Description

Technical Field

[0001] This utility model belongs to the field of wind power generation equipment, specifically an installation device suitable for quick installation of wind turbine anchor bolt nuts. Background Technology

[0002] During wind turbine construction, the nuts on the anchor bolts play a crucial role in securing the anchor plates and tower. When installing the anchor bolts, the nuts must be threaded through first. Due to process requirements, this process must avoid applying additional torque; otherwise, it will damage the anchor bolt and anchor plate fixing device, leading to anchor plate misalignment and affecting the overall stability and safety of the wind turbine structure.

[0003] Currently, most common nut-installing devices on the market are electrically or hydraulically driven, such as electric wrenches or hydraulic torque tools. These devices have the following shortcomings during construction: First, the issue of additional torque: Existing electrically or hydraulically driven devices often generate significant torque during installation, which directly conflicts with the process requirements for installing wind turbine anchor bolt nuts. This additional torque may cause damage to the anchor bolt threads, anchor plate displacement, or loosening of the fixing device, leading to construction quality defects. Second, safety risks: Torque fluctuations in electrically or hydraulic devices may result in excessive tightness or looseness, affecting installation accuracy and potentially causing long-term safety hazards, such as anchor bolt fatigue fracture. Utility Model Content

[0004] The present invention aims to provide an installation device suitable for the quick installation of anchor bolt nuts for wind turbines, in order to solve the problems of torque addition and insufficient safety when using existing electric wrenches or hydraulic torque tools.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An installation device for quickly inserting wind turbine anchor bolt nuts includes a rotating rod, a roller, and a conveying component. The roller is fixedly sleeved on the rotating rod, and the conveying component has a closed ring structure, with one end sleeved on the roller surface and the other end used to engage with the wind turbine anchor bolt nut. The roller surface is configured to engage with the concave and convex surfaces of the conveying component, and the inner surface of the conveying component is provided with a toothed structure adapted to the concave and convex surfaces.

[0006] As a limitation of this utility model, the conveyor is a belt.

[0007] As a further limitation of this utility model: the bottom of the rotating rod is provided with a pointed structure, and the tip of the pointed structure is set towards the ground.

[0008] As another limitation of this utility model: a handle is fixedly provided at the top of the rotating rod.

[0009] As a further limitation of this utility model: the rotating rod and the handle are made of steel.

[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows: This invention includes a mechanical transmission system consisting of a rotating rod, rollers, and a transmission component. The rollers are fixedly sleeved on the rotating rod, and the transmission component is a closed-loop structure, with one end sleeved on the roller surface and the other end used to engage with the wind turbine anchor bolt nut. During implementation, the torque is input through manual control of the rotating rod, transmitted via the engagement of the roller's concave and convex surfaces with the transmission component, ultimately achieving the rotational insertion of the nut. This invention completely avoids the instantaneous torque impact of power tools, achieving "torque-free" insertion; furthermore, the manual control of the rotating rod ensures smooth torque transmission, fundamentally eliminating the problem of anchor bolt thread damage and breakage caused by torque fluctuations, thus improving safety.

[0011] In summary, this invention enables rapid, torque-free installation of anchor bolts and nuts, with a simple structure and high safety; this invention is applicable to the wind power construction industry. Attached Figure Description

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and do not constitute a limitation thereof.

[0016] like Figures 1-2 As shown, this embodiment includes a rotating rod 1, a roller 2, and a transmission component 3, which together constitute a mechanical transmission system for quickly and without additional torque inserting the nut.

[0017] Roller 2 is fixedly mounted on rotating rod 1. Rotating rod 1 has a cubic structure and is made of steel. Roller 2 is made of alloy steel, and a square central hole 21 is opened in the center of roller 2. Roller 2 and rotating rod 1 are interference-fitted to ensure that they are firmly connected without loosening. The rolling surface of roller 2 is set as a concave-convex surface 22 for engaging the conveyor 3. In this embodiment, several protrusions are arranged at intervals along the circumference of roller 2 on the rolling surface, and the parts without protrusions form concave surfaces relative to the protrusions, forming a concave-convex surface 22. It should be noted that in this embodiment, the rolling surface of roller 2 (also known as the concave-convex surface 22) is located between the top surface 23 and the bottom surface 24, and the diameter of the rolling surface is smaller than the diameter of the top surface 23 and the bottom surface 24. After the conveyor 3 is mounted on the concave-convex surface 22, the top surface 23 and the bottom surface 24 of roller 2 can hold the conveyor 3 in place, preventing it from dislodging. In this embodiment, the conveyor 3 is a belt with a closed loop structure. The inner surface of the belt is molded with a toothed structure that matches the concave and convex surfaces 22 of the roller 2 to ensure transmission stability. The toothed structure is not shown in the figure. One end of the belt is fitted onto the rolling surface of the roller 2, and the other end is used to connect with the wind turbine anchor bolt nut.

[0018] like Figure 1 As shown, the bottom of the rotating rod 1 is configured with a pointed structure 4, with the tip of the pointed structure 4 facing the ground. In this embodiment, the pointed structure 4 is integrally formed with the rotating rod 1; in other words, the bottom of the rotating rod 1 is machined into a conical pointed structure 4, with the cone tip pointing downwards. In use, the rotating rod 1 uses the cone tip to penetrate the ground to form a stable fulcrum, allowing the device to remain stable when the operator applies rotational force to the rotating rod 1.

[0019] like Figure 1 As shown, a handle 5 is fixed to the top of the rotating rod 1 for easy hand rotation. The handle 5 is also made of steel. In this embodiment, the top of the rotating rod 1 is bent at 90 degrees to form an L-shape. The handle 5 is a straight rod, which is vertically fixed to the bent end 6 of the rotating rod 1 by welding.

[0020] In this embodiment, the rotating rod 1 is inserted into the central hole 21 and fixed to the roller 2. Then, one end of the conveying component 3 is fitted onto the concave-convex surface 22 of the roller 2, and the other end is fitted onto the wind turbine anchor nut. The handle 5 is rotated so that the pointed structure 4 penetrates the ground for fixing. After installation, the handle 5 is rotated, which drives the rotating rod 1 and roller 2 to rotate. The concave-convex surface 22 drives the conveying component 3 to rotate, and the conveying component 3 drives the wind turbine anchor nut at the other end to rotate, thus completing the quick installation of the wind turbine anchor nut.

[0021] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
