A semi-automatic mold for opening and closing wind power concrete towers

Abstract

This invention provides a semi-automatic mold for wind power concrete towers, comprising an outer mold and a semi-automatic mold opening and closing device. The overall shape is circular, and the outer mold comprises two vertically arranged semi-circular outer mold modules. This invention offers the following advantages: Rotating the drive turntable drives the drive gear in the traveling mechanism, which in turn drives the driven gear to rotate the rollers along the track. This causes the outer mold to move along the track towards its center, ultimately making close contact with the bottom mold for mold closing. Conversely, it moves along the track away from the outer mold's center for mold opening. The semi-automatic mold opening and closing device achieves semi-automatic mold opening and closing, thereby improving efficiency, reducing labor costs, and lowering safety risks. Furthermore, the simple structural design reduces processing costs and ease of use.

Description

Technical Field

[0001] This invention is a semi-automatic mold for opening and closing wind power concrete towers, belonging to the field of construction equipment. Background Technology

[0002] As wind turbine generators become larger and taller, the tower (concrete-steel composite tower), a crucial component of wind turbine generators, is also becoming increasingly larger. The concrete sections of the tower are mostly prefabricated in factories and assembled on-site. Traditional mold assembly and demolding processes are cumbersome, often requiring the assistance of cranes, resulting in low construction efficiency. Furthermore, due to their large size and weight, the molds are highly susceptible to collisions and deformation during operation, and there is even a risk of them falling and injuring people.

[0003] However, while vertical molds, as an alternative to traditional molds, can overcome the problems existing in the manufacturing process of towers, current technology still requires a large amount of manpower to push and pull to perform mold opening and closing actions. This significantly impacts the efficiency and effectiveness of mold opening and closing in the use of large-sized molds today. Furthermore, the complex structure and high precision requirements of vertical molds lead to high processing costs, which contradicts the factory prefabrication and efficient assembly concepts advocated by prefabricated buildings and fails to meet the low-carbon requirements of green building processes. Therefore, there is a current need for a concrete tower mold that is simple in structure, easy to use, and has low processing costs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a semi-automatic mold for opening and closing wind power concrete towers.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] A semi-automatic mold for wind power concrete towers includes an outer formwork and a semi-automatic mold opening and closing device. The overall shape is circular. The outer formwork comprises two vertically arranged semi-circular outer formwork modules. The semi-automatic mold opening and closing device is connected to the outer formwork. The semi-automatic mold opening device includes a ring beam, a support beam, a traveling device, and a track. The ring beam is positioned on the outside of the outer formwork and includes a first ring beam and a second ring beam. The support beam is fixedly positioned on the outside of the ring beam and vertically connected to the first and second ring beams. The traveling device includes a drive turntable, a transmission sprocket set, and rollers. The transmission sprocket set includes a drive gear, a transmission chain, and a driven gear. The support beam is axially connected to the drive gear and the driven gear along the directions of the first and second ring beams, respectively. The drive gear and the driven gear are meshed with the transmission chain. The drive turntable is concentrically fixedly connected to the drive gear, and the rollers are concentrically fixedly connected to the driven gear. The track is located below the traveling device and is parallel to the axis of symmetry of the semi-circular outer formwork. The rollers roll along the track.

[0007] Furthermore, a bottom mold is connected to the inner side of the bottom of the outer template, and an inner mold is also provided on the inner side of the outer template. The bottom mold is annular, and the inner mold is circular. The bottom of the inner mold is fixedly connected to the bottom mold. The outer template, the bottom mold, and the inner mold together form a casting cavity.

[0008] Furthermore, the top of the outer template is uniformly arranged with an integrally fixed outer adjustment support, and the top of the inner template is provided with an integrally fixed inner adjustment support corresponding to the outer adjustment support. Each outer adjustment support is hinged with an adjustment screw rod, and each adjustment screw rod is equipped with two adjustment sleeves that are threaded to it. The adjustment sleeves rotate in opposite directions. The adjustment screw rod is also fitted with a U-shaped clamp between the two adjustment sleeves. The bottom of the outer template, bottom template and inner template is provided with multiple positioning holes along the circumferential direction. Each positioning hole is equipped with a fixing screw rod, which passes through the inner template, bottom template and outer template in sequence. The fixing screw rod is also equipped with a nut.

[0009] Furthermore, a central column is provided at the inner center of the inner mold, and multiple sleeves are fitted on the outer surface of the central column. Support rods connect the sleeves and the inner mold.

