Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an automatic pipe inner wall treatment device and method. Background Technology

[0002] Currently, rust removal and coating of pipe inner walls are typically performed using manual insertion tools or rotating devices driven by mechanical transmission structures. However, these technical solutions generally suffer from the following problems: On the one hand, existing devices mostly transmit power from the outside of the pipeline to the internal actuator through a mechanical transmission structure, which is not only complex in structure, but also difficult to arrange in long-distance or small-diameter pipelines; On the other hand, mechanical connection structures are prone to interference inside the pipe, affecting the uniformity of processing, and there are problems such as wear and jamming during rotation, which reduce the stability of the equipment. Furthermore, for continuous processing requirements, existing equipment struggles to coordinate rotary processing and axial feed, resulting in low processing efficiency.

[0003] Therefore, it is necessary to provide a new technical solution to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic pipe inner wall treatment device and method, so as to achieve stable and efficient continuous treatment of the pipe inner wall without mechanical connection.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is an automatic pipe inner wall treatment device, comprising: The frame includes a track and a trolley that can move along the track, the trolley being used to support the pipe; An external magnetic field assembly is mounted on the frame and surrounds the outside of the pipe to form a magnetic field that covers the area through which the pipe passes. The actuator is rotatably disposed inside the pipe; A rotary drive assembly includes a coil rotor and a power supply unit for supplying power to the coil rotor. The actuator is connected to the coil rotor, and the coil rotor is kept within the magnetic field range so that it can rotate under the action of the magnetic field when energized, thereby driving the actuator to rotate. A pipeline feeding assembly, mounted on the frame, is used to drive the trolley to move along the track.

[0006] A further improvement of the automatic pipe inner wall treatment device of the present invention is that the trolley includes a trolley body, a wheel set located at the bottom of the trolley body and slidingly engaged with the track, and an arc-shaped support plate located at the top of the trolley body for supporting the pipe, the arc-shaped support plate being arranged along the length direction of the track.

[0007] A further improvement of the automatic pipe inner wall treatment device of the present invention is that the trolley further includes an elastic strap, which is connected to the arc-shaped support plate and is used to lock the pipe supported on the arc-shaped support plate.

[0008] A further improvement of the automatic pipe inner wall treatment device of the present invention is that the pipe feeding assembly includes: The driven rack is connected along its entire length to the bottom of the arc-shaped support plate; A drive motor is connected to the track, and a drive gear is coaxially connected to the motor shaft of the drive motor. The drive gear meshes with the driven rack.

[0009] A further improvement of the automatic pipe inner wall treatment device of the present invention is that the external magnetic field assembly includes two arc-shaped magnets, which are arranged opposite to each other and surround the outside of the pipe. Both arc-shaped magnets are connected to the track through height-adjustable support members. Each support member and the corresponding arc-shaped magnet are connected to a telescopic member that extends and retracts in a direction perpendicular to the length of the track.

[0010] A further improvement of the automatic pipe inner wall treatment device of the present invention is that it also includes a positioning rod, which passes through the pipe and is coaxially arranged with the pipe. The coil rotor is rotatably connected to the positioning rod, and the two ends of the track are respectively connected to the brackets. The two ends of the positioning rod are respectively supported by the two brackets.

[0011] A further improvement of the automatic pipe inner wall treatment device of the present invention is that the actuator includes: An annular mounting bracket is fixedly sleeved on the outer circumference of the coil rotor; Multiple processing units are arranged circumferentially along the annular mounting bracket and are used to contact the inner wall of the pipe to perform rust removal and / or coating treatment on the inner wall of the pipe.

[0012] An automated method for treating the inner wall of a pipe includes the following steps: Step 1: Provide the above-mentioned automatic pipe inner wall treatment device; Step 2: A magnetic field covering the pipe's installation area is formed using an external magnetic field assembly; Step 3: Power is supplied to the coil rotor through the power supply unit, so that the coil rotor generates electromagnetic driving force under the action of the magnetic field and rotates around the pipeline axis, driving the actuator to rotate synchronously; Step 4: While the coil rotor is rotating, the pipe is driven to move axially through the pipe feeding assembly, and the inner wall of the pipe is continuously derusted and / or coated by the synchronous rotation of the actuator.

