Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and more specifically, to a slab cleaning device. Background Technology

[0002] The presence of iron oxide scale and surface inclusions on the slab surface can lead to misjudgment or missed detection of defects. Therefore, it is necessary to clean the slab surface first in order to better discover and deal with the existing defects.

[0003] Currently, steel plants typically use offline manual cleaning technology to remove surface iron oxide scale (commonly known as "cold descaling") or inclusions from slabs in a cold state. This involves manually blowing the surface with a heavy-duty cutting torch. However, because manual cleaning relies heavily on the experience of the personnel, uneven cleaning and inconsistent cleaning depth can occur. This unevenness and instability in manual blowing can lead to significant blow-off, necessitating secondary cleaning to ensure accurate defect identification in subsequent slab processing, thus increasing the processing time. Utility Model Content

[0004] The problem this invention addresses is how to improve the efficiency of slab cleaning.

[0005] To solve the above problems, this utility model provides a slab cleaning device.

[0006] In a first aspect, this utility model provides a slab cleaning device, including a moving mechanism, a fixed bracket, and a roller brush mechanism. The fixed bracket is mounted on the moving mechanism, and the roller brush mechanism is mounted on the fixed bracket. The moving mechanism is used to drive the roller brush mechanism to clean the surface of the slab through the fixed bracket.

[0007] The roller brush mechanism includes a roller brush, a drive shaft, connecting plates, swing plates, a suspension bolt, a positioning tie rod, a nut, a spring, and a drive mechanism. Two connecting plates are spaced apart and connected to the fixed bracket. Both ends of the drive shaft are connected to the two connecting plates respectively. Two swing plates are connected to both ends of the roller brush. The roller brush is rotatably connected to the drive shaft via the two swing plates. Both ends of the positioning tie rod are connected to the two swing plates respectively. One end of the suspension bolt passes through the fixed bracket, and the end of the suspension bolt away from the fixed bracket is connected to the positioning tie rod. The nut is located at the end of the suspension bolt near the fixed bracket and is used to contact the end face of the fixed bracket opposite to the positioning tie rod. One end of the spring is connected to the positioning tie rod, and the other end is connected to the end face of the fixed bracket facing the positioning tie rod. The drive mechanism is used to drive the roller brush to rotate.

[0008] Optionally, two roller brushes are provided, which are symmetrically arranged on both sides of the drive shaft and rotatably connected to the drive shaft through two swing plates respectively.

[0009] Optionally, the drive mechanism includes a first motor, a single sprocket, and a triple sprocket. The first motor is mounted on the connecting plate, the triple sprocket is connected to one end of the drive shaft, the first motor is drively connected to the triple sprocket, the two single sprockets are respectively connected to the two roller brushes, and the triple sprocket is connected to the two single sprockets by chains.

[0010] Optionally, the roller brush mechanism further includes a fixed pull ring, which is disposed on the positioning pull rod, and the rod bolt and the spring are respectively connected to the fixed pull ring.

[0011] Optionally, the roller brush mechanism further includes a bearing, the inner ring of which is connected to the drive shaft, and the end of the swing plate away from the roller brush is connected to the outer ring of the bearing.

[0012] Optionally, the moving mechanism includes a lateral moving mechanism, which includes a rail frame, a screw, a threaded block, and a second motor. The screw is rotatably connected to the rail frame, the threaded block is disposed on the fixed bracket and threadedly connected to the screw, and the second motor is disposed on the rail frame and is drivenly connected to the screw.

[0013] Optionally, the lateral movement mechanism further includes a support rod and pulleys, with pulleys provided at both ends of the support rod. The support rod is connected to the rail frame via two pulleys and is connected to a fixed bracket.

[0014] Optionally, the moving mechanism further includes a moving vehicle, and the lateral moving mechanism is mounted on the moving vehicle, which is used to drive the lateral moving mechanism to move.

[0015] Optionally, the bearing is a copper bushing.

[0016] Optionally, the roller brush is a steel wire roller brush.

