Abstract
Description
Technical Field
[0001] This utility model belongs to the field of industrial cleaning technology and relates to a steel pipe inner wall cleaning device. Background Technology
[0002] During the production of steel pipes, impurities such as oil, iron filings, and scale accumulate on the inner wall. Without effective cleaning, these impurities can affect subsequent processing quality and product performance. Traditional methods, such as inserting cloth into one end of the pipe and allowing air to pass through, cannot thoroughly clean the inner wall, leaving cleaning blind spots and failing to achieve 360° all-around cleaning. They are also ineffective at cleaning stubborn dirt. Currently, most companies use manual cleaning, which is inefficient, labor-intensive, and yields inconsistent cleaning results. Existing automated cleaning equipment is often complex in structure, expensive, and difficult to adapt to the cleaning needs of different steel pipe specifications, exhibiting poor versatility.
[0003] Therefore, there is an urgent need for a steel pipe inner wall cleaning device that can achieve efficient and automated cleaning of the inner wall of steel pipes, which is of great significance. Summary of the Invention

[0014] Furthermore, the steel pipe support mechanism includes a support frame and a transmission bracket. The support frame provides stable support for the steel pipe and is located on the transmission bracket, which is fixed to the transverse conveyor chain mechanism.
[0015] The transverse conveyor chain mechanism includes a conveyor motor, a conveyor shaft, a gear, and a chain. The conveyor motor is connected to the conveyor shaft via a second coupling. The gear is mounted on the conveyor shaft. The chain meshes with the gear. The other end of the chain is mounted on a sprocket.

[0016] The technical concept of this utility model is as follows: The support mechanism includes a motor base and a horizontal slide, used to install and fix the stepper motor and support the entire inner wall cleaning module. Simultaneously, through the cooperation of the ball screw and the stepper motor, it achieves horizontal movement and precisely adjusts the positional relationship with the steel pipe.

The transverse conveying chain mechanism includes a conveying motor, a conveying shaft, gears, and a chain. The conveying motor and the conveying shaft are connected by a second coupling, which drives the gears to rotate, thereby driving the chain to move laterally, accurately conveying the steel pipe to be cleaned to the working position of the inner wall cleaning module, and removing the cleaned steel pipe from the working position after cleaning. By adopting the above technical solution, the transverse transport of steel pipes can be completed, and the control of the conveying motor can realize a large-scale steel pipe cleaning process.

