Abstract
The utility model relates to a novel main hoist floating system for a rotary drilling rig, which comprises a floating electromagnetic valve, a brake, a braking and unlocking electromagnetic valve, an energy accumulator, a hydraulic control reversing valve, a check valve, a throttler, a balance valve and a main hoist motor. The energy accumulator is connected with the braking and unlocking electromagnetic valve, the check valve and the hydraulic control reversing valve. Energy accumulation of the energy accumulator is realized by transformation of gravitational potential energy which is generated when a drill rod is descended by a main hoist or the characteristic that when the main hoist lifts up the drill rod, the pressure of a working oil circuit of a main pump can charge the energy accumulator liquid through the hydraulic control reversing valve. The energy accumulator is used as a pressure oil source of a brake oil circuit of the main hoist floating system. A maximum working pressure of the energy accumulator is regulated by the hydraulic control reversing valve and is maintained by the check valve. A floating function of the main hoist is realized by reversing of the floating electromagnetic valve and the braking and unlocking electromagnetic valve and pressure release of the energy accumulator. The novel main hoist floating system is easy to integrate floating function elements with the hoist motor and the balance valve, is easy to distribute pipes and is convenient to integrate pipelines. The rate of failure occurrence of the pipelines is effectively reduced. Meanwhile, the novel main hoist floating system has a certain energy-saving effect.
