Description

Technical Field

[0001] The invention relates to a turntable, in particular to a rotary hydraulic turntable, belonging to the technical field of wind power generation equipment. Background Art

[0002] The fan hub is one of the key components of a wind turbine generator set. It plays an important role in supporting the fan blades and transmitting torque. It connects the root of the blades and the main shaft of the fan, and is responsible for transmitting the force generated by the blades to the main shaft, thereby driving the generator to generate electricity. The design and manufacture of the fan hub is a complex process involving many aspects of knowledge such as material science, mechanical analysis, manufacturing technology and optimization design. When assembling the fan hub, a turntable is usually required to receive and fix the fan hub to facilitate free angle changes during assembly.

[0003] The turntable can maintain the balance of the hub during the assembly process, which is crucial for subsequent dynamic testing and long-term operation. Secondly, the rotating base allows the hub to be quickly positioned at multiple angles, and the assembler can easily move around the turntable to different positions of the hub, which makes it more convenient to assemble and adjust, thereby speeding up the assembly speed and improving overall efficiency. However, the turntable in the prior art is usually a mechanical turntable or an electric turntable, both of which have poor high load-bearing capacity and stability, and the transmission of force is not uniform enough, and they cannot overcome large inertial deflection well, which makes the rotation angle of the fan hub not accurately controlled. At the same time, both of them have high energy consumption during operation, and their internal energy conversion efficiency is low, which has a low improvement in production efficiency.

[0004] Therefore, there is an urgent need to improve the rotary hydraulic turntable to solve the above-mentioned problems. Summary of the invention

In this process, the hydraulic drive mechanism used drives the wheel hub body more stably. The hydraulic drive mechanism has high load-bearing capacity and stability when driving the wheel hub body, provides uniform, precise and controllable force, and has less loss during energy transfer, so that the rotary hydraulic turntable has lower energy consumption when in use, which significantly improves production efficiency.

DETAILED DESCRIPTION

[0028] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0029] like Figure 1-Figure 8As shown, the rotary hydraulic turntable provided in this embodiment includes a hub body 1, on which a mounting portion 2 and a cavity 3 located inside the hub are provided; a mounting and fixing mechanism 4, which is composed of a positioning plate 401 and a hydraulic rotating disk 402, one end of which corresponds to the mounting portion 2 of the hub body 1 and can be bolted; a base mechanism 5, on which the hub body 1 is connected through the mounting and fixing mechanism 4, and the base mechanism 5 is used to receive and fix the hub body 1, and a rotating member 6 is provided on the base mechanism 5, and the rotating member 6 is connected to the mounting and fixing mechanism 4; a hydraulic drive mechanism 7, which is connected to the base mechanism 5, and the hydraulic drive mechanism 7 provides power input for the rotation of the rotating member 6 The hydraulic drive mechanism 7 drives the rotating part 6 and the installation and fixing mechanism 4 to rotate, thereby driving the hub body 1 to rotate. When in use, the installation and fixing mechanism 4 is first installed on the base mechanism 5. During the connection process, the installation and fixing mechanism 4 is connected to the base mechanism 5 with bolts, and then the hub body 1 is connected to the end of the installation and fixing mechanism 4 away from the base mechanism 5. Finally, when the hub body 1 is assembled, the hydraulic drive mechanism 7 is used. Through the operation of the hydraulic drive mechanism 7, the installation and fixing mechanism 4 on the base mechanism 5 is driven to rotate, and then the hub body 1 connected to the installation and fixing mechanism 4 is driven to rotate, so as to facilitate the hub body 1 to rotate freely during assembly.

[0030] When the above structure is in use, compared with the prior art structure that uses a mechanical turntable or an electric turntable, the hydraulic drive mechanism 7 used in the technical solution of the present invention drives the hub body 1 more stably. The hydraulic drive mechanism 7 has a higher load-bearing capacity and stability when driving the hub body 1, and provides uniform and controllable force. The driving method in the hydraulic drive mechanism 7 has a higher efficiency in energy conversion efficiency and less loss during energy transfer, which means that the hub body 1 is more efficient and energy-saving during rotation. The hydraulic drive method in the hydraulic drive mechanism 7 can achieve fine speed and position control, which is particularly important for the hub body 1 in the assembly that requires high-precision positioning. Therefore, in the technical solution of the invention, the hydraulic drive mechanism 7 used can maintain precise rotational motion under various load conditions.

[0031] Among them, Figure 2 as well as Figure 4 As shown, the positioning plate 401 is provided with a plurality of positioning mounting holes 4011 corresponding to the mounting portion 2 of the hub body 1 , and the hub body 1 is connected to the positioning mounting holes 4011 by bolts, thereby mounting the hub body 1 on the positioning plate 401 .

