[0002] Steel molds for pipe piles are the core equipment for producing prestressed concrete pipe piles. The cleanliness of their inner surfaces directly affects the demolding effect, appearance quality, and production efficiency of the pipe piles. Therefore, daily cleaning and periodic deep cleaning are required during the pipe pile production cycle. When daily cleaning cannot completely remove stubborn deposits and mold release agent buildup, deep cleaning is required. Currently, mechanical cleaning or chemical cleaning can be selected.

The other side of the chemical cleaning tank is fixedly installed in the water collection tank.

[0019] A method for cleaning steel molds for pipe piles, applied to the aforementioned cleaning device for steel molds for pipe piles, includes the following steps:

[0020] S101. Preliminary pre-cleaning: After the production process is completed, confirm that the pipe piles inside the mold have been completely lifted out, receive the mold, and conduct a preliminary visual inspection. While the mold is still warm, use tools to quickly tap and peel off large pieces of loose concrete residue from the inner wall of the mold, the joint seam, and the flanges at both ends.

[0021] S102. Chemical Immersion Cleaning: In advance, use special slow-release industrial hydrochloric acid in the chemical cleaning tank, dilute the concentrated solution with water according to the ratio, and use an overhead crane to steadily and slowly lift the mold into the support frame in the chemical cleaning tank. The mold is then completely immersed in the acid solution through the transfer structure. The concentration is controlled between 5% and 15%, the reaction temperature is controlled between 20 and 40°C, and the soaking time is 4-8 hours. The generation of bubbles in the tank can be used as an auxiliary judgment.

[0022] S103. Transfer after soaking: Use the transfer structure to slowly lift the mold and transfer the support frame and the mold together to the area of ​​the electric chuck. During the transfer, the mold is placed on the support frame to drain, allowing most of the acid to flow back into the tank.

[0023] S104. Moving and cleaning mold: After being transferred to the area of ​​the electric chuck, the photoelectric sensor transmits a signal to the electric telescopic rod, which in turn drives the electric chuck to clamp the mold. After clamping, the moving device drives the pipe pile steel mold in the electric chuck to move along the long hole and pass through the flushing component and cleaning mechanism in sequence. It flips in the flushing component area until it stops in the cleaning mechanism.

[0024] S105, Tilting and rinsing the mold: In the rinsing component area, the high-pressure nozzle of the rinsing component is used at a pressure of 80-150 Bar, the rinsing time is 5-15 minutes, and the flow rate is maintained at 20-25 L / min. Since the mold is driven to rotate by the moving device during the movement, the inside and outside of the mold and the inner wall can be thoroughly rinsed during the rinsing of the rinsing component to stop the chemical reaction and wash away the softened chemical sludge, while acid washing test is performed at the same time.

[0025] S106, Mechanical fine cleaning; When the moving device moves the mold of the electric chuck to the cleaning mechanism area, the mold inside the electric chuck rotates to 180°. After chemical soaking and rinsing, the cleaning mechanism uses the nylon brush disc in the flexible tool of the angle grinder to remove the dirt on the inner wall and the outside of the mold at 90° and 180°, respectively, which has softened the scale layer.

[0026] S107. After cleaning: The mold inside the electric chuck is moved downward by the moving device. When it moves downward along the long hole, the downward air resistance acts on the inner wall of the mold, and the airflow blows away all the dust and debris inside the mold until the mold returns to the support frame. The mold is then hoisted to the designated storage area or prepared for the next production cycle.

[0027] Preferably, the pickling test involves using a semiconductor pen pH meter to test the inner wall of the mold after rinsing until the inner wall of the mold is neutral. If it is still acidic, rinsing must continue until the standard is met.

[0028] The beneficial effects of this invention are:

[0029] The mold in the chemical cleaning tank is slowly lifted by the transfer structure and transferred to the area of ​​the electric chuck along with the mold on the support frame. During the transfer, the mold is drained on the support frame, allowing most of the acid to flow back into the tank. At the same time, the photoelectric sensor transmits a signal to the electric telescopic rod, which in turn drives the electric chuck to clamp the mold. After clamping, the moving device drives the pipe pile steel mold in the electric chuck to move along the long hole and pass through the flushing component and cleaning mechanism in sequence, and flips in the flushing component area.

