[0068] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0069] Please see Figure 1 , Figure 2 and Figure 10 This application provides a steel pipe surface cleaning device, including a workbench 1, a housing 2, a rotating assembly 5, a reciprocating assembly 6, and a cleaning assembly 7.

[0070] In the specific implementation, the workbench 1 is set horizontally, and the four corners of the workbench 1 are fixedly installed with brackets 3 for supporting devices. The bottom of the four brackets 3 is fixedly installed with bases 4 for strengthening stable support.

[0071] The housing 2 is fixed parallel to the top surface of the workbench 1. The interior of the housing 2 is hollow, and its front and bottom surfaces are openwork.

[0072] The rotating component 5 passes through the side of the housing 2 and is arranged parallel to the inside of the housing 2, and can rotate relative to the housing 2 along the part through which the housing 2 is penetrated;

[0073] The reciprocating assembly 6 is arranged parallel to the outside of the rotating assembly 5 and can move relative to the rotating assembly 5 in the lateral direction. The reciprocating assembly 6 is provided with a clamping assembly 11 for clamping the steel pipe.

[0074] The cleaning component 7 is disposed between the rotating component 5 and the reciprocating component 6. The cleaning component 7 rotates relative to the rotating component 5 and can move laterally relative to the reciprocating component 6.

[0075] In practice, the workbench 1, housing 2, support 3, and base 4 all serve as load-bearing structures to support the entire cleaning device. The clamping assembly 11 is used to clamp the ends of the steel pipes that need to be cleaned, facilitating the cleaning process. The rotating assembly 5 acts as a drive assembly, driving the reciprocating assembly 6 and the cleaning assembly 7, ultimately completing the cleaning process on the steel pipes.

[0076] refer to Figure 3 Based on the above scheme, a specific implementation of the rotating component 5 is provided. The rotating component 5 includes: a motor 52, a connecting shaft 53, a pinion 54, and four large gears 55.

[0077] In specific implementation, the motor 52 is horizontally fixed to the right side of the housing 2 by bolts, and the motor base 51 is fixedly installed on the lower surface of the motor 52. The motor base 51 is fixedly installed on the side of the housing 2 and is used to enhance the installation stability of the motor 52.

[0078] One end of the connecting shaft 53 is fixedly installed at the output end of the motor 52, and the other end away from the motor 52 moves through the right side of the housing 2 and the reciprocating assembly 6 in sequence, and extends into the interior of the housing 2.

[0079] A small gear 54 is fixedly mounted on the outer wall of the left end of the connecting shaft 53, and four large gears 55 are meshed with it. A short shaft 56 is fixedly mounted on the inner wall of the large gear 55, and the left end of the short shaft 56 is rotatably connected to the inner surface of the housing 2 via a bearing. The side edge of the large gear 55 is connected to the cleaning assembly 7.

[0080] It is worth noting that here, the small gear 54 is individually meshed with the four large gears 55, and there is a gap between the four large gears 55 to prevent them from meshing together and getting stuck.

[0081] Specifically, the motor 52 acts as a drive, and when the motor 52 is started, the connecting shaft 53 can rotate. When the connecting shaft 53 rotates, the reciprocating component 6 can work, and at the same time, the small gear 54 drives the large gear 55 to rotate, thereby enabling the cleaning component 7 to work.

[0082] refer to Figure 4 , Figure 5 ,and Figure 6 Based on the above implementation scheme, this application provides a specific implementation of the reciprocating component 6, which includes a cover 61, an annular plate 62, a placement body 63, and an auxiliary disk 64.

[0083] In specific implementation, the cover 61 has an internal cavity, and its left side is hollow. It is arranged parallel to the housing 2 and located above the worktable 1. The cover 61 is movably fitted onto the outer wall of the connecting shaft 53, and mounting components are fixedly installed on the surface of the cover 61.

[0084] Specifically, the mounting components include an upper mounting block 8 fixedly mounted on the lower surface of the cover 61, and a lower mounting block 9 fixedly perpendicular to the top surface of the workbench 1. The upper mounting block 8 and the lower mounting block 9 are connected by bolts.