[0017] The beneficial effects of this slab cleaning device are as follows: a fixed bracket is installed on the moving mechanism, and the roller brush mechanism is installed on the fixed bracket. The fixed bracket fixes the roller brush mechanism, and the moving mechanism drives the roller brush mechanism to move through the fixed bracket. The roller brush mechanism rotates under the drive of the driving mechanism to clean the slab surface. A connecting plate fixes the transmission shaft to the fixed frame. The roller brush is rotatably connected to the transmission shaft through two swing plates. A positioning tie rod connects the two swing plates to prevent the roller brush from deforming due to different swing angles of the two swing plates. A hanging rod bolt is set vertically on the fixed bracket, and its two ends are connected to the positioning tie rod and the fixed bracket respectively. The end with the nut overlaps with the fixed bracket to facilitate adjustment of the initial height of the positioning tie rod. A spring is set between the positioning tie rod and the fixed bracket. When the slab deforms, for example, by tilting upwards, the roller brush and the swing plates swing upwards with the upward deformation of the slab, increasing the distance between the nut and the fixed bracket, and compressing the spring. When the slab returns to its basic position, the spring assists the roller brush in resetting. The driving mechanism is used to drive the roller brush to rotate to clean the slab. In use, the suspension height of the swing plate can be adjusted by adjusting the position of the nut on the hanger bolt according to the deformation of the slab, thereby adjusting the distance between the roller brush and the slab surface. The moving mechanism operates, driving the roller brush mechanism to move via the fixed bracket. The drive mechanism drives the roller brush to rotate. Due to the slight deformation of the slab, which causes it to sag or bulge upwards, the roller brush floats on the slab surface by its own weight. The roller brush uses its own weight and the downward force applied by the spring to clean the slab surface. This prevents the roller brush from leaving the slab surface or getting stuck due to slab deformation, ensuring stable and smooth operation, effectively reducing the accident rate, guaranteeing the uniformity and stability of slab surface cleaning, and improving slab cleaning efficiency. Furthermore, since this embodiment utilizes the moving mechanism and drive structure to achieve automated cleaning, it can improve cleaning uniformity and avoid the need for secondary manual cleaning, further improving cleaning efficiency.

[0033] like Figures 1 to 6 As shown, in view of the problems existing in the above-mentioned related technologies, this embodiment provides a slab cleaning device, including a moving mechanism, a fixed bracket 2 and a roller brush mechanism 3. The fixed bracket 2 is installed on the moving mechanism, and the roller brush mechanism 3 is installed on the fixed bracket 2. The moving mechanism is used to drive the roller brush mechanism 3 to clean the slab surface through the fixed bracket 2. That is, the moving mechanism drives the roller brush mechanism 3 to move to the position to be cleaned by moving the fixed bracket 2, so as to clean the slab surface.

[0034] The roller brush mechanism 3 includes a roller brush 31, a drive shaft 32, a connecting plate 33, a swing plate 34, a hanging rod bolt 35, a positioning tie rod 36, a nut 37, a spring 38, and a drive mechanism 39. Two connecting plates 33 are spaced apart and connected to the fixed bracket 2. The drive shaft 32 is connected between the two connecting plates 33 to fix the drive shaft 32 and prevent it from shaking during cleaning, thus affecting the cleaning effect. Two swing plates 34 are respectively connected to both ends of the roller brush 31. The roller brush 31 is connected to the drive shaft 32 through the two swing plates 34. The positioning tie rod 36 is horizontally connected between the two swing plates 34 to prevent deformation of the roller brush 31 caused by uneven swing angles of the two swing plates 34. The suspension bolt 35 is vertically mounted on the fixed bracket 2. The end of the suspension bolt 35 away from the fixed bracket 2 is connected to the positioning tie rod 36. The nut 37 is located at the end of the suspension bolt 35 near the fixed bracket 2. The nut 37 contacts the end face of the fixed bracket 2 opposite to the positioning tie rod 36. The suspension bolt 35 is suspended by a swing plate 34 to adjust the distance between the roller brush 31 and the slab surface. By adjusting the nut 37 and moving it along the suspension bolt 35, the suspension height of the swing plate 34 can be adjusted to adjust the distance between the roller brush 31 and the slab surface. For example, as... Figure 3 As shown, region A is a cross-sectional structure of the suspension bolt 35, nut 37, and spring 38. In the initial state, two nuts 37 are installed at the top of the suspension bolt 35 to suspend and adjust the position of the roller brush 31 relative to the theoretically flat slab surface. It should be noted that during the initial adjustment of the roller brush 31 position, the distance h between the lower end face of the end of the swing plate 34 connected to the drive shaft 32 and the theoretically flat slab surface is greater than or equal to the radius of the roller brush 31, so that the roller brush 31 has a certain space for upward movement to accommodate slab deformation. One end of the spring 38 is connected to the positioning rod 36, and the other end is connected to the end face of the fixed bracket 2 facing the positioning rod 36. After the initial adjustment of the position of the roller brush 31, the distance between the connection point of the spring 38 and the positioning rod 36 and the fixed bracket 2 is less than the static length of the spring 38, that is, the spring 38 is compressed to apply a downward force to the roller brush 31, so that the roller brush 31 is always in contact with the surface of the slab during movement. At the same time, when the roller brush 31 moves upward as the slab surface deforms and lifts, it assists the roller brush 31 to fall back. The driving mechanism 39 is used to drive the roller brush 31 to rotate.

