The utility model discloses application field is mainly to following four kinds of highway bridges and culverts: 1. small bridges and culverts under construction; 2. small bridges and culverts that have suffered natural disasters (earthquakes, floods, debris flows) or external impacts (vehicle and vessel impacts, etc.); 3. some special small bridges and culverts that need long-term monitoring; 4. the quality of concrete of the upper structure of the highway bridges and culverts in the operating period of the traffic is detected according to relevant regulations of a transportation department; so as to ensure the safe operation of the small bridge and the culvert in the using process of the vehicle. At present, the following methods are generally adopted in the detection of the quality of the upper structure of the small bridge and the culvert: 1. bridge inspection method. The method comprises the steps that a detector detects beam plates, cover beams, rubber supports, support cushion stones, anti-collision check blocks, pull rods and the like of upper structures of a small bridge and a culvert through a detection frame of a small bridge quality detection vehicle; 2. unmanned aerial vehicle method. The method comprises the steps that detection personnel control an unmanned aerial vehicle and detect the structural quality of the upper parts of a small bridge and a culvert by using a camera on the unmanned aerial vehicle; 3. a robotic arm method. The method comprises the steps that a detector controls a mechanical arm, and a camera arranged on the mechanical arm is used for detecting the structural quality of the upper parts of a small bridge and a culvert; 4. climbing method. The method is characterized in that a scaffold or a ladder is erected before detection, and a detector detects beam plates, cover beams, rubber supports, support cushion stones, anti-collision check blocks, pull rods, cover plates and the like of upper structures of small bridges and culverts by climbing the scaffold or the ladder. However, the above method still has the following problems in actual detection work.

According to the relevant national law, the civil unmanned aerial vehicle needs to report to the air management department before flying, the flying height can not exceed 120 meters, and the civil unmanned aerial vehicle can not fly near airports and some military facilities. The mechanical arm method has problems: 1. the position of the defect cannot be accurately positioned, the marking function is lacked, the mechanical arm carries a camera to shoot the defect in the detection process, and the specific position of the defect on the bridge and the culvert cannot be accurately positioned by reexamination personnel and repair personnel due to the lack of the marking function when the defect is found; 2. the later maintenance cost is high, the large-scale popularization and application are not convenient, the use times of the parts such as a motor, an oil pressure system and a battery are limited in the use process of the mechanical arm, and the mechanical arm is easy to damage due to the fact that the later use and maintenance are not in place, so that parts need to be regularly maintained, replaced and replaced in the use process of the mechanical arm; 3. the flexibility of field detection is poor, the working principle of the mechanical arm is that the mechanical arm moves to drive the camera to carry out shooting detection on the small bridge and the culvert member, but the mechanical arm cannot enter the bridge or the culvert for detection when obstacles (such as a water channel, a river bank, a pipeline and the like) exist under the bridge or in the culvert in the field detection process of a construction site; 4. the energy-saving and emission-reducing effects are poor, and the consumed resources are more. When the mechanical arm is used for detection, the mechanical arm device moves to be pulled by a tractor, and part of lanes can be occupied in the detection process, so that the passage of vehicles on the bridge floor is influenced. The climbing method has problems: 1. the method is lack of complete video image record, the appearance quality of the concrete in the detection process can only be detected by visual detection of detection personnel, the related video image data are lacked, the defects and the missing judgment are easy to occur when the detection personnel are tired, and the integral quality of the appearance of the concrete at the upper part of the detected small bridge or culvert cannot be objectively reflected; 2. the detection site has poor adaptability, low working efficiency and is limited by objective conditions; 3. the security is poor, and the testing personnel easily suffer from high altitude accident injury of falling.
