Description

Technical Field

[0001] This invention relates to the field of cutting technology, specifically to a steam pipe cutting machine with positioning function. Background Technology

[0002] It is mainly used in the installation, maintenance, and renovation of steam pipelines in industries such as petroleum, chemical, power, and heating. For example, during the laying of steam pipelines in thermal power plants, precise cutting of the pipelines is required to ensure the sealing and stability of the pipeline connections; during the maintenance of steam pipelines in chemical plants, this type of cutting machine with positioning function is also needed to accurately cut the damaged pipeline sections in order to replace them with new pipeline sections.

[0003] Existing pipe cutting machines generate a large amount of debris and irritating gases when cutting pipes, which can pose a potential hazard to human health. Therefore, a new design has been developed to address this issue. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a steam pipe cutting machine with positioning function, including a cutting device, a positioning device fixedly connected to the outside of the cutting device, and a processing device fixedly connected to the side of the cutting device away from the positioning device.

[0005] The cutting device includes a cutting base, which clamps the pipe using a positioning device to fix the pipe, thereby improving cutting quality, preventing shaking during cutting, reducing pipe vibration and component collisions, reducing component wear, and extending component lifespan. A cutting frame is fixedly connected to one side of the top of the cutting base, and a machine body is fixedly connected to the top of the cutting frame. A lead screw is rotatably connected to the inner side of the machine body, and a servo motor is fixedly connected to the outer side of the machine body. The servo motor controls the lead screw to rise and fall within the machine body, thereby controlling the height of the circular saw to meet subsequent cutting requirements. A circular saw is fixedly connected to the outer side of the lead screw, which is prone to producing fragments during circular saw cutting. The chipping and gas are cleaned and collected by a processing device, and the gas is filtered to optimize the working environment and reduce safety hazards. A conveyor is fixedly connected to the side of the cutting base away from the cutting frame. The pipe enters from one side of the conveyor and moves towards the circular saw through the conveyor, thereby achieving automatic material conveying, reducing manual support and movement, and improving work efficiency. A protective plate is fixedly connected to the top of the conveyor, and limiting mechanisms are fixedly connected to both sides of the outer side of the protective plate. During the conveying process, the limiting mechanisms contact the surface of the pipe to guide the movement of the pipe, reduce the space for pipe swaying, and prevent excessive shaking during the conveying process, so as to prevent affecting the subsequent cutting effect.

[0006] Preferably, the limiting mechanism includes a limiting frame, with a first electric push rod fixedly connected to the outer side of the limiting frame. The electric push rod controls the limiting housing to approach the pipe, thereby achieving the function of fitting the pipe. By fitting the pipe, the movement space of the pipe inside the conveyor is limited. On the one hand, this avoids collisions between the pipe and components, preventing pipe bending from affecting the cutting effect. On the other hand, it reduces the vibration amplitude of the pipe, making it easier to position and fix the subsequent components, and reducing the difficulty of subsequent fixing. A limiting housing is fixedly connected to one side of the outer side of the first electric push rod. A roller is rotatably connected to the inner side of the limiting housing. A rotating belt is rotatably connected to the outer side of the roller. When the conveyor moves the pipe, it rubs against the rotating belt. The rotating belt rotates outside the roller, thereby facilitating the movement of the pipe on the surface of the component and avoiding affecting the movement effect of the pipe.

[0007] Preferably, the positioning device includes a positioning housing, the outer side of which is fixedly connected to the outer side of the protective plate. A sliding groove is formed on one side of the outer side of the positioning housing, and a sliding block is slidably connected to the outer side of the sliding groove. When the pipe moves to the opening of the positioning housing by the conveyor, the sliding block moves towards the center of the opening inside the sliding groove, thereby fixing the object and facilitating subsequent cutting.

