Description

Technical Field

[0001] The invention relates to the field of rolling mill bearing assembly, and in particular to an installation device for replacing an inner sleeve of a roller bearing. Background Art

[0002] In the assembly of rolls in narrow strip steel production, the installation of the roll inner sleeve is a very dangerous task. Traditionally, workers wear gloves to take and install, which often leads to burns and injuries.

[0003] Therefore, it is necessary to develop a new type of installation device to overcome the above problems. Summary of the invention

[0004] Purpose of the invention: In view of the shortcomings and defects of the prior art, the present invention provides an installation device for replacing the inner sleeve of a roller bearing, which replaces the work of workers wearing gloves to take and install the hot inner sleeve of the roller bearing and install it on the roller, and uses a trolley to install the bearing inner sleeve, thereby eliminating safety hazards.

[0005] Technical solution: The present invention is an installation device for replacing the inner sleeve of a rolling mill bearing, which is characterized by comprising a lifting screw with a crank handle on the top of the lifting screw. The lifting screw drives the lifting nut to rotate to raise or lower the inner sleeve of the rolling mill bearing, thereby aligning the inner sleeve of the rolling mill bearing with the rolling mill.

[0006] Wherein, the lifting screw rod extends into the trolley, and the trolley is provided with a trolley rear guard plate and a bottom plate.

[0007] Wherein, a plurality of trolley handrails are arranged on the top of the trolley.

[0008] Wherein, the bottom plate of the trolley is provided with a plurality of trolley push wheels.

[0009] Wherein, the bottom of the lifting screw rod is connected with the inner sleeve taking support plate through a screw rod fixing cover.

[0010] Wherein, the bottom of the inner sleeve taking-out pallet is connected to the bottom plate via two inner sleeve taking-out pallet slide rails.

[0011] Among them, the two inner sleeve pallet slide rails are arranged in parallel.

[0012] Wherein, the inner sleeve of the rolling mill bearing is connected to the inner sleeve bracket.

[0013] Wherein, the number of the trolley push wheels is 4.

[0014] When in use, the inner sleeve bracket adjusts the height of the inner sleeve taking pallet by shaking the handle to make the lifting screw rise and fall, lift the inner sleeve of the rolling mill bearing heated by the bearing heater, and then take out the inner sleeve of the rolling mill bearing through the sliding friction movement of the inner sleeve taking pallet slide rail and put it back on the bottom plate close to the rear guard plate of the trolley. After it is stable, push the trolley to the flat area of ​​the roller by holding the handrail of the trolley, and then use the upgraded screw to align the center of the inner sleeve of the rolling mill bearing with the center of the roller, push the inner sleeve taking pallet to install it on the roller, and complete the installation task.

[0015] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: From the perspective of safety, the present invention sets up safety designs such as a trolley rear guard plate, an inner sleeve bracket and an inner sleeve pick-up tray, thereby avoiding contact between people and the high-temperature bearing inner sleeve. The present invention improves the workers' operating mode and reduces the scalding and smashing incidents that occur when workers take and install the hot roller inner sleeve.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0019] The installation device for replacing the inner sleeve of a rolling mill bearing of the present invention comprises a lifting screw 2, a crank 1 is provided at the top of the lifting screw 2, and the lifting screw 2 drives the lifting nut 6 to rotate so that the inner sleeve 5 of the rolling mill bearing rises or falls, and the inner sleeve 5 of the rolling mill bearing is aligned with the rolling mill. The lifting screw 2 extends into the trolley, and the trolley is provided with a trolley rear guard plate 4 and a bottom plate 10. A plurality of trolley handrails 3 are provided on the top of the trolley. The bottom plate 10 of the trolley is provided with a plurality of trolley push wheels 11. The bottom of the lifting screw 2 is connected to the inner sleeve removal support plate 8 through a screw rod fixing cover 12. The bottom of the inner sleeve removal support plate 8 is connected to the bottom plate 10 through two inner sleeve removal support plate slide rails 9. The two inner sleeve removal support plate slide rails 9 are arranged in parallel. The inner sleeve 5 of the rolling mill bearing is connected to the inner sleeve bracket 7. The number of the trolley push wheels 11 is 4.

[0020] When in use, the inner sleeve bracket 7 adjusts the height of the inner sleeve taking support plate 8 by shaking the crank handle 1 to make the lifting screw rod 2 rise and fall, lift the rolling mill bearing inner sleeve 5 heated by the bearing heater, and then take out the rolling mill bearing inner sleeve 5 through the sliding and friction movement of the inner sleeve taking support plate slide rail 9 and put it back on the bottom plate 10 close to the rear guard plate 4 of the trolley.
