Abstract
Description
[Technical Field]
[0001] The present invention relates to a fuel supply device that is installed at a gas station or the like and supplies fuel oil to a vehicle. [Background technology]
[0002] Fueling devices installed at gas stations and the like are equipped with fueling mechanisms for each type of fuel so that they can accommodate vehicles that use different types of fuel. For such fueling devices, the applicant has proposed a pump unit structure in which the fueling motor is mounted on top of the fueling pump, as a fueling device that can prevent oil leaking from the fueling pump from entering the fueling motor, and that simplifies the work of connecting the fueling pump to the piping of an underground tank and reduces the work time (see Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-105999 Summary of the Invention [Problem to be solved by the invention]
[0004] Although the above proposal is effective, if vibrations occur while the fuel supply device is being transported by truck, etc., the amplitude can become large because the pump unit has a high center of gravity. This can damage the pipe connecting the fuel supply pump and the flow meter, and the risk of residual gasoline leaking from the damaged pipe during the shipping confirmation inspection cannot be ruled out, leading to a fire.
[0005] The present invention has been made in consideration of the above problems, and aims to provide a simple configuration that reduces the vibration of the pump unit during transportation and improves the safety of the refueling device. [Means for solving the problem]
[0006] In order to achieve the above object, the present invention provides a refueling device comprising: a pump unit having a refueling pump and a refueling motor that drives the refueling pump; a flow meter connected to the refueling pump via piping; a refueling hose connected to the flow meter and having a refueling nozzle at its tip; a housing body having support pillars on each of the left and right sides and accommodating the pump unit; and support members connected to the left and right support pillars of the housing body and fixing the refueling motor.
[0007] According to the present invention, the fuel supply motor is fixed by support members connected to the left and right support columns of the housing body, so that the vibration of the pump unit when transporting the fuel supply device can be kept small, thereby increasing safety.
[0008] In the fuel supply device, by providing a front panel that covers the front of the pump unit and the flow meter, a nozzle hanger that is provided on the front panel and on which the fuel supply nozzle is hung, and a reinforcing member that is arranged on the back surface of the front panel to which the nozzle hanger is fixed, it is possible to reduce the force applied to the front panel when the fuel supply nozzle is hung on the nozzle hanger, and to prevent damage to the front panel.
[0009] Furthermore, by riveting the side of the reinforcing member to the side of the front panel at two locations, the force applied linearly to the front panel can be received by the surface, preventing the front panel from deforming into a dogleg.
[0010] The fuel supply device further includes a lever attached to the front panel that is rotated by a key, and a stopper attached to the main housing that engages with the lever, and the stopper prevents the lever from moving upward, thereby preventing the front panel from moving upward and coming off the main housing.
[0011] Furthermore, since the lever engages with the stopper on the left and right side surfaces of the main housing from the center of rotation of the lever, the stopper does not apply load to the lever when only one side of the lock is opened, preventing deformation of the lever.
[0012] Furthermore, the fuel supply device is provided with gutters formed on the left and right sides of the main housing and abutting the front panel, a hole formed at the lower end of the front panel, a convex portion provided at the lower end of the main housing and inserted into the hole, and a protrusion provided at the lower end of the front panel and abutting the gutters, so that the lower end of the front panel does not get inside the convex portion, preventing scratches on the front surface of the front panel and improving assembly ease. [Effects of the Invention]
[0013] As described above, according to the present invention, it is possible to provide a fuel supply device with a simple configuration, which has features such as keeping the amplitude of the pump unit small when transporting the fuel supply device and being highly safe.

[0015] Next, embodiments of the present invention will be described in detail with reference to the drawings.
[0016] Figure 1 shows one embodiment of a fuel supply device according to the present invention, and this fuel supply device 1 is equipped with a fuel supply mechanism (see Figure 2), a display 5, a fuel supply nozzle 6, etc. inside or on the surface of a housing main body 2. A safety joint 3 at the tip of the fuel supply pipe is disposed on the top of the housing main body 2, and the safety joint 3 and the fuel supply nozzle 6 are connected by a fuel supply hose 7. The back side of the fuel supply device 1 is configured in the same way as above.
[0017] The housing body 2 has a pair of support pillars 21, 22 on the left and right, and a bed 20 at the bottom for fixing to an island (not shown) with anchor bolts or the like. It also has a lower case 23 for storing the fuel supply system, etc., an upper case 24 above the lower case 23 for storing the display 5, and a top case 25 to which the safety coupling 3 is attached and to which piping for connecting the fuel supply hose 7 is arranged.
[0018] The refueling mechanism has the same configuration and operation as that provided in conventional refueling devices, and is composed of a refueling pump 12, a refueling motor 13, and a flow meter 14 shown in Fig. 2, and a refueling hose 7, a refueling nozzle 6, etc. shown in Fig. 1. This refueling mechanism is provided on each of the front and back sides of the refueling device 1 with three systems for, for example, high-octane gasoline, regular gasoline, and diesel.
