[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0040] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0041] The wind turbine generator anchor cage structure includes an upper anchor plate 22, a lower anchor plate, and an anchor bolt assembly connecting the upper anchor plate 22 and the lower anchor plate. The specific structure can be found in patent document CN119640809A, entitled "Auxiliary Device for Anchor Bolt Installation of Wind Turbine Generator Foundation and Anchor Bolt Assembly." This utility model's wind turbine generator anchor bolt installation safety auxiliary device is installed on the upper anchor plate 22 to provide safety assurance for construction workers on the upper anchor plate 22.
[0042] Reference Figure 1 This utility model provides a safety auxiliary device for the installation of anchor bolts in wind turbine generator sets, including a support frame, a pulley block 4, a guide wheel block 5, and a support rod assembly.
[0043] The support frame is the basic framework of the entire device, consisting of a top plate 1 and two opposing side plates 2. The two ends of the top plate 1 are connected to the two side plates 2 by welding or other fixing methods to form a stable frame structure. The side plates 2 and the top plate 1 together support the overall structure of the device.
[0044] The pulley block 4 is installed on the lower surface of the top plate 1, while the guide wheel block 5 is installed on the opposite surfaces of the two side plates 2. The rotation shaft of the pulley block 4 is set in the horizontal direction and is used to support the upper surface of the upper anchor plate 22. The rotation shaft of the guide wheel block 5 is set in the vertical direction, and its rim is used to abut against the lower edge of the upper anchor plate 22, serving as a guide and limiting function.
[0045] Preferably, a middle plate 6 and a bottom plate 7 are fixedly connected to the opposite surfaces of both side plates 2. A guide wheel bracket 8 is connected between the middle plate 6 and the bottom plate 7, and a guide wheel assembly 5 is rotatably connected to the guide wheel bracket 8. Specifically, the guide wheel bracket 8 has an obtuse-angled triangular structure, with a guide wheel assembly 5 installed at each end of its longest side, and a connecting block 9 hinged at its obtuse angle. The middle plate 6 and the bottom plate 7 are arranged horizontally, and the guide wheel bracket 8 is slidably connected between the middle plate 6 and the bottom plate 7. A first screw 10 is threadedly connected to the side plate 2 located between the middle plate 6 and the bottom plate 7. One end of the first screw 10 is rotatably connected to the connecting block 9, and the other end is fixedly connected to a first knob 11. By rotating the first knob 11, the position of the guide wheel bracket 8 between the middle plate 6 and the bottom plate 7 can be adjusted, thereby adjusting the rotatable connection between the guide wheel assembly 5 and the side wall of the upper anchor plate 22.
[0046] Combined with reference Figure 2 The guide wheel set 5 has two structural options available:
[0047] Structure 1: The guide wheel group 5 consists of multiple single-sided wheels. Each single-sided wheel has a rim on its lower edge. The rim is in close contact with the lower edge of the upper anchor plate 22 to prevent overturning.
[0048] Structure 2: The guide wheel assembly 5 consists of multiple double-sided wheels. The lower edge of the double-sided wheels directly contacts the lower edge of the upper anchor plate 22, which also serves to prevent overturning.
[0049] Combined with reference Figure 3 A pulley bracket 12 is provided between the two side plates 2, and a pulley assembly 4 is installed on the lower surface of the pulley bracket 12. Two connecting seats 13 are fixedly connected to the upper surface of the pulley bracket 12. Two second screws 14 are threaded vertically onto the top plate 1. The lower ends of the second screws 14 are hinged to the connecting seats 13 one by one, and the upper ends are fixedly connected to the second knobs 15. By rotating the second knobs 15, the position of the pulley bracket 12 on the top plate 1 can be adjusted, thereby adjusting the height of the pulley assembly 4. By adjusting the height of the pulley assembly 4, this utility model can adjust the relative height between the guide wheel assembly 5 and the upper anchor plate 22, so that the guide wheel assembly 5 is opposite to the side wall of the upper anchor plate 22, and the wheel edge of the guide wheel assembly abuts against the lower edge of the upper anchor plate 22, thereby achieving the effect of preventing overturning. At the same time, the above-mentioned hinge device can realize the individual adjustment of the two second screws 14, avoiding the adjustment process where the two second screws 14 cannot rotate synchronously.
[0050] In a preferred embodiment of this invention, the guide wheel assembly 5 includes a plurality of rotating wheels arranged in a rectangular array on the lower surface of the pulley bracket 12. The positions of the rotating wheels are preferably offset from the anchor bolt holes of the upper anchor plate 22.