[0010] Furthermore, the track and central column are both installed on the construction platform. The construction platform is also equipped with an external reinforcement component surrounding the track. The external reinforcement component includes a drive ring that is rotatably mounted on the construction platform. An inner ring is provided inside the drive ring. An arc-shaped connecting plate is rotatably connected to the drive ring. A triangular plate is rotatably connected to the other end of the arc-shaped connecting plate. One end of the triangular plate is rotatably connected to the top of the inner ring. A reinforcement component is also fixed to the top of the triangular plate. Multiple T-shaped columns are fixed to the top of both the drive ring and the inner ring. Circular holes for the T-shaped columns to pass through are opened on the triangular plate and the arc-shaped connecting plate.

[0011] Furthermore, the reinforcement components include a fixing post fixed to the top of the triangular plate, a reinforcement plate facing outwards on the fixing post, and multiple support posts fixed to the bottom of the inner ring. Corresponding installation threaded holes are opened on the support posts, the inner ring, and the construction platform.

[0012] Furthermore, the construction platform and the drive ring are provided with matching support components. The support components include multiple arc-shaped grooves opened on the construction platform. Multiple secondary fixing columns corresponding to the arc-shaped grooves are fixed at the bottom of the drive ring. I-shaped columns are fixed at the bottom of the secondary fixing columns. The I-shaped columns are slidably set in the corresponding arc-shaped grooves. Sliding balls are embedded in the I-shaped columns. Three-quarters of the volume of the sliding balls is embedded in the I-shaped columns.

[0013] Furthermore, a drive motor is fixedly installed on the construction platform, and a gear is connected to the output end of the drive motor. The outer side of the drive ring is engraved with the meshing teeth of the meshing gear.

[0014] Furthermore, vibrators are installed on the topmost reinforcing plates on the fixed columns, and multiple transverse plates are fixed on the outer side wall of the central column, with auxiliary vibrators installed on the transverse plates.

[0015] Furthermore, a transverse connecting plate is fixedly provided on the outer wall of each auxiliary fixed column, and a threaded rod is threaded on the transverse connecting plate, with a manual turntable fixed at the top of the threaded rod.

[0016] The beneficial effects of this invention are:

[0017] The inner and outer formwork are concentrically set as two circular structures, and the space between them forms a ring-shaped concrete pouring area. The bottom formwork is set at the bottom of this concrete pouring area and is in sealed contact with the inner and outer formwork to form the concrete pouring area together.

[0018] The inner mold is supported by a central column located at its center and supported by a support rod to prevent it from collapsing inward due to concrete pressure. The support rod also serves to erect a construction platform, which supports the entire mold and the central column. The hoop beam is located outside the outer mold and is used to fasten the outer mold to prevent it from expanding outward due to concrete pressure. It also serves to connect to the semi-automatic opening and closing mold mechanism.

[0019] The drive turntable rotates, which in turn drives the drive gear in the traveling assembly. Through the transmission chain, the driven gear drives the roller to roll along the track, thereby moving the outer formwork along the track. The outer formwork moves towards its center along the track until it comes into close contact with the bottom formwork, thus completing the mold closing operation. It then moves away from the center of the outer formwork along the track, completing the mold opening operation. The concrete tower mold, equipped with a semi-automatic mold opening and closing device, achieves semi-automatic mold opening and closing, thereby improving efficiency, reducing labor costs, and lowering safety risks. Simultaneously, the simple structural design reduces the processing cost and ease of use of the mold, aligning with the standardized and industrialized production model of prefabricated buildings. The efficient production of prefabricated components improves the construction efficiency of wind power projects, and the semi-automated operation reduces energy consumption and manual intervention, conforming to the energy-saving, environmentally friendly, and sustainable development concepts advocated by green buildings.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0034] Please see Figure 1-7This invention provides a technical solution: a semi-automatic mold for wind power concrete towers, comprising an outer formwork 100 and a semi-automatic mold opening and closing device, the overall shape being circular. The outer formwork 100 includes two vertically arranged semi-circular outer formwork modules. The semi-automatic mold opening and closing device is connected to the outer formwork. The semi-automatic mold opening device includes a hoop beam 210, a support beam 220, a traveling device 230, and a track 240. The hoop beam 210 is hooped around the outside of the outer formwork 100, and includes a first hoop beam 211 and a second hoop beam 212. The support beam 220 is fixedly arranged around the outside of the hoop beam 210 and vertically connected to the first hoop beam 211 and the second hoop beam 212. The traveling device 230 includes a drive... The device includes a turntable 231, a transmission sprocket assembly 232, and rollers 233. The transmission sprocket assembly 232 includes a drive gear 2321, a transmission chain 2323, and a driven gear 2322. The support beam 220 is axially connected to the drive gear 2321 and the driven gear 2322 along the directions of the first ring beam 211 and the second ring beam 212, respectively. The drive gear 2321 and the driven gear 2322 are meshed with the transmission chain 2323. The drive turntable 231 is concentrically and fixedly connected to the drive gear 2321, and the rollers 233 are concentrically and fixedly connected to the driven gear 2322. The track 240 is set at the lower part of the traveling device 230 and is parallel to the axis of symmetry of the semi-circular outer template 100. The rollers 233 roll along the track 240.

