Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame structure of, for example, a ladle carrying trailer. In particular, a trailer frame for efficiently loading and unloading cylindrical tall cargo that is a liquid container that cannot be laid down like a ladle that contains molten slag, molten aluminum, molten pig iron, etc. using a vehicle. Regarding the structure.

[0002]

2. Description of the Related Art As a conventional technique, for example, the method shown in FIGS. FIG. 3 shows the trailer 2. The frame 3 is arranged so as to form a flat floor surface 4. 1 indicates a tractor. Reference numeral 6 indicates a cargo such as a ladle to be loaded. Reference numeral 7 denotes a holding means provided on the floor surface 4 as a measure for preventing the cargo 6 from slipping.

FIGS. 4 and 5 show a ladle carrying device having a laterally adjustable ladle disclosed in Japanese Patent Laid-Open No. 5-507248. In FIG. 4, in the ladle carrying vehicle, the tractor 1 and the trailer 2 are engaged with each other by a pin 32.

The trailer 2 is formed of a U-shaped frame 26 and a gooseneck member 29 integrally formed with the U-shaped frame 26. An end of a cradle arm 27 is pivotally attached to the U-shaped frame 26 by a pin 30.
Further, both ends of the cylinder 31 are pivotally attached to the U-shaped frame 26 and the cradle arm 27. A mounting portion 33 on which the trunnion 28 of the ladle 12 is mounted is provided at the other end of the cradle arm 27.

By the expansion and contraction of the cylinder 31, the cradle arm 27 is swung with respect to the pin 30, and the ladle 12 is moved.
Is raised and lowered to load and unload the ladle 12 (not shown) from the stand. In FIG. 5, reference numeral 25 denotes a shift device for laterally moving the cradle arm 27 for adjusting the loading / unloading position of the ladle 12.

[0006]

The conventional means shown in FIG. 3 and the prior art shown in FIG. 4 have the following inconveniences, and countermeasures against them have been required.

That is, in the conventional means shown in FIG. 3, since there is a frame on the lower side of the ladle, the automatic trolley cannot enter the lower side of the ladle to carry out the loading and unloading work of the ladle. Needed cargo handling work with a forklift. For this reason, the cargo handling work could not be automated, and the driver / worker had to be placed in a high heat and dust environment.

Further, in the system shown in FIG. 4, since the frame is U-shaped and the opening is directed toward the rear of the vehicle, it is possible to carry out the loading and unloading work of the ladle by the automatic cart or the like only from the rear part. Also, because it is supported by the trunnion, for example, when ladle is transferred from another place by a crane to the main frame, it can be loaded and unloaded before it can be handled. There wasn't. For this reason, a space for a ladle stand is required, and the work in a narrow space has been made smaller.

[0009] Therefore, an object of the present invention is to provide a ladle carrying vehicle having a frame structure capable of loading and unloading ladles by any loading and unloading means such as an automatic carriage, a forklift and a crane. is there.

[0010]

DISCLOSURE OF THE INVENTION The present invention is a liquid material container transporting trailer connected to a tractor for loading a container for containing a liquid material therein, wherein a frame constituting the trailer is provided on one side with respect to an axle line of an axle. The other is a frame structure of a trailer for transporting a liquid material storage container, characterized in that it is formed as a substantially C-shaped opening for loading and unloading the liquid material storage container.

[0011]

By constructing the frame of the trailer for transporting the liquid material container as described above, the opening for allowing the ladle to be laterally carried in and out of the ladle carrier vehicle is secured.

[0012]

1 shows a plan view of an embodiment of the present invention. The trailer 2 engaged with the tractor 1 at the connecting portion 10 and towed has a ladle 12 mounted on a pair of support stands 11-1 and 11-2 arranged on the frame 3.
The frame 3 of the trailer 2 is arranged only on one side with respect to the axle axis, and is formed as a C-shaped structure with one side open so as to hold the ladle 12, and from this opening 19 side,
That is, the ladle 12 is loaded and unloaded from the side of the vehicle. 5 shows a rear wheel.

Reference numeral 13 is a member for integrally connecting the front and rear members on which the support stands 11-1 and 11-2 are arranged in the frame 3. Reference numeral 14 denotes a removable gate rod provided in the opening 19 for preventing the ladle 12 from falling. Two
Reference numeral 3 denotes a lid attaching / detaching means, and the arm 20 having a lid 24 arranged at the tip thereof is driven by the turning means 21.

FIG. 2 shows a side view of an embodiment of the present invention.
Reference numeral 16 denotes a push-up device mounted on an automatic carriage 15 arranged so as to travel at a position lower than that of the trailer 2, and the loading / unloading work of the ladle 12 is performed while adjusting the height thereof. .

In FIG. 2, the receiving seat 18 provided on the hanging member 17 of the ladle 12 is the supporting stands 11-1, 11-.
The ladle is placed on the frame 3 by being mounted on the frame 2. Reference numeral 21 denotes a swiveling means that constitutes the lid attaching / detaching means 23. Reference numeral 22 denotes an elevating means for attaching and detaching the lid 24 to and from the ladle 12 by elevating and lowering the arm 20.

[0016]

By constructing the present invention as described above, it is possible to carry out and carry in laterally without raising the ladle high, so that a wide range of cargo handling equipment can be selected. Since the ladle can be moved laterally, it can be automated by using an automatic cart. Space is saved as there is no need for a stand for the ladle. In addition, the ladle can be placed lower due to the thickness of the trailer carrier frame, and it is possible to prevent it from falling during transport on the trailer. And so on.
