Description

Technical Field

[0001] This utility model belongs to the field of wind power hybrid tower segment production and processing technology, specifically relating to a production mold for wind power hybrid tower segments. Background Technology

[0002] Wind turbine hybrid tower segment molds are the core production carriers that process raw materials such as concrete and steel bars into arc-shaped components that meet the assembly standards of hybrid towers. Their performance directly determines the dimensional accuracy, surface quality, and structural strength of the segments. Wind turbine hybrid tower concrete sections generally adopt a construction mode of factory prefabrication of arc-shaped segments and on-site splicing and assembly. The segment mold is the key equipment supporting this mode. By accurately replicating the arc contour, wall thickness, and reserved hole positions of the segments, it provides a stable curing and forming space for the concrete, ensuring that each segment accurately matches the tower design requirements. Finally, through processes such as bolt connection and grouting sealing, they are spliced ​​into complete hybrid tower sections.

[0003] However, the sealing end plate of the existing segment mold and the mold body are mostly subject to manual calibration. During the bolt tightening process, uneven force can easily cause local gaps, which may lead to grout leakage during concrete pouring. This can easily cause quality defects such as missing corners at the ends of the segments and deviations in wall thickness. In addition, the existing mold has a large contact area with the segments, and it is necessary to pry or forcibly pull it when demolding, which can easily damage the corners of the segments. Utility Model Content

[0004] The purpose of this utility model is to provide a production mold for wind power hybrid tower segments in order to solve the above problems. The connecting block on the inner mold and the long rod form a multi-point support structure, providing a stable rotation axis for the rotating plate, so that the sealing plate can be flexibly rotated around the long rod. When the mold is closed, the sealing plate can completely cover the end gap between the outer mold and the inner mold, completely blocking the leakage path of grout during concrete pouring, and avoiding defects such as missing corners and insufficient wall thickness at the end of the segments caused by grout leakage.

[0005] This utility model achieves the above objectives through the following technical solutions: A production mold for wind turbine hybrid tower segments includes a base plate, an outer mold fixed on the base plate, and an inner mold connected to the outer mold via a sealing mechanism. The sealing mechanism includes a connecting block, a long rod, and a rotating plate. Several connecting blocks are fixed at equal intervals on the inner mold, a long rod is fixed on the connecting block, a rotating plate is rotatably mounted on the long rod, and a sealing plate is fixedly connected to the rotating plate. The sealing plate abuts against the ends of the outer mold and the inner mold.

[0006] As a preferred embodiment, the sealing plate has several locking blocks fixed to the side wall away from the rotating plate, and the outer mold has several locking rods fixed to it. The locking blocks are fixedly connected to the locking rods by bolts.

[0007] As a preferred embodiment, a molding cavity is provided between the outer mold and the inner mold, and both the outer mold and the inner mold are arranged with an arc surface structure.

[0008] In a preferred embodiment, the rotating plate is rotatably connected to the connecting block, and the locking block is engaged with the locking rod.

[0009] In a preferred embodiment, the sealing plate is rotatably connected to the base plate, and the width of the sealing plate is greater than the width of the molding cavity.

[0010] In a preferred embodiment, the inner mold is fixedly connected to a hook on the side wall away from the outer mold, and the inner mold is slidably connected to the base plate.

[0011] As a preferred embodiment, a reinforcing mechanism is installed on the outer mold and the inner mold. The reinforcing mechanism includes a fixing block and a rotating rod. The top of the outer mold is fixedly connected to the fixing block, and the rotating rod is rotatably installed inside the fixing block. The top of the inner mold is fixedly connected to a retaining seat.

[0012] In a preferred embodiment, the end of the rotating rod away from the fixing block is engaged with the card seat, and the card seat is fixedly connected to the end of the rotating rod by bolts.