[0035] See Figure 1-7 The bottom inner side of the outer template 100 is connected to the bottom mold 300, and the inner mold 400 is also provided inside the outer template 100. The bottom mold 300 is annular, and the inner mold 400 is circular. The bottom of the inner mold 400 is fixedly connected to the bottom mold 300. The outer template 100, the bottom mold 300, and the inner mold 400 enclose and form a casting cavity. The top of the outer template 100 is evenly distributed with external adjusting supports 110 fixed as one piece. The top of the inner mold 400 is provided with an internal adjusting support 410 fixed as one piece and corresponding to the external adjusting support 110. Each external adjusting support 110 is hinged with an adjusting screw rod 810, and each adjusting screw rod 810 is equipped with two An adjusting sleeve with a threaded engagement is provided, with the adjusting sleeves rotating in opposite directions. A U-shaped clamp is also fitted on the adjusting screw 810 between the two adjusting sleeves. Multiple positioning holes are provided along the circumferential direction at the bottom of the outer template 100, bottom template 300, and inner template 400. Each positioning hole is equipped with a fixing screw 820. The fixing screw 820 passes through the inner template 400, bottom template 300, and outer template 100 in sequence. A nut is also provided on the fixing screw 820. A central column 700 is provided at the inner center of the inner template 400. Multiple sleeves are fitted on the outer surface of the central column 700. A support rod is connected between the sleeves and the inner template 400.

[0036] The inner mold 400 and the outer mold 100 are concentrically arranged as two circular structures, forming a ring-shaped concrete pouring area. The bottom mold 300 is placed at the bottom of this concrete pouring area and is in sealed contact with the inner mold 400 and the outer mold 100, together forming the concrete pouring area. Both the inner mold 400 and the outer mold 100 are formed by the butt joint of curved plates. Numerous reinforcing ribs are provided on the inner surface of the inner mold 400 and the outer surface of the outer mold 100 to provide rigidity for the inner and outer molds. The central column 700 is located at the center of the inner mold 400 and supports the inner mold through support rods to prevent it from collapsing inward due to concrete pressure. It also serves as a construction platform, which supports the entire mold and the central column 700. The ring beam 210 is located outside the outer formwork 100 and is used to fasten the outer formwork to prevent it from expanding outward due to concrete pressure. It also connects to the semi-automatic opening and closing mechanism. The outer formwork 100 includes two semi-circular outer formwork modules. Each outer formwork 100 has a first ring beam 211 and a second ring beam 212 connected from top to bottom to the outer side of the semi-automatic opening and closing mechanism. The traveling device 230 is connected to the ring beam 210 via a support beam 220. Rotating the drive turntable 231 drives the drive gear 2321 in the traveling device 230, which in turn drives the driven gear 2322 to drive the roller 233 along the track 240, thereby moving the outer formwork 100 along the track 240. 240 moves towards the center of the outer mold template, eventually making close contact with the bottom mold to perform the mold closing operation. It then moves along the track away from the center of the outer mold to perform the mold opening operation. After mold closing, the top of the outer mold template 100 and the top of the inner mold 400 are arranged circumferentially with multiple corresponding outer adjusting supports 110 and inner adjusting supports 410. The inner adjusting support 410 is a plate fixed to the top of the inner mold 400. Each outer adjusting support 110 is hinged to an adjusting screw 810. Each adjusting screw 810 is equipped with two adjusting sleeves that match its thread and rotate in opposite directions. After the outer mold template reaches the mold closing state, the adjusting screws 810 are rotated sequentially to engage with the corresponding inner adjusting support 410 of the inner mold 400. The U-shaped clamp fits perfectly onto the inner adjusting support 410. Tightening the adjusting sleeve locks the U-shaped clamp onto the inner adjusting support 410. When mold opening is required, the adjusting sleeve is loosened and the adjusting screw 810 is rotated in reverse to open the inner adjusting support, allowing the outer template 100 to move away from the inner mold and perform the mold opening operation. After the outer template 100 moves to the closed state, the fixing screw 820 is passed through the positioning holes of the inner mold 400, bottom mold 300, and outer template 100 in the circumferential direction. Tightening the nut locks the positions of the inner mold, bottom mold, and outer template. When mold opening is required, the nut is loosened and the fixing screw 820 is passed through the outer template, bottom mold, and inner mold in sequence, allowing the outer template to move away from the inner mold and perform the mold opening operation.

