Description

Technical Field

[0001] This disclosure relates to the field of laser cleaning technology, and more specifically, to a laser cleaning device for the outer wall of a pipe. Background Technology

[0002] In industrial manufacturing, energy transportation, and chemical equipment maintenance, pipelines serve as crucial fluid transport carriers, and their surface cleanliness significantly impacts the safe operation and lifespan of the system. With increasing environmental protection requirements and the growing environmental pollution caused by traditional cleaning methods (such as sandblasting and chemical cleaning), laser cleaning technology, due to its advantages of being non-contact, leaving no media residue, high precision, and allowing for automated control, is gradually becoming an important alternative to traditional cleaning processes.

[0003] Currently, the dust generated by existing laser cleaning equipment during the cleaning process is easily dispersed into the air, affecting the working environment and harming the health of operators. Utility Model Content

[0004] The purpose of this disclosure is to provide a laser cleaning device for the outer wall of pipes to solve the technical problems existing in the related art.

[0005] To achieve the above objectives, this disclosure provides a laser cleaning device for the outer wall of a pipe, including a laser cleaning handpiece, a dust removal hood, a mounting base, and a first suction pipe;

[0006] The mounting base is used to install on the support structure, and the mounting base is provided with the dust removal hood and the laser cleaning tool, with the laser cleaning tool located outside the dust removal hood;

[0007] From top to bottom, the cross-sectional area of ​​the dust removal hood gradually increases. A first dust suction port is formed on the side wall of the dust removal hood. A first opening communicating with the inside of the dust removal hood is provided on the top of the dust removal hood. The first opening is used to allow the laser beam of the laser cleaning handpiece to pass through to the surface of the pipe below the dust removal hood.

[0009] Optionally, the laser cleaning device further includes a second suction tube;

[0010] The dust removal hood is constructed as a hollow frustum structure, and the first dust suction port and the second dust suction port are respectively formed on the two opposite side walls of the dust removal hood.

[0011] One end of the second suction pipe is connected to the second suction port, and the other end of the second suction pipe is used to connect to the suction device.

[0012] Optionally, the laser cleaning device further includes a first support and a position adjustment assembly, and the dust hood includes a top plate and a plurality of side plates surrounding the top plate;

[0013] At least one of the side plates has a second opening that communicates with the first opening, and the first opening and the second opening together define an outlet.

[0014] The top of the mounting base is used to connect with the support structure, one end of the first bracket is connected to the bottom of the mounting base, and the other end of the first bracket is connected to the top surface of the top plate.

[0015] The laser cleaning tool is mounted on the position adjustment component, which is installed at the bottom of the mounting base. The position adjustment component is used to adjust the height and tilt angle of the laser cleaning tool so that the laser beam of the laser cleaning tool can pass through the opening to the surface of the pipe.

[0016] Optionally, the position adjustment assembly includes a second bracket, a third bracket, a locking assembly, and a fixing member;

[0017] The second bracket is vertically arranged, and its upper end is connected to the bottom of the mounting base. The second bracket has an arc-shaped sliding hole and a positioning hole arranged opposite each other, wherein the center of the arc-shaped sliding hole coincides with the center of the positioning hole.

[0018] The third support includes a first segment and a second segment connected in an L-shape. The first segment is vertically arranged and the first segment and the second support are fitted together. The first segment has a plurality of through holes, which are spaced apart along the vertical direction of the first segment.

[0019] The locking assembly includes a positioning element and a mounting element. The positioning element includes a first bolt and a first nut. The bolt shank of the first bolt is used to pass through the positioning hole and the corresponding through hole in sequence to connect with the first nut.

[0020] The mounting component includes a second bolt and a second nut, wherein the bolt shank of the second bolt is used to pass through the arc-shaped sliding hole and the corresponding through hole in sequence to connect with the second nut;

[0021] The fastener is installed on the second section and is configured to secure the laser cleaning tool.

[0022] Optionally, the fastener includes a first fastening part and a second fastening part;

[0023] The first fixing part is connected to the bottom of the second section, and the second fixing part is detachably connected to the first fixing part by fixing bolts;

[0024] The first fixing part has a first slot that can engage the laser cleaning tool, and the second fixing part has a second slot that can engage the laser cleaning tool. The first slot and the second slot are arranged opposite to each other in the vertical direction.

[0025] Optionally, the laser head of the laser cleaning handpiece is positioned higher than the top plate.