[0029] The present invention will now be further described with reference to the accompanying drawings.
[0030] Reference Figures 1 to 7 A steel pipe inner wall cleaning device includes an inner wall cleaning module and a steel pipe transverse conveying module. The inner wall cleaning module includes a support mechanism 1, a mechanical claw mechanism 2, an adjustable telescopic mechanism 3, and an adaptive pipe mechanism 4. The support mechanism 1 is connected to the mechanical claw mechanism 2, the mechanical claw mechanism 2 is connected to the rear end of the adjustable telescopic mechanism 3, and the front end of the adjustable telescopic mechanism 3 is connected to the adaptive pipe mechanism 4. The steel pipe transverse conveying module includes a steel pipe support mechanism 6 and a transverse conveying chain mechanism 5. The steel pipe support mechanism 6 is located on the transverse conveying chain mechanism 5, and the steel pipe to be cleaned is located on the steel pipe support mechanism 6. In the cleaning state, the adjustable telescopic mechanism 3 and the adaptive pipe mechanism 4 are located inside the steel pipe to be cleaned.
[0031] like Figure 2 As shown, the support mechanism 1 consists of a motor base 1-2 and a horizontal slide 1-1. The motor base 1-2 is used for...
[0032] The stepper motor 1-3 is fixed in place to ensure its horizontal position. The horizontal slide 1-1 supports the stepper motor 1-3, the mechanical claw mechanism 2, the telescopic mechanism 3, and the adaptive pipe mechanism 4, while enabling the entire cleaning mechanism to move horizontally, thereby better adjusting the position of the mechanism and the steel pipe. The ball screw 1-5 is connected to the stepper motor 1-3 through the first coupling 1-4, and its forward and reverse rotation can be controlled to convert the circular motion of the stepper motor 1-3 into the linear motion of the first slider 2-2.
[0033] like Figure 3 As shown, in the mechanical claw mechanism 2, the first base 2-1 is used to fix the overall position of the mechanism. The first slider 2-2 reciprocates linearly, driving the adjustable telescopic mechanism 3 to complete the reciprocating cycle through the connecting piece 2-3, the double-sided Y-shaped connector 2-5, the single-sided Y-shaped connector 2-6, and the claw connector 2-7 in sequence. Both sides of the first slider are hinged to one end of the connecting piece. The other end of the connecting piece is hinged to one end of the double-sided Y-shaped connector 2-5 via a pin 2-4. One end of the single-sided Y-shaped connector 2-6 is hinged to the front end of the first base 2-1. The other ends of the double-sided Y-shaped connector 2-5 and the single-sided Y-shaped connector 2-6 are respectively hinged to the claw connector 2-7.
[0034] like Figure 4 As shown, the adjustable telescopic mechanism 3 includes a telescopic fence 3-2, a connecting pin 3-1, a support pin 3-3, and a flexible water pipe 3-4. The adjustable telescopic mechanism is connected to the claw connector 2-7 of the mechanical claw mechanism 2 through the connecting pin 3-1. In addition to supporting the entire telescopic mechanism, the support pin 3-3 is also used to fix the flexible water pipe 3-4. Furthermore, the size and number of telescopic fences 3-2 can be adjusted to adapt to steel pipes of different lengths and diameters.
[0035] like Figure 5 As shown, the second base 4-1 of the adaptive pipe mechanism 4 is movably connected to the end of the adjustable telescopic mechanism 3 via a T-shaped connector 4-7. The second slider 4-2 is slidably mounted on the guide rail of the base 4-1. The slider 4-2 and the moving rod 4-4 are respectively hinged at both ends of the cross bracket 4-3, and a wheel 4-5 is installed at the end of the moving rod 4-4. When the mechanism enters the steel pipe, the wheel 4-5 is squeezed by the inner wall of the steel pipe, pushing the moving rod 4-4, which in turn moves the slider 4-2 along the guide rail via the cross bracket 4-3, automatically adjusting the extension to adapt to the pipe diameter. High-pressure water flows through the flexible water pipe 3-4 at the rear end. The centrifugal force and reaction force generated when the water flows through the nozzle drive the rotating nozzle 4-6, which reciprocates in conjunction with the telescopic mechanism to achieve spiral cleaning.
[0036] Steel pipe transverse conveying module combined Figure 6 and Figure 7The system includes a steel pipe support mechanism 6 and a transverse conveyor chain mechanism 5. In the steel pipe support mechanism 6, a support frame 6-2 provides stable support for the steel pipe. Two transmission brackets 6-1 are used to fix the support frame 6-2 and connect to the conveyor chain 5-5. The transverse conveyor chain mechanism 5 includes a gear chain device and a transmission device. The transmission device is connected to the conveyor motor 5-1 and the conveyor shaft 5-3 by a coupling 5-2, thereby driving the rotation of the gear 5-4, which meshes with the chain 5-5. When the gear 5-4 rotates, it drives the meshing chain 5-5 to move laterally along a defined trajectory. The transmission brackets 6-1 are fixed to the chain 5-5 and move laterally synchronously with the chain, thus supporting the steel pipe through the support frame 6-2 and achieving transverse transport of the steel pipe.
[0037] During operation, the transverse steel pipe conveying module transports the steel pipe to be cleaned to the working position of the inner wall cleaning module. The inner wall cleaning module controls the stepper motors 1-3 to rotate forward and backward, driving the mechanical claw mechanism 2 to pull the telescopic mechanism 3 to complete the telescopic cycle. Simultaneously, the adaptive pipe mechanism 4 connects the flexible water pipe 3-4 and the rotating nozzle 4-6, adjusting its extension diameter to adapt to the steel pipe diameter. The motor speed is adjusted by the control system to complete the cleaning cycle. After cleaning, the transverse steel pipe conveying module removes the cleaned steel pipe from the working position.
[0038] The embodiments described in this specification are merely examples of implementations of the inventive concept and are for illustrative purposes only. The scope of protection of this utility model should not be considered limited to the specific forms described in these embodiments; rather, it extends to equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