[0008] Preferably, a sliding rod is slidably connected to the outer side of the sliding block, and a spring strip is sleeved on the outer side of the sliding rod. When the sliding block is pressed against the pipe, the silicone block adheres to the pipe surface. At the same time, the silicone block is subjected to the reaction force of the pipe, causing the sliding rod to drive the spring strip to compress, thereby achieving a shock absorption and buffering effect, reducing the compression pressure, reducing rigid collisions between the component and the pipe, avoiding damage to the pipe during clamping, thus protecting the pipe, reducing the vibration amplitude during pipe transportation, improving pipe stability, and increasing clamping efficiency. A clamping plate is fixedly connected to one side of the outer side of the sliding rod, and a silicone block is fixedly connected to the outer side of the clamping plate away from the sliding rod. The silicone block is made of silicone, which has good wear resistance and cushioning effect, reducing wear between the component and the object, thereby extending the service life of the component. The outer side of the silicone block has a surface cut, and by creating a surface cut and groove, the texture of the component is increased, thereby increasing the friction with the pipe, further improving the fixing effect, and providing a certain anti-slip effect. A damping device is fixedly connected to the outer side of the sliding block away from the silicone block.

[0009] Preferably, the damping device includes a damping housing, with a clamping block inserted into the outer side of the damping housing. A rotating shaft is rotatably connected to one side of the clamping block. When the sliding rod is subjected to pressure and compresses the spring strip, it continues to generate kinetic energy. When the compression pressure decreases, the spring strip causes the sliding rod to rebound quickly, which can easily increase mechanical damage to the component and affect its service life. By using friction between the sliding rod and the friction belt, the sliding speed of the component is slowed down, the wear of the component is reduced, and the service life of the component is extended. A friction belt is rotatably connected to the outer side of the rotating shaft. When the friction belt is subjected to friction, it rotates outside the rotating shaft to avoid affecting the sliding effect of the component.

[0010] Preferably, the processing device includes a processing support, with a second electric push rod fixedly connected between opposite surfaces of the processing support. The second electric push rod controls the extension and retraction of the processing support, driving the components to move during the extension and retraction process, thereby adjusting the component angle to meet different operational needs and reducing component obstruction to prevent affecting equipment operation. A processing housing is fixedly connected to the outer side of the processing support away from the circular saw, and a collection pipe is fixedly connected to the outer side of the processing housing. A funnel plate is fixedly connected to the inner wall of the processing housing near the collection pipe. The funnel plate guides the flow of debris and reduces backflow of debris. During the process of absorbing debris, it also absorbs the gas generated during cutting. A first fan is fixedly connected to the outer side of the processing housing away from the funnel plate. The first fan generates airflow to draw debris from the pipe through the collection pipe into the processing housing for temporary storage. A filter mechanism is inserted and connected to the outer side of the first fan, and then the gas is discharged from the filter mechanism to the outside, thereby filtering the gas and preventing the gas from harming the human body. A rotating mechanism is fixedly connected to one side of the inner wall of the collection pipe, and a cleaning mechanism is fixedly connected to the outer side of the processing housing away from the processing support.

[0011] Preferably, the rotating mechanism includes a receiving shaft, a rotating column rotatably connected to the outer side of the receiving shaft, a square paddle fixedly connected to one side of the rotating column, a rotating bracket fixedly connected to the outer side of the rotating column away from the square paddle, and a scraper fixedly connected to one side of the rotating bracket. Wind power drives the square paddle to rotate, and the rotating bracket controls the scraper to rub against the inner wall of the equipment, thereby cleaning impurities from the inner wall, reducing debris adhesion, preventing blockage of components, preventing interference with gas flow, and maintaining normal equipment operation.

[0012] Preferably, the filtration mechanism includes a filter housing, with a locking block fixedly connected to the inner wall of the filter housing. A filter element is inserted into the inner side of the locking block. The gas generated during cutting enters the filter housing with the airflow, allowing the gas to contact the filter element, thereby achieving the function of filtering waste gas, preventing the gas from being directly discharged, preventing the gas from affecting the human body and the environment, thus reducing safety hazards and avoiding pollution to the external environment. A connecting pipe is fixedly connected to the side of the filter housing away from the treatment housing, and a flexible hose can be connected to one side of the connecting pipe to discharge the treated gas to the outside.

