Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, specifically to a structure and method for preventing torsion and correcting deviation on a silo slipform platform. Background Technology

[0002] Slipform construction of silos is a common technique for building large silo structures. During the vertical lifting process of the slipform platform, it is prone to twisting and tilting due to factors such as asymmetrical concrete pouring, uneven distribution of construction load, and inconsistent friction of the formwork. If the tilting is not corrected in time and effectively, it will lead to excessive verticality deviation and uneven stress on the structure after the silo is formed, which will seriously affect the construction quality and safety of the silo.

[0003] Patent application CN203441092U discloses a slipform correction device. This device is simple to assemble and quick to construct. It can effectively control the verticality deviation of cast-in-place concrete structures, reduce the post-processing work of building facades, and has significant economic and quality benefits, making it a valuable tool for widespread application.

[0004] Patent application CN115247492B discloses a sliding formwork correction and torsion adjustment device. This device features multiple parallel gantry legs vertically arranged on a plane. The upper and lower crossbeams of the gantry are connected to the upper and lower sides of the gantry legs, respectively. Waler lugs are located at the upper and lower ends of one or both sides of the gantry frame. Steel wire rope chain hoists are fixed to the upper crossbeam of the gantry and the waler lugs of another gantry, thus each gantry has two steel wire rope chain hoists fixed on both sides. This allows for timely, rapid, and accurate correction of platform deformation during sliding formwork construction.

[0005] In the aforementioned patents, the device can achieve a certain degree of slipform correction, but it can only complete single-direction limit correction in most cases. During the continuous lifting of the slipform platform, it cannot coordinate with the lifting action of the platform to complete multi-level limit anti-torsion correction. It lacks positional stability of the main correction structure and is difficult to continuously ensure the overall positional accuracy of the slipform during the lifting process. Torsion and skew problems are still likely to occur, affecting the construction quality of the silo slipform.

[0006] To address the aforementioned issues, there is an urgent need for innovative design based on the existing correction structure. Summary of the Invention

[0007] The purpose of this invention is to provide a structure and method for preventing torsion and deviation correction in silo slipform platforms, in order to solve the problems mentioned in the background art, such as the inability of existing devices to synchronously complete multi-level limiting anti-torsion and deviation correction during the continuous lifting of the slipform platform, insufficient positional stability of the main correction structure, difficulty in continuously ensuring the overall positional accuracy of the slipform during the lifting process, and the tendency for torsion and deviation to occur, thus affecting the construction quality of silo slipforms.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A silo slipform platform anti-torsion and correction structure includes an outer mold and an inner mold disposed inside the outer mold, with lifting components disposed at the upper ends of the outer mold and the inner mold; a correction structure is disposed on the outer side of the outer mold, and the correction structure can control the stable vertical movement of the outer mold and the inner mold; a control structure is disposed on the outer side of the outer mold, and the control structure can further ensure the stable vertical movement of the outer mold and the inner mold; a positioning structure is disposed on the outer side of the outer mold, and the positioning structure can provide a foundation for the stable movement of the outer mold and the inner mold.

[0010] Preferably, the straightening structure includes a fixing member, and two sets of fixing members are fixedly installed on the outside of the outer mold. Two sets of sliding rods are slidably installed inside the fixing member, and a moving part is fixedly installed at the end of the sliding rods near the outer mold. Two sets of vertical rollers are rotatably installed at the end of the moving part near the outer mold.

[0011] Preferably, a moving cylinder is fixedly installed at the end of the moving part away from the outer mold, and a rotating screw installed on the internal thread of the moving cylinder is rotatably connected to the fixed part. A driven gear is fixedly installed at the end of the rotating screw away from the outer mold, and the driven gear meshes with a main gear ring rotatably installed on the outside of the outer mold.

[0012] Preferably, two sets of driven rods are rotatably mounted on the outer side of the moving part, and an arc-shaped part is rotatably mounted on the end of the driven rod near the outer mold, and a driving rod is rotatably mounted between the arc-shaped part and the fixed part.

[0013] Preferably, the control structure includes mounting components, and two sets of mounting components are fixedly mounted on the outside of the outer mold. Two sets of arc-shaped clamping plates are rotatably mounted on the lower end of the mounting components, and a connecting rod is rotatably mounted on the upper end of the arc-shaped clamping plates.

[0014] Preferably, the vertical rod passes through the support fixedly installed on the outside of the outer mold, and a tripod is fixedly installed at the upper end of the vertical rod. A hydraulic rod is fixedly installed between the tripod and the support. The rotating seat rotatably installed at the lower end of the connecting rod is rotatably connected to the arc-shaped clamping plate.

