Description

Technical Field

[0001] This utility model relates to the field of stainless steel processing technology, specifically to a direct plug cleaning device suitable for the inner wall of stainless steel pipes. Background Technology

[0002] Stainless steel pipes, as a type of corrosion-resistant and high-strength pipe material, are widely used in industries such as food processing, pharmaceutical production, petrochemical transportation, and metallurgical fluid systems. In practical applications, because their interiors are frequently in contact with liquids, gases, or particulate media, scale, grease, deposits, or impurities easily form on the inner walls. If not cleaned regularly, this can lead to reduced transportation efficiency, decreased product quality, and even problems such as pipe blockage and corrosion. Therefore, efficient cleaning equipment for the inner walls of stainless steel pipes has become a common supporting facility in related industries.

[0003] In existing technologies, the following methods are commonly used to clean the inner wall of stainless steel pipes: one is to manually pull a rotating brush head into the pipe and scrub it back and forth; the other is to use a high-pressure water gun or chemical solvent to rinse and clean the pipe; and the third is to set up an external rotating motor to drive a flexible steel wire brush to perform a self-rotating scrubbing operation through the pipe.

[0004] However, the above technical solutions still have the following technical defects and shortcomings:

[0005] Manual traction cleaning is inefficient and labor-intensive. Furthermore, it presents operational limitations such as difficulty in accessing long-distance or curved pipelines and resistance to backflow, which seriously affect work efficiency and cleaning quality.

[0006] Chemical or high-pressure flushing methods are highly dependent on the structure and have problems such as high requirements for equipment sealing, high environmental risks, and incomplete cleaning, especially when removing firmly attached impurities.

[0007] Some rotating brush heads have a simple structural design and lack a coordinated control mechanism for propulsion and rotation, which can easily lead to problems such as uneven brushing and poor contact. In particular, when encountering pipe structures with different diameters or stepped connections, the cleaning tool cannot effectively fit, resulting in cleaning residue.

[0008] In summary, existing stainless steel pipe inner wall cleaning devices generally suffer from problems such as non-compact structure, poor cleaning effect, weak adaptability, and low degree of automation. There is an urgent need for a new type of device that can achieve linkage between axial propulsion and rotational cleaning, has a compact structure, strong adaptability, and is easy to operate, so as to meet the actual needs of modern industry for high-efficiency, low-maintenance, and highly adaptable pipe cleaning operations. Utility Model Content

[0009] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0010] Therefore, the technical solution adopted by this utility model is as follows: a direct-insertion cleaning device suitable for the inner wall of stainless steel pipes, including a drive seat, a slide, a main shaft, a cleaning probe, a cleaning brush, a ball screw pair, a rotary gear set, and a pipe delivery seat for pipe positioning and conveying. The cleaning probe is driven by the slide and can be pushed axially along the stainless steel pipe, while simultaneously achieving self-rotation cleaning through a main shaft linkage structure. A first drive motor is fixedly installed on the side of the drive seat, and a second drive motor is fixedly installed on the bottom surface, respectively used to realize the linear drive of the slide and the rotational output of the main shaft. Specifically, the first drive motor drives the screw to rotate, and the ball screw sleeve provided on the slide engages with the screw thread, thereby realizing the linear sliding of the slide on the drive seat, driving the cleaning probe to advance along the pipe direction. Specifically, this structure realizes the axial insertion and positioning stroke adjustment of the cleaning brush, ensuring consistent cleaning depth.

[0011] In a preferred embodiment, the configuration is further as follows: a keyed slide rod is fixedly connected to one end of the main shaft, a sliding gear is sleeved on the outside of the keyed slide rod, and a keyway groove is formed on the inner wall to cooperate with the keyed structure, ensuring that it can move axially during rotation. A second drive motor drives the slide gear to rotate through its output bevel gear meshing with it, thereby driving the main shaft and the cleaning probe to rotate, which in turn drives the cleaning brush set at the end of the probe to achieve rotational cleaning of the inner wall of the pipe. Specifically, the main shaft structure can advance synchronously with the slide while rotating, ensuring that the cleaning path and contact surface are uniform and continuous.

[0012] In a preferred embodiment, the cleaning brush is further configured as follows: It is a tapered steel wire roller brush structure, facilitating insertion into the interior of stainless steel pipes, exhibiting good fit and wear resistance, and is suitable for cleaning pipe sections with varying diameters or complex structures. The cleaning brush is threaded or interference-fitted to the end of the cleaning probe, ensuring stability and safety during operation. Specifically, this structure effectively removes scale, grease, metal deposits, and other contaminants, improving cleaning quality.

[0013] In a preferred embodiment, the slide block, main shaft, and ball screw sleeve are integrated into a single assembly, simultaneously achieving linear propulsion and rotational linkage; the slide sleeve gear, keyed slide rod, and transmission bevel gear structure are arranged coaxially, resulting in a short transmission path, high stability, and facilitating miniaturized packaging. Specifically, this structure improves transmission efficiency, reduces axial runout error, and enhances operational stability.

