Description

Technical Field

[0002] Radar is an electronic device that uses electromagnetic waves to detect targets. It emits electromagnetic waves, which are reflected when they encounter target objects. The radar receives the reflected electromagnetic waves and analyzes and processes them to obtain information such as the target's position, speed, shape, and size.

[0003] Although the traditional radar fixed gimbal has the effect of fixing the radar, it does not have the effect of lifting and lowering. The height of the fixed gimbal is fixed, so it is not convenient to adjust the height of the radar, and it is difficult to obtain a better detection angle or avoid obstruction. At the same time, it is not convenient to lower the radar for maintenance. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 The liftable radar fixed pan-tilt platform includes a mounting base 1, an mounting box 2 is fixedly mounted on the upper end surface of the mounting base 1, two limit grooves 18 are symmetrically provided on the upper end surface of the mounting box 2, a lifting device is provided on the bottom wall of the mounting box 2, two mounting holes 10 are symmetrically provided on the output end of the lifting device, a trigger device is provided in each mounting hole 10, the output end of the lifting device passes through the inner top wall of the mounting box 2 and extends outward to be installed with a mounting plate 4, the lower section of the mounting plate 4 is symmetrically fixedly installed with two limit devices, and the output ends of the two limit devices both pass through the limit grooves 18 corresponding in position and extend into the mounting box 2.

[0023] The lifting device includes a motor 5, and the motor 5 is fixedly installed on the inner bottom of the installation box 2. A threaded rod 9 is fixedly installed on the output shaft of the motor 5. The threaded rod 9 is threadedly connected to a sleeve 8, and mounting holes 10 are symmetrically opened on the outer wall of the sleeve 8. One end of the sleeve 8 passes through the inner top wall of the installation box 2, and the mounting plate 4 is fixedly installed on the upper end surface of the sleeve 8. The threaded rod 9 can be rotated by the motor 5, and the sleeve 8 can be lifted and lowered on the threaded rod 9 by the rotation of the threaded rod 9 and the cooperation of the limiting device.

[0024] Each trigger device includes a mounting sleeve 13, and the mounting sleeve 13 is fixed in the mounting hole 10, a piston 16 is slidably connected to the inner wall of the mounting sleeve 13, a fixing rod 12 is fixedly mounted on one end of the piston 16, a spring 17 is sleeved on the outer wall of the fixing rod 12, and two ends of the spring 17 are respectively fixedly connected to the inner wall of the mounting sleeve 13 and one side of the piston 16, the fixing rod 12 can be pushed by the protrusion 11, and the fixing rod 12 pushes the lubricating fluid in the mounting sleeve 13 to the threaded rod 9 through the piston 16, and the spring 17 will be stretched when the piston 16 moves, and when the protrusion 11 is away from the fixing rod 12, the spring 17 will be reset, and the reset of the spring 17 can drive the piston 16 to reset synchronously.

[0025] A semipermeable membrane 15 is fixedly mounted on one end of the mounting sleeve 13 , and the semipermeable membrane 15 can penetrate the lubricating liquid into the threads of the threaded rod 9 . A one-way pipe 14 is connected to the outer wall of the mounting sleeve 13 . It should be noted that the lubricating liquid can be injected into the mounting sleeve 13 through the one-way pipe 14 .

[0026] Each limiting device includes a limiting rod 6, and the limiting rod 6 is fixedly installed on the lower end surface of the mounting plate 4, and one end of the limiting rod 6 passes through the limiting groove 18 and extends into the mounting box 2, and a plurality of protrusions 11 are fixedly installed at equal intervals on the outer wall of the limiting rod 6, and a limiting block 7 is fixedly installed on the bottom end of the limiting rod 6. It should be noted that: the two limiting rods 6 can limit the mounting plate 4. Since the mounting plate 4 is fixedly installed on the upper end surface of the sleeve 8, the sleeve 8 can be synchronously limited by the two limiting rods 6, and the two limiting blocks 7 can limit the limiting rod 6 to prevent the limiting rod 6 from detaching from the mounting box 2.

Since two limit rods 6 are symmetrically fixedly installed on the lower end surface of the mounting plate 4, the two limit rods 6 can limit the mounting plate 4 and the sleeve 8. When the motor 5 is started, the output shaft of the motor 5 will drive the threaded rod 9 to rotate, and then the threaded rod 9 will drive the sleeve 8 to move on the threaded rod 9. At the same time, the mounting plate 4 will move synchronously with the sleeve 8. At this time, the lifting and lowering of the radar can be completed, and the limit rod 6 will slide in the limit groove 18.

[0029] When the limit rod 6 slides in the limit groove 18, the protrusion 11 on the outer wall of the limit rod 6 will abut against the fixed rod 12. At this time, the fixed rod 12 will drive the piston 16 to slide in the mounting sleeve 13. At the same time, the spring 17 will be stretched by the piston 16. At this time, the lubricating fluid in the mounting sleeve 13 will penetrate out of the mounting sleeve 13 through the semipermeable membrane 15 under the compression of the piston 16. At this time, the threaded rod 9 can be lubricated. When the protrusion 11 no longer abuts against the fixed rod 12, the spring 17 will reset. At this time, the piston 16 will reset following the spring 17, and the fixed rod 12 will move synchronously with the reset of the piston 16.
