Description

Technical Field

[0001] This invention relates to the field of concrete pipe pile technology, and more specifically, to a processing and shaping device for prestressed high-strength concrete pipe piles. Background Technology

[0002] Concrete pipe pile processing equipment refers to a specialized mechanical system that uses prestressed concrete technology and centrifugal molding to process raw materials such as cement, sand, and steel bars into hollow, slender precast concrete components. In traditional production methods, raw material proportioning often relies on manual labor, which results in low precision, time-consuming and labor-intensive processes, and a high rate of defective products. At the same time, material adhesion during the mixing process also makes equipment cleaning extremely difficult. Modern processing equipment was developed to solve these pain points. It integrates mechanical, hydraulic, and electrical automation technologies to achieve mechanized operation of the entire process from steel bar processing, concrete mixing, placement, molding to curing. It is a key hardware foundation for ensuring the high strength and high quality of pipe piles.

[0003] In the concrete pouring process during the fabrication of concrete pipe piles, the bundled and welded steel reinforcement frame is placed inside the mold. The concrete pouring equipment extends the concrete pouring pipe from one circular end of the mold into the other end inside the mold, and concrete is poured from inside the mold through the pouring pipe. At the same time, the pouring pipe is moved. This pouring method is faster than pouring directly from above the mold and does not put pressure on the steel reinforcement frame.

[0004] In the centrifugal process after the concrete is poured, the combined mold is usually placed on top of multiple symmetrically distributed support rollers. The drive mechanism drives multiple support rollers on one side of the mold to rotate, which in turn drives the cylindrical mold to rotate, thereby centrifuging the concrete inside the mold. However, traditional support rollers are rigid supports, and even slight eccentricity when the mold rotates at high speed can cause violent vibration. Mold vibration can cause cracks to appear inside the already formed pipe piles, or cause the forming to fail. This increases the number of defective products, reduces processing efficiency, and increases production costs.

[0005] Meanwhile, the energy consumption of traditional centrifugal forming equipment for pipe piles is receiving increasing attention. Centrifugal operation is the most concentrated energy-consuming stage in the pipe pile production process. If the mold experiences eccentricity and vibration, the drive motor load will fluctuate frequently, and the instantaneous power will surge, resulting in a large amount of ineffective energy consumption. Furthermore, the current surge will accelerate the aging of the motor and transmission components. A high defect rate means that the concrete, steel bars, and energy used in the previous centrifugation and steam curing processes for scrapped pipe piles are all wasted, creating a high-energy-consumption and high-waste production situation. Therefore, reducing equipment operating energy consumption and improving energy utilization efficiency while ensuring forming quality and production efficiency has become an important direction for upgrading pipe pile processing equipment. Summary of the Invention

[0006] This invention provides a processing and shaping device for prestressed high-strength concrete pipe piles, solving the technical problem that pipe piles will jump during centrifugal processing in related technologies.

[0007] This invention provides a processing and shaping equipment for prestressed high-strength concrete pipe piles, including a support plate, a drive mechanism, a support lifting mechanism, and an anti-jump mechanism. The drive mechanism and the support lifting mechanism are both fixedly connected to the top of the support plate. The drive mechanism is used to drive the support lifting mechanism to rotate, and the anti-jump mechanism is placed on the top of the support lifting mechanism. The anti-jump mechanism includes a lower mold placed at the top of the support and lifting mechanism. An upper mold is connected to the top of the lower mold.

[0010] In a preferred embodiment, the wedge-shaped groove is connected to an adjacent connecting groove, and the wedge-shaped groove and the wedge-shaped slider form a wedge-shaped fit.

[0011] In a preferred embodiment, the support and lifting mechanism includes multiple sets of bracket bodies, each bracket body being fixedly connected to the top of the support plate. The multiple sets of bracket bodies are equidistantly distributed along the length of the support plate, with two bracket bodies in each set. The two bracket bodies in each set are symmetrically distributed along the width of the support plate. An annular groove is provided at the end of the connecting ring near the drive mechanism. Two round shafts are symmetrically rotatably connected to the top of the bracket body. Rollers are fixedly sleeved on the outside of the round shafts. An elliptical lower pressure roller is fixedly connected to the end of the lower round shaft on each bracket body. The elliptical lower pressure roller is located at the end of the round shaft near the annular groove. After the mold is closed, the annular groove is sleeved on the outside of the elliptical lower pressure roller. Stable rings are fixedly connected at equal intervals on the upper mold and the lower mold.

