Description

Technical Field

[0001] This utility model relates to a platform structure for storing precast concrete tower segments, belonging to the field of wind power engineering technology. Background Technology

[0002] Currently, wind turbine concrete tower segments (referred to as "hybrid tower segments") adopt a segmented design, where a complete tower ring is produced by dividing it into four different types of segments, which are then assembled into a complete ring for hoisting. This design reduces transportation difficulties, shortens installation time, and improves work efficiency. However, a single wind power project involves dozens of different specifications of hybrid tower segments, totaling over a thousand segments, making the proper stacking and storage of these segments a significant challenge. At present, hybrid tower segments are primarily stacked using sleepers as a support structure, with sleepers placed at the bottom of the segments for support. This support structure requires the sleepers to have sufficient strength and rigidity to withstand the weight of the segments; secondly, the spacing of the sleepers must be rationally set according to the size and weight of the segments, generally placing one sleeper at regular intervals to ensure the segments remain stable during stacking. Thirdly, the height of the sleepers should be consistent to keep the segments horizontal and prevent tilting. The disadvantages are as follows: First, under the long-term heavy pressure of tunnel segments, the sleepers may deform or bend, especially when the segments are stacked high or heavy. Once the sleepers deform, it will affect the stability of the stacked segments, which may lead to the segments tilting or even collapsing. After the sleepers deform, their supporting surface will no longer be flat, which will cause uneven stress on the segments and increase the risk of damage to the segments. Second, the sleepers are susceptible to the effects of environmental factors such as humidity and rain. In a humid environment, the sleepers may absorb moisture and swell and soften, thereby reducing their supporting strength. Long-term exposure to a humid environment may also cause the sleepers to rot, further weakening their supporting capacity. Third, temperature changes will also affect the sleepers. At high temperatures, the sleepers may dry and crack, while at low temperatures, they may become more brittle. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a platform structure for storing precast concrete tower segments, which can effectively solve the problem of concrete segment stacking and reduce the risk of segment tipping.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A platform structure for storing precast concrete tower segments includes a storage platform, on which two rows of fixing slots adapted to the precast tower segments are sequentially opened along its length, and a quality inspection channel is provided between the two rows of fixing slots.

[0006] Furthermore, the two rows of fixing slots are mirror images of the storage platform along its axis in four areas A, B, C, and D of the storage platform, with the fixing slots in each area arranged at equal intervals.

[0007] Furthermore, the opening width of the fixing groove is slightly larger than the bottom width of the mixing tower tube sheet.

[0008] Furthermore, the cross-sectional shape of the fixing groove is arc-shaped, and its projection in the horizontal direction is a 1 / 4 circle.

[0009] Furthermore, the number of fixed slots in each row is 8-10.

[0010] Furthermore, the storage platform is made of cast concrete, and the fixing groove is integrally cast with the storage platform.

[0011] This utility model discloses a platform structure for storing precast concrete tower segments. Concrete casting provides a superior storage solution compared to existing sleeper supports, allowing for the stacking of more, taller, and heavier precast tower segments. The segments are stacked stably without collapsing, and the concrete storage platform is resistant to moisture, does not crack at high temperatures, and remains stable at low temperatures, resulting in a long service life. Furthermore, the storage platform is divided into four areas (A, B, C, and D), each capable of storing different types of precast tower segments, enabling categorized and orderly stacking and improving the efficiency of quality inspection by management personnel.

[0015] The present invention will be described in detail below with reference to specific implementation examples. The following implementation examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way.

[0016] like Figure 1 — Figure 3 As shown, this utility model relates to a platform structure for storing precast concrete tower segments, including a storage platform 1. Two rows of fixing slots 2 adapted to the precast tower segments 4 are sequentially opened on the storage platform 1 along its length direction, and a quality inspection channel 3 is set between the two rows of fixing slots 2.

[0017] Furthermore, the two rows of fixing slots 2 are mirror images of the storage platform 1 in four areas A, B, C, and D of the storage platform 1, with the fixing slots 2 arranged at equal intervals in each area. To store the mixed tower tube segments 4 in a standardized and orderly manner, the four areas of the same storage platform 1 can be divided into four areas, A, B, C, and D, to distribute and store the mixed tower tube segments of four types A, B, C, and D.

[0018] Furthermore, the opening width of the fixing groove 2 is slightly larger than the bottom width of the mixing tower tube 4, which facilitates the insertion of the mixing tower tube into the fixing groove.

[0019] Furthermore, in order to better match the end face of the mixing tower tube 4 and ensure its stability, the cross-sectional shape of the fixing groove 2 is arc-shaped, and its projection in the horizontal direction is a 1 / 4 circle.

[0020] Furthermore, the number of fixed slots 2 in each row is 8-10. The number of fixed slots 2 in each storage platform 1 is preferably 40, that is, 10 fixed slots 2 corresponding to each of the four models A, B, C and D, to ensure that the mixed tower tubes will not be damaged due to mutual collision during the stacking process.

[0021] Furthermore, the storage platform 1 is made of concrete, and the fixing groove 2 is integrally cast with the storage platform 1. The storage platform made of concrete not only has good strength and strong support, but is also easy to manufacture and has low cost.

[0022] In use, storage platforms 1 are arranged sequentially in the segment stacking area. The number of storage platforms 1 can be adjusted according to the size of the segment stacking area. To store mixed tower segments 4 in a standardized and orderly manner, the four areas of the same storage platform can be divided into areas A, B, C, and D to store mixed tower segments of four types: A, B, C, and D. Each sub-area can store 10 mixed tower segments 4, that is, each storage platform 1 can store 10 complete rings of mixed tower segments. A quality inspection channel 3 is left in the middle of the storage platform 1, which allows segment management personnel to inspect the quality of the mixed tower segments. Segment transport vehicles can drive to the vicinity of the segment stacking area, take out the required type of mixed tower segments for the wind turbine location in sequence, and transport them to the splicing area at the wind turbine location to splice them into complete rings.

[0023] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
