Description

Technical Field

[0001] This utility model belongs to the field of wind turbine tower mold technology, specifically relating to a wind turbine hybrid tower mold with a multi-curved composite structure. Background Technology

[0002] As a clean energy source, wind power generation has seen a gradual increase in the height of wind turbine towers in recent years due to the development of onshore wind farms. Concrete wind turbine towers are assembled from precast concrete components. These components are assembled using two templates and then poured with concrete. To improve construction efficiency, the concrete tower sections are often prefabricated in factories and assembled on-site. Furthermore, for ease of transportation, they are often produced in sections.

[0003] The prior art patent publication number CN220313653U describes a mold for manufacturing a wind power concrete tower. This patent includes a fixing component, which comprises multiple mounting blocks, a connecting groove connected to any one of the mounting blocks, a first connecting member connected to the front end of the mounting block, a second connecting member connected to the left end of the first connecting member, a fixing block connected to the upper ends of the first and second connecting members, bolt holes on any one of the fixing blocks, a fixing bolt connected to the right end of the right-end fixing block, and a nut connected to the left end of the left-end fixing block. This device, with its fixing component, ensures a tighter connection between adjacent outer mold blocks, effectively preventing slippage when the connection is not tight, resulting in a more aesthetically pleasing concrete tower after molding. However, in practical use, it still has the following shortcomings: In practice, workers must climb a ladder to the top of the mold and then walk on top to perform the pouring operation, which is very inconvenient, especially when the top of the tower mold is narrow or unstable, posing a safety hazard. Furthermore, manual vibration is required after the concrete is poured into the mold, which is labor-intensive and affects work efficiency.

[0004] Therefore, a multi-curved composite structure wind turbine tower mold is needed to solve the problems of safety hazards caused by workers walking on top of the mold and high labor intensity and low efficiency of manual vibration in the existing technology. Utility Model Content

[0005] The purpose of this invention is to provide a wind power hybrid tower mold with a multi-curved composite structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wind power hybrid tower mold with a multi-curved composite structure, including a base plate, a bottom mold fixedly connected to the bottom of the base plate, an outer mold fixedly installed near the front end of the top of the bottom mold, an inner mold fixedly installed near the rear end of the top of the bottom mold, side molds fixedly installed on both sides of the bottom mold, a top mold fixedly installed on the top of the outer mold, the inner mold and the side molds, a multiple reinforcing ribs fixedly connected to the front end of the outer mold, a multiple reinforcing columns fixedly connected to the rear end of the inner mold, a ladder fixedly connected to the outer side of one of the side molds, a platform moving mechanism provided near the top end of the rear end of the inner mold, and a multiple vibration mechanism provided near the middle end of the rear end of the inner mold.

[0007] It should be noted in the solution that the multiple reinforcing ribs are distributed in a staggered manner in the horizontal and vertical directions at the front end of the outer mold, and the bottom of the multiple reinforcing columns is fixedly connected to the top of the base plate.

[0008] It is further worth noting that the shifting platform mechanism includes multiple fixed seats fixedly connected to both sides of the rear end of the inner mold. An arc-shaped sliding rod is fixedly connected between each pair of corresponding fixed seats. Two first connecting plates are slidably connected to the outer walls of two arc-shaped sliding rods, and two second connecting plates are slidably connected to the outer walls of the other two arc-shaped sliding rods. An operating platform is fixedly connected to the rear end of the two second connecting plates. Multiple vertical rods are fixedly connected to the top of the operating platform. A barrier is fixedly connected to each of the multiple vertical rods near the top. A movable door is rotatably installed on the outer side of one of the barriers. An arc-shaped rack is fixedly connected to the rear end of the inner mold. An L-shaped support plate is fixedly connected to the front end of the operating platform. A first servo motor is fixedly connected to the lower top surface of the L-shaped support plate. A gear is fixedly connected to the output end of the first servo motor.

[0009] It should be further noted that the rear ends of both first connecting plates are fixedly connected to the front end of the fence.

[0010] In a preferred embodiment, the gear meshes with an arc rack.

[0011] In a preferred embodiment, the vibration mechanism includes a concave frame fixedly connected to the rear end of the inner mold. A support plate is fixedly connected between the inner walls of the two sides of the concave frame. Two round rods are slidably connected inside the support plate. A vibration head is fixedly connected to the front end of each of the two round rods. A disc is fixedly connected to the rear end of each of the two round rods. A spring is sleeved on the outer wall of each of the two round rods. A stop ball is fixedly connected to the rear end of each of the two discs. A rotating shaft is rotatably connected between the inner walls of the two sides of the concave frame near the rear end. Two cams are fixedly connected to the outer wall of the rotating shaft. A second servo motor corresponding to the rotating shaft is fixedly connected to the outer side of the concave frame.

