Description

Technical Field

[0001] The present invention relates to a turntable, and more specifically to a T-shaped turntable driven by an outer rotor motor. Background Art

[0002] A turntable is usually used as a support and rotation platform and is widely applied in high-precision measurement fields such as detection, reconnaissance, and geographic mapping. Its main function is to provide a working platform with high stability and accuracy for carrying various professional equipment. At present, with the increasing demand for detection and reconnaissance, designing a real-time, efficient, and multifunctional turntable is an urgent need for the current detection and reconnaissance system.

[0003] Traditional turntable mechanisms often only focus on a specific function, such as only having the ability of optical reconnaissance or only having the ability of radar detection. This single-function design leads to the need for multiple independent systems to work together when facing multiple complex tasks, increasing the complexity and cost of the system and reducing the overall efficiency. Moreover, the data integration between multiple independent detection and reconnaissance devices is a difficult problem. The data formats generated by different devices are inconsistent, making it difficult to perform effective comprehensive analysis and processing. This leads to the phenomenon of information islands, affecting the timeliness and accuracy of decision-making. This design of multiple turntables working together increases the difficulty of transportation and installation, and also increases the maintenance cost of the system. Each repair or replacement of components requires a large amount of time and resources, which is not conducive to long-term stable operation. Such a design not only directly affects the detection accuracy of detection and reconnaissance integration, limits the usage scenarios of the entire mechanism, but also indirectly limits the overall equipment structure design and performance optimization. Summary of the Invention

The beneficial effects are as follows: the pitching motor selects an outer rotor motor, and the two-sided loads are connected through a connecting plate, reducing one driver and improving the synchronization of the two-sided loads at the same time.

[0038] As Figures 1-6 shown, a T-shaped turntable driven by an outer rotor motor includes a base 1, a box body 2, a radar support 3, a load 4, a T-shaped vertical shaft 5, an azimuth drive mechanism 6, a pitch drive mechanism 7, a pitch limit device 8, a pitch locking device 9, and an azimuth locking device 10. The radar support 3 is installed above the T-shaped vertical shaft 5. The load 4 includes a load one 4.1 and a load two 4.2. The loads 4 are respectively installed on both sides of the T-shaped vertical shaft 5. The pitch drive mechanism 7 is installed inside one-sided load 4 and connected to the T-shaped vertical shaft 5 for driving the load one 4.1 and the load two 4.2 to perform pitch motion;

[0039] The pitch drive mechanism 7 includes a pitch motor, a stator two 7.1, a rotor two 7.2, and a connecting plate 7.5. The pitch motor uses an outer rotor motor. The stator two 7.1 is connected to the T-shaped vertical shaft 5. The rotor two 7.2 is connected to the load one 4.1. The load one 4.1 is connected to the load two 4.2 through the connecting plate 7.5, so that the pitch motor drives the load one 4.1 and the load two 4.2 on both sides simultaneously.

[0040] In this application, the pitch motor is selected as an outer rotor motor, and the loads 4 on both sides are connected through the connecting plate 7.5, reducing one driver and improving the synchronization of the loads 4 on both sides at the same time. The loads 4 are placed on both sides of the T-shaped vertical shaft 5 to effectively balance the load and reduce the influence of uneven load on the accuracy of the turntable.

[0041] The pitching rotation process is driven by a pitching motor. The stator two 7.1 of the pitching motor is fixedly connected to the T-shaped vertical shaft 5, so that the stator two 7.1 of the pitching motor follows the T-shaped vertical shaft 5 and remains stationary in the pitching direction. The rotor two 7.2 of the azimuth motor is fixedly connected to the load one 4.1. The load one 4.1 is fixedly connected to the connecting plate 7.5. The connecting plate 7.5 is fixedly connected to the load two 4.2. During the azimuth rotation process, the rotor two 7.2 of the azimuth motor drives the load one 4.1 and the load two 4.2 to move synchronously.

[0042] The main body of the azimuth drive mechanism 6 is installed in the box body 2. The lower part of the box body 2 is installed on the base 1. The azimuth drive mechanism 6 is used to drive the T-shaped vertical shaft 5, the radar support 3, the load one 4.1 and the load two 4.2 to rotate around the vertical direction.

[0043] The pitching drive mechanism 7 further includes an optoelectronic encoder two 7.3 and a deep groove ball bearing 7.4. Both the load one 4.1 and the load two 4.2 are connected to the T-shaped vertical shaft 5 through the deep groove ball bearing 7.4. The optoelectronic encoder two 7.3 is installed between the pitching motor and the load one 4.1.

[0044] The azimuth drive mechanism 6 includes an azimuth motor, a bearing group, a stator one 6.1, a rotor one 6.2, an optoelectronic encoder one 6.3, an angular contact ball bearing 6.4, a conductive slip ring 6.5 and an optical path pipeline 11.1.

[0046] During the optical path operation process, the laser is emitted from the base 1, reflected by the Coudé mirror one 11.2, passes through the optical path pipeline 11.1 and is emitted to the Coudé mirror two 11.3, and is continuously reflected by the Coudé mirror two 11.3 and the Coudé mirror three 11.4 and then enters the load two 4.2 through the T-shaped vertical shaft 5 to provide laser support for the load two 4.2.

[0047] The azimuth rotation process is driven by an azimuth motor. The stator one 6.1 on the azimuth motor is fixedly connected to the box body 2, and the box body 2 is fixedly connected to the base 1, keeping the stator one 6.1 of the azimuth motor stationary. The rotor one 6.2 of the azimuth motor is fixedly connected to the T-shaped vertical shaft 5, and the T-shaped vertical shaft 5 is connected to the two-side loads 4 and the radar support 3. During the azimuth rotation process, the rotor one 6.2 of the azimuth motor drives the T-shaped vertical shaft 5 and the two-side loads 4 and the radar support 3 to move synchronously.

[0048] The bearing group is installed between the box body 1 and the T-shaped vertical shaft 5 by using two relatively placed angular contact ball bearings 6.4. It can bear radial force and axial forces in two directions, improving the stability of the shafting.

[0049] The azimuth motor is a torque motor, which can arrange the optical path pipeline 11.1, the T-shaped vertical shaft 5, the azimuth motor and the box body 2 into concentric circles, making the structure more compact. The T-shaped vertical shaft 5 is installed in the box body 2 by using two relatively placed angular contact ball bearings 6.4. This bearing combination method not only ensures the stability of the T-shaped vertical shaft 5 but also reduces the occupied space.

[0050] The radar support 3 is connected to the T-shaped vertical shaft 5. The radar support 3 and the T-shaped vertical shaft 5 rotate azimuthally together. At the same time, an independent azimuth rotation mechanism is adopted inside the radar support 3 to support the load radar to rotate independently.

The lock body 9.4 is installed above the T-shaped vertical shaft 5, and the locking hole one 9.3 is installed on the side of the load close to the T-shaped vertical shaft 5.

[0052] During the pitch locking process, the pitch driving mechanism 7 drives the load 4 to a specified position, and the driver one 9.1 drives the locking tongue one 9.2 to insert into the locking hole one 9.3 to complete the locking.

[0053] It also includes a pitch limit device 8. The pitch limit device 8 includes a limit plate 8.1 and two baffle plates 8.2.

[0055] The azimuth locking process is that the azimuth driving mechanism 6 drives the T-shaped vertical shaft 5 to rotate to the specified position, and the second driver 10.1 drives the second locking tongue 10.2 to insert into the second locking hole 10.3 to complete the locking.
