Each of the pressure reducing valves 21 is provided with an exhaust port.
The exhaust port does not operate when the first cylinder 14 and the second cylinder 16 extend, but operates when the first cylinder 14 and the second cylinder 16 contract to release air pressure to the atmosphere.

 The refueling nozzle operating device B is configured as described above.

 The above is the description of the configuration and the like.

 The operation and the like will be described below.

At the time of refueling, the servicer 1 is stopped near the refueling port a of the aircraft A, the stored intake hose 7 is lowered to the ground, and the joint at the tip thereof is connected to the discharge part 5 of the highland refueling device 6 and the refueling worktable is connected. 4 is raised to connect the fueling nozzle N at the tip of the fueling hose 8 to the fueling port a of the aircraft A (see also FIG. 4 and FIG. 3).

The fuel taken in from the discharge unit 5 of the highland refueling device 6 on the ground is taken in via the intake hose 7, the various refueling equipments 2, the refueling hose 8, the refueling nozzle N, the refueling port a, etc. Refueled. When the refueling of all the tanks is completed, the connection between the tip of the intake hose 7 and the discharge portion 5 of the highland refueling device 6 is disconnected, and the connection between the refueling nozzle N and the refueling port a of the aircraft A is also released. After retracting the refueling workbench 4 while storing the refueling hose 7 and the refueling hose 8, the servicer 1 leaves the aircraft A.

Incidentally, this servicer 1 is provided with the following refueling nozzle operating device B (see FIG. 1). That is, the refueling nozzle operating device B includes a vertical support shaft 13 that is rotatable left and right and expandable and contractable up and down, a horizontal support shaft 15 that can expand and contract back and forth, and the weight of the refueling hose 8 and the like attached thereto. In consideration of the above, the first cylinder 14 and the second cylinder 16 (see also FIG. 2), each of which is set to an air pressure which can be manually extended and retracted, are arranged on the refueling worktable 4 in a predetermined positional relationship.

The first cylinder 14 and the second cylinder 16 function as auxiliary and balancers based on the air pressure controlled as described above, so that the operator can move the vertical support shaft 13 and the The refueling nozzle N can be manually operated with a small force via the horizontal support shaft 15. That is, although the refueling nozzle N is very heavy due to the weight of the connected refueling hose 8 and the like, the refueling nozzle operating device B
Is held by its nozzle holder 17 via a vertical support shaft 13, a first cylinder 14, a horizontal support shaft 15, a second cylinder 16, etc., so that it can be freely and easily operated up and down, front and rear, left and right, etc. . In this manner, the worker places the refueling nozzle N on the refueling port a of the aircraft A from the stored state (first
(See the solid line in the figure.)
3. By extending the first cylinder 14, the horizontal support shaft 15, the second cylinder 16, and the like, the positioning and connection can be easily performed (see the imaginary line in FIG. 1 and FIG. 4).

The refueling nozzle operating device B maintains the state in which the refueling nozzle N is aligned with the refueling port a during refueling. Then, when the refueling is completed and the connection between the refueling nozzle N and the refueling port a is released, the worker can easily return the refueling nozzle N to the original storage state (see the solid line in FIG. 1). That is, the vertical support shaft 13, the first cylinder 14, the horizontal support shaft 15, the second cylinder 16 and the like are easily shortened following the refueling nozzle N.

In addition, by adjusting the set air pressure, even if the worker forgets to return to the retracted state after disconnecting the refueling nozzle N, the refueling nozzle N is gradually turned on for a predetermined time. Can be set to automatically return to the original storage state. That is, by setting the air pressure in this way, the first cylinder 14 and the second cylinder 16 are gradually shortened due to their own weight and the like, and the air pressure is gradually released from the exhaust port of the pressure reducing valve 21 to the atmosphere, so that the vertical support is achieved. The shaft 13 and the horizontal support shaft 15 are similarly shortened. Thus, the refueling nozzle N gradually returns to the original storage state. Therefore, when the air pressure is set in this manner, there is no possibility that an accident such as a collision of the refueling nozzle operating device B with the aircraft A will occur even if the refueling nozzle N has forgotten to return to the retracted state.

Further, in the refueling nozzle operating device B of the illustrated embodiment, a nozzle holder 17 is attached to the tip of the horizontal support shaft 15 via a ball joint 18 so as to be swingable (indicated by imaginary lines in FIG. 1). reference). Therefore, the refueling nozzle N
There is an advantage that it is possible to cope with any angle such as a case where it is a little bit, and it is possible to extremely easily align the position with respect to the filler port a.

 The above is the description of the operation and the like.

[Effects of the Invention] As described above, the servicer refueling nozzle operating device according to the present invention is configured by arranging a predetermined vertical support shaft, a horizontal support shaft, a first cylinder, a second cylinder, and the like on a refueling workbench. Has the following effects.

That is, the refueling nozzle held by the nozzle holder can be freely and lightly operated without difficulty in up, down, front, back, left, and right directions. Therefore, when refueling the aircraft, the worker can raise the refueling nozzle with a small force and connect it to the refueling port of the aircraft on the refueling work bench, etc.
The work is simplified and the operability is significantly improved.

As described above, the effects exhibited by the present invention are remarkable and large, for example, the problems existing in this type of conventional example are eliminated.
