Description

[Detailed Description of the Invention] The present invention relates to a suspended type refueling device in which a refueling hose is suspended from a high place at a refueling station, and more specifically, to an improvement of a hand switch section provided on the refueling hose for lifting and lowering operations.

In this type of refueling device, the refueling hose is usually provided with a hand switch for lifting and lowering the refueling hose near the refueling nozzle, and when the hand switch is operated, the refueling nozzle installed at the end of the refueling hose moves toward the vehicle. The refueling hose is raised and lowered so that it can be placed between a refueling standby position and a refueling possible position where it does not interfere with the refueling.

In the refueling standby position, the refueling nozzle is located approximately 2 m above the ground and the refueling worker cannot directly operate the hand switch, so the refueling hose lowering switch must be operated from the hand switch. A tensioning means for refueling is suspended within reach of the refueling operator.

Conventionally, this tensioning means is provided in a main body of a hand-held switch part and has a guide hole that extends in the vertical direction thereof and opens at the lower end of the main body, and is slidably inserted into the guide hole and held by the main body, a rod member associated with the lowering switch;
It consists of a cable such as a chain connected to the lower end of the rod member and suspended from the rod member, but since the rod member protrudes from the lower end surface of the main body, the following inconveniences have occurred. .

In other words, when you grip the cable and pull it diagonally, the tensile force becomes a bending force on the rod member, and the rod member acts to bend the hose, causing the hose to bend and the rod member to bend. It does not act as a sliding force on the rod member until it is oriented to a certain extent in the direction of the tensile force.

Therefore, in order to pull down the rod member, at least a force for bending the hose and a force for sliding the rod member are required, which requires a large amount of operating force.

Even if the rod member slides while the hose is bent and the hose lowering switch is activated, the refueling nozzle at the end of the hose will come down while swinging. There is a high possibility that the machine will hit and damage nearby vehicles, such as those waiting for refueling, and it will also be difficult for workers to catch the descending refueling nozzle. .

Therefore, in order to lower the hose from the refueling standby position to the refueling possible position of the refueling nozzle, the cable must be pulled almost vertically downward, resulting in extremely poor operability.

The present invention solves the above-mentioned problems, and is characterized in that the rod member and the cable are connected within the guide hole of the main body of the hand switch section.

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

In FIG. 1, a case 2 is installed at a high place 1 such as a ceiling, a beam, a canopy, etc. of a gas station, and a hose reel 3 as a refueling hose lifting device is disposed within the case 2.

The refueling hose 4 wound around the hose reel 3 is connected to the case 2.
It passes through and hangs down, and a refueling nozzle 5 is connected to its tip.

Of course, each of the fuel hoses 4 is connected to an underground storage tank via piping, although not shown.

The refueling hose 4 is provided with a hand switch section 6 near the refueling nozzle 5 for raising and lowering the refueling hose 4, that is, for rotating the hose reel 3 in the forward and reverse directions.

As shown in FIG. 2, the hand switch section 6 has a main body 7 fixed to the refueling hose 4 holding various switches, and in the embodiment, the various switch groups are arranged from top to bottom. In order, for example, in addition to a lower switch 8, a lower switch 9, and a reset switch 10 for returning a flow rate indicator (not shown) to zero, each of which is a push button type,
It is comprised of another lowering switch 11 operated by a tension operation means to be described later.

The lowering switch 11 and the pull operation means will be described in detail with reference to FIG.
A rod 13 is fitted into 2 so as to be vertically movable.

The guide hole 12 has a small diameter part 12a at the top and a large diameter part 1 at the bottom.
2b, the rod 13 is substantially slidably guided by this small diameter portion 12a, and a flange portion 13a formed at the lower end of the rod 13 forms a stepped portion 1 between both ends 12a and 12b.
By coming into contact with 2c, upward movement beyond a predetermined value is restricted.

This rod 13 has its upper end facing the actuator 11a of the lowering switch 11 housed in the main body 6, and is normally urged upward by a spring 14 and comes into contact with the actuator 11a. When the rod 13 is lowered by a predetermined stroke from this position, the lowering switch 11 is turned ON.

