Movable welding fume dust collecting device

Abstract

The invention discloses a movable welding fume dust collecting device which comprises a workshop stand column, an exhaust fume collecting hood support and a telescopic exhaust fume collecting hood. Two horizontal cross beams in parallel are arranged between the workshop stand column and the exhaust fume collecting hood support; chain wheels are arranged at the front ends and the tail ends of the outer sides of the cross beams; a chain is connected between two chain wheels on the same cross beam; and the tail end of the telescopic exhaust fume collecting hood is fixed to the tail ends of the two cross beams, and the front end of the telescopic exhaust fume collecting hood is fixed onto the two chains, so that extension and compression are realized through the rotation of the chains. The exhaust fume collecting hood is convenient to stretch out and draw back, so that the welding environment pollution is low, and the space is further saved.

Description

Technical field [0001] The invention belongs to the technical field of welding fume dust removal, and in particular relates to a movable welding fume dust extraction device. Background technique [0002] In the prior art, the welding workstation mostly adopts a floor-standing robot welding method, which has a relatively complicated structure and a large area, especially in the process of moving the welding arm, which requires a large space to achieve. A large amount of welding fumes will be generated during the welding process, which causes serious pollution. , And it will endanger the health of workers. At present, the welding fume dust removal equipment is completed by connecting a dust collecting hood to the suction arm. However, the setting of the dust collecting hood greatly limits the working space of the welding workstation and affects the movement of the welding arm, thus restricting the welding work The completion. Summary of the invention [0003] In order to make up fo...

[0002] In the prior art, the welding workstation mostly adopts the floor-standing robot welding method, which has a relatively complex structure and occupies a large area, especially in the process of moving the welding arm. It needs a large space to realize it. During the welding process, a large amount of welding fumes will be generated, and the pollution is relatively serious. , and will endanger the health of workers. At present, the welding fume removal equipment is completed by connecting the suction arm with a dust collection hood, but the setting of the dust collection hood greatly limits the working space of the welding workstation, affects the movement of the welding arm and limits the welding work. the completion of
