Description

Technical Field

[0001] This utility model relates to the field of tower construction technology, and in particular to a concrete tower installation platform. Background Technology

[0002] There are currently two main structural forms for wind turbine towers: all-steel tower structure and steel-concrete tower structure. Both types of towers are tapered structures that are smaller at the top and larger at the bottom.

[0003] During the hoisting and installation of concrete towers, a temporary installation platform is required for each section of the tower to facilitate tasks such as applying adhesive and installing accessories. Since concrete towers are typically tapered structures, wider at the bottom and narrower at the top, most installation platforms are multi-platform designs to accommodate different tower sizes.

[0004] However, since a set of installation and construction platforms includes 4-6 individual installation and construction platforms, in actual use, workers need to spend a lot of manpower on the disassembly and assembly of the installation and construction platforms. At the same time, during the hoisting of the concrete tower, especially during the relocation process, multiple individual installation and construction platforms increase transportation and relocation costs. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned in the background art, such as the need for workers to spend a lot of manpower to disassemble and assemble the existing installation and construction platform, and the high transportation and relocation costs. Therefore, a concrete tower installation and construction platform is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A concrete tower installation platform includes a first platform and a second platform. Both the first and second platforms include an installation platform. The installation platform of the first platform is configured in two separate parts connected by a flange. The installation platform of the second platform is a single unit. Multiple telescopic beams are slidably inserted into the outside of the installation platform. A positioning pin is slidably inserted into one end of the installation platform. Multiple positioning pin holes corresponding to the positioning pins are equidistantly provided on the telescopic beams. Adjacent telescopic beams are connected by multiple step plates. Uprights are fixedly welded to the ends of the multiple telescopic beams away from the installation platform. The multiple uprights are connected by chains.

[0008] Preferably, the number of the plurality of positioning pins is three.

[0009] Preferably, the upright is a 30*30 square tube, and the chain is connected to the upright by a carabiner.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] In this utility model, the construction platform adopts the form of a telescopic beam, which can realize the platform size change of 6.5m diameter. According to actual use experience, this assembled construction platform can be adapted to the construction of wind turbine concrete towers with a height of 140m.

[0012] 2. Due to the adoption of a novel structural form, this utility model reduces the number of installation and construction platforms, manufacturing costs, installation and dismantling workload, transportation costs, and economic benefits. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-2 A concrete tower installation platform includes a first platform and a second platform. Both the first platform and the second platform include an installation platform 1. The installation platform 1 of the first platform is set in two separate parts and the two parts of the installation platform 1 are connected by a flange 2. The installation platform 1 of the second platform is set in one piece.

[0019] In this embodiment, multiple telescopic beams 3 are slidably inserted into the outside of the installation platform 1, and a positioning pin 4 is slidably inserted into one end of the installation platform 1. Multiple positioning pin holes corresponding to the positioning pins 4 are equidistantly arranged on the telescopic beams 3, and the number of multiple positioning pin holes is three.

[0020] In this embodiment, two adjacent telescopic beams 3 are connected by multiple step plates 5, and each of the multiple telescopic beams 3 has a vertical pole 6 fixedly welded to the end away from the installation platform 1;

[0021] In this embodiment, multiple uprights 6 are connected by chains 7. The uprights 6 are 30*30 square tubes, and the chains 7 are connected to the uprights 6 by carabiners 8.

[0022] In this embodiment, refer to Figure 3 The installation process for the construction platform is as follows:

[0023] 1. Select the construction and installation platform according to the tower diameter:

[0024] Based on the diameter variation range of the installation platforms, platform 1 is suitable for concrete towers with an inner diameter of 9320mm to 5420mm, and platform 2 is suitable for concrete towers with an inner diameter of 5320mm to 2820mm, for a total applicable range of concrete tower inner diameter variation of 6500mm. In actual use, the platform to be used should be selected according to the inner diameter of the top opening of the concrete tower.

[0025] 2. Installation of fixed parts of the construction and installation platform

[0026] Based on the dimensions of the fixed parts of the construction and installation platform (for ease of transportation), the fixed part of platform 1 is divided into two parts, connected by flange 2. Before use, the two parts need to be assembled together. Because platform 2 is smaller in size, it is designed as a single unit.

[0027] 3. Installation / Positioning of the Expansion Beam 3 on the Construction and Installation Platform

[0028] The telescopic beam 3 is inserted through the pre-reserved socket on the mounting platform. The telescopic beam 3 has three sets of locating pins to determine the insertion depth. Select the appropriate locating pin according to the actual size requirements and insert the locating pin 4.

[0029]

[0030] 4. Installation of the movable platform panel for construction and installation.

[0031] The platform's movable step treads 5 consist of three layers from the innermost to the outermost, and are available in six different models. The configuration is based on the length of the platform's telescopic beam 3, as shown in the table below:

[0032]

[0033] 5. Installation of the construction platform fence system

[0034] A platform fence is installed around the perimeter of the installation platform to ensure the safety of workers operating on it. Because the installation platform is retractable, the fence is made of flexible material. The fence posts are made of 30*30 square tubing, with posts 6 welded to the outside of the telescopic beam 3. Chains are installed between the posts, and carabiners 8 secure the chains 7 to the rings on the posts 6. The entire fence surrounds the installation platform, forming the installation platform fence system.

[0036] The construction and installation platform is lifted using a tower hoisting main hoist. The lifting points are set on the fixed part of the construction and installation platform, and the attachment lifting points are set on the outside of the telescopic beam 3. The universal rotating side pull lifting ring is screwed into the pre-embedded bolt holes of the tower. Each telescopic beam 3 is equipped with one lifting point.

[0037] 7. Repeat steps 1-6 to complete the use of each tower assembly platform.

[0038] During tower installation, as the tower hoisting height increases, the inner diameter of the tower decreases accordingly. To adapt to the change in tower size, this installation platform adopts a telescopic beam design, which can achieve a platform size change of 6.5m in diameter. Based on actual usage experience, this assembly platform can be used for the construction of wind turbine concrete towers with a height of 140m.

[0039] In this embodiment, the adoption of a novel structural form reduces the number of installation platforms, manufacturing costs, installation and dismantling workload, and transportation costs, thereby increasing economic benefits.
