[0024] A method for using a concrete pipe pile rapid prototyping combined mold comprises the following steps:

[0025] S1, end cover one-time connection:

[0026] Install end covers at both ends of the steel cage, place the two sets of end covers on a set of outer molds at the bottom, and connect the two sets of end covers to the mounting holes on the two sets of connecting fan-shaped plates respectively by bolts;

[0027] S2. Concrete pouring:

[0028] The concrete for producing pipe piles is poured evenly into the steel cage, and the concrete on the surface of the guide plate is cleaned. At the same time, the top set of external molds is suspended through the gantry just above the bottom set of external molds, and the two sets of external molds are aligned up and down;

[0029] S3, traction pre-mold:

[0030] Align the guide plates on the outer mold suspended during S2 and concrete pouring and the guide plates on the bottom outer mold with the traction block, then connect the steel cable to the connection hole B on the traction block, and use the winch to pull so that the two sets of guide plates are placed in the traction groove, and the split block is placed between the two sets of guide plates. At the same time, the gantry slowly lowers the suspended outer mold so that the suspended outer mold contacts the bottom outer mold and the steel cage to generate friction to prevent slippage. The winch is continuously wound up to drive the traction block to move on the guide plate, and the top outer mold is corrected so that the top outer mold and the bottom outer mold are fully aligned. In the process of displacement of the traction block, the split block cleans the concrete on the surface of the guide plate so that the concrete falls into the outer mold;

[0031] S4, traction mold closing:

[0032] After the calibration of the upper and lower outer molds in S3 and the traction pre-molding is completed, the capstan is continuously wound to drive the traction block to move on the guide plate until the traction block is detached from the guide plate, and the locking plate is driven to move to the guide plate through the traction block. When the locking plate is completely moved to the guide plate, the mold closing process is completed;

[0033] S5. Mould closing inspection:

[0034] In S4, when the locking plate is completely displaced to the guide plate during the mold closing, the elastic telescopic positioning component is placed in the positioning groove for locking and positioning, and the positioning rod is completely placed in the locking hole. By touching and directly observing whether the surface of the guide plate is flat, it is judged whether the mold closing is in place. If the surface of the guide plate is flat, the mold closing is in place. If the surface of the guide plate is not flat, the mold closing is not in place. Repeat S3 and S4 until the surface of the guide plate is flat during mold closing.

[0035] S6, secondary connection of end cover:

[0036] If S5, mold closing inspection is in place, the end cover is connected to the connecting sector plate of the top set of outer molds to make the whole body in a sealed state, and the whole body is lifted by the gantry, and the supporting sector plate A is placed on the two sets of running wheels. The two sets of outer molds are rotated to generate centrifugal force for shaping;

[0037] S7, mold separation process:

[0038] The two sets of finalized outer molds are lifted off the running wheels, and the two sets of locking plates are set horizontally. The steel cables are connected to the connection holes A of the locking plates, and the locking plates are pulled by the winch to make the locking plates detach from the two sets of guide plates. When the locking plates are completely detached from the guide plates, the traction blocks are placed on the guide plates, that is, the dividing blocks are placed in the guide slope. Then the winch continues to pull, driving the dividing blocks to move between the two sets of guide plates, so that the upper outer mold is tilted. When the traction blocks are completely detached from the guide plates, the mold separation process is completed.

[0039] As an improvement of the above technical solution, in S4, traction mold closing, before the traction block is detached from the two sets of guide plates, the locking plate is aligned with the two sets of guide plates, and the locking plate is pushed so that the head end of the guide plate is placed in the locking groove for limiting. After that, when the traction block is completely detached from the guide plate, the traction block drives the locking plate to move to perform the locking process.

