By providing a welding auxiliary apparatus comprising a; gas discharge pipe to form a.

Hereinafter, the present invention will be described in more detail with reference to the drawings. As shown in FIG. 1, the welding auxiliary apparatus 1 of the present invention has a first arm 10 connected to the conduit 5 of the dust collector so as to rotate in a horizontal direction. As shown in cross section in FIG. 2, the upper end is connected to the conduit 5 through a bearing 15 so as to be rotatable in a horizontal direction, and has a hollow structure to communicate with the conduit 5. An internal flow path is formed. The first arm 10 has an upper end fixed to the outer race 15a of the bearing 15, and the conduit 5 of the dust collector is fixedly connected to the inner race 15b of the bearing member 15. The first arm 10 is rotatable in a horizontal direction with respect to the conduit 5 via a bearing 15.

In addition, unlike the hollow structure of the first arm 10, the second arm 20, which is connected to the other end of the first arm 10 through a hinge 17, is connected to the upper end and is movable up and down. It has a steel structure, the lower surface has a structure in which the rod 22 of the power cylinder 21 mounted on the first arm 10 is rotatably connected. The power cylinder 21 has a structure in which the rod 22 can be drawn out and drawn out by a power source. When the rod 22 is drawn out from the cylinder 21, the second arm 20 is formed of a first arm ( 10) coaxially elongated, the second arm may be raised upwards, but when the rod 22 is inserted into the cylinder 21, the second arm 20 with respect to the first arm 10; This descending and bent structure will be obtained. And, the power cylinder 21 has a configuration in which the rod 22 is automatically remotely controlled by the operator to achieve the vertical operation.

In addition, the third arm 30 connected to the lower end of the second arm 20 through a vertical hinge 27 and rotatable from side to side is provided with a support 32 having an enlarged size at the lower end thereof, and welding device 100. As it is equipped with a variety of welding apparatus can be mounted according to the use.

In addition, the power supply and the gas piping unit 40 for supplying power and air and various shielding gases to the welding device 100 are each of a plurality of power cables 110 and pipes 120 of a flexible structure. The power cable 110 and the pipes 120 extend along the first, second and third arms 10, 20, 30 and have a binder 42 on the arms 10, 20, 30. It is fastened to the arm 10, 20, 30 are integrally fixed to the joints of the arms 10, 20, 30. And the joints of the arms 10, 20, 30 of the arms 10, 20, 30 The bent portions 45 are formed to be smoothly moved together as the position moves, respectively. Utilities that can be supplied to the welding apparatus 100 through the power and gas pipe 40 may be CO2 gas, AC power, air, argon gas and all other gases required for welding, which is the resttable It can vary depending on the characteristics of the welder mounted on (32).

On the other hand, having a gas discharge pipe 50 for discharging the harmful gas generated by the welding device 100 to the outside, the gas discharge pipe 50 can be rotated at the upper end of the lower end of the first arm (10) It is made of a flexible tube 52 is connected so as to, the flexible tube 52 is equipped with a plurality of bent portion 54 is easy to adjust the position by the operator, the lower end of the tube 52, the hood 56 ) And the tube 52 forms a flow path connecting the inner flow path of the first arm 10 and the conduit 5 of the dust collector from the hood 56. The flexible tube 52 is rotatably mounted to the first arm 10, which is fixed to the center of the gas inlet 10a of the first arm 10 as shown in FIG. 3. The central ring 55 of the flexible tube 52 is rotatably inserted to form a rotating structure of the flexible tube 52.

On the other hand, a damper 60 for opening and closing the flow path of the tube 52 is mounted inside the hood 56, and the damper 60 has a side handle 62 by an operator as shown in FIG. 4. By opening and closing, the opening and closing is easily performed, and the harmful gas generated during welding by the suction pressure generated by the dust collector and delivered to the hood 56 is discharged to the dust collector side with the opening of the damper 60.

Reference numeral 70 denotes a CO2 gas welding torch, 72 denotes an arc welding holder, and 74 denotes a power outlet.

Welding aid device (1) of the present invention configured as described above when the operator drags or pushes the welding device 100 for the welding operation, the first arm 10 to move the welding device 100 horizontally The third arm 30 moves the welding device 100 left and right with respect to the second arm 20. When the welding device 100 is to be positioned at a predetermined height, the welding device 100 is displaced by displacing the position of the second arm 20 with respect to the first arm 10 using the power cylinder 21. ), The operator can freely position the welding device 100 to a position convenient for welding operation.

On the other hand, when the welding apparatus 100 is properly moved as described above, and the welding operation is to be performed, when noxious gas is generated by the welding operation, the operator pulls the hood 56 of the tube 52 to close the arrangement. Then, the damper 60 is opened to suck and discharge harmful gas through the hood 56. This harmful gas flows into the conduit 5 of the dust collector through the internal flow path of the flexible tube 52 and the hollow flow path of the first arm 10, and does not pollute the surroundings of the worker. In addition, since the flexible tube 52 is provided with a plurality of bent portions 54 in this process, even if the worker pulls or pushes the hood 56, the position can be freely adjusted in any direction. The hood 56 can be positioned without any burden to minimize the damage caused by harmful gases.

On the other hand, although the first arm 10 has a structure that is rotatably mounted to the conduit 5 of the dust collector, when the first arm 10 is used without a fixed dust collector, a mobile dust collector is used. , The welding auxiliary apparatus 1 of the present invention can have a movable structure. And, if the arrangement of the first, second and third arms (10, 20, 30) is arranged vertically rather than horizontally, and the welding device 100 is mounted by appropriately improving the structure of the resttable, High place welding can be done easily.

According to the present invention as described above, the cable 110 and the hose 120, etc. of the welding apparatus 100 is mounted along one of the first, second and third arms 10, 20, 30, and exhausted. By integrating the device to the first arm 10 so as to be free to move, the position can be easily adjusted to achieve effective discharge of harmful substances, thereby preventing the safety accident of the operator and simplifying the movement of cables and hoses. It is very effective to prepare the welding work. And, by having a structure that can adjust the height of the welding device 100, it is convenient to use in aerial work, etc., and therefore, the welding workability is greatly improved.
