Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a suspended refueling device for refueling a vehicle with gasoline at a gasoline refueling station.

[Prior art]

In general, a suspended refueling system consists of a fixed pipe with one end opening into a liquid storage tank and the other end opening at an elevated location at the refueling station, and a hose reel rotatably housed inside the fixed piping, which is installed at an elevated location at the refueling station. a hose elevator, which is wound around a hose reel of the hose elevator, one end of which is connected to the other end of the fixed piping, and a refueling nozzle provided at the other end led out from a hose outlet formed in the hose elevator. The hose is made up of a

Then, when the gas station closes, the hose is fully wound and the refueling nozzle is raised to a storage position near the hose elevator, and when the gas station opens, the hose is raised to a storage position approximately 1.8 m above the ground.
m, and when refueling the vehicle, the entire hose is let out and the refueling nozzle is lowered to the refueling position.

By the way, in the case of a suspended refueling system configured in this way, the hose elevator is installed in the canopy, ceiling, etc. of the refueling station so as not to interfere with the running of the vehicle, and the hose elevator is installed at the outlet of the hose elevator. The lower surface where is formed is, for example, approximately 4.5 m above the ground. Therefore, a hose of a length that allows normal refueling work is wound around the hose reel, and the length of the hose to be fed out is approximately 5 m with some allowance.
is set to .

(Problem that the invention aims to solve) However, since the hose is lifted and lowered every day, its lifespan is 3 to 4 years, and if the hose is not inspected daily for damage, gasoline leakage etc. due to hose damage may occur. There is a risk of a serious accident.

However, the hose according to the prior art has a hose length that allows some leeway for the installation height of the hose elevator. Therefore, to check for damage to the hose, lower the refueling nozzle to the refueling position, use a special work vehicle equipped with a lift, and use a special work vehicle equipped with a lift to lower the refueling nozzle to the refueling position. A work vehicle must be brought in to carry out the inspection.
Another disadvantage is that the cover of the hose elevator must be opened to inspect the entire hose in a hidden area between the hose outlet and the hose reel. For this reason, daily inspections are difficult in practice, and the reality is that damage to the hoses is only discovered when oil leaks.

The present invention was developed in view of the problems of the conventional technology, and is a suspension system that allows the presence or absence of hose damage to be visually checked while on the ground during inspections, thereby eliminating the need for special work vehicles. The purpose of the present invention is to provide a type lubrication device.

[Means for solving problems]

In order to solve the above problems, the configuration adopted by the present invention consists of a fixed pipe with one end opening into the liquid storage tank and the other end opening at a high place at the gas station, and a fixed pipe installed at a high place at the gas station and rotating inside. a hose elevator having a hose reel, one end of which is wound around the hose reel of the hose elevator, connected to the other end of the fixed piping, and the other end led out from a hose outlet formed in the hose elevator; a main lift switch that instructs the hose elevator to raise and lower the refueling nozzle between a storage position near the hose elevator and a standby position at a predetermined height above the ground; In order to instruct the hose elevator to raise and lower the refueling nozzle between the standby position and a refueling position suitable for refueling work, a hand lift switch provided at or near the refueling nozzle, the storage position, and the standby position are provided. In a refueling device comprising a storage position detecting device, a standby position detecting device, and a refueling position detecting device provided in the hose elevator in order to detect the position and refueling position from the rotation of the hose reel, the hose is connected to the refueling nozzle. When in the refueling position, at least a portion of the hose located near the hose outlet is formed to a length that can be further extended to an inspection position that can be inspected from the ground, and the refueling nozzle is in the storage position, standby position, or refueling position. An inspection switch is provided that instructs the hose elevator to pass the hose and refueling nozzle through the refueling position to the inspection position and reel it up, and the hose elevator is configured to perform the inspection from rotation of the hose reel. The present invention is characterized in that an inspection position detection device for detecting the position is provided.

