Machine for welding border angle steel and connection sleeve of standard section of tower crane

Abstract

The invention relates to a machine for welding border angle steel and a connection sleeve of a standard section of a tower crane, which comprises a conveying mechanism, a carrying frame, a carrying mechanism, a rotary positioning device, a sleeve feed mechanism, a welding device, a finished product carrying mechanism and a finished product conveying mechanism, wherein the rotary positioning device comprises a support table, a rotary working table and a rotating device; the rotating device controls the rotation of the whole rotary working table; the rotary working table comprises an angle steel fixing table and a horizontal compression mechanism; the horizontal compression mechanism drives the angle steel fixing table to move in the Y direction to clamp the angle steel; the angle steel fixing table is provided with an angle steel angle positioning block for spacing the angle steel; and the rotary working table is also provided with an angle steel vertical compression mechanism for limiting the vertical movement of the angle steel. Thus, the machine is compact in structure and high in automation degree, can be used less artificially, reduces the material conveying delay time and the labor intensity in the carrying process, improves the processing quality, greatly improves the working efficiency, shortens the processing cycle, lowers the production cost and greatly reduces the labor intensity.

Problems solved by technology

[0003] As one of the four pillar industries of the national economy, the real estate industry is widely used in the construction of new buildings. However, at present, most of the processing of the standard section of the tower crane is mainly manual welding, and the production efficiency is extremely low. , each person can only weld 4-5 standard sections per day, especially the welding surface quality of the angle steel and the sleeve of the standard section frame is unstable, resulting in the welded standard section. After arriving at the construction site, splicing is difficult and the tower crane gap If it is too large, it is easy to cause the accident of tower crane toppling

For individual large-scale tower crane manufacturers, the welding process of angle steel and sleeve is welded by imported robots, which can only weld standard joint angle steel with a single piece and single head, and manual handling and operation are still required for feeding and sleeve penetration. , although the quality of the welding surface is high, the price of the robot is extremely expensive, and the equipment investment is large. At the same time, the angle steel and the sleeve need a pre-welding process before using the welding robot, and then the pre-welded workpiece is manually transported to the welding machine part of the welding robot , the manual labor intensity is extremely high. At the same time, with the continuous rise of labor costs in recent years, enterprises are also under tremendous economic pressure. There is an urgent need for an automated equipment that can replace manual handling and welding.
