DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Specific embodiments are given below.
[0024] Such as Figures 1 to 3As shown in the figure, a device for cleaning the oxide scale on the surface of a roll according to an embodiment of the present utility model includes an operating table 1; a pair of fixing blocks 11 are fixedly connected to the top of the operating table 1; a hydraulic cylinder 12 is fixedly connected to the middle of the fixing block 11; a pair of connecting plates 13 are fixedly connected to the side wall of the hydraulic cylinder 12; a fixing frame 14 is fixedly connected to the top of the fixing block 11; a pair of brackets 15 are hinged to the inner side wall of the fixing frame 14; a first roller 16 is fixedly connected to the end of the bracket 15; a third roller 112 is fixedly connected to the end of the bracket 15 away from the first roller 16; the third roller 112 is in contact with the side wall of the connecting plate 13; a second roller 17 is fixedly connected to the top of the hydraulic cylinder 12; a first electric push rod 18 is fixedly connected to the side wall of the operating table 1; a motor 19 is fixedly connected to the end of the first electric push rod 18; a chuck 110 is fixedly connected to the output end of the motor 19; a plurality of telescopic chucks 111 are slidably connected to the side wall of the chuck 110; a cleaning assembly is arranged on the top of the operating table 1; during operation, when cleaning the oxide scale on the surface of the roll, the roll is placed on the top of the first roller 16 and then one end is sleeved on the telescopic chuck 111. The two first rollers 16 cooperate with the second roller 17 below to fix the position of the roll. At this time, the hydraulic cylinder 12 is started to move up and down, which can drive the connecting plate 13 to move up and down. When the connecting plate 13 moves upward, the third roller 112 can rotate on its surface, and at this time, the distance between the two first rollers 16 can be made smaller. When the hydraulic cylinder 12 drives the connecting plate 13 to move downward, the distance between the two first rollers 16 can be made larger, so as to fix rolls with different diameters. Then the motor 19 is started to drive the roll to rotate, and at the same time, the cleaning assembly is started to clean the oxide scale on the surface of the roll. This step is to set the hydraulic cylinder 12 to connect the connecting plate 13, cooperate with the bracket 15, the first roller 16 and the second roller 17, and by changing the distance between the first rollers 16 and the height of the second roller 17, it is convenient to fix rolls with different diameters, so as to reduce the cumbersome operation caused by frequently replacing the corresponding clamping tools when fixing the roll.
[0025] As Figure 3 shown, the cleaning assembly includes a fixing frame 2; the fixing frame 2 is fixedly connected to the top of the operating table 1; a second electric push rod 21 is fixedly connected to the bottom of the fixing frame 2; a scraper 22 is fixedly connected to the end of the second electric push rod 21; during operation, when cleaning the oxide scale on the surface of the roll, the second electric push rod 21 is started to drive the scraper 22 to move towards the roll below. When the scraper 22 contacts the roll, under the continuous rotation of the roll, the surface of the roll can be scraped to scrape off the oxide scale. This step is to set the second electric push rod 21 to connect the scraper 22 to scrape off the oxide scale on the surface of the roll. At the same time, when the distance that the second electric push rod 21 drives the scraper 22 to move is different, it can adapt to rolls with different diameters to improve the applicability.
[0026] As Figure 3As shown, a pair of sliding grooves 3 are formed in the side wall of the fixing frame 2; a third electric push rod 31 is fixedly connected to the bottom of the inner side wall of the sliding groove 3; a slider 32 is fixedly connected to the end of the third electric push rod 31; a spring telescopic rod 33 is fixedly connected to the side wall of the slider 32; a roller 34 is fixedly connected to the end of the spring telescopic rod 33; during operation, when the rolling mill roll is fixed between the first roller 16 and the second roller 17, starting the third electric push rod 31 to drive the slider 32 to move can drive the spring telescopic rod 33 and the roller 34 to move, so that the roller 34 can contact the horizontal two sides of the rolling mill roll. When the sizes of the rolling mill rolls are different, the spring telescopic rod 33 will be stretched or contracted to different degrees to make the roller 34 fit tightly with the surface of the rolling mill roll. When the rolling mill roll rotates, the roller 34 will rotate simultaneously with the rolling mill roll. This step is to clamp and fix the rolling mill roll from the horizontal two sides by setting the third electric push rod 31 to connect the slider 32, the spring telescopic rod 33 and the roller 34, so as to improve the stability of the position of the rolling mill roll during rotation. At the same time, the third electric push rod 31 drives the spring telescopic rod 33 and the roller 34 to move and cooperate with the contraction or rebound of the spring telescopic rod 33, so as to adapt to rolling mill rolls of different diameters and improve the applicability.
[0027] As Figure 3 shown, an air pump 4 is fixedly connected to the top of the fixing frame 2; an air outlet pipe 41 is communicated with the side wall of the air pump 4; the air outlet pipe 41 is arranged close to the side wall of the scraper 22; during operation, when the second electric push rod 21 drives the scraper 22 to move towards the surface of the rolling mill roll, it will simultaneously drive the air outlet pipe 41 close to the surface of the rolling mill roll, and then start the air pump 4 to drive the air flow into the air outlet pipe 41 and then spray it onto the surface of the rolling mill roll, so as to blow off the scale scraped off from the surface of the rolling mill roll. This step is to blow air on the rolling mill roll by setting the air pump 4 to connect the air outlet pipe 41, so as to blow off the scraped scale, reduce the re-adhesion of the scale on the surface of the rolling mill roll after being scraped off, and improve the cleaning effect.