[0012] In a preferred embodiment, both springs are fixedly connected between the rear end of the support plate and the front end of the disc.

[0013] In a preferred embodiment, both the outer wall of the vibrating head and the outer wall of the ball retainer are fixedly connected with protective sleeves.

[0014] Compared with the prior art, the multi-curved composite structure wind power hybrid tower mold provided by this utility model has at least the following beneficial effects:

[0015] (1) By setting up a platform moving mechanism, the staff enters the operating platform through the ladder, and then turns on the first servo motor to drive the gear to rotate. Under the action of the arc rack, a counter-thrust force is generated on the operating platform, which causes the operating platform to move. The staff can move inside the operating platform to carry out the operation, avoiding the staff from walking on the top of the mold to carry out the pouring operation. This allows the staff to flexibly adjust the working position and greatly reduces the safety risk of the staff working at height.

[0016] (2) By setting up multiple vibration mechanisms, during the concrete pouring process, the second servo motor is turned on to drive the rotating shaft to rotate, so that the two cams intermittently strike the two stop balls, thereby causing the two round rods to drive the vibrating head to move intermittently. The vibrating head automatically strikes and vibrates the inner mold, replacing the traditional manual vibration, greatly improving the construction efficiency, ensuring that the vibrating head vibrates stably and evenly, greatly improving the density and overall quality of the concrete, and reducing the formation of air bubbles and voids.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please see Figure 1-5 This utility model provides a wind power hybrid tower mold with a multi-curved composite structure, including a base plate 1, a bottom mold 2 fixedly connected to the bottom of the base plate 1, an outer mold 3 fixedly installed near the front end of the top of the bottom mold 2, an inner mold 4 fixedly installed near the rear end of the top of the bottom mold 2, side molds 5 fixedly installed on both sides of the bottom mold 2, a top mold 6 fixedly installed on the top of the outer mold 3, the inner mold 4 and the side molds 5, a plurality of reinforcing ribs 7 fixedly connected to the front end of the outer mold 3, a plurality of reinforcing columns 8 fixedly connected to the rear end of the inner mold 4, a ladder 9 fixedly connected to the outer side of one of the side molds 5, a platform moving mechanism 10 set near the top end of the rear end of the inner mold 4, and a plurality of vibration mechanisms 11 set near the middle end of the rear end of the inner mold 4.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the multiple reinforcing ribs 7 are distributed horizontally and vertically at the front end of the outer mold 3, which can effectively improve the structural strength of the mold and reduce the deformation or displacement of the outer mold 3 due to uneven stress during concrete pouring and vibration. The staggered distribution can evenly distribute the stress, avoid excessive local stress on the mold, and ensure the overall stability and durability of the mold. The bottoms of the multiple reinforcing columns 8 are all fixedly connected to the top of the base plate 1, making the entire frame structure of the mold more robust. By strengthening the bottom connection, it can withstand greater external pressure, ensuring that the mold does not deform, thereby improving the safety during the pouring process.

[0026] Further as Figure 4As shown, it is worth noting that the shifting mechanism 10 includes multiple fixed seats 1001 fixedly connected to both sides of the rear end of the inner mold 4. An arc-shaped sliding rod 1002 is fixedly connected between each pair of corresponding fixed seats 1001. Two first connecting plates 1003 are slidably connected to the outer walls of two arc-shaped sliding rods 1002, and two second connecting plates 1004 are slidably connected to the outer walls of the other two arc-shaped sliding rods 1002. An operating platform 1005 is fixedly connected to the rear end of the two second connecting plates 1004. Multiple vertical rods 1006 are fixedly connected to the top of the operating platform 1005, and a retaining wall 10 is fixedly connected between the multiple vertical rods 1006 near the top. 07, one of the enclosures 1007 has a movable door 1008 rotatably installed on the outside, the inner mold 4 has an arc rack 1009 fixedly connected to the rear end, the operating platform 1005 has an L-shaped support plate 1010 fixedly connected to the front end, the L-shaped support plate 1010 has a first servo motor 1011 fixedly connected to the top lower surface, and the output end of the first servo motor 1011 has a gear 1012 fixedly connected. By setting the platform shifting mechanism 10, the workers can move inside the operating platform 1005 to perform operations, avoiding the workers from walking on the top of the mold to perform pouring operations, so that the workers can flexibly adjust their working positions, greatly reducing the safety risks of workers working at heights.