[0040] As an improvement of the above technical solution, in S4, traction mold closing, when the locking plate is completely displaced to the guide plate, the locking plate slides on the guide plate, causing multiple sets of elastic telescopic positioning components to slide in multiple sets of positioning grooves to generate vibrations, thereby removing bubbles in the concrete in advance and reducing pores. In S7, mold separation processing, the locking plate slides on the guide plate, causing multiple sets of elastic telescopic positioning components to slide in multiple sets of positioning grooves to generate vibrations, thereby reducing the adhesion between the concrete pipe pile and the outer mold.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] The above-mentioned technical scheme has the following technical effects: Optimize the concrete pouring process: The elastic vibration effect of the elastic telescopic positioning component of the mold during the locking process helps to compact the concrete during the pouring process, reduce bubbles and gaps, and thus improve the structural strength and durability of the finished pipe piles; Simplify the operating process: Through the design and synergy of the locking plate and guide plate, and the use of the locking mechanism of the steel cable and winch, the operation process is simple and easy, which reduces the manpower and material resources required in the production process and reduces the difficulty of operation; Improve production efficiency and quality control: The rapid positioning and locking mechanism not only improves the speed of mold assembly, but also ensures the accuracy and stability of mold assembly, thereby improving product consistency and quality control level during the production process.

[0063] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0064] Example:

[0065] like Figure 1-19 As shown, this embodiment proposes a concrete pipe pile rapid prototyping combined mold, including two groups of outer molds 10, the two groups of outer molds 10 are symmetrically arranged up and down, two groups of guide plates 15 are symmetrically arranged on the outer molds 10, and end covers 50 are also arranged at both ends of the outer molds 10, and the end covers 50 are provided with movable openings 51;

[0066] Two groups of locking plates 20 are symmetrically arranged on the two groups of outer molds 10, and the locking plates 20 are connected to the outer mold 10 through the movable opening 51. Multiple groups of elastic telescopic positioning components 40 are arranged on the locking plates 20, and multiple groups of positioning grooves 17 are arranged on the guide plate 15. The number and position of the multiple groups of positioning grooves 17 match the number and position of the elastic telescopic positioning components 40. The locking plates 20 slide on the two groups of contacting guide plates 15 to lock, so that the elastic telescopic positioning components 40 slide and displace in the positioning grooves 17 to generate vibration. The locking plates 20 are also provided with locking grooves 24, and the two groups of guide plates 15 are completely placed in the locking grooves 24, so that the multiple groups of elastic telescopic positioning components 40 are respectively placed in the multiple groups of positioning grooves 17, and the two groups of outer molds 10 are locked again.

[0067] In this embodiment, when producing concrete pipe piles, end covers 50 are installed at both ends of the steel cage, and two groups of end covers 50 are placed on a group of outer molds 10 at the bottom end, and concrete for producing pipe piles is evenly poured into the steel cage, and the concrete on the surface of the guide plate 15 is cleaned, and at the same time, a group of outer molds 10 at the top end is suspended through a gantry just above a group of outer molds 10 at the bottom end, and the two groups of outer molds 10 correspond to each other up and down, and then the locking plate 20 is aligned with the two groups of guide plates 15, and a steel cable is connected to the locking plate 20, and the steel cable is wound up by a winch, so that the locking plate 20 is displaced on the guide plate 15, and the two groups of guide plates 15 are locked by the locking plate 20, and when the locking plate 20 is completely placed on the two groups of guide plates 15, multiple groups of elastic telescopic positioning components 40 are respectively placed in multiple groups of positioning grooves 17, and the two groups of outer molds 10 are locked again, and the locking plate 20 is locked at the same time to prevent the locking plate 20 from slipping on the guide plate 15;

