Convenient tunnel detection platform

Abstract

The invention provides a convenient tunnel detection platform. A base is arranged in the middle of a vehicle body. A telescopic frame is arranged above the base. A platform is arranged at the top of the telescopic frame. A radar antenna device is arranged on one side of the platform. The radar antenna device comprises a seat body. The seat body is connected with an antenna connection rod through a rotation telescopic part. The antenna connection rod comprises a rod body. The upper end of the rod body is connected with a round groove seat. A ball connection part is arranged in the round groove seat. The upper end of the ball connection part is connected with an antenna mounting plate. A round hole with internal thread is arranged at the center of the antenna mounting plate. The tail end of the antenna connection rod is connected with an antenna box. A roller device is arranged on the side of the antenna box. A sleeve is arranged on the lower edge of the side. A spring is arranged in the sleeve. A handle is arranged in the middle of the antenna connection rod. A head lamp is arranged on the platform. The tunnel detection platform can replace the method of holding an antenna with hand. The direction of a control antenna is adjusted. The lighting device whose angle can be freely adjusted is arranged to meet lighting needs. Through the antenna connection rod, the radar antenna can be rotated in any direction to meet different angle needs of tunnel measurement.

Description

technical field [0001] The invention relates to the technical field of tunnel detection, in particular to a convenient tunnel detection platform. Background technique [0002] In the lining detection of tunnels, the combination of geological radar and radar antennas of different frequencies is mainly used. The geological radar antenna is closely attached to the lining surface, and the radar antenna emits electromagnetic waves into the interior of the lining. When encountering different media, the electromagnetic waves will be reflected and then detected by the radar The antenna accepts and produces different detection images. This principle determines that the radar antenna must be closely attached to the lining surface, otherwise interference reflections will occur in places where the bonding is not good, and the detection results will be affected. The environment inside the road tunnel is relatively complex, such as tunnel wires, road obstacles, and the height difference ...

This principle determines that the radar antenna must be closely attached to the lining surface, otherwise interference reflections will occur in places where the bonding is not good, and the detection results will be affected

The environment in the tunnel of the road tunnel is relatively complicated, such as tunnel wires, road obstacles, and the height difference between the road surface and the detection line is inconsistent, so that the detection of the road tunnel cannot be like a railway tunnel, where the detection vehicle or the detection frame is placed on the rails, and there is a relatively uniform Elevation, no other interference, the current road tunnel is mainly the way of manually lifting the antenna, and the antenna is close to the lining surface to ensure that the radar antenna is closely attached to the lining surface to ensure the detection effect, but the way of manually lifting the line will cause arm soreness, It cannot work for a long time, which affects the detection efficiency. The current detection platform also lacks lighting equipment, and it cannot meet the lighting requirements if it is close to the lights. People on the platform cannot see the situation ahead and are easily scratched, bruised or hit by the platform. to fans, etc., and even safety accidents; on the other hand, at this stage, wooden sticks or other rods are basically used to wrap wires on the connector of the antenna, or to connect with screws, which is troublesome to disassemble; wooden sticks or other connecting rods cannot be rotated , while the tunnel lining is generally arc-shaped, the angle of the arch waist and the vault are different, and it is basically adjusted by the person. It is difficult to maintain a comfortable posture and is prone to fatigue, which is not conducive to long-term inspection.

At present, manual operation, depending on the physique of the operator, can only detect 100-200m at a time. For long and extra-long tunnels, the detection work will become very scattered and discontinuous
