Description
Technical Field
[0001] This invention relates to the field of wind power construction technology, specifically a wind power concrete tower mold. Background Technology
[0002] A wind turbine concrete tower mold is a specialized piece of equipment used to manufacture wind turbine tower structures. Typically, wind turbine towers are formed by pouring concrete. To ensure the geometric accuracy, dimensional precision, and overall structural strength of the tower, a dedicated mold is essential for the pouring and curing process. However, in current pouring techniques, vibration is usually achieved solely through a vibrating motor mounted on the outer mold surface, resulting in insufficient vibration of the concrete near the inner mold. This insufficient or uneven vibration can easily lead to problems such as concrete segregation or aggregate separation, thus affecting the quality of the concrete tower's formation. Summary of the Invention
[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a wind power concrete tower mold.

A support plate is provided at the bottom of the inner mold, and a vibration component is provided on the support plate. The vibration component generates vibration by contacting the inner mold.
[0005] Compared with the prior art, the beneficial effects of the present invention are: This invention involves installing a vibration motor on the outer mold and adding a vibration component inside the inner mold. The vibration motor transmits power to the outer mold, vibrating the concrete between the outer and inner molds. The vibration component impacts the inner mold, generating vibration, which in turn vibrates the poured concrete. This ensures that the poured concrete is sufficiently vibrated, effectively releasing air bubbles inside the concrete, reducing porosity, and increasing the density of the concrete.

Detailed Implementation
[0014] The present invention will be further illustrated below with reference to specific embodiments. The purpose of this illustration is solely to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.
[0015] A wind power concrete tower mold consists of a base 1, a base 101, an inner mold 201, and an outer mold 102. The base 101 is fixedly connected to the base 1 by bolts 109. The inner mold 201 is placed inside the outer mold 102, and the bottoms of the outer mold 102 and the inner mold 201 are fixedly connected to the base 101 respectively.
[0016] A support plate 202 is fixedly installed at the bottom of the inner ring of the inner mold 201. A vibration component is provided on the support plate 202. The vibration component generates vibration by contacting the inner mold 201, which in turn vibrates the concrete between the inner mold 201 and the outer mold 102.
[0017] Specifically, a square plate 211 is provided on the support plate 202, and the four corners of the square plate 211 are connected to the support plate 202 through connecting columns 203. The vibration assembly consists of a rotary motor 204 and an impact rod. The rotary motor 204 is mounted on the support plate 202 and positioned below the square plate 211. A disc 205 is fixedly connected to the output end of the rotary motor 204. A circular block 206 is fixedly connected to the upper surface of the disc 205 at a position off-center from the center of the disc 205. A slot adapted to the disc 205 is opened on the square plate 211, and the disc 205 is placed in the slot and rotatably connected to the square plate 211.
[0018] To reduce friction between the disc 205 and the square plate 211, a number of balls are arranged circumferentially on the inner wall of the groove. The outer edge of the disc 205 contacts the balls, thereby enabling the disc 205 and the square plate 211 to roll. In this embodiment, a lubricant can also be applied between the disc 205 and the balls to further reduce friction.
[0019] The impact rod is placed above the square plate 211. The impact rod consists of a spiral rod 207 and long rods 208 placed on both sides of the spiral rod 207. The two long rods 208 are fixedly connected to the spiral rod 207. The round block 206 is placed inside the spiral rod 207 and is movably connected to the spiral rod 207.
[0020] Two guide rings 210 are fixedly connected to both ends of the square plate 211. Two long rods 208 are placed in their respective guide rings 210 and slide relative to the guide rings 210. Under the constraint of the guide rings 210, the impact rods move linearly along the guide rings 210.
[0021] Each long rod 208 has a rubber block 209 connected to the end away from the U-shaped rod 207. When the long rod 208 collides with the inner mold, the rubber block 209 can effectively reduce the impact of the long rod 208 on the inner mold 201 and extend the service life of the inner mold 201 and the long rod 208.
