Description

Technical Field

[0001] This invention relates to the field of ductile iron pipe manufacturing technology, specifically an automatic adjustment system for cement lining of ductile iron pipes. Background Technology

[0002] Ductile iron pipes are pipes made by centrifugally casting molten iron of grade 18 or higher with the addition of spheroidizing agents using a centrifugal ductile iron casting machine at high speed. They are also known as ductile iron pipes or ductile cast iron pipes. They are mainly used for the transportation of tap water and are an ideal material for tap water pipelines. Cast iron steel pipes are essentially ductile iron pipes. Because ductile iron pipes have the essence of iron and the performance of steel, the graphite in ductile iron pipes exists in a spherical form. Generally, the size of the graphite is grade 6-7. In terms of quality, the spheroidization grade of cast iron pipes is required to be controlled at grade 1-3. Therefore, the mechanical properties of the material itself are well improved, possessing the essence of iron and the performance of steel.

[0003] An investigation revealed that a Chinese invention patent (publication number: CN103465346B) discloses a cement lining device for centrifugal ductile iron pipes. The device includes a frame, a pressure roller assembly, a first drive roller assembly, a second drive roller assembly, a first driven roller assembly, a second driven roller assembly, a stop roller, and a pressure roller assembly. A drive motor is mounted on one side of the second drive roller assembly on the frame. The driving roller of the second drive roller assembly is connected to the drive motor via a second transmission shaft. The driving rollers of the first and second drive roller assemblies are connected via a first transmission shaft. The stop roller has axially evenly distributed elongated grooves on its outer circumferential surface that contacts the end of the ductile iron pipe. This invention ensures uniform and stable rotation speed of the centrifugal ductile iron pipe, forming a uniform and dense cement layer on the inner wall of the pipe, effectively improving the quality of the cement lining and increasing production efficiency.

[0004] Although the aforementioned patent ensures uniform and stable rotation speed of the ductile iron pipe through the design of the drive motor and the second drive roller assembly, forming a uniform cement lining layer and reducing the scrap rate, and the axially distributed elongated grooves on the outer circumference of the guide roller generate pulse vibrations on the rotating ductile iron pipe, which can compact the cement lining layer and effectively improve product quality, in the overall process of ductile iron pipe production, after the cast iron pipe is produced, it undergoes a series of processes, one of which is cement lining. A certain amount of cement is applied to the inside of the bare pipe, and then a high-speed rotation process is carried out, using centrifugal force to spread the cement on the inner wall of the bare pipe. In reality, because the pipe is long, the operator cannot detect the uniformity of the cement coating on the inner wall in time, and cannot adjust the speed of the trolley to control the amount of cement. This can easily lead to uneven coating on the inner wall in subsequent processes, resulting in a large number of scrap pipes and wasting ductile iron pipes.

[0005] Therefore, the present invention provides an automatic adjustment system for cement lining of ductile iron pipes to solve the above problems. Summary of the Invention

The storage box contains cement. The upper surface of the storage box is fixedly connected to the feed pipe. The lower surface of the storage box is fixedly connected to the connecting frame. The lower surface of the connecting frame is equipped with movable wheels in a rectangular array.

[0011] As a preferred technical solution of this application, the feeding mechanism further includes a DC motor fixedly connected to the middle of the upper surface of the connecting frame, and a stirring rod rotatably connected to the inside of the storage tank is installed at the output end of the DC motor.

