Description

A kind of adjustable hoistable platform in position

Technical field

Engineering machinery technical field of transportation is the utility model is related to, more particularly to a kind of lifting for being used for lifting workpiece is put down Platform.

Background technology

Hoistable platform is a kind of common mechanical structure, and it is primarily used to provide a kind of workbench that can be lifted, existing Having in technology, before workpiece is placed into the supporting plate of hoistable platform, supporting plate is stationarily connected on the support base of downside, The position of workpiece can not be adapted to by adjusting the position of supporting plate, not only wasted time and energy, and the positional precision that workpiece is placed It is not high；Traditional hoistable platform mechanism is mostly driven using hydraulic lifting system, because hydraulic lifting system needs hydraulic cylinder And liquid pump, the lifting stroke of this hoistable platform mechanism are short.

Utility model content

For in the prior art the defects of, the purpose of this utility model is to overcome above-mentioned deficiency of the prior art Place, there is provided a kind of adjustable hoistable platform in position, solve the not high technical problem of positional precision, the position of the utility model supporting plate Fine-tuning, raising positional precision is put, it is time saving and energy saving.

What the purpose of this utility model was realized in:A kind of adjustable hoistable platform in position, including elevating mechanism and open There is the base of holding tank, the elevating mechanism is arranged in holding tank, and transition swivel base, the mistake are provided with above the elevating mechanism Cross on the upside of swivel base and be provided with support base, it is in hollow limit base that the upside of the support base, which is provided with, is set in the hollow region of limit base There is the supporting plate for placing transport object, the supporting plate can move in limit base；The elevating mechanism drives supporting plate Move up and down.

Before utility model works, supporting plate is moved to the position being actually needed；During utility model works, lift Structure drives the motion of transition swivel base, and transition swivel base drives the motion of support base, and support base drives the motion of supporting plate, so as to realize Lift the lifting or decline of workpiece；Supporting plate may move in the utility model, the position that can adjust supporting plate according to being actually needed, Improve the placement location precision of workpiece；The utility model can be applied to lift in the work of workpiece to be docked.

In order to realize the up and down motion of platform, the elevating mechanism includes slewing equipment, and the slewing equipment includes motor, Worm screw is connected with motor, worm gear is connected with worm screw, screw mandrel, the top of base are connected with the inside of worm gear Provided with transition swivel base, the screw mandrel is connected with transition swivel base, and supporting plate is arranged on the upside of support base and can moved on support base； In this design, the linear motion of the rotational movement screw mandrel of worm gear, screw mandrel drives the liter of left/right movement device and switching mechanism Drop motion, it is simple in construction and compact.

In order to improve the mobility of supporting plate, the top of the support base is bracket, is placed with bracket some Stop collar, the stop collar is interior to be provided with rotatable ball, and the edge of the supporting plate is connected with and can be locked in supporting plate Lock in bracket, the lock include lock body, lock core, dead bolt and handle, and the lock body is connected with supporting plate, the upside of lock body with Flushed on the upside of supporting plate, in the groove of lock body bottom, the dead bolt can move up and down the lock bolt sleeve along groove, described Lock core is connected through the center of lock body with handle, and the surrounding of lock core lower central is clinoplain, the clinoplain of the dead bolt It can be fit together with the bottom of lock core；Connecting spring one end, the spring other end and dead bolt on the downside of the groove of the lock body Connection；When the bottom at dead bolt center and the bottom of lock core fit together, dead bolt is pressed in bracket；In this design, just Under beginning state, the clinoplain of dead bolt can be fit together with the bottom of lock core, and dead bolt is pressed in bracket, supporting plate Very light in weight, dead bolt is enough fixed support plate to the pressure of bracket, as long as not rotary handle, supporting plate are pressed on bracket On, the downside of supporting plate and ball are tangent, ball infinite rotational in stop collar so that more laborsaving during mobile supporting plate；When When needing to move supporting plate, rotary handle, rotation of the handle with movable lock core, spring is compressed, when lock core rotates, in inclined plane Under squeezing action, groove of the dead bolt along lock body is moved upwards, and dead bolt leaves bracket, and when 180 ° of rotatable handle, lock is in State is totally released, now, can arbitrarily move supporting plate, limit base limitation supporting plate moves in limit base；Supporting plate is moved Move to, it is necessary to supporting plate is pressed in bracket, rotary handle, lock core rotates, and dead bolt moves downward, together during the position of needs When, the gradual return of spring, spring can also promote dead bolt to move downward, more time saving and energy saving, be locked when handle rotates 180 ° again Tongue and lock core fit together, and lock is in complete locking state, and dead bolt is pressed in bracket.

As further improvement of the utility model, at least two V-shaped racks are interval with the supporting plate；This In design, the longer cylindric workpiece of length can frame on rack, improve the workpiece species that can lift of lifting platform.
