Description

Technical Field

[0001] This utility model relates to a safety protection device for wind turbine construction, and in particular to a safety protection device for the construction of wind turbine foundation anchor cages. Background Technology

[0002] The wind turbine foundation anchor cage is a key component in the wind turbine foundation structure. Its height is greater than 4 meters, and it mainly consists of a lower anchor plate 8, anchor bolts 7, an upper anchor plate 1, and a bottom anchor support 9 (e.g., ...). Figure 1 (As shown). Adjustments and acceptance of the upper anchor plate 1 and anchor bolts 7, as well as the binding of the wind turbine foundation reinforcement, all require work in the area of ​​the upper anchor plate 1, which constitutes high-altitude work. During construction, a truck crane hook is often used to suspend workers with safety belts for protection. However, the swaying of the hook can cause workers to lose their balance and fall into the anchor bolt cage. Furthermore, when the truck crane is not on site, there are no safety protection devices available for work on the upper anchor plate 1, thus increasing the risk of falls and accidents. Therefore, there is a problem of insufficient safety protection devices during the installation and acceptance of anchor bolts and anchor plates on the wind turbine foundation.

[0003] Meanwhile, if a truck crane is used for worker safety protection during construction, the construction cost will be high. For example, using a 25-ton truck crane costs 2,000 yuan per shift. The adjustment, acceptance, and rebar binding of anchor bolt 7 require four shifts, which would bring the machinery cost to 8,000 yuan. Moreover, it can only be used for hoisting workers' safety belts, resulting in low efficiency. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model provides a safety protection device that ensures the safety of personnel during the installation and inspection of wind turbine foundation anchor cages, improves the efficiency of installation and inspection, enhances the protective effect of construction, and reduces construction costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution. A safety protection device for the construction of wind turbine foundation anchor cages includes an annular upper anchor plate equipped with anchor bolts. Z-shaped clamps are fitted on both the inner and outer sides of the upper anchor plate. The lower ends of the clamps are fixedly connected to a long strip-shaped base plate on the bottom surface of the upper anchor plate by bolts. The upper ends of the clamps are pressed against the upper surface of the inner and outer sides of the upper anchor plate by screws. A support rod is vertically installed on the upper surface of the inner end of the base plate. A through hole is provided at the top of the support rod, and a safety rope is threaded through the through hole of an adjacent support rod. A bolt is provided in the middle section of the support rod, and one end of the diagonal brace is connected to the bolt, while the other end is connected to the lower end of the clamp.

[0006] Furthermore, the diagonal brace is a steel pipe, round steel bar, or steel cable.

[0007] Furthermore, the support rod is a square steel tube or a round tube.

[0008] Furthermore, the through holes at the top of the support rod are all at the same height.

[0009] Furthermore, at least six long strip-shaped bottom plates are evenly distributed below the upper anchor plate.

[0010] Furthermore, the safety rope is sequentially connected to the through holes of adjacent support rods.

[0011] This utility model uses clamps and is connected by a square tube bracket and safety rope. During the installation and acceptance of the fan, the inspectors can directly hang the hooks on their safety belts onto the safety rope, forming a safety protection device that protects construction workers and prevents falls from heights. It is also easy to disassemble and install, the bolted connection facilitates transportation, and it can be reused multiple times, greatly reducing construction costs. It can be used as a safety protection device during the installation of steel roof trusses, purlins, and roof panels in steel structure factory construction. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments. See also Figures 2 to 4 A safety protection device for the construction of wind turbine foundation anchor cages includes an annular upper anchor plate 1 equipped with anchor bolts 7, and at least six elongated base plates 3 evenly distributed below the upper anchor plate 1. Z-shaped clamps 2 are fastened to both the inner and outer sides of the upper anchor plate 1. The lower end of the clamps 2 is fixedly connected to the elongated base plates 3 on the bottom surface of the upper anchor plate 1 by bolts, and the upper end of the clamps 2 is pressed against the upper surface of the inner and outer sides of the upper anchor plate 1 by screws. A support rod 4 with a square steel pipe or a round pipe structure is vertically installed on the upper surface of the inner end of the base plate 3. The top of the support rod 4 has a through hole, and the through holes of adjacent support rods 4 are at the same height, with safety ropes 5 sequentially connected in series in the holes. A bolt 10 is installed in the middle section of the support rod 4. One end of a diagonal brace 6 is connected to the bolt 10, and the other end is connected to the lower end of the clamp 2. The diagonal brace 6 can be a steel pipe, round steel, or steel cable.

[0018] Example:

[0019] This utility model device uses a "Z"-shaped clamp 2 and screws to fix the base plate 3 and anchor plate 1 together, connecting the base plate 3 to the lower end of the support rod 4. To enhance the stability of the support rod 4, the upper end of the support rod 4 is connected to the diagonal brace 6 for reinforcement. This forms a wind turbine anchor plate safety protection device on the wind turbine foundation anchor cage. During construction, six adjacent devices are connected together by safety ropes 5 passing through the through hole at the top of the support rod 4, forming a ring-shaped safety protection.

[0020] When installing the upper anchor plate 1 of the wind turbine foundation, firstly, install six sets of support rods 4 evenly distributed on the upper anchor plate 1 (e.g., Figure 2 As shown), the safety rope 5 is then connected in a ring along the upper end of the support rod 4 on the inner circumference of the upper anchor plate 1. When adjusting and inspecting the flatness of the upper anchor plate 1 and the exposed length of the anchor bolt 7, the construction workers hang the hook of the safety belt on the safety rope 5, which can play a safety protection role for the construction workers and prevent them from falling from height.

[0021] When assembling this utility model as a whole, the six sets of this device on the upper anchor plate 1 are first assembled on the ground. Then, the assembled upper anchor plate 1 is connected to the anchor bolt 7 by a truck crane. This way, the construction workers can assemble it on the ground, which avoids the risks of working at height.

[0022] This device uses φ16 bolts 10 to connect the support rod 4 and the diagonal brace 6, which facilitates disassembly and installation. The bolt connection is easy to transport and can be reused.

[0023] This device can also be used as a safety protection device during the construction of various types of steel structure workshops. By changing the size of the "Z"-shaped clamp 2, the clamp 2 can be clamped onto steel structures of different specifications, enabling serial and panel assembly installation. It can also play a safety protection role when construction workers are installing steel roof trusses, purlins, and roof panels.