[0068] The above technical solution has the following technical effects: optimize the concrete pouring process: during the locking process, the elastic vibration of the elastic telescopic positioning component 40 of the mold helps to compact the concrete during the pouring process, reduce bubbles and gaps, and prevent concrete from overflowing from the outer mold 10, affecting the subsequent mold closing process, and at the same time, it can also improve the structural strength and durability of the finished pipe pile; simplify the operation process: through the design and synergy of the locking plate 20 and the guide plate 15, and the use of the locking mechanism of the steel cable and the winch, the mold closing operation process is simple and easy, reducing the manpower and material resources required in the production process and reducing the difficulty of operation; improve production efficiency and quality control: the rapid positioning and locking mechanism not only improves the mold assembly Speed, also ensure the accuracy and stability of mold assembly, thereby improving product consistency and quality control level during the production process; reduce production costs: due to the efficient assembly and release mechanism of the mold, the production cycle is reduced, the work efficiency is improved, and more products can be produced in a shorter time, reducing the production cost of each unit product; enhance structural stability: through multi-point locking, the connection between the various parts of the mold is more stable, reducing the deformation or displacement of the mold caused by vibration or pressure changes during the production process, thereby ensuring the structural consistency of the finished product, and multiple locking allows for gradual adjustment and refinement of the positioning of the various parts of the mold, ensuring that the components can be accurately aligned, thereby improving the dimensional accuracy of the molded product.

[0069] Specifically, a limiting plate 16 is disposed on the guide plate 15, a limiting groove A25 is provided in the locking groove 24, and the limiting plate 16 is slidably disposed in the limiting groove A25;

[0070] The locking plate 20 is further provided with a plurality of locking holes 22 penetrating therethrough, and a plurality of elastic telescopic positioning components 40 are respectively disposed in the plurality of locking holes 22;

[0071] The guide plate 15 is provided with a sealing groove 19 , and a sealing strip is provided in the sealing groove 19 .

[0072] In this case, a sealing strip needs to be placed in the sealing groove 19 when the mold is closed, and then the two sets of sealing grooves 19 wrap the sealing strip when the mold is closed.

[0073] In this embodiment, the position of the guide plate 15 can be accurately controlled during the sliding process by the cooperation between the limit plate 16 and the limit groove A25, thereby preventing inaccurate mold assembly due to position deviation, thereby ensuring the accuracy and repeatability of mold assembly. The limit plate 16 is slidably arranged in the limit groove A25, which can provide stable support when the mold is locked, preventing the mold from shifting during concrete pouring, and ensuring the stability of the mold and the quality of the final molded product.

[0074] Of course, placing a sealing strip in the sealing groove 19 can improve the overall sealing performance during mold closing.

[0075] Specifically, the locking hole 22 is provided with an active cavity 222;

[0076] The elastic telescopic positioning assembly 40 includes a positioning rod 44, which is slidably arranged in the locking hole 22, and the outer wall of the positioning rod 44 is sleeved with a movable plate 42, and the outer wall of the positioning rod 44 is also sleeved with a return spring 43, and the movable plate 42 and the return spring 43 are arranged in the movable cavity 222, and the return spring 43 is connected between the movable plate 42 and the cavity wall of the movable cavity 222;

[0077] The locking groove 24 is hemispherical, and a hemispherical body 41 is provided at one end of the positioning rod 44 facing the guide plate 15, and the hemispherical body 41 is adapted to the locking groove 24;

[0078] The length of the positioning rod 44 is the same as the depth of the locking hole 22 , and the hemispherical body 41 is placed in the locking groove 24 , so that the positioning rod 44 is completely placed in the locking hole 22 .

[0079] Specifically, an elastic blocking ring 223 is provided in the movable cavity 222, and the elastic blocking ring 223 is fixedly connected to the inner wall of the movable cavity 222, and the movable plate 42 reciprocates and rises and falls to contact with the elastic blocking ring 223 to generate vibration;

[0080] A guide spiral groove 221 is provided on the inner wall of the locking hole 22, and a guide ball 441 is provided on the outer wall of the positioning rod 44. The guide ball 441 is rollingly set on the positioning rod 44, and the guide ball 441 is adapted to the guide spiral groove 221. The guide ball 441 is rollingly set in the guide spiral groove 221, so that the positioning rod 44 can be rotated and reciprocated and lifted.

