A connector 7 is provided, is connected to another vehicle body 1, and is towed by a starter vehicle including a diesel engine or the like. Such a car body 1 receives the discharged slag in a slag ladle 2 in the vicinity of a converter or a smelting furnace, and is pulled to a slag yard to tilt the slag ladle 2 to discharge the slag. However, it is used to treat slag.

[0003] Similar track trucks include a mixed pig truck for transporting hot metal, a pot truck for transporting hot metal and molten steel, a slab truck for transporting slabs, a slag pot truck for treating slag, a rolling cart for rolls and chocks. Widely used as a product coil carrier. In addition to steel mills, rail cars are often used in factories and construction sites where heavy objects need to be transported.

In recent years, for example, Japanese Utility Model Laid-Open No. 60-182286.
As disclosed in Japanese Unexamined Patent Publication (Kokai), a trailer-type trackless bogie having a dump function is also used for transporting slag. For example, a trailer having a loading capacity of about 50T and having a dumping function is used for a steel mill premises.

[0005]

As described above, although various track trucks are used in the premises of steel mills, trackless trucks such as trailers can also be used to transport product coils, shaped steel and steel plates, and scrap. Widely used for transporting other general equipment and equipment parts. In one steel mill premises,
When both types of logistics, track-guided trucks and track-free trucks, are operated in parallel, both types of logistics are mixed in an environment where the operating rate of blast furnaces is decreasing due to production adjustments. And is extremely inefficient.

On the other hand, the transportation of molten pig iron, molten steel, slabs, slag, etc. is a place where high-temperature slabs or metal are dropped or deposited on the road surface, such as under a furnace such as a converter.
In a trackless truck that travels on a general road such as a trailer, soft wheels such as rubber tires are damaged and cannot run.

An object of the present invention is to provide a track-free carrier that can travel on a general road surface by wheels equipped with tires and can also travel on a road surface where the tires are easily damaged.

[0008]

1 and 2 show the construction of a trackless carrier truck according to an embodiment of the present invention. 1 is a front view and FIG. 2 is a plan view. At the center of the vehicle body 11, a slag ladle 12 capable of charging slag of about 30T is mounted. The slag ladle 12 has an elliptical shape whose major axis is the traveling direction of the vehicle body 1. Tires 13, which are soft wheels, are provided below the vehicle body 1. Outside the tire 13, side rollers 14 that are hard wheels are provided. The side roller 14 is formed of a hard metal material such as steel, and has a harder surface than the rubber tire 13. One side of the slag ladle 12 is tiltably supported with respect to the vehicle body 11 by a tilting shaft 15 that is pin-connected to the vehicle body 11. The other side of the slag ladle 12 is supported by a supporting device 16. Couplers 17a and 17b are provided on both sides of the vehicle body 11 in the traveling direction, and by joining the couplers 17b and 17a of the other vehicle bodies, respectively, a plurality of vehicle bodies 11 can be connected to travel. The circumference of the tire 13 is covered with a cover 18 to prevent damage to the tire 13 due to high temperature slag, metal pieces, and the like coming in. The trackless carrier according to the present embodiment generally has a tire 1
3 drives on a road surface 19 such as an ordinary road.

3 and 4, a plurality of vehicle bodies 11 are connected, a starter vehicle 20 pulls and travels on a road surface 19, and a tilting device 25 can discharge a slag 21 which is the content of the slag ladle 12. Shows the configuration. 3 is a front view and FIG. 4 is a simplified side sectional view. The tilting device 25 has a frame 26 that is suspended above the vehicle body 11, and pays out the wire 28 from a winding device 27 that is provided above the frame 26. The wire 28 lifts the supporting device 16 side of the slag ladle 12 through a fixed pulley 29 and a moving pulley 30. When the wire 28 is wound up by the winding device 27, the slag ladle 12 is largely tilted about the tilting shaft 15 as shown by the phantom line in FIG.
The slag 21 can be widely opened to the side and discharged quickly. During this tilting, the slag ladle 12 is placed on the outside of the vehicle body 11.
Since the center of gravity of the vehicle moves, it is preferable to provide a cradle 31 for receiving the side rollers 14 and the like so as to prevent the vehicle body 11 from overturning. In this case, the grounding of the pedestal 31 to the side rollers 14 and the grounding of the tire 13 to the road surface 19 are performed almost at the same time.

5 and 6 show a state in which the slag of the converter is put into the trackless carrier vehicle shown in FIG. 5 is a front view and FIG. 6 is a side sectional view. Under the furnace of the converter 35, high-temperature slag and slab pieces are scattered, and the road surface condition is severe for the tire 13. Therefore, the road surface 36 under the furnace is deeper than the normal road surface 19. In the portion of the furnace lower road surface 36, the side roller 14 is received from both sides of the vehicle body 11 by the side roller ground surface 37 installed as a partial track.
The tire 13 is adapted to be lifted by d from the road surface 36 below the furnace. A cover 38 is provided above the side roller ground surface 37 so that slag or the like does not fall from the converter 35 and accumulate on the side roller ground surface 37.

When the vehicle body 11 travels on such a furnace lower road surface 36, the starter vehicle 20 is temporarily retracted while each vehicle body 1 is moved.
1 may be passed under the converter 35 so that the slag is received by the slag ladle 12 while advancing one unit at a time. In this way, the starter vehicle 20 itself does not have to travel below the converter 35, and the starter vehicle 20 need only have soft wheels fitted with tires. As such a starting vehicle 20,
For example, it is possible to use a vehicle equivalent to a starter vehicle used for carrying luggage of an aircraft at an airfield or the like.

FIG. 7 shows another embodiment of the present invention in which the slab 40 is directly mounted on the vehicle body 11 and transported.
In this way, when carrying a heavy solid, the slag ladle 12 can be removed and a heavier load can be carried by the amount of the slag ladle 12. Also, if other types of pans are attached, not only the above-mentioned slag but also molten steel, hot metal, etc. can be easily transported.

Further, as in each of the above-described embodiments, the hot metal and the slab, which were conventionally transported by the railcar, can be transported by the railless truck, so that the transportation route can be easily changed or added, and the distribution is flexible. Can have Further, by making the connection method with the starting vehicle 20 for towing common, it becomes possible to perform the towing of various trackless carrier vehicles in combination with any starting vehicle, and the operating rates of the starting vehicle and its driver. Can be raised. Further, since it is not necessary to perform maintenance on both the dedicated track and the general traveling path, and maintenance can be concentrated on the general traveling path only, it is possible to reduce overall repair cost.

Further, in the above embodiment, the trackless carrier itself is not provided with a drive unit for traveling but is pulled by the starter vehicle. However, a drive unit is provided to make it self-propelled, and further others. If the trackless carrier trucks can be connected and towed, more flexible and efficient physical distribution can be achieved.

[0019]

As described above, according to the present invention, a soft wheel runs on a road surface such as an ordinary road, and a soft wheel is supported on a road surface where the soft wheel is easily damaged, and the soft wheel is floated from the road surface. Since the vehicle can travel, it can be freely traveled except for a specific place, and the physical distribution can be performed efficiently.

Further, according to the present invention, by supporting the hard wheels from the outside of the vehicle body, the soft wheels can be easily floated from the road surface. Therefore, even in a place where traveling is difficult or impossible with only the soft wheels, it is easy. You can drive,
Logistics can be made efficient.

Further, according to the present invention, since the container mounted on the vehicle body can be largely tilted to efficiently discharge the contents, the operation rate of the trackless guided vehicle is improved and it is used for many purposes. be able to.
