Abstract
The utility model discloses a collapsible second order ladder of ascending a height belongs to the equipment of ascending a height field. Its technical scheme's main points are: including first ladder, second ladder, the second ladder is connected and can be taken in in the inside of first ladder through slide rail and first ladder, first ladder side is equipped with the spout, is connected with one on the spout and can follows the ladder that the spout reciprocated, becomes articulated state when the top of spout is moved to the bottom of ladder between ladder and the spout. The utility model discloses in the work of the operation and maintenance management of mainly used transformer substation, its have save space, convenient to use's advantage.
Description
Technical field
This utility model belongs to a kind of step ladder, specifically, particularly relates to a kind of collapsible second order step ladder.
Background technology
At present, in the operation management of transformer station works, need to install transformer equipment, but also need to put up, more exchange device
First and second indicates, power transformer product and the setting height(from bottom) of mark and difficulty are improving constantly, the installation height of different product
Position is different with angle, and traditional insulating ladder and aerial device the most do not adapt to the needs of transformer station's maintenance work, traditional
There is following defect in insulating ladder and aerial device: (1) does not adapt to differing heights requirements of one's work；(2) folding can not be received, account for
Big with space；(3) heavy, it has not been convenient to mobile.
Utility model content
This utility model purpose is to provide a kind of folding storage and collapsible second order step ladder easy to use, to overcome existing skill
The drawbacks described above of art.
This utility model realizes by the following technical solutions: a kind of collapsible second order step ladder, including the first ladder, second
Ladder, described second ladder is connected by slide rail and the first ladder and can be accommodated in the inside of the first ladder, described first ladder side
While be provided with chute, chute connect and has a ladder that can move up and down along chute, when basal sliding the going up most to chute of ladder
Hinged state is become between ladder and chute during end.
Described ladder is scalable ladder.
It is respectively equipped with pulley bottom described first ladder, the second ladder.
Described pulley is provided with brake gear.
Compared with prior art, the beneficial effects of the utility model are: (1) this utility model comprises ascending a height of two differing heights
Ladder, and one of them is ascended a height, ladder can be accommodated in the inside of another ladder of ascending a height, and saves substantial amounts of space, collection and
Use very convenient；(2) also slidably connect a Collapsible ladder on this utility model, climbing when ladder is holded up, can be increased
Height, be placed in side of the present utility model when putting down, be not take up additional space.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1, the first ladder；2, the second ladder；3, ladder；4, chute；5, pulley；6, slide rail.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of collapsible second order step ladder, including first ladder the 1, second ladder 2, described second ladder 2 leads to
Cross the inside that slide rail 6 is connected with the first ladder 1 and can be accommodated in the first ladder 1, during use, the second ladder 2 is skidded off, permissible
Meeting the needs of differing heights, the second ladder 2 is not accommodated in the inside of the first ladder 1 by the used time, is not take up exceptional space.
Described first ladder 1 side is provided with chute 4, and chute 4 connects a ladder 3 that can move up and down along chute 4, when
Become hinged state between bottom and chute 4 top of ladder 3 when the bottom of ladder 3 moves to the top of chute 4, use
Time ladder 3 is extracted out in chute 4, become hinged state, by ladder 3 during use bottom ladder 3 and between chute 4 top
Lean against in rest, the climbing height of the first ladder 1, ladder 3 preferably scalable ladder can be increased, can increase further
The height climbed.
Being respectively equipped with, bottom described first ladder the 1, second ladder 2, the pulley 5 being easy to movement, pulley 5 is provided with brake gear,
Pulley 5 is locked in advance to prevent it from moving during climbing.