[0012] In a preferred embodiment, two rollers on each bracket body roll into contact with adjacent receiving rings and stabilizing rings, respectively, and support the receiving rings and stabilizing rings through the rollers. When the receiving rings and stabilizing rings are in contact with the adjacent rollers, the elliptical lower pressure roller extends into the annular groove.

[0013] In a preferred embodiment, the receiving ring is further provided with a self-locking mechanism, which includes a support slide rod fixedly connected inside the annular groove. A sleeve rod is sleeved on the outer side of the end of the support slide rod away from the annular groove. A stabilizing slide groove is provided at both the top and bottom ends of the sleeve rod. A circular slider is slidably connected inside the stabilizing slide groove. The circular slider is fixedly connected to the support slide rod. A relief spring is connected inside the sleeve rod. The two ends of the relief spring abut against the support slide rod and the sleeve rod, respectively.

[0014] In a preferred embodiment, the support slide bar and sleeve bar are parallel to the upper mold, and the stabilizing slide groove is opened along the length direction of the sleeve bar.

[0015] In a preferred embodiment, a rectangular groove is formed in the middle of the bottom of each window, and a groove is formed at the end of the sleeve rod away from the annular groove. A docking support rod is fixedly connected to the middle of the two top ends of the receiving ring set on the lower mold. An elliptical limiting block is rotatably connected to the top of the docking support rod through a limiting shaft. A limiting slot is formed at the upper end of the side of the docking support rod. A positioning ring is fixedly connected to the upper end of the limiting shaft. The upper surface of the elliptical limiting block is in movable contact with the lower surface of the positioning ring. A clearance top groove is formed in the middle of the top of the elliptical limiting block, and a clearance bottom groove is formed in the middle of the bottom of the elliptical limiting block. The clearance top groove and the clearance bottom groove are connected. A limiting block is fixedly connected to the inner wall of the clearance bottom groove.

[0016] In a preferred embodiment, side sealing plates are fixedly connected to both ends of the lower mold, and a pouring hole is opened through the middle of the side sealing plate. A sealing block is slidably connected inside the pouring hole. A sealing plate is fixedly connected to the end of the sealing block away from the receiving ring. The sealing plate is fixedly connected to the side sealing plate by bolts. The end of the upper mold is fixedly connected to the adjacent side sealing plate by bolts.

[0017] The beneficial effects of this invention are as follows: 1. This invention, through the setting of an anti-jump mechanism, uses an elliptical downward pressure roller to limit the downward pressure of the annular groove, ensuring that the mold maintains a stable rotation state throughout the centrifugal process. This allows the concrete to be evenly distributed under centrifugal force, effectively improving the structural density and molding accuracy of the pipe pile, and significantly reducing the probability of defective products such as internal pipe pile cracks and shape deformation caused by the mold.

[0018] 2. The present invention, through the setting of a self-locking mechanism, automatically triggers the self-locking mechanism by means of the action of mold closing process, without the need for additional bolt tightening operation, which greatly improves the mold closing efficiency, reduces the physical exertion of operators, and avoids the difference in force of manual bolt tightening, ensuring uniform mold closing gap and eliminating the risk of slurry leakage from the process level.

[0019] 3. By setting up wedge-shaped sliders and wedge-shaped grooves, the docking guidance function automatically corrects the positional deviation of the upper and lower molds during the mold closing process through inclined plane guidance and adaptive positioning structure. Even if there is a certain error in the initial alignment, it can be automatically adjusted to a precise matching state through the guiding structure, reducing the dependence on the operator's experience, greatly shortening the mold closing alignment time, and improving the consistency of mold closing accuracy.

