Contact network annular steel pipe column weld joint grinding equipment

Abstract

The invention discloses contact network annular steel pipe column weld joint grinding equipment. The contact network annular steel pipe column weld joint grinding equipment comprises two rails, a main machine linkage mechanism and a steel pipe column supporting mechanism comprising a large-end carrier roller mechanism and a small-end carrier roller mechanism which can enable a steel pipe column weld joint to be kept at the horizontal position; the main machine linkage mechanism comprises a base, a left-right walking mechanism, a vertical rack, two vertical linear guide rails I, a sliding block I, a power mechanism driving the sliding block I to ascend and descend along the vertical linear guide rails I, a base III fixed to the side face of the sliding block I, a grinding mechanism and a polishing mechanism; the grinding mechanism and the polishing mechanism can be mounted on the base III in an up-and-down fine adjustment and front-and-back fine adjustment manner; and a machine base I is fixed on a base IV in an inclination angle adjustable mode, a base V is fixed on the base III in a height fine-adjustment mode and in a front-back mode, and a machine base II is fixed on the base V in an inclination angle adjustable mode. According to the contact network annular steel pipe column weld joint grinding equipment, grinding and polishing are synchronously carried out, welding seams are automatically aligned, the production efficiency is high, the labor intensity of operators is small, safety is achieved, and the grinding and polishing quality is good.

Description

technical field [0001] The invention belongs to the field of manufacture of catenary ring steel pipe columns, and relates to a welding seam grinding equipment of catenary ring steel tube columns. Background technique [0002] At present, the steel plate is generally used as the material of the ring-shaped steel pipe column of the electrified railway catenary in my country, and the general processing and forming process of the main steel pipe is: bending machine bending → closing machine closing → automatic submerged arc welding machine welding → weld seam grinding, etc. After the welding is completed, there are one or two long longitudinal welds in the steel pipe column body, and there is a small amount of welding spatter around the welds. The longitudinal welds and their surroundings need to be ground and polished. The grinding method at this stage generally uses a trolley grinder to grind, and after the basic pass, use a trolley polisher to polish and repair the weld seam....

AI Technical Summary

Problems solved by technology

This kind of welding seam processing method firstly grinds, then polishes, the production efficiency is low, the operator is labor-intensive, and safety is not easy to guarantee. Manual positioning requires high technical level of the operator, and t
