[0002] Precast reinforced concrete pipe piles are structural components widely used in infrastructure construction, mainly used to support the loads of buildings and infrastructure, and are commonly found in bridges, buildings, roads and other civil engineering projects. Their main materials are composed of concrete and steel bars, providing durability and tensile strength. In the prior art, when processing reinforced concrete pipe piles, due to the certain length of the mold, when spraying the mold release agent into the mold, it is necessary to walk a long distance from the head end to the tail end of the mold, and it is not conducive to improving the efficiency of the mold release agent spraying operation. At the same time, after the mold is opened, the inner wall of the mold is prone to residual undried slurry and residues.

[0013] Preferably, a pry wheel is fixedly connected to one side of the surface of the ratchet wheel. The pry wheel is arranged below and in contact with the support plate. The pry wheel is used to pry up one end of the support plate.

[0014] Preferably, the shredding spray gun is arranged at the end near the lower die, and is used to flush the liquid and shredded materials generated by flushing the lower die spray gun out of the lower die.

[0015] Preferably, a usage method of a precast reinforced concrete pipe pile forming and processing device includes the following steps:

[0016] S1: Before the processing of the concrete pipe pile starts, control the ends of the two hydraulic cylinders to retract synchronously. The ends of the hydraulic cylinders pull the second cross bar, so that the second cross bar drives the second connecting rod to rotate. Through the connection between the second connecting rod, the synchronous rod, the lifting arm and the lifting support plate, the upper die is lifted. The upper die rotates with the connection between the lifting arm and the frame as the axis, and the space between the upper die and the lower die is opened. The angle between the second connecting rod and the first connecting rod continuously decreases. When the lifting arm rotates 90 degrees, the upper die is flipped 90 degrees, and the second connecting rod and the first connecting rod are retracted into the frame.

[0017] S2: During the rotation of the lifting arm, the set outer fillet contacts the inner fillet of the support seat and presses the support seat downward. During this process, the first spring is gradually compressed. When the bent bar moves downward following the support seat, it drives the mounting plate and the upper die spray gun to move downward synchronously. At the same time, the rack fixedly connected to the bottom of the support seat moves downward and drives the first gear and the rotating shaft to rotate. When the support seat moves downward, the pressure bar fixedly connected to one of the support seats also moves downward, causing the ratchet wheel to rotate.

[0018] S3: When the rotating shaft rotates, through meshing and driving with Gear III, Gear III drives Gear II and the toothed disc to rotate. When the toothed disc rotates, the turntable follows the rotation, causing the spray nozzles of the demolding liquid spray gun and the lower die spray gun to deflect downward towards the mold. After the output end of the hydraulic cylinder is fully retracted, the lifting arm stops rotating, the upper mold stops flipping, the spray nozzle of the upper mold spray gun aligns with the top of the inner wall of the upper mold, and the spray nozzles of the demolding liquid spray gun and the lower die spray gun align with the edge of the inner wall of the lower mold. Subsequently, start the demolding liquid spray gun to spray demolding liquid onto the inner wall of the lower mold. After spraying, place a wire cage into the lower mold, then conduct concrete placement. Subsequently, start the hydraulic rod to output outward, causing the spray gun to reset, and the upper mold and the lower mold are closed. After closing, the output end of the air cylinder outputs outward, causing the two clamping arms to open and disengage from the clamping connection with the guide groove. Subsequently, start the drive motor to drive the centrifugal wheel to rotate, perform centrifugal operation on the mold. After centrifugation, conduct steam rapid forming. Subsequently, start the output end of the hydraulic cylinder to retract, and the output end of the air cylinder to retract inward, causing the clamping arms to clamp the upper mold. After the upper mold is opened, remove the concrete pipe pile from the inside of the lower mold. The lifting arm presses down the support seat again and drives the upper mold spray gun to align with the upper mold, and the demolding liquid spray gun and the lower die spray gun to align with the lower mold. The upper mold spray gun and the lower die spray gun are started simultaneously to wash the residual slurry and debris on the inner wall of the mold;

