Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a ground-fixed refueling device used at gasoline refueling stations and the like.

[Conventional technology]

In such fixed refueling devices, the root of the refueling hose with a nozzle valve at the tip is usually fixed to the upper side of the case, and the length of the refueling hose outside the case must be within a certain length by law. Because of this, the refueling area was limited to a circle with the base as the center and the length of the hose as a radius.

On the other hand, by moving the base support portion of the refueling hose, the refueling range can be expanded compared to the conventional method.

For example, Japanese Utility Model Publication No. 51-38714 discloses a refueling machine in which a horizontally rotating arm rod is provided at the top of the refueling machine body, and a refueling hose is suspended from the tip of the arm rod.

As this arm rod rotates, the refueling hose is suspended and its base moves along the outer periphery of the top of the refueling machine body.

In addition, in Japanese Utility Model Publication No. 59-106900, an arm that can rotate around the base end is provided in the housing of the refueling machine, and by supporting the refueling hose halfway at the tip of this arm, the refueling hose that comes out from the housing is It is possible to rotate.

[Problem to be solved by the invention]

However, in the publication of Utility Model Application Publication No. 51-38714,
There is a rotating mechanism outside the main body of the refueling machine, so
It looks bad, and because the law stipulates that the length of the refueling hose outside the case must be within a certain length, the arm rod is also included within this certain length, which limits the refueling range. will not lead to expansion.

In addition, in the case of Utility Model Application No. 59-106900, although the base end of the rotatable arm and the base end of the refueling hose are close to each other, they are not the same, so the movement of the arm and the refueling hose can be adjusted. This is troublesome, and the refueling hose must be bent significantly above the arm. Accordingly, the housing case requires vertical clearance.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
The base support of the refueling hose can be moved as much as possible without interfering with other functions, making refueling work even easier, and using a trolley as the moving mechanism ensures reliable operation and fewer breakdowns. Our objective is to provide a refueling device that will become a reality.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention houses a refueling equipment such as a pump motor in a lower case, raises a refueling pipe, and protrudes its end to approximately the center of the top case. Connect one end of the first refueling hose to the swivel joint via a swivel joint, provide an opening of at least half the circumference at a location outside the lower case on the lower surface of the edge of the top case, provide a guide rail along the opening, and install a guide rail along the opening. A trolley running on a guide rail is provided, the trolley rotatably holds a joint connected to the other end of the first refueling hose, and a second refueling hose having a refueling nozzle at the tip is connected to the joint. The gist of the present invention is that the upper surface of the top case is supported on a straight line in the longitudinal center of the top case.

[Effect]

According to the invention, the first refueling hose in the top case is elastic and bends freely when force is applied;
In the curved state, rebound resilience is exerted.

Therefore, to refuel, remove the nozzle valve from the nozzle hook and insert it into the car's refueling port, but at this time, pull the second refueling hose by hand.
Since the truck travels on the guide rail, the joint also moves accordingly, so the root support portion of the second refueling hose in the top case is free to move accordingly. Therefore, the refueling area regulated by the support portion can be expanded to the front area of at least half of the outer circumference of the refueling device.

〔Example〕

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 a first embodiment of the oil supply device of the present invention, FIG. 2 is a side view of the same, and FIG.
The figure is a cross-sectional plan view of the same as above, and in this embodiment, the ground-fixed refueling device 1 is divided into a lower case 2, an upper case 3, and a top case 4 formed on the upper case 3 so as to protrude forward. , and is of a double type with oil supply hoses 5 and 5' on the left and right sides.

Inside the lower case 2, there is a fuel pump 6;
The upper case 3 houses a motor 7 connected to the flowmeter 8, a flow rate pulse transmitter 9 attached to the flowmeter 8, and a control box 10 containing a refueling control device. The nozzle switch 12 is stored. 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 connected inside the connecting column 30 of the lower case 2 and the upper case 3 and inside the upper case 3. 2, and its end protrudes into the top case 4.

In addition, a nozzle hook 14 is attached to the outside of the upper case 3.
A nozzle switch 12, which is operated by turning on and off a nozzle valve 15 attached to the tip of the oil supply hose 5, 5', is placed near the nozzle switch 12.