[0030] The process continues until the cleaning mechanism stops, allowing for a thorough rinse of the mold's interior and exterior walls during movement. This stops the chemical reaction and removes the softened chemical sludge. Simultaneously, as the moving device moves the mold in the electric chuck to the cleaning mechanism area, an angle grinder is used to remove the softened scale from the mold's interior and exterior walls. After cleaning, the moving device moves the overturned mold in the electric chuck downwards until it returns to the support frame for hoisting. This combination of chemical and mechanical cleaning maximizes cleaning efficiency while minimizing cleaning time. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, a pipe pile steel mold cleaning device includes a chemical cleaning tank 1 and an angle grinder 91. A support frame 3 is installed symmetrically on the top of the chemical cleaning tank 1. An elongated hole 31 is opened on one side of the support frame 3. An electric chuck 5 for clamping the pipe pile steel mold is slidably installed inside the elongated hole 31.

[0044] The chemical cleaning tank 1 is equipped with a support frame 2 for supporting the steel mold of the pipe pile. A transfer structure 6 is provided on one side of the support frame 2. The transfer structure 6 includes a photoelectric sensor 67. The transfer structure 6 is installed on one side of the chemical cleaning tank 1 and is used to transfer the steel mold of the pipe pile on the support frame 2 to the clamping area of ​​the electric chuck 5.

[0045] The top of the support frame 3 is fixedly installed with an installation platform 10. The installation platform 10 is provided with a cleaning mechanism 9 for driving the angle grinder 91 to move. A flushing assembly 4 is provided on one side of the installation platform 10. The flushing assembly 4 is used to flush the steel mold of the pipe pile during the pickling and turning process.

[0046] The electric chuck 5 is provided with an electric telescopic rod 7 at its end. The electric telescopic rod 7 is electrically connected to the photoelectric sensor 67. The electric telescopic rod 7 is provided with a moving device 8 at its end. The moving device 8 is used to drive the steel mold of the pipe pile in the electric chuck 5 to move along the long hole 31, and at the same time flip over in the area of ​​the cleaning mechanism 9 and the flushing component 4.

[0047] In this embodiment, the mold in the chemical cleaning tank 1 is slowly lifted by the transfer structure 6, and the mold on the support frame 2 is transferred to the area of ​​the electric chuck 5. During the transfer, the mold is drained on the support frame 2, allowing most of the acid to flow back into the tank. At the same time, the photoelectric sensor 67 transmits a signal to the electric telescopic rod 7, which in turn drives the electric chuck 5 to clamp the mold. After clamping, the pipe pile steel mold in the electric chuck 5 is driven by the moving device 8 to move along the long hole 31 and pass through the flushing assembly 4 and the cleaning mechanism 9 in sequence, and is flipped in the area of ​​the flushing assembly 4.

[0048] Until the cleaning mechanism 9 stops, the mold inside and outside, as well as the inner wall, can be thoroughly rinsed during the movement to stop the chemical reaction and wash away the softened chemical sludge. At the same time, when the moving device 8 moves the mold of the electric chuck 5 to the area of ​​the cleaning mechanism 9, the mold inside the electric chuck 5 rotates to 180°. After chemical soaking and rinsing, the cleaning mechanism 9 uses an angle grinder 91 to remove the dirt on the inner and outer walls of the mold with softened scale at 90° and 180° respectively. After cleaning, the moving device 8 moves the mold inside the flipped electric chuck 5 downward. When moving downward along the elongated hole 31, the downward air resistance acts on the inner wall of the mold, and the airflow blows away all the dust and debris inside the mold until the mold returns to the support frame 2 for hoisting. The combination of chemical cleaning and mechanical cleaning can maximize cleaning efficiency while shortening the cleaning time.

[0049] As one implementation method, such as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the mobile device 8 includes a drive cylinder 81 fixedly installed on one side of the chemical cleaning tank 1, and a moving base 82 is fixedly installed on the output end of the drive cylinder 81.

[0050] A movable guide rail 83 is fixedly installed on one side of the support frame 3, and a slider 84 is fixedly installed on one side of the movable seat 82. The slider 84 is slidably installed inside the movable guide rail 83.

[0051] The electric telescopic rod 7 passes through the other side of the movable seat 82, and a gear 86 is fixedly installed at the end of the electric telescopic rod 7. A ratchet 85 is provided between the gear 86 and the electric telescopic rod 7. A toothed plate 87 corresponding to the gear 86 is fixedly installed on one side of the movable guide rail 83.

[0052] Meanwhile, the clamping structure of the electric chuck 5 for the mold is a publicly available technology, which will not be described in detail here. Furthermore, the gear 86 and the ratchet 85 are an internal ratchet gear, which can be referred to in the announcement number CN205978333U.