[0051] Refer again Figure 1 The support rod assembly is fixedly connected to the upper surface of the top plate 1 and is used to install the hanging ring 3. The hanging ring 3 is used to hang safety belts or other safety devices to ensure the safety of workers. The support rod assembly is a telescopic structure. Specifically, it includes a fixed sleeve 16, a sliding rod 17, and fasteners 19. The fixed sleeve 16 is arranged vertically, and its lower end is fixedly connected to the upper surface of the top plate 1. The lower end of the sliding rod 17 is slidably inserted into the fixed sleeve 16, and its height can be adjusted as needed. The fixed sleeve 16 is provided with a first connecting hole, and the sliding rod 17 is provided with multiple second connecting holes 18. By inserting the fasteners 19 into the first connecting holes and the second connecting holes 18, the fasteners 19 are preferably bolts and screws, and the sliding rod 17 can be fixed at the required height position. The upper end of the sliding rod 17 is fixedly connected to a connecting plate 20, and a hanging ring 3 is installed on the connecting plate 20 for hanging safety devices.
[0052] In addition, to improve the overall stability and strength of the device, reinforcing ribs 21 are fixedly connected between the top plate 1 and the side plate 2, and between the top plate 1 and the fixed sleeve 16. These reinforcing ribs 21 can be connected by welding or other fixing methods to ensure the robustness and reliability of the device during use.
[0053] The steps for using this utility model are as follows:
[0054] Step 1: Adjust the device position: According to the actual construction requirements, place the wind turbine generator anchor bolt installation safety auxiliary device above the upper anchor plate 22, so that the rotating wheel abuts against the surface of the upper anchor plate 22. Adjust the height of the pulley bracket 12 by rotating the second knob 15, so that the guide wheel assembly 5 is opposite to the side wall of the upper anchor plate 22, and the lower edge of the guide wheel assembly 5 abuts against the lower edge of the upper anchor plate 22. Adjust the position of the guide wheel bracket 8 by rotating the first knob 11, so that the wheel surface of the guide wheel assembly 5 contacts the side wall of the upper anchor plate 22.
[0055] Step 2: Adjust the height of the support rod assembly: Adjust the height of the sliding rod 17 as needed. After adjustment, insert the fastener 19 between the first connecting hole and the second connecting hole 18 to fix the height of the support rod assembly.
[0056] Step 3: Safety device installation: Hang the safety belts or other safety devices of the construction workers on the hanging ring 3 to ensure the safety of the workers during the construction process.
[0057] Step 4, Construction Operation: During the installation of anchor bolts, workers can use pulley block 4 and guide wheel block 5 to guide the movement of safety ropes or other auxiliary tools to ensure the smooth progress of the construction process.
[0058] Step 5: Disassembly: After the construction work is completed, adjust the position of the guide wheel bracket 8 by rotating the first knob 11 so that the wheel surface of the guide wheel group 5 is not in contact with the side wall of the upper anchor plate 22, and then remove the device of this utility model from the upper anchor plate 22.
[0059] Existing devices require specific installation based on the top structure of the anchor cage, resulting in poor versatility and difficulty in adapting to anchor cages of different specifications and shapes. This invention, by employing an adjustable guide wheel bracket 8 and pulley bracket 12, can flexibly adapt to upper anchor plates 22 of different specifications. Specifically, by rotating the first knob 11 to adjust the position of the guide wheel bracket 8, the guide wheel assembly 5 can be tightly fitted against the side wall of the upper anchor plate 22, with its wheel rim abutting against the lower edge of the upper anchor plate 22. This tight contact design between the wheel rim of the guide wheel assembly 5 and the lower edge of the upper anchor plate 22 not only provides guidance but also effectively prevents the device from overturning during construction, further enhancing its stability. This ensures that the device can be stably installed and function effectively on anchor cages of different specifications.
[0060] In existing technologies, workers need to change hooks at different locations when installing nuts, which not only increases the complexity of the operation but also reduces work efficiency and causes inconvenience to actual construction. This invention effectively solves this problem by optimizing the hook design and the telescopic structure of the support rod assembly. Specifically, the support rod assembly adopts a telescopic design. By adjusting the height of the sliding rod 17 and fixing it with fasteners 19, the height of the hanging ring 3 can be quickly adjusted to meet the needs of different construction heights. Simultaneously, the pulley group 4 and guide wheel group 5 can be repositioned as the worker's position changes, making the movement of safety ropes or other auxiliary tools smoother. Workers do not need to frequently change hook positions during construction, thus greatly simplifying the operation process, improving work efficiency, and making the construction process more convenient and efficient.
[0061] In summary, this utility model, through innovative structural design and optimization, effectively solves the problems of poor versatility, inconvenient operation, and insufficient stability in existing technologies. It significantly improves the performance and practicality of the safety auxiliary device for wind turbine generator installation, providing strong support for the efficient and safe construction of wind turbine generators. It has broad application prospects and important practical significance.
