Description

[Detailed Description of the Invention] The present invention relates to a lateral movement type refueling device in which the refueling hose is moved laterally to expand the refueling range.

For example, at a gasoline filling station, a switch for raising and lowering a hose lifting device that raises and lowers a refueling hose, and for returning to zero, is installed between the refueling hose and the refueling nozzle, and by operating the switch, the switch is installed in an office, etc. The hoisting motor in the lifting device is driven via the control device, which raises and lowers the refueling hose, or resets the display device that displays the amount of refueling, etc. to zero.

In this case, since the refueling hose includes an electric wire that connects the control device and the switch, there is a problem in that the area of the flow path within the refueling hose becomes small and the flow rate decreases.

Furthermore, when the electric wires are installed inside, the refueling hose moves not only vertically but also horizontally, which causes the problem that the electric wires are easily broken.

For this purpose, it is conceivable to form the electric wire or cable into a spiral shape and wrap it around the outer circumference of the refueling hose, but this may cause deterioration due to oil or moisture adhesion during refueling operations, or damage due to contact with other surfaces. There was a risk that this would happen.

Furthermore, since the electric wire or cable itself is formed into a spiral shape and wrapped around the outer circumference of the refueling hose, the electric wire or cable is normally forced downward (toward the switch side) due to its own weight.
The electric wires 2 hang down and pile up as shown at A in Fig. 6, which not only makes the switch operable poorly, but also causes the electric wires 2 in the upper part (on the side of the hose lifting mechanism 8) to hang down as shown at B in Fig. 6. (or the cable) will come into direct contact with the refueling hose 6 in a reduced diameter and pulled downward state.

For this reason, when the refueling hose 6 is let out, this electric wire 2
(or the cable) becomes a brake, and the refueling hose 6 is not paid out, and the refueling hose 6 is bent inside the case body 4 of the hose lifting device 8, and the refueling nozzle 5 does not descend to the refueling position. Or, again,
There is a problem in that the electric wire 2 (or cable) resists the force of feeding out the refueling hose 6 and breaks (refer to the explanatory part of FIG. 4 for the reference numbers of other parts in FIG. 6).

The present invention solves these problems by loosely fitting an electric wire into a bendable tube, forming the tube in a spiral shape, and causing no hindrance to the expansion and contraction of the electric wire.
It is structured so that it can also be protected from the outside, and is wound around a refueling hose, one end of which is connected to a horizontally movable trolley, and the other end is fixed to a hand switch. It is characterized by:

Hereinafter, implementation of the present invention will be explained with reference to the drawings.

First, to describe the curl tube used in the present invention, in FIG. 1, reference numeral 1 is a flexible tube made of resin such as nylon #11. ,2. ... are installed inside with a gap between them and the tube 1, and the tube 1 is heated and formed into a spiral shape together with the electric wire 2, as shown in FIG.

Here, tube 1 and electric wires 2, 2. Because there is a gap between wires 2, 2. The wires 2, 2, . ...and will not be bent suddenly.

Furthermore, as shown in FIG. 2, when the tube 4 is wrapped around the outer periphery of the refueling hose 6, the tube 4 tries to maintain its formed shape, so it sag downward due to its own weight, and the upper part of the tube 4 tends to keep its shape. It does not come into direct contact with the refueling hose when the diameter is reduced and it is pulled downward.

Note that a plurality of electric wires 2, 2. ... may be bundled and placed inside the tube 1 as a single cable as shown in FIG.

Next, the installation state of the curl tube described above will be described with reference to FIG.

First, the refueling device has a case main body 4 installed at a high place 3 of a refueling station, and the case main body 4 has a built-in hose lifting mechanism that raises and lowers a refueling hose 6 having a refueling nozzle 5 by forward and reverse rotation of a motor 7. .

Further, the case body 4 has a built-in moving mechanism 9 that moves the refueling hose outlet from the lifting mechanism 8 in the horizontal direction.
An arm groove 1 consisting of an arcuate portion 11a that is parallel to the arcuate portion 11a and rotatably supported by the case body 4, and a linear portion 11b that is rotatably supported by the arcuate portion 11a.
1 and a cart 13 that moves horizontally along a rail 12 laid on the bottom of the case body 4 to move the free end of the arm groove 11 in the horizontal direction. ... and is suspended below the bottom opening of the case body 4.

Then, a refueling hose 6 exposed downward from the case body 4
is equipped with a spirally formed tube 1 having a diameter larger than that of the refueling hose 6, and a guide rod 15 serving as a guide suspended horizontally near the bottom of the case body 4 has a diameter of the tube 1 ( A spiral tube 1 having a smaller diameter than the coil diameter is supported.

Here, both tubes 1, 1' use one continuous tube, and therefore internal electric wires 2, 2. ... are electrically connected.

