[0020] Reference Figure 1 , Figure 2 and Figure 5 The embodiment of the present application provides a radar head field test platform, including: Radar head 100; The first adjustment device 200 includes a fixed frame 210, a driving assembly and a base frame 270. The radar head 100 is fixed to the fixed frame 210, the fixed frame 210 is hinged to the base frame 270, and the driving assembly is installed on the base frame 270. The driving assembly is used to drive the fixed frame 210 to rotate along the hinge with the base frame 270; The turntable device 300 includes a turntable body 310 and a base 320. The turntable body 310 is installed on the upper side of the base 320. The turntable body 310 is connected to the lower side of the first adjustment device 200. A second adjustment device 400 is provided on the lower side of the base 320. The second adjustment device 400 includes a first adapter plate 410, a bottom plate 440 and a leveling leg assembly 420. The base 320 is installed on the first adapter plate 410. The first adapter plate 410 is hinged to the bottom plate 440. The leveling leg assembly 420 is fixed to the bottom plate 440. The leveling leg assembly 420 is used to drive the first adapter plate 410 to rotate along the hinge with the bottom plate 440.

[0021] It should be noted that during the transportation of the field test platform, the fixed frame 210 is placed flat on the base frame 270, thereby reducing the vertical space occupied by the radar head 100; during the field test of the radar head 100, the first adjustment device 200 is used to achieve angle adjustment between the radar head 100 and the turntable device 300 during the test.

[0022] It should be noted that the base frame 270 includes multiple support rods, which form a network structure, and the center of gravity of the base frame 270 coincides with the rotation center of the turntable device 300, so that the pressure on the base frame 270 is evenly distributed to the turntable device 300 and the stability of the radar head field test platform is ensured.

[0023] It should be noted that when the turntable device 300 is installed on the lower side of the base frame 270, during the transportation of the field test platform, the turntable body 310 is fixed to the base 320, and the turntable body 310 cannot rotate on the base 320; during the testing of the radar head 100, the turntable device 300 drives the base frame 270 to rotate horizontally, thereby driving the radar head 100 to adjust the horizontal angle.

[0024] It should be noted that during the transportation of the field test platform, the first adapter plate 410 is placed flat on the base plate 440, thereby reducing the vertical space occupied by the turntable device 300; during the testing of the radar head 100, the angle between the turntable device 300 and the base plate 440 is adjusted by leveling the leg assembly 420, so that the radar head field test platform is suitable for environments with different slopes.

[0025] It should be noted that the base plate 440 is provided with a hinge seat, and the first adapter plate 410 is provided with a shaft sleeve. The shaft sleeve of the first adapter plate 410 is hinged to the hinge seat of the base plate 440 through a rotating shaft and an axis end baffle, so that the first adapter plate 410 can rotate along the hinge with the base plate 440, and the leveling leg assembly 420 can adjust the angle between the first adapter plate 410 and the base plate 440, thereby adjusting the angle between the turntable device 300 and the base plate 440.

[0026] It should be noted that, during the implementation process, two leveling leg assemblies 420 are provided, and the two leveling leg assemblies 420 are symmetrical about the first adapter plate 410, so that the supporting force of the leveling leg assemblies 420 on the first adapter plate 410 is balanced and stable, thereby ensuring the stability of the radar head field test platform.

[0027] It should be noted that before the transportation of the radar head field test platform, the radar head 100 is fixed to the fixed frame 210, and the radar head 100 is placed flat on the base frame 270 by the driving assembly, thereby reducing the vertical space occupied by the radar head 100; the turntable device 300 is locked so that the turntable body 310 cannot rotate on the upper side of the base 320; the first adapter plate 410 is placed flat on the bottom plate 440 by the leveling leg assembly 420, thereby reducing the vertical space occupied by the turntable device 300. The radar head field test platform is moved to the transportation tool. Since the first adjustment device 200 and the second adjustment device 400 reduce the vertical space occupied by the radar head 100 and the turntable device 300, the radar head field test platform can pass through height-restricted environments such as elevators, which improves the transportation convenience of the radar head 100 and the turntable device 300. When the radar head field test platform arrives at the test site, the fixed frame 210 is driven by the driving assembly to rotate to the required angle for the test, and the turntable device 300 is unlocked. The turntable body 310 can be rotated on the upper side of the base 320, and the first adapter plate 410 is rotated to the required angle for the test through the leveling leg assembly 420.