[0015] Preferably, an upper clamping block is fixedly installed on the outer side of the vertical rod, and the lower end of the vertical rod is located on the upper end of the lower clamping piece that is rotatably installed on the outer side of the outer mold. The upper clamping block and the lower clamping piece are located at the upper and lower ends of the main gear ring, respectively.

[0016] Preferably, the positioning structure includes a positioning rod and a tripod, with the positioning rod fixedly installed on the outside of the outer mold and passing through the tripod. Meanwhile, a drive screw is rotatably installed inside the tripod on the side of the tripod closest to the outer mold.

[0017] Preferably, the lifting component, which is threaded on the outside of the drive screw, is slidably connected to the tripod, and the lifting component is provided with an adjusting wheel through a transverse groove opened inside it, and the adjusting wheel is located on the inclined side of the tripod where the tilting component is fixedly installed inside.

[0018] This invention also discloses a method for preventing torsion and correcting deviation on a silo slipform platform, the method comprising the following steps:

[0019] S1: Rotating the main gear ring causes the driven gear to drive the rotating screw to rotate. The moving cylinder outside the rotating screw will drive the vertical roller to contact the outside of the silo. The arc-shaped part will contact the outside of the silo under the action of the driven rod and the driving rod, completing the initial vertical and radial limit, ensuring the accuracy of the movement of the outer mold and the inner mold outside the silo.

[0020] S2: The hydraulic rod drives the tripod to move downwards, which can use the upper clamping block on the outside of the vertical rod to clamp the upper end of the main gear ring. Meanwhile, the vertical rod directly squeezes the lower clamping piece, which rotates to clamp the lower end of the main gear ring, ensuring the stability of the position between the main gear ring and the outer mold. Simultaneously, the vertical rod drives the arc-shaped clamping plate to rotate through the connecting rod and rotating seat and contact the outside of the silo again, thereby completing the vertical and radial limiting of the outer and inner molds, ensuring the smoothness of the rise of the outer and inner molds, and improving the accuracy of the silo construction process.

[0021] S3: Before the tripod moves down, the position of the lifting component can be adjusted by rotating the screw. At this time, the lifting component will drive the adjusting wheel to move through the transverse groove. The adjusting wheel will be affected by the tilting component and move closer to the outside of the outer mold, so that the tripod can be raised and lowered smoothly, providing conditions for the limit of the main gear ring and the arc-shaped clamping plate, and providing a basis for the stable correction of the silo.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This anti-torsion correction structure, through a layered and progressive correction, control and positioning design, can limit and correct the sliding platform in both vertical and radial displacement dimensions throughout the entire process of sliding formwork lifting. Compared with the traditional single-point correction method, it avoids the problem of excessive single correction amplitude affecting the forming accuracy of the silo structure and improves the stability of correction adjustment.

[0024] 2. The design of synchronously driving multiple sets of correction structures through the main gear ring can ensure uniform force on the periphery of the silo, avoid uneven local force which can aggravate platform torsion and displacement, and at the same time, cooperate with the control structure to lock the correction position, further improving the overall stability of the correction structure, reducing the probability of platform torsion and displacement during slipform construction, and effectively improving the accuracy and safety of silo slipform construction.

[0025] 3. Furthermore, the positioning structure can adjust the extension of the adjusting wheel by driving the screw to adapt to the construction size requirements of silos of different specifications. There is no need to replace the adaptable parts for different construction conditions, which improves the applicability of the structure and reduces the supporting modification cost of slipform construction.

[0026] 4. Furthermore, this anti-torsion correction method, through a step-by-step operation process design, first completes the initial limit and then performs the secondary locking and positioning. Each step of the adjustment can be flexibly adjusted according to the offset data monitored in real time. Operators can adjust the correction force at any time according to the progress of slipform lifting, making the operation more flexible and more suitable for the slipform construction needs under complex working conditions.

[0027] 5. Furthermore, the entire correction structure is arranged between the outer side of the silo and the outer mold, which will not occupy the slipform construction space inside the silo or interfere with the construction operations inside the silo. It can be directly installed and used without changing the original slipform construction process, and is compatible with the existing slipform construction system. It does not require significant adjustments to the original construction plan, making the modification and use more convenient. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1: This embodiment is an example Figures 1-3 As shown, the present invention provides the following technical solution: a silo sliding formwork platform anti-torsion and correction structure, the specific contents of which are as follows: including an outer mold 1 and an inner mold 2 set inside the outer mold 1, and a lifting component 3 is provided at the upper end of the outer mold 1 and the inner mold 2;

[0041] The outer mold 1 is provided with a correction structure on its outer side, and the correction structure can control the stable vertical movement of the outer mold 1 and the inner mold 2. The outer mold 1 is provided with a control structure on its outer side, and the control structure can further ensure the stable vertical movement of the outer mold 1 and the inner mold 2. The outer mold 1 is provided with a positioning structure on its outer side, and the positioning structure can provide a basis for the stable movement of the outer mold 1 and the inner mold 2.

