Description

DETAILED DESCRIPTION OF THE INVENTION [Technical field to which the invention pertains] The present invention relates to a ground-fixed refueling device used at gasoline refueling stations and the like.

[Prior art and its problems]

In such a fixed type refueling device, the base of the refueling port with a nozzle valve at the tip is fixed to the upper side of the case, and the length of the refueling port outside the case must be within a certain length by law. Because it is stipulated that it should not be
The refueling area was limited to a circle with the base as the center and the radius of the hose length.

[Purpose of the invention]

By moving the base support portion of the oil supply hose, the range of oil supply can be expanded compared to the conventional one, but in consideration of this situation, the present invention prevents the base support portion of the oil supply hose from performing other functions. It is possible to move 360 degrees on a horizontal plane, that is, in all directions, to the maximum extent possible, making it easier to refuel from any direction.Also, since a trolley is used as the movement mechanism for this purpose, operation is reliable and there are fewer failures. The purpose is to provide a refueling device.

[Key points of the invention]

However, according to the present invention, this purpose is achieved by expanding the refueling range by making the guide portion of the refueling hose arc-shaped.

[Embodiments of the invention]

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

Fig. 1 is a partially cutaway front view showing an embodiment of the refueling device of the present invention, and Fig. 2 is a cross-sectional plan view of the same. It is divided into a circular top case 4 whose upper edge is formed so as to protrude outward, and is provided with oil supply bosses 5 at appropriate positions around the periphery.

A refueling pump 6, a motor 7 connected to the pump 6, a flow meter 8, a flow pulse transmitter 9 attached to the flow meter 8, and a control box 1o containing a refueling control device are housed in the lower part of the lower case 2. Furthermore, a refueling amount indicator 11 and a nozzle switch 12, which will be described later, are housed in the upper part of the lower case 2. The pump 6 and the flow meter 8 are sequentially arranged in the middle of a fuel supply pipe 13 that communicates with an underground tank (not shown), and the fuel supply pipe 13 is raised inside the lower case 2 and its end protrudes into the top case 4. do.

Further, a nozzle hook 14 is formed on the upper outer side of the lower case 2, and a nozzle switch 12 that is activated when the nozzle valve 15 attached to the tip of the oil supply bow 5 is unlatched is placed near the nozzle hook 14.

As shown in FIG. 2, inside the top case 4, the oil supply pipe 1
3 is connected to the oil supply pipe 13' via a fixed joint 16 and extends to approximately the center of the case 4, and furthermore, a rigid pipe is connected to the end of this extending oil supply pipe 13' via a swivel joint 17. One end of the oil supply pipe 18 is connected, and the other end of the oil supply pipe 18 is made to protrude outward from an elongated hole 19 provided in an annular shape over the entire outer circumference of the case 4, and is connected to the base of the oil supply hose 5 and the joint part. Connect via 2o.

The swivel joint 17 is attached to a column 3 that is separately provided at the center of the case 4 in order to support the ceiling of the case 4 including the eaves part 25, and furthermore, when the oil supply pipe 18 rotates, A structure that prevents the support from colliding with the pillar 3 is used.

3 and 4 show details of this swivel joint 17,
A double pipe 17a surrounds the support column 3.

17b as the main body, the oil supply pipe 13' communicates with an outer pipe 17a fixed to the case 4 side via an inlet 17c, and the one-way pipe 17b projects from an annular groove 17d formed on the side of the outer pipe 17a. Connect to the refueling hose 18 in this manner. An annular groove 17e is formed on the lower surface of the inner tube 17b so as to correspond to the inlet 17c, and the inner tube 17b is watertightly joined to the outer tube 17a and is rotatable.

On the other hand, on the outside of the case 4, a guide rail 22 is formed in a circular endless shape, that is, an annular shape, using a channel member so that the opening surfaces thereof face each other so as to be parallel to the elongated hole 19. It was provided along the vicinity of the outer peripheral surface of No. 4.

Roller 23a with a bearing protruding in the lateral direction of the truck 23
A truck 23 is installed in the guide rail 22 so that it can run on the guide rail 22.

The truck 23 has a hole in the center, and the joint portion 20 is rotatably held through the hole.

In this way, the guide portion of the root support portion of the refueling hose 5 composed of the guide rail 22 and the trolley 23 is configured,
Furthermore, a boas guard 29 without corners is horizontally attached directly below the nozzle hook 14 on the side of the case 4 by using a metal half-ring so as to project slightly beyond the nozzle hook 14.

Next, to explain the usage and operation, to refuel, remove the nozzle valve 15 from the nozzle tJ)ld14 and insert it into the car's fuel filler port. As the oil supply pipe 18 rotates around the support 3 and the truck 23 runs on the guide rail 22, the joint 20 also moves accordingly, and the base support port 1 of the oil supply bow 5 in the case 4 moves accordingly. will be able to move freely. Therefore, the refueling area regulated by the support portion can be expanded in the horizontal direction over the entire 360° outer circumference of the refueling device 1.

A signal emitted from the nozzle switcher 2 when the nozzle valve 15 is removed is output to the motor 7 and the display meter 11 via the control equipment in the control box 10.
is returned to zero, and the pump driving motor 7 is driven to become ready for refueling.

Therefore, when the nozzle valve 15 is opened, oil is refilled, and the flow rate signal measured by the flow meter 8 and converted into a signal by the pulse transmitter 9 is counted by the control device in the control box 10, and the oil amount is displayed on the display meter 11. be done.

In this way, the root support part of the refueling bow can freely move horizontally 360° around the entire circumference of the refueling device 1, and unlike the case of the double type, only one type is displayed, so there is no possibility of misidentification. Case 2
Since it is cylindrical, refueling can be done in the same way from any position.

Furthermore, if the middle of the refueling water source 5 tries to touch the corner of the nozzle hook 14 during movement, the Beause guard 29 deflects this and prevents damage.

After refueling, when the nozzle valve 15 is hooked to the nozzle hook 14, the output from the nozzle switch 12 changes, the motor 7 and pump 6 are stopped, and the refueling operation is completed.

〔Effect of the invention〕

As described above, the refueling device of the present invention is a fixed refueling device in which the root support portion of the refueling port provided in the case can be moved horizontally through 360° without impairing other functions of the device. , it is possible to widen the refueling range to the maximum, making it easier to refuel from any direction, and further improving work efficiency.