[0026] Optionally, the laser cleaning device further includes two stops;

[0027] The two baffles are arranged opposite to each other and connected to the side wall of the dust removal hood. The bottom of the dust removal hood and the two baffles together enclose a cleaning channel that can accommodate the pipe. The cleaning channel is connected to the interior of the dust removal hood.

[0028] The cleaning channel extends in a direction that is parallel to the axis of the pipe.

[0029] Optionally, the barrier is configured as a movable door curtain;

[0030] Each of the aforementioned movable curtains is configured to open in both directions, so that it can open in the direction of movement along the pipe when the pipe compresses the movable curtain;

[0031] In the natural state of each of the movable curtains, the bottom of the dust cover, together with the two baffles, defines the cleaning channel.

[0032] Optionally, the movable door curtain includes multiple panels;

[0033] Each of the plates extends along the extension direction of the cleaning channel, and the plurality of plates are spaced apart in the vertical direction. Adjacent plates are connected by hinges, and the plates located at the first ends of the plurality of plates are used to connect to the outer wall of the dust removal hood.

[0034] Optionally, the length of the plate is greater than the width of the large end of the dust collector hood.

[0035] Through the above technical solution, with the installation of a first suction pipe and a dust removal hood, and since the dust removal hood is installed above the pipe and the first suction pipe connects the dust removal hood to the external suction equipment, the suction equipment can continuously suction the interior of the dust removal hood through the first suction pipe during the cleaning process. This effectively removes dust from inside and below the dust removal hood, preventing dust from spreading into the working environment. Furthermore, the cross-sectional area of ​​the dust removal hood gradually increases from top to bottom, allowing the side walls of the hood to guide and collect rising dust. Specifically, dust generated by the laser cleaning tool on the pipe surface can rise along the inner wall of the dust removal hood and collect at the top. This facilitates dust entering the first suction pipe through the first suction port on the side wall of the dust removal hood, improving the dust collection efficiency and preventing dust from spreading to the surrounding areas of the work area (i.e., the cleaning channel described below). This, in turn, improves the cleanliness of the work site and helps protect the health and safety of operators. Furthermore, since the laser cleaning tool is located outside the dust hood, the dust hood effectively prevents dust generated during the cleaning process from adhering to the laser cleaning tool. It also prevents the high-temperature airflow generated during cleaning from causing impact damage to the laser cleaning tool, thereby extending its service life and reducing optical path deviation or power attenuation problems caused by dust deposition on optical components. In other words, the laser cleaning device provided in this disclosure, through its reasonable spatial layout, can significantly reduce the emission of dust into the surrounding environment during the cleaning process while effectively protecting the laser cleaning tool.

[0044] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0045] In the description of this disclosure, it should be understood that the terms "upper," "lower," "left," "right," "top," "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation, and therefore should not be construed as a limitation of this disclosure. For example, see [link to relevant documentation]. Figure 1 , Figure 1 The area above the plane of the image is considered "above". Figure 1 The direction above in the drawing is "below," and "inside" and "outside" refer to the inside and outside of the corresponding structural outline. Furthermore, terms such as "first" and "second" are used only for descriptive distinction and should not be interpreted as indicating or implying relative importance.

[0046] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0047] like Figures 1 to 4 As shown, this disclosure provides a laser cleaning device for the outer wall of a pipe 50, including a laser cleaning handpiece 10, a dust hood 20, a mounting base 30, and a first suction pipe 40. The mounting base 30 is used to install on a support structure. The dust hood 20 and the laser cleaning handpiece 10 are provided on the mounting base 30. The laser cleaning handpiece 10 is located outside the dust hood 20. From top to bottom, the cross-sectional area of ​​the dust hood 20 gradually increases. A first suction port 22 is formed on the side wall of the dust hood 20. A first opening 21 communicating with the interior of the dust hood 20 is provided on the top of the dust hood 20. The first opening 21 is used to allow the laser beam of the laser cleaning handpiece 10 to pass through to the surface of the pipe 50 below the dust hood 20. One end of the first suction pipe 40 is connected to the first suction port 22, and the other end of the first suction pipe 40 is used to connect to a suction device.

[0048] The laser cleaning handpiece 10 is used to emit a laser to remove dirt or coatings from the surface of the pipe 50. The laser cleaning handpiece 10 is prior art and will not be described in detail here.

[0049] It should be noted that the pipe 50 is moved horizontally under the action of the conveying mechanism (not shown) and stops moving after reaching the designated position. Then, the pipe 50 is rotated about its own axis under the action of the driving mechanism (not shown) so that the laser cleaning handpiece 10 can uniformly clean the entire outer surface of the pipe 50.

