Description
Technical field:
The utility model relates to a kind of platform lifting devices.
Background technique:
During equipment adjusts different production product specifications, the rising-falling tone synchronized to multiple mechanisms is generally required
Section.Using the structure of each mechanism independent-lifting, not only increase the complexity of mechanism, but also it is difficult to ensure that the synchronism gone up and down.
Summary of the invention:
The purpose of this utility model provides a kind of platform lifting device, and the platform lifting device structure is simple, design is closed
It manages, is at low cost, advantageously ensuring that platform synchronous lifting.
To achieve the above objectives, the present invention adopts the following technical solutions:
The utility model platform lifting device, it is characterised in that: including pedestal and several columns being located on pedestal, institute
It states column and is equipped with liftable floating seat, be supported by hoistable platform on the liftable floating seat；Column is distinguished there are four including
It is an active lifting column and three driven lifting columns；Above-mentioned pedestal is equipped with the driving gear driven by driving device,
It is equipped with transmission gear and nut-screw rod mechanism in the active lifting column, is engaged between the transmission gear and driving gear
Intermediate gear, the transmission gear are coaxially connected with drive sprocket, also are provided with nut-screw rod mechanism on three driven lifting columns
With it is coaxially connected by movable sprocket with the screw rod of nut-screw rod mechanism, the drive sprocket and each be arranged with chain on movable sprocket
Item, the liftable floating seat are fixed on the nut of nut-screw rod mechanism.
Further, the tightener sprocket on the outside of chain is acted on there are two setting on above-mentioned pedestal.
Further, above-mentioned pedestal is in four frame shapes, and an active lifting column and three driven lifting columns are set respectively
In the position at four angles of pedestal.
At work, driving device drives driving gear rotation to the utility model platform lifting device, passes through intermediate gear
It is rotated with nutating gear and with the coaxial drive sprocket of transmission gear, drive sprocket passes through each driven lifting column of chain-driving
On rotated by movable sprocket, and then drive the screw rod rotation of each column inner nut screw body, the rotation of screw rod becomes and makes each nut
It is gone up and down with each liftable floating seat being fixed on each nut, and then keeps the hoistable platform being supported on each liftable floating seat real
Existing synchronization lifting.
The utility model platform lifting device simple structure and reasonable design advantageously ensures that hoistable platform realizes synchronous rise
Drop is consistent with adjustable height is guaranteed.
Detailed description of the invention:
Fig. 1 is the D structure schematic diagram of the utility model；
Fig. 2 is that the utility model looks up organigram；
Fig. 3 is the profile construction schematic diagram of active lifting column.
Specific embodiment:
The utility model platform lifting device includes pedestal 1 and several columns 2 for being located on pedestal 1, on the column
Equipped with liftable floating seat 3, hoistable platform 4 is supported by the liftable floating seat；Column is one respectively there are four including
Active lifting column 5 and three driven lifting columns 6；Above-mentioned pedestal is equipped with the driving gear 8 driven by driving device 7, institute
It states and is equipped with transmission gear 9 and nut-screw rod mechanism 10 in active lifting column 5, nibbled between the transmission gear 9 and driving gear 8
Conjunction has intermediate gear 11, and the transmission gear 9 is coaxially connected with drive sprocket 12, also is provided with nut on three driven lifting columns
Screw body 10 and coaxially connected by movable sprocket 13 with the screw rod 17 of nut-screw rod mechanism, the drive sprocket 12 and each passive
Chain 14 is arranged on sprocket wheel 13, the liftable floating seat 5 is fixed on the nut 15 of nut-screw rod mechanism.
Further, in order to avoid there is slip teeth phenomenon, set that there are two the tensionings acted on the outside of chain on above-mentioned pedestal
Sprocket wheel 16, the tightener sprocket 16 are located on telescopically adjustable seat.
Further, in order to which mechanism stable is reliable, above-mentioned pedestal is in four frame shapes, an active lifting column and three from
Dynamic lifting column is respectively provided at the position at four angles of pedestal.
Above-mentioned driving device 7 includes that motor and retarder form, to realize that the deceleration of motor is exported to driving gear 8.
Detection plate 18 is housed on 5 top of active lifting column, the screw rod turnning circle of nut-screw rod mechanism can be detected by photoswitc
Calculate hoistable platform adjustable height.The screw rod of nut-screw rod mechanism is trapezoidal screw, in the device, nut-screw rod mechanism have from
Lock function prevents platform caused by damaging because of mechanism from falling, increases device reliability using self-locking.
At work, driving device drives driving gear rotation to the utility model platform lifting device, passes through intermediate gear
It is rotated with nutating gear and with the coaxial drive sprocket of transmission gear, drive sprocket passes through each driven lifting column of chain-driving
On rotated by movable sprocket, and then drive the screw rod rotation of each column inner nut screw body, the rotation of screw rod becomes and makes each nut
It is gone up and down with each liftable floating seat being fixed on each nut, and then keeps the hoistable platform being supported on each liftable floating seat real
Existing synchronization lifting.
The utility model platform lifting device simple structure and reasonable design advantageously ensures that hoistable platform realizes synchronous rise
Drop is consistent with adjustable height is guaranteed.This kind of platform lifting device is reliable and stable, which is equally applicable to other liftings
Occasion.
The above is only the preferred embodiment of the present invention, it is all done according to present utility model application the scope of the patents it is equal
Deng variation and modification, it should all belong to the covering scope of the utility model.