[0053] In this embodiment, the moving seat 82 is driven to move up and down reciprocally by the driving cylinder 81. During the movement, the slider 84 on one side of the moving seat 82 slides inside the moving guide rail 83 to ensure vertical movement. At the same time, the electric chuck 5 driven by the electric telescopic rod 7 on the other side of the moving seat 82 clamps the pipe pile mold and moves together. During the movement, when the gear 86 meshes with the toothed plate 87 installed on one side of the moving guide rail 83, it drives the pipe pile mold in the electric chuck 5 to rotate simultaneously. During the rotation, it passes through the flushing component 4 and the cleaning mechanism 9. When the driving cylinder 81 drives the moving seat 82 to retract, the ratchet 85 set inside the gear 86 prevents the mold clamped by the electric chuck 5 from rotating because the inner wall of the overturned mold faces down and moves vertically downward.

[0054] As one implementation method, such as Figure 7 As shown, the electric telescopic rod 7 is externally fixedly mounted with a bracket 71, and guide wheels 72 are rotatably connected to both ends of the bracket 71. A positioning plate 73 is fixedly installed between the movable seat 82 and the support frame 3. The positioning plate 73 has a channel 74 corresponding to the elongated hole 31 inside, and the entrance end of the channel 74 is set at an angle.

[0055] In this embodiment, when the drive cylinder 81 drives the movable seat 82 to retract, the electric telescopic rod 7 slides inside the elongated hole 31 until the guide wheel 72 on the outer bracket 71 of the electric telescopic rod 7 passes through the oblique opening of the channel 74 opened by the positioning plate 73, so that the movable seat 82 can quickly and accurately enter after returning to its original position, thus avoiding mold rotation.

[0056] As one implementation method, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, the transfer structure 6 includes a housing 61 fixedly installed on one side of the chemical cleaning tank 1. A movable cylinder 62 is movably installed on one side of the housing 61. A support arm 63 is slidably installed inside the housing 61, and a guide hole 64 corresponding to the support arm 63 is opened inside the housing 61. A photoelectric sensor 67 is installed in the guide hole 64. The output end of the movable cylinder 62 is fixedly connected to the support arm 63, and the bottom end of the support arm 63 is fixedly installed on one side of the support frame 2.

[0057] In this embodiment, multiple sets of applicating rollers 21 are installed on the support frame 2. The applicating rollers 21 conform to the shape of the outside of the pipe pile mold and facilitate transfer. The moving cylinder 62 drives the support arm 63 to slide inside the guide hole 64. When the moving cylinder 62 retracts, the support arm 63 pulls the support frame 2 to move into the chemical cleaning tank 1 for chemical pickling. After chemical cleaning, the moving cylinder 62 is pushed out. Due to the L-shaped guide hole 64, the support arm 63 drives the support frame 2 to move along the L-shaped trajectory to the clamping area of ​​the electric chuck 5 until the photoelectric sensor 67 transmits a signal to the electric telescopic rod 7.

[0058] As one implementation method, such as Figure 8 As shown, multiple sets of telescopic arms 65 are fixedly installed on both sides of the support frame 2, and a fixed column 66 passes through one end of each set of telescopic arms 65. The fixed column 66 is fixedly installed on one side of the chemical cleaning tank 1.

[0059] In this embodiment, when the support frame 2 is pulled back by the moving cylinder 62, the telescopic arms 65 at both ends of the support frame 2 slide on the fixed column 66, thereby greatly increasing the load-bearing capacity of the support frame 2 and preventing displacement during transportation.

[0060] As one implementation method, such as Figure 1 , Figure 2 , Figure 3 and Figure 9 As shown, the cleaning mechanism 9 includes ball screws 93 rotatably mounted on the top and side of the mounting platform 10, respectively. Both sets of ball screws 93 are threadedly connected to connectors 96. An angle grinder 91 is mounted at the end of the connector 96. The connector 96 is telescopic. The ends of the two sets of ball screws 93 are fixedly mounted with pulleys 94. A connecting belt 95 is sleeved between two adjacent sets of pulleys 94. The connector 96 consists of a V-shaped rod 97 and a straight rod 98.

[0061] A servo motor 92 is fixedly installed at the top of the mounting platform 10, and the output end of the servo motor 92 is fixedly connected to the ball screw 93.