As shown in FIG. 3, inside the top case 4, the end of the oil supply pipe 13 is connected to the oil supply pipe 13' via a fixed joint 16, and extends to approximately the center of the case 4, and this extension is further connected to the oil supply pipe 13' through a fixed joint 16. One end of a refueling hose 18 using a wire-reinforced hose is connected to the end of the refueling pipe 13' via a swivel joint 17, and the other end of the refueling hose 18 is connected to a length provided on the outer peripheral side of the case 4. It projects outward from the hole 19 and is connected to the base of the refueling hose 5 via the joint part 20. Note that the oil supply pipe 13' side of the front swivel joint 17 is fixed to the case 4 side.

On the other hand, a guide rail 22 is provided on the outside of the case 4 and parallel to the elongated hole 19 by using a channel member with the opening surfaces facing each other. Since the refueling device 1 of this embodiment is of a double type, the same mechanism as described above is connected to the refueling hose 5' in cases 2, 3,
There is another set on the opposite side of 4, and there is also a display meter 11,
11' are provided on both the front and back sides of the refueling machine 1,
Even inside the case 4, the fixed joint 16, the oil supply pipe 13',
The swivel joint 17, the oil supply hose 18, and the guide rail 22 are provided as a pair symmetrically from the center, and in particular, the swivel joints 17 are placed close to each other at the center of the case 4.

The guide rail 22 is provided with a length such that it can rotate about half a circumference along the vicinity of the outer peripheral surface of the case 4, and both ends of the overall U-shape are located at the center of the front (back) of the oil supply device 1. A buffer stopper 24 made of rubber or a spring is attached to the end. The ends of both guide rails 22, 22 are opposed to each other, and the corresponding indicators 11, 11' are positioned just inside thereof, respectively.

The rollers 23a with bearings protruding in the lateral direction of the truck 23 are placed within the guide rail 22, and the roller 23a of the truck 23 is
3 is installed on the guide rail 22 so that it can run. Note that the guide rail 22 is formed to draw a rounded curve at the corner of the case 4 so that the cart 23 can run smoothly. The truck 23 has a hole in the center, through which the joint portion 20 is rotatably held.

In this way, the guide rail 22 and the truck 2
3 constitutes the root support part of the refueling hoses 5, 5',
The upper part of this guide rail 22 is covered with an eaves part 25 that is integrated with the case 4. Furthermore, a hose guard 29 without corners is horizontally attached directly below the nozzle hook 14 on the side of the case 4 using a metal half-ring so as to project slightly beyond the nozzle hook 14.

Furthermore, since the hoses 18, 18 are bent in the same direction as shown in FIG. There is no contact inside.

Next, how to use and operate the hose 18 inside the case 4 is elastic, and when force is applied, it bends freely, and when it is bent, it exerts a repulsion elastic force.

Therefore, in order to refuel, the nozzle valve 15 is removed from the nozzle hook 14 and inserted into the refueling port of the automobile. At this time, by pulling the hoses 5, 5' by hand, the trolley 23 is moved to the guide rail 22. As the vehicle travels, the joint portion 20 also moves accordingly, and the root support portions of the fuel supply hoses 5, 5' in the case 4 are free to move accordingly. Then,
The refueling area regulated by the support portion can be expanded to half the front (rear) side and the side surface of the refueling device 1, that is, the front area of the outer half.

A signal emitted from the nozzle switch 12 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, and the display meter 11 returns to zero and the pump drive motor 7 is turned on. It is driven and ready for refueling. Therefore, when the nozzle valve 15 is opened, oil is supplied, 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 supply amount is displayed on the display meter 11. Is displayed.

In this way, for refueling, the root parts of the hoses 5 and 5' can freely move around the outer half of the case 4, but for example, the hoses 5 cannot be moved to the front of the display meters 11' other than the corresponding display meters 11. Therefore, even if the hoses 5 and 5' supply different types of oil, the possibility of misreading the display can be prevented.

Furthermore, if the trolley 23 and the joint 20 are located at one end of the guide rail 22 and refueling is performed in front of the other end, the middle of the refueling hoses 5, 5' may come into contact with the corner of the nozzle hook 14. The hose guard 29 then deflects this and prevents damage.

After refueling, set the nozzle valve 15 to the nozzle hook 1.
4, the output from the nozzle switch 12 changes, the motor 7 and pump 6 stop, and the entire 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 part of the refueling hose provided in the case can be moved horizontally to the maximum extent possible without impairing other functions of the device, thereby increasing the refueling range. It is possible to further improve work efficiency by expanding the number of parts as much as possible, and since a trolley is used, there are fewer breakdowns and the operation can be performed easily and reliably.
