Abstract
The invention discloses a production line automatic welding method for the main chord of a standard section of a tower crane. Planting trolley A, first storage station, second transplanting trolley A, inner and outer sealing plate spot welding station, second storage station, connection sleeve spot welding station, third transplanting trolley A, third storage station, alignment Device, transplanting trolley B, positioning sleeve welding station, dust removal room and repair welding station. Through the processes of loading and feeding, sawing and cutting, rotary feeding, pushing and turning, drying, spot welding of inner and outer sealing plates, spot welding of connecting sleeves, welding of positioning sleeves, and repair welding, the main chord of the tower crane standard section is fully automatic. Welding has the advantages of low cost, simple and reliable structure, and low energy consumption.
Description
technical field [0001] The invention relates to the field of welding technology and equipment, in particular to an automatic welding device and method for a standard section main chord of a tower crane. Background technique [0002] Tower cranes for construction are mainly composed of standard sections, consoles, cantilever beams, and counterweights. Among them, the standard section is the most important part of the vertical support tower crane. The processing quality of the tower crane standard section is an important link related to the safety of the tower crane. According to my country's hoisting machinery supervision and inspection regulations, the routine tower crane inspection procedure is to review the acceptance records of concealed projects such as foundations and tracks. In the inspection, the first thing to pay attention to is whether the quality of the standard section of the tower crane meets the manufacturer's design requirements. The standard section of the ...
