Description

Technical Field

[0001] This invention relates to a turntable, and more specifically to a large, heavy-duty tracking turntable with a radar lifting platform. Background Technology

[0002] Turntables, as high-precision azimuth rotation platforms, are widely used in fields such as photoelectric tracking and target recognition. Traditional photoelectric turntables typically carry optical payloads, such as visible light cameras and infrared thermal imagers, to detect, identify, and track targets. However, with the ever-increasing demands for target detection capabilities in modern warfare, single photoelectric detection methods are no longer sufficient to meet the needs of complex battlefield environments. Radar detection has advantages such as long operating range, strong anti-jamming capabilities, and all-weather operation. Integrating radar and photoelectric systems onto the same turntable to achieve multi-sensor information fusion has become an important development direction for improving target detection capabilities.

[0003] However, the introduction of the radar elevator platform presents significant challenges to the turntable. First, the elevator platform itself and the radar antenna it carries are enormous, significantly increasing the load on the turntable and placing higher demands on its load-bearing capacity, structural strength, and rigidity. Second, the lifting and lowering motion of the platform causes dynamic changes in its center of gravity, affecting its stability and motion accuracy. Furthermore, the vibrations and impacts generated by the radar system during operation further exacerbate the load on the turntable and may trigger structural resonance, impacting radar detection performance.

[0004] To address the aforementioned issues, there is an urgent need for a radar lifting platform that can be used in conjunction with an optoelectronic turntable. This lifting platform must possess the following characteristics: First, it must be able to support large-sized, heavy radar antennas with sufficient structural strength and stability; second, it must provide a sufficiently large platform to enable the elevation movement of the radar antenna and coordinate with the azimuth rotation of the optoelectronic turntable for omnidirectional detection; finally, it must minimize its own weight by employing lightweight materials and optimized structural design to reduce the load on the optoelectronic turntable and avoid excessively impacting its performance.

[0005] In conclusion, developing a radar lifting platform for use on an optoelectronic turntable is of great significance for improving target detection capabilities and realizing multi-sensor information fusion. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, the present invention provides a large heavy-duty tracking turntable with a radar lifting platform. Its advantages are that the radar lifting platform is installed on the photoelectric turntable to improve the target detection capability and realize the fusion of multi-sensor information. The radar lifting platform is fixed to the turntable box by the connecting frame, thereby improving the overall structural stability and load-bearing capacity of the system.

[0014] The orientation drive mechanism includes an orientation motor, an orientation motor stator, an orientation motor rotor, an angular contact ball bearing assembly, a conductive slip ring, a photoelectric encoder, and an orientation shaft.

[0015] The angular contact ball bearing assembly consists of two opposing angular contact ball bearings installed between the turntable housing and the azimuth axis.

[0017] It also includes a pitch limiting device, which includes four baffles. The four baffles are divided into two groups and placed symmetrically on both sides of the turntable housing.

[0020] The beneficial effects of the large, heavy-duty tracking turntable with radar lifting platform of the present invention are:

[0021] 1. A connecting frame is used to rigidly connect the radar lifting platform and the turntable housing, which can firmly fix the radar lifting platform and the turntable housing together to form an integral frame. This design can effectively distribute the concentrated force of the radar lifting platform and its load on the turntable, improve the overall structural stability and load-bearing capacity of the system, reduce vibration and deformation, ensure the accuracy and reliability of the radar during operation, and also simplify the installation and maintenance process, enhance system integration and environmental adaptability.

[0022] 2. The azimuth (pitch) drive uses a torque motor, allowing the optical path, azimuth axis (pitch axis), azimuth motor (pitch motor), and housing base to be arranged concentrically, resulting in a more compact structure. The bearing assembly uses two opposing angular contact ball bearings. This bearing combination ensures the stability of the shaft system while reducing the space occupied. It also houses the optical path to meet detection requirements. Both the azimuth and pitch rotation mechanisms can achieve 360-degree continuous rotation, and the pitch rotation mechanism can rotate within a range of -85° to 90°, facilitating detection needs.

[0023] 3. The added pitch and azimuth locking devices ensure the tightening requirements of the turntable during non-working states such as transportation, increasing safety and reducing the risk of damage. Attached Figure Description

[0042] like Figure 1-7 As shown, this embodiment describes a large, heavy-duty tracking turntable with a radar lifting platform. It combines a compact structural design with high-precision motion capabilities, making it suitable for integrated detection and reconnaissance scenarios. The turntable includes a turntable housing 1, a base 2, an azimuth drive mechanism 3, a pitch drive mechanism 4, a load 5, a radar lifting platform 6, a pitch limit device 7, a pitch locking device 8, and an azimuth locking device 9.

[0043] A large heavy-duty tracking turntable with a radar lifting platform includes a turntable housing 1, a base 2, an azimuth drive mechanism 3, a pitch drive mechanism 4, and a load 5. The load 5 is mounted on the turntable housing 1, and the pitch drive mechanism 4 is mounted on the other side of the turntable housing 1. The pitch drive mechanism 4 is used to drive the load 5 to perform pitch movement. The main body of the azimuth drive mechanism 3 is mounted inside the base 2. The turntable housing 1 is mounted on the base 2, and the azimuth drive mechanism 4 is used to drive the turntable housing 1 and the load 5 to rotate around the vertical direction.

