Abstract

The invention provides a paste filling pipe expansion device, which belongs to the technical field of filing equipment. The device comprises a fixed pipe port, wherein two hydraulic cylinders are axially and symmetrically arranged on the outer surface of the fixed pipe port, and the piston rods of the two hydraulic cylinders are arranged in the same direction; and the inner surface of the fixed pipe port is provided with an expansion pipe port, the outer surface of the expansion pipe port is tightly contacted with the inner surface of the fixed pipe port, two connection columns are symmetrically and radially arranged on the outer surface of the out end of the expansion pipe port, and each connection column is connected with the end port of the piston rod on the corresponding side. The filling pipe expansion device can be quickly and automatically dissembled and assembled with the pipe, so time and labor are saved and working efficiency is improved.

Description

technical field [0001] The invention relates to a mine paste filling equipment. Background technique [0002] The current filling pipelines are all connected by a plurality of straight pipes, and every two connected straight pipes are fixedly connected together by pipe clips. Although this connection method is relatively firm, when dismantling or installing a faulty pipeline, it is necessary to open the connecting pipe clip for maintenance, which is time-consuming and laborious, and has potential safety hazards. Therefore, it is imperative to develop a pipeline expansion device that is convenient for disassembly and assembly, time-saving and labor-saving. Contents of the invention [0003] Aiming at the defects in the prior art, the invention provides a telescoping device for a paste filling pipeline. The pipeline expansion device can be quickly and automatically disassembled from the pipeline, saving time and effort, realizing unmanned operation on site, and improving w...
