The side plate feeding mechanism for steel structure welding according to claim 3, characterized in that: the telescopic mechanism comprises a spiral boss (235) arranged on the overturning bracket (20) along the circumferential direction of a hinge shaft of the swinging bracket (231) and a pin rod (234) arranged on the hinge shaft of the swinging bracket (231), the hinge shaft of the swinging bracket (231) is in sliding connection with the overturning bracket (20) along the axis direction of the hinge shaft, the pin rod (234) is in sliding butt joint with the spiral boss (235), a first elastic unit (233) is arranged between the swinging bracket (231) and the overturning bracket (20), and when the swinging bracket (231) moves from the station a to the station b, the elastic force of the first elastic unit (233) can drive the swinging bracket (231) to slide towards the direction close to the first guide roller (21) along the axis direction of the hinge shaft; when the swing bracket (231) moves from the station b to the station a, the spiral boss (235) can push the pin rod (234) so as to enable the swing bracket (231) to slide in a direction away from the first guide roller (21) along the axial direction of the hinged shaft of the swing bracket.
5. The side plate feeding mechanism for steel structure welding according to claim 1, characterized in that: the base (31) is provided with a driving element for driving the overturning bracket (20) to overturn.
6. The side plate feeding mechanism for steel structure welding according to claim 5, characterized in that: the driving element is a piston cylinder, a cylinder body of the piston cylinder is hinged to the base (31), a piston rod of the piston cylinder is hinged to the overturning support (20) relatively, and a hinged shaft is not coaxial with a hinged shaft between the overturning support (20) and the base (31).
7. The utility model provides a steel constructs device of assembling in advance which characterized in that: the side plate feeding mechanism for steel structure welding comprises any one of claims 1 to 6.
