Description

Technical Field

[0001] The utility model relates to the technical field of hangar equipment, and particularly relates to a large hangar door and its transmission mechanism. Background Art

[0002] The hangar door is an indispensable building in the aircraft maintenance area and is also the first threshold for protecting the aircraft. The hangar door is usually composed of two huge door bodies, and its opening method is generally left - right translation. After being fully opened, the door leaves will be pushed to one side of the hangar opening, thus occupying the space on both sides outside the hangar, which will affect the layout and use of the hangars side - by - side; Reducing the size of the hangar door can partially solve this problem, but this method also reduces the size of the hangar opening, affecting the applicability and the entry / exit efficiency of the hangar. A new type of hangar door is needed to solve the above problems. Content of the Utility Model

[0003] To solve the above problems, the utility model proposes a large hangar door and its transmission mechanism, including folding tracks. The folding tracks are correspondingly arranged above and below at the opening of the hangar. The two folding tracks are respectively slidably connected to the upper and lower sliding disks on the door leaf. The surface of the sliding disk can be attached to the surfaces of the horizontal conveyor belt and the vertical conveyor belt. The horizontal and vertical conveyor belts are respectively arranged along the horizontal and vertical channels of the folding track. A pushing cylinder facing the horizontal channel is provided on the side wall of the hangar. When the door leaf is completely located within the horizontal channel, it can cover the opening of the hangar.

[0004] Furthermore, the door leaf includes a shaft rod. The shaft rod is respectively connected to the centers of the upper and lower sliding disks. Wings are connected to both sides of the shaft rod. The wings are parallel to the hangar opening. Partition plates are connected to the sides of the wings. When the door leaf is located at the intersection of the horizontal and vertical channels, the partition plate contacts the retracted output end of the pushing cylinder.

[0005] Furthermore, the lower folding track and its corresponding horizontal and vertical conveyor belts are located within a folding chamber. The folding track is installed on the side wall of the folding chamber, and the horizontal and vertical conveyor belts are installed on the bottom surface of the folding chamber. The folding chamber is opened below the ground of the hangar. The top of the folding chamber is connected to the hangar ground through a chute, and the chute is slidably connected to the door leaf.

[0006] Furthermore, the upper folding track is installed on the inner side wall above the hangar, and the corresponding horizontal and vertical conveyor belts of the upper folding track are installed on the inner top surface of the hangar. A sealing plate is provided above the hangar opening, and the folding track is flush with the bottom surface of the sealing plate.

[0007] Furthermore, the hangar door is a double - leaf door, and two sets of components are symmetrically distributed at the opening of the hangar.

[0008] The beneficial effects of the utility model are as follows: the utility model controls the movement of the door leaf in the folding track through the cooperation of the horizontal and vertical conveyor belts and the pushing cylinder, thereby realizing the automatic opening and closing of the warehouse door. When the warehouse door is closed, the door leaves are all located in the horizontal channel to close the opening. When the warehouse door is opened, the door leaves are all located in the vertical channels on both sides, and will not occupy the external space. The interval distance between side-by-side hangars can be shortened, which is convenient for the independent use of the hangar. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model is further described below in conjunction with the accompanying drawings:

[0017] As shown Figures 1 to 4 in the figure, a large hangar door and its transmission mechanism include a folding track 1. The upper and lower folding tracks 1 are correspondingly arranged at the opening of the hangar 2. The two folding tracks 1 are respectively slidably connected to the upper and lower sliding disks 301 of the door leaf 3. The centers of the two sliding disks 301 are connected to the erected shaft rod 302. The two sides of the shaft rod 302 are connected to the wing plates 303. The wing plates 303 are parallel to the opening of the hangar 2. The side edges of the wing plates 303 are connected to the partition plates 304. The disk surfaces of the sliding disks 301 can be attached to the belt surfaces of the horizontal conveyor belt 4 and the vertical conveyor belt 5. The horizontal and vertical conveyor belts are respectively arranged along the horizontal and vertical channels of the folding track 1. Among them, the vertical conveyor belt 5 extends to the intersection of the horizontal and vertical channels.

[0018] In this embodiment, the upper folding track 1 is installed on the inner side wall above the hangar 2. The corresponding horizontal and vertical conveyor belts of the upper folding track 1 are installed on the inner top surface of the hangar 2. There is a sealing plate 203 above the opening of the hangar 2. The folding track 1 is flush with the bottom surface of the sealing plate 203. The lower folding track 1 and its corresponding horizontal and vertical conveyor belts are located in the folding chamber 201. The folding track 1 is installed on the side wall of the folding chamber 201. The horizontal and vertical conveyor belts are installed on the bottom surface of the folding chamber 201. The folding chamber 201 is opened below the ground of the hangar 2. The top of the folding chamber 201 is connected to the ground of the hangar 2 through a sliding groove 202. The sliding groove 202 is slidably connected to the shaft rod 302.

[0019] In this embodiment, a pushing cylinder 6 is provided on the side wall of the hangar 2 facing the horizontal road. When the door leaf 3 is located at the intersection of the horizontal and vertical roads, the partition plate 304 contacts the output end of the retracted pushing cylinder 6. Starting the pushing cylinder 6 can push the door leaf 3 from the intersection to contact the horizontal conveyor belt 4. The horizontal conveyor belt 4 can convey the door leaf 3 to the horizontal road one by one. When all the door leafs 3 are located in the horizontal road, they can cover half of the opening of the hangar 2. The other half of the opening is closed by another set of mirror - established components. The two sets of components form the double - leaf doors of the hangar.

[0020] The working principle of the present utility model is as follows:

[0021] When all the door leafs 3 of the two sets of components are located in the horizontal roads of the folding track 1, the opening of the hangar 2 is in a closed state. At this time, starting the pushing cylinder 6 can press each door leaf 3 tightly, achieving the effect of locking the door. When it is necessary to open the hangar 2, retract the output end of the pushing cylinder 6, start the vertical conveyor belt 5, so that the door leaf 3 at the intersection of the horizontal and vertical roads is conveyed into the vertical road. At the same time, start the horizontal conveyor belt 4, so that the door leafs 3 located in the horizontal road are continuously supplemented to the intersection until all the door leafs 3 are transferred into the vertical road. When it is necessary to close the hangar 2 again, reverse the rotation of the horizontal and vertical conveyor belts. The vertical conveyor belt 5 conveys the door leaf 3 to the intersection, and through the pushing cylinder 6, the door leaf 3 at the intersection is pushed under the horizontal conveyor belt 4 and then conveyed into the horizontal road until all the door leafs 3 return to the horizontal road again.

[0022] The utility model controls the movement of the door leaf 3 in the folding track 1 through the cooperation of the horizontal and vertical conveyor belts and the pushing cylinder 6, so as to realize the automatic opening and closing of the warehouse door. When the warehouse door is opened, the door leaf 3 is entirely located in the vertical channels on both sides, without occupying external space, and can reduce the interval distance between the side-by-side hangars 2, facilitating the independent use of the hangars 2.

[0023] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the claimed utility model.