[0013] Preferably, the cleaning mechanism includes a cleaning base, with a second fan fixedly connected to one side of the cleaning base. The second fan generates airflow, which draws in debris through the feed pipe and cleans impurities inside the processing housing. This reduces impurity accumulation, prevents excessive accumulation from affecting gas flow, and avoids the equipment from sucking in debris, thus reducing the amount of debris stored inside the equipment through regular cleaning and maintaining continuous operation. A cleaning housing is fixedly connected to the side of the cleaning base away from the second fan. A feed pipe is fixedly connected to the outer side of the cleaning housing. Multiple feed pipes are provided to increase the feed flow rate, thereby improving the cleaning efficiency and preventing pipe blockage. A connecting column is fixedly connected to the inner wall of the cleaning housing. A support shaft is fixedly connected to the outer side of the connecting column. A wall scraping mechanism is rotatably connected to the outer side of the support shaft near the feed pipe.

[0014] Preferably, the scraping mechanism includes a scraping housing, with an arc-shaped paddle fixedly connected to the middle of the outer surface of the scraping housing. An airflow is generated by a second fan, causing the airflow to impact the arc-shaped paddle, thereby driving the component to rotate. Scraping brackets are fixedly connected to both ends of the outer surface of the scraping housing, and friction columns are rotatably connected between the opposite surfaces of the scraping brackets. The rotation of the arc-shaped paddle drives the scraping brackets to rotate, causing the scraping brackets to control the friction columns to scrape against the inner wall of the feed pipe, thereby cleaning impurities from the inner wall of the pipe, preventing impurities from adhering to the pipe surface, preventing blockage, and avoiding affecting the subsequent feeding effect.

[0015] This invention provides a steam pipe cutting machine with positioning function. It has the following beneficial effects:

[0016] I. This steam pipe cutting machine with positioning function, through its cutting device design, allows the pipe to enter from one side of the conveyor and move towards the circular saw, thus achieving automatic material conveying, reducing manual support and movement, and improving work efficiency. During the conveying process, a limiting mechanism contacts the pipe surface to guide the pipe's movement, reducing pipe swaying space and preventing excessive shaking during conveying, which could affect subsequent cutting results. A positioning device clamps the pipe to fix it, thereby improving cutting quality, preventing shaking during cutting, reducing pipe vibration and component collisions, reducing component wear, and extending component lifespan. A servo motor controls the lead screw to rise and fall inside the machine body, thereby controlling the height of the circular saw to meet subsequent cutting needs. During the circular saw cutting process, debris and gas are easily generated. A processing device cleans and collects the debris and filters the gas, thereby optimizing the working environment and reducing safety hazards.

[0017] II. This steam pipe cutting machine with positioning function uses a limiting mechanism design. An electric push rod controls the limiting shell to approach the pipe, thereby achieving a fitting effect. By fitting the pipe to the conveyor, the machine restricts the pipe's movement space inside the conveyor. This prevents the pipe from colliding with components and bending, which would affect the cutting effect. It also reduces the pipe's vibration amplitude, making it easier to position and fix the components later, reducing the difficulty of subsequent fixing. When the conveyor moves the pipe, it rubs against the rotating belt. The rotating belt rotates on the outside of the roller, which facilitates the movement of the pipe on the component surface and avoids affecting the pipe movement effect.

[0018] III. This steam pipe cutting machine with positioning function, through its positioning device design, allows the pipe to move towards the center of the positioning housing via a sliding block inside the sliding groove as the pipe is conveyed. This fixes the pipe, facilitating subsequent cutting. As the sliding block engages with the pipe, a silicone block adheres to the pipe surface. Simultaneously, the silicone block experiences a reaction force from the pipe, causing the sliding rod to compress the spring strip, thus providing shock absorption and cushioning. This reduces pressure and rigid collisions between the component and the pipe, preventing damage during clamping and protecting the pipe. It also reduces vibration amplitude during pipe transport, improves pipe stability, and increases clamping efficiency. The silicone block is made of silicone, which has excellent wear resistance and cushioning properties, reducing wear between the component and the object, thereby extending the component's lifespan. The cutting of the block surface and the creation of grooves increase the texture of the component, enhancing friction with the pipe and further improving the fixing effect, while also providing a certain degree of anti-slip effect.