[0044] The radar lifting platform 6 includes a connecting frame 6.6, which connects the radar lifting platform 6 to the turntable housing 1 and rotates together with the turntable housing 1.

[0045] A connecting frame 6.6 rigidly connects the radar lifting platform 6 to the turntable housing 1, firmly fixing the radar lifting platform 6 and the turntable housing 1 together to form an integral frame. This design effectively disperses the concentrated force of the radar lifting platform 6 and its load on the turntable, improving the overall structural stability and load-bearing capacity of the system, reducing vibration and deformation, ensuring the accuracy and reliability of the radar during operation, simplifying installation and maintenance procedures, and enhancing system integration and environmental adaptability.

[0046] The load 5 includes load 1 5.1 and load 2 5.2, which are respectively installed between the U-shaped structures on the turntable housing 1 and on one side thereof.

[0047] The radar lifting platform 6 also includes a driver 6.1, a worm gear 6.2, a worm 6.3, a lead screw 6.4, and a radar platform 6.5. The driver 6.1 is connected to the worm 6.3, the worm 6.3 is connected to the worm gear 6.2, the worm gear 6.2 is mounted on the lead screw 6.4, and the lead screw 6.4 is connected to the radar platform 6.5 via a threaded drive.

[0048] The lifting process of the radar platform 6 is driven by driver 6.1. Driver 6.1 is connected to worm gear 6.3, which is connected to worm wheel 6.2. Worm wheel 6.2 is mounted on a vertical shaft and connected to lead screw 6.4. Lead screw 6.4 is connected to radar platform 6.5. Driver 6.1 drives worm gear 6.3, which in turn drives lead screw 6.4 through worm gear 6.3 and worm wheel 6.2, causing radar platform 6.5 to lift and lower.

[0049] The pitch drive mechanism 4 includes a pitch motor 4.1, a pitch motor stator 4.1.1, a pitch motor rotor 4.1.2, a bearing assembly 4.2, a cylindrical roller bearing 4.2.1, a deep groove ball bearing 4.2.2, a photoelectric encoder 4.3, a pitch shaft 4.4, and a pitch shaft 4.5. The pitch motor 4.1 is a torque motor. The pitch motor stator 4.1.1 is connected to the turntable housing 1, and the pitch motor rotor 4.1.2 is connected to the pitch shaft 4.4. The other end of the pitch shaft 4.4 is connected to a load 5.1. The pitch shaft 4.5 is rigidly connected to both loads 5.1 and 5.2, so that the pitch motor 4.1 can simultaneously drive both loads 5.1 and 5.2. The pitch shafts 4.4 and 4.5 are connected to the turntable housing 1 through the bearing assembly 4.2. The photoelectric encoder 4.3 measures the rotation angle and speed of the pitch shaft.

[0050] The pitch rotation process is driven by the pitch motor 4.1. The pitch motor stator 4.1.1 is fixedly connected to the turntable housing 1, so that the pitch motor stator 4.1.1 follows the turntable housing 1 and remains stationary in the pitch direction. The pitch motor rotor 4.1.2 is fixedly connected to the pitch shaft 4.4, the pitch shaft 4.4 is fixedly connected to the load 5.1, and the load 5.1 is fixedly connected to the load 5.2. During the azimuth rotation process, the pitch motor 4.1 drives both the load 5.1 and the load 5.2 simultaneously.

[0051] Each bearing assembly 4.2 comprises a cylindrical roller bearing 4.2.1 and two opposing deep groove ball bearings 4.2.2. The cylindrical roller bearings 4.2.1 can withstand larger radial forces, improving the load-bearing capacity of the shaft system, while the two opposing deep groove ball bearings 4.2.2 can withstand axial forces in two directions, improving the stability of the shaft system.

[0052] The orientation drive mechanism 3 includes an orientation motor 3.1, an orientation motor stator 3.1.1, an orientation motor rotor 3.1.2, an angular contact ball bearing assembly 3.2, a conductive slip ring 3.3, a photoelectric encoder 3.4, and an orientation shaft 3.5. The orientation motor 3.1 is a torque motor. The orientation motor stator 3.1.1 is connected to the base 2, and the orientation motor rotor 3.1.2 is connected to the orientation shaft 3.5. The orientation shaft 3.5 is fixedly connected to the turntable housing 1. The conductive slip ring 3.3 is installed inside the orientation shaft 3.5, and its other side is connected to an optical path conduit. The photoelectric encoder 3.4 is installed on the turntable housing 1 above the conductive slip ring 3.3. The function of the photoelectric encoder 3.4 is to measure the rotation angle and rotation speed of the orientation shaft 3.5.

