Description

Technical Field

[0001] The utility model relates to the field of airport technical equipment, in particular to an integrated and movable airport taxiway area closing marking device. Background Art

[0002] The taxiway closure sign is one of the common signs on the airport pavement. According to the requirements of the "Technical Standards for Civil Airport Airfields MH5001-2013", the size of the closure sign used on the taxiway should be 1.5m long and 0.9m wide. In actual operations, taxiways generally use ground signs to indicate the closure status. In special cases, a trolley with a closure sign will be equipped to serve as an auxiliary indicator.

[0003] Ground markings must be set up by spraying yellow marking paint. After the taxiway is opened, high-pressure water line removers, shot blasting line removers and physical high-temperature line removers must be used for removal.

[0004] However, in actual operations, each of the above removal methods has its own shortcomings. From the perspective of operation methods, high-temperature physical wire removal has low efficiency, with about 5 square meters of wire removed per hour; during the wire removal operation, the paint that has been re-washed by the high-pressure water gun is very easy to contaminate the pavement if it is not properly handled, and it also damages the caulking material in the pavement. In addition, after removing the markings, there is a high possibility of foreign object debris (FOD) in the flight area, which may damage aircraft and equipment or threaten the lives of airport staff and passengers, causing flight hazards. From the perspective of operation efficiency, the spraying and removal operations of ground markings are relatively long, which seriously affects the speed of taxiway restoration. Multiple spraying and removal operations will lead to increased manpower and material costs, as well as irreversible damage to the taxiway, resulting in increased maintenance costs.

[0005] The trolley with a closed sign has an upright X-shaped closed sign that can be used to indicate at night. However, the angle of the closed sign cannot be adjusted, resulting in the closed sign sprayed on the ground and the closed sign on the trolley indicating different directions. In addition to the operator, the trolley must also be pulled to the target position by a device with a power system before it can be used, which also increases the complexity of setting a single closed sign.

[0006] Therefore, based on the existing situation, the utility model proposes an integrated closing identification device that does not generate FOD and can adjust the indication angle. Summary of the invention

[0007] The utility model aims to provide an integrated movable airport taxiway area closure marking device, which can complete the pavement closure warning operation without generating FOD, thereby ensuring the safety of aircraft, equipment, airport staff and passengers in the area.

[0008] The utility model discloses an integrated movable airport taxiway area closure marking device, which is composed of a vehicle frame, a wheel group, a battery group, an obstacle light, and a closure sign, wherein:

[0009] The vehicle body frame is a hollow frame structure constructed of supportable rods;

[0010] The wheel set is arranged under the vehicle body frame, and the wheel set comprises a rotating shaft and a wheel;

[0011] The battery pack is arranged in the vehicle frame, parallel to the ground, and is connected to the obstacle light and the closing sign to supply power to them;

[0012] The obstacle light is composed of a column and a lamp body, one end of the column is rotatably connected to the vehicle frame, and the other end is provided with the lamp body so that the lamp body can rotate with the column as the axis;

[0013] The end of the closing sign on the same side is rotatably connected to the vehicle body frame, so that the closing sign can rotate along the connection.

[0014] Furthermore, the wheel group also includes a spring buckle, and the rotating shaft is connected to the vehicle body frame through the spring buckle. When the airport taxiway area closing sign vehicle moves, the spring buckle is locked and the wheels remain upright. When the closing sign is set up, the spring buckle is pressed and the wheels fold inward.

[0015] Preferably, the obstacle light is hinged to the vehicle body frame.

[0016] Preferably, the closing sign is an X-shaped sign, and two bottom corners of the closing sign are hinged to the vehicle body frame.

[0017] In order to reduce the wind resistance and space occupation of the vehicle body frame, the vehicle body frame is a triangular prism, in which a quadrilateral surface is used as the bottom surface, and the battery pack is mounted in the frame where the bottom surface is located.

[0018] The wheels are provided with brake pads to meet the needs of temporary parking.

[0019] In terms of its own structure, the wheels can be upright or folded. The wheels can be folded after moving using the wheel group, which increases the overall stability of the device. The battery pack can not only power the obstacle lights and shutdown signs of the device, but also increase the weight of the vehicle frame, so that it will not change position due to external forces during movement or operation.

[0020] In terms of actual operating results, the device described in the utility model can be used both during the day and at night. The obstacle lights and the close signs can be kept upright or placed at a specific angle. All structures in the device are connected, so that there is no FOD throughout the entire movement and operation, ensuring the safety of aircraft, equipment, airport staff and passengers in the area.