[0050] Through the above technical solution, with the first suction pipe 40 and the dust removal hood 20 installed above the pipe 50, and the first suction pipe 40 connecting the dust removal hood 20 to the external suction equipment, the suction equipment can continuously suction the interior of the dust removal hood 20 through the first suction pipe 40 during the cleaning process. This allows the dust inside and below the dust removal hood 20 to be promptly removed from the dust removal hood 20, effectively preventing dust from spreading into the working environment. Furthermore, the cross-sectional area of ​​the dust removal hood 20 gradually increases from top to bottom, enabling the side walls of the dust removal hood 20 to guide and collect the rising dust. That is, the dust generated by the laser cleaning tool 10 during laser cleaning of the surface of the pipe 50 can rise along the inner wall of the dust removal hood 20 and collect at the top of the dust removal hood 20. This allows dust to enter the first suction pipe 40 through the first suction port 22 on the side wall of the dust hood 20, improving the dust collection efficiency of the dust hood 20 and preventing dust from spreading to the surrounding area of ​​the work area (i.e., the cleaning channel 90 below). This improves the cleanliness of the work site and helps protect the health and safety of operators. Furthermore, since the laser cleaning handpiece 10 is located outside the dust hood 20, the dust hood 20 effectively prevents dust generated during the cleaning process from adhering to the laser cleaning handpiece 10. It also prevents the high-temperature airflow generated during the cleaning process from causing impact damage to the laser cleaning handpiece 10, thus extending its service life and reducing optical path deviation or power attenuation problems caused by dust deposition on optical components. In other words, the laser cleaning device provided in this disclosure, through a reasonable spatial layout, can significantly reduce the dispersion of dust into the surrounding environment during the cleaning process while effectively protecting the laser cleaning handpiece 10.

[0051] As one implementation method, such as Figures 1 to 2 As shown, the laser cleaning device also includes a second suction pipe 41. The dust hood 20 is constructed as a hollow frustum structure. A first suction port 22 and a second suction port are formed on the two opposite side walls of the dust hood 20, respectively. One end of the second suction pipe 41 is connected to the second suction port, and the other end of the second suction pipe 41 is used to connect to the suction device.

[0052] Among them, the dust collector hood 20 is constructed as a hollow truncated cone structure, which can increase the airflow channel, guide dust to concentrate upwards and slow down the airflow speed, thereby improving the dust collection efficiency.

[0053] The design of dual suction ports combined with dual suction pipes can increase the total air volume, thereby enhancing dust collection capabilities. In addition, the symmetrical arrangement of the first suction port 22 and the second suction port (not shown) helps to balance the airflow pressure field inside the dust collection hood 20, so as to maintain airflow stability and prevent airflow disturbance (i.e., vortex phenomenon) caused by unilateral suction from affecting dust collection efficiency.

[0054] As one implementation method, such as Figures 1 to 2 As shown, the laser cleaning device also includes a first bracket 60 and a position adjustment assembly 70. The dust cover 20 includes a top plate 23 and a plurality of side plates 24 surrounding the top plate 23. At least one side plate 24 has a second opening 25 communicating with the first opening 21. The first opening 21 and the second opening 25 together define a passage 26. The top of the mounting base 30 is used to connect with a support structure. One end of the first bracket 60 is connected to the bottom of the mounting base 30, and the other end of the first bracket 60 is connected to the top surface of the top plate 23. The laser cleaning handpiece 10 is mounted on the position adjustment assembly 70, which is installed at the bottom of the mounting base 30. The position adjustment assembly 70 is used to adjust the height position and tilt angle of the laser cleaning handpiece 10 so that the laser beam of the laser cleaning handpiece 10 can pass through the passage 26 to the surface of the pipe 50.

[0055] The first bracket 60 provides support and fixation for the dust cover 20, ensuring that the dust cover 20 remains stable and reliable during the laser cleaning process.

[0056] By using the position adjustment component 70, the height of the laser cleaning handpiece 10 relative to the pipe 50 can be adjusted to accommodate pipes 50 of different diameters or shapes. On the other hand, the tilt angle of the laser cleaning handpiece 10 can be adjusted according to the actual situation, thereby changing the incident angle of the laser beam and allowing the laser beam to more accurately irradiate the surface of the pipe 50, thus improving cleaning efficiency and quality.

[0057] The opening 26 expands the passage space for the laser beam, preventing it from being blocked due to positional shift. It also enhances the adjustability of the height and tilt angle of the laser cleaning handpiece 10, thereby improving cleaning flexibility.