[0020] 4. While ensuring molding quality and production efficiency, this invention also has significant energy-saving and consumption-reducing effects. The synergistic effect of the anti-jump mechanism and the self-locking mechanism allows the centrifugal operation to be carried out under stable and low-impact conditions. The drive mechanism does not need to frequently overcome the additional resistance caused by mold jumping, which significantly reduces the ineffective power consumption of the drive system during the centrifugal stage. The docking guidance function reduces repeated adjustments and mold friction wear during the mold closing process, which indirectly reduces the energy consumption of auxiliary processes. Stable coaxial rotation avoids the impact of motor load and instantaneous power surge caused by eccentric jumping, shortens the ineffective operating time required to reach the specified density, and improves the overall energy utilization efficiency of the production line. By combining improved molding precision and yield, the repeated energy consumption of substandard pipe piles in mixing, centrifugation, and steam curing processes is further avoided, achieving energy savings throughout the entire process from mold closing and centrifugation to curing, which aligns with the green and low-carbon manufacturing development direction.

[0023] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, a prestressed high-strength concrete pipe pile processing and shaping equipment includes a support plate 1, a drive mechanism 2, a support lifting mechanism and an anti-jump mechanism. The drive mechanism 2 and the support lifting mechanism are both fixedly connected to the top of the support plate 1. The drive mechanism 2 is used to drive the support lifting mechanism to rotate, and the anti-jump mechanism is placed at the top of the support lifting mechanism. The anti-jump mechanism includes a lower mold 41 placed at the top of the support mechanism. An upper mold 42 is connected to the top of the lower mold 41. Receiving rings 43 are fixedly connected at equal intervals on the outer sides of both the upper mold 42 and the lower mold 41. Two symmetrical openings 431 are provided at both ends of the receiving ring 43 on each upper mold 42 along its length. A connecting ring 432 is provided on the side of the receiving ring 43 away from the drive mechanism 2. Several connecting grooves 433 are provided at equal intervals on the receiving ring 43. A stabilizing rod 434 is slidably connected inside the connecting grooves 433. A circular plate is integrally formed at the end of the stabilizing rod 434 away from the connecting ring 432. A retraction spring is sleeved on the outer side of the stabilizing rod 434. One end of the spring is fixedly connected to the receiving ring 43 on the upper mold 42, and the other end is fixedly connected to the circular plate. The spring applies a pulling force to the circular plate, and under the action of the pulling force of the spring, the circular plate tends to move closer to the receiving ring 43. At this time, the circular plate pushes the connecting ring 432 away from the receiving ring 43 through the stabilizing slide rod 434. One end of the stabilizing slide rod 434 is fixedly connected to the connecting ring 432. After the upper mold 42 and the lower mold 41 are closed, the two receiving rings 43 that form a circle are provided with connecting grooves 435 at their opposite ends. A pushing component is provided inside the connecting groove 435. The stabilizing slide rods 434 at both ends of the receiving ring 43 pass through the adjacent connecting grooves 435 respectively.

[0025] Both the upper mold 42 and the lower mold 41 are semi-cylindrical, and their lengths are the same. The receiving ring 43 and the connecting ring 432 are semi-circular components. The two symmetrical receiving rings 43 and the two symmetrical connecting rings 432 are spliced ​​together to form a complete ring component. The diameter of the connecting ring 432 is larger than that of the receiving ring 43. The diameter of the receiving ring 43 is larger than that of the upper mold 42 and the lower mold 41. The centers of the receiving ring 43, the connecting ring 432, the upper mold 42, and the lower mold 41 are at the same position. The upper mold 42 and the lower mold 41 are fixedly connected to the opposite ends with side plates. The side plates extend outward along the radial direction of the upper mold 42 and the lower mold 41. The connecting ring 432 does not contact the side plates.

