[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to an inclination angle detecting device for a boarding bridge used in airport equipment.

[0002]

[Prior Art]

 The boarding bridge connecting the airport building and the aircraft entrance / exit is pivotally supported at the base end on the side of the airport building, and the expansion / contraction movement and tilting movement of the tunnel that adapts the entry / exit junction room to the aircraft entrance / exit are: It was operated by an operator who handled the operation panel installed inside the boarding / unloading room.

Regarding the inclination angle of the tunnel, the limit of elevation and the limit of depression are detected by a limit switch arranged in the tunnel.

[0004]

[Problems to be solved by the device]

 However, the inclination angle can be detected only at two positions, the elevation angle limit and the depression angle limit.Because the angle change during the tilting motion cannot be detected, the deceleration or stop procedure of the tilting motion is delayed and the boarding bridge is delayed. It takes time to connect the connection.

[0007] Furthermore, the limit switch has different operating positions when it is turned on and off when the boarding bridge is tilted. Therefore, when changing the position of the tilt angle limit, there is a problem that the adjustment is extremely difficult. .

In view of such conventional circumstances, the present invention makes it possible for the operator to easily grasp the change in the inclination angle of the boarding bridge by adopting a structure in which the inclination angle can be detected steplessly. It is an object of the present invention to provide an inclination angle detecting device for a boarding bridge.

[0007]

[Means for Solving the Problems] In the inclination angle detecting device for a boarding bridge according to the present invention, an expandable / contractible tunnel is tilted with respect to an airport-side joining room by a fulcrum shaft provided at the base end of the tunnel. A detection device for detecting the inclination angle of the tunnel and making a continuous display of it in a boarding bridge that is connected as much as possible and the joining room of the entrance side is connected to the tip of this tunnel. And a rotation angle continuous detection signal output from the rotation angle detection means, which detects the rotation angle of the fulcrum shaft and outputs a rotation angle continuous detection signal. On the basis of this, a central processing means for outputting a tilt motion change signal, and a display capable of displaying a change in the tilt angle of the tunnel based on the tilt motion change signal output from the central processing means. Is.

[0008]

[Action]

 The tilt angle of the tunnel is taken out as a rotation angle continuous detection signal of the fulcrum shaft of the tunnel by the rotation angle detection means, and this rotation angle continuous detection signal is processed into a tilt movement change signal by the central processing means to perform this tilt movement. The change signal is output to the display.

The display continuously displays changes in the inclination angle of the tunnel based on the inclination movement change signal.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

The tilt angle detection device 1 shown in FIG. 1 is provided in a boarding bridge 21 (see FIG. 2) installed in an airport or the like.

The boarding bridge 21 is configured such that a tunnel 22 is expandable / contractible by a stationary passage body 22a and a movable passage body 22b. The tunnel 22 has an ear-like shape on both sides of a base end portion of the stationary passage body 22a. The fulcrum shafts 23 provided in the above are pivotally supported by bearings 24a provided in the airport-side joining chamber 24, respectively, so that they are tiltably connected.

On the other hand, at the tip of the tunnel 22, a boarding-side joining room 25, which can be connected to a boarding / alighting gate of an aircraft (not shown), is connected. An operation panel (not shown) is arranged.

A column 26 is connected to an intermediate portion of the movable passage body 22b to drive the movable passage body 22b up and down, and to extend and retract the tunnel 22 and rotate. Reference numeral 27 is a column that rotatably supports the airport-side joining chamber 24.

In order to connect the boarding / alighting side joining room 25 to the boarding / alighting gate of the aircraft, when the movable side passage body 22b is lifted by ascending drive of the column 26, the tunnel 22 tilts about the fulcrum shaft 23, This tilt angle can be detected and displayed by the tilt angle detection device 1 of the present invention.

That is, the tilt angle detecting device 1 is mainly composed of the rotation angle detecting means 2, the central processing means 3 and the display 4 in FIG.

The rotation angle detecting means 2 is adapted to take out the inclination angle of the tunnel 22 shown in FIG. 2 by the rotation angle of one of the fulcrum shafts 23 pivotally supporting the base end portion of the tunnel 22. Therefore, as shown in FIG. 1, the extension shaft 5 protruding from the fulcrum shaft 23 to the outside of the airport side bonding chamber 24 with the same axis as the fulcrum shaft 23 and the outside of the extension shaft 5 are provided. It is composed of a detector 7 fixed to the airport-side joint chamber 24 via a bracket 6 so as to be positioned, and a coupling 9 for connecting the input shaft 8 of the detector 7 and the extension shaft 5 to each other. ing. Reference numerals 10, 11, and 12 are set screws.

The extension shaft 5 is provided by selecting any one of a screw-in structure, a welding structure and a cut-out structure.

The bracket 6 is formed in a Z-shaped cross section, and a through hole 13 is provided on the mounting side of the detector 7.

The detector 7 is for detecting the turning angle of the fulcrum shaft 23, and is adapted to output a turning angle continuous detection signal A by applying, for example, a rotary encoder or a potentiometer.

The central processing means 3 is for processing the rotation angle continuous detection signal A into a tilt movement change signal B, and a CPU using a computer is applied. The tilt angle limit can be easily set by applying software (a sequencer program).

The display 4 is provided on the operation panel described above, and the tilt of the tunnel 22 is tilted based on the tilt motion change signal B output from the central processing means 3 by applying, for example, CRT, plasma, LCD or the like. The angle can be displayed in graduated increments of 1 °.

Next, the operation of the above embodiment will be described.

When the movable passage body 22 b rises due to the upward drive of the column 26, the tunnel 22 tilts around the fulcrum shaft 23.

The tilt angle of the tunnel 22 that accompanies this tilting operation is extracted as the rotation angle continuous detection signal A by the rotation angle detecting means 2. The continuous rotation angle detection signal A is processed by the central processing means 3 into a tilt motion change signal B, and the tilt motion change signal B is output to the display 4.

Based on the tilt motion change signal B, the display 4 continuously displays the change in the tilt angle of the tunnel 22 at a graduation rate of 1 °. Therefore, an operator who handles the operation panel tilts the tunnel 22. It is possible to grasp changes in motion promptly and reliably.

[Effect of the device]

 The device for detecting the inclination angle of the boarding bridge of the present invention is provided in the vicinity of the fulcrum shaft at the base end of the tunnel, and detects the rotation angle of the fulcrum shaft and outputs the rotation angle continuous detection signal. Based on the detecting means and the central processing means that outputs the tilting motion change signal based on the turning angle continuous detection signal output from the turning angle detection means, and based on the tilting motion change signal output from the central processing means Since the indicator is configured to be able to display the change in the tilt angle of the tunnel, the operator can quickly grasp the change in the tilt angle of the tunnel and perform timely deceleration measures for the tilting operation of the tunnel. And stop measures will be taken, so the wasteful time for connecting the bridge will be eliminated.

Further, since the tilt angle limit can be easily set by a sequencer program, there is an excellent advantage that workability is remarkably improved.
