Description

Gas cutting apparatus for cylinder type container with multi function}

The present invention relates to a multi-functional gas cutting device of a cylindrical container to facilitate the cutting operation of a cylindrical container made of a large steel pipe, and more particularly, a marking work or a jig for cutting before cutting a cylindrical container. This eliminates the need for the operator to be close to the job site where high heat is generated and precisely cuts the root face and the bevel angle of the cylindrical container continuously, while mounting on the circumferential surface of the cylindrical container. Round and square flanges are also gas cut continuously to smoothly cut gas in cylindrical containers, and in particular, when vertical and horizontal movement of gas stoves and vertical gaps are adjusted through vertical and horizontal moving members. Positioning is done automatically and precisely and quickly, making the whole device smooth and easy to use. A multifunctional gas cutting device of a cylindrical container to be able to.

Generally, as shown in FIG. 1, the cylindrical container is mounted and fixed in a manhole 100 for water supply and drainage and an internal inspection, and is generated during welding such as seams in order to obtain full penetration during such a welding operation. The cut is divided into a root surface (C) to be infused by a high heat welding input heat and an improved angle cutting portion (C ') for cutting the edge at a predetermined angle to enable welding therewith.

The conventional gas cutter 200 used to gas cut such a seam and an improved angle cut is shown in FIG.

That is, as shown in Figure 2, after marking the cutting point of the cylindrical container to be cut, by igniting the manual cutting torch 210 supplied with oxygen and LP gas as an igniter to start the cutting operation by oxidizing the cutting point. In this case, the operator follows the cutting portion marked by using the driving wheel 220 installed in the manual cutting torch 210 to perform the cutting operation.

However, in the gas cutting operation of the cylindrical container by the conventional gas cutting torch 210 as described above, although not shown in detail in the drawing, the operator performs the cutting operation while holding the gas cutting torch 210 by hand. Due to this, due to the cutting flame and flying dross (dross), there is a problem that often occurs safety accidents such as burns when performing the operation inside the cylindrical container.

In addition, when the circumferential surface cutting operation of the cylindrical container 100 is performed by manually moving the driving wheel 220 while cutting, the cut drag line is not uniform and rough, so that additional finishing work of the cutting portion is performed. In the end, the cutting operation of the cylindrical container is delayed, and there are various problems, such as the post-welding operation cannot be performed precisely due to the poor cutting of each cutting surface.

The present invention has been made in order to improve the various conventional problems as described above, the object of which is, there is no need for a separate marking or jig for the gas cutting operation on the cutting portion of the cylindrical container, the operator on the job site where high heat is generated It is possible to continuously cut the root surface and the angle of improvement of the cylindrical container precisely without having to be located close to it.At the same time, the circular and rectangular flange portions mounted on the circumferential surface of the cylindrical container are also continuously cut so that the gas cutting operation of the cylindrical container is performed. While making the process extremely smooth, in particular, the vertical and horizontal movements of the gas torch and the position adjustment such as the adjustment of the gap with the container are automatically and precisely and quickly performed through the vertical and horizontal moving members to smooth the operation of the device as a whole. Multifunctional gas cutting device of cylindrical container is provided for easy use. It is in the ball.

As shown in FIG.

On the other hand, as shown in Figures 3 and 5, the hydraulic jacks 22 are horizontally integrally welded to the end of the cross-shaped fixed arm (22a), the upper of the cross-shaped fixed arm (22a) is a rectangular iron plate The base 20 is coupled, and the hydraulic pump 24 installed on one side on the base 20 and the distribution valve 26 connected thereto are connected to the hydraulic jack 22 as connecting pipes 28, respectively.

As a result, when driving the drive motor (24a) installed in the hydraulic pump 24, the hydraulic pressure of a constant pressure generated when the hydraulic pump 24 is operated through the distribution valve 26 and the connecting pipe 28 the hydraulic jack The ends of the moving rod 22b of the hydraulic jack 22 are press-fitted at four points before and after the inner circumferential surface of the cylindrical container 10 and at the left and right sides thereof, so that the base 20 is cylindrical. At any point in 10) the worker is positioned horizontally at the desired position.

In addition, as shown in Figures 3, 5 and 6, the worm shaft 36 is rolled out so as to be driveable in the inner lower side of the gear box 32 installed in the upper center of the base 20, The worm shaft 36 and the lower circumferential surface of the first vertical shaft 30, which is connected to the first driving motor 36a via a coupling and is vertically inserted through the gear box 32 and driven as a bearing, are connected to each other.
