Description

Technical Field

[0001] The invention belongs to the field of mechanical structures, and in particular relates to a multifunctional lightweight turntable. Background Art

[0002] The radar's azimuth turntable provides mounting support and azimuth rotation for the radar antenna. As the array size of radar antennas increases, the array weight increases, requiring the turntable to carry a larger load. The increased antenna functionality leads to an increasing number of array devices, and the limited array space is no longer sufficient to accommodate these new devices. Radar operates in harsh environments, requiring equipment with excellent environmental adaptability, necessitating a sealed turntable design. Current radar turntable structures can achieve continuous rotation of the antenna array and meet high-precision servo control requirements. However, these turntable structures do not meet the new demands for large-scale, multifunctional, and lightweight antenna arrays, nor can they accommodate the highly integrated installation requirements for newly added equipment. Therefore, a new multifunctional, lightweight, and environmentally adaptable turntable is urgently needed to meet the new demands for large-scale, high-performance antennas. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, the present invention proposes a multifunctional, highly integrated, and environmentally adaptable radar turntable to solve the new requirements of large-scale and heavy radar antennas, large equipment volume, and harsh working environment. It can support large-scale array turntables and provide equipment installation space, while realizing dynamic interconnection of water and electricity in the rotating state.

[0004] The multifunctional lightweight turntable of the present invention includes a turntable frame, an azimuth drive motor, a platform, an azimuth bearing, an array lug interface and a cylinder lug interface; the turntable frame transfers the array weight to the bottom mounting surface through its own force transmission frame, and relevant electronic equipment is installed inside the turntable frame. At the same time, it is connected to the antenna array through the array lug interface, connected to the inverted cylinder through the cylinder lug interface, and connected to the platform through the azimuth bearing through the azimuth bearing interface. The drive motor in the platform drives the azimuth bearing to realize 360° continuous rotation of the turntable. The turntable frame is connected to the merge ring and the water hinge through the transition plate to realize dynamic transmission of power supply, control signals and coolant when the turntable rotates continuously.

[0005] Furthermore, the azimuth bearing adopts a labyrinth seal structure to achieve dynamic sealing.

[0006] Furthermore, a platform sealing plate and a platform sealed outlet are used at the bottom of the platform to seal the platform as a whole, and cables and water pipes enter and exit through the platform sealed outlet to achieve isolation from the external environment.

[0007] Furthermore, a gear cover is provided on the outside of the azimuth bearing.

[0008] The beneficial effects of the present invention are

[0009] (1) Multifunctional and highly integrated design: The internal and external interfaces of the turntable are integrated, and information processing equipment and other equipment are installed in the internal space; the external design structure installation interface of the turntable, including the array support ear interface, cylinder interface, bearing installation interface, etc., realizes the highly integrated design and installation of electronic equipment, hydraulic equipment, etc., and effectively reduces the size and weight of the turntable.

[0010] (2) Lightweight design of turntable: The turntable frame structure transmits the array weight load and the cylinder load to the bottom bearing mounting surface through the turntable skeleton with the minimum transmission path. The force transmission path is reasonable, and the weight of the turntable skeleton is reasonably allocated to the area with high stress, so as to realize the lightweight design of the turntable.

[0011] (3) Dynamic interconnection design of water and electricity rotation: The power and cooling water on the platform are transferred to the antenna array through water hinges and confluence rings, realizing dynamic transmission when the turntable is rotating.

[0012] (4) Sealing design, strong environmental adaptability. The turntable azimuth bearing adopts a labyrinth seal design, and the lower part of the turntable and the platform are integrated with the seal to achieve a fully sealed design of the turntable, effectively isolating it from the harsh external environment.
