Abstract

The invention relates to a tunnel boring machine, in particular to a coal mine rock roadway shoulder corner coal stripping device applied to a TBM (Tunnel Boring Machine). The device is safe and reliable, and can assist the TBM equipment in cutting and excavating the shoulder corner coal of the coal mine rock roadway. The two sides of the main beam X are each provided with a shoulder corner coal stripping device and a falling material collector, and the two shoulder corner coal stripping devices are the left side shoulder corner coal stripping device and the right side shoulder corner coal stripping device; a horizontal moving rail of the right shoulder corner coal stripping device is fixed on the main beam X, and a horizontal moving seat is connected to the horizontal moving rail in a sliding manner and is connected with a translation oil cylinder; the horizontal moving seat is connected with the external sleeve through a swinging oil cylinder, a shaft sleeve group and a swinging pin shaft; the horizontal moving seat is connected with the internal slide way through a telescopic oil cylinder and a telescopic pin shaft; the left side of the large cutting roller is connected with the small cutting roller through a bearing; the right side of the large cutting roller is supported on the internal slideway through a bearing.

Description

technical field [0001] The invention relates to a tunnel boring machine, in particular to a coal mine rock roadway shoulder angle coal stripping device applied to a TBM boring machine. Background technique [0002] Compared with other coal mine rock roadway construction methods, the use of TBM roadheader construction has the advantages of safety, efficiency, economy, and environmental protection. The tunnel sections constructed by the current TBM roadheader are all circular, but some construction units may require special-shaped sections due to special reasons such as the limited size of supporting equipment and the layout of tunnel pipelines, so they can only carry out secondary construction. Therefore, it is particularly important to develop a device that can assist TBM equipment in cutting and excavating shoulder coal in coal mine rock roadways to realize the one-time construction of special-shaped tunnel sections. [0003] Patent 201310527229.6 discloses a full-section ...
