Utility model content
For dismantling pressure roller incidental time-consuming, destruction bearing, uneasy congruent problem in prior art manually, the purpose of this utility model is to provide a kind of pressure roller provision for disengagement, time saving and energy saving, handling safety, saving fund, market application foreground is wide.
The technical scheme that the utility model is taked is:
A kind of pressure roller provision for disengagement, it is characterized in that, comprise oil pressure station, oil hydraulic cylinder and provision for disengagement framework, described oil pressure station is connected by high pressure resistant oil pipe with oil hydraulic cylinder, oil hydraulic cylinder fixed head is installed between described oil hydraulic cylinder and provision for disengagement framework, oil hydraulic cylinder fixed head is bolted, the oil hydraulic cylinder expansion link of described oil hydraulic cylinder extends to the cental axial position of provision for disengagement framework, pressure roller to be removed is placed in the inside of described provision for disengagement framework, oil hydraulic cylinder expansion link, under the pressure effect of oil hydraulic cylinder, pushes pressure roller eccentric shaft or bearing completes dismounting.
Further, described provision for disengagement framework is the rectangular structure of inner hollow, and its four sides all offer rectangle hollow out, and its bottom surface is provided with dismounting pressure roller part and portals.
Further, described dismounting pressure roller part portals and is set to circle hole shape, and in it, electrical path length is less than the diameter of pressure roller.
Further, described provision for disengagement framework is by the integral structure of welded steel.
Further, the two sides that described provision for disengagement framework is relative are provided with symmetrical two support columns along axis direction.
Further, the end of described oil hydraulic cylinder expansion link is just to pressure roller eccentric shaft or the bearing of pressure roller to be removed.
The beneficial effects of the utility model are:
The utility model utilizes oil pressure station to provide power, uses scalable oil hydraulic cylinder axle and bearing to be ejected, and when oil hydraulic cylinder applied pressure is greater than the frictional force between pressure roller eccentric shaft (or bearing) and pressure roller shell, can realize the quick-detachment of pressure roller shaft; Firmly evenly, safe ready, use are simple, time saving and energy saving, handling safety, long-range seeing also compare saving fund, unloading process is convenient and swift, 1-2 people just can operation, can effectively avoid violence to dismantle infringement to pressure roller shaft, for enterprise avoid unnecessary economic loss while significantly improve work efficiency.
Provision for disengagement framework in the utility model is by the integral structure of welded steel, play fixation, provision for disengagement framework and oil hydraulic cylinder convenient fixing reliable, the vibrational power flow of provision for disengagement framework is simply novel, make pressure roller be seated in dismounting pressure roller part portal top framework in safe and reliable, provision for disengagement framework is near side shaft and axis direction is provided with symmetrical two support columns, pressure roller is played a supporting role, avoid axial dipole field, easily milling roller can be dismantled, be convenient to timely replacing, maintenance pressure roller, reduce labour intensity, improve operating efficiency.