[0019] IV. This steam pipe cutting machine with positioning function, through its processing device design, uses a second electric push rod to control the extension and retraction of the processing support. During the extension and retraction process, it moves the components to adjust their angles, thereby meeting different operational needs and reducing component obstruction to prevent affecting equipment operation. The first fan generates airflow to draw pipe debris from the collection pipe into the processing housing for temporary storage. The funnel plate guides the flow of debris and reduces backflow. During the process of absorbing debris, the machine also absorbs the gas generated during cutting and then discharges the gas through the filtration mechanism, thus filtering the gas and preventing it from harming the human body.

[0020] V. This steam pipe cutting machine with positioning function, through its cleaning mechanism design, uses a second fan to generate airflow, which draws in debris through the feed pipe and cleans impurities inside the processing shell. This reduces debris accumulation, prevents excessive accumulation from affecting gas flow, and avoids the equipment sucking in debris to improve cleaning efficiency. Regular cleaning reduces the amount of debris stored inside the equipment, thus maintaining continuous operation. Multiple feed pipes are provided to increase the feed flow rate, thereby improving cleaning efficiency and preventing pipe blockage. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] First embodiment, such as Figures 1 to 4 As shown, the present invention provides a technical solution: a steam pipe cutting machine with positioning function, including a cutting device 1, a positioning device 2 fixedly connected to the outside of the cutting device 1, and a processing device 3 fixedly connected to the side of the cutting device 1 away from the positioning device 2.

[0034] The cutting device 1 includes a cutting base 11, a cutting frame 12 fixedly connected to one side of the top of the cutting base 11, a body 13 fixedly connected to the top of the cutting frame 12, a lead screw 15 rotatably connected to the inner side of the body 13, a servo motor 14 fixedly connected to the outer side of the body 13, a circular saw 16 fixedly connected to one side of the lead screw 15, a conveyor 17 fixedly connected to the outer side of the cutting base 11 away from the cutting frame 12, a protective plate 18 fixedly connected to the top of the conveyor 17, and limiting mechanisms 19 fixedly connected to both sides of the outer side of the protective plate 18. The pipe enters from one side of the conveyor 17 and is transported to the circular saw 16 via the conveyor 17, thereby achieving automatic material transport, reducing manual support and movement, and improving work efficiency. During the transport process, the limiting mechanism 19 contacts the pipe surface to guide the pipe's movement, reduce the pipe's sway space, and prevent excessive shaking during transport, thus preventing it from affecting the subsequent cutting effect. The positioning device 2 clamps the pipe to fix it, thereby improving the cutting quality, preventing shaking during the cutting process, reducing pipe vibration and component collisions, reducing component wear, and extending the service life of the components. The servo motor 14 controls the lead screw 15 to rise and fall inside the machine body 13, thereby controlling the height of the circular saw 16 to meet subsequent cutting requirements. During the cutting process of the circular saw 16, debris and gas are easily generated. The processing device 3 cleans and collects the debris and filters the gas, thereby optimizing the working environment and reducing safety hazards.

[0035] The limiting mechanism 19 includes a limiting frame 191. A first electric push rod 192 is fixedly connected to the outer side of the limiting frame 191. A limiting housing 193 is fixedly connected to one side of the outer side of the first electric push rod 192. A roller 194 is rotatably connected to the inner side of the limiting housing 193. A rotating belt 195 is rotatably connected to the outer side of the roller 194. The first electric push rod 192 controls the limiting housing 193 to move closer to the pipe, thereby achieving the function of conforming to the pipe. By conforming to the pipe, the movement space of the pipe inside the conveyor 17 is limited. On the one hand, this avoids collision between the pipe and the component, preventing the pipe from bending and affecting the cutting effect. On the other hand, it reduces the vibration amplitude of the pipe, making it easier to position and fix the component later, reducing the difficulty of subsequent fixing. When the conveyor 17 moves the pipe, it rubs against the rotating belt 195. The rotating belt 195 rotates outside the roller 194, thereby facilitating the movement of the pipe on the surface of the component and avoiding affecting the movement effect of the pipe.

[0036] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 5 to 6As shown, the positioning device 2 includes a positioning housing 21, the outer side of which is fixedly connected to the outer side of the protective plate 18. A sliding groove 22 is provided on one side of the outer side of the positioning housing 21, and a sliding block 23 is slidably connected to the outer side of the sliding groove 22. When the pipe moves to the opening of the positioning housing 21 by the conveyor 17, the sliding block 23 moves towards the center of the opening inside the sliding groove 22, thereby fixing the object. Fixing the pipe facilitates subsequent cutting.

