Abstract
The utility model discloses an electromagnetic wave transmitting and receiving device for tunnel investigation, which comprises a base, a first telescopic rod and a locking piece, a radar instrument is mounted on the base, supporting shafts are mounted on the left side and the right side of the base, four limiting rings and two rollers are sleeved on the supporting shafts, and sleeves and inserting rods are respectively arranged on the side surfaces of the two rollers. The first telescopic rod is rotatably provided with a second telescopic rod, the lower ends of the first telescopic rod and the second telescopic rod are rotatably connected with the base through a hinge seat, and the locking piece is installed on the first telescopic rod and the second telescopic rod; the limiting rings limit sliding of the rolling wheels on the supporting shafts, the four rolling wheels can be located at the four corners of the base, it is guaranteed that the base cannot incline, when a radar instrument is used for underground detection, stability is good, the two rolling wheels are spliced into the wide wheel through the rods and the sleeves, the trafficability of moving of the base is improved, and the radar instrument can cope with the ground with broken stones, broken soil and many potholes and is flexible to use. And underground detection can be carried out on complex terrains.