[0017] (III) Beneficial Effects The feeding mechanism delivers cement into the ductile iron pipe body, and the supporting mechanism enables the automatic rotation of the ductile iron pipe body. This allows the cement to flow inside the ductile iron pipe body and adhere to its inner wall. During the cement lining process, an industrial high-definition AI recognition camera monitors the cement flow rate in real time, and the PLC control cabinet controls the cement output and the rotation speed of the moving wheels, adjusting the movement speed of the storage tank to match the cement output with the movement speed of the storage tank. This ensures a more uniform amount of cement flowing onto the inner wall of the ductile iron pipe body at each position reached by the feeding pipe. Simultaneously, the real-time view of the inside of the ductile iron pipe body is displayed on the client side. This not only reduces labor intensity but also improves the degree of automation and the timeliness of inspection. Based on the cooperation of adjustment mechanisms and other structures, during the rotation of the ductile iron pipe body, the cement material inside the ductile iron pipe body is scraped and coated by the arc-shaped scraper, so that the cement material adheres more evenly to the inner wall of the ductile iron pipe body, avoiding the waste of ductile iron pipe body material due to uneven cement lining coating. Furthermore, the cooperation of threaded rods and servo motors enables fine adjustment of the position of the arc-shaped scraper, thereby adjusting the contact depth between the arc-shaped scraper and the cement material, adjusting the thickness of cement lining adhesion, and achieving different effects of cement lining coating on ductile iron pipes. Based on the cooperation between the cleaning mechanism and the feeding mechanism, the rotating screw drives the rotating disk and the push rod to rotate during the rotation of the screw. This causes the push rod to drive the extension rod to reciprocate, which in turn causes the drive rod to drive the cleaning plate to slide on one side of the industrial high-definition AI recognition camera. This cleans the industrial high-definition AI recognition camera and prevents the dust and cement splashes generated during the cement lining construction from affecting the image captured by the industrial high-definition AI recognition camera, thereby affecting the real-time monitoring of cement output.

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.

[0021] This invention provides an automatic adjustment system for cement lining of ductile iron pipes, referring to... Figures 1-8 As shown, three embodiments are provided: Example 1: The automatic adjustment system for cement lining of ductile iron pipe includes a support mechanism 1 and a PLC control cabinet 2 installed on the surface of the support mechanism 1. An adjustment mechanism 3 is installed on the surface of the support mechanism 1, and a feeding mechanism 4 is installed on the surface of the adjustment mechanism 3. The adjustment mechanism 3 includes a ductile iron pipe body 301 rotatably connected to the surface of the support mechanism 1 in a path array. A feed pipe 302 is inserted into the inside of one of the ductile iron pipe bodies 301. A rotating rod 303 is rotatably connected to one end of the feed pipe 302. A support frame 304 is fixedly connected to the surface of the feed pipe 302. An industrial high-definition AI recognition camera 305 corresponding to the ductile iron pipe body 301 is fixedly connected to the surface of the support frame 304. A cleaning mechanism 5 is installed on one side of the industrial high-definition AI recognition camera 305. Among them, the feed pipe 302 is used to transport cement material into the interior of the ductile iron pipe body 301; Among them, the support frame 304 is used to install the industrial high-definition AI recognition camera 305; Among them, the rotating rod 303 is used to connect and drive the rotating disk 505 to rotate; Among them, the industrial high-definition AI recognition camera 305 is used to photograph, monitor and transmit the cement lining construction process and cement lining adhesion of the ductile iron pipe body 301. The feeding mechanism 4 includes a screw rod 401 rotatably connected to the feed pipe 302 and corresponding to the feed pipe 302. One end of the screw rod 401 is fixedly connected to a connecting rod 402 rotatably connected to the feed pipe 302. One end of the connecting rod 402 is fixedly connected to a drive motor 403. Among them, the screw rod 401 is used to drive the cement material to move into the ductile iron pipe body 301; The connecting rod 402 and the drive motor 403 are used to drive the screw rod 401 to rotate in the feed pipe 302; The feeding mechanism 4 also includes a storage box 404 fixedly connected to the surface of the drive motor 403 and connected to the feed pipe 302. Cement is provided inside the storage box 404. The upper surface of the storage box 404 is fixedly connected to the feed pipe, and the lower surface of the storage box 404 is fixedly connected to the connecting frame 405. The lower surface of the connecting frame 405 is equipped with movable wheels in a rectangular array. Storage box 404 is used to store cement materials; The feed pipe is used to add cement to the storage tank 404; The connecting frame 405 is used to support the storage box 404; Among them, the movable wheels are used to drive the connecting frame 405, the storage box 404 and the feed pipe 302 to move in the ductile iron pipe body 301; Specifically, the feed pipe 302 is inserted into the ductile iron pipe body 301, and the drive motor 403 is started, so that its output end drives the connecting rod 402 to rotate, thereby causing the screw rod 401 to rotate, and the cement material in the storage box 404 is transported to the ductile iron pipe body 301 through the feed pipe 302, so that the cement material can adhere to the inner wall of the ductile iron pipe body 301, thereby achieving the effect of adding cement lining inside the ductile iron pipe body 301; Simultaneously, the cement output of the feed pipe 302 is monitored in real time by setting up an industrial high-definition AI recognition camera 305, and the cement lining adhering to the inner wall of the ductile iron pipe body 301 is identified. According to the cement output, the speed of the moving wheels is controlled by the PLC control cabinet 2 to adjust the moving speed of the connecting frame 405, the storage box 404 and the feed pipe 302, so that the cement output is matched with the moving speed of the storage box 404. This makes the amount of cement flowing to the inner wall of the ductile iron pipe body 301 more uniform at each position of the feed pipe 302. At the same time, the real-time scene inside the ductile iron pipe body 301 is displayed on the client side, which not only reduces labor intensity, but also improves the degree of automation and the timeliness of detection.

