Abstract
The utility model relates to an adjustable maintenance ladder, including the main support, the truss structure that the main support formed for shaped steel welding, the main support side sets up step plate, and the top is provided with platform and railing, the main support bottom is provided with gyro wheel and stabilizer blade, the stabilizer blade includes the base, and base upper portion sets up the lead screw, the main support be provided with with lead screw complex screw, lead screw length are 0.5~1 meter, and lead screw upper end is provided with the handle, and the handle is arranged in the truss structure clearance of main support, vertical direction is followed to the lead screw axial, and lead screw length is greater than the interval of gyro wheel lower surface bottom the main support. Above -mentioned adjustable maintenance ladder, the main support bottom has promotion that the gyro wheel can be convenient to the place that needs, can rotate the handle afterwards, makes the lead screw stretch out downwards, makes the base form with the ground contact and supports, as required can also be through rotatory handle accommodate the lead screw's extending distance, and then change maintenance ladder's height.
Description
Technical field
This utility model is related to the ladder of a kind of maintenance aircraft or other equipment, and particularly one kind has roller and permissible
Adjust the maintenance ladder of ladder height.
Background technology
When overhauling aircraft or other tall and big equipment, workman needs to stand in operation in ladder or plateau, and existing general
Logical ladder or the plateau built generally all adopt the higher material of intensity, such as shaped steel etc., and this leads to ladder, platform weight all
Ratio is larger, and workers carry is relatively difficult.
Utility model content
Technical problem to be solved in the utility model is: provides a kind of scalable maintenance ladder, has stable during use
Support, need when carrying, can easily be pushed to the place of needs.
This utility model solves its technical problem and be the technical scheme is that
Scalable maintenance ladder, the truss structure being formed for shaped steel welding including main support, described main support, main support side
Setting stepped plate, top is provided with platform, and the surrounding outside platform is located at stepped plate place side is provided with railing；Main support bottom
It is provided with roller and leg, described leg includes base, base top arranges screw mandrel, main support is provided with and the cooperation of described screw mandrel
Screw, screw mandrel length is 0.5～1 meter, and screw mandrel upper end is provided with handle, and handle is located at the truss structure gap of main support
In, axially vertically, screw mandrel length is more than the spacing of described roller lower surface and main support bottom to described screw mandrel.
Further, main support bottom is provided with four described rollers and four described legs.
The beneficial effects of the utility model are: above-mentioned scalable maintenance ladder, main support bottom has roller can be convenient
It is pushed to the place of needs, subsequently screw mandrel can be made to extend downwardly from rotating handles, make base contact formation with ground and support, root
The outreach of screw mandrel can also be adjusted according to needs by rotating handles, and then change the height of maintenance ladder.
Brief description
Fig. 1 is scalable maintenance ladder structural representation of the present utility model；
In figure reference is: main support 1, railing 11, roller 12, leg 13, base 131, screw mandrel 132, handle 133,
Stepped plate 2.
Specific embodiment
With reference to the accompanying drawings and examples this utility model is further illustrated:
Scalable maintenance ladder, the truss structure being formed for shaped steel welding including main support 1, described main support 1, main support 1
Side arranges stepped plate 2, and top is provided with platform, and the surrounding outside platform is located at stepped plate 2 place side is provided with railing 11；Main
Support 1 bottom is provided with roller 12 and leg 13, and described leg 13 includes base 131, and base 131 top arranges screw mandrel 132, main
Support 1 is provided with the screw with the cooperation of described screw mandrel 132, and screw mandrel 132 length is 0.5～1 meter, and screw mandrel 132 upper end is provided with handle
Handss 133, and handle 133 is located in the truss structure gap of main support 1, described screw mandrel 132 axially vertically, screw mandrel 132
Length is more than the spacing of described roller 12 lower surface and main support 1 bottom.
As shown in figure 1, this scalable maintenance ladder, main support 1 is truss structure, and its side arranges stepped plate 2, for workman
Ascend a height operation along step, main support 1 top setting platform is easy to personnel and is stood, around platform in addition to stepped plate 2 place side all
Setting railing 11, prevents operator from falling.
Main support 1 bottom is provided with roller 12 makes whole maintenance ladder can easily be pushed to maintenance position.Leg 13 wraps
Include base 131 and screw mandrel 132, main support 1 is had screw and coordinated with described screw mandrel 132, rotary screw rod 132, you can make base 131
Stretch out or retract.Screw mandrel 132 length is 0.5～1 meter, and its upper end arranges handle 133, and operator are i.e. operable without bending over.
As shown in figure 1, after maintenance ladder is pushed to the position needing maintenance, rotating handles 133, using leading screw 132 and silk
Female cooperation makes base 131 stretch out, and until base 131 is contacted with ground, continues rotating handles 133, whole main support 1 is supported
Rise, roller 12 departs from ground, now form stable support, workman may stand in operation in maintenance ladder, further, it is also possible to by rotation
Handle handss 133 change the height of main support 1 within the specific limits.
Roller 12 and leg 13 quantity select as needed, can be preferably that main support 1 bottom is provided with described in four
Roller 12 and four described legs 13.