[0032] Further, such as Figure 4 as well as Figure 5As shown, the hydraulic rotating disk 402 is composed of a connecting plate 4021 and a clamping plate 4022. The connecting plate 4021 is connected to the clamping plate 4022 through a supporting plate 4023. The connecting plate 4021 is provided with a plurality of positioning and mounting holes 4024 corresponding to the positioning and mounting holes 4011 on the positioning plate 401. A circular slot 1 4025 is provided inside the connecting plate 4021. A circular slot 2 4026 is provided on the clamping plate 4022. The circular slot 1 4025 is connected to the circular slot 2 4026, and the center line of the circular slot 1 4025 is collinear with the center line of the circular slot 2 4026.

[0033] Furthermore, Figure 4 as well as Figure 5 As shown, there are a plurality of support plates 4023, and the plurality of support plates 4023 are equidistantly arranged around the central axis of the clamping plate 4022, and one end of the plurality of support plates 4023 close to the central axis of the clamping plate 4022 corresponds to the side of the circular slot 2 4026. When the hub body 1 is connected to the hydraulic rotating disk 402, the plurality of support plates 4023 can well and evenly transfer the weight transmitted by the hub body 1 from the connecting plate 4021 to the clamping plate 4022.

[0034] Going further, Figure 6 as well as Figure 7 As shown, the base mechanism 5 includes a base platform 501, and the rotating member 6 includes a clamping disk 601, which is connected to the base platform 501. The clamping disk 601 is provided with a slot 602 corresponding to the clamping plate 4022. The clamping plate 4022 is installed on the clamping disk 601 through the slot 602. The slot 602 can limit the clamping plate 4022 when it is installed, so that the clamping plate 4022 is more stable and convenient to install.

[0035] Further, such as Figure 7 as well as Figure 8 As shown, the base platform 501 is provided with an inclined portion 8, and the clamping plate 601 is connected to the inclined portion 8. The inclined portion 8 is a table surface that is inclined from one side of the base platform 501 to the other side. When the hub body 1 is installed on the mounting and fixing mechanism 4, because the mounting and fixing mechanism 4 is installed on the base mechanism 5,

[0036] The hydraulic drive mechanism 7 includes a bearing 15 connected to the clamping plate 601 and a motor 9 connected to the base platform 501. One end of the bearing 15 extends into the circular slot 1 4025 and the circular slot 2 4026. The output end of the motor 9 is connected to the oil pump 10. The output end of the oil pump 10 is connected to the oil pipe 11. The output end of the oil pipe 11 extends to the inside of the base platform 501.

[0037] The hydraulic drive mechanism 7 also includes a hydraulic motor 12, which is connected to the output end of the oil pipe 11. The hydraulic motor 12 is connected to the oil outlet pipe 11. The output end of the hydraulic motor 12 is connected to a gear assembly. The gear assembly includes a turbine ring 13 and a worm 14. The worm 14 is connected to the output end of the hydraulic motor 12. The worm 14 is screwed together with the turbine ring 13. The turbine ring 13 is connected to a bearing 15. The hydraulic motor 12 is a prior art device, which is mainly driven by hydraulic oil and will not be elaborated in detail. The combination of the motor 9, the oil pump 10 and the oil pipe 11 provides power input for the operation of the hydraulic motor 12.

[0038] When the above structure is in use, a base mechanism 5 is provided under the wheel hub body 1 to support and install the wheel hub body 1, and then an installation and fixing mechanism 4 is provided between the wheel hub body 1 and the base mechanism 5. Under the action of the positioning plate 401, the connecting plate 4021 and the clamping plate 4022, the wheel hub body 1 is positioned and installed, and then the installation and fixing mechanism 4 is driven to rotate by the hydraulic drive mechanism 7, which will drive the wheel hub body 1 to rotate. When the hydraulic drive mechanism 7 is in use, the hydraulic rotating disk 402 is driven to rotate by the mutual cooperation of the motor 9, the oil pipe 11, the hydraulic motor 12, the turbine ring 13 and the worm 14, thereby driving the wheel hub body 1 to rotate. In this process, the hydraulic drive mechanism 7 used drives the wheel hub body 1 more stably. When the hydraulic drive mechanism 7 drives the wheel hub body 1, it has a higher load-bearing capacity and stability, provides uniform, precise and controllable force, and has less loss during energy transfer, so that the rotary hydraulic turntable has lower energy consumption when in use, which significantly improves production efficiency.