[0022] In Example 2, based on Example 1, the adjustment mechanism 3 further includes a mounting bracket 306 fixedly connected to both sides of the support frame 304. A threaded rod 307 is rotatably connected inside the mounting bracket 306 via a bearing seat. One end of the threaded rod 307 passes through the mounting bracket 306 and is fixedly connected to a servo motor 308 fixedly connected to the mounting bracket 306. A moving block 309 is threadedly connected to the surface of the threaded rod 307. An arc-shaped scraper 310 corresponding to the ductile iron pipe body 301 is fixedly connected to one side of the moving block 309. The mounting bracket 306 is used to support the threaded rod 307 and the arc-shaped scraper 310. The threaded rod 307 and the servo motor 308 work together to drive the moving block 309 and the arc-shaped scraper 310 to adjust their positions, thereby achieving fine-tuning of the position of the arc-shaped scraper 310. Among them, the arc-shaped scraper 310 is used to scrape the cement material that enters the ductile iron pipe body 301, so that the cement material is more evenly attached to the inner wall of the ductile iron pipe body 301. Specifically, during the rotation of the ductile iron pipe body 301, the cement material inside the ductile iron pipe body 301 is scraped and coated based on the setting of the arc-shaped scraper 310, so that the cement material adheres more evenly to the inner wall of the ductile iron pipe body 301, avoiding the waste of ductile iron pipe body 301 material due to uneven cement lining coating. At the same time, according to the requirements of cement lining thickness, the servo motor 308 can be started, so that its output end drives the threaded rod 307 to rotate, thereby adjusting the position of the moving block 309 and the arc scraper 310, realizing the fine adjustment of the position of the arc scraper 310, thereby adjusting the depth of contact between the arc scraper 310 and the cement material, adjusting the thickness of cement lining adhesion, and achieving different effects of cement lining coating on the ductile iron pipe body 301. The feeding mechanism 4 also includes a DC motor 406 fixedly connected to the middle of the upper surface of the connecting frame 405. The output end of the DC motor 406 is equipped with a stirring rod 407 rotatably connected to the inside of the storage tank 404. The connecting rod 402 is rotatably connected to the inside of the storage tank 404. The moving wheel and the drive motor 403 are connected to the PLC control cabinet 2. Among them, DC motor 406 is used to drive stirring rod 407 to rotate; The stirring rod 407 is used to stir the cement material inside the storage tank 404; Specifically, when the cement material is transported to the storage tank 404, the DC motor 406 is started simultaneously, so that its output end drives the stirring rod 407 to rotate inside the storage tank 404, stirring the cement material inside, avoiding the cement material from standing for too long and causing material separation, which would affect the uniformity of the cement material, and also preventing the cement material from solidifying.