[0037] In addition, in one embodiment, referring to Figure 4 The connecting component 260 includes a first hinge joint 261, a fixed block 262 and a rotating column 263. The screw rod 250 is fixed to the first hinge joint 261. The first hinge joint 261 is provided with a groove. The fixed block 262 is arranged in the groove. The fixed block 262 is connected to the first hinge joint 261 through a pin shaft, a gasket and an axis end stopper. The rotating column 263 is penetrated by the fixed block 262. The rotating column 263 can be fixed to the fixed frame 210, and the fixed block 262 can rotate along the rotating column 263.

[0038] It should be noted that the fixed block 262 is hinged to the first hinge joint 261 through a pin shaft, the screw rod 250 can rotate around the pin shaft, the fixed block 262 is fixed to the fixed frame 210 through a rotating column 263, the screw rod 250 can rotate around the rotating column 263, and the connecting component 260 can eliminate the manufacturing error of the radar head field test platform to prevent the screw rod 250 from getting stuck.

When the driving assembly drives the fixed frame 210 to rotate along the hinge with the base frame 270, the rotating column 263 is fixed to the fixed frame 210. In the following embodiment, when the driving assembly drives the connecting frame 275 to slide on the guide rail 272, the rotating column 263 is fixed to the connecting frame 275. When the connecting assembly 260 needs to be fixed in different places, the rotating column 263 can be disassembled and installed to the required position. The rotating assembly 240, the fixed block 262 and the rotating column 263 enable the driving assembly to achieve the effect that one driving assembly can drive multiple assemblies respectively.

The third hinge joint 436 is hinged to the fifth hinge seat 437 through a rotating shaft, a shaft sleeve and a shaft end stopper, and the pipe shaft 435 is hinged to the bottom plate 440 to prevent the auxiliary support assembly 430 from being stuck on the bottom plate 440.

[0049] It should be noted that the fourth hinge seat 431 is fixed to the midline position of the first adapter plate 410, and the fifth hinge seat 437 is connected to the midline position of the base plate 440, so that the support efficiency of the auxiliary support assembly 430 for the first adapter plate 410 is maximized and the force of the first adapter plate 410 is balanced.

[0050] It should be noted that a thread can be set inside the tubular shaft 435, and an oil-free gasket can be set between the tubular shaft 435 and the third hinge joint 436. The oil-free gasket enables oil-free lubrication between the tubular shaft 435 and the third hinge joint 436. By rotating the tubular shaft 435, the tubular shaft 435 is moved along the screw 433, thereby achieving a more precise change in the length of the auxiliary support assembly 430.

[0051] It should be noted that when the length of the auxiliary support assembly 430 needs to be adjusted, first release the fifth hinge seat 437 connected to the base plate 440, loosen the locking nut 434, allow the tube shaft 435 to slide on the outside of the screw 433, and adjust the auxiliary support assembly 430 to the appropriate length by sliding the tube shaft 435. After connecting the fifth hinge seat 437 to the base plate 440, tighten the locking nut 434.

[0052] In addition, in one embodiment, referring to Figure 5 and Figure 7 The leveling leg assembly 420 includes a bottom cup 425, a universal ball shaft 424, a rotating rod 423, an inner tube 422 and an outer tube 421. The inner tube 422 is fixed to the universal ball shaft 424. The universal ball shaft 424 can be rotatably connected to the bottom cup 425. The bottom cup 425 is fixed to the bottom plate 440. The outer tube 421 can be slidably sleeved on the outer side of the inner tube 422. A support rod 450 and a support seat 460 are provided on the outer side of the outer tube 421. The support rod 450 is fixed to the outer tube 421. The support rod 450 is penetrated by the support seat 460. The support seat 460 can rotate along the support rod 450. The support seat 460 is used to support the first adapter plate 410. The rotating rod 423 is connected to the outer tube 421. The rotating rod 423 is used to drive the outer tube 421 to rise and fall along the inner tube 422.

