The main characteristics of drilling rig

(1) with simple structure, installation and transportation module, A type derrickvision of open, the low level of the winch power installation, lifting, lowering. Thecorrection method with the simple and efficient screw, shim adjustment wayaround. The base for the folding box type structure, composed of an upper, lower base, monolayer height not more than 3m, a total of 6 major transport module.The drill floor adopts high, low table structure, convenient installation of well control equipment, but also reduces the installation height of the winch. The floorsurface can be equipped with a full set of hydraulic equipment, the whole surface formation, open, orderly. The control room and the fixed support detachment,fixed in the tank, reduces the effect of vibration on control instrument, prolong the service life of the instrument, improves the accuracy of.

(2) the winch with 1 450kW, 794r/min (fundamental frequency speed) uniaxialstructure AC variable frequency motor through two gear box drive roller, which has the advantages of light weight, small volume, small maintenance workloadand other advantages. Without clutch between the main motor and the roller,complete synchronization. Winch speed and control the energy consumption braking and AC frequency conversion control, under normal circumstances,hydraulic disc brakes only parking, positioning and emergency stop function, butalso has a manual control lowering function. Winch all operating parameters,including the drilling speed, hook position, various security settings, CNC frequency automatic drill bit feeding, energy consumption braking function,through the computer and the electronic control system to realize full digitalcontrol. Winch is arranged on the tank reaches the low background, not onlyconvenient installation, demolition; the winch unit after the center of gravity shift,increased the derrick put weight.

(3) disk consists of a 300kW motor and 1 gear reducer drive. Motor dynamic characteristics of soft, large speed range and high torque capacity. The output shaft of the motor is arranged on the rotary inertia brake, clutch usingLT500/200T. The rotation speed of the turntable can be in the range of 0 ~ 300r/min stepless speed regulation. According to the requirements of drilling technology to set the motor speed and torque, rotating speed and torque toobtain ideal. Turntable can achieve full digital control, over torque protection,reversal protection, power-off protection function. The whole device is designed as a transport unit, convenient to move, install and transport.

(4) the 1300HP pump is composed of 1 A12V190PZ L -3 diesel engine to providepower, by the combined narrow V belt drive 1300HP mud pump. The pumpdevice is composed of two modules, a module for the power module, a module for the mud pump module, power module and the mud pump module vertical layout.The pump is fixed on the base, the lower transmission shaft part of a base,designed to be sliding parts, adjusting the tightness of the belt tensioning device.Between the two module power transmission adopt universal shaft, two modulepositioning buckles, convenient, accurate, convenient and fast assembly and disassembly. Two modules to meet the requirements of the overall movement.
