It is to use one or more screw synchronous to drive, to lift several tons or even the weight of tens of tons.
For existing drive experiments heavy-duty screw elevating mechanism, it is to bearing capacity and the water of hoistable platform
Pingdu there are certain requirements, and existing screw-threaded shaft elevator is extremely difficult to requirement, due to foozle and alignment error,
Causing several lead screw pair the most at grade, hoistable platform cannot ensure level, ultimately results in experimental result
Bigger error occurs.
Summary of the invention
The invention aims to the several screw pairs solved used by existing heavy-duty screw elevating mechanism make
Cannot be in approximately the same plane during with, and the hoistable platform caused cannot the problem of level and the one that provides
The level(l)ing device of heavy-duty screw synchronous lifting platform.
The level(l)ing device of heavy-duty screw synchronous lifting platform of the present invention is by screw mandrel, screw and water
Leveling ruler forms, and wherein screw is screwed onto on screw mandrel, and screw mandrel and screw are provided with several, screw and hoistable platform it
Between installing hole be matched in clearance, the bottom of screw is socketed with thrust bearing, and the upper end of screw is bolted with fixing
Nut, the top of screw offers several adjustment hole, and horizon rule is installed in the resettlement groove on hoistable platform end face
In.
Screw is notch cuttype, and thrust bearing is socketed in the top of screw lower end step.
The madial wall of fixing nut offers square groove, is provided with the fixed block locking dress as fixing nut in square groove
Put, the inner side of fixed block be with fixing nut inside identical nut structure, the both sides of fixed block are provided with fixing
Screw, can be fixed in square groove by fixed screw fixed block, the sidewall of square groove is bolted with jackscrew and uses
With the gap between regulation fixed block and screw.
The operation principle of the present invention:
Synchronous lifting or several screws of decline hoistable platform, eye-level chi simultaneously, with hoistable platform end face
On the basis of the screw of one end that the bubble of several horizon rules all tilts, both with minimum in several screws
One on the basis of, embed with special spanner in the adjustment hole of screw upper end, other screws rotated
Regulation, period keeps leading screw motionless, is reduced the relative position of other screws, until the gas of several horizon rule
Bubble is all in position, center, and now, several screws the most highly consistent, regulation process terminates.
It is bolted with fixing nut and the locking device of fixing nut medial surface in the upper end of all screws, unclamps solid
Determining two fixed screws on nut anti-looseness device, so unclamping fixing nut anti-looseness device just can be along silk
Female moves radially, and is now tightened by jackscrew bolt, makes fixing nut anti-looseness device top to screw, fixes
Nut anti-looseness process terminates.
Beneficial effects of the present invention:
1, the several screws making support hoistable platform lift can individually adjust phase angle when mounted, makes hoistable platform
End face keep level as far as possible, thus reduce experimental error.
2, hoistable platform can be made to ensure the sync rates between several leading screw in lifting process.
3, owing to using fixing nut to fasten with locking device, make this screw adjusting means be easily installed and
Dismounting, and when needed, fixing nut can be unclamped at any time and carry out screw regulation.
4, owing to using thrust bearing and the design of screw ladder, enable screw and hoistable platform to support seat and hold
By bigger load.

Detailed description of the invention
Refer to shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4:
The level(l)ing device of heavy-duty screw synchronous lifting platform of the present invention is by screw mandrel 1, screw 2 and
Horizon rule 3 forms, and wherein screw 2 is screwed onto on screw mandrel 1, and screw mandrel 1 and screw 2 are provided with four, screw 2
And the installing hole between hoistable platform 4 is matched in clearance, the bottom of screw 2 is socketed with thrust bearing 5, screw
The upper end of 2 is bolted with fixing nut 6, and the top of screw 2 offers several adjustment hole 7, and horizon rule 3 is installed
In resettlement groove on hoistable platform 4 end face.
Screw 2 is notch cuttype, and thrust bearing 5 is socketed in the top of screw 2 lower end step.
The madial wall of fixing nut 6 offers square groove 8, is provided with fixed block 9 as fixing nut 6 in square groove 8
