Abstract
Description
Technical Field
[0001] This utility model relates to the field of wind turbine tower casting structure technology, specifically to an assembled protective platform for use inside a wind turbine tower. Background Technology
[0002] During the reinforcement cage binding process before pouring the foundation of the wind turbine tower, a cylindrical area with a diameter of 0.8~1.2m needs to be reserved inside the pouring area. To facilitate the formation of this area, a mold is generally used as a support to position the reinforcement during the binding process and to provide some support during subsequent pouring. Traditional mold structures generally use steel templates or corrugated pipes. However, both steel templates and corrugated pipes need to be commissioned to manufacturers for mold making, but the demand for these molds is small, and ordering them is obviously costly. On the other hand, fixed-size molds are difficult to adapt to the actual needs of non-standard areas. Based on this, it is necessary to design a new protective platform to position the reinforcement during the reinforcement binding process. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an assembled protective platform for use inside wind turbine towers, so as to solve the problem that the current use of steel templates or corrugated pipes as molds in cylindrical areas is costly and difficult to meet the actual use requirements.
[0004] To solve the above problems, this utility model provides the following technical solution:
[0005] An assembled protective platform for use inside a wind turbine tower includes a cylindrical body formed by rolling sheet metal into several loops; a fastening strap is wrapped around the outer surface of the cylindrical body along its circumference; a column is provided in the middle of the inner cavity of the cylindrical body; several sets of support rods are provided on the column; the support rods are cantilevered in the horizontal direction; a top rod is provided on the extended end of the support rod; the top rod is arranged vertically, and one side end of the top rod is supported on the inner wall of the cylindrical body.
[0006] Preferably, the fastening strap is an adjustable-length steel wire cable tie structure.
[0007] Preferably, the column is positioned at the central axis of the cylinder; each set of support rods includes an upper support rod and a lower support rod respectively located on the upper and lower sides of the column; both the upper and lower support rods are sectional telescopic rod structures; a locking device is provided on the upper support rod to restrict its telescopic movement.
[0008] Preferably, there are no fewer than three groups of support rods, and each group of support rods is symmetrically and evenly arranged around the perimeter of the column.
[0009] Preferably, the top rod is an angle steel structure; an arc-shaped rib is installed on the side of the top rod; a strip hole is provided on the arc-shaped rib, the arc-shaped ribs on two adjacent top rods can be stacked and detachably connected by a snap-shaped connector provided at the strip hole; the back end face of the arc-shaped rib is attached to the inner wall of the cylinder.
[0010] Furthermore, the top rod and the arc-shaped rib are detachably installed using snap-fit connections.
[0011] Furthermore, the curved ribs are made of elastic material, and the individual curved ribs at the same height can form a closed ring structure.
[0012] Preferably, a magnetic suction head is installed on the inner side of the cylinder at the position corresponding to the iron plate port.
[0013] The beneficial effects of this utility model are reflected in the following aspects:
[0014] 1. Low cost and easy to obtain: By using rollable sheet metal as the main material of the cylinder, replacing the traditional customized steel template or corrugated pipe, the material cost is greatly reduced. At the same time, it is easy to obtain and process materials on site, which is especially suitable for scenarios with small quantities or non-standard requirements.
[0015] 2. High flexibility and adaptability: The support rod adopts a telescopic structure, and with adjustable length fastening straps, the cylinder diameter can be freely adjusted by adjusting the length of the support rod and the tightness of the straps, adapting to the needs of cylindrical reserved areas of different sizes, effectively solving the usage needs of molds in different environments; at the same time, it simplifies the installation process and shortens the construction cycle.
[0016] 3. High structural stability: The columns and multiple sets of symmetrically distributed support rods form a three-dimensional support system. Combined with the closed ring design of the top rod and elastic arc-shaped ribs, the overall rigidity and deformation resistance of the cylinder are significantly improved, ensuring the stability of the cylinder shape during the reinforcement binding and pouring process and avoiding local collapse.
[0017] 4. Modular assembly and reuse: Each component is assembled by detachable connection methods such as buckles and bolts, which facilitates quick disassembly and transportation. At the same time, it supports partial replacement or adjustment, reducing losses, increasing the reuse rate, and reducing the overall construction cost. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0023] Example:
[0024] Reference Figure 1 This embodiment provides an assembled protective platform for use inside a wind turbine tower. It includes a cylindrical body 1 formed by rolling sheet metal into several loops. Fastening straps 2 are wrapped around the outer side of the body 1 along its circumference. A column 3 is provided in the middle of the inner cavity of the body 1. Several sets of support rods 4 are provided on the column 3. The support rods 4 are cantilevered in the horizontal direction. A top rod 5 is provided on the extended end of the support rod 4. The top rod 5 is arranged vertically, and one side end of the top rod 5 is supported on the inner wall of the body 1.
[0025] The fastening strap 2 is an adjustable-length steel wire cable tie. The pressure applied to the outer periphery of the cylinder can be adjusted by fastening the cable tie.
[0026] The column 3 is positioned at the central axis of the cylinder 1. Each set of support rods 4 includes an upper support rod 41 and a lower support rod 42 respectively positioned on the upper and lower sides of the column 3. Both the upper support rod 41 and the lower support rod 42 are segmented telescopic rod structures. A locking element 43 is provided on the upper support rod 41 to restrict its telescopic movement. In this embodiment, each segment of the upper support rod has a slotted hole, and the locking element 43 is a bolt assembly, which is located at the slotted hole and is locked by bolts to restrict the relative movement between the segments.
[0027] There are no fewer than three sets of support rods 4, and each set of support rods 4 is symmetrically and evenly arranged around the perimeter of the column 3. By adjusting the extension and retraction length of each set of support rods 4, the diameter of the inner side of the cylinder 1 can be adjusted, and the supporting force of the top rod 5 on the inner wall of the cylinder 1 can be changed.
[0028] The top rod 5 is an angle steel structure; an arc-shaped rib plate 6 is installed on the side of the top rod 5; the arc-shaped rib plate 6 has a strip hole; the arc-shaped rib plates 6 on two adjacent top rods 5 can be stacked and detachably connected by a buckle connector provided at the strip hole; the back end face of the arc-shaped rib plate 6 is attached to the inner wall of the cylinder 1.
[0029] The top rod 5 and the arc-shaped rib plate 6 are detachably installed by means of a snap fastener.
[0030] The arc-shaped ribs 6 are made of elastic material, and the individual arc-shaped ribs 6 at the same height can form a closed ring structure. This ring structure allows for the formation of multiple layers of ring-shaped reinforcing ribs within the cylinder 1, significantly improving compressive strength.
[0031] A magnetic suction head is installed on the inner side of the cylinder 1 at the position corresponding to the iron sheet port. The magnetic suction head is a permanent magnet; it uses magnetic attraction to make the iron sheet port stick to the iron sheet on the back side, preventing relative displacement of the iron sheet on the inner side.