[0037] A sliding rod 24 is slidably connected to the outside of the sliding block 23. A spring strip 25 is sleeved on the outside of the sliding rod 24. A clamping plate 26 is fixedly connected to one side of the outside of the sliding rod 24. A silicone block 27 is fixedly connected to the outside of the clamping plate 26 away from the sliding rod 24. A block surface cutout 28 is opened on the outside of the silicone block 27. A slowing device 29 is fixedly connected to the outside of the sliding block 23 away from the silicone block 27. As the sliding block 23 adheres to the pipe, the silicone block 27 adheres to the pipe surface. Simultaneously, the silicone block 27 is subjected to the reaction force of the pipe, causing the sliding rod 24 to drive the spring strip 25 to compress, thereby achieving a shock absorption and buffering effect, reducing the compression pressure, reducing rigid collisions between the component and the pipe, and avoiding damage to the pipe during clamping. This provides protection for the pipe, reduces the vibration amplitude during pipe transportation, improves pipe stability and speed, and increases clamping efficiency. The silicone block 27 is made of silicone, which has good wear resistance and cushioning effect, reducing wear between the component and the object, thereby extending the service life of the component. By opening the block surface cuts 28 and grooves to increase the texture of the component, the friction with the pipe is increased, further improving the fixing effect and providing a certain anti-slip effect.

[0038] The damping device 29 includes a damping housing 291, with a clamping block 292 inserted into the outer side of the damping housing 291. A rotating shaft 293 is rotatably connected to one side of the clamping block 292, and a friction belt 294 is rotatably connected to the outer side of the rotating shaft 293. When the sliding rod 24 is subjected to pressure and compresses the spring strip 25, it continues to generate kinetic energy. When the compressive pressure decreases, the spring strip 25 causes the sliding rod 24 to rebound quickly, which can easily increase mechanical damage to the component and affect its service life. By frictionally adapting the sliding rod 24 and the friction belt 294, the sliding speed of the component is slowed down, the wear of the component is reduced, and the service life of the component is extended. When the friction belt 294 is subjected to friction, it rotates outside the rotating shaft 293 to avoid affecting the sliding effect of the component.

[0039] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 7 to 10As shown, the processing device 3 includes a processing bracket 31, a second electric push rod 32 fixedly connected between opposite surfaces of the processing bracket 31, a processing housing 33 fixedly connected to the outer side of the processing bracket 31 away from the circular saw 16, a collection pipe 34 fixedly connected to the outer side of the processing housing 33, a funnel plate 35 fixedly connected to the inner wall of the processing housing 33 near the collection pipe 34, a first fan 36 fixedly connected to the outer side of the processing housing 33 away from the funnel plate 35, a filter mechanism 37 inserted into the outer side of the first fan 36, a rotating mechanism 39 fixedly connected to the inner wall of the collection pipe 34, and a cleaning mechanism 38 fixedly connected to the outer side of the processing housing 33 away from the processing bracket 31. The extension and retraction of the processing bracket 31 is controlled by the second electric push rod 32. During the extension and retraction, the components move to adjust their angles, thereby meeting different operational needs and reducing component obstruction to prevent affecting equipment operation. The first fan 36 generates airflow to draw pipe debris from the collection pipe 34 into the processing housing 33 for temporary storage. The funnel plate 35 guides the flow of debris and reduces backflow. During the process of absorbing debris, the gas generated during cutting is absorbed and then discharged from the filtration mechanism 37 to the outside, thereby filtering the gas and preventing it from harming the human body.

[0040] The rotating mechanism 39 includes a receiving shaft 391, a rotating column 392 rotatably connected to the outer side of the receiving shaft 391, a square paddle 393 fixedly connected to one side of the outer side of the rotating column 392, a rotating bracket 394 fixedly connected to the outer side of the rotating column 392 away from the square paddle 393, and a scraper 395 fixedly connected to one side of the outer side of the rotating bracket 394. Wind power drives the square paddle 393 to rotate, and the rotating bracket 394 controls the scraper 395 to rub against the inner wall of the equipment, thereby cleaning impurities on the inner wall of the equipment, reducing debris adhesion, preventing blockage of components, preventing interference with gas flow, and maintaining normal operation of the equipment.

