Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hanging type refueling device in which a refueling hose is movable in the horizontal direction, and particularly to wiring of a signal line from a hand switch provided on the refueling hose.

Hanging-type refueling devices, in which a refueling hose with a refueling nozzle connected to the tip is hung from a high place at a refueling station, have recently been designed to expand the refueling range by moving the refueling hose horizontally. It is emerging.

In this type of refueling system, the hanging type of the refueling hose is the same as the conventional one with a fixed type.
In order to appropriately drive the fuel hose lifting device and to reset the flow indicator to zero, it is necessary to connect the hand switch and the refueling hose lifting device etc. with a signal line. However, in the past, a signal line with a large cross-sectional mirror was placed inside the refueling hose, which reduced the effective closing area of the refueling hose and reduced the area for discharging oil, and the signal line was particularly carefully covered. There were various drawbacks, such as the need for a secure seal structure and the extremely troublesome maintenance and inspection of the signal lines.

In order to improve this point, it is possible to arrange the signal line along the outer wall of the refueling hose, but in this case, the signal line should follow the refueling hose whose hanging length changes depending on the elevation. Some kind of countermeasure will be required. In particular, in the case of a horizontally movable type, the length between the refueling hose and a fixed connection point such as a lifting device changes, so special consideration must be given to the arrangement of signal lines during this period. In other words, it goes without saying that the signal line must follow the above-mentioned change in distance due to the horizontal movement of the refueling hose, and since this area is usually covered with a storage case for the lifting device and there is only a very narrow space, the signal line must It is necessary to avoid the wire from coming into contact with the storage case, lifting device, etc. SUMMARY OF THE INVENTION In view of the above circumstances, it is an object of the present invention to provide a fuel supply device that satisfies the above-mentioned various demands when a signal line is arranged along the outer wall of a fuel supply hose.

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

In FIGS. 1 to 3, a storage case 2 is fixed at a high place in the gas station, such as a river ceiling, a beam, or a lid. Inside the storage case 2, a hose reel 4 is rotatably disposed via a bracket 3, and a motor 5 and a reduction gearbox 6 are also installed. It is designed to rotate in the opposite direction. Also, inside the case 2, one end of each is connected to a pin 7.
An arm mechanism is provided that includes a pair of first and second arms 80 that are swingably connected to each other. This arm mechanism is intended to prevent the hanging length of the refueling hose from changing even when the refueling hose (described later) moves horizontally. The other end of the arc-shaped first arm 8 is swingably supported by a pin 11 on a bracket fixed to the case 2, while the rod-shaped second arm The other end of 9 is
It is pivotally supported to the truck 12 by a pin 13 so as to be swingable. This trolley 12 is movable along a pair of rails 14 and 15 that extend linearly in the horizontal direction and are fixed oppositely to each other at the lower part of the side wall of the case 2. A long hole 16 is provided in the bottom wall of the case. A refueling hose 17 is wound around the hose reel 4, and the refueling hose 17 passes through a pair of rollers 18 held by a bracket 10 to a first
It is arranged along the second arms 8 and 9, and then passes through the truck 12 and hangs down from the elongated hole 16 of the case 2.

Such a refueling hose 17 has a refueling/slip 1 at its tip.
9 is connected, and a hand switch 20 is attached to the nozzle 19 at or near the lower end of the refueling hose 17. On the other hand, a pipe 21 extending from the lower muscle oil tank (not shown) is arranged along the high point 1, then extends into the case 2, and is connected to the oil supply hose 7 via a rotary liquid-tight joint (not shown). has been done. Therefore, by driving the oil supply pump (not shown) connected midway through the pipe 21, the oil pumped up from the oil tank is forced to be sent to the oil supply nozzle 19 via the pipe 21 and the oil supply hose 17. In addition, in the figure, 22 is a guide roller provided on the first arm 8, and 23 is a trolley 12.
The guide rollers 22 and 23 ensure smooth feeding and winding of the refueling hose 17. A signal line extends from the hand switch 20 for forward and reverse rotation of the hose reel 4 or for returning the oil supply amount indicator (not shown) to zero. It is generally constructed by connecting three third signal lines 24, 25, and 26 to each other. The first signal line 24 connects the hand switch 20 and the connection terminal 27 provided on the trolley 12, and after being pulled out from the hand switch 20, it is wound around the outer circumference of the refueling hose 17 in the form of a telescopic coil. The guide pipe 28 extends upward and passes through the guide pipe 28 provided on the truck 12 so as to pass through the elongated hole 16 of the case 2, and reaches the connection terminal 27. By providing this guide pipe 28, the first signal line 24 does not directly slide against the pair of dust removal brushes 29 arranged so as to close the elongated hole 16, thereby preventing damage to the first signal line 24. The second signal line connects a connection terminal 27 provided on the trolley 12 and a bracket 101.
The first,
It is arranged along the second arms 8,9.

This second signal line 25 is connected by a holder 31 fixed to the bracket 10 in the vicinity of the pivot point 11 of the first arm 8, and also in the vicinity of both pivot points 7 and 13 of the second arm 9. It is held by a holder 32 fixed to the arm 9 of. The joint portions, that is, between the connecting terminal 27 and the lower holder 32 whose relative distance changes due to rocking, and between the upper holder 32 and the holding shell 31 are coiled (curled). While being stretchable, a pair of retained odor 32
The space between the holding odor 31 and the connection terminal 30 is stretched linearly. The third signal line 26 is called a general cable and connects the connection terminal 30 and the motor 5 or the fuel amount indicator, etc. via a control panel (both not shown) located inside the gas station building. It is indicated by a broken line in the figure.

In the embodiment, the refueling hose 17 is moved up and down as appropriate by operating the main switch inside the refueling station building, operating the hand switch 20, or pulling the refueling worker.
Since the first signal line 24 is coiled and can be expanded and contracted, it expands and contracts up and down following the vertical movement of the refueling hose 17.

Further, when the refueling hose 17 is moved horizontally by pulling it horizontally, the second signal line 25 is connected to the first signal line 25,
Since it is placed along the second arms 8 and 9, it can sufficiently follow this horizontal movement without being manipulated or deformed. In particular, the first and second arms 8 and 9 not only prevent the suspension length from changing even if the refueling hose 17 moves horizontally, but also fix it to the movable connection terminal 27 that moves in accordance with the horizontal movement. The wiring distance to the connection terminal 30 also hardly changes, and there is no fear that the second signal line will be subjected to excessive pulling force or that it will come into contact with the case 2 due to excessive sagging. In the above embodiment, a case has been described in which the hose reel 4 is used to raise and lower the refueling hose 17, but it may be similarly applied to a system in which the refueling hose 17 is raised and lowered by sandwiching the refueling hose 17 between a pair of trochanters driven by an outer mower. It is something. Further, the arm mechanism may have approximately the same overall length regardless of its displacement position, and may be composed of three or more arms. As is clear from the above description, the present invention allows the signal line to follow the vertical movement and horizontal movement of the refueling hose without causing excessive pulling force or large manipulation deformation. This is extremely effective as a wiring treatment when using an external type. In particular, since the signal line is placed along the arm mechanism, it is extremely easy to handle the wiring in a narrow space such as an elevator storage case, and the arm mechanism can also be simply wired in a straight line, making it easy to wire in small areas. Wiring length can be shortened.
