Abstract
The utility model relates to an elevating system and work platform, elevating system, include driving motor, locate lift platform and lifting unit on the vertical slide rail, lifting unit include the main shaft be connected with driving motor, locate main epaxial at least one eccentric wheel and locate the lift platform below and with the corresponding support component of eccentric wheel. The utility model discloses elevating system's the rising and steady, the nothing impact that descends, basic noiselessness and vibration during the elevating system and work platform operation.
Description
Technical field
The utility model relates to mechanical equipment technical field, particularly relates to a kind of lifting mechanism and workplatform.
Background technology
Often can run in reality production, life and need after " frangible object " jacking one segment distance, and then go to get the next one " frangible object ", with the continuous repetition of this action, a series of object can be got.Traditional jacking campaign is coordinate line slideway to realize jacking with cylinder mostly, this kind of mode is difficult to be controlled because the motion of cylinder has impulsive force, easily cause by the damage of " the frangible object " of jack-up, meanwhile, also can with vibration and noise during cylinder up-and-down movement.
Utility model content
The purpose of this utility model is the defect for overcoming prior art, and provides a kind of lifting mechanism and workplatform.
For achieving the above object, the utility model is by the following technical solutions: a kind of lifting mechanism, comprise drive motor, be located at lifting table on vertical slide rail and lifting assembly, described lifting assembly comprises with the main shaft that drive motor connects, is located at least one eccentric wheel on main shaft and is located at support component below lifting table and corresponding with described eccentric wheel.
Further, described eccentric wheel is three, and described main shaft is spaced a distance distribution, and the support component corresponding with described eccentric wheel is also three.
Further, described support component comprises supporting seat and the support wheel be connected with supporting seat by a pivot shaft.
Further, described support component comprises supporting seat and the backup bearing be connected with supporting seat by a pivot shaft.
Further, flower wheel established by described main shaft, described drive motor establishes driving wheel, described driving wheel is connected by belt with flower wheel.
Further, described eccentric wheel is arranged with bearing.
A kind of workplatform, comprise above-mentioned arbitrary described lifting mechanism, the lifting table of described lifting mechanism establishes slide rail, horizontal shifting platform established by described slide rail, described horizontal shifting platform is driven by the ball-screw driven unit be located on lifting table.
The utility model beneficial effect is compared with prior art: 1) rising of lifting mechanism and smooth decreasing, without impacting; 2) basic noiselessness and vibration when lifting mechanism and workplatform running.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the Facad structure schematic diagram of utility model works platform;
Fig. 2 is that the D-D of Fig. 1 cuts open and shows structural representation;
Fig. 3 is the sine waveform figure of eccentric wheel and support wheel or backup bearing points of tangency A kinematic velocity in Fig. 2.
Detailed description of the invention
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment the technical solution of the utility model being introduced further and illustrating.
As shown in Figure 1, for the Facad structure schematic diagram of utility model works platform, Fig. 2 is that the D-D in Fig. 1 cuts open and shows structural representation, a kind of lifting mechanism, comprise drive motor 1, be located at lifting table 3 on vertical slide rail 2 and lifting assembly, lifting assembly comprises with the main shaft 41 that drive motor 1 connects, is located at least one eccentric wheel 42 on main shaft 41 and is located at support component 43 below lifting table 3 and corresponding with described eccentric wheel 42.
Concrete, eccentric wheel 42 is three, and main shaft 41 is spaced a distance distribution, and the support component 43 corresponding with eccentric wheel 42 is also three.
Concrete, support component 43 comprises supporting seat 431 and the support wheel be connected with supporting seat by a pivot shaft or backup bearing 432.
Concrete, 41 main shafts are established flower wheel 44, drive motor 1 is established driving wheel 11, driving wheel 11 is connected by belt 5 with flower wheel 44.
Concrete, eccentric wheel 42 is arranged with bearing.
Lifting table in the utility model, drive motor 1 drives driving wheel 11 successively, flower wheel 44 drives main shaft 41 to rotate, eccentric wheel 42 is followed main shaft 41 and is rotated, and then drive support wheel or backup bearing 432 to rotate, eccentric wheel 42 will do the up-and-down movement of sine curve formula with support wheel or backup bearing 432 points of tangency A, the size of its kinematic velocity is the sine waveform figure shown in Fig. 3, this kind of mode of motion, for being very little by the object impact amount held up, is the mechanism being applicable to very much jacking and putting down " frangible object ".
A kind of workplatform, comprise above-mentioned lifting mechanism, the lifting table 3 of lifting mechanism establishes slide rail 8, slide rail 8 is established horizontal shifting platform 6, horizontal shifting platform 6 is driven by the ball-screw driven unit 7 be located on lifting table 3.This workplatform can complete dipping and heaving, can complete up-and-down movement again, in up-and-down movement process, for being very little by the object impact amount held up, is the workplatform being applicable to very much jacking and putting down " frangible object ".
The above only further illustrates technology contents of the present utility model with embodiment; so that reader is easier to understand; but do not represent embodiment of the present utility model and be only limitted to this, any technology done according to the utility model extends or recreation, all by protection of the present utility model.
