Pipe tamping type heading machine

Abstract

The invention belongs to the technical field of tunneling equipment, and particularly relates to a pipe tamping type heading machine which comprises an impact cutting assembly, a supporting shielding part and a scraper conveyor; the impact cutting assembly comprises a cutting frame and a pipe tamping hammer; one end of the pipe tamping hammer is connected with the cutting frame; the pipe tamping hammer pushes the cutting frame to conduct cutting tunneling; the supporting shielding part and the cutting frame are connected and move forwards together; supporting and protecting are conducted through the supporting shielding part; and the pipe tamping hammer and the scraper conveyor are both located in the supporting shielding part. The cutting frame is pushed to advance through the pipe tamping hammer, materials can be cut and extruded and crushed to a certain degree in the advancing process of the cutting frame, and if crushing is insufficient, manual supplementary crushing is needed, and the materials are conveyed out through the scraper conveyor. Along with continuous advancing tunneling, a channel is formed through the extension of a protective channel or permanent supporting of anchor rods, anchor cables and anchor nets. Therefore, through the structural arrangement, rescue channel tunneling operation can be carried out, and a roadway can be tunneled in a proper coal seam.

Description

technical field [0001] The invention belongs to the technical field of tunneling equipment, and in particular relates to a ramming tube tunneling machine. Background technique [0002] When a roof fall accident occurs in an unthrough tunnel or roadway, the workers are often blocked inside. How to quickly and safely open the rescue channel is the key to the success of the rescue. However, when excavating rescue channels, when encountering silt belts, loess belts, quicksand belts, cobblestone layers, scour zones, old empty areas and other surrounding rock broken areas, it is often difficult to dig rescue channels, and sometimes even give up rescue. There is an urgent need to research and develop a roadheader, which can not only ensure the safety of rescuers, but also safely and quickly pass through the surrounding rock crushing area for tunneling. Contents of the invention [0003] In view of the above technical problems, the present invention provides a rammer type roadhea...
