Abstract
The invention discloses a driving and rake lifting device of a thickener. The driving and rake lifting device is characterized in that a rake lifting device and a driving device are two mutually independent devices, wherein when mud needs to be scraped, only a motor needs to be started; when a rake needs to be lifted up or fall down, only a cylinder needs to be internally filled with hydraulic oil; the two operations do not interfere with each other; and the mud can also be scraped simultaneously when the rake is lifted steadily. The rake lifting device is lifted up or falls down by virtue of a hydraulic system. A driving shaft of the driving device is supported by rolling bearings; one end, along the axis, of the driving shaft is provided with a thrust bearing; the driving shaft is connected with a motor direct-connection type speed reducer at the upper part of the driving shaft through a coupler, and therefore a traditional worm gear speed reducer is omitted, not only is the structure simplified, but also the driving efficiency is enhanced.

Preferably, transmission device is driven by cycloidal planetary gear speed reducer.
Preferably, a whole set of transmission device is arranged on bearing body, by the effect of hydraulic pressure, promotes the lifting of bearing body, realizes the lifting of a whole set of transmission device, realizes and carries rake.
Preferably, piston is installed on bearing body, its outer cover has cylinder sleeve, and bearing body, piston, cylinder sleeve have formed a double acting hydraulic cylinder.
Preferably, rake is arranged on the bottom of power transmission shaft, and power transmission shaft is by upper and lower two secondary roller bearings, bearing radial force, and rolling bearing is arranged in bearing body.
Preferably, a secondary thrust ball bearing is installed at the top of bearing body, bears axial force.
Preferably, cycloidal planetary gear speed reducer is fixed on the top of bearing body by support.
Preferably, secondary thrust ball bearing and a back-up ring is installed on power transmission shaft top, this thrust ball bearing is arranged on the top of bearing body.
Preferably, motor direct-connection type reductor is fixed on the top of bearing body by support.
Preferably, the cylinder body of hydraulic system is fixed on crossbeam, is also fixed with lead on crossbeam top, processes porosely to match with lead on bearing body.
According to the present invention, remove huge worm-gear speed reducer, simple in structure, easy to maintenance.
According to the present invention, to carry rake and adopt hydraulic pressure lift, power transmission shaft is no longer raised, and changes employing roller bearings into, will carry rake and separate with two devices of transmission, has promoted the transmission efficiency of transmission device, has reduced load.
According to the present invention, what transmission device adopted is that cycloidal planetary gear speed reducer drives, and power transmission shaft adopts rolling bearing to support, resistance while having reduced widely original employing sliding bearing, because the transmission efficiency of cycloidal planetary gear speed reducer reaches more than 0.9, transmission efficiency is high, and simple in structure.
According to the present invention, rake lifting device has adopted hydraulic pressure to carry rake, realizes the lifting of rake by promoting the mode of a whole set of transmission device, promotes steadily, simple in structure, easy to maintenance.