[0026] like Figure 6 , Figure 7 , Figure 9 , Figure 10 and Figure 11 As shown, the pushing component includes a reset slide groove 436, which passes through the connecting groove 435 on the lower mold 41 near the side of the driving mechanism 2. Each connecting groove 435 on the lower mold 41 is provided with a reset slide groove 436. A wedge-shaped slide groove 437 is provided outside the stabilizing slide rod 434 located in the connecting groove 435. A wedge-shaped slider 438 is slidably connected inside the connecting groove 435 on the lower mold 41. An extension block 439 is slidably connected inside the reset slide groove 436. The extension block 439 is fixedly connected to the adjacent wedge-shaped slider 438. like Figure 9 As shown, a rectangular plate is fixedly connected above the reset slide 436 on the outer surface of the receiving ring 43 of the lower mold 41. A reset spring is connected between the rectangular plate and the extension block 439. One end of the reset spring is fixedly connected to the rectangular plate, and the other end is fixedly connected to the extension block 439. like Figure 11 and Figure 12 As shown, several T-shaped slide rails are fixedly connected to the outer sides of the upper mold 42 and the lower mold 41 at equal intervals. T-shaped sliders are slidably connected inside the T-shaped slide rails. The top of each T-shaped slider is fixedly connected to the adjacent connecting ring 432. like Figure 8 As shown, the wedge-shaped groove 437 is connected to the adjacent connecting groove 435, and the wedge-shaped groove 437 and the wedge-shaped slider 438 form a wedge-shaped fit. The wedge slider 438 has symmetrical inclined surfaces at both ends near the extension block 439. The wedge groove 437 has inclined surfaces inside, and the inclined surfaces inside the wedge groove 437 are parallel to the adjacent inclined surfaces on the wedge slider 438. like Figure 8As shown, in its natural state, the return spring always provides an upward pulling force to the extension block 439. The upper mold 42 has a trapezoidal opening at the groove of the connecting slot 435. The width of the trapezoidal opening is greater than the thickness of the wedge slider 438, and the transition between the trapezoidal opening and the adjacent connecting slot 435 is smoothly connected, so that the upper end of the wedge slider 438 can be accurately inserted into the groove of the connecting slot 435 on the upper mold 42 during the mold closing process. When the mold is not closed, the lower end of the wedge slider 438 does not engage with the adjacent wedge groove 437 under the action of the return spring. At this time, the wedge groove 437 is not aligned with the lower end of the wedge slider 438. When the wedge slider 438 moves downward, the inclined surface at its end will press against the wedge groove 437. During the process of the upper mold 42 and the lower mold 41 being tightly fitted together, the upper end of the wedge slider 438 is first inserted into the slot 435 of the upper mold 42. As the upper mold 42 and the lower mold 41 gradually approach each other, the two ends of the wedge slider 438 are gradually inserted into the adjacent wedge groove 437. The inclined surface of the end of the wedge slider 438 is pressed and contacted with the wedge groove 437. The wedge slider 438 pushes the wedge groove 437 to move, causing the stabilizing slide rod 434 to slide outward along the mating groove 433. At the same time, the stabilizing slide rod 434 drives the connecting ring 432 to move closer to the receiving ring 43. When the upper mold 42 and the lower mold 41 are closed, the wedge-shaped groove 437 on the stabilizing slide bar 434 is fully engaged with the end of the wedge-shaped slider 438. At this time, the connecting ring 432 is close to the receiving ring 43 and fits against the receiving ring 43, thus completing the splicing of the receiving ring 43 and the connecting ring 432.

[0027] like Figure 1 As shown, the support and lifting mechanism includes multiple sets of bracket bodies 3. Each bracket body 3 is fixedly connected to the top of the support plate 1. The multiple sets of bracket bodies 3 are equidistantly distributed along the length direction of the support plate 1. There are two bracket bodies 3 in each set. The two bracket bodies 3 in each set are symmetrically distributed along the width direction of the support plate 1. The connecting ring 432 has an annular groove 44 at one end near the drive mechanism 2. Two round shafts are symmetrically rotatably connected to the top of the bracket body 3. The outside of the round shafts is fixedly sleeved with rollers 31. An elliptical lower pressure roller 32 is fixedly connected to the end of one round shaft below the receiving ring 43 on each bracket body 3. The elliptical lower pressure roller 32 is located at one end of the round shaft near the annular groove 44. After the mold is closed, the annular groove 44 is sleeved on the outside of the elliptical lower pressure roller 32. Stable rings 45 are fixedly connected at equal intervals on the upper mold 42 and the lower mold 41. After installation, the two rollers 31 on each bracket body 3 roll into contact with the adjacent receiving ring 43 and stabilizing ring 45 respectively, and support the receiving ring 43 and stabilizing ring 45 through the rollers 31. like Figure 5As shown, the elliptical lower pressure roller 32 is in a horizontal state in the initial state. At this time, there is a gap between the end of the elliptical lower pressure roller 32 along its minor axis and the groove wall of the annular groove 44. When the elliptical lower pressure roller 32 is driven to rotate by the driving mechanism 2, the end of the elliptical lower pressure roller 32 along its major axis comes into contact with the groove wall of the annular groove 44 on the side away from the lower mold 41. At this time, the elliptical lower pressure roller 32 will press down on the connecting ring 432, thereby preventing the mold connected to the connecting ring 432 from jumping. When the receiving ring 43 and the stabilizing ring 45 are in contact with the adjacent idler roller 31, the elliptical lower pressure roller 32 extends into the annular groove 44.

