Abstract

The invention belongs to the technical field of coal mine tunneling equipment, and particularly relates to a coal mine arched section cutting system. Comprising a self-walking round section cutting device, a following type trimming cutting device, an anchor protection system, a rear matched power system and a discharging system, the self-walking round section cutting device is arranged at the foremost end of a roadway with a round section, and the following type trimming cutting device is arranged behind the self-walking round section cutting device. The distance between the following type trimming and cutting device and the self-walking round-section cutting device is automatically controlled through a distance control system, the following type trimming and cutting device trims a roadway with a round section into a roadway with an arch-shaped section, and an anchor protection system is integrated on the following type trimming and cutting device and is responsible for completing the supporting procedure of the roadway; and a rear matched power system and a discharging system are arranged behind the following type trimming and cutting device, and the rear matched power system provides electric power and hydraulic power for the self-walking round section cutting device, the following type trimming and cutting device, the anchor protection system and the discharging system.

Description

technical field [0001] The invention belongs to the technical field of coal mine excavation equipment, in particular to a coal mine arch section cutting system. Background technique [0002] With the development of integration and integration of fully mechanized excavation equipment in coal mines, more and more full-face roadheaders are used. However, at present, the section of the roadway formed by the full-face excavation system is circular, while the section of the roadway required in the coal mine is arched. The completed roadway of the full-face excavation system needs to be backfilled into an arch to meet the use requirements of the coal mine, which increases the construction period. , reducing the economy. Contents of the invention [0003] In order to solve the problem that all roadways constructed by a full-section excavation system need to be backfilled into arches to meet the use requirements of coal mines, the present invention provides an arched section cutti...
