Apparently, the described embodiments are some but not all of the embodiments of the present utility model. The elements and features described in one embodiment of the present utility model can be combined with those shown in one or more other embodiments. It should be noted that, for the sake of clarity, the representation and description of components and processes that are irrelevant to the present utility model and known to those of ordinary skill in the art are omitted. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0022] The following further describes the present utility model with reference to the accompanying drawings: A push-pull folding hangar door, the structure of the large door ensures good anti-corrosion performance, and all structural components are treated against corrosion to adapt to various working environments in the hangar hall. The hangar door includes two groups of door leaves 1, and the two groups of door leaves are opened and closed in a left-right folding form. The two groups of door leaves 1 are placed between the upper guide rail 2 and the lower guide rail 3. The top of the door leaf 1 moves in the upper guide rail 2 through the upper guide wheel 8, and all the upper guide wheels 8 have the function of preventing tipping and derailment, and have multiple insurance functions. Its bottom moves in the lower guide rail 3 through the lower traveling wheel 7. The two sides of the lower guide rail 3 are provided with slope protection angle steels 5, and the lower guide rail 3 is provided with a drainage system, which is connected to the main building drainage system.

[0023] Each group of door leaves 1 is composed of an odd number of independent door bodies. The independent door body includes an active fan 1-1, and the rest are passive fans 1-2. A passage small door 1-3 is provided on one group of door leaves 1 and opens outwards. A hidden high-sensitivity switch is arranged on the door frame side of the passage small door 1-3. When the passage small door 1-3 is opened, the independent door body does not respond to any operation instructions.

[0024] A drive system 4 is provided below the active fan 1-1. The drive system 4 is controlled by an electrical control system. Through a perfect control program, the control system is triggered, so as to realize actions such as orderly opening and closing of the door body, which is convenient for operation and maintenance. Since a high-performance single-chip microcomputer module is selected as the main control element, the disadvantages of unstable control and frequent maintenance brought by the relay circuit board are avoided.

[0025] The driving system is a self-compensating drum transmission device, equipped with a German brand reduction motor, which drives the active drum to operate through a chain drive or a gear drive device, and has the advantages of beautiful appearance, reliable operation, no slipping, small space occupation, low energy consumption, and smooth opening and closing. The driving system 4 includes a reduction motor 4-1, which drives the drum 4-2, and the drum 4-2 drives the driving wheel 4-4 through a wire rope 4-3. The driving wheel 4-4 is placed in the lower guide rail 3. Among them, the small diameter of the drum 4-2 ensures the compact appearance of the driving fan; the high strength of the drum 4-2 ensures the durability of the mechanism, and the use of a novel multi-strand winding technology ensures the stability of the mechanism operation.

[0026] The door leaf 1 is surrounded by a sealing system, which ensures reliable thermal insulation performance while also preventing light leakage and reducing energy loss. The sealing system uses sealing strips between the door leaf 1 and the wall, in the door leaf 1, and at the bottom of the door leaf 1 to ensure that the hangar door is reliably sealed without blocking the door leaf. The seal design under the door uses EPDM rubber sealing strips to effectively prevent the intrusion of wind and sand. The seal in the door leaf uses EPDM rubber sealing strips with a center seam width of 50 mm, which can effectively prevent accidental pinching of hands. A brush is used on the top of the door leaf 1, which can not only achieve a sealing effect, but also will not cause excessive resistance to the door body.

[0027] Anti-collision buffers 6 are arranged at both ends of the hangar door to prevent the hangar door from running out of the track due to over-position operation, forcibly blocking the hangar door from stopping movement, and effectively ensuring the safe operation of the hangar door.

[0028] The hangar door is also equipped with a safety system, that is, on the two door leaves 1 in the middle of the door opening, a pressure wave safety edge is installed in the closing direction of the door body, and a pressure wave detection unit is installed inside, and an infrared detection unit is installed in the opening direction of the door body. When the door leaf is opened, the safety detection unit detects the 0.5-meter range in the forward direction of the door body. When an abnormal object enters the monitoring range, the door stops running and alarms until the abnormality is resolved. There are sound and light warning lights and operation warning lights on the upper part of each door leaf. The strobe sound and light warning lights run synchronously with the hangar operation, and the alarm volume reaches about 65 decibels 1 meter away from the alarm. When the door body is abnormal and the safety protection function is triggered, the red operation alarm light flashes to remind the operator to pay attention to inspection and safety.

[0029] The utility model adopts a lower load-bearing and upper guiding structure. A load-bearing ground rail is arranged on the ground, and a guiding rail is arranged on the upper part. The power supply safety busbar is arranged on the upper part of the opening, and the transmission motor is arranged on the lower part of the door body. The power supply is supplied to the motor through the cable laid in the door leaf. The motor drives the special reel to rotate, thereby driving the door to turn the corner, so as to realize the opening and closing of the door.