[0028] like Figure 1 As shown, the drive mechanism 2 includes a horizontal drive assembly and a motor. The horizontal drive assembly can be a linear drive mechanism such as a lead screw assembly, which is existing technology and will not be described in detail here. The motor is mounted on the top of the horizontal drive assembly, and the output end of the motor is fixedly connected to the adjacent idler roller 31. Two sets of transmission rollers are provided on the top of the support plate 1, such as... Figure 1 As shown, each set of drive rollers is equipped with multiple round rollers. After the mold is closed, the outer surfaces of several round rollers are in contact with the outer surfaces of the adjacent receiving ring 43. The end of one set of drive rollers is connected to the output end of the motor. like Figure 5 , Figure 6 and Figure 7 As shown, the receiving ring 43 is also provided with a self-locking mechanism. The self-locking mechanism includes a support slide rod 46 fixedly connected inside the annular groove 44. A sleeve rod 461 is sleeved on the outer side of the support slide rod 46 away from the annular groove 44. Stable slide grooves 462 are opened at the top and bottom of the sleeve rod 461. A circular slider 463 is slidably connected inside the stable slide groove 462. The circular slider 463 is fixedly connected to the support slide rod 46. like Figure 5 and Figure 7 As shown, the sleeve rod 461 has a receiving groove inside the end near the support slide rod 46, the end of the support slide rod 46 is inside the receiving groove, and the stabilizing slide groove 462 is connected to the receiving groove. The sleeve rod 461 is internally connected to a relief spring 464, and the two ends of the relief spring 464 abut against the support slide rod 46 and the sleeve rod 461 respectively. Specifically, the relief spring 464 is installed in the receiving groove. One end of the relief spring 464 is fixedly connected to the innermost side of the receiving groove, and the other end of the relief spring 464 is fixedly connected to the support slide rod 46. The relief spring 464 applies elastic force to the sleeve rod 461. The supporting slide bar 46 and sleeve bar 461 are parallel to the upper mold 42, and the stabilizing groove 462 is opened along the length direction of the sleeve bar 461; A rectangular groove 465 is provided in the middle of the bottom of each window 431. A groove 466 is provided at the end of the sleeve rod 461 away from the annular groove 44. A docking support rod 467 is fixedly connected to the middle of the two top ends of the receiving ring 43 set on the lower mold 41. An elliptical limiting block 468 is rotatably connected to the top of the docking support rod 467 through the limiting shaft 4672. The width of the rectangular groove 465 is greater than the major axis of the elliptical limiting block 468, allowing the elliptical limiting block 468 to pass through the rectangular groove 465 without obstruction. The width of the groove 466 is greater than the minor axis of the elliptical limiting block 468, but less than the major axis of the elliptical limiting block 468. A limiting groove 4671 is provided on the upper end of the side of the docking support rod 467, and a positioning ring is fixedly connected to the upper end of the limiting shaft 4672. The upper surface of the elliptical limiting block 468 is in contact with the lower surface of the positioning ring. The elliptical limiting block 468 has a clearance top groove 4681 in the middle of its top end and a clearance bottom groove 4682 in the middle of its bottom end. The clearance top groove 4681 and the clearance bottom groove 4682 are connected. A limit block 4683 is fixedly connected to the inner wall of the clearance bottom groove 4682. The limiting shaft 4672 is set inside the relief top groove 4681, and the limiting shaft 4672 is slidably connected to the relief top groove 4681. The relief bottom groove 4682 is sleeved on the outside of the upper end of the docking support rod 467, and the docking support rod 467 is slidably connected to the relief bottom groove 4682. The limiting block 4683 and the limiting groove 4671 are fitted together, and the length of the limiting block 4683 is the same as the depth of the limiting groove 4671. At the same time, when the limiting block 4683 and the limiting groove 4671 are fitted together, the limiting shaft 4672 contacts one end of the relief top groove 4681, and the docking support rod 467 contacts one end of the relief bottom groove 4682. At this time, there is a certain sliding gap between the limiting shaft 4672 and the other end of the relief top groove 4681, and there is also a certain sliding gap between the docking support rod 467 and the other end of the relief bottom groove 4682. The length of the sliding gap is greater than the length of the limiting block 4683 inserted into the limiting groove 4671. During normal operation, the limit block 4683 and the limit slot 4671 are in an engaged state; In the initial state, the length direction of the elliptical limiting block 468 is parallel to the width direction of the lower mold 41; When the relief spring 464 is in its natural state, it always provides a thrust to the sleeve rod 461 away from the annular groove 44, and at this time the connecting support rod 467 is in the middle position of the groove 466. When the retraction spring is in its natural state, there is a gap between the end of the sleeve rod 461 away from the annular groove 44 and the adjacent window 431. Both ends of the lower mold 41 are fixedly connected to side sealing plates 4. A pouring hole 5 is opened through the middle of the side sealing plate 4. A sealing block 6 is slidably connected inside the pouring hole 5. A sealing plate 7 is fixedly connected to the end of the sealing block 6 away from the receiving ring 43. The sealing plate 7 is fixedly connected to the side sealing plate 4 by bolts, and the end of the upper mold 42 is fixedly connected to the adjacent side sealing plate 4 by bolts.

