Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a non-retractable boarding bridge.

Conventionally, boarding bridges at local airports, etc., connect a non-extendable passageway body rotatably in the horizontal and vertical directions to a circular base chamber installed on pillars erected near the airport building. A non-extendable boarding bridge is installed with a traveling platform that has vertically extendable struts at the bottom near the tip, and connects a circular chamber at the tip with an aircraft connection section at the tip of the passageway, which connects the airport building and parked aircraft. were connected. However, since the passageway body does not expand or contract, if there is an error in the parking position, the aircraft connecting part of the boarding bridge may not reach the aircraft.

The purpose of this invention is to connect a non-extendable passageway so that it can rotate horizontally and vertically to a base circular chamber installed on a support that will be erected near an airport building. In a vehicle in which a traveling bogie with a supporting support is provided, and a circular end chamber having a body connecting portion is connected to the tip of the passage body, a part of the floor of the connecting portion is moved forward along the guide member by an appropriate drive mechanism. To provide a non-extendable boarding bridge which is capable of being extended and articulated even when the aircraft is parked at a position slightly deviated from its normal parking position.

The present invention will be described below based on an embodiment shown in the drawings. Reference numeral 1 denotes a base passage body, whose base end side is connected to an airport building 2, and the other end is connected to a base circular chamber 4 provided on a support column 3. A non-expandable passage body 5 is connected to the base circular chamber 4 so as to be rotatable in the horizontal and vertical directions, and a traveling carriage 7 having a column 6 that is vertically extensible is provided at the lower part near the tip of the passage body 5. ,
A tip circular chamber 9 having a body connecting portion 8 is connected to the tip of the passage body 5.

The tip circular chamber 9 is rotatably supported by an arm 10 fixed to the passage body 5, and one end of both sides is fixed to the tip of the circular chamber, and the other end is connected to a curtain via guide rollers 12a, 12b. reel 1
The slat curtains 3a and 13b are arranged so as to be able to be closed by slat curtains 11a and 11b which can be freely rolled up and drawn out.

Reference numeral 14 denotes a notch formed on the right side of the front floor of the body connecting portion 8, and guide rails 15 are provided on both sides.
a, 15b are provided, and a raised floor 16 formed slightly higher than the floor of the connecting portion 8 is provided in the inner part.

Reference numeral 17 denotes a movable bed, with guide rollers 18 pivoted by shafts 19 at the front and rear of both sides, and serving as support and guidance for the movable bed 17 by engagement with the guide rails 15a and 15b, and at the front and rear of both sides of the lower surface. Later, a guide roller 20 is provided to protrude horizontally using a support member 21, and is guided in the lateral direction by engaging with guide plates 22a and 22b bent at the lower ends of the guide rails 15a and 15b.

Reference numeral 23 denotes a power cylinder fixed to the center of the lower surface of the body connecting part 8, and the tip of the rod that expands and contracts by forward and reverse rotation of a nut installed therein is connected to the lower surface of the movable bed 17, and the movable bed is expanded and contracted by the cylinder 23. 17 is moved back and forth. 24 is a triangular-shaped flexible safety curtain provided between the right side of the movable floor 17 and the middle part of the tip of the right bellows body;
It consists of a spring-filled cloth bag 24a whose both ends are fixed to the right end of the movable bed 17 and the middle part of the right bellows body 8a, and a triangular cloth 24b attached to the inside of the cloth bag 24a, which expands and contracts as the movable bed 17 moves. It is freely available.

Reference numeral 25 denotes a safety shelf that expands and contracts in a double telescopic manner, and includes a first member 25a, a second member 25b ₁ and 2 that are fitted in order.
5b ₂ , and a third member 25c, of which the first member 25a is pivoted horizontally around a vertical axis on the floor of the fuselage connector 8 by a bracket provided on the left outer wall 8b of the fuselage connector 8. When not in use, the second and third members 25b ₁ , 25b ₂ and 25c are stored in a shortened state as shown by the two-dot chain lines in Figures 3 and 4, but when in use they are stored as shown in Figures 3 and 4. It is designed to be able to move to a rotating position in the extended state. 25d _1,2
Reference numerals 5d ₂ , 25e ₁ , and 25e ₂ are locking chains, which are stretched between the first member 25a and the second members 25b ₁ , 25b ₂ and between the second members 25b ₁ , 25b ₂ and the third member 25c, respectively. There is.

Reference numeral 26 designates a lock pin, whose upper bent portion protrudes from an L-shaped hole 27 provided in the first member 25a, and by moving the bent portion up and down, the lower portion of the lock pin 26 is removed from the lower portion of the first member 25a. haunted,
An extendable safety fence 25 can be locked by protruding into a hole 28 provided in the floor of the fuselage connecting portion 8. In FIG. 3, the safety fence 25 is in an intermediate position,
In FIG. 4, the safety fence 25 is shown in the extended position.

When the aircraft P is parked at the correct position, the boarding bridge is operated and connected to the aircraft P (Fig. 10), the safety fence 25 is rotated to the position shown by the solid line in Fig. 3, and the locking pin is locked. Locked by 26. If the aircraft P is parked at a position slightly away from the normal position, operate the boarding bridge to move it to a position close to the aircraft P (11th
(Fig. 12), by extending the cylinder 23 and protruding the movable floor 17, it is connected to the aircraft P (Fig. 12). At this time, the safety curtain 24 is pulled out by the movable floor 17 to form a triangular shape, and closes the area between the aircraft P and the lower right side of the connecting portion 8. On the other hand, if the safety fence 25 is extended and rotated to the position shown by the solid line in FIG. 4 and then locked with the lock pin 26, the space between the aircraft P and the upper left side of the movable floor 17 is closed, allowing passengers to board and exit safely. It is possible.

The driving mechanism for the moving bed 17 is the cylinder 2.
In addition to 3, a chain with both ends fixed to the center of the moving bed is stretched by sprockets placed in front and rear of the moving bed, and one of the sprockets is moved forward or reverse by a deceleration motor fixed to the lower surface of the machine body. It is the same as described above, even if the rear end is extended to an appropriate length and engaged with a rack fixed to the lower surface of the moving floor and a pinion provided at the tip of the deceleration motor fixed to the lower surface of the aircraft connection. It is possible to implement

As described above, the present invention provides a notch in a part of the right side of the floor of the fuselage joint, a movable bed that can be protruded forward by an appropriate drive mechanism in the notch, and a connection between the right side of the movable bed and the right bellows body. A triangular flexible safety fence is provided between the middle part of the tip, and a safety fence is provided that rotates around the vertical axis on the fuselage joint floor on the left side of the movable floor and expands and contracts horizontally. Even if the aircraft is parked a little further away than the normal parking position, it is possible to safely board and alight by connecting the movable floor with a small amount of power.