[0035] Specifically, the distance h between the lower end face of the end of the swing plate 34 connected to the drive shaft 32 and the theoretically flat slab surface is obtained through a large amount of slab deformation data. For example, if the slab deformation data is usually within 0-100mm, then h is set to be greater than or equal to 100mm to ensure that the drive shaft 32 will not collide with the slab when cleaning it. The theoretically flat slab surface refers to the surface of the flat portion of the slab. The distance between the roller brush 31 and the theoretically flat slab surface is also obtained through a large amount of slab deformation data. For example, if the slab deformation data is usually within 0-100mm, then the distance range is 0-100mm. The suspension height of the swing plate 34 can be adjusted between 0-100mm, and the suspension height of the swing plate 34 can be adjusted in real time according to the actual situation by adjusting the target position of the nut 37 along the suspension bolt 35, which is more conducive to on-site use and maintenance. The size of the roller brush 31 also needs to be selected according to the slab deformation data, and the radius of the roller brush 31 needs to be greater than the slab deformation. For example, if the slab deformation is 100mm, then the radius of the roller brush 31 should be greater than 100mm. In this embodiment, a roller brush 31 with a diameter of 240-250mm is selected, which is suitable for cleaning most slabs.

[0036] During slab cleaning, the slab is fixed by the slab support 4, and cleaning is performed on one side only. After cleaning one side, the slab needs to be flipped over to clean the other side. Furthermore, the slab cleaning device of this embodiment can well adapt to situations such as downward or upward tilting of the slab ends, and can meet the requirement of uniform cleaning of the entire slab surface when the slab ends are tilted downward or upward. For example... Figure 5 As shown, the slab is supported and fixed by the support base 4. The starting or ending end of the slab deflects downwards, and the height difference between the surface of the deflected end and the theoretically flat slab surface is E≦30mm. The suspension bolt 35 suspends the roller brush 31, and the adjusting nut 37 limits the lower movement plane of the roller brush 31 to 30mm below the theoretically flat slab surface dimension, so that the lower movement plane of the roller brush 31 contacts the surface of the deflected end of the slab, thus satisfying the requirement that the deflected end is also within the cleaning range. Figure 6As shown, the slab is supported and fixed by the support base 4. The starting end or the end of the slab is curved upwards, and the height difference between the surface of the curved end and the theoretically flat slab surface is S≦70mm. The roller brush 31 is suspended by the hanging bolt 35. The lower moving plane of the roller brush 31 is limited to be level with the theoretically flat slab surface by the adjusting nut 37. When the roller brush 31 moves from the curved end of the slab to the upper surface of the slab, the lower moving plane of the roller brush 31 is 70mm lower than the surface of the curved end of the slab. Since S < the radius of the roller brush 31, the impact point of the roller brush 31 contacting the curved end of the slab is below the horizontal reference plane of the center of the roller brush 31, and the rotation direction of the roller brush 31 is the same as the running direction. In this way, when the roller brush 31 moves to the curved end of the slab, the rotation of the roller brush 31 will lift the roller brush 31 directly onto the upper surface of the slab. Then, based on the downward force applied by the spring 38 and the weight of the roller brush 31, the lower moving surface of the roller brush 31 is always in contact with the upper surface of the slab. At this time, the hanger bolt 35 can move freely in the hole of the hanger beam without dead points, and since h>S, the swing plate 34 will not scrape or collide with the surface of the slab.