[0027] Further as Figure 4 As shown, it is worth noting that the rear ends of both first connecting plates 1003 are fixedly connected to the front end of the enclosure 1007. The two first connecting plates 1003 and the two second connecting plates 1004 limit the enclosure 1007 and the operating platform 1005, making their movement on the outer wall of the two arc-shaped sliding rods 1002 more stable, avoiding excessive displacement or asymmetrical movement of the components, reducing the risk of accidents, and ensuring the safety of the operators.

[0028] Further as Figure 4 As shown, it is worth noting that the gear 1012 meshes with the rack 1009, providing precise transmission control. The gear 1012 transmission ensures the smooth movement of the operating table 1005 and the enclosure 1007, reducing positional errors and unstable movements.

[0029] As can be seen from the above working process: by setting up the platform shifting mechanism 10, the staff enters the operating platform 1005 through the escalator 9, and then turns on the first servo motor 1011 to drive the gear 1012 to rotate. Under the action of the arc rack 1009, a counter-thrust force is generated on the operating platform 1005, thereby causing the operating platform 1005 to move. The staff can move and work inside the operating platform 1005, avoiding the staff from walking on the top of the mold to carry out the pouring operation. This allows the staff to flexibly adjust their working position and greatly reduces the safety risks of the staff working at height.

[0030] Further as Figure 5As shown, it is worth noting that the vibration mechanism 11 includes a concave frame 1101 fixedly connected to the rear end of the inner mold 4. A support plate 1102 is fixedly connected between the inner walls of both sides of the concave frame 1101. Two round rods 1103 are slidably connected inside the support plate 1102. Vibration heads 1104 are fixedly connected to the front ends of the two round rods 1103. Discs 1105 are fixedly connected to the rear ends of both round rods 1103. Springs 1106 are sleeved on the outer walls of both round rods 1103. Ball bearings 1107 are fixedly connected to the rear ends of both discs 1105. The two concave frames 1101... A rotating shaft 1108 is rotatably connected between the inner side walls near the rear end. Two cams 1109 are fixedly connected to the outer wall of the rotating shaft 1108. A second servo motor 1110 corresponding to the rotating shaft 1108 is fixedly connected to the outer side of the concave frame 1101. By setting up the vibration mechanism 11, the vibrating head 1104 automatically impacts and vibrates the inner mold 4, replacing the traditional manual vibration, greatly improving construction efficiency. It can ensure that the vibrating head 1104 vibrates stably and evenly, greatly improving the density and overall quality of concrete, and reducing the formation of air bubbles and voids.

[0031] Further as Figure 5 As shown, it is worth noting that both springs 1106 are fixedly connected between the rear end of the support plate 1102 and the front end of the disc 1105, allowing the two round rods 1103 to slide flexibly. The springs 1106 can adjust their own pressure according to changes in external load, thereby providing appropriate restoring force to the round rods 1103 and ensuring that they can return to the predetermined position after movement.

[0032] Further as Figure 5 As shown, it is worth noting that both the outer wall of the vibratory head 1104 and the outer wall of the ball stop 1107 are fixedly connected with protective sleeves. The protective sleeves can effectively reduce the damage caused by external physical impacts to the surface of the vibratory head 1104 and the ball stop 1107, and extend the service life of these components.

[0033] The working process of this solution is as follows: In actual use, the staff enters the operating platform 1005 through the escalator 9 to carry out the pouring work. When it is necessary to move, the first servo motor 1011 is turned on to drive the gear 1012 to rotate. Under the action of the arc rack 1009, a counter-thrust force is generated on the operating platform 1005, thereby moving the operating platform 1005. The staff moves inside the operating platform 1005. At the same time as pouring, the second servo motor 1110 is turned on to drive the rotating shaft 1108 to rotate, so that the two cams 1109 intermittently strike the two stop balls 1107, thereby causing the two round rods 1103 to drive the vibrating head 1104 to move intermittently. The vibrating head 1104 automatically strikes and vibrates the inner mold 4.

[0034] In summary: By setting up the platform shifting mechanism 10, workers can move within the operating platform 1005, avoiding the need for workers to walk on top of the mold during pouring operations. This allows workers to flexibly adjust their working positions and greatly reduces the safety risks associated with working at heights. By setting up the vibration mechanism 11, the vibration head 1104 automatically impacts and vibrates the inner mold 4, replacing traditional manual vibration. This significantly improves construction efficiency, ensures stable and uniform vibration of the vibration head 1104, greatly enhances the density and overall quality of the concrete, and reduces the formation of air bubbles and voids.