[0029] In actual use, the operator places the lower mold 41 on the top of the support lifting mechanism, places the receiving rings 43 and stabilizing rings 45 on both sides of the lower mold 41 on the top of the adjacent roller 31, and then places the bundled steel bar frame inside the lower mold 41, ensuring that the distance between the two ends of the steel bar frame and the adjacent side sealing plate 4 is the same. Then, the pouring pipe in the concrete pouring equipment is inserted through the pouring hole 5 on one side sealing plate 4 and the pouring pipe is conveyed into the gap inside the lower mold 41 until the outlet of the pouring pipe is close to the other side sealing plate 4. Then the concrete pouring equipment is started, and the concrete is transported to the lower mold 41 through the pouring pipe and fills the inside of the steel frame until the inside of the steel frame in this section is filled with concrete. After the section is filled, the pouring pipe is pulled towards the pouring hole 5, and then this cycle is repeated until the inside of the steel frame is filled. Then the pouring pipe is pulled out, and the sealing block 6 is inserted into the pouring hole 5. The sealing plate 7 is fixedly connected to the outside of the side sealing plate 4 with bolts. The operator then lifts the upper mold 42 with a hoisting device and moves it closer to the top of the lower mold 41. The end of the upper mold 42 fits against the opposite side of the side sealing plate 4 of the lower mold 41, ensuring that the upper mold 42 and the lower mold 41 fit together. During this process, the wedge-shaped slider 438 that is slidably connected to the lower mold 41 will enter the connecting groove 435 opened on the upper mold 42. Since the width of the opening of the connecting groove 435 opened at the bottom of the upper mold 42 is greater than the thickness of the wedge-shaped slider 438, the wedge-shaped slider 438 can enter the connecting groove 435 more easily. As the upper mold 42 continues to move downward, the wedge-shaped slider 438 will first be pressed down along the connecting groove 435 on the lower mold 41, and then simultaneously squeeze the stabilizing slide bar 434 inside the connecting groove 435 to move away from the receiving ring 43, thereby driving the connecting ring 432, which is fixedly connected to the stabilizing slide bar 434, to move together. When the upper mold 42 and the lower mold 41 are fully fitted together, the end of the connecting ring 432 near the drive mechanism 2 will fit against the adjacent receiving ring 43. At the same time, the annular groove 44 on the connecting ring 432 will be sleeved on the outside of the elliptical lower pressure roller 32. When the drive mechanism 2 drives the connected roller 31 to rotate, the roller 31 will rotate against the receiving ring 43, and the receiving ring 43 will drive the upper mold 42 and the lower mold 41 to rotate, thereby realizing centrifugal operation. During this period, the long shaft end of the elliptical lower pressure roller 32 will intermittently fit against the inner wall of the annular groove 44 when rotating, thereby limiting the jumping of the connecting ring 432. This prevents the upper and lower molds 41 from jumping during centrifugal operation, which could cause the concrete inside the mold to crack or fail to form due to vibration. At the same time, since there is no limiting structure between the mold and the support mechanism, this setting can also prevent the mold from detaching from the support of the roller 31 during rotation, thereby reducing the number of defective products, improving the yield, increasing production efficiency, and saving production costs. During the centrifugation stage, the equipment uses the elliptical lower pressure roller 32 to flexibly limit the annular groove 44, ensuring that the mold maintains stable coaxial rotation. This avoids the impact on motor load and sudden power surge caused by eccentricity, allowing the drive mechanism 2 to operate under more stable conditions and effectively reducing the unit energy consumption during the centrifugation stage. At the same time, the stable centrifugation state shortens the ineffective operating time required to reach the specified density, reducing unnecessary energy consumption and thus improving the energy utilization efficiency of the entire production line.

