Description

Technical Field

[0001] The invention relates to the technical field of bearing seat cooling, and in particular to a cooling device and method for a straightening roller bearing seat of a continuous casting machine. Background Art

[0002] The continuous casting machine can continuously cast high-temperature molten steel into ingots with a certain cross-sectional shape and size specifications. It is one of the common processing equipment for modern steel products. When in use, the rolled material is easily deformed due to repeated bending when passing between the upper and lower rows of staggered rollers. Therefore, straightening rollers are generally equipped to correct shape defects. The bearing seat is one of the components used to install and support the straightening rollers.

[0003] When the existing continuous casting machine straightening roller bearing seat is in use, it needs to withstand great twisting force because it needs to correct the rolled material, which makes the bearing seat easily generate severe high temperature due to friction and the like during operation. At present, workers often use conventional fans or manual sprinkling of water to cool it down. These cooling methods are not stable enough and easily cause the cooling to be not timely, which greatly reduces the service life of the bearing seat. In addition, manual participation is often required, which greatly increases the workload of the staff. Alternatively, special bearing seats with water cooling structures are partially used. However, these methods are not convenient for use with or modification of existing bearing seats, and the structural strength needs to be improved. Summary of the Invention

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] Example 1:

[0037] See also Figures 1-6 As shown, a cooling device for a straightening roller bearing seat of a continuous casting machine includes an enclosing bin 2 arranged outside a bearing seat body 1, with fixed assembly plates 3 installed on both sides of the enclosing bin 2, and assembly screws 4 passing through both ends of the top of the fixed assembly plate 3. The bearing seat body 1 is installed on a designated seat plate on the continuous casting machine. When in use, the enclosing bin 2 is also installed on the seat plate through the assembly screws 4, so that the existing model of the bearing seat body 1 can be modified and used in conjunction with it without damaging the structure of the bearing seat body 1 itself.

[0038] One end of the surrounding bin 2 is connected to a drain pipe 5, and a valve 6 is installed on the outside of the drain pipe 5. An expanded baffle plate 7 is installed on the top of the surrounding bin 2, and the expanded baffle plate 7 and the surrounding bin 2 are made as one. When the bearing seat body 1 is sprayed with water for cooling, the valve 6 is in an open state, and the drain pipe 5 is directly connected to the hot water collection device to ensure that the water flow can be discharged in time. The expanded baffle plate 7 can block the cooling water that spreads outward to prevent it from excessively affecting the surrounding environment;

[0039] An arc-shaped inner rack 8 is installed at one end of the top of the surrounding bin 2, an arc-shaped chute 9 is reserved at the top of the arc-shaped inner rack 8, and a slider 10 is provided inside the arc-shaped chute 9. A first mounting plate 11 is installed on the top of the slider 10, and a second mounting plate 12 is installed on the end of the first mounting plate 11 close to the surrounding bin 2. Both sides of the bottom of the second mounting plate 12 are hinged with a spray head 13, and a spring 14 is connected between the spray head 13 and the second mounting plate 12. When in use, the spray head 13 is connected to the cold water supply device, and water is sprayed to the bearing seat body 1 through the spray head 13 for cooling;

[0040] The first mounting plate 11 is provided with a mounting shaft 16 at the bottom of the side of the surrounding bin 2, and a gear body 17 is installed at the middle position of the outer side of the mounting shaft 16. The cross-sectional shape of the slider 10 is "T"-shaped, and the slider 10 and the arc-shaped slide groove 9 form a relative sliding structure. The central axis of the gear body 17 is parallel to the central axis of the arc-shaped inner rack 8, and the gear body 17 is meshed with the arc-shaped inner rack 8. The mounting shaft 16 and the first mounting plate 11 are connected by a thrust bearing to ensure the stability of the mounting shaft 16 during rotation. When in use, when the mounting shaft 16 rotates intermittently back and forth, the first mounting plate 11 will move back and forth along the arc-shaped inner rack 8, thereby causing the second mounting plate 12 to drive the nozzle 13 to perform a circular motion, thereby realizing intermittent water spray cooling on the top and both sides of the bearing seat body 1, thereby increasing the uniformity of cooling and avoiding damage to the bearing seat body 1 due to different thermal expansion and contraction rates of each part in a long-term uneven cooling state;

[0041] Two groups of bevel gear bodies 18 are installed on the outer side of the mounting shaft 16 away from one end of the surrounding warehouse 2, and a driving mechanism for driving the mounting shaft 16 to rotate is provided on the first mounting plate 11, and the driving mechanism includes a motor 19, which is mounted on the bottom of the first mounting plate 11, and the output end of the motor 19 is connected to the output shaft 20, and the bottom end of the output shaft 20 is installed with an incomplete bevel gear 21, the incomplete bevel gear 21 is perpendicular to the two groups of bevel gear bodies 18, and the incomplete bevel gear 21 is located at a position that meshes with the two groups of bevel gear bodies 18 respectively, so that when the motor 19 drives the incomplete bevel gear 21 to rotate, the half-circle gear block on the incomplete bevel gear 21 will intermittently mesh with one group of the two groups of bevel gear bodies 18, and when the incomplete bevel gear 21 meshes with the two groups of bevel gear bodies 18, it can drive the mounting shaft 16 to rotate in the opposite direction, thereby allowing the mounting shaft 16 to complete the intermittent reciprocating rotation task;

