Abstract

The utility model relates to a lifting telescopic suction arm structure. The liftable telescopic suction arm structure comprises a supporting seat, a first supporting beam, a second supporting beam, a mounting seat and a dust suction pipe. One end of the first supporting beam is rotatably arranged on the supporting frame. One end of the second supporting beam is rotationally connected with one end of the first supporting beam far away from the supporting frame. The rotating shaft at the joint between the first supporting beam and the supporting frame is parallel to the rotating shaft at the joint between the second supporting beam and the first supporting beam. The mounting seat is arranged at one end of the second supporting beam far away from the first supporting beam. The suction pipe is configured to be retractable along a length direction thereof. The second support beam is configured to drive the mounting seat to lift. The lifting telescopic suction arm structure can be flexibly applied to various welding occasions such as large-scale workpiece welding, small-scale workpiece welding, multi-welding-spot welding and the like, and the dust suction pipe can reach a position closer to the welding spot to capture welding smoke, so that a better welding smoke capturing effect can be achieved even if smaller suction amount is adopted.