[0062] In this embodiment, the ball screw 93 is driven to rotate by the servo motor 92, and the pulley 94 at the end of the ball screw 93 rotates at the same time. The two sets of ball screws 93 are driven to rotate at the same time by the connecting belt 95. When the mold after chemical soaking and rinsing is moved to the cleaning mechanism 9 area by the moving device 8, the mold inside the electric chuck 5 rotates to 90°, and the inner wall of the pipe pile mold faces the angle grinder 91 on one of the straight rods 98, so that the inner wall is processed first.

[0063] When the mold is rotated to 180°, the scale inside the mold has softened. Use the V-bar 97 and the nylon brush disc in the flexible tool of the angle grinder 91 to remove the dirt from the inner and outer walls.

[0064] As one implementation method, such as Figure 3 , Figure 4 , Figure 5 As shown, the rinsing assembly 4 includes a water inlet housing 41 fixedly installed on one side of the installation platform 10. Multiple sets of water inlet housings 41 are provided, and a connecting water pipe 42 is connected between two adjacent sets of water inlet housings 41. High-pressure nozzles 43 are arrayed on one side of the multiple sets of water inlet housings 41. A water inlet pipe 44 is fixedly connected to the other side of the water inlet housing 41. The other side of the chemical cleaning tank 1 is fixedly installed with a water collection tank 45. The high-pressure nozzles 43 are inclined, with an inclination angle between 5° and 15°.

[0065] In this embodiment, an external water pump is connected through the water inlet pipe 44. Through the connection between the water inlet housing 41 and the connecting water pipe 42, water is sprayed out through the high-pressure nozzle 43 and applied to the surface of the mold. At the same time, since the mold is driven to rotate by the moving device 8 during the movement, the inner and outer walls of the mold can be thoroughly rinsed when the rinsing component 4 is rinsing, so as to stop the chemical reaction and wash away the softened chemical sludge, and perform acid washing test.

[0066] Working principle: In advance, use special slow-release industrial hydrochloric acid in chemical cleaning tank 1, dilute the concentrate with water according to the ratio, and use a crane to steadily and slowly lift the mold into the support frame 2 in chemical cleaning tank 1. The moving cylinder 62 drives the support arm 63 to slide inside the guide hole 64. When the moving cylinder 62 retracts, the support arm 63 pulls the support frame 2 into the interior of chemical cleaning tank 1 for chemical acid washing, causing the mold to be completely immersed in the acid solution. The concentration is controlled between 5% and 15%, the reaction temperature is controlled between 20 and 40℃, and the soaking time is 4-8 hours. The generation of bubbles in the tank can be used as an auxiliary judgment.

[0067] After chemical cleaning, the mold is slowly lifted, and the moving cylinder 62 extends. Due to the L-shaped guide hole 64, the support arm 63 drives the carrier frame 2 to move along the L-shaped trajectory into the clamping area of ​​the electric chuck 5. The carrier frame 2 and the mold are transferred together into the area of ​​the electric chuck 5. During the transfer, the mold is drained on the carrier frame 2, allowing most of the acid to flow back into the tank. After being transferred to the area of ​​the electric chuck 5, the photoelectric sensor 67 transmits a signal to the electric telescopic rod 7, which in turn drives the electric chuck 5 to clamp the mold. After clamping, the mold is then... The drive cylinder 81 drives the moving seat 82 to move up and down reciprocally. During the movement, the slider 84 on one side of the moving seat 82 slides inside the moving guide rail 83 to ensure vertical movement. At the same time, the electric chuck 5 driven by the electric telescopic rod 7 on the other side of the moving seat 82 clamps the pipe pile mold and moves together. During the movement, when the gear 86 meshes with the toothed plate 87 installed on one side of the moving guide rail 83, it drives the pipe pile mold in the electric chuck 5 to rotate at the same time. During the rotation, it passes through the flushing component 4 and the cleaning mechanism 9 until it stops in the cleaning mechanism 9.

[0068] In the rinsing assembly 4 area, an external water pump is connected through the water inlet pipe 44. Through the connection between the water inlet housing 41 and the connecting water pipe 42, water is sprayed out through the high-pressure nozzle 43 and applied to the surface of the mold. At the same time, since the mold is driven to rotate by the moving device 8 during the movement, the inner and outer walls of the mold can be thoroughly rinsed during the rinsing assembly 4 to stop the chemical reaction and wash away the softened chemical sludge, and perform acid washing test. When the moving device 8 moves the mold of the electric chuck 5 to the cleaning mechanism 9 area, the mold inside the electric chuck 5 rotates to 180°. After chemical soaking and rinsing, the cleaning mechanism 9 uses the nylon brush disc in the flexible tool of the angle grinder 91 to remove the dirt on the inner and outer walls of the mold at 90° and 180°, respectively, for the mold with softened scale layer.