[0019] A fuel supply hose 7 (see FIG. 1) is connected to the discharge port 14a of the flow meter 14 via a pipe 27. A fuel supply nozzle 6 attached to the tip of the fuel supply hose 7 is hung on a nozzle hanger 16 formed on a front panel 15 provided on the front and rear surfaces of the lower case 23.
[0020] 2 and 3, oil supply pumps 12 for supplying oil to different systems are mounted on a U-shaped base plate 26 within the lower case 23, and corresponding oil supply motors 13 are disposed above the oil supply pumps 12. The base plate 26 is attached to the bed 20. The oil supply pumps 12, oil supply motors 13, and base plate 26 are integrated into a pump unit to facilitate assembly.
[0021] A flow meter 14 is disposed above the fuel supply motor 13, and this flow meter 14 is attached to a beam plate 30 that forms the upper part of the lower case 23. The discharge port of the fuel supply pump 12 is connected to the corresponding inlet of the flow meter 14 via a pipe 28. A pipe 27 is connected to the discharge port of the flow meter 14, and the other end of the pipe 27 is led from the lower case 23 through the left and right support pillars 21 and 22 to the top case 25.
[0022] A support member 29 that fixes the fuel supply motor 13 with bolts B is connected to the left and right support columns 21, 22 via brackets 31-33, etc. The configuration that provides this support member 29 is one of the features of the present invention, and by fixing the fuel supply motor 13 with the support member 29, it is possible to keep the amplitude of the pump unit small when transporting the fuel supply device 1, prevent damage to the piping 28, etc., and increase safety during transportation.
[0023] The front panel 15 shown in Fig. 1 covers the front of the pump unit and the flow meter 14, and is provided with a nozzle hanger 16 for hanging the fuel nozzle 6 (see Fig. 1) as shown in Fig. 4. A reinforcing member 36 is provided horizontally on the back surface of the front panel 15, and the side surfaces of both ends of this reinforcing member 36 are fastened to the side surfaces of the front panel 15 at two locations with rivets 37 and 38.
[0024] The reinforcing member 36 reduces the force applied to the front panel 15 when the fuel nozzle 6 is hung on the nozzle hanger 16, thereby preventing damage to the front panel 15. Furthermore, by riveting the front panel 15 and the reinforcing member 36 at two locations, the force applied linearly to the front panel 15 can be received by a surface, preventing the front panel 15 from deforming into a dogleg.
[0025] As shown in Fig. 1, front panel 15 is provided with keys 40 at the left and right upper ends, respectively, which are used when attaching or detaching front panel 15 to or from lower case 23. As shown in Fig. 5, keys 40 have a plate-shaped lever 41. Meanwhile, lower case 23 is provided with stopper 42 that engages with lever 41, and stopper 42 has engagement hole 42a that is narrow at the top and wide at the bottom.
[0026] When attaching the front panel 15 to the lower case 23, from the state shown in Fig. 5(a), the lever 41 of the key 40 is inserted into the engagement hole 42a of the stopper 42, and as shown in Fig. 5(b), the lever 41 is positioned above the engagement hole 42a, thereby preventing the lever 41 from moving upward. This prevents the front panel 15 from moving upward and coming off the lower case 23.
[0027] 6(a), when only one side of the lock is opened, lever 41P comes into contact with stopper 42P fixed to lower case 23P, and there is a risk that lever 41P will be bent by stopper 42P. In the present invention, by changing the shape and attachment method of stopper 42 as described above, there is more room for the angle to which front panel 15 can be opened than in the past, and therefore stress is not applied to lever 41 when it comes into contact with stopper 42, and deformation of lever 41 can be prevented.
[0028] Next, a method for attaching front panel 15 to bed 20 will be described. Figure 6 shows a conventional method in which, when attaching front panel 55 to bed 20, a hole (not shown) formed in the bottom of front panel 55 is inserted into a protrusion 51 formed on the top of bed 20. At that time, lower end 55a of front panel 55 gets inside protrusion 51, causing the front surface of front panel 55 to come into contact with protrusion 51, which can scrape the paint on the front surface of front panel 55 and scratch the front surface of front panel 55.
[0029] 7, the present invention provides a protrusion 15a that protrudes rearward at the lower end of front panel 15, and by lowering (moving in the direction of the arrow) the front panel 15 while the lower end of the front panel 15 abuts against a gutter (vertical gutter) 52 that connects to the side of support 22 (and support 21), the lower end of the front panel 15 does not get inside protrusion 51, and hole 15b formed in the bottom of front panel 15 can be inserted into protrusion 51, making it possible to easily attach front panel 15 to bed 20. This prevents protrusion 51 from scraping off the paint on the design surface of front panel 15 and scratching the design surface, improving assembly ease.
