[Industrial applications]

 The present invention relates to a large door for an aircraft hangar that minimizes a swiveling space during open storage.

[0002]

[Prior art and its problems]

 In a conventional aircraft hangar, a large sliding door type door is installed at the front door of the building, guided by a guide rail on the upper side and erected on the floor by the lower side. It is provided so that it can be opened and closed. In this type of hangar, it is necessary to form a door pocket with a width of at least a large door on the left and right sides of the doorway provided in the building, which causes the inconvenience that the doorway is pressed, and the building is correspondingly There is no choice but to increase the size. In addition, rails had to be attached to each large door, which was extremely economical.

In order to solve such a problem, an aircraft hangar as disclosed in Japanese Utility Model Laid-Open No. 63-46579 has been proposed. In this aircraft hangar, separate guide rails and rails are assigned to the large doors that are divided into left and right, and each of these guide rails and rails is laid in the frontage direction of the entrance and exit, and The left and right door pockets are connected to each other along the side wall via curved portions, and the radius of curvature of each curved portion extends from the inner curved portion to the outer curved portion. Each of the large doors is made up of a three-piece structure consisting of a small door in the center and a relatively wide middle door rotatably connected to the left and right sides of the small door. The door is provided with an opening / closing drive means. According to the large door structure of the aircraft hangar, the problem of pressing the doorway has not been solved because the door pockets are provided inside both sides of the building. In other words, with a structure in which two wheels are attached to a small door that is narrow and forms a large door, and one wheel is attached to two wide middle doors, the turning radius cannot be minimized, and the hangar can be The effective space cannot be reduced. In addition, the middle door is connected to both sides of the small door, and the connecting portion bears the own weight of the middle door, and the hinge system is still complicated.

An object of the present invention is to provide a large door for an aircraft hangar in which the swivel space of the large door is reasonably minimized and the door is not pressed by the storage of the large door.

[0005]

[Means for Solving the Problems]

 The configuration of the present invention, which solves the problems of the prior art, is such that the upper and lower sides of an aircraft entrance / exit are guided along a guide rail installed on the building, and the lower side is on a rail laid on the floor. In a large door of an aircraft hangar that is opened and closed by a large self-propelled door, a block structure in which wheels running on rails are mounted on the lower two sides of the large door is pivotable. In addition to being supported, either or both wheels have a drive structure.

[0006]

[Action]

 When opening the doorway of the building, when a large door that runs on the rail moves into the curved part of the rail that reaches the door's storage part, the block structure supporting the wheels turns around the large door and the radius of curvature is increased. A large door can be swiveled and stored by a small swiveling action. That is, the turning space of the large door can be minimized.

FIG. 1 is a front view of an aircraft hangar using a large door of the present invention, FIG. 2 is a plan view of a large door structure portion, FIG. 3 is a partially cutaway plan view of a drive wheel portion having a block structure, and FIG. 4 is a drive wheel portion. Is a partially cutaway front view, FIG. 5 is a plan view of a main part showing the swinging operation of the large door, FIG. 6 is a front view of an aircraft hangar using the large door and the small door, and FIG. 7 is the swinging operation of the small door. FIG. 8 is a plan view of the main part, and FIG. 8 is a front view of the main part showing another embodiment of the opening / closing means for the vertical tail passage opening of the aircraft.

Reference numeral 1 denotes a building that constitutes an aircraft hangar, and a front door wall 1a of the building 1 has a wide entrance / exit 2 for an aircraft. The doorway 2 is configured to be opened and closed by a plurality of (eight in the embodiment) large doors 3, and four large doors 3 are housed along the outer side surfaces of the left and right side walls of the building 1. It The upper side of the large door 3 is guided along a guide rail (not shown) installed on the gable wall 1a of the building 1, and the lower side of the large door 3 is self-propelled on a rail 5 laid on the floor surface 4. It is configured to do. As shown in FIG. 1, cutout recesses 6 are provided on both sides of the lower portion of each large door 4, and wheels 7 mounted on the rails 5 are pivotally supported in the cutout recesses 6. A block structure 8 is interposed, and the block structure 8 is provided vertically on the lower surface of the large door 3 along the vertical axis passing through the center point of the wheel 7 and corresponding to the cutout recess 6. It is pivotally attached to the posture axis 9. Further, a motor 10 with a speed reducer is attached to one side of the block structure 8 so as to drive the wheels 7 via a transmission mechanism 11 such as a gear. In order to balance the left and right sides, as shown in FIG. 5, the directions of the motors 10 attached to the left and right block structures 8 are opposite to each other. Further, in this embodiment, two wheels 7 having a drive structure are provided for the large door 3, but either one may have a driven wheel structure.

