Description

Technical Field

[0001] The utility model relates to an array antenna loading vehicle, belonging to the technical field of loading vehicles. Background Art

[0002] Transient electromagnetic systems (TEMs) are a nondestructive detection technology that uses antennas to emit high-frequency pulsed electromagnetic waves toward the target. Compared to other conventional underground detection methods, TEMs offer advantages such as high speed, continuous detection, high resolution, convenient and flexible operation, and low cost. Their application in engineering surveys is growing. In actual engineering applications, long sections of highway are often surveyed. To improve efficiency, antenna loader trucks are typically towed by motor vehicles. However, a single antenna often falls short of detection requirements, and array antennas are often designed for more precise detection. However, because array antennas integrate multiple antenna groups, they weigh over 100 kg, making them difficult for conventional loader trucks to bear.

[0003] Chinese patent publication number CN216434363U discloses a ground-penetrating radar loading vehicle, comprising a main body; a front right universal wheel and a front left universal wheel are mounted on one side of the lower end of the main body, and a rear right fixed wheel and a rear left fixed wheel are mounted on the other side; a small gantry is mounted on one side of the upper end of the main body, and a large gantry is mounted on the other side, connected to the large gantry via a strap; and a vehicle buckle is connected to one end of the main body via a pull rod. This loading vehicle minimizes interference near the radar and allows for adjustment of the distance between the radar bottom and the ground.

[0004] However, the loader uses straps to adjust the distance between the radar and the ground, and also ties the radar to the loader via straps. This flexible fixing method causes the radar to shake or swing significantly when detecting the road surface, thus interfering with the radar's detection of the road surface. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the described solution.

[0023] like Figure 1 and Figure 2 As shown, the array antenna loading vehicle described in the present invention includes a steel structure main frame 3 and an array antenna radar 13. The steel structure main frame 3 is provided with a towing connection assembly, and the bottom of the steel structure main frame 3 is provided with a moving wheel group and a spiral elevator 5. The array antenna radar 13 is located at the bottom of the spiral elevator 5. When in use, the steel structure main frame 3 is welded with high-strength steel pipes and can carry equipment weighing up to one ton. When towed by a motor vehicle, the speed can reach 50 km / h, which can meet its load-bearing requirements for the array antenna radar 13. The array antenna radar 13 is installed at the bottom of the spiral elevator 5, so that the array antenna radar 13 will not shake or swing significantly when detecting the road surface 9. The height of the array antenna radar 13 above the ground is adjusted by the spiral elevator 5, which is convenient to adjust and can continuously and linearly adjust the height of the array antenna radar 13 above the ground within a certain range.

[0024] The towing connection assembly includes a fixed seat 2 and a pull rod 1. The fixed seat 2 is fixed on the steel structure main frame 3, and one end of the pull rod 1 is rotatably connected to the fixed seat 2.

[0025] The movable wheel group includes two steering wheels 11 and two directional wheels 8. The two steering wheels 11 are arranged at one end of the bottom of the steel structure main frame 3 close to the towing connection assembly, and the two directional wheels 8 are arranged at one end of the bottom of the steel structure main frame 3 away from the towing connection assembly.

[0026] The two steering wheels 11 are connected via a steering wheel shaft 12 .

[0027] The two directional wheels 8 are connected via a directional wheel axle 10 .

[0028] The spiral elevator 5 includes two lifting mechanisms arranged side by side at the bottom of the steel structure main frame 3.

[0029] The lifting mechanism includes two lifting components, which are correspondingly arranged on both sides of the bottom of the steel structure main frame 3.

[0030] The lifting assembly includes a frame flange 19, a mounting flange 18 and a screw 20. The frame flange 19 is provided at the bottom of the steel structure main frame 3. The mounting flange 18 is installed at the bottom of the frame flange 19 by fasteners. A worm housing 15 and a worm gear housing 17 are provided at the bottom of the mounting flange 18. A worm is provided for rotation in the worm housing 15, and a worm gear is provided for rotation in the worm gear housing 17. The worm gear is engaged with the worm. The screw 20 is arranged vertically and is threadedly connected to the worm gear. The lower end of the screw 20 is provided with a connecting flange 16 for connecting to the array antenna radar 13.

[0031] The worms of the two lifting assemblies of the same lifting mechanism are connected by a linkage shaft 4, which passes through the worms of the two lifting assemblies, and one end of the linkage shaft 4 is provided with a handwheel 14.