[0014] In a preferred embodiment, the pipe conveying seat is further configured as follows: It includes a fixed seat and a liftable pressure seat, with several symmetrically arranged support rollers between the fixed seat and the pressure seat for clamping and stabilizing the conveying of the stainless steel pipe. The cleaning probe is arranged parallel to the pipe conveying seat, and its sliding direction is consistent with the axis of the stainless steel pipe, ensuring coaxial connection of the cleaning action. Specifically, this structure facilitates rapid positioning and pipe introduction, effectively improving operational efficiency.

[0015] Based on the above structural configuration, this utility model utilizes a dual-motor control system—a first drive motor driving the sliding block to slide and a second drive motor driving the main shaft to rotate—to achieve synchronous rotation and propulsion of the cleaning probe inside the stainless steel pipe. This drives the cleaning brush to continuously, evenly, and efficiently clean the inner wall of the pipe. The structural design is reasonable, with key components working together efficiently through ball bearing pairs, keyed gears, and countershaft linkages. This not only improves the accuracy and reliability of the device's operation but also effectively adapts to the cleaning needs of pipes of different diameters and lengths.

[0016] The beneficial effects achieved by this utility model are as follows:

[0017] 1. In this utility model, by setting up a combined structure of slide block, ball screw pair and main shaft, the axial precise advancement of cleaning probe inside stainless steel pipe is realized. Combined with the coaxial linkage structure of sliding sleeve gear and keyed slide rod, the cleaning probe can complete self-rotation brushing during the forward process, thereby greatly improving the efficiency and uniformity of inner wall cleaning, and avoiding the cleaning dead corners and repeated operation problems existing in traditional cleaning methods.

[0018] 2. In this utility model, the cleaning brush adopts a conical steel wire roller brush structure, which can be smoothly inserted into stainless steel pipes of different diameters or with variable diameter sections. It has strong wall adhesion and good wear resistance, and is suitable for a variety of complex working conditions. At the same time, combined with the lifting and clamping structure of the pipe conveying seat, it effectively positions and conveys the stainless steel pipe, improves the stability and automation of the cleaning operation, reduces the need for manual intervention and labor intensity, and has a compact overall structure, making it suitable for continuous operation in industrial sites.

[0026] 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 and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0028] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a direct-plug cleaning device suitable for the inner wall of stainless steel pipes.

[0029] Combination Figures 1-4 As shown, this utility model provides a direct-plug cleaning device for the inner wall of stainless steel pipes, comprising: a drive base 100, a pipe conveying base 200, a cleaning probe 300, and a slide 130. The slide 130 is slidably mounted on the upper surface of the drive base 100, used to drive the cleaning probe 300 forward along the axial direction of the stainless steel pipe. A first drive motor 110 is fixedly mounted on the side of the drive base 100, and a second drive motor 120 is fixedly mounted on the bottom surface. The first drive motor 110 provides sliding drive, and the second drive motor 120 provides rotational drive.

[0030] like Figure 2 As shown, a main shaft 140 is provided inside the drive base 100. One end of the main shaft 140 is fixedly connected to a keyed slide rod 141, and the outer surface of the keyed slide rod 141 is provided with several keyed structures. A sliding sleeve gear 150 is slidably sleeved on the surface of the keyed slide rod 141. The inner wall of the sliding sleeve gear 150 is provided with a keyway groove that mates with the keyes of the keyed slide rod 141, ensuring rotational transmission while allowing axial sliding.

[0031] The output end of the second drive motor 120 is connected to an output bevel gear 121, which meshes with the sliding sleeve gear 150, thereby driving the sliding sleeve gear 150 to rotate when the motor is running, and driving the main shaft 140 to rotate synchronously through the keyed sliding rod 141.

[0032] like Figure 3 As shown, the surface of the main shaft 140 is provided with transmission teeth 320, which are connected to the cleaning probe 300. The transmission teeth 320 can drive the cleaning probe 300 to rotate synchronously. A cleaning brush 310 is fixedly connected to the end of the cleaning probe 300 away from the main shaft 140. The cleaning brush 310 is a steel wire roller brush with a tapered head structure at the end, which is used to more efficiently probe into and adhere to the inner wall of the stainless steel pipe.

[0033] like Figure 4 As shown, a lead screw 111 is fixedly connected to the output end of the first drive motor 110. The lead screw 111 is a ball screw structure, which passes through the main shaft 140 and is arranged coaxially. A threaded sleeve 131 is fixedly installed on the surface of the slide 130. The threaded sleeve 131 is a ball threaded sleeve structure, which is sleeved on the outside of the lead screw 111 and engages with its threads. When the first drive motor 110 rotates, it drives the lead screw 111 to rotate, which in turn causes the threaded sleeve 131 to drive the slide 130 to slide along the surface of the drive seat 100, thereby realizing the reciprocating advance of the cleaning probe 300 inside the pipe.

