Description

Technical Field

[0001] The utility model relates to the technical field of water drainage on the surface of steel plates, and more specifically, to a water drainage device for the surface of medium and heavy steel plates. Background Art

[0002] A type of steel plate with a thickness of 4.5 mm to 25 mm commonly used in engineering is called medium and heavy plate; in a hot rolling medium and heavy plate mill, a large amount of scale is generated during the heating process of the steel billet in the heating furnace, and primary descaling is completed by the descaling box. Secondary scale is also generated during the rolling process. Therefore, during the rolling process, the on-machine descaling device completes the descaling of the secondary scale. However, after the descaling water of the on-machine descaling device hits the surface of the steel plate, it will accumulate on the surface of the steel plate. On the one hand, this accumulated water will cause the steel plate surface to oxidize again to generate scale, and on the other hand, due to the water accumulation on the plate surface, it will cause errors in the thickness measurement of the steel plate by the thickness gauge, resulting in a series of subsequent problems, such as the surface quality problem of the steel plate caused by the re-oxidation of the steel plate surface and the problem of unqualified steel plate thickness caused by the measurement thickness error. Once these problems occur, it is necessary to reorganize the rolling of the steel billet again, which not only affects the delivery date, reduces the production efficiency, but also increases the production cost for the re-rolling. Therefore, a water drainage device is proposed to clean the accumulated water on the surface of the steel plate.

[0003] After retrieval, for example, a Chinese patent application with the application number CN201220573353.7 discloses a water drainage device for the surface of medium and heavy steel plates. It uses high-pressure water, which is sprayed onto the surface of the steel plate through a water drainage header pipe and high-pressure nozzles installed on the rolling mill guard, to remove the accumulated water generated by the on-machine descaling on the surface of the steel plate, avoiding the surface quality problems of the steel plate and the measurement errors of the thickness gauge caused by water accumulation on the plate surface, ensuring the product quality, improving the production efficiency, and reducing the production cost.

[0004] However, when the above technical solution is used, since the nozzles and the water drainage header pipe are fixedly installed on the rolling mill guard, it can only drain water for steel plates with fixed dimensions, and the applicable range is limited. When draining water for steel plates with different thicknesses, it will affect the quality of the steel plate due to too high or too low water pressure. Summary of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a water drainage device for the surface of medium and heavy steel plates. The technical problem to be solved is that it can only drain water for steel plates with fixed dimensions, and the applicable range is limited.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A water drainage device for the surface of medium and heavy steel plates includes two brackets installed on the ground: A transmission mechanism is movably arranged between the two brackets, a flexible water pipe is fixedly arranged at the upper end of the transmission mechanism, and a steel plate is movably arranged at the upper end of the transmission mechanism.

[0007] An altitude adjustment device capable of adjusting the water spraying altitude is provided inside the bracket, which is used to adjust the water spraying altitude according to the requirements of the steel plate.

[0008] The altitude adjustment device includes a synchronous motor, which is fixedly arranged at the upper end of the bracket through a flange. The output end of the synchronous motor penetrates through the upper end of the bracket, and a rotating shaft is fixedly arranged at the output end of the synchronous motor.

[0009] An angle adjustment device capable of adjusting the water spraying angle is provided on one side of the altitude adjustment device, which is used to manually adjust the water spraying angle according to the requirements of the steel plate.

[0010] In a preferred embodiment, a limiting plate is fixedly arranged inside the bracket. The rotating shaft penetrates through the inside of the limiting plate, and the outer surface of the rotating shaft is movably connected with the inside of the limiting plate. A threaded shaft is fixedly arranged at the lower end of the rotating shaft.

[0011] In a preferred embodiment, a connecting plate is fixedly arranged inside the bracket. The lower end of the threaded shaft penetrates through the inside of the connecting plate, and the outer surface of the threaded shaft is movably connected with the inside of the connecting plate. A limiting slide bar is fixedly arranged between the limiting plate and the connecting plate.

[0012] In a preferred embodiment, a moving plate is movably arranged on the outer surface of the limiting slide bar. A threaded sleeve penetrates through the inside of the moving plate, and the inside of the threaded sleeve is in threaded connection with the outer surface of the threaded shaft.

[0013] In a preferred embodiment, the angle adjustment device includes an adjustment groove, which is opened on one side of the limiting slide bar. An adjustment sleeve is fixedly arranged inside the adjustment groove, and a water cutting header pipe is movably arranged inside the adjustment sleeve.

[0014] In a preferred embodiment, a toggle handle is fixedly arranged at the upper end of one side of the adjustment sleeve, and a scale plate is fixedly arranged at the upper end of the limiting slide bar. The toggle handle is located on one side of the scale plate.

[0017] 1.

The rotating shaft and the threaded shaft are driven to rotate synchronously by two motors with the same frequency. Due to the threaded connection between the threaded sleeve and the threaded shaft, the movable plate moves up and down, so the high-pressure nozzle can be adjusted in height. When the transmission mechanism transmits the steel plate, the height of the high-pressure nozzle is adjusted according to the water cutting needs of the steel plate, and the whole is suitable for water cutting work on steel plates of different thicknesses;

[0018] 2. The utility model is provided with an angle adjustment device, which is conducive to manually adjusting the water spray angle according to the needs of the steel plate.