[0013] Compared with the prior art, the advantages of the present invention are: 1. By using an external magnetic field assembly in conjunction with a coil rotor, the actuator inside the tube can be driven without any mechanical connection between the two, thus avoiding interference and wear problems caused by mechanical transmission structures and improving operational stability; 2. By setting up a pipe feeding assembly, the pipe moves axially while being rotated, thus achieving continuous treatment of the pipe's inner wall and improving processing efficiency and uniformity.

[0018] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0019] The automatic pipe inner wall treatment device and its treatment method of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Please see Figures 1-2 As shown, the automatic pipe inner wall treatment device includes: The frame includes a track 2 and a trolley 3 that can move along the track 2, the trolley 3 being used to support the pipe 6; An external magnetic field assembly is mounted on the frame and surrounds the outside of the pipe 6 to form a magnetic field that covers the area through which the pipe 6 passes. The actuator is rotatably disposed inside the pipe 6; A rotary drive assembly includes a coil rotor 17 and a power supply unit 11 for supplying power to the coil rotor 17. An actuator is connected to the coil rotor 17. The coil rotor 17 is kept within the magnetic field range so that it can rotate under the action of the magnetic field when energized, thereby driving the actuator to rotate. A pipeline feed assembly, mounted on the frame, is used to drive the trolley 3 to move along the track 2.

[0021] By setting a non-contact electromagnetic drive structure between the external magnetic field component and the rotary drive component, mechanical transmission can be bypassed from the inside of the pipe 6, thus avoiding sealing difficulties and structural interference problems caused by the insertion of the drive shaft.

[0022] Specifically, the external magnetic field assembly forms a magnetic field that penetrates the pipe wall radially. When the coil rotor 17 is energized, it generates an electromagnetic torque, causing the coil rotor 17 to rotate continuously around the axis of the pipe 6.

[0023] Specifically, the power supply unit 11 can be introduced into the pipe through a wire, or a slip ring power supply structure can be used to ensure the continuous power supply stability of the coil rotor 17 during rotation.

[0024] Preferably, the trolley 3 includes a trolley body, a wheel set located at the bottom of the trolley body and slidingly engaged with the track 2, and an arc-shaped support plate 4 located at the top of the trolley body for supporting the pipe 6, the arc-shaped support plate 4 being arranged along the length direction of the track 2.

[0025] Specifically, the track 2 is preferably a linear guide or a roller guide structure to reduce the moving resistance of the trolley 3.

[0026] By setting up a moving structure that coordinates track 2 with trolley 3, the pipeline feeding process can be made stable and controllable, thereby preventing the pipeline 6 from shaking or deviating during the processing.

[0027] Specifically, the curved surface of the arc-shaped support plate 4 is provided with an anti-slip layer or rubber pad.

[0028] By setting the anti-slip layer or rubber pad, the friction is increased, ensuring the stability of the pipe 6 and preventing the pipe 6 from sliding relative to the arc-shaped support plate 4.

[0029] Preferably, the trolley 3 also includes an elastic strap 5, which is connected to the arc-shaped support plate 4 and is used to lock the pipe 6 supported on the arc-shaped support plate 4.

[0030] By setting up a combination limiting structure of arc-shaped support plate 4 and elastic strap 5, stable support and locking of pipes 6 of different specifications can be achieved, thereby improving the adaptability of the device.

[0031] Specifically, the elastic strap 5 is an elastic strap or an adjustable strap with a buckle.

[0032] By adjusting the tightness of the elastic strap 5, pipes 6 of different diameters can be fixed, thereby improving adaptability.

[0033] Specifically, there are multiple elastic straps 5, and these multiple elastic straps 5 are spaced apart along the length of the arc-shaped support plate 4.

[0034] By setting multiple elastic straps 5, the limiting effect on the pipe 6 is improved.

[0035] Preferably, the pipeline feed assembly includes: Driven rack 12 is connected along its length to the bottom of the arc-shaped support plate 4; A drive motor 13 is connected to the track 2. A drive gear 14 is coaxially connected to the motor shaft of the drive motor 13. The drive gear 14 meshes with the driven rack 12.

[0036] Specifically, a connecting seat 15 is connected between the drive motor 13 and the track 2.

[0037] By providing the connector 15, the connection basis for the drive motor 13 is improved.

[0038] Specifically, the drive motor 13 is a servo motor or a frequency converter motor. By adjusting the motor speed, the feed speed can be controlled, thereby adapting to different processing conditions.

