Abstract

The invention discloses an oil / electricity hybrid power rotary drilling rig transmission system, belongs to the technical field of vehicle manufacture, and aims to solve the problems of universally low transmission efficiency, energy recovery rate and reuse rate in the prior art. The oil / electricity hybrid power rotary drilling rig transmission system comprises a power system, a pressurization system, a power head system, a rotary system and a winch system, a super-capacitor, a rectifier / inverter I and a motor / generator I of the power system recover gravitational potential energy when a winch is lowered, and a central control unit controls the power system, so that a rotary drilling rig operates through the pressurization system, the power head system, the rotary system and the winch system. Transmission efficiency is improved by the aid of oil electricity hybrid power, the power of an engine can be effectively matched by parallelly connecting the motor / generator I at an output end of the engine, the gravitational potential energy generated when the winch is lowered is stored in the super-capacitor through the rectifier / inverter I and can be recovered when the winch is lowered, and energy is recovered and reused.

Description

technical field [0001] The invention belongs to the technical field of vehicle manufacturing, and relates to a hybrid power transmission system, in particular to an oil / electric hybrid power rotary drilling rig transmission system. Background technique [0002] The transmission mode of the traditional rotary drilling rig is that the engine is directly connected to the hydraulic main pump through the transfer case, and the controller is connected with various control valves to control various actuators to work. The power source of the system is only the engine. When drilling under a cycle condition, it will be affected by geological conditions and operating conditions, and its load is often in a state of change, which affects the stability of the engine output speed and the transmission efficiency is low; usually Under normal circumstances, the operator always opens the engine throttle to make the engine output at full power, which increases fuel consumption and has poor ener...
