Description
Technical field
The present invention relates to a kind of high-lift operation car platform leveling devices with anti-platform tilt functions, belong to high-altitude
Operation Van's technical field.
Background technology
High-altitude operation vehicle is the equipment to work to high-altitude designated position for transporting personnel, tool and material.Its work
Make platform in high-lift operation car, needs to remain in horizontality, to ensure platform operations personnel steadily safety
Ground carries out working at height, it is therefore desirable to working platform leveling device be arranged, its object is to adjust platform when the arm support elevation angle changes
With the angle of arm support, workbench is made to be in level always.Existing collapsible high-altitude operation vehicle mostly uses parallelogram company
Two kinds of forms of bar leveling or chain sprocket leveling.Two kinds of forms are by pull rod or chain is kept and workbench（Contain
Load）The balance of gravity torque makes workbench be in level.Two kinds of forms have simple in structure, good balance effect excellent
Point, but during working at height, can only ensure that working bucket is not tumbled to gravity torque direction, but then lack guarantor in the reverse direction
Shield, when elliptical gear or job platform are by moment loading with gravity torque opposite direction, the oriented gravity torque of job platform
The possibility that opposite direction is tumbled causes personnel and material to be poured out out of workbench, therefore there are security risks.
Chinese document CN201120571760X discloses a kind of high-lift operation car bucket leveling dress with anti-overturn mechanism
It sets, anti-tipping machine is formed for the levelling device and multigroup parallelogram linkage of multigroup parallelogram linkage composition
Structure.The mechanical work principle is correct, but complicated, and installation and adjustment are very inconvenient, needs that each length of connecting rod is adjusted,
The mechanism itself is a kind of positioning device excessively, and error in length can make mechanism generate internal force and damage, and then lead to failure mechanisms
It may.
Invention content
The technical problem to be solved by the present invention is to overcome defect of the existing technology, provide a kind of simple in structure, peace
Fill easy to adjust, leveling continuous and stable, the high-lift operation car platform leveling device with anti-platform tilting mechanism.
To solve the above problems, the technical scheme is that, a kind of high-altitude operation vehicle with anti-platform tilt functions
The working arm of working platform leveling device, high-altitude operation vehicle is followed successively by arm I, arm II, arm III ... until arm X from top to bottom；Work

The relationship of connecing is analogized, and nethermost arm X axises X+1 is hinged with turntable, which is characterized in that at the articulated shaft of each two arm, respectively
Equipped with positive leveling wheel I, positive leveling wheel II ... until positive leveling wheel X+1；At the articulated shaft of each two arm, also set respectively
There are reversed leveling wheel I, reversed leveling wheel II ... until reversed leveling wheel X+1；Positive drag-line is respectively fixed on workbench
The upper end of upper end and reversed drag-line；The forward direction drag-line pass sequentially through positive I outer rim of leveling wheel, positive II outer rim ... of leveling wheel until
Positive leveling wheel X+1 outer rims, the lower end of the forward direction drag-line are connected on the turntable；The reversed drag-line passes sequentially through reversed leveling
I inner edge, reversed II inner edge ... of leveling wheel are taken turns until the reversed inner edges leveling wheel X+1, the lower end of the reversed drag-line are connected to described turn
On platform.
The present invention has following prioritization scheme：
Transition wheel can be respectively arranged with by often saving on working arm, respectively the straight transition wheel X of transition wheel I, transition wheel II ...；With
To adjust trend of the positive drag-line between two positive leveling wheels；Or to adjust reversed drag-line two reversed leveling wheels it
Between trend.
" lower end of positive drag-line is connected on the turntable " and " lower end of reversed drag-line is connected on the turntable "
Connection type is：Regulating device I and regulating device II are provided on the turntable；The lower end of the forward direction drag-line is connected to the tune
On regulating device I；The lower end of the reversed drag-line is connected in the regulating device II.
The regulating device I is by the rotatable nut on turntable, and the screw rod that is fixedly connected with positive drag-line lower end
Composition；The regulating device II is by the rotatable nut on turntable, and the screw rod group that is fixedly connected with reversed drag-line lower end
At.
The diameter of each positive leveling wheel is equal, and the diameter of each reversed leveling wheel is equal.
The forward direction drag-line, reversed drag-line, can be freely curved in two dimensional surface using flexible materials such as steel wire rope or chains
It is bent.
In other words, the present invention proposes a kind of using positive drag-line, reversed drag-line, positive leveling wheel group, reversed leveling wheel
The high-lift operation car platform leveling device with anti-platform tilt functions that group, transition wheel group, regulating device are formed, with
For the high-altitude operation vehicle of 3 sections of working arms：It is provided with positive drag-line, reversed drag-line, positive leveling wheel I, positive leveling wheel II, just
To leveling wheel III, positive leveling wheel IV, reversed leveling wheel I, reversed leveling wheel II, reversed leveling wheel III, reversed leveling wheel IV, work
Make platform, arm I, arm II, arm III, turntable, axis I, axis II, axis III, axis IV, transition wheel I, transition wheel II, transition wheel III, transition wheel
IV, transition wheel V, transition wheel VI, regulating device I, regulating device II；Workbench, positive leveling wheel I, reversed leveling wheel I, arm
I is hinged by axis I, and arm I, positive leveling wheel II, reversed leveling wheel II, arm II are hinged by axis II, arm II, positive leveling wheel
III, reversed leveling wheel III, arm III are hinged by axis III, and arm III, positive leveling wheel IV, reversed leveling wheel IV, turntable pass through axis IV
It is hinged；Transition wheel I is hinged with arm I, and transition wheel II, transition wheel III and arm II are hinged, and transition wheel IV, transition wheel V and arm III are cut with scissors
It connects, transition wheel VI is hinged with turntable；Positive drag-line one end is fixedly connected with workbench, passes through positive I outer rim of leveling wheel, forward direction
II outer rim of leveling wheel, positive III outer rim of leveling wheel, positive IV outer rim of leveling wheel, the other end is connect with turntable passes through regulating device I
Connection；Reversed drag-line one end is fixedly connected with workbench, passes through reversed I inner edge of leveling wheel, reversed II inner edge of leveling wheel, reversely
III inner edge of leveling wheel, reversed IV inner edge of leveling wheel, the other end are connect with turntable by regulating device II.
Forward direction leveling wheel I of the present invention, positive leveling wheel II, positive leveling wheel III, positive IV diameter phase of leveling wheel
Deng a diameter of 2R；Reversed leveling wheel I, reversed leveling wheel II, reversed leveling wheel III, reversed IV diameter of leveling wheel are equal, a diameter of
2r；R can be equal to r.
Transition wheel of the present invention, it is therefore intended that adjust the trend and arrangement of drag-line, ensure drag-line in luffing range of cantilever support mistake
The wheel of envelope leveling always is without departing from for convenience of other component mounting arrangements, transition wheel quantity can increase and decrease, position and half in journey
Diameter can change.Transition wheel I, transition wheel II change the trend of reversed drag-line, and reversed drag-line is made to be wrapped always in I amplitude changing process of arm
The reversed leveling wheel of network II is without departing from transition wheel III, transition wheel IV change the trend of reversed drag-line, and reversed drag-line is made to become in arm II
During width always the reversed leveling wheel of envelope III without departing from transition wheel IV, transition wheel V change the trend of positive drag-line, make just
