Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a hose supporting device for a refueling vehicle, and in particular, a hose supporting device for a refueling vehicle which is arranged around a vehicle body with a gap and which can be moved up and down by a drive device. Regarding the device.

[Conventional technology]

BACKGROUND OF THE INVENTION Refueling vehicles, commonly called Hydland Servicers, are widely used to refuel aircraft. This is a special vehicle that connects an intake hose to a hydrland valve on the underground pipeline of an airport so that fuel oil can be supplied to the oil supply hole of the wing of the aircraft via the delivery hose. After the refueling is completed by such a Hydland servicer, the intake hose is removed from the Hydland valve, and the hose provided on the periphery of the vehicle body is hooked with the intake hose to move to another place. The work of hooking this intake hose to the hose hanger is not easy because the hose is long and heavy.Therefore, the applicant proposed a device that hydraulically drives the hose hanger to move up and down in order to hook the intake hose around the vehicle body. (See Japanese Utility Model Laid-Open No. 61-118898).

FIG. 3 shows a conventional hose support device for a refueling vehicle as described above. In the figure, reference numeral 21 indicates a hose hanger, and the hose hanger 21 is a column 22 standing vertically.
It is fixed to the side of. Above hose hanger 21 and support 22
Is the pin 2 in the long hole 24 of the tip 23a of the operating rod 23.
It is supported so that it can move up and down via 5.

In the figure, the solid line indicates the lowered position of the hose hanger 21, and the alternate long and short dash line indicates the raised position. The other end of the operation rod 23 is pivotally supported on the vehicle body 26 via a pivot 27. further,
The bracket 28 on the operating rod and the lower end of the link 29
The upper end of the link 29 is connected to the rotating arm 31 by a pin 32. The pivot arm 31 is pivotally attached to the pivot 33.

On the other hand, the column 22 is telescopically fitted in the guide tube 34. An angle-shaped hose retainer 35 is fixed to an intermediate position of the guide cylinder 34 by bending the tip downward. The hose retainer 35 cooperates with the hose hanger 21 to moor the intake hose 36 so as not to fall off the hanger 21.

[Problems to be solved by the device]

However, in the above-described refueling vehicle, there is a case in which a part of the intake hose 36 lifts the hose hanger 21 while being separated from the semicircular groove 21a formed in the hose hanger 21. When the hose hanger is raised in such a state, the hose 36 may be narrowed and crushed between the hose hanger 21 and the hose retainer 35 fixed to the guide tube 34 as shown in FIG. There is also a danger that fuel will leak if a part of the hose is damaged.

Therefore, an object of the present invention is to solve the above-mentioned problems with the conventional technology and to reliably hold the hose placed on the hanger when the hose supporting device is moved up and down. To provide.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention provides a hose support device comprising a column that can move up and down along a guide tube and a hose hanger that is fixed to a side surface of the column and has an upward groove. A hose retainer for mooring the intake hose in cooperation with the hose hanger is provided rotatably around the ear shaft on the side of the hose hanger.
It is characterized in that a push-up rod, which is loosely fitted in the sleeve and is movable up and down, is provided, and the upper surface of the push-up rod flips up the hose retainer at the lowered position of the hose support device.

[Action]

According to the present invention, the hose support device is composed of a pillar that can move up and down along the guide tube and a hose hanger that is fixed to the side surface of the pillar and has an upward groove, and the hose hanger is provided on the side surface of the pillar. A hose retainer for mooring the intake hose in cooperation with is provided rotatably around the ear shaft, and a push-up rod that is loosely fitted in the sleeve and is vertically movable is provided on a side surface of the hose hanger. When the hose support device is grounded, the hose retainer is flipped upward so that the hose can be taken out and stored freely. On the other hand, the hose retainer can be moored in cooperation with the hanger so that the hose does not drop when the hose support device is moved up and down.

〔Example〕

An embodiment of a hose supporting device for a refueling vehicle according to the present invention will be described below with reference to FIGS. 1 and 2. Reference numeral 1 in the figure
Shows the lower part of the column, and the column 1 is formed by using a square steel pipe or the like, and the upper end of the column 1 is telescopically fitted into the guide tube 2. A hose hanger 3 having a substantially L-shaped cross section is fixed to the side surface of the column 1.
Further, ear shafts 4 are provided on both sides of the support column 1 near the upper end of the mounting portion of the hose hanger 3. A hose retainer 5 is pivotally attached to the ear shaft 4 via a bearing 5a. The tip of the hose retainer 5 is bent in an angle so as to cover the hose hanger 3. The hose hanger 3 is integrally formed of a hose receiving portion 3a provided so as to project outward and a bracket portion 3b attached to a column.

A semicircular groove portion 3c is provided on the upper surface of the hose receiving portion 3a, and its radius is almost the same as that of the intake hose 6 to be placed, and the hose 6 can be housed in this groove portion 3c. . A sleeve 7 is fixed in the middle of the side surface of the bracket 3b so that its tube axis coincides with the vertical line. A push-up rod 8 is slidably fitted in the sleeve so that the tip of the push-up rod 8 abuts the hose retainer 5 when the push-up rod 8 is moved upward, and the hose retainer 5 is flipped up. It is like this. In this embodiment, two stopper pins 9, 9 are provided on the side of the push-up rod 8 so as to project. The upper and lower stopper pins 9 and 9 contact the upper end or the lower end of the sleeve 7 to adjust the vertical movement amount of the rod.

A ground plate 10 is fixed to the lower end of the push-up rod 8.

Since the present invention is constructed in this manner, when the hose support device is in the lowered position, the ground plate 10 at the lower end of the push-up rod 8 comes into contact with the ground surface as shown in FIG. There is. At this time, the push-up rod 8 is pushed up and its tip comes into contact with the hose retainer 5,
The hose retainer 5 is in a state of being flipped up.

That is, all hose supporting devices arranged around the vehicle body are grounded, and at the same time, the hose retainer 5 covering the hose hanger 3 is released, and the hose 6 can be taken out and stored.

As shown in FIG. 2, when the hose 6 is placed on the hose hanger 3 and is raised along the guide tube 2 of the lifting device, the push-up rod 8 descends in the sleeve 7 by its own weight and the push-up rod 8 is pushed up. The hose retainer 5 contacting the tip of the rod 8 starts to rotate downward. When the hose retainer 5 further rises, the hose retainer 5 comes into contact with the upper end of the bracket 3b to stop the rotation, and the push-up rod 8 separates from the hose retainer 5 and descends until the upper stop pin 9 comes into contact with the upper end of the sleeve 7.

Since the tip end of the hose retainer 5 which has stopped rotating is locked to the tip end of the hose receiving portion 3a, the hose hanger 3 can be always covered when the hose support device is in the ascending / descending state.

〔The invention's effect〕

As is apparent from the above invention, according to the present invention, the hose support device is composed of a column that can move up and down along the guide tube, and a hose hanger that is fixed to the side surface of the column and has an upward groove. A hose retainer for mooring the intake hose in cooperation with the hose hanger is provided on the side surface of the column so as to be rotatable around the ear shaft, and on the side surface of the hose hanger, a hose retainer is loosely fitted in a sleeve and can move up and down. A lifting rod is provided so that the upper surface of the lifting rod flips up the hose retainer at the lowered position of the hose support device, so that the hose is surely placed on the hanger when the hose support device is moved up and down. Therefore, the hose can be prevented from being crushed or damaged.
