Description
Technical field
The invention belongs to ladder technical fields, and in particular to a kind of adjustable double ladder of power equipment.
Background technique
A kind of ascending tool for fit up etc work for side space in the plane is known as double ladder, because of its use
When, the ladder bars of front and back and ground constitute an isosceles triangle, it appears that are known as " people " word, thus its image
" double ladder ".Practical double ladder has fixed double ladder and moving herringbone ladder.Fixed double ladder is that people temporarily build tool；It is living
Dynamic double ladder is that the top of two ladders is connected together with loose-leaf, can be flexible due to it altogether when mobile
Property, therefore be widely used in electrician's operation.But often there is ladder because of ground out-of-flatness when in use in electrician
The larger situation of the gradient of placement, at this moment ladder lower end can generate biggish setback force, as a result be easy for causing ladder along ground
Face slides backward and falls down, and brings danger to the operating personnel on ladder.
Summary of the invention
The purpose of the present invention is to provide a kind of adjustable double ladders of power equipment, to solve to mention in above-mentioned background technique
Out the problem of.
To achieve the above object, the present invention provides the following technical solutions：A kind of adjustable double ladder of power equipment, including
Strut, the strut include upper rack posts and lower fulcrum bar, and the upper rack posts are equipped with location hole, and the upper rack posts and loose-leaf are hinged,
The upper rack posts are equipped with groove, and flexible ladder bars are equipped in the groove, and the lower fulcrum bar is equipped with positioning pin, the lower fulcrum bar
It is connect between lower fulcrum bar by fixed transverse rod, the fixed transverse rod is equipped with pin hole and pin, the lower fulcrum bar and lower branch
Ladder bars are equipped between bar.
Preferably, the strut is equipped with 4.
Preferably, the lower fulcrum bar lower end is fixedly connected with insulation foot pad.
Technical effect and advantage of the invention：The adjustable double ladder of the power equipment, as staff in use, by double ladder
Moving to needs place to be used, is matched required for regulating double ladder by the location hole and positioning pin that are arranged on strut
Highly, by adjusting the pin hole and pin of fixed transverse rod, double ladder is adjusted to required support angle, it is ensured that double ladder
Always in level, it ensure that stability when double ladder uses, avoid staff from dropping because of the shaking of double ladder, cause
Flexible ladder bars are finally erected in the groove of upper rack posts by personal safety accident by its retractility, and staff can use；
The configuration of the present invention is simple, easy to adjust, use is safe, is worthy to be popularized.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is left view of the invention.
In figure：1 strut, 2 upper rack posts, 3 lower fulcrum bars, 4 location holes, 5 loose-leaves, 6 grooves, 7 flexible ladder bars, 8 positioning pins, 9 are consolidated
Determine cross bar, 10 pin holes, 11 pins, 12 ladder bars, 13 insulation foots pad.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of adjustable double ladder of power equipment as shown in Figs. 1-2, including strut 1, the supports
Bar 1 includes upper rack posts 2 and lower fulcrum bar 3, and the upper rack posts 2 are equipped with location hole 4, and the upper rack posts 2 and loose-leaf 5 are hinged, described
Upper rack posts 2 are equipped with groove 6, and flexible ladder bars 7 are equipped in the groove 6, and the lower fulcrum bar 3 is equipped with positioning pin 8, the lower branch
It is connected between bar 3 and lower fulcrum bar 3 by fixed transverse rod 9, the fixed transverse rod 9 is equipped with pin hole 10 and pin 11, under described
Ladder bars 12 are equipped between strut 3 and lower fulcrum bar 3, the strut 1 is equipped with 4, and 3 lower end of lower fulcrum bar is fixedly connected with insulation foot pad
13。
The adjustable double ladder of the power equipment, as staff in use, double ladder, which is moved to, needs place to be used,
Height required for regulating double ladder is matched by the location hole 4 and positioning pin 8 that are arranged on strut 1, it is solid by adjusting
The pin hole 10 and pin 11 for determining cross bar 9 are adjusted double ladder to required support angle, it is ensured that double ladder is in water always
It is flat, it ensure that stability when double ladder uses, avoid staff from dropping because of the shaking of double ladder, cause personal safety thing
Therefore be finally erected at flexible ladder bars 7 in the groove 6 of upper rack posts 2 by its retractility, staff can use；The present invention
Structure is simple, easy to adjust, and use is safe, is worthy to be popularized.
Finally it should be noted that：The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
