Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a suspended oil supply device.

(Prior Art) In the case of a so-called suspended refueling system, a hose storage case is provided at a high location of a refueling station such as a roof or a canopy, and a refueling hose is drawn out from the case to supply refueling.
Delivery units were in series or duplexes.

Recently, the demand for unleaded high-octane gasoline has increased, and it has become necessary for gas stations to measure and sell three types of fuel: gasoline, unleaded high-octane gasoline, and diesel oil. More and more places are installing fuel metering machines.

Therefore, in such gas stations, a new suspended refueling system having a series or two delivery units is installed in addition to the existing suspension type refueling system having a series or two delivery units as described above. Alternatively, instead of the existing suspended refueling system having a series or two delivery units as described above, three hose lifting devices are installed in a hose storage case as described in Japanese Patent Application Laid-Open No. 1614-1983. A method of replacing the oil supply system with a suspended type refueling system having three delivery units housed in parallel is being adopted.

(Problem to be solved by the invention) However, if a new suspended refueling system with a series or two delivery units is to be additionally installed within the filling station, there must be sufficient space within the filling station to accommodate the additional installation. Because of this, there were problems such as the limited number of gas stations where it could be applied.

In addition, in place of the existing suspended type oil supply system,
- When replacing with a suspended type refueling system having three delivery units as disclosed in Publication No. 1614, the hose storage case, that is, the delivery unit will be larger than the existing suspended type refueling system. Problems (the reachable position of the refueling nozzle during delivery is stipulated by law, and if three delivery units are installed in parallel, the reachable position will expand accordingly and there is a risk that the stipulations will not be met), and strength problems. It becomes difficult to use the existing canopy and hanging pipe from which the delivery unit is hung, and installation requires extensive renovation work, which is time-consuming and expensive. There was a problem.

This invention was created in view of the above problems, and by using the existing hanging pipe that attaches the hose storage case to the high place of the gas station,
To provide a refueling device in which a hose elevating device can be easily added and the hose can be used in a wide range of applications.

(Means for Solving the Problems) The suspended refueling device of the present invention has three hose lifting devices installed in one hose storage case that is installed at a high place in the gas station by a hanging pipe. Refueling hoses hang down from the lower surface of the case from each of the hose elevating devices so that the refueling hoses can be drawn out, and the position at which one of the refueling hoses is fed out moves along the longitudinal direction of the lower surface of the hose storage case. , in each of the hose lifting devices, two hose lifting devices are arranged in parallel to one hose lifting device to which the refueling hose whose feeding position moves is connected; The hose lifting and lowering devices are arranged in series with each other and provided within the hose storage case.

(Function) With the above configuration, it is possible to connect to the three hose lifting devices in one hose storage case by passing the oil pipes through the existing hanging pipes, and furthermore, it is possible to connect to three hose lifting devices in one hose storage case. By arranging the other two hose lifting devices in parallel, and the other two hose lifting devices in series with each other, hose storage becomes easier than when adding or replacing a conventional refueling device. The case can be made smaller and lighter. Furthermore, since three types of fuel can be measured and sold in one place, there is no need to guide cars due to differences in oil fluid. Since it can move freely along the longitudinal direction of the lower surface, it can be used in a wide range of refueling areas.

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

FIG. 1 is a system diagram of a fueling station equipped with the fueling device of the present invention.

1 is a hose storage case, hose storage case 1
is attached to a high place 2 of the gas station, such as a roof or a canopy, using existing, for example, two hanging pipes 3 and 3'.

The hose storage case 1 houses a hose moving type lifting device 4 and a hose fixed type lifting device 5 and 6.

Refueling hoses 7, 7, 7 each equipped with a refueling nozzle 13 hang down from the lower surface of the hose storage case 1 from each lifting device 4, 5, 6 so as to be able to be drawn out.

Oil piping 10, 10', 10'' connected to underground tanks 9, 9', 9'' via pump devices etc. The oil pipes 10, 10', 10'' are connected to the lifting devices 4, 5,
6, respectively.

