Abstract
The utility model relates to an individual axle electric winch for hand drilling with electrical motor direct connected'comprised an AC frequency conversion, a brake disk, an integrated automatic driller, a base frame and a rolling drum. Wherein, a single-disk brake disc is provided on the one end of the rolling drum which is arranged on the winch frame and a large geared ring is provided on the other end and the axle of the drum is connected with the motor axle by a coupling, the integrated automatic driller is connected with the large geared ring by a pinion. The utility model uses the matching components of the low-speed high pulling torque AC frequency conversion electrical motor to drive the rolling drum directly, the gearless reduction gearbox, and the large-sized clutch coupling, forming a construction of uniaxial rolling drum motor winch of which the outer rotor and the rolling drum are integrated, the utility model has the advantages of simple structure and high reliability, uniform feeding using the integrated automatic driller, high speed, and high benefit.
Description
Technical field
The present invention relates to the drilling project apparatus field, particularly a kind of rig motor direct connection single shaft electrical drawworks.
Technical background
Existing rig electrical drawworks is to adopt one or more electrical motor to rotate by the cylinder that matching components such as gear reduction box, large-scale power-transfer clutch drive winch, this version causes winch to slow down or the deceleration of employing speed reduction gearing by multiaxis, the transmission complexity, control accuracy is low, adaptive capacity is poor, driving efficiency is low, send drill system to exist and send brill inhomogeneous, shortcomings such as the pressure of the drill instability.
Summary of the invention
The utility model is for solving the above-mentioned technical matters that existing winch exists, adopt the mode of motor direct connection to propose a kind of motor direct connection electrical drawworks, it has advantages such as simple in structure, that control accuracy is big, adaptive capacity is strong, driving efficiency is high, maintaining is simple.The objective of the invention is provides a kind of motor direct connection single shaft electrical drawworks for the scene.
Technical solution of the present utility model is: a kind of motor direct connection single shaft electrical drawworks, comprise alternating-current variable frequency motor, brake disc, integrated form automatic driller, base, cylinder etc., it is characterized in that: described cylinder is installed on the winch frame, cylinder one end dress single-deck formula brake disc, the other end is equipped with bull gear, alternating-current variable frequency motor links to each other with drum shaft by coupler, and alternating-current variable frequency motor and cylinder are installed on the same axis.
Above-mentioned integrated form automatic driller links to each other with bull gear by miniature gears.
Above-mentioned alternating-current variable frequency motor adopts the low-speed big motor.
The utlity model has following advantage: because alternating-current variable frequency motor is coaxial with winch drum, the motor direct-drive cylinder, matching components such as gearless drop-gear box, large-scale power-transfer clutch, be a kind of motor direct connection single shaft pattern, have compact conformation, control accuracy is big, the driving efficiency advantages of higher, integrated automatic bit feed system can realize that permanent the pressure of the drill creeps into, and send and bores evenly, and drilling quality is good, speed is fast, high efficiency.The utility model can be worked under frequency-changing control system, but more than fundamental frequency constant-power, stepless speed-regulating; Can permanent moment of torsion infinite speed variation below fundamental frequency, can satisfy the needs of drilling technologies such as making a trip better; When electrical motor is in 0 rotating speed, still has full torsional interaction.Very favourable to the settlement of accident of down-hole, sidetracking, well workover, little mud displacement operation, drilling with optimized parameter etc.The alternating-current variable frequency motor that uses can carry out the rotating both direction to be regulated, and all can realize working speed from 0～100% accurate step-less adjustment and use, drives winch and can cancel reverse gear, has simplified winch structure widely.
