Abstract

The invention relates to a gas shielding tool for the back of a gas shielded welding seam. The gas shielding tool comprises a movement mechanism, a connecting mechanism and a gas supply system which are sequentially connected, wherein the movement mechanism comprises a vehicle body, wheels arranged at the lower end of the vehicle body and a telescopic pull rod arranged on the side wall of the vehicle body; the connecting mechanism comprises a rocking bar A, a rocking bar B, a support frame, a spring and a guide rod, wherein the rocking bar A is hinged to the upper end of the vehicle body, the rocking bar B is hinged to the end of the rocking bar A, the support frame is arranged at the lower part of the rocking bar A, and the guide rod is inserted to and matched with the spring; and the gas supply system comprises a gas supply box fixedly arranged at the end of the rocking bar B and a gas supply pipeline connected with the gas supply box. The gas shielding tool has the advantages that most of parts of the gas shielding tool for the back of the gas shielded welding seam are detachable, so that the gas shielding tool is high in adaptability, convenient and flexible as well as simple in installation and operation; the gas supply box can be tightly fitted to a weldment to the greatest extent through being regulated by using jackscrews and a rocking bar mechanism and by virtue of a spring force, so that the shielding gas is saved, and the effect is favorable.

Description

technical field [0001] The invention relates to a gas protection tool, in particular to a gas protection tool for the back side of a gas shielded welding seam. Background technique [0002] In the process of welding stainless steel with gas shielded welding, in order to ensure the quality of the weld, it is necessary to keep the back side under the atmosphere of shielding gas during the first few passes of welding. Generally, one person is required to carry out gas protection on the back of the weld while holding a simple gas protection device. This method consumes manpower and does not achieve good results, especially when welding the circular seam of the cylinder, it is more difficult to operate and the work efficiency is reduced; Therefore be badly in need of developing a kind of gas protection frock that makes welding operation simple, processing quality good and efficient high, after searching, do not find identical or similar technical scheme with the present invention...
