Description

Technical Field

[0001] The utility model relates to the technical field of sector rollers, in particular to a sector roller with a built-in annular flow guide cooling structure. Background Art

[0002] Segment rollers are mainly used in steel mills for rolling steel plates. Segments are the core equipment of steel mills. The correctness of the segment roller array design and the smooth operation of the roller assembly are key factors in ensuring that the steel mills complete processing and production. On the steel plate rolling production line, due to the unsatisfactory cooling effect of the bearing seat in the segment roller assembly, the bearings often fail to reach their designed service life during operation, causing damage to the bearings and further damaging the segment roller assembly. In severe cases, this affects the normal operation of the continuous casting production line and even causes a decline in the quality of the ingot. Inadequate cooling of the bearing seat and roller will aggravate the inadequate lubrication of the bearing. Inadequate cooling of the roller will cause deformation of the roller, which will lead to problems such as bearing jamming and roller failure.

[0003] On this basis, the Chinese patent published by China Patent Publication No. CN205289691U discloses a water-cooled bearing seat for a sector roller of a slab continuous casting machine;

In actual use, the roller is easily deformed due to insufficient cooling, which in turn easily leads to the bearing being stuck and the roller not rotating, thereby reducing the practicality of the device.

[0007] To achieve the above objectives, the present invention provides a technical solution: a sector roller with a built-in annular flow guide cooling structure, comprising a sector roller assembly, bearing seat assemblies are provided on both sides of the sector roller assembly, and oil flow assemblies are provided on the upper ends of the two sets of bearing seat assemblies. A mounting cavity box is provided on one side of the bearing seat assembly, and a sealing through-tube is provided on one side of the mounting cavity box.

[0015] 1. The utility model discloses a sector roller with a built-in annular guide cooling structure. The conventional sector roller is not cooled properly, which will cause the roller to deform, and then lead to the problems of bearing jamming and roller not rotating. In the utility model, the sector roller assembly is assembled with two sets of bearing seat assemblies and put into use. The cooling long pipes arranged at both ends of the sector roller assembly are respectively connected with the two sets of sealing through pipes at corresponding positions. The sector roller assembly is mainly used on the rolling mill of the steel plant for rolling steel plates. When the device is in operation, in order to prevent the temperature of the sector roller assembly from being too high, the operator can pass cooling water into the sealing through pipe at one end. The cooling water will flow into the water inlet end of the cooling long pipe, and then the cooling water will flow through the cooling long pipe to the water outlet end of the cooling long pipe, and then flow out from the other set of sealing through pipes and leave the sector roller assembly. The cooling water passing through the cooling long pipe can cool the sector roller body to prevent its temperature from being too high. The operator controls the time of passing the cooling water into the cooling long pipe according to actual needs. The operation can also allow the cooling water pipe section flowing through the bearing seat assembly to assist in cooling the bearing seat assembly; when the sector roller assembly finishes working, in order to speed up the cooling efficiency of the sector roller assembly, while passing cooling water into the cooling long pipe, the user can also pass cooling water into the water inlet end of the long soft guide cooling pipe. The long soft guide cooling pipe is an annular guide cooling structure, which is evenly wound and distributed on the periphery of the sector roller body. The cooling water will pass through the long soft guide cooling pipe and flow out from the water outlet end of the long soft guide cooling pipe. The cooling water passed into the long soft guide cooling pipe further cools the periphery of the sector roller body, thereby improving the cooling efficiency of the sector roller assembly. After the sector roller assembly cools down and returns to its original state, the cooling water is stopped from being passed into the long soft guide cooling pipe and the cooling long pipe. This setting can simultaneously realize the cooling of the bearing seat assembly and the sector roller assembly, reduce the temperature of the sector roller assembly during operation, enable the roller to operate normally, improve the working stability of the steel mill rolling mill, and increase the service life of the device.

[0016] 2. The utility model discloses a sector roller with a built-in annular guide cooling structure. The bearings installed on the side of the sector roller need to be kept in a good lubrication state during operation. If the lubrication is poor, it will cause problems such as overheating and increased wear of the bearings, and eventually lead to damage to the sector roller. The utility model can lubricate the installation cavity box and the first bearing assembled on the installation cavity box through two sets of oil-passing components. The user can press the sealing disk downward to make the sealing disk shrink into the funnel, and the spring on the spring telescopic rod and the telescopic rod will perform compression movement. At this time, the opening on the top surface of the funnel is opened, and the user can add lubricating oil to the funnel. The oil will flow through the funnel, the main cavity rod and the refueling pipe, and finally the oil will flow along The oil filling pipe enters the inner cavity of the installation cavity box, and the oil flowing into the installation cavity box will lubricate and nourish multiple groups of first bearings, effectively preventing bearing aging; if no oiling is needed, the user releases the pressed sealing disk, and the spring on the spring telescopic rod needs to restore its deformation. The process will generate a restoring force, and the thrust of the spring causes the sealing disk to move upward. At this time, the telescopic rod extends until the sealing disk rises to the opening position on the top surface of the funnel, and the sealing disk then seals the opening to prevent dust and impurities from the external environment from entering the funnel. This setting facilitates users to lubricate the bearings on the device through two sets of oil-passing components, so that the roller will not get stuck due to insufficient lubrication, thereby improving the working efficiency and service life of the device.