[0053] It should be noted that the universal ball shaft 424 enables the inner tube 422 to rotate in any direction along the universal ball shaft 424. The inner tube 422 drives the outer tube 421 to rotate around the universal ball shaft 424. The outer tube 421 drives the support seat 460 to move along the outer tube 421 through the support rod 450, thereby driving the first adapter plate 410 to rotate along the hinge with the base plate 440, thereby realizing different rotation angles of the first adapter plate 410 and the base plate 440.

[0054] It should be noted that in the implementation, two leveling leg assemblies 420 are provided with respect to the first adapter plate 410, that is, two support seats 460 symmetrical with respect to the first adapter plate 410 are provided to support the first adapter plate 410, and the two support seats 460 can achieve surface contact with the first adapter plate 410 at any time, thereby improving the stability and reliability of supporting the first adapter plate 410.

[0055] It should be noted that the rotary rod 423 is used to drive the inner tube 422 to rotate, thereby driving the outer tube 421 to rotate, and driving the outer tube 421 to slide on the outside of the inner tube 422. The rotary rod 423 can drive the inner tube 422 and the outer tube 421 by hydraulic means, or by a transmission device. This embodiment does not improve the structure of the rotary rod 423, and those skilled in the art can select a specific driving method according to actual needs.

[0056] In addition, in one embodiment, referring to Figure 5 , and also includes: a flat support block 441, the flat support block 441 is fixed to the bottom plate 440, when the outer tube 421 slides to the bottom side of the inner tube 422, the first adapter plate 410 abuts against the flat support block 441, the first adapter plate 410 and the flat support block 441 are both provided with screw holes, and the first adapter plate 410 is fixed to the flat support block 441 by screws.

[0057] It should be noted that, during the implementation process, two flat support blocks 441 are set on the bottom plate 440. During the transportation of the radar head field test platform, the turntable device 300 is placed flat on the bottom plate 440, thereby reducing the vertical space occupied by the turntable device 300. At this time, the flat support block 441 and the first adapter plate 410 are in surface contact, so that the pressure is evenly distributed on the flat support block 441, thereby improving the stability of supporting the first adapter plate 410. The first adapter plate 410 is fixed to the flat support block 441 by screws, thereby fixing the turntable device 300 to the bottom plate 440, avoiding the impact of bumps during transportation on the turntable device 300.

After transporting the radar head field test platform to the test site, loosen the screws fixing the second adapter plate 273 to the base frame 270, drive the screw 250 to move along the axis of the screw 250 through the hand wheel 241, that is, drive the second adapter plate 273 to slide on the guide rail 272, thereby driving the fixed frame 210 to move linearly, and after the center of gravity of the radar head field test platform coincides with the rotation center of the turntable device 300, fix the second adapter plate 273 to the base frame 270 through the screws. Loosen the screws fixing the support leg 220 to the second adapter plate 273, fix the rotating column 263 to the middle position of the top of the fixed frame 210, drive the screw 250 to move along the axis of the screw 250 through the hand wheel 241, thereby driving the fixed frame 210 to rotate along the hinge with the second adapter plate 273, thereby adjusting the angle between the radar head 100 and the turntable device 300. Loosen the screws fixing the first adapter plate 410 to the flat support block 441, loosen the fifth hinge seat 437, adjust the height and angle of the outer tube 421 by the rotating rod 423, thereby adjusting the height and angle of the support seat 460, and rotating the first adapter plate 410 along the hinge with the bottom plate 440. After completing the angle adjustment of the turntable device 300, loosen the locking nut 434, slide the tube shaft 435 on the outside of the screw rod 433, adjust the auxiliary support assembly 430 to the required length, fix the fifth hinge seat 437 to the bottom plate 440, and tighten the locking nut 434 to fix the length of the auxiliary support assembly 430.