[Effect]

With this configuration, when the hose needs to be inspected, the hose reel of the hose elevator is rotated in the feeding direction by operating the inspection switch, and the hose and refueling nozzle are fed out past the refueling position. When the inspection position is reached, the inspection position detection device detects this and stops the rotation of the hose reel.
As a result, even if the refueling nozzle is lowered to the refueling position, the hoses near the hose outlet of the hose elevator or inside the hose elevator will also be lowered to the ground or close to the ground, making it difficult to inspect parts of the hose that are normally invisible while on the ground. can. When the inspection work is completed, the inspection switch can be operated again to rotate the hose reel of the hose elevator in the winding direction.

Embodiments of the present invention will be described in detail below with reference to FIGS. 1 to 3.

In the drawing, a building 2 with an office 2A is provided on a gas station site 1, and above the building 2 is a high place 2B such as a ceiling or a canopy. 3 is a fixed pipe installed along the building 2, one end 3A of the fixed pipe 3 opens into a liquid storage tank 4 buried underground in the site 1, and the other end 3B is connected to a hose described later from an elevated location 2B. It opens into the elevator 9. A pump drive motor 5 is located in the middle of the fixed pipe 3.
A pump 6 driven by a pump 6 and a flow meter 7 for measuring the amount of oil supplied are provided, and the measured value by the flow meter 7 is displayed by a display meter 8.

Reference numeral 9 denotes a hose elevator installed at a high point 2B of the building 2, and the hose elevator 9 has a hose outlet 1 on the bottom surface.
0A, a hollow fixed shaft (not shown) provided on the cover 10 and connected to the other end 3B of the fixed pipe 3; a hollow rotating shaft 11 (see FIGS. 2 and 3), and a hose reel 12 rotatably provided on the rotating shaft 11 integrally therewith.
, a lifting motor 13 , a reducer 14 that decelerates the rotation of the lifting motor 13 , and a chain 15 that transmits the rotation of the reducer 14 to the hose reel 12
and a lift adjuster 17 to which the rotation of the hose reel 12 is transmitted via a gear 16 provided on the rotating shaft 11, as shown in FIG.

Here, the elevation regulator 17 includes a reduction gear 18 that meshes with the gear 16, a small gear 19 that rotates integrally with the reduction gear 18, four gears 20A, 20B that mesh with the small gear 19, 20C, 20D
, cams 21A, 21B, 21C, 21D that rotate integrally with each of the gears 20A to 20D, and micro switches 22A, 22B, 22C, and 22D that are operated by each of the cams 21A to 21D. The switch 22A is for detecting the storage position, the micro switch 22B is for detecting the standby position,
The micro switch 22C is used to detect the refueling position, and the micro switch 22D is used to detect the hose inspection position.
is adjusted so that a refueling nozzle 25, which will be described later, is compatible with a storage position A, a standby position B, a refueling position C, and a hose inspection position D. Thus, cam 21A~
22D and microswitches 22A to 22D are combined to constitute a storage position detection device, a standby position detection device, a refueling position detection device, and an inspection position detection device according to this embodiment.

Further, 23 is a hose wound around the hose reel 12, and one end 23A of the hose 23 is connected to the rotating shaft 11 via a hose connector 24, and the rotating shaft 11 is connected to a fixed pipe via the above-mentioned fixed shaft. Therefore, the hose 23 is connected to the other end 3B of the fixed pipe 3.
It communicates with Further, a refueling nozzle 25 is provided at the other end 23B of the hose 23 led out from the hose outlet 10A formed on the lower surface of the cover 10.
is provided.

Here, the length of the hose 23 is, for example, 1.3 to 2 times the length of the hose that is fed out from the storage position to the refueling position as in the prior art, and the hose 23 is attached to the hose reel 12. It is wound so that it can be fed out and wound up. Therefore,
The hose 23 of this embodiment was wound around the hose reel 12, and the refueling nozzle 25 was raised to the vicinity of the hose elevator 9 at the storage position A, and was paid out so that the refueling nozzle 25 was lowered to a position approximately 1.8 m from the ground. Standby position B, refueling position C where the refueling nozzle 25 is fed out to the position where the vehicle should be refueled, and hose inspection position D where the hose 23 is completely fed out from the hose reel 12 to inspect the hose 23 (one point in Figure 1). The length between the refueling position C and the hose inspection position D is about twice the length between the storage position A and the refueling position C.