[0085] The annular plate 62 is slidably fitted into the inner annular groove 66 opened in the inner wall of the cover 61. The annular plate 62 can move relative to the cover 61 along the inner annular groove 66. One end of the placement body 63 is set inside the cover 61, and the outer wall of the right end of the placement body 63 is fixedly installed with the inner wall of the annular plate 62. The placement body 63 is movably fitted onto the outer wall of the connecting shaft 53.

[0086] In one specific embodiment, the right side of the placement body 63 is inclined, and the left side of the placement body 63 is provided with four annularly spaced placement grooves 10; the auxiliary disk 64 is disposed inside the cover 61 and is fixedly sleeved on the outer wall of the connecting shaft 53.

[0087] In one specific embodiment, the left side of the auxiliary disk 64 is inclined, and the auxiliary disk 64 is in contact with the right side of the placement body 63.

[0088] It is worth noting that there are two sets of mounting components here, with the other set located between the upper surface of the cover 61 and the top of the inner wall of the housing 2. Using two sets of mounting components allows the cover 61 to be stably installed, and the mounting components are connected by bolts to facilitate disassembly and maintenance later.

[0089] It is worth noting that the auxiliary disk 64 is fixedly sleeved on the outer wall of the connecting shaft 53. Therefore, the auxiliary disk 64 can rotate under the action of the connecting shaft 53. Since the surfaces of the auxiliary disk 64 and the placement body 63 that are in contact with each other are both inclined, and the annular plate 62 and the inner annular groove 66 are slidably arranged, the placement body 63 can move stably after the auxiliary disk 64 rotates.

[0090] As a specific implementation, the reciprocating assembly 6 also includes a pair of large springs 65 that are vertically fixed to the right side of the annular plate 62. The end of the large spring 65 away from the annular plate 62 is fixedly installed on the inner wall of the inner annular groove 66. The two large springs 65 are provided here to realize the lateral reciprocating movement of the placement body 63, and finally make the steel pipe held by the clamping assembly 11 reciprocate, increase the friction between it and the cleaning assembly 7, and strengthen the cleaning force.

[0091] refer to Figure 4 and Figure 9 Based on the above implementation scheme, this application provides a specific implementation of the clamping component 11, which includes an arc-shaped clamping plate 111 and an elastic body 112.

[0092] An arc-shaped clamping plate 111 is disposed in the placement groove 10, and the right end of the arc-shaped clamping plate 111 can move longitudinally along the inner wall of the placement groove 10; one end of the elastic body 112 is vertically fixed to the surface of the arc-shaped clamping plate 111, and the other end of the elastic body 112 is fixed to the inner wall of the placement groove 10.

[0093] In a preferred embodiment, the surface of the elastomer 112 has a corrugated pattern. Here, the elastomer 112 is made of a rubber material with low elasticity to prevent the clamped steel pipe from loosening due to excessive force and vibration. There are sixteen arc-shaped clamping plates 111, with four arc-shaped clamping plates 111 grouped together to clamp the steel pipe. The number and distribution of the elastomers 112 are consistent with the number and distribution of the arc-shaped clamping plates 111.

[0094] like Figure 3 , Figure 7 and Figure 8 As shown, based on the above implementation scheme, this application provides a specific implementation of the cleaning component 7, which includes a long arc plate 71 and a short arc plate 72.

[0095] In the specific implementation, the long arc-shaped plate 71 is vertically fixed to the side of the edge of the large gear 55; the short arc-shaped plate 72 directly contacts the left side of the placement body 63. The short arc-shaped plate 72 and the long arc-shaped plate 71 are connected by a connecting component, and an ultrasonic device (not shown in the figure) is installed between the short arc-shaped plate 72 and the long arc-shaped plate 71. A cleaning bristle (not shown in the figure) is fixedly installed on the concave surface of the short arc-shaped plate 72. The ultrasonic device can generate a micro-vibration effect, which can shake off impurities on the cleaning bristles on the short arc-shaped plate 72, making it easier for the cleaning bristles to effectively clean the surface of the steel pipe.