[0058] It should be understood that the opening 26 has two forms. One is an opening formed at the top edge of the dust hood 20, that is, the first opening 21 is located at the edge of the top plate 23, and the second opening 25 is located at the upper edge of the adjacent side plate 24. The other is an opening formed at the top corner of the dust hood 20, that is, the first opening 21 is located at a corner of the top plate 23, and the second opening 25 is located at the intersection corner of the two adjacent side plates 24.

[0059] Preferably, the opening 26 is located at the top edge of the dust removal hood 20. This arrangement can accommodate a wider range of laser beam deflection angles, making it suitable for cleaning needs of various pipe diameters and different tilt angles.

[0060] As one implementation method, such as Figures 3 to 4 As shown, the position adjustment assembly 70 includes a second bracket 71, a third bracket 72, a locking assembly, and a fixing member 73. The second bracket 71 is vertically arranged, and its upper end is connected to the bottom of the mounting base 30. The second bracket 71 has an arc-shaped sliding hole 711 and a positioning hole 712 arranged vertically opposite each other, wherein the center of the arc of the arc-shaped sliding hole 711 coincides with the center of the positioning hole 712. The third bracket 72 includes a connected L-shaped first segment 721 and a second segment 722. The first segment 721 is vertically arranged, and the first segment 721 and the second bracket 71 are fitted together. The first segment 721 has multiple through holes 723 and 724. 3. The locking assembly is arranged at intervals along the vertical direction of the first segment 721. It includes a positioning member (not shown) and a mounting member (not shown). The positioning member includes a first bolt (not shown) and a first nut (not shown). The bolt shank of the first bolt is used to pass through the positioning hole 712 and the corresponding through hole 723 in sequence to connect with the first nut. The mounting member includes a second bolt (not shown) and a second nut (not shown). The bolt shank of the second bolt is used to pass through the arc-shaped sliding hole 711 and the corresponding through hole 723 in sequence to connect with the second nut. The fixing member 73 is installed in the second segment 722. The fixing member 73 is configured to fix the laser cleaning hand tool 10.

[0061] With the positioning element in place, the bolt shank of the first bolt passes sequentially through the positioning hole 712 (on the second bracket 71) and the corresponding through hole 723 (on the first segment 721, near and aligned with the positioning hole 712) and is threadedly connected to the first nut. At this time, the first bolt and the first nut are in a pre-locked state (i.e., they have a certain tightening force but can still be finely adjusted). This design, on the one hand, allows for height locking of the laser cleaning tool 10 on the third bracket 72, preventing vertical displacement of the third bracket 72 during the cleaning process. On the other hand, it allows the third bracket 72 to rotate within a certain range around the positioning element as its central axis. Thus, the laser cleaning tool 10 on the third bracket 72 can also change its tilt angle with the third bracket 72, thereby achieving precise control of the laser beam incident angle.

[0062] With the installed mounting components, the bolt shank of the second bolt can pass sequentially through the arc-shaped sliding hole 711 (on the second bracket 71) and the corresponding through hole 723 (the through hole 723 on the first segment 721 that is close to and aligned with the arc-shaped sliding hole 711). In the unlocked state, this allows the third bracket 72 to rotate around the arc center (positioning component) to adjust the tilt angle. After adjusting the tilt angle of the laser cleaning handpiece 10, the first nut and the second nut can be tightened sequentially to fix the angle of the laser cleaning handpiece 10.

[0063] As one implementation method, such as Figures 3 to 4 As shown, the fixing member 73 includes a first fixing part 731 and a second fixing part 732. The first fixing part 731 is connected to the bottom of the second segment 722, and the second fixing part 732 is detachably connected to the first fixing part 731 by fixing bolts. The first fixing part 731 has a first slot 733 that can engage the laser cleaning hand tool 10, and the second fixing part 732 has a second slot 734 that can engage the laser cleaning hand tool 10. The first slot 733 and the second slot 734 are arranged opposite to each other in the vertical direction.

[0064] The first fixing part 731 and the second fixing part 732 are detachably connected by fixing bolts, which facilitates the replacement or maintenance of the laser cleaning hand tool 10.

[0065] Specifically, when installing the laser cleaning handpiece 10, firstly, the laser cleaning handpiece 10 can be placed on the first slot 733. Then, the second fixing part 732 is placed so that the second slot 734 is aligned with the first slot 733 and clamps the handpiece. Then, the second fixing part 732 is fastened to the first fixing part 731 using fixing bolts, thereby achieving stable clamping and positioning.