The length of the large diameter portion 12b of the guide hole 12 is longer than the stroke of the rod 13 required to turn on and off the lowering switch 11.

In other words, the lower end of the rod 13 is always connected to the guide hole 12.
It is located inside the main body 7 and does not protrude downward from the lower end surface of the main body 7.

The upper end of a cable 15 such as a chain or wire extending into the large diameter portion 12b is connected to the lower end surface of the rod 13, and the cable 15 hanging from the rod 13 is connected to the lower end surface of the main body 7. It extends slightly downward.

A rod-shaped grip member 16 made of an elastic material is connected to the lower end of the cable 15, and a flange portion 16a is formed at the lower end to prevent slipping during a pulling operation.

Of course, this grip member 16 is located below the refueling nozzle 5, and when the refueling nozzle 5 is in the refueling standby position,
It can be easily held by a refueling worker.

Note that, without separately providing this grip member 16, the cable 1
5 may be made sufficiently long so that it can be directly held by the refueling operator, and the lower end of this sufficiently long cable 15 may be covered with a cylindrical gripping member made of an elastic member. Good too.

In the figure, 17 is a spring receiver fitted to the upper end of the rod 13;
is a retaining ring that restricts upward movement of the spring receiver 17, and downward displacement of the rod 13 beyond a predetermined value is regulated by the retaining ring 18 coming into contact with the inner wall of the main body 7 via the spring receiver 17. Ru.

In the embodiment, when a refueling worker grasps and pulls the grip member 16, the rod 13 is pushed down and the lowering switch 11 is turned on, and a motor (not shown) moves the hose reel 3 as shown in FIG. Rotate in the direction.

By the rotation of this hose reel 3, the refueling hose 4 is
is fed out, and the refueling hose 4 (refueling nozzle 5) is lowered to a position where the hand switch section 6 can be directly operated.

Normally, refueling is possible in this state, but if the refueling nozzle 5 is far from the vehicle's refueling port (not shown), the lowering switch 8 may be pressed to further extend the refueling hose 4.

After the refueling work is completed, the lift switch 9 may be pressed to return the vehicle to the refueling standby position.

Here, when the grip member 16 is pulled diagonally, the cable 1
Due to the bending of the rod 5, this oblique force is stopped at the lower opening end of the guide hole 12, and only a force approximately directly downward acts on the rod 13. Therefore, regardless of the pulling direction, The tensile force is steadily transmitted as the sliding force of the rod 13, and the lowering switch 11 can be operated at all times.

In addition, as shown in FIG. 4, the lower opening end of the guide hole 12 is
If the tapered surface 12d expands in diameter downward (the one shown has an arcuate cross section, but it may also have a linear shape),
When a tensile force is applied from an oblique direction, the cable 15 and the main body 7
Since there is no hooking part between the two and the sliding resistance is reduced, it becomes more preferable.

As is clear from the above, according to the present invention, irrespective of the direction of the tensile force of the cable 15, the tensile force is steadily transmitted as the sliding force of the rod 13, so that the refueling hose The lowering switch 11 can be reliably operated with a small force that does not require a force to bend the switch 4.

Therefore, since the lowering switch 11 can be operated without bending the refueling hose 4 as much as possible, the refueling nozzle 5 can be lowered without shaking, thereby preventing the refueling nozzle 5 from hitting the vehicle body. Moreover, it becomes easier for the operator to catch the refueling nozzle 5 as it comes down.

Therefore, the tensioning means does not necessarily have to be pulled vertically downward, resulting in an effect that the operability is extremely improved.

Further, since the rod 13 is housed in the main body 7, the sliding portion of the rod 13 is not exposed to the outside, so dust or water droplets from rain etc. may not adhere to the sliding portion of the rod 13. Since there are no errors, it is possible to prevent operational errors caused by this.

In addition, if the lower end of the cable 15 is made into an elastic rod-shaped grip, problems such as the rope becoming entangled with the refueling nozzle can be eliminated, and the impact when the grip hits the refueling nozzle can be alleviated. can.