[0013] As a preferred embodiment, the reinforcement mechanism further includes a base, a base is fixedly connected to the base plate, a support rod is fixedly installed on the inner mold, and the support rod is slidably connected to the base.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) The base plate of this utility model serves as the bearing foundation of the mold as a whole, providing fixed support for the outer mold. At the same time, through the sliding connection with the inner mold, it ensures the horizontal reference during the installation and adjustment of the inner mold, avoiding the relative displacement of the outer mold and the inner mold due to the unstable foundation. Both the outer mold and the inner mold adopt an arc surface structure design, which precisely fits the arc contour of the wind power hybrid tower segment, so that the forming cavity completely replicates the curvature radius and wall thickness requirements of the segment. The sliding connection between the inner mold and the base plate, together with the hooks on the side wall, allows the inner mold to be directly pulled out horizontally along the base plate during demolding without prying or knocking the mold body, thus avoiding the segment from being damaged at the edges and corners due to uneven force during demolding.

[0015] (2) The connecting blocks fixed at equal intervals on the inner mold of this utility model form a multi-point support structure with the long rod, providing a stable rotation axis for the rotating plate, so that the sealing plate can be flexibly rotated around the long rod. When the mold is closed, the sealing plate can completely cover the end gap between the outer mold and the inner mold, forming a double sealing effect, completely blocking the leakage path of the concrete during pouring, and avoiding defects such as missing corners and insufficient wall thickness at the end of the pipe segment caused by leakage. The clamping rod of the outer mold and the clamping block of the sealing plate are connected by a snap-fit, so that the mold can be quickly aligned and positioned when the mold is closed.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 6 As shown, this embodiment of the utility model provides a production mold for wind power hybrid tower segments, including a base plate 1, on which an outer mold 2 is fixed. The outer mold 2 is bolted to the base plate 1 along a pre-set positioning line. The bolts are tightened diagonally in stages to prevent uneven stress and tilting of the outer mold 2. An inner mold 3 is fixedly connected to a hook 6 on its side wall away from the outer mold 2. The hook 6 is used to hook the inner mold 3 onto the side wall of the inner mold 3 using lifting equipment. The hook 6 provides a dedicated lifting point for the inner mold 3, preventing deformation caused by the direct binding of the mold body with wire rope during lifting. The inner mold 3 is slidably connected to the base plate 1, and the outer mold 2 is connected to the inner mold 3 through a sealing mechanism 5.

[0020] Please see Figures 1 to 6As shown, the sealing mechanism 5 includes a connecting block 501, a long rod 502, and a rotating plate 503. Several connecting blocks 501 are fixed at equal intervals on the inner mold 3. A long rod 502 is fixed on the connecting block 501. A rotating plate 503 is rotatably mounted on the long rod 502. A sealing plate 504 is fixedly connected to the rotating plate 503. The sealing plate 504 abuts against the ends of the outer mold 2 and the inner mold 3. Several locking blocks 506 are fixed to the side wall of the sealing plate 504 away from the rotating plate 503. Several locking rods 505 are fixed on the outer mold 2. The locking blocks 506 are fixedly connected to the locking rods 505 by bolts. Push the sealing plate 504 to precisely engage the locking block 506 on the sealing plate 504 with the locking rod 505 on the outer mold 2, achieving initial positioning. Then, use bolts to fix the locking block 506 and the locking rod 505 together. Tighten the bolts until the sealing plate 504 abuts against the ends of the outer mold 2 and the inner mold 3, thus sealing and locking the forming cavity 4. A forming cavity 4 is provided between the outer mold 2 and the inner mold 3, and both the outer mold 2 and the inner mold 3 are designed with an arc surface structure. The rotating plate 503 is rotatably connected to the connecting block 501, and the locking block 506 and the locking rod... The sealing plate 504 is rotatably connected to the bottom plate 1, and the width of the sealing plate 504 is greater than the width of the molding cavity 4. The rotating plate 503 on the rotating rod 502 is fixed on the connecting block 501. The connecting block 501 is evenly distributed on the side wall of the inner mold 3. The rotating plate 503 drives the sealing plate 504 to rotate around the bottom plate 1 until the sealing plate 504 completely abuts against the ends of the outer mold 2 and the inner mold 3, ensuring that its width completely covers the ends of the molding cavity 4 and avoiding sealing dead corners.

