Short steel pipe outer wall polishing device for building engineering

Abstract

The invention discloses a short steel pipe outer wall polishing device for building engineering. The short steel pipe outer wall polishing device comprises a bottom base plate, a supporting rod frameis arranged on the upper end face of the bottom base plate, the upper ends of four connecting rods and the lower sides of four corresponding arc-shaped jacking plates are hinged, the left end of an adjusting transverse shaft penetrates out of a supporting transverse pipe, and a rotating transverse lead screw is provided with a driving spiral sleeve matched with the rotating transverse lead screw;the outer side wall of the driving spiral sleeve is provided with a connecting sleeve, and the upper side of the supporting rod frame is provided with a hydraulic cylinder, wherein the bottom of the hydraulic cylinder is slidably connected with the supporting rod frame; the side end of the supporting rod frame is provided with a double-output-shaft motor, one end of the double-output-shaft motor is connected with the outer side wall of the supporting transverse pipe through a transmission mechanism, and the other end of the double-output-shaft motor is provided with an incomplete bevel gear; and one end of the rotating transverse lead screw is provided with two rotating bevel gears, and the two rotating bevel gears are engaged with the incomplete bevel gear alternately. The short steel pipe outer wall polishing device is simple in structure and convenient to operate, a steel pipe is fixed stably, the polishing effect is obvious, the efficiency is high, and the short steel pipe outer wall polishing device is worth popularizing.

Description

technical field [0001] The invention relates to the technical field of steel pipe grinding, in particular to a grinding device for the outer wall of a short steel pipe used in construction engineering. Background technique [0002] After the steel pipe is formed, in order to improve the production and processing quality of the steel pipe, ensure the performance of the steel pipe, and beautify the appearance of the steel pipe, the steel pipe needs to be polished to remove burrs and rust on the surface of the steel pipe. Existing grinding equipment for steel pipes usually includes a processing table and a grinding wheel. During work, the steel pipe is fixed on the processing table, and the steel pipe is polished by the rotation of the grinding wheel and the friction between the outer circumference of the grinding wheel and the surface of the steel pipe. However, since the steel pipe has a cylindrical structure and its surface is a curved surface, the grinding wheel can only be...

AI Technical Summary

Problems solved by technology

However, since the steel pipe has a cylindrical structure and its surface is a curved surface, the grinding wheel can only be in contact with a part of the steel pipe when grinding, so that the steel pipe needs to be flipped and the steel pipe needs to be moved to achieve full grinding of the steel pipe. But in this way, the steel pipe is fixed unstable, and it is easy to separate from the grinding wheel, so that the processing efficiency is low and the grinding effect is poor.
