Description

DETAILED DESCRIPTION OF THE INVENTION An object of the present invention is to expand the refueling range in a refueling system in which a refueling nozzle is suspended from a high place in a refueling station.

Conventionally, in so-called ceiling-hanging refueling systems in which the refueling nozzle is suspended from a high place at a refueling station, a reel is installed at a high place in the refueling station around which the refueling hose is wound, and the refueling hose is pulled out from the reel and then Refueling work was performed by lowering the refueling nozzle at the lower end.

Therefore, the refueling range that can be refueled by the refueling nozzle is limited to a certain circular range centered on the point at which the hose is pulled out from the reel. The present invention solves the above-mentioned problems by suspending a refueling hose hanging from a high place at a refueling station from a hanger guided by an annular rail installed at a high place on the ceiling. This is characterized by expanding the refueling range by displacing the . Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, a case 3 of a refueling hose storage device 2 is attached to a high place 1 of the refueling station, such as the ceiling, beam, or end of the refueling station, and a hose reel 4 and the hose reel 4 are rotationally driven inside the case 3. A motor 5 is built-in. on the other hand,
A fuel pipe 7 with one end connected to a fuel storage tank (not shown) is installed along the wall of the gas station building 6, and the pipe 7 rises upwards inside the gas station building 6, and further extends to the high point 1 of the gas station building. The pipe is connected along the inside of the case 3, passes through the center of the hose reel 4, and further extends along the shaft 4 of the hose reel 4.
Refueling hose 8 wrapped around the circumference of the reel through A
A refueling nozzle 9 is connected to the lower end of the refueling hose 8.
is installed. A groove-shaped annular rail 10 is laid on the bottom surface of the case 3, and a hanger 12 equipped with rollers 11 guided along the river is attached to the rail 1.
It is suspended from 0. Although a closed-loop annular rail is shown as the annular rail 10, the annular rail 10 is not limited to this. For example, an annular rail with a rectangular shape, an elliptical shape, etc. may be used, and an arc-shaped or circular rail that does not form a closed loop may also be used. It may be a semi-circular rail such as a letter shape, and these annular rails and semi-circular rails are also included in the annular rail of the present invention. The hanger 12 includes a hose inlet 13A that opens upward at the inner layer of the rail 10, for example, at the axial center position, and a hose that opens at a position offset from the hose inlet 13A, for example, at a position almost directly below the rail 10. Outlet 13
A tubular hose guide 13 equipped with a tube B is fixed, and the refueling hose 8 is passed through the hose guide 13 and suspended below from the lower line outlet 13A. A large number of rollers 14, 14, . . . for guiding the refueling hose 8 are arranged on the inner bottom surface of the hose guide 13 along the moving direction of the hose. Further, a pump 16 driven by a pump motor 15 and a flow meter 17 are connected to the middle of the oil supply pipe 7, and the flow meter 17 further transmits a flow rate signal to a flow rate display meter provided at an appropriate location. A transmitting mechanism 18 is provided for transmitting.

Note that forward/reverse changeover switches 19 and 20 for the motor 5 that drives the hose reel 4 are provided on the refueling hose 8 at or near the refueling nozzle 9 and on the wall of the building 6, respectively. In the embodiment, a vehicle enters the premises of a gas station and is stopped below the case 3 of the fuel hose storage device 2.

The refueling hose 8 is normally wound up on the reel 4 and is waiting at an upper position, but in this state, by operating the switch 20 on the wall of the lotus house 6, the motor 5 is driven so that it does not interfere with the movement of the vehicle. (approximately 1.8 hours above ground level), then operate the switch 19 provided on the refueling nozzle 9 to extend the hose 8 further and lower it to the position where refueling is possible.
When this refueling hose 8 or refueling nozzle 9 is pulled toward the vehicle, the hanger 12 moves within the groove of the seal 10 and the position of the hanging point of the refueling nozzle 9 is displaced, causing it to move closer to the vehicle. Refueling work can be performed by bringing the refueling nozzle 9 closer to the area. After the refueling operation is completed, the rotation of the motor 5 is reversed by operating the switch 19 to drive the upper reel 4, and the refueling hose 8 is wound around the circumference of the upper reel, so that the refueling nozzle 9 is moved upward so that it does not interfere with the movement of the vehicle. If necessary, by operating the switch 20 on the wall of the lotus house 6, the refueling hose 8 is wound around the cylindrical surface of the reel 4, and the refueling nozzle 9 is placed on standby at the upper end position.