[0042] It should be noted that the number of tooth segments on the incomplete bevel gear 21 is greater than the number of tooth segments on the bevel gear body 18, so that the continuous rotation of the mounting shaft 16 in one direction for more than one circle ensures that the mounting shaft 16 can drive the first mounting plate 11 to move along the arc-shaped inner rack 8 for most of the travel;

[0043] A method for cooling a straightening roller bearing seat of a continuous casting machine, applied to the cooling device for the straightening roller bearing seat of a continuous casting machine according to any one of claims 1 to 9, wherein the specific operating steps are as follows;

[0044] S1: Assembling the device, assembling the surrounding chamber 2 on the mounting plate for supporting the bearing seat body 1, and making the surrounding chamber 2 surround the bearing seat body 1;

[0045] S2: cold water supply, moving the cold water supply device to the vicinity of the device, connecting the nozzle 13 to the cold water supply device, and supplying water to the nozzle 13 through the cold water supply device;

[0046] S3: Sprinkling water for cooling. Water is supplied to the nozzle 13 through the cold water supply device, and sprayed toward the bearing seat body 1 through the nozzle 13 for cooling. At the same time, the motor 19 is turned on. Under the driving force of the motor 19, the nozzle 13 continuously moves during the water spraying process, thereby more fully cooling the bearing seat body 1.

[0047] S4: Maintenance and cleaning. After cooling is completed, clean the interior of the surrounding chamber 2 and the bearing seat body 1, and wipe and dry the residual moisture thereon to avoid erosion of the equipment.

[0048] Example 2

[0049] Based on the above-mentioned embodiment 1, two sets of mounting discs 22 are installed on the outer side of the mounting shaft 16 away from the bevel gear body 18. The top and bottom of the mounting disc 22 near the end of the surrounding chamber 2 are both installed with hemispherical extrusion blocks 23, so that when the mounting shaft 16 rotates, the hemispherical extrusion blocks 23 will intermittently squeeze the nozzle 13, so that the nozzle 13 intermittently adjusts the water spraying angle, thereby allowing the nozzle 13 to more comprehensively spray water to cool the longitudinal portion of the top of the bearing seat body 1;

[0050] A connecting hose 15 is connected to the side of the nozzle 13 away from the mounting shaft 16, and the distance between the two groups of nozzles 13 is greater than the longitudinal length of the bearing seat body 1. The connecting hose 15 replaces the nozzle 13 and is directly connected to the cold water supply device. When the nozzle 13 is moving, the connecting hose 15 will bend and stretch without affecting the movement of the nozzle 13. At the same time, because the distance between the two groups of nozzles 13 is greater than the longitudinal length of the bearing seat body 1, when the nozzle 13 adjusts its angle, there will be a period of time when it is aligned with the end face of the bearing seat body 1, thereby achieving water spray cooling on the end face of the bearing seat body 1, thereby further ensuring comprehensive cooling.

[0051] It should be noted that the mounting plate 22 is located on the side of the nozzle 13 away from the bearing seat body 1, so that when the hemispherical extrusion block 23 squeezes the corresponding nozzle 13, the nozzle 13 can be adjusted inward in angle, thereby ensuring that the nozzle 13 can complete the above-mentioned task of spraying water to cool the end face of the bearing seat body 1. At the same time, multiple groups of hemispherical extrusion blocks 23 can be set on the mounting plate 22 to ensure that the nozzle 13 can adjust the water spray angle back and forth multiple times in a stroke moving along the arc-shaped inner rack 8.

[0052] The working principle of the present invention is as follows: the device is powered by an external power supply. When in use, the cold water supply device is turned on, and cold water is continuously sprayed toward the bearing seat body 1 through the nozzle 13 to achieve a stable cooling task. At the same time, the motor 19 is turned on, and the motor 19 drives the output shaft 20 and the incomplete bevel gear 21 to rotate continuously. As mentioned above, at this time, with the cooperation of the two sets of bevel gear bodies 18, the mounting shaft 16 can complete intermittent reciprocating rotation, and the rotation amplitude in the same direction exceeds one circle. Due to the meshing connection between the gear body 17 and the arc-shaped inner rack 8, the slider 10 can slide in the arc-shaped slide groove 9, so that the first mounting plate 11 will complete reciprocating movement along the arc-shaped inner rack 8, and then the nozzle 13 will reciprocate in a circular motion, so that the top and side of the bearing seat body 1 can be more evenly sprayed with water for cooling;

[0053] Furthermore, when the mounting shaft 16 rotates, as mentioned above, the mounting disc 22 drives the hemispherical extrusion block 23 to intermittently squeeze the corresponding nozzle 13, so that the nozzle 13 intermittently adjusts the water spray angle, thereby further completing a more comprehensive water spray cooling task for the bearing seat body 1;

[0054] After use, the interior of the surrounding chamber 2 can be thoroughly wiped and dried.

[0055] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