[0019] S4: When one of the support seats moves downward and drives the pressure rod to move, the tooth plate clamps the edge of the ratchet wheel and causes the ratchet wheel to rotate. During the upward movement of the support seat, the tooth plate is blocked by the ratchet wheel, causing the tooth plate to compress Spring II and reset the tooth plate. After each rotation of the ratchet wheel, the limit plate clamps the edge of the ratchet wheel for limiting. When the upper mold is opened for the second time, the ratchet wheel drives the pry wheel to rotate upward, causing the pry wheel to pry one end of the support plate upward, making the overall lower mold tilt. When the spray gun washes the inner wall of the lower mold, the waste liquid and debris flow downward to the lower part of the lower mold. There is a debris spray gun near the lower part of the lower mold. Start this spray gun to flush the debris and waste liquid out of the lower mold.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. In the present invention, through the provided mold opening mechanism, before processing the concrete pipe pile, by installing a circular ring on the outer wall of the mold and opening a guide groove, controlling the air cylinder to retract inward so that the clamping arms clamp the upper mold, and flipping the upper mold through the hydraulic cylinder. After closing the mold, the air cylinder automatically extends outward, causing the clamping arms to loosen the clamping of the upper mold, which is convenient for controlling the opening and closing of the mold and avoiding frequent hoisting and disassembly of the mold;

[0022] 2. In the present invention, through the provided triggering mechanism, during the process of the upper mold being opened, the support base is pressed down, enabling the triggering mechanism to drive the deflection mechanism to operate. The turntable rotates on the base, causing the demolding liquid spray gun to rotate and align the nozzle with the inner wall of the lower mold, performing the demolding agent spraying operation on the lower mold. When the upper mold is opened for the second time, the upper mold spray gun moves downward, aligning the nozzle with the inner wall of the upper mold. At the same time, the nozzle of the lower mold spray gun aligns with the inner wall of the lower mold, cleaning the inner walls of the upper mold and the lower mold. This not only enables rapid spraying of the demolding agent but also keeps the inside of the mold clean, facilitating subsequent use of the mold.

[0023] 3. In the present invention, through the provided prying mechanism, when the upper mold is opened for the second time, the prying wheel rotates upward driven by the ratchet. During this process, one end of the support plate is lifted, tilting the lower mold. The liquid and scraps that have been rinsed inside the lower mold flow to the lower part, and the scrap spray gun flushes out the accumulated waste liquid and scraps outside the lower mold. Lifting one end of the mold after rinsing facilitates the unified treatment of the waste liquid and scraps, further improving the efficiency of mold cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Embodiment Three:

[0047] The mold prying mechanism 8 includes a pressure bar 801. The pressure bar 801 is fixedly connected to one of the support seats 602.

[0048] In this embodiment, as Figure 10 shown, when the upper mold 4 is opened after the processing of the device is completed, the support seat 602 moves downward, so that the prying wheel 807 rotates upward with the middle of the ratchet 805 as the axis, prying up the bottom of the support plate 201, and the scrap material spray gun 9 does not come into contact with it during the opening process of the upper mold 4.

[0049] Usage method and advantages of the present invention: The usage method of a precast reinforced concrete pipe pile forming and processing device is as follows. The working process is as follows:

[0050] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 shown:

[0051] S1: Before the processing of the concrete pipe pile starts, control the ends of the two hydraulic cylinders 502 to retract synchronously. The ends of the hydraulic cylinders 502 pull the second cross bar 505, causing the second cross bar 505 to drive the second connecting rod 504 to rotate. Through the connection between the second connecting rod 504, the synchronous rod 506, the lifting arm 507, and the lifting support plate 508, the upper mold 4 is lifted. The upper mold 4 rotates around the connection point between the lifting arm 507 and the frame 1 as the axis, and the space between the upper mold 4 and the lower mold 3 is opened. The angle between the second connecting rod 504 and the first connecting rod 503 continuously decreases. When the lifting arm 507 rotates 90 degrees, the upper mold 4 is flipped 90 degrees, and the second connecting rod 504 and the first connecting rod 503 are retracted into the frame 1;

