Abstract

PURPOSE:To aim at the promotion of efficiency for smooth traveling by installing a traveling drive wheel and a support roller or the like separately from a door body, and adjusting a rail radial center with a turning shaft center of the drive wheel at a curve part of a ground guide rail. CONSTITUTION:A traveling function on a ground guide rail 6 and a support function from a section rectangular support rail 9 both are secured by a traveling drive wheel 7 and both horizontal and vertical rollers separately from a door body 3. Therefore, a turning shaft center of the drive wheel 7 is adjusted to a rail radial center of a curve part, thereby dispensing with any travel guide of the door body 3 itself. In this connection, the inside of a horizontal plane is made turnable by a traveling driven wheel 25 in the door body 3 at the outermost end and a support roller or the like. In addition, the door body 3, the drive wheel 7, the support roller or the like are made turnable within the horizontal plane by a connecting pin. Accordingly, such a possibility that the door body 3 might be derailed along a direction of the curve part is prevented from occurring, and thus the travel and its guide are made smoothly performable.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large door for a hangar, and more particularly to a large door for a hangar which has an improved mechanism for opening and closing the large door in front of the hangar of an aircraft.

[0002]

2. Description of the Related Art A conventional opening / closing drive mechanism for a large door in a hangar of an aircraft or the like will be outlined with reference to FIGS. FIG. 9 is a front view of the front of a hangar 1 (building) such as a general aircraft. The hangar large door 2 includes a plurality of (three examples) door bodies 3 that open and close, and a drive for traveling. It has means 4 and support means 5.

The drive means 4 for traveling is for traveling the door body 3 along the guide rail 6 on the ground side, and has drive wheels 7 for traveling and driven wheels 8 for traveling.

The support means 5 supports the door body 3 along a support rail 9 having a rectangular cross section provided on the building side above the ground-side guide rail 6, and is slidable in the vertical direction on the door body 3. And a vertical shaft 10 that can swivel in a horizontal plane, and this vertical shaft 1
0 and a horizontal roller 11 and a vertical roller 12 which run along a support rail 9 having a rectangular cross section.
Have and.

FIG. 10 is a plan view of the front part of the hangar 1. As shown in the drawing, the large hangar doors 2 of the hangar 1 such as an aircraft are lined up along the ground-side guide rails 6 to guide the ground-side guides. The rail 6 is a front straight portion 6A, curved portions 6B on the front left and right portions, and side straight portions 6C on the left and right side portions.

When the door bodies 3 are run horizontally along the front straight portions 6A, the curved portions 6B and the side straight portions 6C and are stored in the door pocket 13, the door bodies 3 are stored horizontally in a row. There are some which try to further reduce the size of the door pocket 13 and promote effective utilization of the site area of the hangar 1. For example, there is the Japanese Utility Model Sho 63-46579, which is also used as a large door for hangars.
-17286, Jitsukai Sho 63-23478 and the like.

However, the door body 3 which is, so to speak, a linear body
When traveling on the ground side guide rail 6, especially on the curved portion 6B, as shown in FIG. 11, if the drive wheels 7 for traveling and the driven wheels 8 for traveling are rotated so that they cannot rotate in a horizontal plane. When it is attached to the body 3, the traveling directions of the drive wheels 7 for traveling and the driven wheels 8 for traveling do not coincide with the traveling directions of the ground side guide rails 6, especially the curved portions 6B. In the case of the drive wheel 7, the angle is shifted by the angle α, and in the driven wheel 8 for traveling, the angle is shifted by the angle β.

Therefore, in an extreme case, there is a problem that the brim portions of the drive wheels 7 for running and the driven wheels 8 for running run up against the ground-side guide rail 6 and derail. In order to prevent this derailment, it is conceivable to widen the above-mentioned collar portion, but it is not possible to obtain stable driving.

In short, when the door body 3 which is a straight body is made to travel on the ground side guide rail 6, especially on the curved portion 6B, as shown in FIG. 12, the driving wheels 7 for running and the driven wheels 8 for running are provided. The rotation axis AX and the center CT of the rail radius R of the curved portion 6B need to match. For this purpose, the drive wheels 7 for traveling and the driven wheels 8 for traveling can be turned in a horizontal plane.

FIG. 13 is a front view of a main part showing this turning structure particularly for the drive wheel 7 for traveling, and FIG. 14 is a plan view of the same part, showing a vertical shaft 14 that can turn in a horizontal plane. After supporting the drive wheels 7 for traveling on the lower portion of the door body 3, the drive motor 16 is rotationally driven around the rotary shaft 17 (rotational axis AX) via the speed reducer 15.

In this way, the traveling drive wheel 7 can turn in a horizontal plane, and even when traveling on the curved portion 6B, the center CT of the rail radius R of the curved portion 6B and the rotation axis AX of the traveling drive wheel 7 are provided. Can be matched with. A guide roller (not shown) may be provided in front of and behind the drive wheel for traveling 7 so as to sandwich the head of the ground-side guide rail 6.

However, as shown in FIG. 14, when the door body 3 travels through the curved portion 6B, the drive motor 16 projects from the side surface (the back surface side in the illustrated example) of the door body 3 (this projected length is D In addition, as shown in FIG. 13, a void is formed in the lower portion of the door body 3 by the height H.

Since the large door 2 for the hangar receives a large wind pressure when it is closed, and the inside of the hangar 1 is required to have a predetermined airtightness, such a drive motor 16 is used for the door body 3.
There is a problem in that the protrusion of the length D from the above and the generation of the void portion of the height H formed in the lower portion of the door body 3 are very obstacles.

However, conventionally, such a curved portion 6B has been used.
There is no simple drive mechanism for traveling when the door 3 travels through the portion, and improvement has been demanded.

[0015]