[0037] See Figure 8 and Figure 9The track 240 and the central column 700 are both installed on the construction platform 9. The construction platform 9 is also equipped with an external reinforcement assembly surrounding the track 240. The external reinforcement assembly includes a drive ring 10 rotatably mounted on the construction platform 9, an inner ring 11 inside the drive ring 10, an arc-shaped connecting plate 12 rotatably connected to the drive ring 10, and a triangular plate 13 rotatably connected to the other end of the arc-shaped connecting plate 12. One end of the triangular plate 13 is rotatably connected to the top of the inner ring 11, and a reinforcement member 14 is fixedly mounted on the top of the triangular plate 13. T-shaped columns 22 are fixedly mounted on the top of the drive ring 10, the inner ring 11, and the triangular plate 13. Circular holes for the T-shaped columns 22 to pass through are opened on the triangular plate 13 and the arc-shaped connecting plate 12. The mold is supported on the construction platform 9, and the construction platform 9 is equipped with an external reinforcement assembly surrounding the mold. The reinforcing component mainly consists of a drive ring 10, an inner ring 11, and components mounted on it. The inner ring 11 surrounds the outer ring of the mold. Therefore, the external reinforcing component is not mounted on the mold but is separately designed on the construction platform 9 to reduce mold production efficiency. The mold can still be produced according to the shape set in this application. When the mold is closed, the external reinforcing component is opened. The external reinforcing component provides better support to the outside of the outer template, further preventing outward expansion due to concrete pressure and ensuring better concrete molding effect. The connection between the drive ring 10, inner ring 11, triangular plate 13, and arc-shaped connecting plate 12 is through the open circular hole and T-shaped column 22, which are mutually penetrating, thus ensuring the rotational flexibility of the drive ring 10, inner ring 11, triangular plate 13, and arc-shaped connecting plate 12.

[0038] See Figure 8 The reinforcement component 14 includes a fixing post 15 fixed to the top of the triangular plate 13. A reinforcing plate 16 facing the outer template 100 is fixed on the fixing post 15. Multiple support posts 17 are fixed at the bottom of the inner ring 11. Corresponding installation threaded holes 18 are opened on the support posts 17, the inner ring 11, and the construction platform 9. The main purpose is to bring the fixing post 15 and the reinforcing plate 16 together inward. Therefore, the reinforcing plate 16 moves towards the outer template and finally abuts against the outside of the outer template to reinforce the outer template.

[0039] See Figure 8-10The construction platform 9 and the drive ring 10 are provided with mutually matching support components. The support components include multiple arc-shaped grooves 19 formed on the construction platform 9. Multiple auxiliary fixing posts corresponding to the arc-shaped grooves 19 are fixed to the bottom of the drive ring 10. I-shaped posts 20 are fixed to the bottom of the auxiliary fixing posts. The I-shaped posts 20 are slidably disposed within the corresponding arc-shaped grooves 19. Sliding balls 21 are embedded in the I-shaped posts 20, with three-quarters of their volume embedded in the I-shaped posts 20. A drive motor 23 is also fixed to the construction platform 9. A gear 24 is connected to the output end of the drive motor 23. The outer side of the drive ring 10 is engraved with meshing teeth of the gear 24. Turning on the drive motor 23 causes the gear 24 to rotate. The drive motor 23 is a forward / reverse type motor. The gear 24… The drive ring 10 is meshed with the drive ring 10, so the drive ring 10 rotates. The arc-shaped connecting plate 12 connected to the drive ring 10 moves. When the arc-shaped connecting plate 12 moves, it drives the multiple triangular plates 13 connected to the inner ring 11 to expand or converge on the top surface. Therefore, the fixed column 15 on the triangular plate 13 converges towards the outer template. Finally, the reinforcing plate 16 on the fixed column 15 abuts against the outer side of the outer template to reinforce the outer template. When the drive ring 10 rotates, the I-shaped column 20 moves in the arc-shaped slide groove 19. The ball bearings on the I-shaped column 20 not only provide support, but also allow the I-shaped column 20 to slide in the arc-shaped slide groove 19. The ball bearings greatly reduce the sliding friction, making the movement more effortless and stable.

