Abstract
The invention relates to an electric lifting platform, which comprises a chassis, a worktable and a shearing furcal arm arranged between the chassis and the worktable, and also comprises a lead screw mechanism, wherein the lead screw mechanism comprises a motor, a speed reduction box, a lead screw and a sliding block; the speed reduction box is pivoted on a middle pivot of the shearing furcal arm; the sliding block is screwed to the lead screw; a lifting wheel capable of freely rotating is arranged on the sliding block; the shearing furcal arm is provided with arc-shaped guide rails; the lifting wheel is clamped between two arc-shaped guide rails; and the opening and closing angle of the shearing furcal arm can be adjusted under the control of the lifting wheel. The electric lifting platform has the characteristic of simple structure. The whole lifting function is finished under the drive of one motor. Moreover, the lead screw has a self-locking function, so that the lifting platform is enabled to keep in a certain horizontal state for a long time.
Description
Technical field
The present invention relates to the elevator technology field, specifically a kind of electric up-down platform.
Background technology
Lifting table commonly used on the present market all is hydraulically powered, and hydraulic-driven has the advantages that to drive great efforts.Also can satisfy the requirement of long-time pressurize in the ordinary course of things, but under some particular environment, still can not satisfy the requirement of use, for example require to remain on for a long time a certain height.This is because how many hydraulic efficiency pressure systems all can exist certain leakage under the situation that remains on a certain state for a long time, causes the height of lifting table work top to reduce.
In some specific operation occasion, be in the consideration of health or safety, do not allow to use the Work tool of hydraulic pressure yet, also need the electric up-down platform of development of new.
Summary of the invention
The object of the present invention is to provide a kind of electric up-down platform, a kind of electric up-down platform by motor-driven novel structure is provided, can satisfy special demand, alternative hydraulic elevating platform uses.
The present invention solves the technical scheme that its technical matters takes: a kind of electric up-down platform, and comprise underframe, bench board and be hinged on the yoke of cutting between the two, it is characterized in that; Also comprise a screw mechanism, described screw mechanism is made up of motor, drop-gear box, leading screw and slide block, and described leading screw process drop-gear box is by motor-driven; Said drop-gear box is articulated on the middle part pivot of cutting yoke; Described slide block screws on leading screw, and the wheel that draws high free to rotate is installed on said slide block, said cut yoke on be provided with on the underarm and the said cooresponding arc-shaped guide rail of wheel that draws high; The curve of arc-shaped guide rail is with the at the uniform velocity up-down of the slide block slip on leading screw changing into bench board; The said wheel that draws high is clipped between two arc-shaped guide rails, under the control that draws high wheel, can regulate the folding angle of cutting yoke, accomplishes elevating function.
The invention has the beneficial effects as follows: the present invention has characteristic of simple structure, and whole elevating function is what under the driving of a motor, to accomplish, and leading screw has auto-lock function, can be long-term make lifting table remain on some horizontalitys not change.Electrically operated elevator is much cleaner with respect to the elevator of fluid pressure type simultaneously, does not also exist hydraulic oil to reveal situation about polluting, and can satisfy some specific (special) requirements in the industry.
Description of drawings
Fig. 1 is a front view of the present invention;
Among the figure: 11 underframe, 12 bench board, 2 cut yoke, 21 middle part pivots, 3 motors, 4 drop-gear boxs, 5 leading screws, 6 slide blocks, 7 draw high wheel, 8 arc-shaped guide rails.
The specific embodiment
As shown in Figure 1; A kind of electric up-down platform; Comprise underframe 11, bench board 12 and be hinged between the two cut yoke 2, the elevator skeleton of this price scissors formula and traditional skeleton are basic identical, different is cutting on the yoke the cooresponding arc-shaped guide rail that is fixed with on the underarm.
Increase by a cover leading screw mechanism; Screw mechanism is made up of motor 3, drop-gear box 4, leading screw 5 and slide block 6, and leading screw 5 by motor-driven, that is to say the rotation of motor-driven screw mandrel through drop-gear box; Drop-gear box 4 is articulated on the middle part pivot 21 of cutting yoke, and motor can be swung like this.Slide block 6 screws on leading screw, and between slide block and leading screw, drop-gear box, guidepost is set, and has good straight-line motion performance.And free to rotate drawing high is installed on slide block 6 takes turns 7; Cut yoke on be provided with on the underarm and the said cooresponding arc-shaped guide rail 8 of wheel that draws high; The curve design of arc-shaped guide rail can be with the at the uniform velocity up-down of the slide block slip on leading screw changing into bench board; Like this, under the control that draws high wheel, can regulate the folding angle of cutting yoke, accomplish elevating function.
Reductor drives the ball-screw rotation; The rotating of motor converts the straight reciprocating motion of slide block into; And then drive and to draw high wheel and roll along arc-shaped guide rail; And then the control folding of cutting yoke, be the at the uniform velocity vertical shifting of bench board with the conversion of motion of horizontal direction, realize the elevating function of lifting table at last.
Except that the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
