Abstract
The utility model provides a disassembling device of a bearing seat of a supporting roller of a rolling mill, which comprises a translational loop wheel machine which is driven by a driver and a placing platform used for placing a supporting roller. The utility model is characterized in that the upper part of the placing platform is provided with a carrying roller and supporting frame of a supporting roller; the lower part of the placing platform is provided with a lifter. The utility model has the advantage of simple structure, besides, the problems of bearing capacity, rigidity and deformation, etc. are solved; therefore, frictional force and resistance force in the processes of disassembly and installation are reduced to a low level, damage caused by the interaction of a rolling body and an inner ring is effectively avoided, and simultaneously, in the installation, the utility model is favorable for the centering of a bearing seat. The control precision of disassembly and the installation is improved to caused the error to be in the range of 0.025 mm; the automation and the electrification controlled by the disassembly and the installation can be realized; the uniformity of an upper gap and a lower gap of the inner ring between the inner ring and the rolling body of a bearing are ensured. Therefore, the utility model is an ideal and practical disassembling device of a bearing seat of a supporting roller of a rolling mill.
Description
Technical field
The utility model relates to a kind of provision for disengagement, especially a kind of provision for disengagement of milling train supporting roller bearing seat being carried out dismounting.
Background technology
In the steel rolling production process, the backing roll that matches with milling train just can produce wearing and tearing after using a period of time, must recover the roll surface precision to roll surface grinding again like this, makes it to reach the surface roughness of 0.8 μ m.And during the grinding roll surface, all bearing on the backing roll and bearing block will be pulled down, being about to bearing inner race separates with the outer assembly bearing seat of rolling element, again bearing and bearing block is installed on the backing roll after grinding finishes again.Because Support roller assembly weight is 102 tons (Fig. 1), the bearing fit clearance only is 0.5mm, and centering is had relatively high expectations in bearing removal, installation process, therefore, use special provision for disengagement to dismantle bearing and bearing block.Existing provision for disengagement is made up of hoist cylinder, voussoir, platform for placing, translation oil cylinder, hydraulic system etc., when with its dismounting supporting roller bearing seat, there is following defective: 1, complex structure, the bearing capacity deficiency, easily cause the platform distortion, can't guarantee that in lifting process the bearing enclose gap is even.2, hydraulic cylinder push-and-pull voussoir is adopted in provision for disengagement, and the lower wedge block contact-making surface is changed in lifting process, and last voussoir end face can not remain level, the requirement that can't guarantee to dismantle precision in motion process.3, positioning accuracy is inaccurate, adjustable height will by operating personnel according to the observation the distance of bearing block and backing roll carry out decision operation.These design defect easily cause dismounting, supporting roller bearing seat difficulty are installed, and very easily causing the large-scale precision rolling bearing of value 1,000,000 to pull, scratch in the installing/dismounting, inefficiency has a strong impact on backing roll grinding and assembling, drag slow rhythm of production, become the bottleneck that restriction is produced.Therefore, be necessary prior art is improved.
Summary of the invention
For overcoming above-mentioned many deficiencies that prior art exists, it is a kind of simple in structure, easy to operate, flexible that the utility model provides, and contraposition is accurate, the milling train supporting roller bearing seat provision for disengagement that installation accuracy is high.
The utility model is realized by following technical proposal: the provision for disengagement of a kind of milling train supporting roller bearing seat, comprise translation chassis and the platform for placing of putting backing roll by driver drives, the top that it is characterized in that platform for placing is equipped with carrying roller and is supported the carriage of carrying roller, and lifter is equipped with in the below.So that hold backing roll by platform for placing, the liter of finishing backing roll simultaneously with fall.
The lifter of described platform for placing below comprises hoist cylinder that is positioned at its middle part and fixed guide and the slide plate that is positioned at its both sides, wherein the piston tip of hoist cylinder links to each other with platform for placing, fixed guide is connected as a single entity with the base plate that is fixed on ground, slide plate places on the guide rail, and the upper end and the platform for placing of slide plate are connected as a single entity, so that under hoist cylinder drives, make draw runner along the upper and lower slip of fixed guide, the liter of finishing platform for placing with fall.
The carrying roller that described platform for placing top is provided with is made as two at least, each carrying roller places respectively on the corresponding carriage, so that hold backing roll by carrying roller, backing roll can be rotated by carrying roller, it is the rotational support roller that thereby backing roll is left standstill in change, make the friction of interior rolling element of bearing block and inner ring become rolling friction, effectively reduce mutual wearing and tearing by sliding friction.
Described translation chassis is made of sliding platform and rail chair that supports sliding platform and the driver that is installed on the rail chair, wherein driver is a driving oil cylinder, the pistons end of this oil cylinder links to each other with sliding platform by contiguous block, so that under hydraulic oil cylinder driving, sliding platform is moved horizontally along rail chair.
The utility model compared with prior art has following advantage and effect: adopt such scheme, promptly on platform for placing, be provided with idler assembly and lifter, on the translation chassis, only be provided with horizontal shifting platform, both simplified the structure, solved bearing capacity again, problem such as rigidity and distortion, make dismounting, frictional force in the installation process, resistance drop is to reduced levels, the damage of effectively avoiding the interaction because of rolling element and inner ring to cause, the centering that helps simultaneously bearing block when mounted, improve dismounting, control accuracy is installed, make error only be ± 0.025mm, can realize dismounting, the automation of control is installed, electrified, guaranteeing bearing roller and the inner ring uniformity in gap up and down, therefore, is a kind of comparatively desirable, practical milling train supporting roller bearing seat provision for disengagement.
Description of drawings
Fig. 1 is the structure chart of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As figure, 1 is backing roll, 2 is the bearing block at backing roll two ends, 3 is bearing roller, 4 is bearing inner race, by the utility model with bearing block 2, rolling element 3 is pulled down, so that backing roll 1 is polished and is repaired, structure of the present utility model is as follows: the translation chassis is made as two, its sliding platform 5 places on the rail chair 7, and can slide along rail chair 7, rail chair 7 sides are installed and are driven oil cylinder 6, the pistons end of oil cylinder 6 links to each other with sliding platform 5 by contiguous block 8, by stretching of oil cylinder 6, make sliding platform 5 move left and right, the dress of realizing bearing block 2 and bearing 3 with unload, both sides, platform for placing 9 below are connected with slide plate 10, this slide plate 10 places on the guide rail 11, and guide rail 11 is connected as a single entity with base plate 12, and hoist cylinder 15 places middle part, platform for placing 9 belows, its piston 14 ends link to each other with platform for placing 9, connect a position sensor 13 in the piston bottom, with accurate mensuration lifting position, the top of platform for placing 9 is installed four corresponding carrying rollers 16 respectively by four carriages 17, so that hold backing roll 1, and make it to rotate thereon.