[0022] In this embodiment, support ribs 301 are fixedly installed at the upper and lower ends of the inner mold 201. The support ribs 301 are arranged radially along the inner mold 201. The inner mold 201 is strengthened by the support ribs 301 to prevent deformation of the inner mold 201 during the casting process and to improve the load-bearing capacity of the inner mold 201.
[0023] A number of fixing frames 103 are evenly spaced around the outer circumference of the outer mold 102. The fixing frames 103 are arranged in a ring array on the outer wall of the outer mold 102 to ensure that the external pressure or load on the outer mold 102 is evenly distributed among the multiple fixing frames 103, reduce local concentrated pressure, and prevent the outer mold 102 from deforming or being damaged due to excessive load.
[0024] The outer mold 102 has several support plates 104 evenly spaced around its outer circumference. The support plates 104 are arranged in a ring array on the outer side wall of the outer mold 102, and a vibration motor 105 is installed on each support plate 104. The vibration motor 105 can be a three-phase vibration motor 105, which can generate uniform and stable vibration force. The ring array of vibration motors 105 can generate vibration uniformly and act on the concrete during pouring.
[0025] An operating platform 106 is fixedly connected to the top of the outer mold 102. An entrance is provided on one side of the operating platform 106, and a ladder 107 is provided between the entrance of the operating platform 106 and the base 1, allowing operators to easily access the operating platform 106 via the ladder 107. In this embodiment, each step 108 of the ladder 107 is also provided with several strip grooves or anti-slip mats to increase the surface friction of the steps 108, thereby improving anti-slip performance and ensuring the safety of operators when going up and down the ladder 107.
[0026] It should be noted that handrails, guardrails and other safety measures can also be installed on both sides of the escalator 107 to ensure the safety of workers during the pouring process and further improve the practicality of the structure.
[0027] Working principle: After the outer mold 102 and inner mold 201 are first erected, the fixing frame 103 is placed on the outer side of the outer mold 102 to support and fix it. Supporting ribs 301 are installed inside the inner mold 201 for support. The worker starts the vibration motor 105, which then begins to vibrate and transmits power to the outer mold 102, vibrating the concrete between the outer mold 102 and the inner mold 201. At the same time, the worker starts the rotary motor 204, which drives the disc 205 to rotate, and the circular block 206 rotates against the disc. While 205 is in circular motion, it drives the impact rod to reciprocate horizontally along the limiting ring. This causes the long rods 208 on both sides of the return rod 207 to periodically impact the inner wall of the inner mold 201, further vibrating the concrete between the inner mold 201 and the outer mold 102. This makes the aggregate and cement paste in the concrete more evenly distributed, avoiding aggregate separation or water floating during the pouring process. This maintains the consistency and stability of the concrete, and also helps to make the concrete surface smooth and flat, reducing surface defects, improving pouring efficiency, and saving time.
[0028] This invention uses a fixed frame to support and fix the outer mold. During concrete pouring, a vibration motor is started, and the motor begins to vibrate, transmitting power to the outer mold. This vibrates the concrete between the outer and inner molds, ensuring that the concrete is fully vibrated and compacted, effectively releasing air bubbles, reducing porosity, and increasing density. A rotary motor is started, driving a disc to rotate. The circular block moves in a circular motion under the disc's influence. Since the circular block is movably embedded in the inner wall of the retaining rod, the retaining rod moves under the action of the circular block, and the retaining rod is positioned within the limiting hole. Under the constraint of the formwork, the long rods reciprocate in a straight line along the horizontal direction. The long rods on both sides of the formwork periodically impact the inner wall of the inner mold, further vibrating the poured concrete. The addition of rubber blocks effectively reduces damage to the long rods and the inner mold, thus maintaining the consistency and stability of the concrete. It also helps to make the concrete surface smooth and flat, reducing surface defects, improving pouring efficiency, and saving time. In order to prevent the inner mold from deforming due to the influence of the concrete during the pouring process, support ribs are also provided in the upper and lower parts of the inner mold to effectively support the interior of the inner mold.
[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