[0037] In this embodiment, the fixed bracket 2 is installed on the moving mechanism, and the roller brush mechanism 3 is installed on the fixed bracket 2. The fixed bracket 2 fixes the roller brush mechanism 3. The moving mechanism drives the roller brush mechanism 3 to move through the fixed bracket 2. The roller brush mechanism 3 rotates under the drive of the driving mechanism 39 to clean the surface of the slab. The connecting plate 33 fixes the drive shaft 32 to the fixed frame. The roller brush 31 is rotatably connected to the drive shaft 32 via two swing plates 34. The positioning rod 36 connects the two swing plates 34 to prevent the roller brush 31 from deforming due to different swing angles of the two swing plates 34. The hanger bolt 35 is set vertically on the fixed bracket 2, and its two ends are connected to the positioning rod 36 and the fixed bracket 2 respectively. The end with the nut 37 overlaps with the fixed bracket 2. The initial height of the positioning rod 36 and the swing plates 34 can be adjusted by the nut 37 and the hanger bolt 35. The spring 38 is set between the positioning rod 36 and the fixed bracket 2. When the slab deforms (e.g., warps upward), the roller brush 31 and the swing plates 34 swing upward with the warping deformation of the slab. The distance between the nut 37 and the fixed bracket 2 increases, and the spring 38 is compressed. When the slab returns to its basic position, the spring 38 assists the roller brush 31 to reset. The drive mechanism 39 is used to drive the roller brush 31 to rotate to clean the slab. In use, the suspension height of the swing plate 34 can be adjusted by adjusting the position of the nut 37 on the hanger bolt 35 according to the deformation of the slab, thereby adjusting the distance between the roller brush 31 and the slab surface. The moving mechanism operates, driving the roller brush mechanism 3 to move via the fixed bracket 2. The drive mechanism 39 drives the roller brush 31 to rotate. Due to the slight deformation of the slab, which causes it to sag downwards or bend upwards, the roller brush 31 floats on the slab surface by its own weight. The roller brush 31 cleans the slab surface using its own weight and the downward force applied by the spring 38. This prevents the roller brush 31 from leaving the slab surface or getting stuck due to slab deformation, ensuring stable and smooth operation, effectively reducing the accident rate, guaranteeing the uniformity and stability of slab surface cleaning, and improving slab cleaning efficiency. Furthermore, since this embodiment utilizes the moving mechanism and drive structure 38 to achieve automated cleaning, it can improve cleaning uniformity, avoid the need for secondary manual cleaning, and further improve cleaning efficiency.

[0038] Optionally, such as Figure 3 As shown, there are two roller brushes 31, which are symmetrically arranged on both sides of the drive shaft 32 and are rotatably connected to the drive shaft 32 through two swing plates 34 respectively.

[0039] Specifically, in order to increase cleaning efficiency, two roller brushes 31 are usually provided and symmetrically arranged on both sides of the drive shaft 32. Correspondingly, two pairs of swing plates 34 are provided, and two springs 38 and two hanging rod bolts 35 are provided.

[0040] Optionally, such as Figure 2 As shown, the drive mechanism 39 includes a first motor 391, a single sprocket 392, and a triple sprocket 393. The first motor 391 is mounted on the connecting plate 33 and is connected to the drive shaft 32. The triple sprocket 393 is connected to one end of the drive shaft 32. The two single sprockets 392 are respectively connected to the two roller brushes 31. The triple sprocket 393 is connected to the two single sprockets 392 by chains.