[0053] The azimuth rotation process is driven by the azimuth motor 3.1. The azimuth motor stator 3.1.1 is fixedly connected to the base 2, keeping the azimuth motor stator 3.1.1 stationary. The azimuth motor rotor 3.1.2 is fixedly connected to the azimuth shaft 3.5. The azimuth shaft 3.5 is fixedly connected to the turntable housing 1. The turntable housing 1 is connected to load 1 5.1, load 2 5.2 and radar lifting platform 6. During the azimuth rotation process, the azimuth motor rotor 3.1.2 drives the azimuth shaft 3.5, the turntable housing 1, load 1 5.1, load 2 5.2 and radar lifting platform 6 to move synchronously.

[0054] The angular contact ball bearing assembly 3.2 consists of two opposing angular contact ball bearings installed between the turntable housing 1 and the azimuth axis 3.5.

[0055] The angular contact ball bearing assembly 3.2 uses two angular contact ball bearings placed opposite each other. This bearing combination not only ensures the stability of the shaft system, but also reduces the space occupied. In addition, it is equipped with an optical path to meet the detection requirements. Both the azimuth and pitch rotation mechanisms can achieve 360-degree continuous rotation. The pitch rotation mechanism can achieve rotation in the range of -85° to 90°, which is convenient for detection requirements.

[0056] It also includes a pitch axis locking device 8, which includes a lock body 8.1, a driver 8.2, a latch 8.3, a contact switch 8.4, and a lock hole 8.5. The driver 8.2, the latch 8.3, and the contact switch 8.4 are all installed in the lock body 8.1. There are two lock bodies 8.1, which are respectively installed on the U-shaped structure of the turntable housing 1. The lock hole 8.5 is installed on both sides of the load 5.

[0057] The pitch locking process is initiated by the pitch drive mechanism 4, which drives load 5.1 and load 5.2 to the designated position. The driver 8.2 then drives the latch 8.3 to extend. The latch 8.3 is inserted into the lock hole 8.5 until it touches the contact switch 8.4, at which point the drive stops and the locking is completed.

[0058] It also includes a pitch limiting device 7, which includes four baffles 7.1. The four baffles 7.1 are divided into two groups and placed symmetrically on both sides of the turntable housing 1. Each group of two baffles 7.1 are respectively installed on the turntable housing 1 and the pitch axis 4.4 or the pitch axis 4.5.

[0059] The pitch limiting device 7 operates by fixing the baffle 7.1 on the turntable housing 1, while the baffle 7.1 on the pitch axis 4.4 and the pitch axis 4.2 moves with the load 5.1 and the load 5.2, and the device is limited by the collision of the two baffles 7.1.

[0060] It also includes an azimuth axis locking device 9, which includes a lock body 9.1, a driver 9.2, a latch 9.3, a contact switch 9.4, and a lock hole 9.5. The driver 9.2, the latch 9.3, and the contact switch 9.4 are all installed in the lock body 9.1, which is mounted on the turntable housing 1, and the lock hole 9.5 is mounted on the base 2.

[0061] The directional locking process is initiated by the directional drive mechanism 3, which drives the turntable housing 1 to rotate to the designated position. The turntable housing 1 then drives the locking tongue 2 9.3 to extend. The locking tongue 2 9.3 is inserted into the locking hole 2 9.5 until it touches the contact switch 2 9.4, at which point the drive stops and the locking is completed.

[0062] It also includes an optical path system 10, which comprises a protective housing 10.1, optical path pipe one 10.2, optical path pipe two 10.3, optical path pipe three 10.4, Coud mirror one 10.5, Coud mirror two 10.6, Coud mirror three 10.7, Coud mirror four 10.8, and Coud mirror five 10.9. The protective housing 10.1 is installed on the unloaded side of the turntable housing 1. Optical path pipe one 10.2 is installed in the center inside the azimuth axis 3.5 and connected to the conductive slip ring 3.3. Mirror 10.5 is installed below 0.2, and Mirror 20.6 is installed above it. Mirror 20.6 is connected to Optical Path Pipe 210.3. Optical Path Pipe 210.3 is connected to Mirror 310.7. Mirror 310.7 is connected to Optical Path Pipe 310.4. Optical Path Pipe 310.4 is connected to Mirror 410.8. Mirror 410.8 is mounted on Turntable Housing 1 and hinged to Pitch Axis 14.4. Mirror 510.9 is mounted on Turntable Housing 1 and hinged to Pitch Axis 24.5.

[0063] During the operation of the optical path, the light enters through Couder Mirror 10.5, passes through Optical Path Pipe 10.2 to Couder Mirror 20.6, is reflected by Couder Mirror 20.6, passes through Optical Path Pipe 20.3 to Couder Mirror 30.7, is reflected by Couder Mirror 30.7, passes through Optical Path Pipe 30.4 to Couder Mirror 40.8, and is reflected by Couder Mirror 40.8 through Pitch Axis 14.4, Load 15.1, and Pitch Axis 24.5 to Couder Mirror 50.9, which then provides laser support to Load 25.2.
