Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an oil supply device for loading oil onto a tank truck, for example.

2. Description of the Related Art Oil supply devices having loading arms have been used for loading oil onto tank trucks and tank wagons at oil refineries, oil depots, and the like.

In this conventional refueling system, a rack is installed at a refueling station, a riser pipe is projected upward from the rack, and a loading arm is connected to the riser pipe.
This loading arm was connected via a swivel joint so as to draw an arc in the horizontal plane around the riser pipe, and the tank truck was parked at a predetermined position close to this rack for refueling. .

Therefore, this conventional refueling system requires a rack that occupies a large area of the site, and because the loading arm moves in an arc around the riser pipe, a wide refueling area is required. Also, because the loading arm moved in an arc, refueling could only be done in a narrow area relatively close to the rack. Also, the piping of the loading arm was complicated.

In particular, tank trucks have their tanks divided into multiple chambers in the front and rear directions, and each chamber has a refueling port.
During refueling work, the drop pipe connected to the loading arm must be moved approximately linearly in the front and rear directions. However, since the loading arm moves in an arc, its operation is troublesome.

For example, Japanese Patent Publication No. 53-3087 discloses a technique in which pipe bodies connected by a plurality of swivel joints are vertically arranged to form a telescopic pipe in a suspended fuel station. However, this technique does not allow the use of a pipe with a relatively small diameter because the amount of refueling per unit time is relatively small at a refueling station such as a gasoline station where the refueling nozzle is suspended. Even if they are arranged vertically, there is no problem in terms of size and strength. However, in order to refuel lorries, there is a refueling depot that has a relatively large diameter pipe that extends vertically, such as a drop pipe, and is rotatably connected in a vertical plane for the purpose of moving the pipe in the vertical direction. In some cases, when sliding pipes are stacked vertically, their vertical dimensions increase, and therefore the supports must be made considerably taller, and the guide means of the swivel joint must be made considerably strong and strong in terms of strength. Must be.

Furthermore, Japanese Patent Application Laid-Open No. 52-1621 discloses a technique in which a drop pipe is rotatably pivoted in a vertical plane, but this known technique has a limited refueling range, and for example, each hatch of a lorry vehicle is This is inconvenient because the lorry vehicle must be moved when refueling the vehicles one after another.

Therefore, an object of the present invention is to make it possible to effectively utilize the site of a gas station, to move the drop pipe in a straight line above the lorry, and to support the pipe body relatively easily in terms of strength. To provide a refueling device that can be used without making the canopy unnecessarily high.

According to the refueling device of the present invention, an engaging member is provided on the upper surface of the pipe bodies that can mutually rotate in a horizontal plane, a guide member is provided above the pipe body, and the engaging member is engaged with the guide member. The end of the tube that guides the engaging member horizontally is provided with another tube that is rotatably connected to each other in a vertical plane, and a drop pipe is pivotally connected to the other tube.

Therefore, the guide member provided on the upper surface of the tube engages with the engagement member provided above and moves along the guide member, so that the tube provided with the engagement member is suspended from above. This ensures reliable support for relatively large diameter and heavy pipes. In addition, since there is a guide member above, the vertical dimension can be limited to a certain range regardless of the number of pivoted pipes, so even if a large lorry approaches below, the canopy will not be raised too high. There's no need to. In addition, another tube is provided at the end of the tube that guides in the horizontal direction,
The drop pipe is pivotally connected, and the heavy weight of these other pipe bodies and the drop pipe is supported by the engaging member that engages with the guide member, so the engaging member must be able to withstand the weight. If this is the case, there will be no problems with strength.

In carrying out the present invention, a horizontally extending groove can be used as the guide member, and a T-shaped member that engages with the groove can be used as the engaging member. If necessary, the T-shaped member may be provided with rollers to further facilitate its movement.

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