Abstract
The invention discloses a fine positioning mechanism for lift doors of an air shower. The fine positioning mechanism comprises a driving shaft driven by motors to rotate, two taking-up wheels and a control circuit, wherein the two taking-up wheels are mounted at the two ends of the driving shaft and achieve ascending and descending of the lift doors by winding and unwinding steel wire ropes; fixed pulleys are arranged above the taking-up wheels and used in cooperation with the taking-up wheels to wind and unwind the steel wire ropes, so the doors can move up and down stably; moreover, frequency converters are adopted to control the band-type brake motors so that adjustable speed and accurate positioning can be achieved; besides, on the basis of an original air shower control function, the film inlet and outlet functions are improved to some extent, and actual operation is further facilitated; steel angles are used for reinforcing supporting frames and supporting guide rails to make the supporting frames and the supporting guide rails not prone to deformation. On the basis that the driving shaft and the taking-up wheels are in jackscrew fit originally, key connection is added, so dislocation of the taking-up wheels is prevented. According to the fine positioning mechanism, a power-off brake is arranged on the driving shaft and can still ensure the braking effect when the band-type brake motors break down, so that the safety of equipment is improved.
