The rotary table of the composite drive drilling rig is driven by electricity, and the winch and mud pump are driven by diesel engines, overcoming the problems of high cost of electric drive, mechanical transmission route, and climbing drive of the rotary table of the mechanical driven high drilling platform. It meets the requirements of modern drilling technology and has strong market competitiveness. The main models include ZJ30LDB, ZJ40LJDB, ZJ50LJDB, ZJ70LDB and other drilling rigs.

Technical characteristics

● Using a "diesel engine+hydraulic torque converter (or coupling main body)+chain parallel body" to drive the winch and mud pump; AC variable frequency motor or DC motor driven rotary table can achieve stepless speed regulation, break through torque limitations, and improve drilling performance;

The host module adopts a "front high and rear low" layout, and the power and transmission systems are installed at a low position;

The main brake adopts hydraulic disc brake, and the auxiliary brake uses electromagnetic eddy current brake. Variable speed inside the winch, pneumatic remote operation for gear shifting, convenient and fast;

Box type or "front rotary lifting and back block installation" structural base, with a flat drilling surface, large operating space, good power mutual benefit, and high power utilization rate;

● Can meet the requirements of inter site migration during cluster drilling;

Through PLC, the entire drilling process logic control, monitoring, and protection can be achieved, with data storage, printing, and remote transmission functions.