[0039] Specifically, the rack extends along the length of the track 2, and by providing long-stroke transmission, it enables the trolley 3 to move continuously, thus making it suitable for long pipeline processing.

[0040] By setting up a gear and rack transmission structure, the pipeline feed speed can be controlled, which facilitates matching with the rotation speed inside the pipe.

[0041] Preferably, the external magnetic field assembly includes two arc-shaped magnets 7, which are arranged opposite each other and surround the outside of the pipe 6. Both arc-shaped magnets 7 are connected to the track 2 through height-adjustable support members 8. Each support member 8 is connected to the corresponding arc-shaped magnet 7 by a telescopic member 9 that extends and retracts in a direction perpendicular to the length of the track 2.

[0042] Specifically, the curvature of the arc-shaped magnet 7 is matched with the outer diameter of the pipe 6, thereby increasing the driving force and improving the driving efficiency by increasing the magnetic field coupling.

[0043] Specifically, the telescopic component 9 is a screw adjustment mechanism or a cylinder structure. By adjusting the position of the magnet, the range of magnetic field can be adjusted to adapt to different pipe diameters.

[0044] Specifically, the two arc-shaped magnets 7 form N poles and S poles respectively, and by forming a closed magnetic field loop, a stable magnetic field distribution is achieved, thereby ensuring driving stability.

[0045] By setting an adjustable arc-shaped magnet 7 structure, the range of magnetic field effect can be adjusted, thereby adapting to pipes 6 of different diameters.

[0046] Preferably, it also includes a positioning rod 10, which passes through the pipe 6 and is coaxially arranged with the pipe 6. The coil rotor 17 is rotatably connected to the positioning rod 10. The two ends of the track 2 are respectively connected to the brackets 1, and the two ends of the positioning rod 10 are respectively supported by the two brackets 1.

[0047] Specifically, the coil rotor 17 is rotatably mounted on the positioning rod 10 via a bearing structure, thereby reducing frictional resistance and achieving smooth rotation, thus improving operational stability.

[0048] Specifically, the bracket 1 is an inverted U-shaped seat, and the top of the inverted U-shaped seat is vertically provided with a slot 16 for the positioning rod 10 to be engaged. An adjusting member for adjusting the support height of the positioning rod 10 is connected in the slot 16.

[0049] Specifically, both ends of the positioning rod 10 are equipped with limiting structures to achieve positional stability by limiting axial displacement, thereby preventing movement.

[0050] Specifically, the adjusting component is a screw, and each of the slots 16 has a threaded hole for threaded connection of the screw. The positioning rod 10 is engaged in the slot 16 and supported on the top of the screw. The height of the positioning rod 10 can be adjusted by adjusting the engagement height of the screw.

[0051] By setting a matching structure between the positioning rod 10 and the adjusting component, the rotating components inside the tube are arranged coaxially, thereby avoiding eccentric rotation.

[0052] Preferably, the executable includes: An annular mounting bracket is fixedly sleeved on the outer periphery of the coil rotor 17; Multiple processing units are arranged at circumferential intervals along the annular mounting bracket and are used to contact the inner wall of the pipe 6 to perform rust removal and / or coating treatment on the inner wall of the pipe 6.

[0053] Specifically, the processing unit can be a steel brush, a grinding wheel, a spray nozzle, or a coating roller. By using various processing methods, it can meet different process requirements and thus improve applicability.

[0054] Specifically, the processing unit is connected to the annular mounting frame through an elastic support structure. By adjusting the contact pressure, it can fit the inner wall, thereby improving the processing effect.

[0055] By setting up multiple circumferentially distributed processing units, full coverage processing of the inner wall of pipe 6 is achieved, thereby avoiding processing blind spots.

[0056] An automated method for treating the inner wall of a pipe includes the following steps: Step 1: Provide the above-mentioned automatic pipe inner wall treatment device; Step 2: A magnetic field capable of covering the entire area through which the pipe 6 passes is formed using an external magnetic field assembly; Step 3: Power supply is supplied to the coil rotor 17 through the power supply unit 11, so that the coil rotor 17 generates electromagnetic driving force under the action of the magnetic field and rotates around the pipeline axis, thereby driving the actuator to rotate synchronously. Step 4: While the coil rotor 17 is rotating, the pipe 6 is driven to move axially through the pipe feed assembly, and the inner wall of the pipe is continuously derusted and / or coated by the synchronous rotation of the actuator.
