Abstract
The utility model relates to a device for dismounting bearing to support drum head of decoiler used in the industry of examining and repairing machine, comprising an apical plate (1) and a locking nut (2). The apical plate is arranged at the outside of the part between a bearing seat (6) and a central spindle (7) and is screwed tightly by the locking nut. The device for dismounting bearing to support drum head of decoiler also comprises a base plate (3), a hydraulic jack (4) and a double head screw (5). One end of the double head screw is screwed into the threaded hole on the bearing seat, and the other end is fixed by nuts after passing through the holes on the base plate; the hydraulic jack is arranged between the base plate and a central spindle, and the end face of the piston rod at the front part of the hydraulic jack touches the end face of the central spindle. The utility model can dismount the bearing and the bearing seat integrally and reduce the intensity of labor of workers.
Description
Technical field
The utility model relates to the reel of uncoiler head support bearing disassembling device that the machinery overhaul industry is used.
Background technology
The cold rolling 1550CAL unit of Baosteel is the cold rolling advanced technologies equipment of nineteen nineties from external introduction because uncoiler belongs to whole introducing equipment, parts such as reel of uncoiler head support bearing and bearing block before dispatching from the factory assembling and setting finish.After equipment uses a period of time, head bearings must be confirmed in off-line cleaning inspection when reel of uncoiler disintegrated maintenance, because bearing block and fan-shaped block spacing are less only to be about 10mm, during the dismounting bearing, bearing block displacement vertically also is 10mm, bearing still in bearing block, can't be dismantled, and bearing and bearing block can only be carried out integrated removal; Draw the sign indicating number dismounting if use, then quite specification draw a yard pawl, Yin Qila sign indicating number pawl can not effectively be caught bearing block more greatly.And in the data and device-specific instrument that foreign side stays, do not have related data and instrument about reel of uncoiler head support bearing removal.Therefore, generally can only adopt traditional installation and service kit to overhaul, just open or back down with jack with the hammer vibrations, the working time of operating the maintainer like this is very long, and work load is also big, wastes time and energy.
Summary of the invention
The defective that the utility model has overcome that traditional installation and service kit cause workman working time is long and work load is big provides a kind of reel of uncoiler head support bearing disassembling device.This reel of uncoiler head support bearing disassembling device by adopting the effect of pull bar and hydraulic jack, can not only guarantee more easily spring bearing to be disassembled, and can reduce working strength of workers.
The utility model is to realize like this, a kind of reel of uncoiler head support bearing disassembling device, comprise top board and locking nut, top board is installed in the outside of part between bearing block and mandrel, and screw with locking nut, this reel of uncoiler head support bearing disassembling device also comprises bedplate, hydraulic jack and double threaded screw, and an end of double threaded screw screws on the bearing block in the screw, and the other end is fixed with nut after passing aperture on the bedplate; Hydraulic jack is between bedplate and mandrel, and the piston rod end face of its front end contacts with the mandrel end face.
Above-mentioned a kind of reel of uncoiler head support bearing disassembling device, the quantity of double threaded screw is 3-8.
Operation principle of the present utility model is: by the application of top board, bedplate and double threaded screw, top board is installed in case secter pat and slideway etc. move with bearing, use double threaded screw that bearing block and bedplate are fused, hydraulic jack is installed between bedplate and mandrel, and bedplate is parallel with bearing block when adjusting double threaded screw.During hydraulic jack work, the hydraulic jack piston rod is overhanging, withstands mandrel, and bearing and bearing block are moved vertically, separate with mandrel with bearing block until bearing, thereby with bearing and bearing block integral demounting.Bearing and bearing block integral demounting can not only be carried out by application of the present utility model, and working strength of workers can be reduced.
Description of drawings
Fig. 1 is a kind of reel of uncoiler head support bearing disassembling device schematic diagram.
Wherein, 1 is top board, and 2 is locking nut, and 3 is bedplate, and 4 is hydraulic jack, and 5 is double threaded screw, and 6 is bearing block, and 7 is mandrel.
The specific embodiment
The specific embodiment of the present utility model is provided by accompanying drawing.
Referring to shown in Figure 1, a kind of reel of uncoiler head support bearing disassembling device, comprise top board 1 and locking nut 2, top board 1 is installed in the outside of bearing block 6 and 7 parts of mandrel, and screw with locking nut 2, this reel of uncoiler head support bearing disassembling device also comprises bedplate 3, hydraulic jack 4 and double threaded screw 5, and an end of double threaded screw 5 screws on the bearing block 6 in the screw, and the other end is fixed with nut after passing aperture on the bedplate 3; Hydraulic jack 4 is between bedplate 3 and mandrel 7, and the piston rod end face of its front end contacts with mandrel 7 end faces.The quantity of double threaded screw 5 is 3-8.In the present embodiment, when using 5 tons, 10 tons hydraulic jack, between hydraulic jack and bedplate, add the adjustment parallels.
Claims (2)
1, a kind of reel of uncoiler head support bearing disassembling device, comprise top board (1) and locking nut (2), top board (1) is installed in the outside of part between bearing block (6) and mandrel (7), and screw with locking nut (2), it is characterized in that this reel of uncoiler head support bearing disassembling device also comprises bedplate (3), hydraulic jack (4) and double threaded screw (5), one end of double threaded screw (5) screws in bearing block (6) and goes up in the screw, and the other end is fixed with nut after passing aperture on the bedplate (3); Hydraulic jack (4) is positioned between bedplate (3) and the mandrel (7), and the piston rod end face of its front end contacts with mandrel (7) end face.
