Abstract

The utility model discloses a replacing mechanism for the thrust bearing of a four high mill, comprising a repairing platform, two guide rails and a traveling car, wherein the height of the repairing platform is identical to that of the bearing base of the support roller, two guide rails that are arranged at a distance from each other are laid on the repairing platform, the traveling car comprises a panel, four roller supports and four rollers, the rollers are disposed on the roller supports through the roller shafts, the four roller supports are respectively arranged at the four corners of the panel, and rollers are on the guide rails and can roll along the guide rails. By utilizing the mechanism of the utility model, the thrust bearing that has been detached can be easily removed from the working position, thereby lowering the labor intensity, improving working efficiency, and avoiding the hidden safety danger in the removing operation.

Description

The replacing frock of four-high mill thrust bearing

Technical field

The utility model relates to a kind of replacing frock of four-high mill thrust bearing.

Background technology

The thrust bearing top of four-high mill connects depresses leading screw, and the bottom connects the supporting roller bearing seat; Depress leading screw to the power of depressing of backing roll by the thrust bearing transmission, so thrust bearing bearing huge pressure, its rolling element is prone to situations such as tired spot corrosion, must make regular check on replacing.Because thrust bearing is from weighing 3t, and be subjected to the restriction of rolling platform, when changing, the thrust bearing maintenance can't utilize driving directly thrust bearing to be hung out, just can hang out on the inspection platform on one side and need utilize chain block to cooperate driving that thrust bearing is exported to, the process need that utilizes chain block to derive thrust bearing expends great amount of manpower, its labour intensity is big, and efficient is low, also exists potential safety hazard in the derivation process.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of replacing frock of four-high mill thrust bearing, utilize this frock the thrust bearing of having dismantled conveniently can be derived the operating position, alleviate labour intensity, improved operating efficiency, avoided the potential safety hazard in the export job.

For solving the problems of the technologies described above, the replacing frock of the utility model four-high mill thrust bearing comprises inspection platform, described inspection platform height is highly consistent with the supporting roller bearing seat, also comprise two guide rails and travelling car, described two guide rails are tiled on the described inspection platform at interval, described travelling car comprises flat board, four wheel carriers and four rolling, described roller is located on the described wheel carrier by wheel, described four wheel carriers are located at four jiaos of described flat board respectively, and described roller is positioned on the described guide rail and along guide rail and rolls.

Derail for guarantee that travelling car is reliably advanced and prevented on guide rail, isosceles triangle can be adopted in above-mentioned guide rail cross section, above-mentioned rollers wheel face shape and described guide rail.

Because the replacing frock of the utility model four-high mill thrust bearing has adopted technique scheme, two guide rails promptly are set on inspection platform, adopt flat board, wheel carrier and roller to make travelling car, the roller of travelling car is positioned on the guide rail and travelling car is advanced along guide rail; Utilize this frock the convenient operating position of deriving of the thrust bearing of having dismantled can have been alleviated labour intensity, improved operating efficiency, avoided the potential safety hazard in the export job.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and embodiments:

Fig. 1 is the structural representation of the replacing frock of the utility model four-high mill thrust bearing,

Fig. 2 derives the schematic diagram of thrust bearing for this frock.

The specific embodiment

As depicted in figs. 1 and 2, the replacing frock of the utility model four-high mill thrust bearing comprises inspection platform 1, described inspection platform 1 height is highly consistent with supporting roller bearing seat 5, also comprise two guide rails 2 and travelling car 3, described two guide rails 2 are tiled on the described inspection platform 1 at interval, described travelling car 3 comprises dull and stereotyped 31, four wheel carriers 32 and four rolling 33, described roller 33 is located on the described wheel carrier 32 by wheel shaft 34, described four wheel carriers 32 are located at described dull and stereotyped 31 four jiaos respectively, and described roller 33 is positioned on the described guide rail 2 and along guide rail 2 and rolls.

Derail for guarantee that travelling car 3 is reliably advanced and prevented on guide rail 2, isosceles triangle can be adopted in above-mentioned guide rail 2 cross sections, above-mentioned rollers 33 wheel face shapes and described guide rail 2 couplings.

The replacing frock of the utility model four-high mill thrust bearing is provided with two guide rails 2 on inspection platform 1, adopt flat board 31, wheel carrier 32 and roller 33 to make travelling cars 3, and the roller 33 of travelling car 3 is positioned on the guide rail 2 and travelling car 3 is advanced along guide rail 2; When this frock is used, at first utilize and depress leading screw 6 thrust bearing 4 lifting certain distances, travelling car 3 is carried out to thrust bearing 4 belows along guide rail 2, utilize again depress leading screw 6 with thrust bearing 4 slow let-downs to the flat board 31 of travelling car 3, remove the relevant connection of thrust bearing 4 and other equipment, adopt chain block or other pulling equipments that travelling car 3 is shifted out along guide rail 2 then, so realize the derivation of thrust bearing 4, implement the replacing operation of thrust bearing 4 from the operating position; Utilize this frock the convenient operating position of deriving of the thrust bearing of having dismantled can have been alleviated labour intensity, improved operating efficiency, avoided the potential safety hazard in the export job.
