Abstract
The utility model discloses a motor-driven lifting platform which comprises a chassis, a working platform, a scissor-type arm which is arranged between the chassis and the working platform and a lead screw mechanism which is composed of a motor, a reducer casing, a lead screw and a sliding block. The reducer casing is connected on a pin of the middle portion of the scissor-type arm in pivoting mode, and the sliding block is arranged on the lead screw in rotating and combining mode. A hauling wheel which can freely rotate is arranged on the sliding block, and arc-shaped guide rails are arranged on the scissor-type arm. The hauling wheel is arranged between the two arc-shaped guide rails in clamping mode, and under the control of the hauling wheel, an opening angle of the scissor-type arm can be adjusted. The motor-driven lifting platform has the advantages of being simple in structure. Through the driving of the motor, a whole lifting function is achieved. The lead screw has a self-locking function so that the lifting platform can be kept in a certain level condition without being changed in a long time.
Description
Technical field
The utility model 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.
The utility model content
The purpose of the utility model is to provide a kind of electric up-down platform, and a kind of electric up-down platform by motor-driven novel structure is provided, and can satisfy special demand, and alternative hydraulic elevating platform uses.
The technical scheme that its technical matters of the utility model solution is taked is: a kind of electric up-down platform; 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; By motor-driven, said drop-gear box is articulated on the middle part pivot of cutting yoke described leading screw through drop-gear box, and 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, accomplish elevating function.
The beneficial effect of the utility model is: the utlity model has characteristic of simple structure; Whole elevating function is 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 the front view of the utility model;
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.
