For existing drive experiments heavy-duty screw lifting mechanism, its levelness to load-carrying capacity and lifting table there are certain requirements, existing screw-threaded shaft elevator is difficult to reach requirement, due to manufacturing errors and installation error, cause several lead screw pair not at grade, lifting table cannot guarantee level, finally causes experimental result to occur larger error.
Summary of the invention
The object of the invention is in use cannot be in same plane in order to solve existing heavy-duty screw lifting mechanism several screw pairs used, and the problem that the lifting table causing cannot level and the level(l)ing device of a kind of heavy-duty screw synchronous lifting platform of providing.
The level(l)ing device of heavy-duty screw synchronous lifting platform of the present invention is comprised of screw mandrel, screw and spirit level, wherein screw is screwed onto on screw mandrel, screw mandrel and screw are provided with several, mounting hole between screw and lifting table is free-running fit, the bottom of screw is socketed with thrust baring, the upper end of screw is bolted with captive nut, and the top of screw offers several adjustment holes, and spirit level is installed in the resettlement groove on lifting table end face.
Screw is notch cuttype, and thrust baring is socketed in the top of screw lower end step.
The madial wall of captive nut offers square groove, in square groove, be provided with fixed block as the locking device of captive nut, the inner side of fixed block is and nut structure identical inside captive nut, the both sides of fixed block are provided with check screw, by check screw fixed block, can be fixed in square groove, on the sidewall of square groove, be bolted with jackscrew in order to regulate the gap between fixed block and screw.
Principle of work of the present invention:
Several screws of Synchronous lifting or decline lifting table, while eye-level chi, the screw of one end that the bubble of the several spirit levels of lifting table end face of take all tilts is benchmark, both take in several screws vertically highly minimum one be benchmark, with special spanner, embed in the adjustment hole of screw upper end, other screws are rotated to adjusting, keep during this time leading screw motionless, the relative position of other screws is reduced, until the bubble of several spirit levels is all in position, center, now, several screws vertically highly consistent, control process finishes.
In the upper end of all screws, be bolted with the locking device of captive nut and captive nut medial surface, unclamp two check screws on captive nut locking device, unclamping like this captive nut locking device just can moving radially along screw, now by jackscrew bolt tightening, captive nut locking device is pushed up on screw, and the locking process of captive nut finishes.
Beneficial effect of the present invention:
1, make several screws of supporting elevation lifting platform can adjust separately phase angle when mounted, make the end face maintenance level as far as possible of lifting table, thereby reduce experimental error.
2, can make lifting table in lifting process, guarantee the sync rates between several leading screws.
3, fastening owing to adopting captive nut and locking device to carry out, make this screw control apparatus be convenient to installation and removal, and when needed, can unclamp at any time captive nut and carry out screw adjusting.
4, owing to adopting the design of thrust baring and screw ladder, make screw and lifting table supporting seat can bear larger load.
