Hoistable platform is to be mainly used for industrial and mining enterprises' production line and warehouse, code using a kind of extremely extensive mechanical equipment
Head conveying articles.Currently, the jacking system that platform uses mainly has screw rod jacking system and hydraulic lifting system.Screw rod lifting system
System is to be converted into moving along a straight line by the rotary motion of screw rod using motor deceleration mechanism and screw thread pair, and screw rod is allowed axially to move
It is dynamic, multiple screw rod lifting devices are configured in multiple points of platform, so that entire platform be allowed to realize lifting effect.But this system bulk
Greatly, there is certain oneself height, need larger auxiliary stroke, especially foundation construction amount is big, and limited occasion can not be complete in space
At related needs.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of high-precision multistage screw rod liter is provided
Platform structure drops, which reaches high-precision lift work, and is able to satisfy in small space and cannot dig the occasion use of ground.
A kind of in order to achieve the above purposes, the technical solution adopted by the utility model is: high-precision multistage screw rod hoistable platform
Structure includes framework platform, first bearing, spacer, drive sprocket, second bearing, the first screw rod, the first feed screw nut,
Two screw rods, the second feed screw nut, third screw rod, third feed screw nut, driving motor, driving chain；The framework platform is to rise
The hardened structure of working platform plane framework drops, which is provided with a lead screw transmission mechanism；It is described
Be equipped with first bearing at the top of lead screw transmission mechanism, which is end face thrust ball bearing, first bearing by bearing block with
Framework platform connection；The first bearing is coupled with the first screw rod, be equipped between the first bearing and the first screw rod every
Set；The drive sprocket is mounted under spacer；The drive sprocket bottom is equipped with second bearing, which is deep-groove ball
Bearing；The first feed screw nut of the first screw rod housing, the first screw rod and the first feed screw nut form step of threads pair；Described
One feed screw nut outer ring also serves as the second screw rod, the second feed screw nut composition second level screw thread pair of the second screw rod and housing；Third silk
The three-level screw thread pair housing of bar and third feed screw nut composition is in second level screw thread pair outer ring；The driving motor setting is flat in frame
In the middle part of platform bottom surface, which connect with framework platform bottom surface rigid flange；The driving chain is connected to four groups of screw rods and passes
Between the drive sprocket and driving motor of motivation structure.
The beneficial effects of the utility model are: the structure reaches high-precision lift work, and it is able to satisfy in small space and not
The occasion that ground can be dug uses.