[0042] When using the anti-torsion and correction structure of the silo slipform platform, it is necessary to select an appropriate inner mold 2 according to the building specifications of the silo and fix it inside the outer mold 1. Then, the lifting component 3 is lifted by a tower crane (or crane) so that the inner mold 2 is placed outside the ring reinforcement. Concrete is poured into the inner mold 2 and the silo prototype is formed after the concrete solidifies. Then, the lifting component 3 is lifted upwards again and concrete is poured into the inner mold 2 again. This process is repeated to complete the construction of the silo. During this process, it is necessary to ensure that the outer mold 1 and the inner mold 2 move stably in the vertical direction to ensure the verticality and stability of the silo.

[0043] according to Figures 1-2 and Figure 6 As shown, a moving part 7 is fixedly installed with a moving cylinder 9 at the end away from the outer mold 1, and a rotating screw 10 installed on the internal thread of the moving cylinder 9 is rotatably connected to the fixed part 4. A driven gear 11 is fixedly installed at the end of the rotating screw 10 away from the outer mold 1, and the driven gear 11 meshes with the main gear ring 12 rotatably installed on the outside of the outer mold 1.

[0044] After the initial concrete pouring is completed during the silo construction process, the annular concrete poured in the initial pouring is used as a basis for further pouring. After the outer mold 1 is moved upward, the vertical roller 8 needs to contact the outer side of the annular concrete. The accuracy of the upward movement of the outer mold 1 is crucial to avoid any deviation or deflection. During this process, the main gear ring 12 needs to rotate. The rotation of the main gear ring 12 will drive the rotating screw 10 to rotate through the meshing gear 11. The rotation of the rotating screw 10 will directly cause the moving cylinder 9, which is threaded on its outer side, to slide inside the fixed part 4. At the same time, the moving cylinder 9 will drive the moving part 7 to move closer to the solidified concrete.

[0045] according to Figures 1-4 As shown, the correction structure includes a fixing member 4, and two sets of fixing members 4 are fixedly installed on the outside of the outer mold 1. Two sets of sliding rods 5 are slidably installed inside the fixing member 4, and a moving member 7 is fixedly installed at one end of the sliding rods 5 near the outer mold 1. Two sets of vertical rollers 8 are rotatably installed at one end of the moving member 7 near the outer mold 1.

[0046] The moving part 7 will directly cause the two sets of vertical rollers 8 to contact the outside of the concrete, thereby ensuring that the outer mold 1 and the inner mold 2 move vertically on the outside of the already poured concrete, and avoid them from tilting vertically and affecting the effect of the later silo construction.

[0047] according to Figures 1-6 As shown, two sets of driven rods 14 are rotatably mounted on the outer side of the moving part 7, and an arc-shaped part 15 is rotatably mounted on the end of the driven rod 14 near the outer mold 1, and an active rod 13 is rotatably mounted between the arc-shaped part 15 and the fixed part 4.

[0048] Furthermore, during the movement of the moving part 7, it will directly push the arc-shaped part 15 to move through the driven rod 14. The arc-shaped part 15 will also be in contact with the outer side of the concrete under the action of the driving rod 13, thereby radially fixing the outer side of the concrete and preventing the outer mold 1 and the inner mold 2 from rotating in the horizontal plane, thus ensuring the stability of the outer mold 1 and the inner mold 2 during operation.

[0049] according to Figures 1-6 As shown, the vertical rod 20 passes through the support member 21 fixedly installed on the outside of the outer mold 1, and a tripod 23 is fixedly installed at the upper end of the vertical rod 20. A hydraulic rod 22 is fixedly installed between the tripod 23 and the support member 21. The rotating seat 24 rotatably installed at the lower end of the connecting rod 19 is rotatably connected to the arc-shaped clamping plate 18.

[0050] During the movement of the hydraulic rod 22, the tripod 23 will move downwards directly. During the downward movement of the tripod 23, the vertical rod 20 will be pushed down inside the support 21. The downward movement of the vertical rod 20 will cause the two sets of connecting rods 19 and the rotating seat 24 to rotate.

[0051] according to Figures 7-8 As shown, an upper clamping block 25 is fixedly installed on the outer side of the vertical rod 20, and the lower end of the vertical rod 20 is located on the upper end of the lower clamping block 26 rotatably installed on the outer side of the outer mold 1. The upper clamping block 25 and the lower clamping block 26 are located at the upper and lower ends of the main gear ring 12, respectively.

