Description
Technical field
The utility model belongs to variable-frequency motor field, is specifically related to the asynchronous top of directly driving of a kind of oil-well rig and drives variable-frequency motor.
Background technology
Electric drilling machine drives rotary drill rod by rotating disk or top and completes drill-well operation, direct current machine overload capacity was poor in the past, need often to safeguard, and explosion-proof ability is bad, the frequency conversion top-drive motor occurred in recent years, due to too much because of intermediate link, the probability that result in fault appearance increases greatly, along with the environment of oil-gas exploration and development is more and more severe, in order to reduce costs, raise the efficiency, accelerate In Oil Field Exploration And Development speed, user has higher requirement to equipment, ites is desirable to cancel gear and increase load-carrying ability.
Summary of the invention
The adverse effects such as the utility model object provides the asynchronous top of directly driving of a kind of oil-well rig to drive variable-frequency motor, replaces traditional motor and reductor, and the complex structure that avoiding slows down brings, efficiency reduction, noise increase, oil leakage, maintenance are frequent.
The utility model is achieved in the following ways the asynchronous top of directly driving of oil-well rig and drives variable-frequency motor, comprise machine shell, stator, rotor, main shaft, the two ends, left and right of machine shell are fixed wtih left end cap and right end cap respectively, the left end of main shaft is installed on left end cap by self-aligning roller bearing, in the both sides of aligning roller axle, sealing ring is housed, the right-hand member of main shaft is installed on right end cap by cylinder roller bearing, too sealing ring is housed in cylindrical roller axle both sides, the main shaft being positioned at machine shell inside is fixed wtih rotor, rotor is fixed on main shaft by expansion sleeve, the two ends of rotor are provided with mouse cage sliver, the position corresponding to described rotor at the inwall being positioned at machine shell is provided with stator, the left end cap of main shaft side is provided with ventilating opening, air-cooler is fixed on left end cap, and air-cooler is communicated with ventilating opening, the fan of air-cooler just in time correspond to ventilating opening, right end cap is provided with shutter, the position of described shutter is corresponding with ventilating opening, air-flow can be made to circulate fast, the heat produced when taking away electric machine rotation.
The beneficial effects of the utility model are not for mechanically to need the direct rotary drill rod of gear to complete drilling rod rotary drilling, circulating fluid, connect the multiple drill-well operations such as column, meet the working condition requirement such as permanent moment of torsion, invariable power of wellbore construction requirement, drilling time 20%-40% can be saved, prepayment lock of tool drilling occurs, improve drillng operation fail safe, reduce the maintenance, repair intensity of workman.
