Description

Technical Field

[0001] This utility model relates to the field of radar detection technology, and more specifically, to a fast-moving trolley for a phased array deep-earth detection radar. Background Technology

[0002] Phased array deep-earth radar is an advanced detection system that uses phased array technology to achieve high-precision imaging of underground structures. It achieves rapid beam scanning and focusing by electronically controlling the phase of each element in the array antenna, covering areas at different angles without the need for mechanical antenna rotation. Compared to traditional radar, its scanning speed and flexibility are significantly improved. It can accurately identify underground rock strata structures, fault distributions, and cavity locations, providing real-time geological data support for tunnel construction and thus reducing engineering risks.

[0003] Some deep-earth exploration equipment typically uses two antennas, mounted spaced apart on a frame. Rollers are also installed on the frame to facilitate movement of the entire device on the ground during exploration. Before exploration, both antennas must be brought into contact with the ground, and then the frame can be moved to begin deep-earth exploration. Because the soil hardness varies in different exploration areas, when the exploration device is placed on the ground, if the soil is soft, the rollers will sink to a certain depth. In this case, the antenna height needs to be adjusted to ensure it is in contact with the ground. However, existing technology for this type of device still has the technical problem of inconvenient and slow adjustment of the antenna height. Utility Model Content

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example 1

[0020] Please see Figure 1 and Figure 2 This embodiment provides a technical solution:

[0021] A fast-moving trolley for a phased array deep-earth detection radar includes a frame 101 and several wheels 201 mounted on the frame 101. Each wheel 201 is equipped with an odometer or odometer (not shown in the figure). In this embodiment, there are four wheels 201. A handle (not shown in the figure) is also installed at one end of the frame 101 to facilitate pushing the frame 101. Two sets of lifting mechanisms are installed at intervals on the frame 101. An antenna 301 is mounted on the actuator end of any lifting mechanism. The two sets of lifting mechanisms are used to control the distance between the two antennas 301 and the ground.

[0022] In this embodiment, a crossbar 401 is slidably mounted on the frame 101, the antenna 301 is mounted on the crossbar 401, and the lifting mechanism is connected to the crossbar 401 via a transmission mechanism. Figure 2 From this perspective, the horizontal bar 401 can slide up and down in the vertical direction.

[0023] Specifically, in this embodiment, the lifting mechanism is an adjusting screw 501 that is threadedly connected to the frame 101. One end of the adjusting screw 501 is rotatably connected to the crossbar 401. The central axis of the adjusting screw 501 is parallel to the sliding direction of the crossbar 401, and the crossbar 401 is located between the adjusting screw 501 and the antenna 301.

[0024] When using this device for deep-earth exploration on surfaces of varying hardness, after placing the trolley, screw the two adjusting screws 501 until the two antennas 301 contact the ground, and the exploration work can begin.

[0025] In other embodiments of this example, the device can be moved on the ground (including underground in mines) by being dragged by other mechanical equipment, without manual dragging. The equipment can be fixed and supported by a robotic arm, and the carrier can be various forms of carrier such as a coal mining machine, a tunneling machine, a roadheader, or a tracked self-propelled vehicle.

[0026] Example 2

[0027] Please see Figure 3 The difference between this embodiment and embodiment one is that: in this embodiment, a crossbeam 601 is installed on the frame 101 above the crossbar 401, and a first connecting rod 701 passes through the crossbeam 601. One end of the first connecting rod 701 is connected to the crossbar 401, and the length direction of the first connecting rod 701 is parallel to the sliding direction of the crossbar 401; a plurality of through holes 702 are linearly arranged on the crossbar 401, and the arrangement direction of the plurality of through holes 702 is parallel to the sliding direction of the crossbar 401. A pin 703 is detachably connected in one of the through holes 702.

[0028] Before detection, if the height of antenna 301 needs to be adjusted, first remove the two pins 703, then let the two antennas 301 fall to the ground under the action of gravity, and then insert the two pins 703 into the corresponding two through holes 702 respectively.

[0029] If the ground in the detection area is flat, a pin 703 can be installed in each of the two through holes 702 on the upper and lower surfaces of the crossbeam 601. This way, the antenna 301 will not be displaced in the vertical direction during the movement of the trolley.

[0030] Example 3

[0031] Please see Figure 4 The difference between this embodiment and Embodiment Two is that in this embodiment, the bottom ends of the two first connecting rods 701 are respectively connected to the two antennas 301, and the top ends of the two first connecting rods 701 are connected through the second connecting rod 801; a pin 703 is detachably connected to one of the through holes 702 on one of the first connecting rods 701. When the pin 703 is removed, the two first connecting rods 701 can be moved simultaneously by moving the second connecting rod 801, so that the height of the antenna 301 does not need to be adjusted by operating the two first connecting rods 701 separately.