[0052] During the downward movement of the vertical rod 20, the upper clamping block 25 will directly contact the upper end of the main gear ring 12, and the lower end of the vertical rod 20 will squeeze the lower clamping member 26 and cause the lower clamping member 26 to rotate, thereby contacting the lower end of the main gear ring 12. At this time, the upper clamping block 25 and the lower clamping member 26 can clamp and limit the upper and lower ends of the main gear ring 12 respectively, ensuring the stability of the position limit between the main gear ring 12 and the outer mold 1, and avoiding the situation where the main gear ring 12 and the outer mold 1 rotate relative to each other.

[0053] according to Figures 7-8 As shown, the control structure includes a mounting component 17, and two sets of mounting components 17 are fixedly installed on the outside of the outer mold 1. Two sets of arc-shaped clamping plates 18 are rotatably installed on the lower end of the mounting component 17, and a connecting rod 19 is rotatably installed on the upper end of the arc-shaped clamping plates 18.

[0054] During the rotation of the connecting rod 19 and the rotating seat 24, the two sets of arc-shaped clamping plates 18 will move, and the ends of the two sets of arc-shaped clamping plates 18 close to the annular concrete will clamp the annular concrete again, thereby repositioning the outer mold 1 and the silo and ensuring the accuracy of the adjustment of the outer mold 1 and the inner mold 2.

[0055] according to Figures 9-10 As shown, the positioning structure includes a positioning rod 27 and a tripod 23. The positioning rod 27 is fixedly installed on the outside of the outer mold 1 and passes through the tripod 23. Meanwhile, a drive screw 28 is rotatably installed inside the tripod 23 on the side of the tripod 23 closest to the outer mold 1.

[0056] During movement, the tripod 23 will slide on the outside of the positioning rod 27, and the tripod 23 is equipped with a rotatable drive screw 28 inside.

[0057] according to Figures 9-10 As shown, the lifting component 29, which is threaded on the outside of the drive screw 28, is slidably connected to the tripod 23. The lifting component 29 is provided with an adjusting wheel 32 through a transverse groove 30 inside it, and the adjusting wheel 32 is located on the inclined side of the inclined component 31, which is fixedly installed inside the tripod 23.

[0058] During the rotation of the drive screw 28, the lifting component 29 slides up and down inside the tripod 23. The up and down movement of the lifting component 29 drives the adjusting wheel 32 to move through the transverse groove 30. The adjusting wheel 32 moves downward and is squeezed by the tilting component 31 to move closer to the outside of the outer mold 1. At the same time, the adjusting wheel 32 moves laterally inside the transverse groove 30, so that the tripod 23 can move up and down smoothly, providing conditions for the limiting of the main gear ring 12 and the limiting of the arc-shaped clamping plate 18, and ensuring the stability of the structure's correction.

[0059] The present invention also provides a method for preventing torsion and correcting deviation on a silo slipform platform, the method comprising the following steps:

[0060] S1: Rotating the main gear ring 12 causes the driven gear 11 to drive the rotating screw 10 to rotate. The moving cylinder 9 on the outside of the rotating screw 10 will drive the vertical roller 8 to contact the outside of the silo. The arc-shaped part 15 will contact the outside of the silo under the action of the driven rod 14 and the driving rod 13, completing the initial vertical and radial limit, ensuring the accuracy of the movement of the outer mold 1 and the inner mold 2 on the outside of the silo.

[0061] S2: The hydraulic rod 22 drives the tripod 23 to move downward. The upper clamping block 25 on the outside of the vertical rod 20 can clamp the upper end of the main gear ring 12, while the vertical rod 20 directly presses the lower clamping piece 26. The rotation of the lower clamping piece 26 clamps the lower end of the main gear ring 12, ensuring the stability of the position between the main gear ring 12 and the outer mold 1. The vertical rod 20 will simultaneously drive the arc-shaped clamping plate 18 to rotate through the connecting rod 19 and the rotating seat 24 and make contact with the outside of the silo again, thereby completing the vertical and radial limit of the outer mold 1 and the inner mold 2, ensuring the smoothness of the rise of the outer mold 1 and the inner mold 2, and improving the accuracy in the silo construction process.

[0062] S3: Before the tripod 23 moves down, the position of the lifting component 29 can be adjusted by rotating the screw 10. At this time, the lifting component 29 will drive the adjusting wheel 32 to move through the transverse groove 30. The adjusting wheel 32 will be affected by the tilting component 31 and move closer to the outside of the outer mold 1, so that the tripod 23 can be raised and lowered smoothly, providing conditions for the limit of the main gear ring 12 and the arc-shaped clamping plate 18, and providing a basis for the stable correction of the silo.

[0063] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0064] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
