Description

Technical Field

[0001] This utility model belongs to the field of hangar door technology, specifically a wind-resistant hangar door. Background Technology

[0002] In aviation ground facilities, hangar doors, as large opening devices, must simultaneously meet the core requirements of large opening size, convenient operation, and environmental adaptability, especially wind resistance. Currently, multi-panel folding doors are widely used in hangar scenarios due to their flexible opening methods and small space occupation. However, the joints of their folding structures suffer from insufficient rigidity. In strong wind environments, they are prone to deformation and swaying due to wind pressure loads, which can even lead to sealing failure or structural damage. Traditional designs that rely solely on the wind resistance of the door frame itself are no longer sufficient to meet the requirements of high-wind-speed areas.

[0003] To improve the wind resistance of multi-panel folding doors, existing technologies mainly optimize the door body by thickening the door material and strengthening the hinges. However, these methods increase the weight of the door body, affect the flexibility of opening and closing, and have limited effect on improving the overall wind pressure deformation resistance. Therefore, we propose a wind-resistant hangar door. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 A wind-resistant hangar door includes an electrically operated multi-panel folding door 1. A first gantry frame 11 is fixedly installed on the rear side of the door frame of the electrically operated multi-panel folding door 1. A second gantry frame 12 is fixedly installed on the top of the first gantry frame 11. A crossbeam 14 is slidably installed inside the first gantry frame 11. Abutments 15 are evenly fixedly installed on the front side of the crossbeam 14. Two sets of electric hoists 13 are evenly fixedly installed on the top of the second gantry frame 12. The two sets of electric hoists 13 are synchronously controlled by the same servo synchronous controller. The lifting cables of the electric hoists 13 are connected to the top of the crossbeam 14. The bottom left and right sides of the crossbeam 14 are fixedly equipped with... A set of guide columns 17 are connected to the first gantry frame 11 by high-strength bolts 16. A set of first sliding grooves is provided on both the left and right sides of the inner wall of the first gantry frame 11, penetrating to the bottom of the first gantry frame 11. A second sliding groove is provided on the top of the first gantry frame 11, communicating with the two sets of first sliding grooves. A storage slot is evenly provided between the electric multi-panel folding door 1 and the first gantry frame 11, communicating with the second sliding groove. Two sets of through holes are evenly provided on the top of the second gantry frame 12. A crossbeam 14 is slidably disposed within the first and second sliding grooves. The guide columns 17 slide... The abutment 15 is slidably positioned in the storage slot, and the hoist 13's sling is connected to the crossbeam 14 through the through hole. The electric hoist 13 suspends and stores the crossbeam 14 into the first and second slides of the first gantry frame 11. The crossbeam 14 then drives the abutment 15 to be stored in the storage slot between the first gantry frame 11 and the electric multi-panel folding door 1. Simultaneously, the guide post 17 is stored in the first slide of the first gantry frame 11, thus ensuring that multiple door panels of the electric multi-panel folding door 1 can be unfolded and folded. The front side of the abutment 15 corresponds to the rear side of the door panel of the electric multi-panel folding door 1. The rear side of the first slide groove is provided with a first insertion hole and a second insertion hole. The first insertion hole is located above the second insertion hole. The rear side of the guide post 17 is provided with a threaded hole. The high-strength bolt 16 passes through the first insertion hole and is screwed into the threaded hole. The high-strength bolt 16 passes through the first insertion hole of the first gantry frame 11 and is screwed into the threaded hole of the guide post 17, thereby fixing the guide post 17 in the first slide groove of the first gantry frame 11. In turn, the crossbeam 14 at the top of the guide post 17 is fixed in the first gantry frame 11, thereby preventing the crossbeam 14 from suddenly falling due to the failure of the electric hoist 13. The high-strength bolt 16 corresponds to the second insertion hole.

[0022] Working principle: The electric hoist 13 suspends and stores the crossbeam 14 into the first and second slide grooves of the first gantry frame 11. The crossbeam 14 drives the abutment 15 to be stored in the storage groove between the first gantry frame 11 and the electric multi-panel folding door 1. At the same time, the guide column 17 is stored in the first slide groove of the first gantry frame 11, so as to ensure that the multiple door panels of the electric multi-panel folding door 1 can be unfolded and folded. The high-strength bolt 16 is threaded through the first insertion hole of the first gantry frame 11 and screwed into the threaded hole of the guide column 17, so as to fix the guide column 17 in the first slide groove of the first gantry frame 11. In addition, the crossbeam 14 at the top of the guide column 17 is fixed in the first gantry frame 11, so as to prevent the crossbeam 14 from suddenly falling due to the failure of the electric hoist 13.

[0023] When the electric multi-panel folding door 1 is subjected to wind resistance, the high-strength bolt 16 is unscrewed, and the electric hoist 13 drives the crossbeam 14 to move downward. At this time, the front side of the abutment block 15 will fit against the rear side of the door panel of the electric multi-panel folding door 1, thus abutting the rear side of the door panel of the electric multi-panel folding door 1 through the abutment block 15, and cooperating with the crossbeam 14 and the first gantry frame 11 to support the rear side of the door panel of the electric multi-panel folding door 1, thereby improving the strength of the door panel of the electric multi-panel folding door 1 and thus improving the wind resistance of the electric multi-panel folding door 1. When the crossbeam 14 moves downward, it drives the guide column 17 to move downward. When the bottom of the guide column 17 is flush with the bottom of the first gantry frame 11, the threaded hole on the guide column 17 will align with the second insertion hole on the first gantry frame 11. At this time, the high-strength bolt 16 is screwed through the second insertion hole and threaded hole to fix the position of the guide column 17. Then, the crossbeam 14 makes the abutment block 15 stably abut against the rear side of the door panel of the electric multi-panel folding door 1.