[0033] In summary: the utility model discloses a sector roller with a built-in annular guide cooling structure. The cooling of the traditional sector roller is not in place, which will cause the roller to deform, and then lead to the bearing being stuck, the roller not rotating and other problems. In the utility model, the sector roller assembly 3 is assembled with two sets of bearing seat assemblies 1 and put into use. The cooling long pipes 31 provided at both ends of the sector roller assembly 3 are respectively connected to the two sets of sealing through pipes 13 at the corresponding positions. The sector roller assembly is mainly used on the rolling mill of the steel mill for rolling steel plates. When the device is working, During use, in order to prevent the temperature of the sector roller assembly 3 from being too high, the operator can pass cooling water into the sealed through pipe 13 at one end. The cooling water will flow into the water inlet end of the cooling long pipe 31, and then the cooling water will pass through the cooling long pipe 31 and flow to the water outlet end of the cooling long pipe 31, and then flow out from another set of sealed through pipes 13 and leave the sector roller assembly 3. The cooling water passing through the cooling long pipe 31 can cool the sector roller body 32 to prevent its temperature from being too high. The operator controls the time of passing the cooling water into the cooling long pipe 31 according to actual needs. The operation can also allow the cooling water pipe section flowing through the bearing seat assembly 1 to assist in cooling the bearing seat assembly 1; when the sector roller assembly 3 finishes working, in order to speed up the cooling efficiency of the sector roller assembly 3, while passing cooling water into the cooling long pipe 31, the user can also pass cooling water into the water inlet end of the long soft guide cooling pipe 33. The long soft guide cooling pipe 33 is an annular guide cooling structure, which is evenly wound and distributed on the outer periphery of the sector roller body 32. The cooling water will pass through the long soft guide cooling pipe 33 and flow out from the long soft guide cooling pipe 33. The water flows out from the water outlet end, and the cooling water flows into the long soft guide cooling pipe 33 to further cool the periphery of the sector roller body 32, thereby improving the cooling efficiency of the sector roller assembly 3. After the sector roller assembly 3 cools down and returns to its original state, the cooling water is stopped from flowing into the long soft guide cooling pipe 33 and the long cooling pipe 31. This arrangement can simultaneously cool the bearing seat assembly 1 and the sector roller assembly 3, reduce the temperature of the sector roller assembly 3 during operation, enable the roller to operate normally, improve the working stability of the steel mill rolling mill, and increase the service life of the device;

[0034] The bearings installed on the side of the sector roller need to be kept in a good lubricated state during operation. If the lubrication is poor, it will cause problems such as overheating and increased wear of the bearings, and eventually lead to damage to the sector roller. The utility model can lubricate the installation cavity box 11 and the first bearing 12 assembled on the installation cavity box 11 through two sets of oil-passing components 2. The user can press the sealing disk 25 downward to make the sealing disk 25 shrink into the funnel 24, and the spring and the telescopic rod on the spring telescopic rod 27 will perform compression movement. At this time, the opening 26 on the top surface of the funnel 24 is opened, and the user can add lubricating oil to the funnel 24. The oil will flow through the funnel 24, the main cavity rod 22 and the refueling pipe 23, and finally the oil will enter the inner cavity of the installation cavity box 11 along the refueling pipe 23. The oil introduced into the installation cavity box 11 will lubricate and nourish the multiple groups of first bearings 12, effectively preventing the bearings from aging; if no oiling is needed, the user releases the pressed sealing disk 25. At this time, the spring on the spring telescopic rod 27 needs to restore the deformation, and the process will generate a restoring force. The thrust of the spring causes the sealing disk 25 to move upward. At this time, the telescopic rod extends until the sealing disk 25 rises to the position of the opening 26 on the top surface of the funnel 24. The sealing disk 25 then blocks the opening 26 to prevent dust and impurities from the external environment from entering the funnel 24. This setting facilitates the user to lubricate the bearings on the device through two groups of oil-passing components 2, so that the roller will not get stuck due to insufficient lubrication, thereby improving the working efficiency and service life of the device.
