Abstract
The invention provides a quick disassembly device for a bearing outer ring in a cold rolled supporting roll bearing pedestal, which comprises a frame type portal frame, a disassembly oil cylinder, a hydraulic pressure station and a lifting platform, wherein the disassembly oil cylinder is fixed on the frame type portal frame; the lifting platform is positioned at the bottom of the frame type portal frame; the hydraulic pressure station provides hydraulic power for the disassembly oil cylinder and the lifting platform. The quick disassembly device has the benefits that the bearing outer ring is pushed out of a bearing pedestal or the bearing outer ring is pressed in the bearing pedestal on the condition that the bearing pedestal is horizontally placed. As an oil press machine is adopted, the thrust is stable, the stroke can be controlled, the efficiency is high, the effects of safety and reliability are realized, the disassembly operation can be completed in about 3 hours, the labor intensity can be reduced, the operation efficiency can be improved, and the service life of the bearing can be efficiently ensured.
Description
Technical field
The invention belongs to the steel rolling field, especially relate to cold-rolling support roll bearing in bearing block outer ring rapid dismounting apparatus.
Background technology
The cold-rolling support roll diameter is all larger, its matching used bearing size is also larger, the main four row cylindrical roller bearings that use, this bearing is the main load bearing component of cold-rolling mill, instructions for use to bearing is stricter, in order to improve the service life of back-up roll bearing, need to regularly change the bearing point of back-up roll bearing, therefore need continually bearing outer ring to be taken out in bearing block, after the transposing bearing point, be reentered in bearing again.The available technology adopting jack carries out dismounting, and disassemble and assemble work need to expend the time of one day, and operating efficiency is low, in addition, in disassembly process, damages bearing outer ring sometimes and causes bearing to scrap.How efficiently and safely bearing outer ring to be taken out to a key point that becomes this field.
Summary of the invention
The problem to be solved in the present invention is to provide cold-rolling support roll bearing in bearing block outer ring rapid dismounting apparatus.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Cold-rolling support roll bearing in bearing block outer ring rapid dismounting apparatus, comprise frame door frame, dismounting oil cylinder, Hydraulic Station and hoistable platform, described dismounting oil cylinder is fixed on described frame door frame, described hoistable platform is positioned at the bottom of described frame door frame, and described Hydraulic Station provides hydraulic power for described dismounting oil cylinder and described hoistable platform.
Further, described dismounting oil cylinder is fixed on the side of described frame door frame.
Further, on described Hydraulic Station, be provided with electric cabinet.
Advantage and good effect that the present invention has are: the technology of the present invention is utilized horizontal press, in bearing block horizontal positioned situation, bearing outer ring is released or bearing outer ring is pressed in bearing block in bearing block.Owing to adopting the oil pressure machine, thrust is steady, stroke is controlled, efficiency is high, safe and reliable, and disassemble and assemble work can complete about 3 hours, and the raising operating efficiency that both can reduce labor intensity can also effectively guarantee bearing service life.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure:
1, frame door frame 2, dismounting oil cylinder 3, Hydraulic Station
4, hoistable platform 5, electric cabinet
The specific embodiment
As shown in Figure 1, the present invention relates to cold-rolling support roll bearing in bearing block outer ring rapid dismounting apparatus, comprise frame door frame 1, dismounting oil cylinder 2, Hydraulic Station 3 and hoistable platform 4, described dismounting oil cylinder 2 is fixed on described frame door frame 1, described hoistable platform 4 is positioned at the bottom of described frame door frame 1, and described Hydraulic Station 3 provides hydraulic power for described dismounting oil cylinder 2 and described hoistable platform 4.
Further, described dismounting oil cylinder 2 is fixed on the side of described frame door frame 1.
Further, on described Hydraulic Station 3, be provided with electric cabinet 5.
The course of work of this example: during dismounting, bearing block is placed on hoistable platform 4, Hydraulic Station 3 is controlled the rising of hoistable platform 4, make bearing block center and the center superposition of dismantling oil cylinder 2, Hydraulic Station 3 gives the dismounting oil cylinder 2 pressurizations, bearing outer ring in bearing block is released, and bearing outer ring drops on hoistable platform 4, and bearing outer ring is after checking, transposing carrying position is placed on hoistable platform 4, by the contraction of dismantling oil cylinder 2, bearing outer ring is pressed in bearing block.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to be used to limiting practical range of the present invention.All equalizations of doing according to the present patent application scope change and improve etc., within all should still belonging to patent covering scope of the present invention.
