[0033] Two groups of bracket joints 506 are arranged at the top of the antenna bracket 5, an upper fixing ring 501 and a lower fixing ring 502 are arranged at the top of the antenna bracket 5 through the bracket joints 506, a bracket fixing ring 503 is arranged at the bottom of the antenna bracket 5, support rod slide grooves 505 are opened on both sides of the antenna bracket 5, bracket support rods 507 are arranged on both sides of the antenna bracket 5 through the support rod slide grooves 505, and a support rod fixing ring 504 is arranged at one end of the bracket support rod 507 away from the antenna bracket 5.

[0035] The antenna bracket 5 is movably set above the supporting upper plate 3 near one side through the bracket fixing ring 503 and the fixing rod 2 302. One end of the bracket support rod 507 is movably set with the supporting upper plate 3 through the support rod fixing ring 504 and the fixing rod 1 301. The end of the bracket support rod 507 away from the supporting upper plate 3 slides up and down along the support rod slide groove 505.

[0036] When in use, the radar antenna 801 is fixed by the upper fixing ring 501 and the lower fixing ring 502, and the radar antenna 801 is set at one side of the antenna bracket 5. The antenna bracket 5 is rotated clockwise around the fixing rod 2 302 through the bracket fixing ring 503. During this process, the bracket support rod 507 moves along the support rod sliding groove 505 to a position close to the bottom of the antenna bracket 5, so that the bracket support rod 507 rotates clockwise around the fixing rod 1 301 through the support rod fixing ring 504, wherein the bracket support rod 507 can provide support force for the antenna bracket 5, effectively improving the stability of the antenna bracket 5.

Then the wire 802 is passed through the threading hole 304. Through the above operation, the radar antenna 801 can be supported during measurement, which is more labor-saving and does not require the staff to hold it.

[0037] Example 2

[0038] See also Figure 1-5The present invention provides a technical solution: a movable radar antenna bracket for a tunnel, comprising a supporting lower plate 2 and a supporting upper plate 3, a hydraulic jack 1 is arranged at the bottom of the supporting lower plate 2, a placing platform 6 is arranged on the left side of the supporting lower plate 2, universal wheels 4 are arranged at the bottom of the supporting lower plate 2 near the corners, and an antenna bracket 5 is arranged at the upper end of the supporting upper plate 3 near one side;

[0039] It also includes a radar antenna 801 located at the upper end of the placement platform 6 , a wire 802 is set on one side of the radar antenna 801 , and a connector 9 is set between the radar antenna 801 and the placement platform 6 .

[0040] An upper plate limiting rod 7 is provided near the corner of the upper end of the supporting lower plate 2, and a stabilizing plate 101 is provided at the bottom of the supporting upper plate 3 and in the middle.

[0041] The lifting shaft of the hydraulic jack 1 passes through the support lower plate 2 and is fixedly connected to the bottom of the stabilizing plate 101. The upper surface of the support upper plate 3 is provided with a limiting groove that matches the upper plate limiting rod 7 near the corner. The support upper plate 3 cooperates with the hydraulic jack 1 to slide up and down along the upper plate limiting rod 7 through the upper plate limiting rod 7, the stabilizing plate 101 and the limiting groove.

[0042] Specifically, when mobile measurement is required, the universal wheel 4 arranged near the corner position at the bottom of the supporting lower plate 2 can facilitate the staff to push the radar antenna bracket to move, and then facilitate the staff to move the radar antenna 801 to a suitable measurement position according to the measurement needs, which is more convenient. The hydraulic jack 1 applies an upward thrust to the supporting upper plate 3, wherein the stabilizing plate 101 can play a supporting role in the movement of the supporting upper plate 3, thereby increasing the stability between the lifting shaft of the hydraulic jack 1 and the supporting upper plate 3. At this time, the supporting upper plate 3 moves upward along the upper plate limiting rod 7 through the limiting groove, wherein the upper plate limiting rod 7 can play a plane limiting function when the supporting upper plate 3 moves, thereby improving the stability of the supporting upper plate 3, and then the radar antenna 801 placed on the antenna bracket 5 can be moved upward. Raising the height of the radar antenna 801 can be used to measure positions at different heights, effectively increasing the measurement range of the radar antenna 801.

[0043] The working principle of the radar antenna bracket is as follows: the radar antenna 801 is fixed by the upper fixing ring 501 and the lower fixing ring 502, and the radar antenna 801 is set at one side of the antenna bracket 5. The antenna bracket 5 is rotated clockwise around the fixing rod 2 302 through the bracket fixing ring 503. During this process, the bracket support rod 507 moves along the support rod slide groove 505 to the position close to the bottom of the antenna bracket 5, so that the bracket support rod 507 rotates clockwise around the fixing rod 1 301 through the support rod fixing ring 504, wherein the bracket support rod 507 can provide supporting force for the antenna bracket 5, effectively improving the stability of the antenna bracket 5. Similarly, the antenna bracket 5 can be rotated counterclockwise, so that the inclination angle of the antenna bracket 5 can be adjusted, so that the radar antenna 801 is close to the palm face, and the inclination angles of the upper fixing ring 501 and the lower fixing ring 502 can be adjusted through the bracket joint 506, thereby adjusting the radar antenna 80 1 plane to make it parallel to the tunnel face, then place the radar screen on the placement table 6, and fix the radar screen and the placement table 6 through the connector 9. Then pass the wire 802 through the threading hole 304 to connect with the radar screen, and the universal wheel 4 arranged at the bottom of the supporting lower plate 2 near the corner position can facilitate the staff to push the radar antenna bracket to move, and the hydraulic jack 1 applies an upward thrust to the supporting upper plate 3, wherein the stabilizing plate 101 can play a supporting role in the movement of the supporting upper plate 3, and increase the stability between the lifting shaft of the hydraulic jack 1 and the supporting upper plate 3. At this time, the supporting upper plate 3 moves upward along the upper plate limiting rod 7 through the limiting groove, wherein the upper plate limiting rod 7 can play a plane limiting function when the supporting upper plate 3 moves, thereby improving the stability of the supporting upper plate 3, and then the radar antenna 801 placed on the antenna bracket 5 can be moved upward, and the height of the radar antenna 801 is raised for measuring positions at different heights.