[0041] The filtration mechanism 37 includes a filter housing 371. A locking block 372 is fixedly connected to the inner wall of the filter housing 371, and a filter element 373 is inserted into the inner side of the locking block 372. A connecting pipe 374 is fixedly connected to the outer side of the filter housing 371 away from the processing housing 33. The gas generated during cutting enters the interior of the filter housing 371 with the airflow, allowing the gas to come into contact with the filter element 373, thereby achieving the function of filtering the waste gas, preventing the gas from being directly discharged, preventing the gas from affecting human health and the environment, thus reducing safety hazards and avoiding pollution to the external environment. A flexible hose can be connected to one side of the connecting pipe 374 to discharge the treated gas to the outside.

[0042] The cleaning mechanism 38 includes a cleaning base 381. A second fan 382 is fixedly connected to one side of the cleaning base 381. A cleaning housing 383 is fixedly connected to the side of the cleaning base 381 away from the second fan 382. A feed pipe 385 is fixedly connected to the outer side of the cleaning housing 383. A connecting column 387 is fixedly connected to the inner wall of the cleaning housing 383. A support shaft 384 is fixedly connected to the outer side of the connecting column 387. A scraping mechanism 386 is rotatably connected to the outer side of the support shaft 384 near the feed pipe 385. The second fan 382 generates airflow, which draws in debris through the feed pipe 385, cleaning impurities inside the processing housing 383. This reduces impurity accumulation, prevents excessive accumulation from affecting airflow, and avoids the equipment sucking in debris, thus reducing the cleaning effect. Regular cleaning reduces the amount of debris stored inside the equipment, maintaining continuous operation. Multiple feed pipes 385 are provided to increase the feed flow rate, improve cleaning efficiency, and prevent pipe blockage.

[0043] The wall scraping mechanism 386 includes a wall scraping housing 3861, an arc-shaped paddle 3862 fixedly connected to the middle of the outer side of the wall scraping housing 3861, and wall scraping supports 3863 fixedly connected to both ends of the outer side of the wall scraping housing 3861. Friction columns 3864 are rotatably connected between the opposite surfaces of the wall scraping supports 3863. Airflow is generated by a second fan 382, ​​causing the airflow to impact the arc-shaped paddle 3862, thereby driving the component to rotate. The rotation of the arc-shaped paddle 3862 drives the wall scraping supports 3863 to rotate, causing the wall scraping supports 3863 to control the friction columns 3864 to scrape against the inner wall of the feed pipe 385. This cleans impurities from the inner wall of the pipe, preventing impurities from adhering to the pipe surface, preventing blockages, and avoiding affecting subsequent feeding.

[0044] In use, the pipe enters from one side of the conveyor 17 and moves towards the circular saw 16 via the conveyor 17, thus achieving automatic material conveying, reducing manual support and movement, and improving work efficiency. During the conveying process, the limiting mechanism 19 contacts the pipe surface to guide the pipe's movement, reduce pipe swaying space, and prevent excessive shaking during conveying, thus preventing it from affecting the subsequent cutting effect. During the pipe conveying process, it contacts the positioning device 2, which fixes the pipe, thus positioning the pipe and adapting it to the circular saw 16. The circular saw 16 then cuts the fixed pipe to meet work requirements. Furthermore, the positioning device 2 also serves as a shock absorber, reducing extrusion pressure and minimizing the impact between parts and the pipe. The rigid collision between pipes prevents damage during clamping, thus protecting the pipes and reducing vibration amplitude during pipe transport, improving pipe stability and clamping efficiency. During pipe cutting by the circular saw 16, debris and gas are easily generated. Debris accumulation on the equipment surface increases wear between components, affecting the equipment's lifespan. The processing device 3 draws pipe debris from the collection pipe 34 into the processing housing 33 for temporary storage. The funnel plate 35 guides the debris flow and reduces backflow. During debris absorption, the gas generated during cutting is also absorbed and then discharged through the filtration mechanism 37, thus filtering the gas and preventing harm to personnel.
