Technical Field

The invention relates to the field of excavating machinery, in particular to a cutting drum of a tunneling and anchoring machine.

Background

At present, the coal roadway tunneling modes in China mainly comprise three modes: the first is a boom-type development machine and single jumbolter matched operating line; the second type is a matched operating line of the continuous miner and the anchor rod drill carriage; and the third is the tunneling and anchoring integrated tunneling of the tunneling and anchoring integrated machine. At present, the coal roadway excavation in China mainly takes the first kind as the main part, the application range is wide, but the excavation speed is low. The second double-lane arrangement mode is cross transposition construction, has higher requirement on geological conditions, greatly reduces the tunneling speed under the condition of unstable roof conditions, and is difficult to exert the advantage of rapid tunneling. The third type of tunneling and anchoring integrated machine performs full-width tunneling and one-step forming of the roadway section, and meets the requirement that a large-sized mine performs rapid tunneling on a large-section roadway strictly according to safety regulations. The used transverse cutting device of present domestic colliery tunnel tunnelling equipment is non-telescopic, and lacks intelligent control, and its shortcoming is: the tunnel can not be formed at one time, and continuous and rapid tunneling can not be realized; if one-step forming is desired, the tunneling equipment cannot be shunting, and the in-situ maintenance cannot be carried out when a fault occurs; the tunneling equipment is inconvenient to enter and exit the corresponding tunnel; the operator cannot precisely control the position of the coal plate and roof during the tunneling process.
