Abstract
Description
Technical Field
[0001] This invention relates to the field of high pier construction technology, specifically a roller formwork device for high pier construction. Background Technology
[0002] The roller formwork construction technology for high piers combines the advantages of flip-form and slipform construction while avoiding the disadvantages of climbing form and flip-form. It employs a hydraulic system for automatic formwork lifting, eliminating the need for disassembly of the formwork and tower crane lifting, resulting in high speed. The inner lining form is separated from the outer frame; the outer frame automatically slides up while the inner lining form is manually flipped up. The inner lining form remains relatively stationary with the concrete surface, improving the concrete appearance quality compared to slipform construction. The formwork is installed in one go, forming a closed system around the pier column and continuing construction to the top. The outer frame operating platform is fully closed and connected. The hydraulic system uses a self-locking lifting system, ensuring significantly higher construction safety compared to conventional methods. This technology ensures both the speed of high pier construction and improves the concrete appearance quality, offering enhanced construction safety compared to flip-form, climbing form, and slipform processes. Therefore, roller formwork construction is currently widely used in high pier construction.
[0003] In existing roller formwork construction processes, concrete debris easily falls between the roller body and the inner lining template and can stick to the roller body. Over time, excessive concrete adhering to the roller body will affect its rolling. Chinese patent (authorization announcement number: CN114960439B) discloses a roller formwork device for high pier construction. This patent includes a roller body, a scraper mechanism, a recycling mechanism, and a striking mechanism. A recycling mechanism is set below the scraper mechanism to collect the scraped concrete, and a striking mechanism is set on the outer frame to shake the concrete out of the scraper mechanism.
[0004] However, the actual implementation of this patent has certain defects. In actual operation, multiple rollers are arranged in parallel around the outer perimeter of the inner lining template. The scraped concrete is subjected to scraping force and vibration force, so it does not fall in a straight line and cannot fall accurately into the bottom recycling mechanism. Instead, it falls into the bottom area of the inner lining template or into the rollers below, resulting in the problem of concrete accumulation below, with a higher thickness, which affects the actual operation. Summary of the Invention
[0005] The purpose of this invention is to provide a roller formwork device for high pier construction to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0011] As a further embodiment of the present invention: the scraper frame includes support wing plates disposed on both sides, a mounting base mounted on the support wing plates, a limiting frame disposed on the mounting base, and a guide frame disposed within the limiting frame; the scraper component includes an inclined frame plate mounted on the leading edge of the guide frame, and a shovel head disposed on the leading edge of the inclined frame plate; the shovel head is tangentially close to the roller surface of the roller body, and the guide frame plate is connected to the rear edge of the limiting frame.
[0012] As a further embodiment of the present invention: the side edge of the supporting wing plate is provided with a pneumatic component, a telescopic rod installed on the pneumatic component, and a mounting block installed on the telescopic rod, wherein the mounting block is fixedly installed with the limiting frame.
[0013] As a further embodiment of the present invention: the tail end of the limiting frame is provided with an installation strip and a connecting block installed on the installation strip; the mounting base is provided with a base point support shaft; the connecting block is installed on the base point support shaft; and a reset torsion spring is wound on the base point support shaft; one end of the reset torsion spring is connected to the mounting base, and the other end is connected to the connecting block.
[0014] As a further embodiment of the present invention: the receiving box includes a side support plate installed on the equipment bracket, a recycling box body installed on the side edge of the side support plate, a receiving port installed on the top of the recycling box body, and a support frame supporting the recycling box body and the side support plate.
[0015] As a further aspect of the present invention: the vibrating component includes an elastic horizontal support disposed between the recycling box and the side support plate. The elastic horizontal support includes a horizontal support rod mounted on the side support plate, a support plate mounted on the horizontal support rod, and a support spring mounted on the support plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are:
[0018] This invention designs the roller to move towards the scraper component, with the scraper component tangentially close to the roller surface. This allows the concrete adhered to the roller surface to come into contact with the scraper component. As the roller rotates, the concrete gains an initial velocity and is separated by the scraper component, falling onto the guide plate within the scraper frame. The concrete then slides along the guide plate into the corresponding receiving box. The separated concrete is then separated from the top of the roller and thrown out, sliding into the corresponding recycling component. This design prevents the concrete from falling into the bottom area of the inner lining template or into the roller below, making the overall construction process of the high-pier roller formwork smoother.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, examples of which are illustrated in the drawings. In the following description relating to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or identical elements.
[0031] Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0032] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.