[0052] S2: During the rotation of the lifting arm 507, the set outer fillet contacts the inner fillet of the support seat 602 and presses the support seat 602 downward. During this process, the first spring 607 is gradually compressed. When the bent bar 601 moves downward following the support seat 602, it drives the mounting plate 603 and the upper die spray gun 604 to move downward synchronously. At the same time, the rack 605 fixedly connected to the bottom of the support seat 602 moves downward and drives the first gear 606 and the rotating shaft 608 to rotate. When the support seat 602 moves downward, the pressure rod 801 fixedly connected to one of the support seats 602 also moves downward, causing the ratchet 805 to rotate;

[0053] S3: When the rotating shaft 608 rotates, through meshing transmission with the third gear 704, the third gear 704 drives the second gear 703 and the toothed disc 702 to rotate. When the toothed disc 702 rotates, the turntable 705 rotates accordingly, causing the spray nozzles of the demolding liquid spray gun 706 and the lower mold spray gun 707 to deflect downward towards the lower mold 3. After the output end of the hydraulic cylinder 502 is fully retracted, the lifting arm 507 stops rotating, the upper mold 4 stops flipping, the spray nozzle of the upper mold spray gun 604 is aligned with the top of the inner wall of the upper mold 4, and the spray nozzles of the demolding liquid spray gun 706 and the lower mold spray gun 707 are aligned with the edge of the inner wall of the lower mold 3. Subsequently, the demolding liquid spray gun 706 is activated to spray demolding liquid onto the inner wall of the lower mold 3. After spraying, a steel wire cage is placed into the lower mold 3, and then concrete is fed. Subsequently, the hydraulic rod 801 is activated to output outward, causing the spray gun to reset. The upper mold 4 and the lower mold 3 are closed. After closing, the output end of the air cylinder 509 outputs outward, causing the two clamping arms 511 to open and disengage from the clamping connection with the guide groove 302. Subsequently, the drive motor 203 is activated to drive the centrifugal wheel 204 to rotate, performing a centrifugal operation on the mold. After centrifugation, steam rapid forming is carried out. Subsequently, the output end of the hydraulic cylinder 502 is retracted again, and the output end of the air cylinder 509 is retracted inward, causing the clamping arms 511 to clamp the upper mold 4. After the upper mold 4 is opened, the concrete pipe pile is removed from the inside of the lower mold 3. The lifting arm 507 presses down the support seat 602 again and drives the upper mold spray gun 604 to align with the upper mold 4, and the demolding liquid spray gun 706 and the lower mold spray gun 707 are aligned with the lower mold 3. The upper mold spray gun 604 and the lower mold spray gun 707 are activated simultaneously to wash the residual slurry and broken materials on the inner wall of the mold.

[0054] S4: When one of the support seats 602 moves downward and drives the pressure rod 801 to move, the toothed plate 802 catches the edge of the ratchet wheel 805 and causes the ratchet wheel 805 to rotate. During the upward movement of the support seat 602, the toothed plate 802 is blocked by the ratchet wheel 805, causing the toothed plate 802 to compress the second spring 804 and reset the toothed plate 802. After each rotation of the ratchet wheel 805, the limiting plate 806 catches the edge of the ratchet wheel 805 for limiting. When the upper mold 4 is opened for the second time, the ratchet wheel 805 drives the pry wheel 807 to rotate upward, causing the pry wheel 807 to pry one end of the support plate 201 upward, making the entire lower mold 3 tilt. When the spray gun washes the inner wall of the lower mold 3, the waste liquid and broken materials flow downward to the lower part of the lower mold 3. There is a broken material spray gun 9 near the lower part of the lower mold 3. Activate this spray gun to flush the broken materials and waste liquid out of the lower mold 3.

[0055] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.

