Description

Technical Field

[0001] The present invention belongs to the technical field of apron wells, and specifically relates to a flip-top apron well. Background Art

[0002] The apron is the core area of ​​civil airport transportation operations. This area is used for parking aircraft, boarding and disembarking passengers, loading and unloading cargo, and providing various ground services to aircraft. There are many apron manholes on the apron. The apron manhole covers are used to protect the apron manholes, which can be opened at any time for maintenance operations.

[0003] Manhole covers are installed above the manholes for fire protection, water supply and drainage, cables, valves, etc. in the apron. Operators need to open the manhole covers for maintenance. Manhole covers are heavy, and manhole covers in related technologies usually do not have auxiliary lifting devices, requiring multiple people to collaborate to open and close the manhole covers. Due to the open environment around the airport, the wind speed is high and lasts for a long time. In addition, affected by the airflow of the aircraft, the manhole covers on the apron need to be installed firmly.

[0004] Prior art, patent number; CN204370480U, patent name; flip-up ground well device, discloses a flip-up ground well device, the structure of which includes: hatch bracket, shaft bracket, hatch cover, hatch mounting plate, ground well cover, main frame and balancing device; wherein the main frame is installed above the ground pit that has been poured on the ground, the main frame is equipped with a shaft bracket, the main frame is connected to the hatch bracket through the shaft bracket, one end of the hatch bracket is equipped with a hatch cover, the middle of the hatch bracket is equipped with a hatch mounting plate, and the other end of the hatch bracket is movably connected to the balancing device. Advantages: Keep the ground level in the use place, suitable for various places; do not occupy the space above the ground when idle, and do not cause obstacles; all wires and cables can be collected in the ground well, beautiful and safe; adopts the labor-saving principle and anti-fall design, and it is very safe and convenient to open and close when in use; the matching accessories can be freely selected, and the combination is flexible and changeable.

[0005] However, in the prior art, the cover plate and the mounting plate are connected to each other vertically through the bracket. However, due to the limited thickness of the mounting plate itself, the vertical connection between the side extensions will lead to an extremely reduced connection strength, which cannot withstand the installation of high-strength and high-weight mounting plates. In addition, in order to be able to flip the mounting plate smoothly onto the surface of the substrate, the mounting position of the mounting plate needs to be flush with the rotating shaft of the bracket. However, this will make the opening and closing of the cover plate more laborious, and will also cause the torque of the connection between the mounting plate and the bracket to increase. During the flipping process, the torque fluid of the mounting plate will increase sharply, thereby causing damage to the bracket.

[0006] Therefore, it is necessary to be able to make a flipping mechanism that can withstand high loads and high quality and can also be assembled flush on the existing flipping well mechanism, so as to ensure the stability and quality of the overall structure. Utility Model Content