[0033] In one embodiment, see Figure 1 and Figure 2 A roller formwork device for high pier construction is provided, including a main formwork frame 11, a plurality of equipment supports 12 set on the main formwork frame 11, and a rolling device 13 set on the equipment supports 12;
[0034] The rolling device 13 includes a roller assembly 15 disposed at the front edge of the rolling device 13 and a recovery assembly 14 disposed at the rear edge of the roller assembly 15.
[0035] The roller assembly 15 includes a support frame 21, a roller 22 disposed on the support frame 21, and a scraper frame 23 mounted on the support frame 21. A scraper component 24 is disposed inside the scraper frame 23. The scraper component 24 is obliquely close to the roller surface of the roller 22, and the roller 22 moves toward the side facing the scraper component 24. The recycling assembly 14 includes a receiving box 26 disposed behind the scraper frame 23. A guide plate 25 is disposed along the rear edge of the scraper frame 23. The guide plate 25 is used to connect the receiving box 26 and the scraper component 24. A vibrating component 27 is also disposed along the side edge of the receiving box 26.
[0036] This embodiment is designed based on existing high-pier roller formwork technology. The main mold frame 11 is the main support structure of this embodiment. The main mold frame 11 is installed on the overall climbing track. The lifting and lowering of the main mold frame 11 is controlled by a hydraulic drive structure. Several equipment supports 12 are provided on the main mold frame 11 to support each rolling device 13. The rolling device 13 is located on the outer edge of the concrete high pier. The roller body 22 is attached to the outer surface of the inner lining template 16. The inner lining template 16 is made of a splicable high-molecular polymer material. During operation, the roller body 22 moves towards the side of the scraper 24, that is, in the counterclockwise direction in the figure, scraping the material. The component 24 is tangentially close to the roller surface of the roller body 22, so that the concrete adhered to the roller surface of the roller body 22 comes into contact with the scraper component 24. As the roller body 22 rotates, the concrete gains an initial velocity and is separated by the scraper component 24. It falls onto the guide plate 25 inside the scraper frame 23 and slides down along the guide plate 25 into the corresponding receiving box 26. The separated concrete is separated from the upper position of the roller body 22 and then thrown and slides down into the corresponding recycling component 14. This avoids the concrete falling into the bottom area of the inner lining template 16 or into the roller body below, making the construction process of the overall high pier roller formwork smoother.
[0037] Preferably, the receiving box 26 is also provided with a vibrating component 27 on its side edge, so that the receiving box 26 is subjected to a small amplitude vibration force, which facilitates the falling of concrete and prevents concrete from adhering to the inlet of the receiving box 26.
[0038] In one embodiment, see Figure 2 and Figure 3Based on the above embodiments, the installation structure of the roller body is designed as follows in this embodiment.
[0039] The support frame 21 includes a support outer frame 31, a plurality of horizontal support rails 32 disposed in the support outer frame 31, support bearings 34 disposed on the support outer frame 31 on both sides, and support roller shafts 33 installed between the support bearings 34; the roller body 22 is mounted on the support roller shaft 33, a motor frame 35 is disposed on the side edge of the support outer frame 31, a drive motor 36 is mounted on the motor frame 35, and a transmission wheel 37 is disposed on the drive end of the drive motor 36; a driven wheel 39 is mounted on the shaft end of the support roller shaft 33, and a synchronous belt 38 is disposed between the transmission wheel 37 and the driven wheel 39.
[0040] The support frame 21 is a support structure installed on the equipment support 12. The outer support frame 31 and the horizontal support rail 32 are combined to form the frame structure of the support frame 21. The roller body 22 is installed between the support bearings 34 on both sides. The scraper frame 23 is also installed diagonally above the outer support frame 31. During operation, the drive motor 36 is used as the power source to drive the transmission wheel 37 to move. A synchronous belt 38 is provided between the transmission wheel 37 and the driven wheel 39, so that the roller body 22 can roll in contact with the outer surface of the inner lining template 16.
[0041] In one embodiment, see Figure 2 and Figure 4 Based on the above embodiments, the installation structure of the scraper frame 23 and the scraper component 24 is designed as follows in this embodiment.
[0042] The scraper frame 23 includes support wing plates 41 on both sides, mounting base 42 mounted on the support wing plates 41, limiting frame 43 mounted on the mounting base 42, and guide frame 44 within the limiting frame 43; the scraper component 24 includes an inclined frame plate 45 mounted on the front edge of the guide frame 44, and a shovel head 46 mounted on the front edge of the inclined frame plate 45; the shovel head 46 is tangentially close to the roller surface of the roller body 22, and the guide frame plate 25 is connected to the rear edge of the limiting frame 43.
