Description

Technical Field

[0001] The present invention relates to the technical field of push-pull hangar doors, in particular to a push-pull hangar door and a door installation and construction method. Background Art

[0002] In the aviation field, hangars are key facilities for parking, maintenance and overhauling aircraft. The design and performance of their doors are of vital importance. Hangar doors are not only passages for aircraft to enter and exit the hangar, but also serve as part of the external protective structure. They need to have good windproof, soundproof, and heat-insulating properties to protect the internal environment of the hangar and ensure the safe storage and maintenance operations of aircraft. For example, the announcement number CN105484603B discloses a hangar door with all-round image monitoring. A hangar door centralized control box is installed on one side of the hangar door opening, and a door control box is installed inside each door leaf. A limit switch is installed on the bottom crossbeam of the hangar door, and a metal sensor plate is installed on one side of the hangar door ground rail. The signal output end of the limit switch is connected to the signal input end of the hangar door centralized control box. Several panoramic cameras are installed on all sides of the hangar door, and a video processing controller is installed inside each door leaf. The output end of each panoramic camera is connected to the input end of its own video processing controller, and the output end of the video processing controller is connected to a display screen, forming an all-round image monitoring system. The invention can fully monitor the hangar area, centrally control the doors of the hangar door, complete the door opening or closing operation, and achieve precise operation by limiting the hangar. If an obstacle such as a pedestrian or vehicle is detected during the operation of the door, the door will immediately slow down and stop;

[0003] The existing hangar sliding doors can meet the needs of use, but they are mainly supported by bottom slide rails or top guide devices. There is a certain gap between the door leaf, the door frame and the ground. When strong winds blow, strong airflow can easily flow in from the gap, forming an air pressure difference between the inside and outside, resulting in uneven force on the door leaf, which may cause shaking, deviation or even derailment, affecting the stability of the door structure. Secondly, when vehicles or personnel enter the hangar, the hangar sliding door needs to be completely closed before entering, which is inefficient and extremely time-consuming. Summary of the Invention

The worm gear 5526 rotates to engage the worm wheel 5525 to rotate. The rotation of the worm wheel 5525 drives the fixed second wire drum 5523 to rotate. The rotation of the second wire drum 5523 drives the second wire rod 5524 inside to descend. The descent of the second wire rod 5524 drives the connecting plate 5519 connected at the top and the two sets of sliders 5518 to descend in the slide rail 5510. The descent of the two sets of sliders 5518 drives the fixed shaft 5517 and the second gear 5516 installed in the center to descend. After descending, it is only necessary to move the baffle 5514 on one side to rotate upward. The baffle 5514 rotates upward to drive the driving shaft 5513 in the center to rotate. The driving shaft 5513 rotates to drive the first gear 5515 in the center to rotate. The first gear 5515 rotates to engage the rack plate 472 on one side to disengage. Then, the splicing door panel 5 that has disengaged from the rack plate 472 is pushed to open. When it needs to be closed, after re-docking, the push rod 5529 is rotated in the opposite direction to complete the reset.
