CMQ2-1200/55(K), CMQ2-1000/55(K) Coal mine roofing drilling rig

Yancheng Qunli Industrial and Mining Machinery Co., Ltd., in order to meet the actual demand for coal pillar-free mining technology construction in underground coal mines, successfully implemented the "110 construction method" with gob reservations along the mining face, adapted to the coal mine roof cutting and pressure relief construction operation method, and developed and produced the CMQ2-1200/ on the basis of many years of experience in the design and manufacturing of coal machinery. The 55(K) series roof-cutting drilling rig for coal mines has received national utility model patents for its hydraulic integrated oil circuit, anti-sag functional device and fast drilling and retraction design. The patent numbers are: ZL201921493884.3, ZL201921493204.8, and ZL202222393971.X. This drilling rig is a new type of multi-functional coal mine roofing drilling rig that integrates drilling, roofing and seam cutting. It is used for the construction of underground roofing, seam cutting and blasting blastholes. This airborne drilling rig has hydraulic lifting, upper support can be adjusted 15° in pitch and has a self-locking function. The hydraulic rotation drives the power head, so that the power head can achieve ±90° drilling operations in the vertical direction and ±180° drilling requirements on the facade. All fuselage oil pipes use invisible connections, which greatly improves safety performance. In the process of "top cutting, pressure relief, and gob tunneling", this drilling rig has good hole-forming quality, small angle error, and all drilled holes can be relatively aligned in a straight line. The whole vehicle has the advantages of small size, easy disassembly and assembly, simple operation, strong functions, and many actions. Strict inspection methods and performance tests ensure product quality.