[0066] When it is necessary to remove the laser cleaning handpiece 10 from the third bracket 72, first, loosen the fixing bolts and remove the second fixing part 732. Then, remove the laser cleaning handpiece 10 from the first slot 733. The entire installation and disassembly process is simple and quick, suitable for scenarios where different handpiece models are frequently changed.

[0067] As one implementation method, such as Figures 1 to 2 As shown, the laser head of the laser cleaning handpiece 10 is positioned higher than the top plate 23.

[0068] The relatively high position of the laser head allows for more flexible angle adjustments.

[0069] As one implementation method, such as Figures 1 to 2As shown, the laser cleaning device also includes two baffles 80, which are arranged opposite to each other and connected to the side wall of the dust removal hood 20. The bottom of the dust removal hood 20 and the two baffles 80 together enclose a cleaning channel 90 that can accommodate the pipe 50. The cleaning channel 90 is connected to the interior of the dust removal hood 20. The extending direction of the cleaning channel 90 is set to be parallel to the axis of the pipe 50.

[0070] The two baffles 80 serve two purposes: firstly, they enhance the spatial constraint of the cleaning channel 90, helping to prevent dust from escaping from both ends of the channel, thereby improving the overall dust removal effect and protecting the health of operators; secondly, they help maintain a negative pressure environment inside the dust collection hood 20, thus improving dust collection efficiency.

[0071] Since the pipe 50 enters the cleaning channel 90 horizontally, in order to achieve dynamic avoidance of the stop 80, as one implementation method, such as... Figures 1 to 2 As shown, the baffle 80 is constructed as a movable curtain, and each movable curtain is set to open in both directions so that it can open in the direction of movement along the pipe 50 when the pipe 50 squeezes the movable curtain. In the natural state of each movable curtain, the bottom of the dust hood 20 and the two baffles 80 together define the cleaning channel 90.

[0072] The two-way opening design of the movable door curtain allows it to swing or deform in two opposite directions according to the action of external force, enabling dynamic avoidance of the pipe 50 when it is inserted into the cleaning channel 90 and when it is withdrawn from the cleaning channel 90.

[0073] When the movable door curtain is in its natural state (i.e., without external force), it can remain closed, thus maintaining the sealing and airflow stability of the cleaning channel 90.

[0074] Optionally, the stop 80 can be made of flexible material or a deformable structure composed of multiple hinged strips, and this disclosure does not impose any limitations on it.

[0075] An embodiment of the stop 80 being a deformable structure composed of multiple hinged strips, such as... Figures 1 to 2 As shown, the movable door curtain includes multiple panels 81, each extending along the direction of the cleaning channel 90. The panels 81 are spaced vertically, and adjacent panels 81 are connected by hinges 82. The panel 81 at the head of each panel 81 is used to connect to the outer wall of the dust collection hood 20. This design allows the movable door curtain to rotate flexibly and open bidirectionally (left and right) under external force. Furthermore, when no external force is applied, the movable door curtain can maintain a vertically closed state through self-realignment.

[0076] Specifically, when the rotating pipe 50 is inserted horizontally into the cleaning channel 90, it can compress the nearest movable curtain. At this time, the adjacent plates 81 at the bottom of the nearest movable curtain can rotate relative to each other through the hinge 82, allowing the nearest movable curtain to open towards the inside of the cleaning channel 90. The opening size of the nearest movable curtain can automatically adapt to the diameter of the pipe 50 without manual intervention. After the pipe 50 moves to the appropriate position, the nearest movable curtain loses the external pressure of the pipe 50 and returns to its natural vertical state under its own gravity, so that the laser cleaning handpiece 10 can perform laser cleaning on the pipe 50 in the cleaning channel 90.

[0077] After cleaning is completed, the pipe 50 continues to move forward and horizontally, squeezing the movable curtain on the other side. At this time, the adjacent plates 81 at the bottom of the movable curtain on the other side can rotate relative to each other through the hinge 82, so that the movable curtain on the other side can open in the direction away from the cleaning channel 90, so that the pipe 50 exits the cleaning channel 90, and the movable curtain on the other side loses the external force of the pipe 50 and returns to its natural vertical state under its own gravity.

[0078] As one implementation method, such as Figure 2 As shown, the length of plate 81 is greater than the width of the large end of dust hood 20.

[0079] The longer plate 81 helps maintain airflow stability within the cleaning channel 90, which can further reduce dust escape.

[0080] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0081] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0082] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