[0043] The shovel head 46 is tangentially close to the roller surface of the roller body 22. As the roller body 22 rotates counterclockwise, the concrete on the surface of the roller body 22 separates from the surface of the roller body 22. However, during separation, the concrete itself still has an initial velocity that moves synchronously with the roller body 22. Then, it moves along the inclined frame plate 45 to the guide frame 44. The limiting frames 43 on both sides limit the internal space of the guide frame 44. The concrete slides along the guide frame 44 onto the material guide plate 25 and then falls into the receiving box 26.
[0044] In one instance of this embodiment, please refer to Figure 4 and Figure 5 The side edge of the supporting wing plate 41 is provided with a pneumatic component 51, a telescopic rod 52 mounted on the pneumatic component 51, and a mounting block 53 mounted on the telescopic rod 52. The mounting block 53 is fixedly installed with the limiting frame 43. The tail end of the limiting frame 43 is provided with an installation strip 55 and a connecting block 56 mounted on the installation strip 55. The mounting base 42 is provided with a base point support shaft 57. The connecting block 56 is mounted on the base point support shaft 57, and a return torsion spring 58 is wound on the base point support shaft 57. One end of the return torsion spring 58 is connected to the mounting base 42, and the other end is connected to the connecting block 56.
[0045] The pneumatic component 51 is a small hydraulic drive structure, which, together with the telescopic rod 52, forms a small-amplitude telescopic structure. The limiting frame 43, the guide frame 44, and the inclined frame plate 45 are integrated structures, thereby driving the integrated structure to swing slightly around the mounting base 42 as the fulcrum. The mounting base 42 is supported by the base point support shaft 57, on which a return torsion spring 58 is wound. During operation, the telescopic rod 52 pushes the guide frame 44 downward, so that the shovel head 46 moves obliquely downward to remove the concrete adhering to the surface of the roller 22. Due to inertia, the concrete enters the inclined frame plate 45 or the guide frame 44. During the downward movement, the return torsion spring 58 is compressed and twisted. Therefore, during the subsequent return process, the return torsion spring 58 releases elastic potential energy, forming a rapid return movement trend, which then agitates the concrete, allowing the concrete to be smoothly guided to the rear guide frame plate 25, thereby ensuring the smooth transfer of concrete from low to high.
[0046] In one embodiment, see Figure 6 , Figure 7 and Figure 8 Based on the above embodiments, the installation structure of the roller body is designed as follows in this embodiment.
[0047] The receiving box 26 includes a side support plate 61 mounted on the equipment bracket 12, a recycling box body 63 mounted on the side edge of the side support plate 61, a receiving port 62 mounted on the top of the recycling box body 63, and a supporting frame 64 supporting the recycling box body 63 and the side support plate 61. The receiving port 62 is connected to the guide plate 25. The recycling box body 63 is a concrete loading tool. The side support plate 61 supports the receiving box 26 through the supporting frame 64.
[0048] The vibrating component 27 includes an elastic horizontal support 71 disposed between the recycling box 63 and the side support plate 61. The elastic horizontal support 71 includes a horizontal support rod 72 mounted on the side support plate 61, a support plate 74 mounted on the horizontal support rod 72, and a support spring 75 mounted on the support plate 74. The other end of the support spring 75 is connected to the outer wall of the recycling box 63, and the plate end of the outer support frame 64 is connected to the support plate 74 by a fastening bolt 73.
[0049] The vibrating component 27 also includes an outer edge support plate 82 mounted on the recycling box 63, a swing wheel 83 mounted on the outer edge support plate 82, a reversing motor 84 mounted on the side support plate 61, and a reversing wheel 85 mounted on the reversing motor 84. The reversing wheel 85 and the swing wheel 83 are connected by a belt drive component 86.
[0050] In this embodiment, the horizontal support rod 72 provides support to the support plate 74, and the support spring 75 provides elastic support to the recycling box 63 inward. Simultaneously, a reversing motor 84, a micro CNC motor, is installed, which uses a relevant CNC program controller to change direction at a certain angle. In this embodiment, the motor shaft of the reversing motor 84 rotates at a range of 30°. The reversing motor 84 changes direction after rotating 30°, causing the reversing wheel 85 to oscillate back and forth within a 30° angle range. This, in turn, drives the swing wheel 83 to move synchronously, resulting in a slight oscillation of the entire recycling box 63. Combined with the elastic horizontal support 71, which is mainly supported by the support spring 75, this causes the recycling box 63 to bounce slightly. This facilitates the bumping of concrete from the guide plate 25 into the recycling box 63, and also helps the concrete above the inner cavity of the recycling box 63 to be bumped to the bottom, preventing concrete from accumulating and clumping at the receiving port 62.
[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
[0052] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
