Description
Technical field
The present invention relates to the table top reclining drive device of a kind of Stage elevating platform.
Background technology
The Stage elevating platform of modernization arenas, its table top not only needs have elevating function, the most also needs
Tool tilt function, with abundant stage performance effect.
At present, known to make a certain component tilt the mechanism that used, the most all select tangent
Mechanism or cranking block mechanism.As skylight unlatching some just use tangent mechanism；And dump truck
Tipping bucket discharging just have employed cranking block mechanism.If selecting both mechanisms to drive Stage elevating platform
Table top tilts, then can encounter such a problem: due to the special construction of Stage elevating platform table top
Rectangle wood dragon in face frame on girder steel, then on wood dragon, spread double-deck timber floor so that
Mesa thickness is thicker, that is makes distant from fixed-axis rotation center of table top.So, when
When table top tilts an angle around fixed-axis rotation center rotating, the upper left angle point of its table top also around
Fixed-axis rotation center turns over an equal angular.Due to upper left angle point from fixed-axis rotation center away from
Away from from (radius of gyration is bigger), the arc length turned over is the longest.Owing to Stage elevating platform is with solid
Determine the gap between stage the least (being usually no more than 10mm), therefore when Stage elevating platform table top
During inclination, its upper left angle point will necessarily touch fixing stage, even mutually extruding and cause dance
The destruction of platform platen.
Summary of the invention
In order to overcome above-mentioned present in the table top reclining drive device of existing Stage elevating platform lacking
Falling into, the present invention provides the driving means that a kind of Stage elevating platform table top tilts, and this device can make platform
Plate can be regarded as when inclination flip approx around the rotation of platen upper left angle point, the most also utilizes mechanism
Dead-centre position avoid existing and causing mechanism driving link to destroy because tilting platen falling tendency
Generation.
The technical solution used in the present invention is:
The table top reclining drive device of Stage elevating platform, including stage platen and be arranged on stage platform
Inclined lift mechanism below plate, it is characterised in that: described inclined lift mechanism include slide block,
Arc chute, first connecting rod, second connecting rod and be used for driving one end oscilaltion of stage platen
Lifter；The left end of described stage platen is hinged with described slide block by the first supporting leg,
And the first described supporting leg is vertically fixedly arranged at the bottom of described stage platen；Described slide block
It is arranged in described arc chute and can slide along described arc chute, described circular arc cunning
The center of circle O of groove and described stage platen are in upper left angle point P phase mutual respect during level
Close；The right-hand member of described stage platen is hinged with described lifter；Described first connecting rod
One end is hinged with fixed hinge seat, and the other end is hinged with one end of described second connecting rod, described
Second connecting rod the other end by the second supporting leg hinged with the bottom of described stage platen, and
And the second described supporting leg is vertically fixedly arranged at the bottom of described stage platen；Described stage platform
When plate tilts to put in place, at described first connecting rod and second connecting rod on the same line.
The second described supporting leg is arranged on the center-right position of described stage platen lower edge, institute
The lower end of the second supporting leg stated is hinged with described second connecting rod.
Described lifter includes rack-and-pinion, feed screw nut, electric pushrod or hydraulic cylinder.
Described arc chute, fixed hinge seat and lifter are respectively and fixedly installed in frame.
When ascending motion made by lifter, banking motion just made by platen.If angle of inclination is little
(stage platen angle of inclination is usually no more than 15 °), platen just can be regarded as around it left approx
(because platen is in rotation process, if corner is little, its instantaneous center of velocity just exists the rotation of upper angle point
Near the angle point of platen upper left).Arrange in the center-right position of Stage elevating platform platen lower edge one with
The second supporting leg that platen is vertical, the lower end of the second supporting leg is hinged with second connecting rod, second connecting rod with
First connecting rod is hinged, and two connecting rods are in same linear position when platen tilts and puts in place, now,
Mechanism is in dead-centre position, so that it may avoid causing tooth bar bending failure because tilting platen downslide
Occur.
Beneficial effects of the present invention is embodied in: this device can make table top can approximate when inclination flip
Ground is regarded as around the rotation of table top upper left angle point, breaks to avoid lifting platform and fixed station mutually to extrude
Bad；The most also utilize mechanism dead-centre position to avoid because inclined table glides and cause mechanism former dynamic
The generation of part bending failure.

Fig. 1 is the mechanism kinematic process sketch of the present invention.
Fig. 2 is stage platen mechanism status figure when being in horizontal level.
Fig. 3 is stage platen mechanism status figure when being in obliquity.
Detailed description of the invention
With reference to Fig. 1, the table top reclining drive device of Stage elevating platform, including stage platen 3 He
Being arranged on the inclined lift mechanism below stage platen 3, described inclined lift mechanism includes sliding
Block 1, arc chute 2, first connecting rod 4, second connecting rod 5 and be used for driving stage platen 3
The lifter 6 of one end oscilaltion；The left end of described stage platen 3 passes through the first supporting leg 8
First supporting leg 8 hinged and described with described slide block 1 is vertically fixedly arranged at described stage
The bottom of platen 3；In described slide block 1 is arranged on described arc chute 2 and can be along described
Arc chute 2 slide, the center of circle O of described arc chute 2 and described stage platen 3
Upper left angle point P when being in level overlaps；The right-hand member of described stage platen 3 with
Described lifter 6 is hinged；One end of described first connecting rod 4 is hinged with fixed hinge seat,
The other end is hinged with one end of described second connecting rod 5, the other end of described second connecting rod 5
By second hinged and described with the bottom of described stage platen 3 of the second supporting leg 9
Lower limb 9 is vertically fixedly arranged at the bottom of described stage platen 3；Described stage platen 3 tilts to
