles to transition transport, management.
Summary of the invention
Technical problem to be solved by this invention is: provide that a kind of result is simple, easy to operate, applicability is strong, can meet the multipurpose working stand of multiple occasion maintenance work needs.
Technical scheme of the present invention is: a kind of multipurpose working stand, it working platform 3 comprising front ladder 1, support ladder 2 and be arranged on therebetween, wherein, front ladder 1 and support ladder 2 by rotating, the upset of fixing and working platform 3, be hooked the conversion realizing double ladder and yi shaped ladder.
Ride against block 4 upper surface during double ladder bottom working platform, there is alignment pin 5 working platform 3 side, and alignment pin is stuck in the arc-shaped slot of the block 4 on supporting ladder, and arcuate directions is consistent with working platform overturning track.
There is the handrail 6 that can pull out, take in the pillar of described front ladder side, fix by guide pin bushing 7 after handrail pull-out.
There is telescopic pole 8 in supporting ladder post setting, strut has some connecting holes, stretch out different length pin 9 as required and be connected and fixed in guide pillar 12.
Beneficial effect of the present invention: the fixing alignment pin by working platform side during multipurpose working stand double ladder of the present invention is stuck in the draw-in groove of supporting ladder block, rides against block top bottom working platform, achieve dual fail-safe, therefore ladder has not been required to be and has prevented front ladder be separated with support ladder and arrange insurance pull bar.In addition, adopt hidden telescopic handrail, extract out fixing as required, the component that whole ladder profile does not succinctly expose, and regulate ladder length by folding and telescopic pole, meet the needs that aircraft difference safeguards occasion, there is larger actual application value.

Wherein, before 1-, ladder 2-supports a ladder 3-working platform 4-block 5-alignment pin 6-handrail 7-guide pin bushing 8-telescopic pole 9-pin 10-activity block 11-pedal 12-guide pillar.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
See Fig. 1, technical scheme of the present invention is: a kind of working stand, and a kind of multipurpose aircraft cargo hold working stand, makes primarily of aluminum alloy materials, comprises front ladder 1, supports ladder 2, working platform 3; There are two kinds of using states, double ladder, yi shaped ladder, collapsible placement of finishing using.
Have pedal between front ladder pillar, have telescopic handrail 6 in a lateral brace, handrail end has in the annular groove of bayonet lock on guide pin bushing 7 and rotates and fix.Used time handrail can not be received in pillar, extraction, half-twist during use.General double ladder does not have handrail, working platform is liftoff higher time personnel do not have handrail protect have the danger fallen.Handrail is hidden in when needing in pillar and extracts out, guarantees personal security;
Support top between ladder 2 pillar and have pedal, bottom is telescopic pole 8, and first half pedal can make ladder reach higher operation height in yi shaped ladder state, and telescopic pole can realize the use of the slope ground of different angles.Every root telescopic pole is connected and fixed by two pins 9 and the guide pillar 12 in pillar.Arbitrarily fixing of telescopic pole, solves ground use and need be hooked aircraft arrival differing heights problem.
A movable block 10 is equipped with in telescopic pole bottom, and rubber pad is arranged at bottom.A movable block inside is ball head structure, realizes 360 ° of rotations, can prop up block, make working platform maintenance level in the wall face supporting activity of any slope ground and injustice.
During double ladder, the alignment pin 5 of working platform 3 side is stuck in the arc-shaped slot of supporting ladder block 4, rides against block 4 top bottom working platform, achieve dual fail-safe, eliminate to prevent front ladder and support ladder easily separated and the insurance institutions such as connecting rod are set at this, making ladder outside there is no excessive zero parts.
Structure of the present invention is simple, easy and simple to handle: to be taken in by handrail in pillar, extracts out fixing as required, solves general herringbone, the dual-purpose ladder of a word does not have handrail, personnel step down in security hidden trouble on working platform; Telescopic pole meets the maintenance needs at goods bridge top after large transport airplane.The fixing alignment pin by working platform side of double ladder is stuck in the round nest of supporting ladder block, rides against block top bottom working platform,
This working stand one ladder is multiplex, carries at random, when facility is few, solves after large transport airplane lands temporarily in the wild, inside and outside the maintenances needs of cargo hold and different ladder kind equipment problem.Achieve a ladder multiplex, achieve the requirement of support equipment synthesization.
Working platform terrain clearance can reach 3 meters, and yi shaped ladder height can reach 5 meters, and meet in cargo hold and use requirement for height, it is stable that handrail ensures that personnel stand; The rubber pad of ladder base adds the stability of ladder.Connect simple, firm when using as yi shaped ladder, the rubber pad at backing plate place can not damage and be hooked location external structure.This working stand solves the working stand that aircraft performs temporary duty, other airport of landing is not applicable to and uses problem, to the especially acclive rear goods bridge place of the maintenance of the pipeline such as electric system, air-conditioning system and equipment in aircraft hold, or for providing very big convenience close to vertical fin maintenance channel with to when high-order bit is safeguarded in motor or fuselage.