In this case, the intersection of the horizontal tube 1' and the vertical tube 1 will be explained based on FIG.
1' is the bottom opening 4 of the case body 4 during movement.
A cylindrical guide 18 is in contact with the brush 17 provided in a.
It is placed on the fixed base 16 and fixed to the fixed base 16 with a clamp 19.

The cylindrical guide 18 is connected to a nut 20 fixed to the cart 13.
The tube 1 is fixed by a fixing gasket 21.

The clamp 19 and the fixing gasket 21 keep the straight section between the tubes 1 and 1' parallel to the oil supply hose 6.

The tubes 1 and 1' in the present invention are one resin tube in which an electric wire is housed, and both ends are spirally formed with a straight portion left in the middle.

The inner end of the tube on the side of the refueling nozzle 5 is also formed into a straight line, and this part extends downward along the refueling hose 6, and is inserted, for example, into the hand switch box 22 attached to the lower part of the refueling hose 6 from its upper surface. Insert the hand switch box 2
It is fixed at 2.

The electric wires 2, 2 of the tube 1 have a diameter larger than that of the refueling hose 6 and are spirally shaped. ... are electrically connected to the switch in the hand switch box 22 of the refueling nozzle 5, and are wires 2, 2, . ... are electrically connected through the case body 4 to a control device installed in the office of the gas station, on the wall of the office, on the firewall, etc.

Here, the control device starts the motor 7, starts and stops the motor that drives the refueling pump, returns the display device for the amount of refueling, etc. It emits a signal.

In this case, the refueling hose 6 is manually held on the trolley 1.
By laterally moving the refueling hose 3 along the race 12 in the left-right direction in the drawing, the outlet of the refueling hose 6 is changed in the horizontal direction, and as a result, the refueling range is expanded.

At this time, the tube 1 will expand and contract along the guide rod 15.

In this case, the diameter for winding the tube 1' is small, so the space is small, and the case body 4 does not have to be made large, and since the tube 1' is made of resin, its shape does not collapse. There is no possibility of getting caught in the trolley 13.

Furthermore, when the hose elevating mechanism 8 raises and lowers the refueling hose 6, the tube 1 expands and contracts.

At this time, since the tube 1 is externally covered by the refueling hose 6, the internal flow path is not narrowed.

In addition, the tube 4 is larger than the hose diameter of the refueling hose 6 and is formed into a spiral shape, so that its shape does not easily collapse. The main body 4 side) is reduced in diameter and does not come into direct contact with the refueling hose 6 when it is pulled downward, so that the refueling hose 6 can be let out from the case main body 4 especially in order to lower the refueling nozzle 5. At this time, the contact part acts as a brake, preventing the refueling hose 6 from being paid out.
It will not bend inside the case body 4.

Furthermore, since the tubes 1 and 1' are one continuous piece, there is no need to connect the tubes 1 and 1' at the carriage 13 of the case body 4, and there is no need to provide a connection terminal, a protective cover, etc. at the connection part. do not have.

Further, in the above embodiment, the horizontal tube 1' is described as being externally attached to the guide rod 15, but instead of the guide rod, a cable, a cylinder with a notch in the longitudinal direction, etc. may be used. Furthermore, multiple rings are slidably provided on the guide rod,
Tubes 1' may be attached to this ring at predetermined intervals.

■ In this invention, the electric wire is loosely fitted into the tube and wound around the refueling hose, so the movement of the refueling hose does not interfere with the expansion and contraction of the tube and the electric wire. Replacement/repair is also easy.

Even if the tube is wound around the outer periphery of the refueling hose, the flow rate of fluid flowing through the refueling hose will not be reduced or pressure loss will not occur.

■ A tube made of resin that maintains its shape in its natural state is molded into a bendable spiral with a diameter larger than the hose diameter of the refueling hose, and is wound around the outer circumference of the refueling hose. Since the electric wires are internally arranged with a gap between them, unlike in the past, the electric wires or cables do not normally shrink in diameter due to their own weight and come into contact with the refueling hose, and act as a brake when the refueling hose goes up and down.
Furthermore, there is no need to worry about wire breakage, and since electric wires or cables do not pile up near the switch box as in the conventional case, it becomes easier to operate the switch.

■ Both ends are formed into a straight line and fixed to the trolley and hand switch box, so it can be easily fixed to the trolley and hand switch box, and will not adversely affect the part wound around the refueling hose. .

■ Since the straight parts are parallel to the refueling hose, the spiral part between the straight parts can smoothly expand and contract when the refueling hose is raised and lowered.

The part of the hand switch box prevents the tube from slipping downward. The part that is fixed to the trolley is also parallel to the refueling hose, so when the trolley moves, the tube itself will also move laterally with the trolley. This will not adversely affect the lifting and lowering of the refueling hose.

■ Since the fixed part of the truck is straight, it is easy to install guides such as guide tubes.