In the embodiments described above, the hanger can be moved to any position within the range of the annular rail 10 to change the position of the hanging point of the refueling nozzle 9, thereby expanding the refueling range. The hanger 1 along the rail 10 is capable of 36 or more rotations over its entire range.
1, the hose 8 will be twisted in accordance with the displacement.

However, when the grip on the refueling nozzle 9 is released, the twist returns to the original position due to the elastic force of the hose 8 itself. In the above embodiments, an example in which the hose 8 is wound around or pulled out from the circumferential surface of the hose reel 4 as a lifting device for the refueling hose 8 has been described, but another embodiment will be described with reference to FIG. 2.

In FIG. 2, a refueling hose 8 is suspended downward from a support plate 21 provided on a hose reel storage device 2, and a pair of rollers 22, 22 for gripping the refueling hose 8 is installed on the support plate 21, and one of the rollers 22 is installed on the support plate 21. Roller 22 is connected to motor 5
A switch 19 provided on the refueling nozzle 9 or the refueling hose 8 near the refueling nozzle 9 or a switch 2 provided on the wall of the refueling nozzle 6 switches the motor 5 between normal and reverse rotation.
This may be performed by operating 0. Other constituent parts that are the same as those in FIG. 1 are given the same numbers and their explanations will be omitted. In the embodiments shown in FIGS. 1 and 2 above, the hanger 1
2, and in order to guide the refueling hose 8 through the guide 13, it is possible to smoothly displace the suspension point along the rail 10 without causing strain in guiding the hose. can.

Further, in the embodiment shown in FIG. It may be supported by a hanger 25, and this hanger 25 may hold a hose guide 26 through which the refueling hose 8 is passed, as shown in the opening in the figure.

Furthermore, in the above embodiment, the hose inlet 13A is closed at the koji center position of the seal 10, but it is not necessarily necessary to open the hose inlet 13A at the koji center position. At least, it is sufficient if the entrance is placed inward of the rail 10. Since the present invention is configured as described above, the refueling hose 8 is suspended from a point at a high place in the refueling station.
hangers 12 and 25 suspended from the annular rails 10 and 23
Since the hangers 12 and 25 are suspended over the entire range of the annular rails 10 and 23, the range of oil supply can be significantly expanded by changing the hanging points of the hangers 12 and 25.

In addition, the present invention does not require a motor for rotating the hose guide and an arm for pivotally connecting the hose guide to the case, so the case can be made as small as possible depending on the size of the annular rail. Can be designed. According to the present invention, since the refueling hose hangs directly below the hanger suspended from the rails 10 and 23, it is manually connected to the rails 10 and 23.
Even if the hanger 12, 25 is rotated along the
No excessive force is applied to the nozzle 9, and the position of the nozzle 9 can be moved smoothly. In this case, it is sufficient to turn only the hose wire outlet side of the hose guide, and since the inertia at the time of turning is small by 4 mm, the hose guide can be accurately stopped at a desired turning position. In addition, since the hose guide's hose inlet is formed at the chest position of the annular rail, the position of the hose inlet does not change even when turning, and the refueling hose can always smoothly go in and out of the hose inlet. It will be held in Since it is only necessary to hang the hose guide from the annular rail via the hanger,
It is lightweight and easy to install, and there is no need to support and reinforce the hose guide with hanging beams, so it can be manufactured at low cost. Furthermore, the hose guide 13 attached to the hanger 12, 25,
By hanging the refueling hose 8 through the inside of the refueling hose 26, the refueling hose 8 can be smoothly moved up and down. Since the hose guide is housed in the case, it has a good appearance and does not move along the annular rail even if a strong wind blows, for example.
