Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1-2 As shown: A radar antenna adaptability mounting frame device includes a mounting frame 1 installed and suspended at the front or rear of a road compaction device. The upper and lower sides of the mounting frame 1 are open sides, and the side wall is composed of multiple crossbars 11. The crossbars 11 corresponding to each side wall are arranged sequentially from bottom to top and are parallel to each other. The crossbars 11 are of slat structure and have multiple mounting holes 12 in the corresponding length direction.

[0023] A wooden board 2 is installed on the lower opening side of the hanging frame 1 to support the radar antenna. The hanging frame is a metal structure, which has better structural stability and support. The wooden board on the lower side will not affect the energy of the electromagnetic pulse wave of the radar antenna when supporting it.

[0024] The hanging frame 1 is equipped with a clamping device, which includes a clamping plate 3. One side of the clamping plate 3 is the clamping side, and the other side is equipped with a screw 4 in the center. One end of the screw 4 is a ball shaft 41. The clamping plate 3 has a ball groove 31 for sleeved ball shaft 41. The other end of the screw 4 is used to pass through the mounting hole 12 and be fixed by a nut 42.

[0025] The radar antenna is held in place by clamping devices to prevent it from shifting or swaying in the hanging frame. Multiple clamping devices work simultaneously to fix the radar antenna. Each clamping device contacts one side of the radar antenna through a clamping plate, while the clamping devices corresponding to the radar antenna are located on the opposite side and work simultaneously. The screw end on the back of the clamping plate is a ball joint that can be adjusted to fit the ball groove, allowing the angle of the clamping plate to be adjusted according to the irregular shape of the radar antenna sidewall.

[0026] The other end of the screw passes through the mounting hole, and by rotating the nut, the end of the screw pushes the clamping plate to squeeze the radar antenna, thus completing the clamping process.

[0027] like Figure 2 As shown: The ends of the crossbars 11 corresponding to adjacent side walls are fixed to the same column 13. The bottom of the column 13 has an arc-shaped support plate 14 for supporting the corner of the wooden board 2. The arc-shaped structure of the support plate is a quarter-circle arc structure for supporting the wooden board.

[0028] The spring 15 is installed at the corner position of the wood board 2, the support plate 14 is provided with a positioning block 16 for sleeving the lower end of the spring 15, and the corner position of the wood board 2 is provided with a positioning sleeve 21 for sleeving the spring 15. The positioning block is sleeved in the spring and is used for fixing the spring, and the positioning sleeve is fixed to the template and is used for sleeving the outside of the spring, is elastically supported by the spring, helps to absorb the vibration energy transmitted by the wood board, reduces the influence of mechanical vibration during the running of the road compaction equipment, and provides detection accuracy.

[0029] The clamping plate 3 is fixed with an elastic pad layer 32 on the clamping side. The elastic pad layer is made of rubber, sponge or the like, is used for soft contact with the radar antenna shell, improves the clamping stability, and reduces the influence of equipment vibration on radar antenna detection.