[0028] As Figure 4 shown, a collecting groove 5 is formed in the middle of the operating table 1; a water outlet pipe 51 is fixedly connected to the inner side wall of the collecting groove 5; a water inlet pipe 52 is communicated with the middle of the water outlet pipe 51; a liquid outlet groove 53 is formed in the side wall of the operating table 1 far away from the water outlet pipe 51; during operation, the scale scraped off and blown off will fall downward into the collecting groove 5 and be collected. Then, when an external water source is connected to the water inlet pipe 52, the water flow will flow into the collecting groove 5 from the water outlet pipe 51. At this time, the collecting groove 5 can be flushed to wash the fallen scale towards the liquid outlet groove 53 and then flow out of the collecting groove 5 from the liquid outlet groove 53. This step is to collect and wash off the cleaned scale by setting the collecting groove 5 in cooperation with the water inlet pipe 52, the water outlet pipe 51 and the liquid outlet groove 53, so as to reduce the situation that the scale accumulates on the top of the operating table 1 after falling off and causes secondary pollution to the rolling mill roll.
[0029] As Figure 4As shown, a collection box 6 is fixedly connected to the side wall of the operating table 1; a drain pipe 61 is communicated with the side wall of the collection box 6; the collection box 6 is arranged on one side close to the liquid outlet groove 53; during operation, when the water flow flushes the scale in the collection tank 5 out of the liquid outlet groove 53, it will flow into the collection box 6. At this time, the collection box 6 can collect the sewage that enters. After the collection is completed, the drain pipe 61 can be connected to discharge the sewage to the treatment location or the treatment container. By setting the collection box 6 to be connected to the drain pipe 61, the flushed sewage can be collected to reduce the pollution caused by the sewage discharged from the liquid outlet groove 53.
[0030] As Figure 4 shown, a filter screen 7 is detachably installed on the inner side wall of the collection box 6; during operation, when the sewage enters the collection box 6, it will be filtered by the filter screen 7. By setting the filter screen 7, the flushed water can be filtered, and some scale impurities mixed in the sewage can be filtered out, reducing the situation of blockage caused by the accumulation of impurities at the bottom of the collection box 6.
[0031] Working principle: When cleaning the scale on the surface of the rolling mill roll, place the roll on the top of the first roller 16 and then put one end on the telescopic clamping block 111. The two first rollers 16 on both sides cooperate with the second roller 17 below to fix the position of the roll. At this time, start the hydraulic cylinder 12 to move up and down, which can drive the connecting plate 13 to move up and down. When the connecting plate 13 moves upward, the third roller 112 can rotate on its surface. At this time, the distance between the two first rollers 16 on both sides can be reduced. When the hydraulic cylinder 12 drives the connecting plate 13 to move downward, the distance between the two first rollers 16 on both sides can be increased, so as to fix rolls with different diameters. Then start the motor 19 to drive the roll to rotate, and at the same time start the cleaning component to clean the scale on the surface of the roll. When cleaning the scale on the surface of the roll, start the second electric push rod 21 to drive the scraper 22 to move towards the roll below. When the scraper 22 contacts the roll and the roll rotates continuously, the surface of the roll can be scraped to scrape off the scale. When the roll is fixed between the first roller 16 and the second roller 17, start the third electric push rod 31 to drive the slider 32 to move, which can drive the spring telescopic rod 33 and the rotating roller 34 to move, so that the rotating roller 34 contacts the horizontal sides of the roll. When the size of the roll is different, the spring telescopic rod 33 will be stretched or contracted to different degrees, so that the rotating roller 34 fits tightly with the surface of the roll. When the roll rotates, the rotating roller 34 will rotate simultaneously with the roll. When the second electric push rod 21 drives the scraper 22 to move towards the surface of the roll, it will simultaneously drive the air outlet pipe 41 close to the surface of the roll. Then start the air pump 4 to drive the air flow into the air outlet pipe 41 and then spray it onto the surface of the roll, so as to blow off the scraped scale from the surface of the roll. After being scraped off and blown off, the scale will fall downward into the collection tank 5 and be collected. Then, when connecting the external water source to the water inlet pipe 52, the water flow will flow from the water outlet pipe 51 into the collection tank 5. At this time, the collection tank 5 can be flushed to wash the fallen scale towards the liquid outlet tank 53 and then flow out of the collection tank 5 from the liquid outlet tank 53. When the water flow flushes the scale in the collection tank 5 out of the liquid outlet tank 53, it will flow into the collection box 6. At this time, the collection box 6 can collect the sewage entering. When the collection is completed, the drain pipe 61 can be connected to drain the sewage to the treatment location or treatment container. When the sewage enters the collection box 6, it will be filtered by the filter screen 7.
