The cantilever support 2 is a fixed base for installing the cantilever, and a driving motor 4, an induced draft fan 3 and other equipment are also required to be installed on the cantilever support.
The effect of draught fan 3 is: the air suction arm 11 absorbs the welding smoke dust into the main air pipeline through the induced draft fan 3.
The driving motor 4 is used for driving the driving arm gear 5 to control the driving arm 9 to rotate left and right by 180 degrees.
The rigid suspension 6 is used for reducing the stress condition of the driving arm 9 and the motor gear during the rotation process of the cantilever of the invention.