[0040] See Figure 8 and Figure 11 Vibrators are installed on the topmost reinforcing plate 16 located on the fixed column 15. Multiple transverse plates 25 are also fixed to the outer wall of the central column 700, with auxiliary vibrators installed on each transverse plate 25. During demolding, the vibrators and auxiliary vibrators are installed. The vibrator heads contact the outer side of the outer mold plate, and the auxiliary vibrator heads contact the inner side of the inner mold 400, vibrating during continued demolding to ensure smoother demolding and significantly increase demolding efficiency. Figure 11 The central pillar on top is only made into horizontal plate 25, and other design components are also made.

[0041] See Figure 10 A transverse connecting plate 26 is fixedly installed on the outer wall of the auxiliary fixed column. A threaded rod 27 is threaded on the transverse connecting plate 26. A manual turntable is fixed at the top of the threaded rod 27. The threaded rod 27 is manually rotated so that the bottom of the threaded rod 27 is tightly pressed against the top surface of the construction platform 9, thus completing the further subsequent fixing of the drive ring 10.

[0042] In practice, the inner mold 400 and the outer mold 100 are concentrically arranged as two circular structures, forming a ring-shaped concrete pouring area. The bottom mold 300 is placed at the bottom of this concrete pouring area and is in sealed contact with the inner mold 400 and the outer mold 100, together forming the concrete pouring area. Both the inner mold 400 and the outer mold 100 are formed by the butt joint of curved plates. Numerous reinforcing ribs are provided on the inner surface of the inner mold 400 and the outer surface of the outer mold 100 to provide rigidity for the inner and outer molds. The central column 700 is located at the center of the inner mold 400 and supports the inner mold with support rods to prevent it from collapsing inward due to concrete pressure. It also serves as a construction platform, which supports the entire mold and the central column 700. The ring beam 210, located outside the outer formwork 100, provides support and secures the outer formwork, preventing outward expansion due to concrete pressure. It also connects to the semi-automatic opening and closing mechanism. The outer formwork 100 comprises two semi-circular outer formwork modules. Each outer formwork 100 is connected from top to bottom to the first ring beam 211 and the second ring beam 212 of the semi-automatic opening and closing mechanism. The traveling device 230 is connected to the ring beam 210 via a support beam 220. Rotating the drive turntable 231 drives the drive gear 2321 in the traveling device 230, which in turn drives the driven gear 2322 to rotate the roller 233 along the track 240. This causes the outer formwork 100 to move along the track 240. 240 moves towards the center of the outer mold template, eventually making close contact with the bottom mold to perform the mold closing operation. It then moves along the track away from the center of the outer mold to perform the mold opening operation. After mold closing, the top of the outer mold template 100 and the top of the inner mold 400 are arranged circumferentially with multiple corresponding outer adjusting supports 110 and inner adjusting supports 410. The inner adjusting support 410 is a plate fixed to the top of the inner mold 400. Each outer adjusting support 110 is hinged to an adjusting screw 810. Each adjusting screw 810 is equipped with two adjusting sleeves that match its thread and rotate in opposite directions. After the outer mold template reaches the mold closing state, the adjusting screws 810 are rotated sequentially to engage with the corresponding inner adjusting support 410 of the inner mold 400, thus securing the adjusting sleeves. The tube locks the inner adjusting support 410. When it is necessary to open the mold, the inner adjusting support is opened by loosening the adjusting sleeve and rotating the adjusting screw 810 in reverse order, so that the outer template 100 can move away from the inner template and the mold opening operation can be carried out. After the outer template 100 moves to the closed state, the fixing screw 820 is passed through the positioning holes of the inner template 400, the bottom template 300 and the outer template 100 in the circumferential direction. The nuts are tightened to lock the positions of the inner template, the bottom template and the outer template. When it is necessary to open the mold, the nuts are loosened and the fixing screw 820 is passed through the outer template, the bottom template and the inner template in sequence, so that the outer template can move away from the inner template and the mold opening operation can be carried out. In order to facilitate the operation, a ladder for construction workers to climb onto the operating platform is erected outside the construction platform 9.

[0043] 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. 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.
