Description

Technical Field

[0001] This utility model relates to the field of steel pipe surface treatment, and specifically to a steel pipe cleaning mechanism. Background Technology

[0002] After being stored for a period of time, steel pipes easily accumulate dust, dirt, and even rust on their inner and outer surfaces. While the inner surface of the steel pipe has less dust and rust than the outer surface, cleaning the outside of the steel pipe is relatively simple, while cleaning the inside is more difficult.

[0003] Currently, the most efficient cleaning method is to use a high-pressure water gun to rinse. This method is very effective at cleaning dust, but it is difficult to effectively deal with rust or dirt with strong adhesion.

[0004] Furthermore, when using a high-pressure water gun for rinsing, it is necessary to remove any residual moisture from the steel pipes after rinsing to prevent the dampness from causing oxidation and rust on the inner walls, which increases costs. Wastewater treatment after rinsing is also a problem. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a steel pipe cleaning mechanism to solve the technical problems of poor rust removal effect of high-pressure water gun washing on the inner wall of steel pipe and increased cost caused by water removal and sewage treatment in the prior art.

[0006] To achieve the above objectives, this utility model provides a steel pipe cleaning mechanism, including a drive motor for driving the entire mechanism to clean the inner surface of the steel pipe, and the cleaning mechanism further includes:

[0007] A drive rod is fixedly connected to the output shaft of a drive motor. The drive rod is rotatably connected to a connecting seat, and a number of abrasive discs arranged at equal angles are fixedly connected to the front end of the drive rod.

[0008] An air extraction pipe is connected to the inner cavity of the connecting seat and is connected to an external vacuum cleaner. The drive rod is provided with an air extraction channel that is connected to the inner cavity of the connecting seat, and a dust extraction port connected to the air extraction channel is also provided at the gap between adjacent abrasive plates.

[0009] Furthermore, the drive motor and the connecting seat are both fixedly connected to the base, and a support seat is also fixedly connected to the base. The support seat has a positioning hole for placing the steel pipe to be processed, and the drive rod is located at the center of the positioning hole.

[0010] Furthermore, the dust suction port is connected to the air extraction channel through the front end through hole on the drive rod, and the air extraction channel is connected to the inner cavity of the connecting seat through the rear end through hole on the drive rod.

[0011] Furthermore, the positioning hole is provided with a number of support rollers arranged at equal angles, and the support rollers are movably connected to the support base to support and fix the steel pipe to be processed.

[0012] Furthermore, the support base is provided with a movable groove, the support roller is rotatably connected in the movable groove, and the support roller can also slide and extend within the movable groove. The movable groove is also provided with a support spring, the two ends of which are respectively connected to the support roller and the bottom of the movable groove.

[0013] The advantages of this utility model are: 1. By driving the abrasive disc to rotate through the drive rod, the inner wall of the steel pipe is polished. This not only removes the dust on the inner surface of the steel pipe, but also effectively removes rust or dirt with strong adhesion, resulting in a strong and efficient cleaning effect.

[0014] 2. By setting a dust suction port in the gap between adjacent abrasive pads, and the dust suction port is eventually connected to an external vacuum cleaner, the dust and rust that are removed can be sucked away at the same time, further ensuring the cleaning effect.

[0015] 3. Replacing high-pressure water gun rinsing not only eliminates the need to remove residual water from the steel pipes after cleaning, but also eliminates the wastewater treatment process after cleaning, thus improving efficiency and saving costs.

[0016] 4. The steel pipe to be processed is positioned by the support base and the support rollers set in the support base, which not only ensures the stability of the steel pipe during processing, but also facilitates the back and forth movement of the steel pipe. Attached Figure Description

[0023] Detailed implementation methods and principles

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0025] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0026] The first aspect of this utility model is as follows: Figure 1 and Figure 2 As shown, in order to remove rust and dust from the inner surface of the steel pipe, a drive rod 106 is used to rotate the abrasive disc 107 to polish the inner wall of the steel pipe. When the abrasive disc 107 polishes the inner wall of the steel pipe, it not only sweeps away the dust, but also grinds off rust or strongly adhering dirt, making the inner wall of the steel pipe look brand new.

[0027] Specifically, a drive motor 102 is fixedly connected to the base 101 to drive the entire mechanism to clean the inner surface of the steel pipe. A drive rod 106 is fixedly connected to the output shaft of the drive motor 102, and the drive rod 106 is also rotatably connected to the connecting seat 103. The connecting seat 103 is also fixedly connected to the base 101.

[0028] The abrasive disc 107 is detachably mounted on the front end of the drive rod 106, and several abrasive discs 107 are arranged at equal angles on the front end of the drive rod 106. Therefore, after the drive motor 102 starts working, it can drive the drive rod 106 to rotate. The rotation of the drive rod 106 can also rotate the abrasive disc 107. Since the abrasive disc 107 is attached to the inner wall of the steel pipe, the rotation of the abrasive disc 107 can also grind off the rust or strongly adhering dirt on the inner wall of the steel pipe.

[0029] Preferably, when the abrasive disc 107 is detachably installed on the front end of the drive rod 106, a certain amount of space can be reserved so that the abrasive disc 107 can move outward a certain distance. In this way, when the drive rod 106 rotates, centrifugal force can be generated so that the abrasive disc 107 moves outward and eventually sticks tightly to the inner wall of the steel pipe.