[0096] It is worth noting that there are four cleaning components 7, arranged in a ring with equal spacing. This solution... Figure 3 The distance between each pair of adjacent cleaning components 7 is designed for display purposes, but in actual design, it is designed to facilitate the placement and clamping of steel pipes.

[0097] Based on the above implementation scheme, this application provides a specific implementation of a connecting component, which includes a first connecting block 73 and a second connecting block 74.

[0098] Specifically, the first connecting block 73 is vertically fixedly installed on the concave surface of the long arc plate 71; the second connecting block 74 is vertically fixedly installed on the arc surface of the short arc plate 72.

[0099] In a specific embodiment, the first connecting block 73 and the second connecting block 74 are movably connected by a pin 75. A small spring 76 is sleeved on the outer wall of the pin 75. One end of the small spring 76 is fixedly connected to the front of the first connecting block 73, and the other end of the small spring 76 is fixedly connected to the back of the second connecting block 74. It is worth noting that here, the center of the large gear 55 is on the same horizontal plane as the centers of the long arc plate 71 and the short arc plate 72. The rotation of the large gear 55 can cause the long arc plate 71 to rotate. Since the long arc plate 71 and the short arc plate 72 are connected by a connecting component, the short arc plate 72 will rotate accordingly. Because the center of the large gear 55 is on the same horizontal plane as the centers of the long arc plate 71 and the short arc plate 72, the short arc plate 72 will rotate around the center of the steel pipe, realizing the cleaning bristles' 360° cleaning work on the steel pipe.

[0100] As can be seen from the above technical solution, the placement body 63 can move back and forth. Since the right end face of the short arc plate 72 is in contact with the left side of the placement body 63, and the first connecting block 73 and the second connecting block 74 are movably connected, the short arc plate 72 can move laterally, causing the cleaning bristles to move along with it, thus increasing the small cleaning range. With the cooperation of the small spring 76, the cleaning bristles can clean repeatedly, and at the same time, the cleaning bristles can vibrate slightly to shake off dirt and avoid affecting the cleaning of the cleaning bristles.

[0101] Working principle: After the steel pipe has been processed and heat-treated, the steel pipe that needs to be cleaned is placed in the placement groove 10, and the end of the steel pipe is clamped between the four arc-shaped clamping plates 111 in each group.

[0102] Once the steel pipe is clamped, the connecting shaft 53 rotates by starting the motor 52. This rotation of the connecting shaft 53 causes the auxiliary disk 64 and the pinion 54 to rotate. Due to the arrangement between the auxiliary disk 64 and the placement body 63, and through the annular plate 62 and the large spring 65, the placement body 63 can reciprocate as the auxiliary disk 64 rotates. This reciprocating movement of the placement body 63 allows the clamped steel pipe to move back and forth, increasing the friction between it and the cleaning bristles and enhancing the cleaning effect.

[0103] The rotation of the small gear 54 causes the large gear 55 to rotate, which in turn drives the long arc plate 71 to rotate. Due to the connecting components, the short arc plate 72 also rotates, achieving 360° cleaning of the steel pipe by the cleaning bristles. Combined with the reciprocating movement of the steel pipe, the cleaning range is increased, and the friction coefficient between the two is strengthened, thus increasing the cleaning power and effect.

[0104] The reciprocating movement of the placement body 63 causes the short arc-shaped plate 72 to reciprocate as well. Due to the small spring 76, this reciprocating movement of the short arc-shaped plate 72 allows the cleaning bristles mounted on its surface to repeatedly clean the steel pipe. This increases the cleaning range and intensity on the steel pipe surface, while the dust on the cleaning bristles vibrates slightly under the action of the small spring 76. Furthermore, with the assistance of an ultrasonic device, the dust on the cleaning bristles can be shaken off, and the 360° rotation also helps to fling away dust, ultimately preventing dust accumulation on the cleaning bristles and ensuring effective cleaning.