[0034] As the cleaning probe 300 advances along the pipeline, it rotates synchronously under the drive of the main shaft 140. The cleaning brush 310 comes into contact with the inner wall of the stainless steel pipe and removes the attached substances, forming a dual cleaning action of rotational cleaning and axial insertion.

[0035] like Figure 1 and Figure 2 As shown, the pipe conveying seat 200 is located in front of the cleaning probe 300 and includes a fixed structure and a vertically lifting and lowering pressing structure. Several bearing rollers 210 are rotatably mounted on the opposing surfaces of the fixed seat and the pressing seat, used to clamp and convey the stainless steel pipe to be cleaned. In actual use, the bearing rollers 210 can be connected to an external motor for rolling drive. Through the rotation and pressing action of the bearing rollers 210, precise positioning and stable support of the pipe can be achieved.

[0036] Furthermore, the cleaning probe 300 is arranged parallel to the pipe conveying seat 200, and its axial advancement direction is consistent with the arrangement direction of the stainless steel pipe, thereby ensuring the coaxial consistency and operational stability of the cleaning action.

[0037] Through the above structure, the coordinated control of the first drive motor 110 and the second drive motor 120 enables the cleaning probe 300 to achieve synchronous "axial advancement + rotational brushing" linkage action. The user can set the advancement stroke of the slide 130 through the electronic control system to achieve deep cleaning of the inner wall of stainless steel pipes of different lengths.

[0038] In summary, this utility model, through the sliding block 130, main shaft 140, lead screw 111 and their transmission cooperation, enables the cleaning probe 300 to have controllable propulsion and rotation functions. Combined with the steel wire conical roller brush, it realizes efficient and directional direct-plug cleaning of the inner wall of stainless steel pipes, significantly improving cleaning efficiency, reducing manual labor intensity, and is compact in structure and easy to operate. It is suitable for the inner wall treatment needs of various stainless steel long pipes in industries such as metallurgy, food, and medicine.

[0039] Working principle and usage process of this utility model:

[0040] This utility model provides a direct-plug cleaning device suitable for the inner wall of stainless steel pipes. Through the cooperation of the drive seat 100, slide seat 130, cleaning probe 300, pipe conveying seat 200 and their internal transmission structure, it realizes efficient and directional cleaning of the inner wall of long-distance stainless steel pipes.

[0041] During use, the operator first places the stainless steel pipe on the pipe conveying seat 200. The bearing roller 210 between the fixed seat and the pressure seat axially clamps and conveys the stainless steel pipe. Then, the first drive motor 110 is turned on, and its output shaft drives the lead screw 111 to rotate. The ball screw 111 cooperates with the ball sleeve 131, so that the sleeve 131 drives the slide 130 to slide linearly along the pipe axis on the drive seat 100, so that the cleaning probe 300 can be axially inserted into the inside of the stainless steel pipe and perform reciprocating lateral movement.

[0042] The slide block 130 is fixedly connected to the main shaft 140. The main shaft 140 is engaged with the sliding sleeve gear 150 via a keyed slide rod 141 and can move synchronously with the slide block 130. The second drive motor 120 drives the output bevel gear 121 to rotate, meshing with the sliding sleeve gear 150 to drive the main shaft 140 to rotate. The main shaft 140 is linked with the cleaning probe 300 through the transmission teeth 320 on its surface, causing the cleaning probe 300 to rotate synchronously.

[0043] As the cleaning probe 300 rotates, the cleaning brush 310 at its front end begins to contact the inner wall of the stainless steel pipe and brush away the deposits. The cleaning brush 310 adopts a tapered steel wire roller brush structure, which facilitates the insertion of the end of the cleaning brush 310 into the inner side of the stainless steel pipe. At the same time, the cleaning probe 300 as a whole follows the slide 130 to advance axially, realizing the dual cleaning action of the cleaning brush 310 rotating and advancing axially inside the pipe.

[0044] The entire cleaning process can be adjusted according to the length of the pipe by sliding the slide 130. The operation of the two motors is coordinated by controlling the movement of the program, which improves cleaning efficiency and avoids the equipment damage and labor intensity caused by traditional manual probing or reverse pulling cleaning.

[0045] This invention utilizes a "rotation + propulsion" linkage control method to achieve continuous, efficient, and uniform cleaning of the inner wall of stainless steel pipes. It effectively solves the problems of complex operation, incomplete cleaning, and poor human adaptability in existing technologies. It is suitable for the inner wall cleaning process of large-diameter or medium-to-long-distance stainless steel conveying pipes in industries such as metallurgy, chemical industry, and food industry.
