-Compound transmission device is mainly used for the power transmission of mechanical drive drilling rigs and electromechanical transmission drilling rigs, and the two types of such device are belt transmission and chain transmission.
We can matufacture all type of drilling rig from 1000m-9000m, different configurations and styles, including Digital control VF rig,Mechanical cold weather rig, Electromechanical Rig ,DC rig,mechanical rig ,trailer drilling rig.techonlogy from USA.
-The compound box made by our Company is of integrated structure, with characteristics of easy to dismount and install, compact structure and high reliability.
The main characteristic of drilling rig:
1. Modularize design,block package structure,connected with pins between sections.
2. Connected with cardan shaft, easy to install,dismount and deliver.
3. Front opening mast, installed at low position, integrally lifting.
4. Auxiliary driving equipments which are used to lift the mast and deal with emergency cases.
5. Integral chain driving box.
6. According to the models equipped with wellhead equipment and mud circulation system
It possesses the advantages of safe,reliable and labor-saving operation,high automaticity,and low cost of operation
The rig used AC-VFD-AC drive inverter CNC integrated applications, vector control, bus communication, computer and PLC, such as mature technology advanced, the main function of the realization of full digital control. Derrick the main base for low installation, one lift. Drilling high-9m, drilling wellhead platform with mechanized tools. 50dB winch for the uniaxial one block VVVF structure, braking using dual-role EATON WCSB436 end water-cooled gas push disc brake and CNC braking energy, the use of auxiliary drive device can be automatically sent WOB Constant drill and emergency role. Wheel driving force provided by the winch motor, one file wuji governor.
1. Various drive modes for drilling rigs including “diesel engine + hydraulic coupling transmission +chain compound” “diesel engine +reducing gear box + narrow V belt compound” are available for option. The power is reasonable distributed for higher efficiency.
2. Either inner or outer speed change is optional for draw works of drilling rigs. Speed change is easy and fast by remote pneumatic control. Main brake is either band brake or hydraulic disc brake. Electric magnetic eddy current brake for auxiliary brake.
3. For drilling rigs over 4000m in drilling depth, rig floor is in two levels which is “front high rear lower” power and transmission system are installed on the rear low level and the rig power is transmitted to drive rotary table and catworks located on drill floor through bevel gear reducer and universal shaft.
4. Module designed, advanced technology, easy for assemble and disassembly.
5. drilling rig is fitted with bailing drum, mechanical friction cathead and rotary table drive device.
6. Independent driller cabin is on the user’s requirements.
7. Independent automatic drilling system could be equipped as the client’s requirements. to realize the intelligent control of pneumatic, electric, hydraulic and instrument system so that driller completes the total drilling operation in the cabin.
