Further, described synchronous lifting upper plate is also fixed together with a fixed head of outer, described fixed head is provided with fixed bar, described fixed bar is connected with stroke dog, in running, limit gear ring lifting stroke by stroke dog.
Further, described gear ring cover and gear ring lifting are provided with bearing between overlapping.
Further, the output shaft of described lifting reducing motor is provided with lifting driving gear, described lifting driving gear engages and drives lifting idle pulley, and described lifting idle pulley engages and drives lifting external toothing.
Further, described lifting external toothing engages and drives the multiple lifting gears being distributed in its edge.
Further, described fixed bar is connected with multiple stroke dog, and sets the bound extreme position of gear ring by the position adjusting described stroke dog.
The invention has the beneficial effects as follows:
The present invention compares with above several lifting mode and has the following advantages:
Compared with the first, owing to adopting the up-down mode of cylinder actuating cam, the height and position of gear ring can only by adjust cylinder Limit screw position carry out regular manual adjustment.
Compared with the second, adopt Chain conveyer to drive three screw pairs, due to Chain conveyer poor stability, transmission accuracy is low, easily forms synchronizing bar asynchronous, cause gear ring lifting to be overlapped stuck in lifting process.
Comprehensively above-mentioned.This constitutional detail is simple, processing, easy to assembly, and lifting transmission accuracy is high, and reliability is high, economical and practical.
