AI Technical Summary

Technical Problem

Existing polishing machines for straight pipe processing require manual loading and unloading, which is time-consuming and labor-intensive. Furthermore, the dust and exhaust gas generated during the polishing process directly enter the operating room, affecting processing efficiency and environmental quality.

Method used

A polishing bed for processing large-diameter straight pipes with automatic loading and unloading was designed. It includes a loading and unloading structure, a polishing structure, and a dust and exhaust gas treatment structure. Automatic loading and unloading is achieved by using a hydraulic cylinder and a motor drive, and exhaust gas is treated by a bag filter and an activated carbon mesh.

Benefits of technology

It enables automatic loading and unloading of large-diameter straight pipes, reduces manual labor, improves processing efficiency, and effectively treats dust and exhaust gas, thus improving the quality of the operating environment.

Abstract

This utility model discloses a polishing bed for automatically loading and unloading large-diameter straight pipes, including an loading and unloading structure, a polishing structure slidably connected to the loading and unloading structure, and a dust and exhaust gas treatment structure fixed to the polishing structure. The loading and unloading structure includes a polishing box, and the position of the loading and unloading assembly inside the polishing box is adjusted by a telescopic structure. A first support plate is fixed on the polishing box, and a motor drives guide rollers to rotate on the first support plate. A limit guide plate is set between the guide rollers, with the right side of the limit guide plate attached to the upper guide plate. A lower guide plate is set on the left side of the loading and unloading assembly. The position of the Z-shaped loading and unloading plate is adjusted by a telescopic structure on the bottom plate. When the large-diameter straight pipe on the upper side of the Z-shaped loading and unloading plate moves to the left, the large-diameter straight pipe on the left side of the Z-shaped loading and unloading plate rolls to the lower guide plate, while the large-diameter straight pipe on the right side falls onto the guide roller through the limit guide plate, thereby automatically loading and unloading the large-diameter straight pipe.