[0069] When the drive cylinder 81 drives the moving seat 82 to retract, the ratchet 85 inside the gear 86, which meshes with the toothed plate 87, prevents the mold held by the electric chuck 5 from rotating. As the mold moves downward along the elongated hole 31 with its inner wall facing down, the downward air resistance acts on the inner wall of the mold, using airflow to blow away all the dust and debris inside the mold. The electric telescopic rod 7 slides inside the elongated hole 31 until the guide wheel 72 on the outer support 71 of the electric telescopic rod 7 passes through the oblique opening of the channel 74 opened by the positioning plate 73, allowing the moving seat 82 to return to its original position and quickly and accurately enter, preventing the mold from rotating, until the mold returns to the support frame 2. The mold is then hoisted to the designated storage area or prepared for the next production cycle.

[0070] This specification also provides an embodiment of a method for cleaning steel molds for pipe piles, which is applied to a steel mold cleaning device for pipe piles and includes the following steps:

[0071] S101. Preliminary pre-cleaning: After the production process is completed, confirm that the pipe piles inside the mold have been completely lifted out, receive the mold, and conduct a preliminary visual inspection. While the mold is still warm, use tools to quickly tap and peel off large pieces of loose concrete residue from the inner wall of the mold, the joint seam, and the flanges at both ends.

[0072] S102. Chemical Immersion Cleaning: In advance, use special slow-release industrial hydrochloric acid in chemical cleaning tank 1, dilute the concentrated solution with water according to the ratio, and use a crane to steadily and slowly lift the mold into the support frame 2 in chemical cleaning tank 1. The mold is then driven downward by the transfer structure 6 to be completely immersed in the acid solution. The concentration is controlled between 5% and 15%, the reaction temperature is controlled between 20 and 40°C, and the soaking time is 4-8 hours. The situation of bubble generation in the tank can be used as an auxiliary judgment.

[0073] S103, Transfer after soaking: Use the transfer structure 6 to slowly lift the mold and transfer the support frame 2 and the mold together to the area of ​​the electric chuck 5. During the transfer, the mold is placed on the support frame 2 to drain, allowing most of the acid to flow back into the tank.

[0074] S104. Moving and cleaning mold: After being transferred to the area of ​​electric chuck 5, photoelectric sensor 67 transmits a signal to electric telescopic rod 7, which in turn drives electric chuck 5 to clamp the mold. After clamping, the moving device 8 drives the pipe pile steel mold in electric chuck 5 to move along the long hole 31 and pass through flushing assembly 4 and cleaning mechanism 9 in sequence. It flips in the area of ​​flushing assembly 4 until it stops in cleaning mechanism 9.

[0075] S105, Tilting and rinsing the mold: In the rinsing component 4 area, the high-pressure nozzle 43 of the rinsing component 4 is used to rinse the mold at a pressure of 80-150 Bar for 5-15 minutes and maintain a flow rate of 20-25 L / min. Since the mold is driven to rotate by the moving device 8 during the movement, the mold can be thoroughly rinsed inside and outside and inside the mold during the rinsing of the rinsing component 4 to stop the chemical reaction and wash away the softened chemical sludge, while acid washing test is performed at the same time.

[0076] S106, Mechanical fine cleaning; When the moving device 8 moves the mold of the electric chuck 5 to the area of ​​the cleaning mechanism 9, the mold inside the electric chuck 5 rotates to 180°. After chemical soaking and rinsing, the cleaning mechanism 9 uses the nylon brush disc in the flexible tool of the angle grinder 91 to remove the dirt on the inner wall and the outside of the mold at 90° and 180°, respectively, for the mold whose scale layer has been softened.

[0077] S107. After cleaning: The mold inside the electric chuck 5, which has been flipped over, is moved downward by the moving device 8. When it moves downward along the long hole 31, the downward air resistance acts on the inner wall of the mold, and the airflow blows away all the dust and debris inside the mold until the mold returns to the support frame 2. The mold is then hoisted to the designated storage area or prepared for the next production cycle.

[0078] Preferably, the pickling test involves using a semiconductor pen pH meter to test the inner wall of the mold after rinsing until the inner wall of the mold is neutral. If it is still acidic, rinsing must continue until the standard is met.
