Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a mobile vehicle that can run while carrying a gas cylinder that is heavy and difficult to handle.

(Prior art) Conventionally, the vehicle used to move cylinders within a factory, etc. is a hand-pushed unicycle, or in the case of multiple cylinders, a three- or four-wheeled vehicle that can be placed horizontally or propped up on an inclined plane. etc.

In particular, the present invention relates to patent no.
No. 57 (Special Publication No. 54-32598), No. 1.195
, No. 666 (Japanese Patent Publication No. 58-28480), this transfer vehicle is suitable for the standard gas filling and mixing method.

(Problems to be Solved by the Invention) In the conventional mobile vehicles mentioned above, cylinders were moved by being mounted horizontally or side by side in an inclined manner, so it was necessary to provide a sufficient width of movement passage within the factory. There were some drawbacks that shouldn't have happened. Furthermore, the mobile vehicle itself must be relatively large and require a large storage space. With the above installation, it was also difficult to transfer cylinders.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention is characterized in that the cylinders are mounted in an upright state, and therefore, in order to stabilize the upright cylinders, a device is used to hold the cylinders. It is made up of

(Embodiment) The embodiment shown in the figure is based on the implementation of the above-mentioned patent, and is a six-cylinder embodiment in which six cylinders can be mounted at the same time.

The picture frame-shaped frame body 1 can be mounted at positions a, b...f, but one position a will be explained and the other positions b, b, ... f will be explained.
...f has the same configuration. The frame body 1 has at least one wheel and two wheels 2.3 at the front and rear, and can be self-propelled by a drive source 4 and steered by the same wheel or other wheels.

A shaft 6 interlocking with a motor 5 communicates with the upper part of the upper frame of the frame 1, and a chain wheel 7 is attached to this shaft.

In addition, a hevel gear 8.9 is provided in a floating manner on the same shaft 10 in opposition to the lower part of the upper side, and meshes with both hevel gears 8.9, and a pinion gear bell 11 is supported by a bearing 12. It is connected to a chain wheel 13, and this chain wheel 13 interlocks with the chain wheel 7 described above via a chain wheel 14.

Arms 15.16 are respectively fixed to the bell gear 8.9 in the diametrical direction thereof, and these have handle rods 17.1.
8 extends toward the lower side of the frame 1, and a gripping member 19, 20 that surrounds approximately the circumference A of the bong B is provided at its tip. If necessary, a somewhat longer flexible piece 21, such as a spring material, may be attached to the end of the gripping member 19,20.

It is preferable that the lower side frame of the frame body 1 is provided with a non-slip member 22 that fits into the bottom recess of the bong B.

A processing vehicle T that performs mixing of standard gases using the mobile vehicle A of the present invention is illustrated in FIG. 7 and subsequent figures as an embodiment of the method disclosed in the patent. That is, a cart 31 that can move a predetermined distance on a rail 30 has bearings 32 and 33 at both end positions, and a rotating body 34 is rotatably supported by the bearings 32 and 33.・Position a' of the part corresponding to f...
- A housing portion for the cylinder B is formed at f', and since this structure is the same, only position a' will be explained.

A back plate 35 capable of stably accommodating the cylinder B, a bottom plate 36 for receiving the bottom of the cylinder at the lower part, and a hole 37 for receiving the neck of the cylinder B at the upper part are formed on the back side.

A gear 39 is attached to a shaft 38 provided on the rotating body 34 described above, and can be rotated by a drive section 40.

(Function) To load the cylinder B filled with mixed gas on the mobile vehicle A, the controller 23 is operated to rotate the motor 5 to connect the shaft 6, chain wheel 7, chain wheel 14, chain wheel 13, and pinion bevel. 11 to rotate both bevel gears 8.9. Then, since both bevel gears 8.9 rotate in opposite directions, approximately half of the circumference of the cylinder B is released from the grip member 19.20 by approximately 1/8 rotation of the circumference, and this release Load the cylinder B from the surface and hold the gripping member 19.2 again.
When the cylinder B is rotated 178 times in the opposite direction from 0, the cylinder B is stably fixed to the moving vehicle A at each position a...f.

The controller 23 starts and controls the drive source 4 to drive it to the moving location. For example, in the case of transferring to a processing vehicle T that mixes gases, either the front or rear surface of the moving vehicle A is positioned on the left side in FIG. Depending on the direction of rotation, the gripping member 19.20 can be opened on either the front or rear side. Upon opening, the motor 40 is rotated to rotate the shaft 38 via the gear 39. Then, the bottom plate 36 slightly lifts the cylinder B, causing the cylinder B to fall toward the processing vehicle T, and as the rotating body 34 tilts, the cylinders at positions a-f are transferred to positions a' to f'. As the inclination further advances, the neck of the cylinder B slides into the hole 37 and stabilizes. However, the processing vehicle T was moved to the rail 30.
The gas is mixed by running on top of the tank and creating a water bath at a substantially constant temperature using the method disclosed in the above-mentioned patent.

Note that it is also easily possible to perform gas injection work during the above-mentioned tilting.

(Effects of the Invention) By transporting cylinders in an upright position, the transport vehicle of the present invention reduces the width of the traveling path, making it easier to change direction, and the ability to utilize the falling action of the cylinders during reloading, etc., requires less labor. Furthermore, since the gripping member operates along the circumference of the cylinder, it is advantageous in terms of space, unlike a door or the like.