[0023] In Example 3, based on Examples 1 and 2, the cleaning mechanism 5 further includes a cleaning plate 501 attached to one side of the industrial high-definition AI recognition camera 305. A drive rod 502 rotatably connected to the surface of the cleaning plate 501 is fixedly connected to the inside of the ductile iron pipe body 301. A stabilizing plate fixedly connected to the support frame 304 is rotatably sleeved on the surface of the drive rod 502. Among them, the cleaning board 501 is used to clean the industrial high-definition AI recognition camera 305; Among them, the drive rod 502 and the stabilizing plate are used to drive the cleaning plate 501 to reciprocate and maintain the stability of the cleaning plate 501 during the reciprocating motion. The cleaning mechanism 5 also includes a torsion spring 503 with its two ends fixedly connected to the drive rod 502 and the surface of the stabilizing plate, respectively. An extension rod 504 is fixedly connected to the surface of the drive rod 502. The extension rod 504 is used to drive the cleaning plate 501 to move back and forth on one side of the industrial high-definition AI recognition camera 305. Among them, the torsion spring 503 is used for the automatic reset of the drive rod 502 and the cleaning plate 501; The extension rod 504 is used to extend the drive rod 502, so that the drive rod 502 can move by the power of the push rod 506; The cleaning mechanism 5 also includes a rotating disk 505 fixedly connected to the surface of the rotating rod 303. The surface of the rotating disk 505 is fixedly connected to a push rod 506 in a ring array. The push rod 506 corresponds to the extension rod 504. The rotating rod 303 is fixedly connected to the spiral rod 401. Among them, the rotating disk 505 is used to drive the push rod 506 to rotate inside the ductile iron pipe body 301; Among them, the push rod 506 is used to drive the extension rod 504 to reciprocate; Specifically, during the rotation of the screw rod 401, the rotating rod 303 and the rotating disk 505 are driven to rotate within the ductile iron pipe body 301, causing the push rod 506 to rotate synchronously. This causes the push rod 506 to contact the extension rod 504. The force applied by the push rod 506 causes the extension rod 504 to rotate, thereby driving the drive rod 502 and the cleaning plate 501 to reciprocate on one side of the industrial high-definition AI recognition camera 305. This cleans one side of the industrial high-definition AI recognition camera 305, preventing dust and splashed cement from affecting the image capture of the industrial high-definition AI recognition camera 305 during cement lining construction, thus affecting the real-time monitoring of cement output. Furthermore, through the setting of the torsion spring 503, after the push rod 506 disengages from the extension rod 504, the drive rod 502 and the extension rod 504 are automatically reset based on the elastic force of the torsion spring 503, which facilitates the next push rod 506 to drive the extension rod 504 to rotate, thereby facilitating continuous cleaning of the industrial high-definition AI recognition camera 305; The support mechanism 1 includes a support frame 101. The surface of the support frame 101 is rotatably connected to a rotating roller 102 in a path array. Both ends of the rotating roller 102 are fixedly connected to a towing wheel body 103 that fits against the ductile iron pipe body 301. One end of the rotating roller 102 is connected to a linkage rod 104 via a belt drive. One end of the linkage rod 104 is fixedly connected to an existing motor. Among them, the support frame 101 is used to support the ductile iron pipe body 301 and the support mechanism 1; The rotating roller 102 is used to drive the main body of the tugboat 103; Among them, the towing wheel body 103 is used to drive the ductile iron pipe body 301 to rotate; The linkage 104 and the motor are used to drive the rotating roller 102 to rotate. Specifically, the ductile iron pipe body 301 is placed on the inner arc surface of the trolley body 103. After the feed pipe 302 is inserted into the ductile iron pipe body 301, the motor is started, and its output end drives the linkage rod 104 to rotate. Through the belt setting, the rotating roller 102 rotates, thereby driving the trolley body 103 to rotate, so that the ductile iron pipe body 301 rotates accordingly. This allows the cement material entering the ductile iron pipe body 301 to be evenly adhered to the inner wall of the ductile iron pipe body 301. Both sides of the surface of the support frame 101 are fixedly connected with guide plates 6 corresponding to the ductile iron pipe body 301. The PLC control cabinet 2 is fixedly connected to the upper surface of the support frame 101. The connecting frame 405 and the moving wheels are corresponding to the support frame 101. Based on the settings of PLC control cabinet 2, the electronic components in the automatic adjustment system for cement lining of ductile iron pipe are controlled.
