2. Description of the Related Art It is common to cut a large forged material or a cast material by injecting a cutting flame toward a steel material using a cutting torch. By the way, when cutting a steel material by gas cutting, a large amount of harmful cutting fumes are generated from a cutting portion of the steel material and contaminate the environment. Therefore, equipment capable of properly processing the cutting fume is demanded.

[0003] Therefore, as shown in FIG. 5, a conventional gas cutting equipment is provided with a rail 1 on a support leg 1 in front of a cutting work place F1.
The torch truck 2 is placed on the rail 1a so as to be able to move horizontally in the longitudinal direction of the steel material W, and the horizontal arm 3 is horizontally mounted on the mounting arm 2a of the torch truck 2 in the width direction of the steel material W. The cutting torch 4 is attached downward so that the cutting torch 4 can be moved. On the other hand, a cutting grid 5 is provided with a tall grid base metal 5a, and a cutting flame 6 is applied to a steel material W on the base metal 5a. It has been general to cut the steel material W by moving the cutting torch 4 in the width direction of the steel material while spraying downward. That is, it was cut downward so that the slag was easily discharged. Further, a dust collecting hood 8 is disposed above the cutting work place F1, and the generated cutting fume 7 is collected and treated. Generally, cutting of the steel material is performed simultaneously at two places, for example, by cutting off the head and tail. In many cases, a dust collecting hood is provided in a range sufficiently covering the entire length of the steel material.

However, in the conventional gas cutting equipment, since the cutting torch 4 is mounted downward, the space for the cutting flame 6 to blow through under the steel material W in order to cut the steel material W. And the height of the base metal 5a of the cutting carriage 5 needs to be increased, and there is a problem that the handling property of the steel material is poor. Further, since most of the cutting sliver 9 is discharged downward and accumulates in the metal base 5a of the cutting trolley 5, the cleaning of the cutting slag 9 is very complicated. further,
As described above, the dust collection hood needs to be large enough to cover the entire length of the steel material, and cuts the steel material W at a high position downward, so that the cutting fume 7 can be spread over a wide area by the jetting force of the cutting flame. However, there is a problem that a large dust collecting hood 8 is required, and thus a dust collector having a large capacity is required. In view of the above problems, the present invention provides a gas cutting facility that can improve the handling of the material to be cut, simplify the cleaning of the cutting stick, and can process the cutting fume by a dust collector that is much smaller than before. That is the task.

Therefore, the gas cutting equipment according to the present invention comprises a cutting cart on which a material to be cut is placed horizontally,
A torch truck that can travel freely in parallel with the cutting cart is provided before the cutting cart at the cutting job site, and the cutting torch is placed on the workpiece via the lifting arm. A plurality of dust collection hoods are connected in the running direction of the cutting trolley above the cutting work place, and a damper is attached to each dust collection hood to collect dust for each dust collection hood. The gist of the present invention is to provide a cutting noro chamber that is configured so as to be integrated with each dust collecting hood, behind the position of the cutting cart in the cutting work place.

[Function] When the cutting flame is sprayed sideways from the cutting torch and the material to be cut is cut, the cutting slag is blown to the back of the cutting trolley and accumulates in the slag receiving chamber and does not accumulate much in the cutting trolley. The cleaning work of the cutting trolley is simple. Further, the slag in the slag receiving chamber can be easily processed by putting another container in the slag receiving chamber in advance and exchanging the container. Further, as the cutting base metal, short square members are simply arranged on a carriage like a sleeper at appropriate intervals, and the position of the material to be cut is reduced, and the handling property of the material to be cut is good. Further, the cutting fume is also blown straight into the back of the cutting cart, and is collected from the noro receiving chamber by only one specific dust collecting hood with a damper opened only there, so that the dust collecting efficiency is extremely high. In addition, since the cutting torch is moved in the vertical direction toward the side surface of the workpiece to be cut, the dust collecting hood can be made much lower than before. As a result, the cutting fume can be efficiently processed by a dust collector much smaller than before.

When cutting a long steel material W, the steel material W is placed laterally on a base 11 of a cutting cart 10 and the cutting cart 1 is cut.
0 is conveyed into the cutting work place F1, and at the same time, for example, two torch trucks 13 are respectively adjusted to two cutting positions, and only the damper 181 of the dust collecting hood 170 at that position is opened to cut. Most of the cutting slag 21 is blown away behind the cutting trolley 10 by the impact of the cutting flame 16 and accumulates in the slag receiving container 191. Can be very easy. Further, it is not necessary to make the base metal 11a so high, and the steel material W can be easily handled.

Also, in addition to the fact that the height of the base metal 11 can be reduced, the cutting direction is changed from the upper surface of the steel material to the side surface, that is, from vertical to horizontal. Since the dust collecting hood 17 is located at a lower position in front, the height of the dust collecting hood 17 is set to 5000
mm to 2500 mm, which is a half, and the production cost of the dust collection hood can be greatly reduced. Further, the dust collecting capacity of the dust collector is reduced to about 1/3 of the conventional one, and the installation cost and the operating cost of the dust collector can be reduced to about half.