[0041] Specifically, the first motor 391 is mounted on the connecting plate 33, and a triple sprocket 393 is mounted on one end of the transmission shaft 32. The first motor 391 and the triple sprocket 393 are connected by a chain drive. Two single sprockets 392 are respectively mounted on one end of the roller brush 31. It should be noted that the triple sprocket 393 and the two single sprockets 392 are all mounted on the same end of the roller brush 31 for easy connection. The triple sprocket 393 is connected to the two single sprockets 392 by a chain. When the first motor 391 drives the triple sprocket 393 to rotate, the triple sprocket 393 drives the two single sprockets 392 to rotate through the chain, thereby driving the two roller brushes 31 to rotate.

[0042] It should be noted that the triple sprocket 393 can be rotatably connected to the drive shaft 32 or fixedly connected to the drive shaft 32. When the triple sprocket 393 is rotatably connected to the drive shaft 32, the first motor 391 drives the triple sprocket 393 to rotate, and the drive shaft 32 does not rotate. When the triple sprocket 393 is fixedly connected to the drive shaft 32, the first motor 391 drives the triple sprocket 393 to rotate, and the drive shaft 32 rotates, but the swing plate 34 does not rotate with the drive shaft 32. This can be achieved by setting a bearing to connect the drive shaft 32 and the swing plate 34, ensuring that the swing plate 34 does not rotate with the drive shaft 32 during its rotation.

[0043] Optionally, such as Figure 3 As shown, the roller brush mechanism 3 also includes a fixed pull ring 30, which is disposed on the positioning pull rod 36. The hanging rod bolt 35 and the spring 38 are respectively connected to the fixed pull ring 30 to stably connect the spring 38 and the hanging rod bolt 35 to the positioning rod.

[0044] Optionally, such as Figure 2 As shown, the roller brush mechanism 3 also includes a bearing 300, the inner ring of which is connected to the drive shaft 32, and the end of the swing plate 34 away from the roller brush 31 is connected to the outer ring of the bearing 300 to ensure that the swing plate 34 does not rotate with the rotation of the drive shaft 32.

[0045] Optionally, the bearing 300 may be a copper bushing.

[0046] Optionally, such as Figure 4As shown, the moving mechanism includes a lateral moving mechanism 1, which includes a rail frame 11, a screw 12, a threaded block 13, and a second motor 14. The screw 12 is rotatably connected to the rail frame 11, the threaded block 13 is disposed on the fixed bracket 2 and threadedly connected to the screw 12, and the second motor 14 is disposed on the rail frame 11 and is drivenly connected to the screw 12.

[0047] Specifically, the rail frame 11 is a rectangular frame, the screw 12 is set along the length of the rail frame 11 and is rotatably connected to the rail frame 11, and the threaded block 13 is threadedly connected to the screw 12. The threaded block 13 and the screw 12 form a screw drive mechanism. The threaded block 13 is connected to the fixed bracket 2. When the second motor 14 drives the screw 12 to rotate around its own axis, the threaded block 13 moves relative to the screw 12 to produce horizontal displacement, and drives the roller brush mechanism 3 to move in the horizontal direction through the fixed bracket 2.

[0048] Optionally, such as Figure 4 and Figure 3 As shown, the lateral movement mechanism 1 also includes a support rod 15 and pulleys 16. The two ends of the support rod 15 are respectively provided with pulleys 16. The support rod 15 is connected to the rail frame 11 through the two pulleys 16. When the screw 12 rotates, the support rod 15 slides on the rail frame 11 through the pulleys 16. The support rod 15 is connected to the fixed bracket 2 so that the fixed bracket 2 drives the roller brush mechanism 3 to slide in the horizontal direction, thereby increasing the stability of movement.

[0049] Specifically, the fixed bracket 2 may include a U-shaped plate and a fixed plate. The bottom end of the U-shaped plate is connected to the fixed plate, the hanging rod bolt 35 is set on the fixed plate, and the top end of the U-shaped plate is connected to the support rod 15 to fix the support rod 15.

[0050] Optionally, the moving mechanism further includes a moving vehicle, and the lateral moving mechanism 1 is mounted on the moving vehicle, which is used to drive the lateral moving mechanism 1 to move.

[0051] Specifically, the mobile vehicle may include an overhead crane.

[0052] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