[0081] In this embodiment, the elastic barrier ring 223 is made of elastic material, and its inner diameter can be deformed and expanded. When the locking plate 20 slides on the guide plate 15, the elastic telescopic positioning assembly 40 contacts the guide plate 15, that is, the hemisphere 41 on the positioning rod 44 contacts the surface of the guide plate 15. At this time, the reset spring 43 is in a compressed state. When the hemisphere 41 passes through the positioning groove 17, the reset spring 43 returns to its original shape, so that the hemisphere 41 collides with the bottom of the positioning groove 17 under elastic potential energy to generate vibration. When the locking plate 20 is completely placed on the guide plate 15, multiple groups of positioning rods 44 are respectively placed in multiple groups of positioning grooves 17, and locked by the reset spring 43 to prevent the locking plate 20 from detaching from the guide plate 15 when the outer mold 10 rotates centrifugally afterwards;

[0082] When the positioning rod 44 hits the bottom of the positioning groove 17 under the action of the return spring 43, the movable plate 42 descends and contacts and hits the elastic blocking ring 223, generating vibration again, and the movable plate 42 makes the positioning rod 44 contact with the bottom of the positioning groove 17 through the elastic blocking ring 223, and in the process of the positioning rod 44 descending, the guide ball 441 rolls in the guide spiral groove 221, and drives the positioning rod 44 to rotate through the guide spiral groove 221, so that the movable plate 42 generates torque to pass through the elastic blocking ring 223 faster, and at the same time, the hemisphere 41 rotates with the rotation of the positioning rod 44. When there are impurities in the positioning groove 17, the surface of the hemisphere 41 and the impurities in the positioning groove 17 rub against each other to crush and crush them, and when the hemisphere 41 leaves the positioning groove 17, the impurities can be taken away from the positioning groove 17, and the friction between the locking plate 20 and the guide plate 15 crushes and crushes the impurities again, so that the block impurities become powder, which is convenient for the locking process;

[0083] The above technical solution has the following effects during actual use: Vibration effect: Vibration is generated through the interaction between the elastic telescopic positioning component 40 and the positioning groove 17, which helps to eliminate bubbles during concrete pouring and improve the density of concrete and the quality of the finished product. The contact and collision between the movable plate 42 and the elastic barrier ring 223 generates a second vibration, which increases the vibration effect and helps to further improve the pouring quality of concrete; Reliable locking: Through the action of the reset spring 43, when the locking plate 20 is completely placed on the guide plate 15, it can ensure that the multiple groups of positioning rods 44 are reliably locked in the multiple groups of positioning grooves 17, so as to prevent the locking plate 20 from being detached during subsequent processes such as centrifugal rotation of the outer mold 10, thereby improving the stability and reliability of the mold; Reducing interference from impurities: The mutual friction between the hemisphere 41 and the positioning groove 17 can crush and pulverize impurities. When the hemisphere 41 is detached from the positioning groove 17, it can also take away the impurities, which helps to maintain the cleanliness of the positioning groove 17 and facilitate the locking process.

[0096] When the locking plate 20 is placed on the guide plate 15, the upper and lower guide plates 15 are aligned first, and the steel cable is connected to the connection hole B33 on the traction block 30, and the winch is used for traction, so that the two guide plates 15 are placed in the traction groove 39, and the dividing block 37 is placed between the two guide plates 15. The top outer mold 10 contacts the bottom outer mold 10 to generate friction to prevent slippage. The winch is continuously wound to drive the traction block 30 to move on the guide plate 15, and the top outer mold 10 is corrected, so that the top outer mold 10 and the bottom outer mold 10 are fully aligned.