The structure of the three elevating devices 4, 5, and 6 housed in the hose storage case 1 will be explained with reference to FIGS. 2 to 4.

A hose moving type elevating device 4 is attached to the left side of the flat box-shaped hose storage case 1 in the longitudinal direction of the case.

The hose lifting device 4 holds a refueling hose 7 wound around a reel 15 by an arm 11 that is rotatably mounted inside the hose storage case 1 and biased clockwise.
and a guide frame 1 slidably provided along a longitudinal elongated hole 1a provided on the bottom surface of the hose storage case 1.
2 are sequentially guided and suspended from the lower surface of the hose storage case 1, and a refueling nozzle 13 is connected to the hanging end.

Therefore, the feeding position of the refueling hose 7 is
By slidingly displacing the guide frame 12 along the elongated hole 1a, the lower surface of the hose storage case 1 (elongated hole 1a
(inside) moves in the longitudinal direction, expanding the refueling range.

The other hose lifting and lowering devices 5 and 6 both have the same structure, each reel 16 is provided in parallel with the reel 15, and each reel 16 is provided in series with each other in the longitudinal direction of the hose storage case 1. .
The hose 7 wound around each reel 15 passes through circular holes 1b, 1b formed in the lower surface of the hose storage case 1, hangs down below the hose storage case 1, and is connected to the refueling nozzle 13.

Since the refueling hoses 7 of the hose lifting devices 5 and 6 are drawn out through the circular holes 1b, the hose feeding positions are along the lower surface of the hose storage case 1, like the refueling hoses 7 of the hose lifting device 4. is provided almost fixedly without moving, and the refueling range is a range that swings around the circular hole 1b, and the refueling range is narrower than that of the hose lifting device 4 described above.

The relationship between the elongated hole 1a and the circular holes 1b, 1b is as follows.
As shown in the figure, a long hole 1a and two circular holes 1b,
1b are located at a distance from each other in the front and back, and the two circular holes 1b, 1b are located in parallel with the elongated hole 1a.

Each of the hose lifting devices 4, 5, and 6 is raised and lowered by driving a motor M by remote control, and is stopped at an appropriate height by a switch S or the like.

The light oil is set to be supplied through the hose lifting device 4. This is because light oil is demanded exclusively by customers with large vehicles, so by supplying fuel with a refueling hose that moves along the long hole 1a and has a large refueling range, this compensates for fluctuations in the parking position of large vehicles. Therefore, it is preferable.

The present embodiment is configured as described above, and although the refueling hose 7 is configured to be moved by the arm 11 and the guide frame 12 as in the present embodiment, the present invention is not limited to this. - Like the refueling device disclosed in Publication No. 56217, the hose lifting device 4
(Reel 15, motor M that drives the reel 15
and the switch S) itself may be moved.

Furthermore, the type of liquid supplied to each hose lifting device 4, 5, 6 is not limited to the above embodiment, and it goes without saying that the same liquid type may be supplied to a plurality of hose lifting devices. stomach.

(Effects of the invention) Since the present invention has the above configuration, it has the following effects.

(1) Three hose lifting devices capable of supplying different types of oil are provided in one case, so there is no need to guide the vehicle based on the different types of oil.

(2) Two hose lifting devices are arranged in parallel to one hose lifting device to which a refueling hose whose feeding position moves is connected, and the other two hose lifting devices are also connected in series with each other. Because of this arrangement, the hose storage case can be made smaller and lighter, making it possible to connect the hose storage case through three oil pipes within the existing hanging pipe, making construction easier and cheaper. It is.

(3) Gasoline and high-octane gasoline are often used by small and medium-sized vehicles, so they are supplied by hose lifting devices arranged in series with each other, and diesel oil is often used by large vehicles such as dump trucks, so they are supplied by the hose lifting device and If refueling is supplied using a hose moving lifting device arranged in parallel, the refueling conditions will change depending on the size of the vehicle, but this can be absorbed and work can be done more efficiently.