[0030] Simultaneously, during the merging of the upper mold 42 and the lower mold 41, as they approach each other, the docking support rod 467 will first pass through the rectangular groove 465 and continue to move upward. During this period, as the molds approach each other, the connecting ring 432 will also move towards the adjacent receiving ring 43, thereby pushing the support slide rod 46 towards the direction of the drive mechanism 2. Before the upper mold 42 and the lower mold 41 are fully fitted, the end of the sleeve rod 461 first fits against the side of the elliptical limiting block 468. However, since the distance between the bottom of the elliptical limiting block 468 and the top of the rectangular groove 465 is less than the thickness of the sleeve rod 461, the sleeve rod 461 is still abutted by the elliptical limiting block 468. During this process, the support slide rod 46 gradually inserts into the receiving groove, and at the same time, the support slide rod 46 compresses the relief spring 464. As the upper mold 42 and lower mold 41 continue to approach each other, the gap between the bottom of the elliptical limiting block 468 and the top of the rectangular groove 465 will gradually increase until the upper mold 42 and lower mold 41 are completely fitted together. At this point, the gap between the bottom of the elliptical limiting block 468 and the bottom of the rectangular groove 465 will reach its maximum, and the gap will be the same as the thickness of the sleeve rod 461. At this time, due to the elastic force of the relief spring 464, the sleeve rod 461 will be pushed and slid into the gap between the bottom of the elliptical limiting block 468 and the top of the rectangular groove 465, so that the connecting support rod can be connected. 467 is located inside the groove 466 and acts as a gasket. When the sleeve rod 461 slides between the bottom end of the elliptical limiting block 468 and the top end of the rectangular groove 465, the limiting block 4683 and the limiting groove 4671 are in an engaged state. Therefore, when the top surface of the sleeve rod 461 contacts the bottom surface of the elliptical limiting block 468, the elliptical limiting block 468 will not rotate due to the friction of the sleeve rod 461, so that the elliptical limiting block 468 enters the groove 466 and the sleeve rod 461 loses its limiting effect on the elliptical limiting block 468. Since the length direction of the elliptical limiting block 468 in the initial state is parallel to the width direction of the lower mold 41, and the major axis of the elliptical limiting block 468 is greater than the width of the groove 466, the elliptical limiting block 468 will be limited by the sleeve rod 461, so that the upper mold 42 and the lower mold 41 can achieve self-locking. This self-locking method, compared to the traditional bolt fixing method, is more labor-saving during the fixing stage, greatly reduces the intervention time of operators, improves efficiency, and makes the docking process between the upper mold 42 and the lower mold 41 more convenient and faster. During demolding, the operator needs to push the elliptical limit block 468 first, so that the limit block 4683 disengages from the limit groove 4671, so that the limit groove 4671 loses its limit on the elliptical limit block 468, allowing the elliptical limit block 468 to rotate. At this time, the limit shaft 4672 slides to the other end of the relief top groove 4681, and the docking support rod 467 slides to the other end of the relief bottom groove 4682. Twist the elliptical limit block 468 again to rotate it 90 degrees, so that its length direction is parallel to the length direction of the lower mold 41. At this time, the upper mold 42 is lifted by the lifting equipment. The elliptical limit block 468 will pass directly through the groove 466 and the rectangular groove 465. At the same time, as the upper mold 42 moves upward, the reset spring will pull the extension block 439 to move upward along the reset slide 436, thereby driving the wedge slider 438 to move upward. At this time, the stabilizing slide bar 434, which is not interfered by the wedge slider 438, will be pulled by the contraction spring to move away from the drive mechanism 2, thereby making the connecting ring 432 away from the drive mechanism 2, thereby