[0097] Of course, in this case, the cleaning block 35 is provided with a through hole, and the through hole matches the position of the sealing groove 19, which is used for connecting the sealing strip. During the displacement of the segmentation block 37, the segmentation block 37 drives the cleaning block 35 to slide in the sealing groove 19 to clean the concrete in the sealing groove 19. At the same time, the sealing strip is connected to the through hole. During the displacement of the cleaning block 35, since the cleaning block 35 matches the position of the sealing groove 19, the sealing strip can be filled in the sealing groove 19, which is convenient for the later sealing process.

[0098] During mold separation, the two sets of locking plates 20 are arranged horizontally, and steel cables are connected to the connection holes A23 of the locking plates 20, and the locking plates 20 are pulled by the winch to separate from the two sets of guide plates 15. When the locking plates 20 are completely separated from the guide plates 15, the traction block 30 is placed on the guide plates 15, that is, the segmentation block 37 is placed in the guide ramp 18. Then the winch continues to pull, driving the segmentation block 37 to move between the two sets of guide plates 15, so that the upper outer mold 10 is tilted. Of course, in this step, when the segmentation block 37 is placed between the two sets of outer molds 10, it can be inserted into the guide ramp 18 by means of hydraulic jacking. When the traction block 30 is completely separated from the guide plate 15, the mold separation process is completed.

[0099] Since the length of the traction rod 31 is the same as that of the locking plate 20 , when the traction block 30 is detached from the guide plate 15 , the locking plate 20 can wrap the two sets of guide plates 15 in time, so as to facilitate the locking process.

[0100] A method for using a concrete pipe pile rapid prototyping combined mold comprises the following steps:

[0101] S1, end cover one-time connection:

[0102] Install end covers 50 at both ends of the steel cage, place two sets of end covers 50 on a set of outer molds 10 at the bottom, and connect the two sets of end covers 50 to the mounting holes 14 on the two sets of connecting sector plates 13 respectively by bolts;

[0103] S2. Concrete pouring:

[0104] The concrete for producing the pipe piles is poured evenly into the steel cage, and the concrete on the surface of the guide plate 15 is cleaned. At the same time, the top set of outer molds 10 is suspended directly above the bottom set of outer molds 10 through the gantry, and the two sets of outer molds 10 are aligned up and down;

[0105] S3, traction pre-mold:

[0106] Align the guide plates 15 on the outer mold 10 suspended during S2 concrete pouring and the guide plates 15 on the bottom group of outer molds 10 with the traction block 30, then connect the steel cable to the connection hole B33 on the traction block 30, and use the winch to pull so that the two groups of guide plates 15 are placed in the traction groove 39, and the split block 37 is placed between the two groups of guide plates 15. At the same time, the gantry slowly lowers the suspended outer mold 10, so that the suspended outer mold 10 contacts the bottom outer mold 10 and the steel cage to generate friction to prevent slippage, and the winch is continuously wound to drive the traction block 30 to move on the guide plate 15, and the top outer mold 10 is corrected so that the top outer mold 10 and the bottom outer mold 10 are fully aligned. In the process of displacement of the traction block 30, the split block 37 cleans the concrete on the surface of the guide plate 15 so that the concrete falls into the outer mold 10;

[0107] S4, traction mold closing:

[0108] After the calibration of the upper and lower outer molds 10 in the traction pre-molding is completed in S3, the capstan is continuously wound to drive the traction block 30 to move on the guide plate 15 until the traction block 30 is detached from the guide plate 15, and the locking plate 20 is driven by the traction block 30 to move onto the guide plate 15. When the locking plate 20 is completely moved onto the guide plate 15, the mold closing process is completed;

[0109] S5. Mould closing inspection:

[0110] In S4, when the locking plate 20 is completely displaced onto the guide plate 15 during the pulling mold closing, the elastic telescopic positioning assembly 40 is placed in the positioning groove 17 for locking and positioning, and the positioning rod 44 is completely placed in the locking hole 22. By touching and directly observing whether the surface of the guide plate 15 is flat, it is judged whether the mold closing is in place. If the surface of the guide plate 15 is flat, the mold closing is in place. If the surface of the guide plate 15 is not flat, the mold closing is not in place. Repeat S3 and S4 until the surface of the guide plate 15 is flat during the mold closing.

