Description

TECHNICAL FIELD

The disclosure relates to the technical field of coal mine roadway tunneling support, and in particular to a six-arm tunneling and anchoring machine.

BACKGROUND

A longitudinal-axis roadheader is equipped with a jumbolter, a bridge stage loader, a belt conveyor and ventilation and dust removal equipment, so as to form a tunneling system. Due to its high tunneling flexibility and wide application geological conditions, a roadway tunneling technology based on the longitudinal-axis roadheader is most widely applied.

During a tunneling process of the longitudinal-axis roadheader, the longitudinal-axis roadheader firstly tunnels a certain distance and then retreats, the jumbolter moves to the front of the roadheader for roadway support, after the roadway support is completed, the jumbolter moves to the back of the roadheader, and the longitudinal-axis roadheader moves forward to perform the next tunneling cycle.

Due to a narrow space of a coal mine roadway and an undulating bottom plate, after the tunneling of the roadheader is completed, the jumbolter moves forward, and water, electricity and air pipelines need to be moved forward at the same time, thereby taking a long time and having high labor intensity of workers; a roadway top plate has a long empty top time; the bottom plate is uneven, such that the working environment is poor; there are a large amount of equipment, such that the degree of mechanization is low; and there are many hidden safety hazards in the roadway.
