1.Brief introductions of ZDY-3200S full hydraulic tunnel drilling rig

The ZDY3200S full hydraulic tunnel drilling rig for coal mine is mainly used for drilling holes of large diameter gas (row), grouting and fire prevention holes, coal seam flooding holes, anti outburst and pressure relief holes, water penetration holes, geological exploration holes and other engineering drilling holes. It is suitable for all kinds of coal and rock drilling. But the rock strength coefficient of needs to be under 10. Appropriate drill bits and drill pipes can be used for coring, soft coal seam drilling and other engineering operations.

2. Features of ZDY-3200S full hydraulic tunnel drilling rig

The ZDY3200S full hydraulic tunnel drilling rig is a combined structure of all hydraulic power head. It consists of four parts: the hydraulic pump station, the power head, the rack, the operation floor and the column support.

The breakage performance is good. The components are light in weight. It is easy for underground driller to move and shift, and the drilling rig structure layout is flexible.

The rig has unique hydraulic system and double pump. The rotary parameters of drilling rigs and the feeding parameters can be independently regulated, which improves the adaptability of drilling rig to various drilling processes.

The power head gyrator adopts the structure of double motor and transmission spindle through hole, and the length of drill pipe is not restricted by the drilling machine, that is to choose the drill pipe with different length according to the construction conditions of the underground drilling field.

The hydraulic chuck and the hydraulic gripper are used for unloading the drill pipe, which is simple, labor-saving, efficient and safe.

The oil pipe connection is between the operation platform, the pump station and the main engine, so you can operate it intensively and the personnel can operate far away from the wellhead to protect personal safety.

Four column support, lifting cylinder will adjust the fuselage (drilling inclination angle), which is convenient and labor-saving.

With variable pump, it has infinite variable speeds regulation and great adaptability in different working conditions.
