Abstract

The invention belongs to the technical field of parts of coal mine underground mining equipment, and particularly relates to a two-drive telescopic roller cutting mechanism for an excavating and anchoring integrated machine. The two-drive telescopic roller cutting mechanism comprises cutting motors, a cutting arm, a speed reducer, a middle section cutting roller, telescopic section cutting rollers and cutting roller telescopic oil cylinders, the speed reducer is mounted on the cutting arm, and the two cutting motors are transversely and symmetrically arranged outside the cutting arm and connected with the input ends of the two sides of the speed reducer correspondingly and drive the speed reducer; and the middle section cutting roller and the telescopic section cutting rollers are mounted at the transverse shaft output ends of the speed reducer, the cutting roller telescopic oil cylinders are arranged in the telescopic section cutting rollers, and the telescopic section cutting rollers are arranged at the two ends of the middle section cutting roller and driven by the cutting roller telescopic oil cylinders to extend and retract towards the two ends. According to the two-drive telescopic roller cutting mechanism, the transverse shaft telescopic full-width cutting rollers are adopted, full-width excavating is achieved, one-time forming of the roadway section is achieved, the coal mine excavating efficiency and the roadway forming quality are improved, and the safe, efficient and fast excavating requirements for a large-scale mine large-section roadway are met.

Description

technical field [0001] The invention belongs to the technical field of underground mining equipment parts in coal mines, and in particular relates to a double-drive telescopic roller cutting mechanism for a bolt-digging integrated machine. Background technique [0002] At present, there are mainly three types of coal roadway excavation in my country: the first is the matching operation line of the cantilever type roadheader and the single bolter; the second is the matching operation line of the continuous coal miner and the bolter; the third is Integrated digging and anchoring machine. At present, the coal roadway excavation in my country is mainly based on the first type, which has a wide range of applications, but the excavation speed is relatively low. The second double-lane layout method, cross-transposition construction, has higher requirements on geological conditions. Under the condition of unstable roof conditions, the excavation speed will be greatly reduced, and it...