[0030] On the other hand, such as Figure 1 and Figure 3 As shown, a dust suction port 108 is provided at the gap between adjacent abrasive blades 107, an air extraction channel 109 is provided inside the drive rod 106, and a connecting seat cavity 112 is provided in the connecting seat 103. An air extraction pipe 113 is fixedly connected to the connecting seat 103. The outer end of the air extraction pipe 113 is connected to an external vacuum cleaner, while the inner end of the air extraction pipe 113 is connected to the connecting seat cavity 112. In addition, the front end of the air extraction channel 109 is connected to the dust suction port 108 through the front end through hole 110, and the rear end of the air extraction channel 109 is connected to the connecting seat cavity 112 through the rear end through hole 111.

[0031] Therefore, by providing a suction port 108 at the gap between adjacent abrasive pads 107, and by connecting the suction port 108 to an external vacuum cleaner, the dust and rust that are removed can be sucked away at the same time, thus further ensuring the cleaning effect.

[0032] Therefore, the solution of this utility model replaces high-pressure water gun washing, which can not only remove dust from the inner surface of the steel pipe, but also effectively remove rust or strongly adhering dirt, resulting in a strong and efficient cleaning effect. Moreover, compared with high-pressure water gun washing, this solution not only eliminates the need to remove residual water in the steel pipe after cleaning, but also eliminates the wastewater treatment process after cleaning, thus improving efficiency and saving costs.

[0033] On the other hand, such as Figure 3 and Figure 4As shown, a support base 104 is fixedly connected to the base 101. A positioning hole 105 is provided inside the support base 104 for placing the steel pipe to be processed. The drive rod 106 is located at the center of the positioning hole 105. Therefore, when the steel pipe to be processed extends forward through the positioning hole 105, the drive rod 106 and the abrasive plate 107 at its front end will extend into the steel pipe together. Since the steel pipe is precisely positioned within the positioning hole 105, the drive rod 106 being located at the center of the positioning hole 105 is equivalent to the drive rod 106 also being located at the center of the steel pipe.

[0034] Several support rollers 114 arranged at equal angles are also provided in the positioning hole 105. The support rollers 114 are movably connected to the support base 104. The support rollers 114 are used to support and fix the steel pipe to be processed. The support base 104 is provided with a movable groove 115. The support rollers 114 are tumbled in the movable groove 115. The support rollers 114 can also slide and extend within the movable groove 115. The movable groove 115 is also provided with a support spring 116. The two ends of the support spring 116 are respectively connected to the support rollers 114 and the bottom of the movable groove 115.

[0035] The support base 104 and the support roller 114 located within the support base 104 are used to position the steel pipe to be processed, ensuring the stability of the steel pipe during processing. Furthermore, the support roller 114 can roll and slide within the movable groove 115, allowing it to adapt to the movement of the steel pipe as it moves in and out. For example, when the steel pipe moves back and forth, the support roller 114 can rotate with it, making its movement smoother. When the abrasive disc 107 at the front end of the drive rod 106 polishes the inner wall of the steel pipe, the corresponding support roller 114 contracts under pressure and rebounds under the action of the support spring 116, providing damping and buffering. Detailed Implementation

[0036] When cleaning the inner surface of the steel pipe to be processed, first insert the steel pipe to be processed into the positioning hole 105 in the frontmost support 104. At this time, the front end of the drive rod 106 is exactly at the end of the steel pipe to be processed.

[0037] After the above preparations are completed, start the drive motor 102 and the external vacuum cleaner. After the drive motor 102 starts working, it can drive the drive rod 106 to rotate. The rotation of the drive rod 106 can also rotate the abrasive disc 107. Since the abrasive disc 107 is attached to the inner wall of the steel pipe, the rotation of the abrasive disc 107 can also grind off the rust or strongly adhered dirt on the inner wall of the steel pipe.

[0038] When the abrasive disc 107 at the front end of the drive rod 106 grinds the inner wall of the steel pipe to be processed, it can also cause the support roller 114 at the corresponding position to be compressed by force and return to its original position under the action of the support spring 116, thus playing a damping and buffering role.

[0039] The dust and rust removed by the polishing process are sucked away by the external vacuum cleaner through the suction pipe 113, the inner cavity of the connecting seat 112, the rear through hole 111, the suction channel 109, the front through hole 110, and the suction port 108, further ensuring the cleaning effect.

[0040] During the grinding and dust removal process, the steel pipe to be processed needs to be pushed forward continuously so that the inner wall of the steel pipe can be effectively ground and cleaned. As the steel pipe moves forward, the support roller 114 can rotate with the steel pipe to be processed, making its movement smoother.

[0041] Once the inner surface of the steel pipe to be processed has been cleaned, turn off the drive motor 102 and the external vacuuming equipment, and then remove the cleaned steel pipe.

[0042] Based on the above, this utility model uses a drive rod 106 to rotate the abrasive disc 107 to polish the inner wall of the steel pipe. This not only removes dust from the inner surface of the steel pipe but also effectively removes rust or stubborn dirt, resulting in a strong and efficient cleaning effect. Furthermore, a suction port 108 is provided at the gap between adjacent abrasive discs 107, and this suction port 108 is ultimately connected to an external vacuum cleaner. This allows for the removal of dust and rust while simultaneously sucking them away, further ensuring the cleaning effect. Additionally, the support base 104 and the support roller 114 located within the support base 104 are used to position the steel pipe to be processed, ensuring stability during processing and facilitating the forward and backward movement of the steel pipe.
