Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a fueling station where a refueling nozzle is suspended from a rotatable delivery unit installed at a high place, with a position shifted from the center of rotation, and the refueling range is expanded. The purpose is to fix the delivery unit.

In order to expand the refueling range within the refueling area, a refueling device is used in which the refueling nozzle hangs down at a position offset from the center of rotation of the delivery unit, which is rotatably installed from a high place in the refueling station. In this type of refueling system, the delivery unit is simply held at a high location at the refueling station so that it can rotate freely via a bearing, etc., so when the delivery unit is hit by strong winds, it will rotate and the refueling nozzle will fall onto the refueling station site. There is a problem that collisions with obstacles inside the device may cause damage and malfunctions.

Furthermore, if a constant frictional force is applied to the rotation holding portion of the delivery unit in order to prevent the delivery unit from freely turning, the delivery unit must be rotated against this frictional force, which poses a problem in its operability. The present invention solves the above-mentioned problems by providing a delivery unit installed at a high place in a gas station with a brake machine next to it that regulates its rotation, and controlling the brake machine near the fuel nozzle hanging down from the delivery unit. The device is characterized in that a switch is provided to prevent the delivery unit from rotating freely when not in use.

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

At refueling stations, high places above the refueling area (ceilings, beams, etc.)
(or husband cover, etc.) 1 with a hanger 2, and the hanger 2
A support body 4 constituting the delivery unit is rotatably supported via a bearing 3. Inside the hanger 2, a pipe 5 connected to a fuel tank (not shown) is installed through the high point 1 of the fuel station, and is inserted into the bulge 4. On the other hand, within the crab body 4, a hose reel 6 is constructed by a shaft 7 at a position offset by a certain distance from the rotation center of the crab body 4 by the bearing 3, and one end of a hose 8 is wound around the shaft 7. A refueling nozzle 10 is connected via a universal joint 9 to
The other end of the hose 8 is connected to a rotary watertight joint provided on a hose reel 6 (not shown), and is connected to the pipe 5 via a rotary watertight joint 11 provided between the pipes 5' and 5. . A pulley 12 is attached to the shaft 7 of the hose reel 6, and a belt 15 is stretched between the pulley 12 and a pulley 14 of a motor 13 fixed to the inner wall of the weight body 4. The hose reel 6 is rotated by the drive of the hose reel 6, and the refueling nozzle 10 is raised and lowered.

The hose 8 from which the refueling nozzle 10 hangs is passed through an opening 4A closed to the weight body 4 at a position displaced by a certain distance from the center of rotation of the bulge 4 caused by the bearing 3. On the other hand, a disk 16 is fixed to the circumferential surface of the pipe 5 in the sparrow body 4, and a pair of pads 17 of an electromagnetic brake 17 are fixed to the cliff body 4 with the disk 16 in between.
A and 17B are arranged.

This electromagnetic brake 17 performs braking in a demagnetized state. Control of the electromagnetic brake 17 and the motor 1
The forward and reverse rotation control of No. 3 is performed by operating a switch in a hand switch box 18, which is provided on the hose 8 or the universal joint 9 near the refueling nozzle 10. That is, the switch box 18 is provided with a switch 19 for raising the refueling nozzle 10, a switch 20 for lowering the oil supply nozzle 10, and a set switch 21 for controlling the attachment and detachment of the disc 16 by the electromagnetic brake 17. A control circuit for the motor 13 is shown in FIG. 3, and a control circuit for the electromagnetic brake 17 is shown in FIG.

In FIG. 3, the motor 13 is controlled by three-phase alternating current, and branch wirings X', Y', and
Z is connected, and each wiring ×, Y, Z and X', Y', Z
' has switching contacts 22A, 23A inside, and magnets 22, 2 actuate each switching contact 22A, 23A.
The switches 19 and 20 are inserted into the power supply circuits 3 and 3, respectively. Therefore, when the switch 19 for ascending operation is closed, the magnet 22 is activated to close its contact 22A, and the motor rotates forward to wind up the hose 8, and when the switch 20 for descending operation is closed, the magnet 23 is activated. Then close the coin point 23A and turn the motor 13
The wiring connection to hose 8 is switched and reversed.
It lowers the In FIG. 4, the reset switch 21 is provided in the power supply circuit of the relay 24, and the first contact 24A of the relay 24 is connected to the electromagnetic brake 17.
The second contact 24B is connected to the control circuit of the oil supply amount display and gauge setting device 25 (not shown).

Therefore, when the reset switch 21 is closed, the electromagnetic brake 17 is released by the operation of the relay 24, and the grip of the disc 16 by the pads 17A and 17B is released.
As a result, the delivery unit is released, and at the same time, the IJ setting of the refueling amount display instruments is performed. Therefore, when the reset switch 21 is not operated, the disc 16 is held between the pads 17A and 178 of the electromagnetic brake 17, and the delivery unit is fixed. In the embodiments shown in FIGS. 1 and 2, the disk 16 is fixed between the pipe 5 inserted into the weight body 4, and the electromagnetic brake 17 fixed to the weight body 4 is applied to the disk 16. Although an example is shown in which braking is performed, the braking is not limited to this, or as shown in FIG. A disc 16 is fixed to the bracket 2A extending from the hanger 2, and an electromagnetic brake 17 is equipped with a pair of pads 17A and 17B for braking in a demagnetized state, and this electromagnetic brake is controlled by a control circuit shown in FIG. It may also be activated by

Further, the switch box 18 does not need to be provided on the hose, etc., and the switch box 18 is directly suspended from the screen 4 as shown in FIG. Alternatively, the electromagnetic brake 17 or the motor 14 may be controlled. In FIG. 5, other structural parts are given the same numbers as in FIG. 1, and the explanation thereof will be omitted. Note that the side of the brake is not limited to the electromagnetic brake shown in the embodiment, and its installation position is not limited to the mode shown in the embodiment. Any type of material can be used as long as it can be fixed appropriately in relation to the height of the building.

Since the present invention is configured as described above, it has the effects described below.

The delivery unit, which is rotatably held at a high location at the gas station, is braked by an electromagnetic brake or other brakes on the side, so it is fixed in position, and even if it is affected by strong winds during inconvenient times, the delivery unit as a whole will remain stable. There is no rotation, so it is possible to prevent the refueling nozzle from colliding with an article or vehicle and damaging it as in the conventional case.

Furthermore, according to the present invention, when rotating the delivery unit while holding the refueling hose in hand, the brake can be easily released by operating the hand switch, so the delivery unit can be configured to rotate as easily as possible using the bearing. There is no neck resistance when rotating, making it easy to operate.