10. The usage method of a precast reinforced concrete pipe pile forming and processing device according to claim 1, characterized in that, It includes the following steps: S1: Before the processing of the concrete pipe pile starts, control the ends of the two hydraulic cylinders (502) to retract synchronously. The ends of the hydraulic cylinders (502) pull the second cross bar (505), causing the second cross bar (505) to drive the second connecting rod (504) to rotate. Through the connection between the second connecting rod (504), the synchronizing rod (506), the lifting arm (507), and the lifting support plate (508), the upper die (4) is lifted. The upper die (4) rotates with the connection between the lifting arm (507) and the frame (1) as the axis, and the space between the upper die (4) and the lower die (3) is opened. The angle between the second connecting rod (504) and the first connecting rod (503) continuously decreases. When the lifting arm (507) rotates 90 degrees, the upper die (4) is flipped 90 degrees, and the second connecting rod (504) and the first connecting rod (503) are retracted into the frame (1). S2: During the rotation of the lifting arm (507), the set outer fillet contacts the inner fillet of the support seat (602) and presses the support seat (602) downward. During this process, the first spring (607) is gradually compressed. When the bent bar (601) moves downward following the support seat (602), it drives the mounting plate (603) and the upper die spray gun (604) to move downward synchronously. At the same time, the rack (605) fixedly connected to the bottom of the support seat (602) moves downward and drives the first gear (606) and the rotating shaft (608) to rotate. When the support seat (602) moves downward, the pressure rod (801) fixedly connected to one of the support seats (602) also moves downward, causing the ratchet wheel (805) to rotate. S3: When the rotating shaft (608) rotates, through meshing transmission with the third gear (704), the third gear (704) drives the second gear (703) and the toothed disc (702) to rotate. When the toothed disc (702) rotates, the turntable (705) rotates accordingly, causing the spray nozzles of the demolding liquid spray gun (706) and the lower die spray gun (707) to deflect downward towards the lower die (3). After the output end of the hydraulic cylinder (502) is fully retracted, the lifting arm (507) stops rotating, the upper die (4) stops flipping, the spray nozzle of the upper die spray gun (604) aligns with the top of the inner wall of the upper die (4), and the spray nozzles of the demolding liquid spray gun (706) and the lower die spray gun (707) align with the edge of the inner wall of the lower die (3). Subsequently, the demolding liquid spray gun (706) is activated to spray demolding liquid onto the inner wall of the lower die (3). After spraying, a wire cage is placed into the lower die (3), and then concrete is fed. Subsequently, the hydraulic rod (801) is activated to output outward, resetting the spray gun. The upper die (4) and the lower die (3) are closed. After closing, the output end of the air cylinder (509) outputs outward, causing the two clamping arms (511) to open and disengage from the clamping connection with the guide groove (302). Subsequently, the drive motor (203) is activated to drive the centrifugal wheel (204) to rotate, performing a centrifugal operation on the mold. After centrifugation, rapid steam forming is carried out. Subsequently, the output end of the hydraulic cylinder (502) is retracted again, and the output end of the air cylinder (509) is retracted inward, causing the clamping arms (511) to clamp the upper die (4). After the upper die (4) is opened, the concrete pipe pile is removed from the inside of the lower die (3). The lifting arm (507) presses down the support seat (602) again and drives the upper die spray gun (604) to align with the upper die (4), and the demolding liquid spray gun (706) and the lower die spray gun (707) to align with the lower die (3). The upper die spray gun (604) and the lower die spray gun (707) are activated simultaneously to wash the residual slurry and debris on the inner wall of the mold; S4: When one of the support seats (602) moves downward and drives the pressure rod (801) to move, the toothed plate (802) catches the edge of the ratchet wheel (805) and causes the ratchet wheel (805) to rotate. During the upward movement of the support seat (602), the toothed plate (802) is blocked by the ratchet wheel (805), causing the toothed plate (802) to compress the second spring (804) and reset the toothed plate (802). After each rotation of the ratchet wheel (805), the limiting plate (806) catches the edge of the ratchet wheel (805) for limiting. When the upper die (4) is opened for the second time, the ratchet wheel (805) drives the pry wheel (807) to rotate upward, causing the pry wheel (807) to pry one end of the support plate (201) upward, tilting the entire lower die (3). When the spray gun washes the inner wall of the lower die (3), the waste liquid and debris flow downward to the lower part of the lower die (3). There is a debris spray gun (9) near the lower part of the lower die (3). Activate this spray gun to flush the debris and waste liquid out of the lower die (3).