Further, 26 is a control panel installed in the office 2A of the building 2, and 27 is an elevator control panel installed outside the office 2A in an easily accessible location.
7 moves the refueling nozzle 25 from the storage position A to the standby position B
The main lowering switch 28 lowers the hose to the position B, the main raising switch 29 raises the hose 23 from the standby position B to the storage position A, the hose 23 is fully paid out so that the refueling nozzle 25 extends from the standby position B to the hose inspection position D, and the hose 23 is moved back to standby after inspection. It is equipped with an inspection switch 30 that operates to wind up to position B. 31 is a hand switch box provided at or near the refueling nozzle 25;
A hand lift switch is provided for raising and lowering the fuel tank between a standby position B and a refueling position C. The control panel 26 is electrically connected to an elevation control panel 27, a hand switch box 31, an elevation motor 13, an elevation regulator 17, and the like.

The present embodiment is configured as described above, but during normal refueling, the main lowering switch 2 of the elevation control panel 27 is
8. By operating the main lift switch 29, the refueling nozzle 25 is raised and lowered between the storage position A and the standby position B, and by operating the hand lift switch in the hand switch box 31, the refueling nozzle 25 is put on standby. It is raised and lowered between position B and refueling position C. The lifting operation at this time is carried out by the lifting motor 13.
The forward and reverse rotation of the hose reel 12 causes the hose reel 12 to rotate forward and backward through the reducer 14 and the chain 15, and the hose 23 wound around the hose reel 12 is fed out or wound up. The position detection at this time is performed by operating each of the microswitches 22A to 22C of the elevation regulator 17.

However, when inspecting the hose 23 for damage, the inspection switch 30 is operated. That is, when the inspection switch 30 is operated in the downward direction, the lifting motor 13 rotates downward, the hose 23 is paid out, and the refueling nozzle 25, which was at the standby position B, is extended to the hose inspection position D. This hose inspection position D is detected by a micro switch 22D, and when the micro switch 22D is activated, the downward rotation of the lifting motor 13 is stopped.

Then, at the hose inspection position D, the hose 23 is completely paid out, and the length of the hose 23 is approximately twice as long as that between the storage position A and the refueling position C. As a result, the part of the entire length of the hose 23 between the storage position A and the hot water supply position C lies on the ground of the site 1, and the hose 23 moves up and down.
It is possible to check for damage to the parts that are bent while on the ground.

Furthermore, after the inspection of the hose 23 is completed, when the inspection switch 30 is operated to the upward side, the lifting motor 13 rotates upward, and when the refueling nozzle 25 reaches the standby position B, the rotation of the lifting motor 13 stops. I'm starting to do that.

In addition, in this embodiment, the length of the hose 23 was described as being about twice the length of normal refueling, but if the installation conditions of the hose elevator 9 and the height of the worker are taken into consideration,
The length of the hose required for an operator on the ground to inspect the parts where the hose 23 is raised and lowered and bent for damage is the length of the hose that is required when the refueling nozzle 25 is lowered from the storage position A to the refueling position C. , the hose part located near the hose operation outlet 10A (cover 10
(including the inside) may be long enough to allow further descent to a position where it can be visually inspected by a worker on the ground. Further, the hose elevator 9 may be configured such that the suspension point of the hose 23 moves laterally by a predetermined distance, and may be a so-called laterally moving refueling device. Furthermore, although it has been described that the hose 23 is paid out and wound up by the corresponding length between the standby position B and the hose inspection position D by operating the inspection switch 30, the hose 23 is wound up between the storage position A and the hose inspection position D. , or it may be configured to be fed out between the refueling position C and the hose inspection position D and then wound up.

[Effect of idea]

The suspension type refueling device according to the present invention is as described in detail above, and when the inspection switch is operated to feed out the hose, the hose wound around the hose reel is wound around the hose elevator and is not visible at all times. The hose reel has a structure that allows the hose section to be fed out long enough to reach the inspection position where the inspection position detection device operates. The bent and coiled hose section can be inspected while on the ground, making daily inspections easier without the use of special work vehicles, etc., and ensuring the extent of damage and whether or not the hose needs to be replaced. can be visually observed,
Demonstrates excellent effectiveness as a safety measure.