DETAILED DESCRIPTION

[0024] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field of steel plate surface water cutting without making any creative efforts shall fall within the scope of protection of the present invention.

[0025] likeFigure 1 and 2 As shown in 2 , the utility model provides a water-shedding device for the surface of medium-thick steel plates, which includes two brackets 1 installed on the ground. A transmission mechanism 4 is movably arranged between the two brackets 1. A flexible water pipe 8 is fixedly arranged at the upper end of the transmission mechanism 4. A steel plate 5 is movably arranged at the upper end of the transmission mechanism 4. A plurality of high-pressure nozzles 6 are fixedly arranged on the outer surface of the water-shedding header 33. A connecting water pipe 7 is communicated with the upper end of the water-shedding header 33. A solenoid valve 9 is fixedly arranged on the outer surface of the connecting water pipe 7. A flexible water pipe 8 is fixedly arranged at the upper end of the connecting water pipe 7.

[0026] In order to be applicable to the water-shedding work on the surfaces of steel plates with different thicknesses, a height-adjusting device 2 capable of adjusting the spraying height is arranged inside the bracket 1 for adjusting the spraying height according to the requirements of the steel plate.

[0027] As Figure 3 shown, the height-adjusting device 2 includes a synchronous motor 21. The synchronous motor 21 is fixedly arranged at the upper end of the bracket 1 through a flange. The output end of the synchronous motor 21 penetrates through the upper end of the bracket 1. A rotating shaft 22 is fixedly arranged at the output end of the synchronous motor 21. A limiting plate 23 is fixedly arranged inside the bracket 1. The rotating shaft 22 penetrates through the inside of the limiting plate 23. The outer surface of the rotating shaft 22 is movably connected with the inside of the limiting plate 23. A threaded shaft 27 is fixedly arranged at the lower end of the rotating shaft 22. A connecting plate 24 is fixedly arranged inside the bracket 1. The lower end of the threaded shaft 27 penetrates through the inside of the connecting plate 24. The outer surface of the threaded shaft 27 is movably connected with the inside of the connecting plate 24. A limiting slide bar 26 is fixedly arranged between the limiting plate 23 and the connecting plate 24. A moving plate 25 is movably arranged on the outer surface of the limiting slide bar 26. A threaded sleeve 28 penetrates through the inside of the moving plate 25. The inside of the threaded sleeve 28 is threadedly connected with the outer surface of the threaded shaft 27. By driving the rotating shaft 22 and the threaded shaft 27 to rotate synchronously by two synchronous motors 21, due to the threaded connection between the threaded sleeve 28 and the threaded shaft 27, the moving plate 25 moves up and down. Therefore, the high-pressure nozzle 6 can adjust its height. When the transmission mechanism transports the steel plate 5, according to the water-shedding requirements of the steel plate 5, the height of the high-pressure nozzle 6 is adjusted, so that the utility model can be applicable to the water-shedding work on steel plates 5 with different thicknesses.

[0028] Furthermore, in order to be able to adjust the spraying angle, an angle-adjusting device 3 capable of adjusting the spraying angle is arranged on one side of the height-adjusting device 2 for manually adjusting the spraying angle according to the requirements of the steel plate.

[0029] As Figure 4As shown in the figure, the angle adjustment device 3 includes an adjustment groove 31, which is opened on one side of the limit slide bar 26. An adjustment sleeve 32 is fixedly arranged inside the adjustment groove 31. A water-cutting collector pipe 33 is movably arranged inside the adjustment sleeve 32. A toggle handle 34 is fixedly arranged at the upper end of one side of the adjustment sleeve 32. A scale plate 35 is fixedly arranged at the upper end of the limit slide bar 26. The toggle handle 34 is located on one side of the scale plate 35. A plurality of high-pressure nozzles 6 are fixedly arranged on the outer surface of the water-cutting collector pipe 33. A connecting water pipe 7 is communicated with the upper end of the water-cutting collector pipe 33. A solenoid valve 9 is fixedly arranged on the outer surface of the connecting water pipe 7. A flexible water pipe 8 is fixedly arranged at the upper end of the connecting water pipe 7. By fixedly arranging the adjustment sleeve 32 inside the adjustment groove 31, the water-cutting collector pipe 33 is limited to rotate inside the two adjustment sleeves 32. When the water-cutting angle needs to be adjusted, the water-cutting collector pipe 33 is driven to rotate by rotating the toggle handle 34. Therefore, the water spraying direction of the high-pressure nozzles 6 fixedly arranged on the outer surface of the water-cutting collector pipe 33 realizes the adjustment effect. The water spraying angle of the high-pressure nozzles 6 can be determined according to the alignment scale between the toggle handle 34 and the scale plate 35 observed.

[0030] The working principle is as follows: When the present utility model is in use, the steel plate 5 is conveyed to the transmission mechanism 4 for transmission by a rolling mill. The height of the high-pressure nozzles 6 is adjusted by the height adjustment device 2, and then the angle adjustment device 3 is manually controlled to adjust the water spraying angle of the high-pressure nozzles 6. After the adjustment is completed, the two flexible water pipes 8 inject water into the two connecting water pipes 7, so as to flow into the high-pressure nozzles 6 from the water-cutting collector pipe 33, and then the water is sprayed on the surface of the steel plate 5 to cut the dephosphorization water and accumulated water on the steel plate 5.

[0031] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
