Technical Field
[0001] This utility model relates to the field of wind turbine tower construction technology, and in particular to a wind turbine tower wall foundation groove template installation and positioning device. Background Technology
[0002] The wind turbine tower wall foundation groove is an important component for the stability of the wind turbine tower foundation. The wind turbine tower wall foundation groove bears the entire load of the wind turbine, hub, and blades and transfers it to the foundation structure layer. In addition, it can also adjust the horizontal displacement and elevation of the wind turbine tower, bear the wind turbine operating load, and ensure the stable and safe operation of the wind turbine. The traditional positioning method of the wind turbine tower wall foundation groove is to fix the groove template with steel bar limiters and steel wires. The groove template is placed directly on the steel bar surface of the column, and steel bar limiters are set around it. Steel wires are used to tie it to the steel bar of the column. The steel bar limiters are prefabricated according to the elevation and geometric dimensions. The steel bar limiters are welded to the top surface of the column's reinforcing steel bars. The steel wires are tied to the groove template and firmly tied to the steel bar limiters to prevent displacement. The construction process is divided into two steps: (1) making steel bar limiters, (2) welding and tying them firmly to the top surface of the column's reinforcing steel bars. This traditional method has the following shortcomings: 1. After the steel bar limiter is made, the steel bar of the pedestal may be displaced by the construction load, causing the steel bar limiter to move horizontally or vertically, which in turn leads to the displacement deviation of the groove size of the foundation of the wind turbine tower wall. 2. Low work efficiency: The main problem is that each time a rebar limiter needs to be made, the welding and fixing of the limiter is extremely inconvenient, resulting in low construction efficiency. 3. High construction losses: During construction, the steel bar limit clips are welded to the steel bars of the pedestal. After construction, they remain in the concrete structure and cannot be reused, resulting in waste. Summary of the Invention
[0003] The purpose of this utility model is to address the deficiencies of the existing technology by providing a wind turbine tower wall foundation groove template installation and positioning device. The device provides a stable and secure support connection, preventing displacement due to construction loads during construction. It effectively ensures construction quality, and is safe, reliable, easy to operate, reusable, economical, and practical.
[0004] The technical solution adopted by this utility model to achieve the above-mentioned objectives is as follows: a wind turbine tower wall foundation groove template installation and positioning device, including a tower groove template, a balancing force rod, a balancing force rod fixing component, and a connecting flat steel. The tower groove template is formed by connecting multiple arc groove templates in sequence. Each arc groove template includes a groove bottom template, a groove side template, and a groove template reinforcing rib. The groove bottom template is a section of arc-shaped flat steel plate. The groove side templates are connected to the inner and outer circumferences of the groove bottom template, respectively. The groove template reinforcing ribs are connected to the groove bottom template and the groove side template, respectively. The two ends of the balancing force rod cross over the upper side of the tower groove template, and the two ends of the balancing force rod are connected to the top of the inner steel side mold and the top of the outer steel side mold of the foundation platform side wall, respectively, through the balancing force rod fixing component. The balancing force rod is connected to the groove template reinforcing rib through the connecting flat steel near the middle section.
[0005] A further technical solution of this utility model is: four groove template reinforcing ribs are connected to each arc groove template. The two groove template reinforcing ribs located in the middle section of the arc groove template are connected to demolding lifting ears on their sides. The groove template reinforcing ribs located at both ends of the arc groove template are provided with through bolt holes. The bolts pass through the bolt holes on the corresponding end groove template reinforcing ribs of the two adjacent arc groove templates, so that the two adjacent arc groove templates can be connected into an integral structure.
[0006] A further technical solution of this utility model is: the middle of both ends of the balancing force rod is provided with a U-shaped hole recessed inward, and the balancing force rod fixing component includes a bolt extending upward and a U-shaped steel clamp welded to the lower side of the bolt head. The bolt extending upward can be positioned in the U-shaped hole at both ends of the balancing force rod, and the balancing force rod is locked with a nut on the upper side of the U-shaped hole. The U-shaped opening of the U-shaped steel clamp faces inward and can be mutually clamped and positioned with the top of the inner mold of the platform column or the top of the outer mold of the platform column.
[0007] A further technical solution of this utility model is: the balancing force bar is connected to one end of the connecting flat steel by welding at the middle position, and the end of the connecting flat steel away from the balancing force bar is provided with a connecting hole, and the connecting flat steel is connected to the reinforcing rib of the groove template through the connecting hole.
[0008] A further technical solution of this utility model is: the lower side of both ends of the balancing force rod is provided with a force-bearing bracket that can support the top of the inner mold of the pedestal and the top of the outer mold of the pedestal.
[0009] The present invention provides a wind turbine tower wall foundation groove template installation and positioning device, which has the following advantages: Economical and practical: The tower groove formwork is supported on the top of the column side formwork by a balancing force rod, balancing force rod fixing parts, and connecting flat steel. The height of the U-shaped steel clamp groove can be adjusted by adjusting the height of the balancing force rod fixing parts. It is easy and quick to operate and has high installation efficiency through manual fixing and moving device. It does not require welding to the already tied steel bars, which not only saves labor and material costs, but also allows for reuse. It saves the time and labor and material costs of fixing the tower groove formwork fixing parts. It is easy to install and disassemble, shortening the construction period. It plays an important role in the installation of wind turbine tower wall foundation groove formwork, especially when there are high requirements for appearance size and elevation.
[0010] 2. Safe and reliable: The tower groove template is supported on the top of the pedestal side formwork by a balancing force bar, a balancing force bar fixing component and a connecting flat steel, which is firmly installed. The force bar is supported by channel steel, which avoids displacement and deformation and reduces safety risks.
[0011] 3. Quality Assurance: The new groove template installation and positioning device of this utility model ensures strength and rigidity. During operation, there is no tilting or misalignment of the groove geometry, which can avoid quality problems such as insufficient local load-bearing capacity and affecting the stability of the fan.