[0021] Please see Figures 1 to 6 As shown, a reinforcing mechanism 7 is installed on the outer mold 2 and the inner mold 3. The reinforcing mechanism 7 includes a fixing block 701 and a rotating rod 702. The top of the outer mold 2 is fixedly connected to the fixing block 701, and the rotating rod 702 is rotatably installed inside the fixing block 701. The top of the inner mold 3 is fixedly connected to a retaining seat 703. By rotating the rotating rod 702 installed inside the fixing block 701 at the top of the outer mold 2, the end of the rotating rod 702 away from the fixing block 701 engages with the retaining seat 703 installed at the top of the inner mold 3. Bolts are passed through the retaining seat 703 and the end of the rotating rod 702 to fix the two together, which helps to resist the expansion stress during casting. 02 One end of the fixed block 701 is engaged with the card seat 703, and the card seat 703 is fixedly connected to the end of the rotating rod 702 by bolts. A base 705 is fixedly connected to the base plate 1, and a support rod 704 is fixedly installed on the inner mold 3. The support rod 704 is slidably connected to the base 705. Adjust the position of the support rod 704 on the inner mold 3 so that the end of the support rod 704 away from the inner mold 3 slides into the base 705 fixed on the base plate 1. The support rod 704 and the base 705 are slidably connected to ensure that the bottom of the inner mold 3 is stably supported. With the top tie, the inner mold 3 can be fixed in both directions.

[0022] In use, this invention first places the base plate 1 horizontally on the production table and calibrates its flatness using a level to ensure the stability of the mold's support foundation. Along the pre-set positioning lines on the base plate 1, the outer mold 2 is fixed to the base plate 1 with bolts. When tightening the bolts, a diagonal, multi-stage tightening method is used to prevent uneven stress and tilting of the outer mold 2. Using a lifting device, hooks 6 are attached to the side wall of the inner mold 3. The hooks 6 provide a dedicated lifting point for the inner mold 3, preventing deformation caused by directly binding the mold body with wire ropes during lifting. The inner mold 3 is then slowly lifted above the base plate 1, aligned with the sliding surface of the base plate 1. The inner mold 3 is slid into the inner side of the outer mold 2 along the track. The position of the inner mold 3 is adjusted to ensure that the width of the molding cavity 4 between the outer mold 2 and the inner mold 3 is uniform. The inner mold 3 is then fixed with a temporary bracket to prevent displacement during subsequent operations. Next, the rotating plate 503 on the long rod 502 is rotated. The long rod 502 is fixed on the connecting block 501, which is equidistantly distributed on the side wall of the inner mold 3. The rotating plate 503 drives the sealing plate 504 to rotate around the bottom plate 1 until the sealing plate 504 completely contacts the ends of the outer mold 2 and the inner mold 3, ensuring that its width completely covers the molding cavity 4. To avoid dead corners in sealing, push the sealing plate 504 so that the locking block 506 on the sealing plate 504 precisely engages with the locking rod 505 on the outer mold 2. After initial positioning, use bolts to fix the locking block 506 and the locking rod 505 together. Tighten the bolts until the sealing plate 504 abuts against the ends of the outer mold 2 and the inner mold 3, thus sealing and locking the molding cavity 4. Rotate the rotating rod 702 installed in the fixing block 701 at the top of the outer mold 2 so that the end of the rotating rod 702 away from the fixing block 701 engages with the locking seat 703 installed at the top of the inner mold 3. Use bolts to secure the connection. The ends of the card holder 703 and the rotating rod 702 are fixed together to resist the expansion stress during pouring. The position of the support rod 704 on the inner mold 3 is adjusted so that the end of the support rod 704 away from the inner mold 3 slides into the base 705 fixed on the bottom plate 1. The support rod 704 and the base 705 are slidably connected to ensure that the bottom of the inner mold 3 is stably supported. With the top tie, the inner mold 3 can be fixed in both directions. Finally, concrete is poured into the sealed and reinforced molding cavity 4. During the pouring process, the vibrating equipment is used to eliminate air bubbles and ensure that the concrete fills the molding cavity 4.
