The device is characterized by further including a slewing bearing, a connecting base, a rotating base, bearing pedestals and a hinged support, wherein the hinged support is mounted at the upper part of a lifting support and connected with the rotating base; the bearing pedestals are mounted on the two sides on the upper plane of the rotating base; the cylinder body of an oil cylinder is mounted on the bearing pedestals; a piston rod of the oil cylinder is connected with an outer ring of the slewing bearing through the connecting base; and an inner ring of the slewing bearing is connected with a main shaft. According to the invention, as the slewing bearing capable of bearing axial force, radial force and turning torque serves as a transitional connecting device, the structure is simplified, and the reliability of a connecting structure is improved; few elements are adopted, trouble spots are few, the production period is shortened, the production and manufacture cost is low; and site care and maintenance are facilitated.
Description
Technical field
The present invention relates to a kind of rake lifting device of thickener, relate to or rather a kind of rake lifting device of center driving central automatic-rake-lifting thickener.
Background technology
The center driving central automatic-rake-lifting thickener is realized the lifting of mud scraper with the automatic rake-lifting device by the lifting main shaft.The lifting executive component of rake lifting device connects main shaft, and main shaft is ceaselessly rotation at work, if rake lifting device is followed rotation therewith, then the conveying of the power of rake lifting device will be very difficult.For power being provided for lifting executing agency, the general employing at spindle nose of prior art installed a cover transition connecting apparatus, and the lifting executive component is connected with main shaft by transition connecting apparatus, makes the lifting executive component only do movement.Mounting plane thrust bearing and ball bearing in this transition connecting apparatus, and adopt a series of element to realize the location of bearing, fastening, lost efficacy and beat in case spline is moving.This structure not only structure is loaded down with trivial details, and the high process-cycle of cost is long, and bearing be fastened with defective, the inefficacy that often produces relative rotation aborning, lifting spindle difficulty.
Summary of the invention
The object of the invention is to overcome the rake lifting device that the deficiencies in the prior art provide a kind of center driving central automatic-rake-lifting thickener, simplified the structure that main shaft rotates, eliminate additional wear and additional forces, reduce manufacturing procedure, reduce cost, improve the functional reliability of rake lifting device, increase the service life.
The present invention includes transmission device, promote bearing, oil cylinder, main shaft, key; Promote bearing and be installed on the transmission device, characterized by further comprising pivoting support, Connection Block, rotation seat, bearing block, hinged-support, described hinged-support is installed in and promotes bearing top, hinged-support connection of rotating seat; Both sides, plane installation shaft bearing on the rotation seat, cylinder block is installed on the bearing block; The piston rod of oil cylinder is connected with the outer ring of pivoting support by Connection Block, and the inner ring of pivoting support connects main shaft.
The present invention adopts the pivoting support that can bear axial force, radial load and turning torque as transition connecting apparatus, simplified structure, the reliability of raising syndeton; The Internal and external cycle of described pivoting support can relatively rotate.
Operation principle:The present invention comes the flexible lifting spindle of realizing of pushing piston bar by the oil extraction of advancing in two chambeies of oil cylinder.During thickener work, main shaft rotates under actuator drives, drives the pivoting support inner ring and rotates, and the outer ring is static, thereby guarantees that oil cylinder does not rotate.When main shaft need to rise, oil cylinder the chamber oil-feed of bar bar arranged, the rodless cavity oil return, piston rod rises, and drives main shaft and rises.When main shaft need to descend, the rodless cavity oil-feed of oil cylinder, the rod chamber oil return, piston rod stretches out, and drives main shaft and descends.Certain gap that is combined with owing to main shaft, might certain beat be arranged along the tangential or normal direction of key when scraping mud, this moment, oil cylinder can swing around hinged-support, the oil cylinder axis is overlapped with main-shaft axis all the time, eliminated the additional component that produces because of main shaft and piston rod decentraction, guaranteed that rake lifting device can successfully work.
As shown from the above technical solution, beneficial effect of the present invention
:1, adopt pivoting support to simplify the structure that main shaft rotates; 2, pivoting support can either bear axial force again can bearing radial force and turning torque, reliability is high; 3, oil cylinder can swing around hinged-support, makes piston rod center and the alignment of shafts all the time point-blank; 4, the element of structure employing is few, and the trouble point is few, and the production cycle shortens, processing and low cost of manufacture; 5, be convenient to on-the-spot maintenance.
Description of drawings
Accompanying drawing is structural representation of the present invention.
Among the figure, 1. main shaft, 2. pivoting support, 3. Connection Block, 4. the bearing pin I 5. promotes bearing, 6. bearing pin II, 7. rotation seat, 8. bearing block, 9. oil cylinder, 10. transmission device, 11. keys, 12. hinged-supports, 13. cylinder pedestals.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
As shown in drawings, as shown in drawings, the present invention is comprised of main shaft 1, pivoting support 2, Connection Block 3, bearing pin I 4, lifting bearing 5, bearing pin II 6, rotation seat 7, bearing block 8, oil cylinder 9, transmission device 10, key 11, hinged-support 12, cylinder pedestal 13 etc.Described hinged-support 12 is installed in the top that promotes bearing 5, and hinged-support 12 is by bearing pin II 6 connection of rotating seats 7; Both sides, plane installation shaft bearing 8 on the rotation seat 7, oil cylinder 9 cylinder bodies are installed on the bearing block 8 of rotation seat 7 both sides.
Described pivoting support 2 is transition connecting apparatus, and it can bear axial force, radial load and turning torque, and inside and outside circle can relatively rotate, and its inner ring connects main shaft 1, and the outer ring connects the piston rod of oil cylinder 9 by Connection Block 3.The inferior part of the cylinder block of described oil cylinder 9 is with base 13, and base 13 both sides are with bearing pin, and bearing pin is contained in the bearing block 8 of rotation seat 7 both sides.
Described Connection Block 3, bearing pin I 4 form a revolute pair with the piston rod of oil cylinder 9, and the piston rod of oil cylinder 9 can rotate around bearing pin I 4.
Described bearing block 8, oil cylinder 9 form a revolute pair, and oil cylinder 9 can rotate around the center line of bearing block 8.
Described lifting bearing 5, bearing pin II 6, rotation seat 7 form a revolute pair, and rotation seat 7 can rotate around bearing pin II 6.
When main shaft 9 needs to rise, the rod chamber oil-feed of oil cylinder 9, the rodless cavity oil return, piston rod rises, and drives main shaft 9 and rises.When main shaft 1 needs to descend, the rodless cavity oil-feed of oil cylinder 9, the rod chamber oil return, piston rod stretches out, and drives main shaft 1 and descends.Certain gap that is combined with owing to main shaft 1, key 11 and transmission device, main shaft 1 has certain beat with key 11 along the tangential or normal direction of key 11 when scraping mud, this moment, oil cylinder 9 can swing around rotating sub-center by several revolute pairs, make oil cylinder 9 axis all the time with main shaft 1 dead in line, additional component that the piston rod decentraction because of main shaft 1 and oil cylinder 9 produces and the heel and toe wear of oil cylinder 9 inner carrier sealing rings have been eliminated, increase the service life, guarantee that the present invention can successfully work.