[0111] S6, secondary connection of end cover:

[0112] If S5, mold closing inspection is in place, the end cover 50 is connected to the connecting sector plate 13 of the top set of outer molds 10, so that the whole is in a sealed state, and the whole is hoisted by the gantry, and the supporting sector plate A11 is placed on the two sets of running wheels, and the two sets of outer molds 10 generate centrifugal force for shaping through the rotation of the running wheels;

[0113] S7, mold separation process:

[0114] The two sets of outer molds 10 after shaping are lifted off the running wheel, and the two sets of locking plates 20 are set horizontally. The steel cables are connected to the connection holes A23 of the locking plates 20, and the locking plates 20 are pulled by the winch to separate from the two sets of guide plates 15. When the locking plates 20 are completely separated from the guide plates 15, the traction blocks 30 are placed on the guide plates 15, that is, the dividing blocks 37 are placed in the guide slope 18. Then the winch continues to pull, driving the dividing blocks 37 to move between the two sets of guide plates 15, so that the upper outer mold 10 is tilted. When the traction blocks 30 are completely separated from the guide plates 15, the mold separation process is completed.

[0115] In this case, the running wheel is the running wheel of a centrifuge. When the running wheel rotates, it drives the mold to rotate to complete the centrifugation process, which will not be described in detail here.

[0116] In this embodiment, in S3, when the segmentation block 37 slides on the guide plate 15 in the traction pre-molding, the segmentation block 37 passes through a position where the two sets of guide plates 15 are in a separated state, so that the outer mold 10 at the upper end is in a tilted state. The tilting of the outer mold 10 at the upper end can provide operators with a larger space to install and adjust internal components, such as a steel cage, an inner mold, etc., thereby improving work efficiency and construction convenience. Moreover, when the outer mold 10 is tilted, the impact or pressure on the internal components placed in the mold or pre-set devices such as prestressed tendons, positioning parts, etc. during the mold closing process can be reduced to prevent damage to these components;

[0117] Of course, in the above steps, during the docking process of the two sets of outer molds 10, compared with the traditional fixation by bolts, on the basis of significantly improving production efficiency, there is no need to manually tighten and loosen the bolts, which can reduce manual labor intensity. At the same time, during the docking process, it is also possible to check whether the molds are accurately docked. In addition, the process of the locking plate 20 being separated from the guide plate 15 can also facilitate the mold separation process. Through mechanized mold separation operations, work efficiency can be significantly improved and work cycles can be shortened, especially in a repetitive production environment.

[0118] Specifically, in S4, traction mold closing, before the traction block 30 is detached from the two groups of guide plates 15, the locking plate 20 is aligned with the two groups of guide plates 15, and the locking plate 20 is pushed so that the head end portion of the guide plate 15 is placed in the locking groove 24 for limiting. After that, when the traction block 30 is completely detached from the guide plate 15, the traction block 30 drives the locking plate 20 to move to perform the locking process.

[0119] In this embodiment, through the above steps, when the traction block 30 is separated from the guide plate 15, the locking plate 20 can be docked on the guide plate 15 in time to avoid deviation after correction and affect the efficiency of mold clamping.

[0120] Specifically, in S4, traction mold closing, when the locking plate 20 is completely displaced onto the guide plate 15, the locking plate 20 slides on the guide plate 15, causing the multiple sets of elastic telescopic positioning components 40 to slide in the multiple sets of positioning grooves 17 and generate vibrations, thereby removing bubbles in the concrete in advance and reducing pores. In S7, mold separation processing, the locking plate 20 slides on the guide plate 15, causing the multiple sets of elastic telescopic positioning components 40 to slide in the multiple sets of positioning grooves 17 and generate vibrations, thereby reducing the adhesion between the concrete pipe pile and the outer mold 10.

[0121] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
