Description

Technical Field

[0001] This invention relates to the field of concrete tower construction technology, specifically a variable diameter concrete tower construction platform. Background Technology

[0002] Concrete wind turbine towers are a crucial component of wind turbine generators. They must withstand high-intensity wind loads while ensuring structural stability and durability. Concrete is a commonly used material for manufacturing wind turbine towers, offering advantages such as high strength, good durability, and ease of construction. Furthermore, fiber reinforcement materials can be added to improve the concrete's toughness and crack resistance. To enhance wind resistance, using steel with higher wind resistance ratings can also be considered to increase the tower's stability.

[0003] However, the construction method of concrete towers is generally to manually build a steel reinforcement layer, then pour concrete into it and install it by hoisting after it has cured. When manually building the steel reinforcement layer, because the height of a single layer is relatively high, workers need to build a construction scaffold of appropriate height and then stand on the scaffold to carry out the construction. Since the size of the tower may vary, the length of the construction platform also varies. Therefore, a fixed length construction scaffold cannot be used multiple times. Since the construction platform needs to be built each time and then dismantled after being built, it is a waste of time and manpower. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a variable-diameter concrete tower construction platform, which facilitates the adjustment and expansion of the platform's length to accommodate the construction of reinforced concrete tower layers with different pipe diameters.

The installation plate is placed below the working platform and is connected to the working platform by a support column. An extension platform is slidably provided on the working platform.

[0006] Compared with the prior art, the beneficial effects of the present invention are: This invention adds sliding extension platforms to both sides of the working platform, which allows the width of the working platform surface to be adjusted at any time according to the diameter of the tower being constructed, thereby increasing the applicability of the working platform and meeting the needs of constructing concrete towers with different pipe diameters.

[0007] As a preferred embodiment, a further technical solution of the present invention is: Preferably, it also includes an adjustment component, which includes a lifting block, a connecting rod, a lead screw, and a drive motor.

[0015] 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.

[0016] A variable diameter concrete tower construction platform consists of a working platform 1, an installation plate 2, and an adjustment component 3. The installation plate 2 is placed below the working platform 1 and is connected to the working platform 1 via a support column 4. Support frames 5 are connected to the left and right ends of the installation plate 2, respectively. Extension platforms 6 are slidably provided at the left and right ends of the working platform 1, respectively.

[0017] The adjustment assembly 3 consists of a lifting block 301, a connecting rod 302, a lead screw 303, and a drive motor 304. The drive motor 304 is fixed to the bottom of the mounting plate 2, and the output end of the drive motor 304 passes through the mounting plate 2 and is rotatably connected to the mounting plate 2. A lead screw 303 is provided between the mounting plate 2 and the working platform 1. The lower end of the lead screw 303 is fixedly connected to the output end of the drive motor 304, and the upper end of the lead screw 303 is rotatably connected to the bottom of the working platform 1.

[0018] The lifting block 301 is placed on the lead screw 303 and threadedly connected to the lead screw 303. A connecting rod 302 is hinged to the left and right sides of the lifting block 301 respectively. The working platform 2 is symmetrically provided with slots 101 on the left and right. Each slot 101 is slidably provided with a locking block 7. The two locking blocks 7 are respectively hinged to the connecting rod 302 on their respective sides.

[0019] Each locking block 7 has an elastic element 8 on its outer side, and the elastic element 8 abuts against the bottom of the extension platform 6. In this embodiment, the elastic element is an elastic steel plate.

[0020] Two fixing rods 9 are symmetrically arranged at the front and rear of the bottom of the work platform 1. The two fixing rods 9 are respectively placed on both sides of the lead screw 303, and the bottom ends of the fixing rods 9 pass through the mounting plate 2 and are placed on the ground. The fixing rods 9 pass through the front and rear ends of the lifting block 301, and the lifting block 301 can rise and fall along the fixing rods 9. The fixing rods 9 can both guide the lifting block 301 and support the work platform 1 as a whole.

[0021] The upper surface of the mounting plate 2 is also provided with protective sleeves 10 corresponding to the two extension platforms 6. The extension platform 6 horizontally penetrates the protective sleeve 10 and is slidably connected to the protective sleeve 10.

[0022] In this embodiment, a square plate 11 is provided between each card block 7 and its corresponding elastic element 8, and the highest point of each elastic element 8 is in contact with the bottom surface of the extension platform 6.

[0023] Support columns 4 are fixed at the four top corners of the mounting plate 2. The two support columns 4 on the left side form a group, and the two support columns 4 on the right side form a group. Guide blocks 13 are fixedly connected to the inner sides of the two support columns 4 in the same group. Guide grooves 14 that are adapted to guide blocks 13 are also opened on the front and rear sides of each square plate 11. The square plate 11 slides along the guide blocks 13 through the cooperation of the guide grooves 14 and the guide blocks 13.

[0024] When using this device, first, the entire device should be firmly placed on a horizontal surface, and the support frame 5 and the fixing rod 9 should be fixed. If it is necessary to extend the support surface of the work platform 1, start the drive motor 304. The output end of the drive motor 304 rotates, which drives the lead screw 303 to rotate, thereby causing the lifting block 301 to rise. When the lifting block 301 rises, the angle of the two connecting rods 302 increases, and the two connecting rods 302 push their respective corresponding locking blocks 7 to move to the left and right ends of the work platform 1. At this time, the extension platform 6 can be pushed out to extend the work platform 1.

[0025] As the two extension platforms 6 move to the left and right, the two locking blocks 7 move synchronously with the square plates 11 that are fixedly connected to them. Then, the highest point of the elastic element 8 will come into contact with the bottom surface of the extension platform 1. While deforming, the elastic element 8 will also provide support for its corresponding extension platform 6, thereby improving the stability of the extension platform 6.

[0026] By setting up adjustment components, the width of the work platform can be easily adjusted, thus allowing the entire device to be used for the construction of concrete pouring layers for concrete towers of different pipe diameters.

[0027] By incorporating elastic components, the extension platform can be supported when it is in the deployed state, further enhancing safety for workers standing on its surface during operation.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
