Description

Technical Field

[0001] The invention relates to a sliding hangar door, belonging to the technical field of hangar doors. Background Art

[0002] Hangar doors are part of a large-span single-story building for aircraft maintenance, and many large warehouse doors also use similar structures. Currently, most hangar doors on the market are sliding hangar doors. The structure of sliding hangar doors is composed of multiple door leaves connected in series, and the door opens by sliding to both sides. The disadvantage is that the door leaves are relatively tall, which makes it inconvenient to open the door when vehicles enter and exit. The door opening and closing speed is relatively slow, and when the temperature and humidity difference between indoor and outdoor is large, it will affect the temperature and humidity in the hangar. It is not suitable for aircraft maintenance, warehousing or production-related fields with high temperature and humidity requirements. Summary of the invention

[0054] The present invention is further described in detail below with reference to the accompanying drawings.

[0055] See also Figure 1 to Figure 11 The present invention relates to a sliding hangar door, which comprises a plurality of door leaves 1, wherein at least one of the door leaves 1 is provided with a door opening 2, and a lifting door 3 without a threshold is provided at the position of the door opening 2;

[0056] Fixed air curtains 4 are vertically arranged on the left and right sides of the door opening 2, and slide rails 5 are vertically arranged inside the fixed air curtains 4, and the lifting door 3 is arranged between the left and right slide rails 5;

[0057] The fixed air curtain 4 includes an air inlet 41 and an air outlet 42, wherein the air inlet 41 is located on one side of the room, and the air outlet 42 is located on one side of the door opening. In order to ensure that the fixed air curtain only exchanges the indoor air, the air inlet 41 and the air outlet 42 of the fixed air curtain 4 must be located indoors. Furthermore, since the multiple door panels of the garbage truck hangar door need to overlap with each other during the opening process, in order not to change the original door panel structure and increase the door panel thickness, the fixed air curtain 4 needs to be installed in the thickness range of the door opening 2, and the door panels must not be exposed, otherwise, when the door panels overlap, they will collide with the fixed air curtain with the exposed door panels.

[0058] The slide rail 5 is located inside the air outlet 42;

[0059] A lifting door driving mechanism 6 is arranged above the lifting door 3;

[0060] The lifting door driving mechanism 6 comprises a first transmission shaft 61 arranged in the transverse direction, and a gear commutator 62 is provided at the left and right ends of the first transmission shaft 61, and the left and right ends of the first transmission shaft 61 are respectively connected to the input ends of the left and right gear commutators 62 through a coupling 63, and a wire pulley 64 is provided at the output end of the gear commutator 62, and a lifting wire rope 65 is hung on the wire pulley 64, and one end of the lifting wire rope 65 is connected to the lifting door 3, and the other end of the lifting wire rope 65 is provided with a counterweight 66;

[0061] A driving motor 67 is disposed at the middle of the first transmission shaft 61, and the first transmission shaft 61 is driven by the driving motor 67;

[0062] A buffer pad 68 is provided below the counterweight 66. The buffer pad 68 can buffer the counterweight on one hand, and can also limit the lifting height of the lifting door on the other hand;

[0063] A horizontal air curtain 7 is arranged on the top of the door opening 2 in the transverse direction;

[0064] Since fixed air curtains are arranged on both sides of the lifting door, due to the limitation of the fixed air curtain structure, its air outlet can only be arranged on the outer side of the sliding rail. In order to ensure the sealing of the lifting door, if the door edge is extended to the lifting door position, the fixed air curtain air outlet will be blocked. In order to ensure the normal operation of the fixed air curtain, the door edge can only be extended to the fixed air curtain air outlet position. At this time, there is still a distance between the lifting door and the door edge. In order to ensure the sealing of the lifting door when it is closed and to allow the upper door leaf structure to be opened when the lifting door is lifted, a lifting door transverse movement mechanism 8 is arranged on the lifting door 3; when the lifting door is opened, the lifting door is transversely moved inwardly for a distance through the lifting transverse movement mechanism, so that the lifting door can make way for the upper door leaf frame (which must be set to ensure the strength of the door leaf), ensuring that the lifting door is lifted smoothly, and since the door edge only extends to the fixed air curtain, the fixed air curtain can also work normally at this time; when the lifting door is closed, the lifting door is transversely moved outwardly for a distance through the lifting door transverse movement mechanism, so that the lifting door and the door edge are tightly attached to ensure the sealing of the lifting door when it is closed;

[0065] The lifting door transverse movement mechanism 8 includes a second transmission shaft 81 arranged in the transverse direction, and a driving sprocket shaft 82 is provided at the left and right ends of the second transmission shaft 81. The left and right driving sprocket shafts 82 are respectively arranged on the left and right sides of the lifting door 3. A plurality of driven sprocket shafts 83 are also arranged on the left and right sides of the lifting door 3 from top to bottom. A driving sprocket 84 is arranged on the driving sprocket shaft 82, and a driven sprocket 85 is arranged on the driven sprocket shaft 83. The driving sprocket shaft 82 and its adjacent driven sprocket shaft 83 and the two adjacent driven sprocket shafts 83 are connected by a transmission chain. The outer ends of the driving sprocket shaft 82 and the driven sprocket shaft 83 are both provided with a swing rod 86, and the end of the swing rod 86 is provided with a pulley 87, and the pulley 87 is arranged in the slide rail 5;

[0066] A transverse motor 88 is disposed above or below the second transmission shaft 81 , and an output end of the transverse motor 88 is connected to the second transmission shaft 81 via a sprocket mechanism 89 .

[0067] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