The rail 5 has a single-line structure, and the rail 5 is laid inside a pit 12 provided on the floor surface 4, and the upper surface of the rail 5 is substantially the same height as the floor surface 4. As is apparent from FIG. 2, a chamfered portion 1b is formed at a front corner of the building 1, and the rail 5 corresponding to the chamfered portion 1b has a curved portion 5a having a small radius of curvature. Is formed, and the rail 5 extends in the depth direction along the outside of the outer wall of the building 1. Guides 13a having ends flared in a trumpet shape are provided on both sides of the floor surface 4 corresponding to the curved portions 5a of the rails 5 and guides the turning motion of the block structure 8. A rail 13 is attached. Then, two side rollers 14 rolling on contact with the inner surfaces of the both guide rails 13 are pivotally supported by the block structure 8, and by the contact action between the both side rollers 14 and both guide rails 13, The large door 3 is adapted to smoothly swivel through the curved portion 5a.

As shown in FIG. 1, an opening 15 through which a vertical stabilizer of an aircraft passes and communicates with an upper part of the entrance / exit 2 is formed in an upper part of a gable wall part 1 a of a building 1, and a vertical slide is performed in the opening 15. It is known that the shutter 16 can be opened and closed. However, since the shutter 16 of this kind has a flexible structure, it has a disadvantage that when it is swung by a strong wind or the like, it not only vibrates greatly and emits noise, but also wind and rain enter the building 1 through the gap caused by the bending. Further, since the shutter 16 has a flexible structure, there is a structural complexity that a guide rail (not shown) of the large door 3 corresponding to the lower side of the opening 15 must be separately provided. Therefore, as shown in FIG. 8, instead of the shutter 16, a plurality of hanging wall plates 17 having rigidity and wall thickness can be moved up and down by a hoisting means such as a winch (not shown), and the opening 15 is opened. Try to open and close. With this structure, the problem of the shutter 16 can be solved, and the upper side guide means of the large door 3 can also be carried by the hanging wall plate 17 at the lowermost stage. The lower end of the upper hanging wall plate 17 is located in front of the upper part of the lower hanging wall plate 17 to prevent rainwater from entering.

As shown in FIG. 6, a door that opens and closes the entrance / exit 2 of the building 1 by two large doors 3 whose upper sides partially correspond to the openings 15 and a door body 18 in which a large number of small doors 18 a are connected. The structure. Since the large door 3 has the same structure as that described above, detailed description thereof will be omitted. Further, one wheel 19 running on the rail 5 is provided at the center of the lower side of each small door 18a to minimize the turning space as shown in FIG. Then, for example, one wheel for every three small doors 18a is used as a drive wheel, and the door body 18 can be self-propelled. In this way, by combining the door body 18 in which a large number of small doors 18a are connected with the large door 3, at least the small doors 18a can be manufactured in a factory, and the small doors 18a are brought into the field and assembled to form the door body 18. Since it can be configured, only the on-site assembly work of two large doors 3 is sufficient, so that the number of on-site work days can be significantly reduced. In the figure, 20 is a sealing material having a bellows structure.

[0012]

[Operation] As shown in FIG. 5, when the wheel 7 intervenes in the curved portion 5a of the rail 5, the wheel 7 moves along the cutting line of the curved portion 5a, but the large door 3 has a block structure. It pivots with respect to the body 8 via an axis 9. At this time, the block structure 8 advances while projecting outward from the plate surface of the large door 3. The swing locus of the large door 3 when opening or closing the doorway 2 is exactly the same.

[0013]

[Effect of device]

 As described above, according to the configuration of the present invention, the following effects can be obtained. At the bottom of the self-propelled large door, two block structures that pivotally support the wheels traveling on the rails are individually arranged so as to be able to turn, and either one or both wheels are installed. Since it has a drive structure, the swivel space of the large door can be reasonably minimized, and the curved part with a small radius of curvature allows the large door to swivel and house along the outside of the building in a small circle. It is possible to reduce the amount of space required for opening the door and to shorten the time required to open and close the aircraft doors using the large door.
