Description
Technical field
The present invention relates to power construction maintenance of equipment fields, change three particularly with regard to a kind of framework vertical support structure
The power equipment maintaining ladder of angle center of gravity.
Background technique
Current household power maintenance ladder is used in interior more, and smooth metope and ground using effect be most indoors
It is good, but it is frequently encountered the problem of ground out-of-flatness can not place in staircase use, it needs at present in staircase to smallpox
Power equipment maintaining personnel are to open ladder as water using first framework one when the lamps and lanterns or route of plate ceiling are adjusted maintenance
Plane, flushes it with stair face with manual support, then places the maintenance ladder of another Zhang San's corner structure on this basis to top
The way that the electric power facility of canopy repairs, it is done so that bottom whether placed as the electric power ladder of horizontal plane it is smooth especially heavy
It wants, places injustice and easily cause another of top power equipment maintaining ladder gravity center instability and turn on one's side and topple over, not only need two people or more
Cooperation can just repair, and due to maintenance personal's body limited strength of bottom support, can not long-time held stationary station
It is vertical to provide a stable support to ladder, the personal safety of maintenance person can not also be effectively ensured, so being badly in need of researching and developing a kind of special
Power equipment maintaining ladder for being used at the injustice of the ground such as staircase.
Summary of the invention
In view of the deficiencies of the prior art, the present invention is to realize by the following technical solutions: a kind of framework vertical support
Structure changes the power equipment maintaining ladder of triangle center of gravity, and structure includes: vertical linking pneumatic mechanism, maintenance ladder main body, described vertical
Linking pneumatic mechanism is connected with maintenance ladder main body using chimeric mode, and the vertical linking pneumatic mechanism is by upper anti-skidding top plate, gas
Press adjusting rod, adjust lock device, under anti-skidding fagging, adjustable limiting deck, indent card slot composition, the upper anti-skidding top plate is by can
Limit deck is adjusted to connect pneumatic nozzle link, the pneumatic nozzle link, which is equipped with, adjusts lock device, and anti-skidding fagging is located at gas under described
Adjusting rod bottom is pressed, the pneumatic nozzle link is equipped with indent card slot, and upper anti-skidding top board surface is made of silica gel, mainly right