making the annular groove 44 disengage from the elliptical lower pressure roller 32, so that the lower mold 41 can move from the support and lifting mechanism without restriction. This makes the mold's self-locking and anti-jumping all triggered by the merging of the mold, making the whole process simpler and less labor-intensive. The entire operation process, through the coordinated operation of three functions, can comprehensively improve the overall efficiency of pipe pile production. In the mold closing stage, the docking guidance mechanism can achieve rapid and accurate alignment of the upper and lower molds 41, avoiding the tedious operation of repeated adjustments in the traditional mold closing process, significantly shortening the mold closing preparation time, reducing mold edge wear caused by alignment deviation, and extending the service life of the mold. The self-locking function, which is automatically triggered after mold closing, eliminates the need for operators to perform tedious procedures such as bolt tightening, and can directly achieve stable mold locking, effectively reducing the labor intensity of operators. At the same time, it avoids gaps in the mold closing caused by bolt loosening or uneven tightening force, ensuring the sealing of the pipe pile. In the centrifugal operation stage, the anti-jump function can dynamically limit the axial and radial runout of the mold, avoiding quality problems such as internal cracks and uneven density of concrete caused by vibration. It also prevents the production safety hazards caused by the mold detaching from the support structure, reducing the additional costs of rework of defective products and equipment maintenance. The entire process requires no additional manual operation steps, and all functions are automatically triggered and implemented as the operation progresses, significantly improving the overall operating efficiency of the production line and effectively reducing the comprehensive operating costs of pipe pile production. This production process significantly reduces the environmental impact of the entire production process through functional optimization, offering multiple environmental benefits. In terms of resource conservation, the docking guidance function enables precise mold alignment, reduces mold friction wear, extends mold life, and lowers the consumption rate of raw materials such as steel. The anti-jump function improves the pass rate of finished pipe piles, significantly reduces the generation of defective products, avoids the ineffective waste of building materials such as concrete and steel bars, and reduces solid waste emissions generated during the disposal of unqualified products. In terms of pollutant emission reduction, the self-locking function enables automatic mold locking, eliminates mold gaps, avoids cement slurry splashing during centrifugal operation, reduces dust and liquid waste generation at the production site, and reduces the impact of dust emissions on the surrounding air quality. The improved mold sealing also reduces steam leakage during curing, reducing water consumption and total wastewater discharge.

[0031] In terms of energy conservation and consumption reduction, this equipment, through the synergistic effect of the anti-jump mechanism and the self-locking mechanism, enables centrifugal operation to be carried out under stable and low-impact conditions. The motor does not need to frequently overcome the additional resistance caused by jumping, which significantly reduces the ineffective power consumption of the drive system. The docking guidance function reduces repeated adjustments and mold friction wear during the mold closing process, which indirectly reduces the energy consumption of auxiliary processes. In addition, the high yield rate directly avoids the repeated energy consumption of unqualified pipe piles in the mixing, centrifugation, and steam curing stages, realizing energy saving throughout the entire process from mold closing and centrifugation to curing, which is in line with the green and low-carbon manufacturing development direction.

[0032] The embodiments of this example have been described above. However, this example is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this example, and all of them are within the protection scope of this example.
