Abstract
The utility model relates to an uniaxial electric driving winch with external rotors for an oil drill. The utility model comprises a roller, a brake disc, an automatic bit feeding gear ring and a driving motor, wherein the driving motor is installed on the outer side of the winch roller, and the rotors of the driving motor are installed at both ends of the shaft of the winch roller and fixed on the roller coaxially. The rotors of the driving motor and the winch roller are supported by the same set (two) of bearings. A stator of the driving motor is directly fixed on bearing seats on both sides of the winch. One side of the winch roller is provided with the single-disc type brake disc, and the other side is provided with the gear ring for emergency driving and automatic bit feed. The uniaxial electric driving winch with external rotors is characterized in that the driving motor is closely combined with the winch roller to form an integrated electric driving winch, the rotors and the winch roller are coaxial without any reducer or driver among the rotors and the winch roller, therefore a uniaxial electric driving winch with external rotors is formed.
Description
Technical field
The utility model relates to oil drilling engineering equipment field, particularly a kind of single shaft external rotor electric driving reel cart for petroleum drilling machine.
Technical background
Existing oil-well rig electrical drawworks is that one or more electrical motor of employing rotates by the cylinder that speed-changing mechanism or device drive winch, and this version causes the necessary multiaxis of winch to slow down or adopts speed reduction gearing to slow down, the transmission complexity, and power transmission loss is big.
Summary of the invention
The technical matters that this patent will solve is to propose a kind of single shaft external rotor electric driving reel cart for petroleum drilling machine, and it is different with other electric winch, has advantages such as compact conformation, driving efficiency height, energy savings, can be provided on the nonpetroleum electric drilling machine.The purpose of this utility model is to propose a kind of single shaft external rotor electric driving reel cart for petroleum drilling machine.
To achieve these goals, the utility model is taked following technical scheme: comprise cylinder, brake disc, automatic bit feed gear ring, drive motor and base etc., it is characterized in that: drive motor is installed on the winch drum outside, the same axle mounting of drive motor and winch drum; Rotor is placed on the two ends of winch axle, and winch drum is fixed on the centre of winch axle, shared two bearings of rotor and winch drum, and motor stator directly is fixed on the bearing seat of winch both sides; One end of winch drum is installed single-deck formula brake disc, and the other end is installed the gear ring that is used for emergent driving and automatic bit feed; Bearing seat and single-deck formula brake disc are fixed on the base.
Drive motor and winch drum form integrated electrical drawworks with a winch axle.
Drive motor is made up of rotor and motor stator, and rotor and winch drum are assemblied on the same winch axle, and motor stator is fixed on the bearing seat of winch both sides.
The beneficial effects of the utility model are, because drive motor and winch drum are combined closely, rotor is coaxial with winch drum, no any deceleration in centre and driving device, and it has compact conformation, driving efficiency height, low power consumption and other advantages.So proposition of the present utility model has overcome the deficiency of existing electrical drawworks, can improve the efficient of oil-well drilling equipment elevator system, energy savings.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further details.
Fig. 1 is a structural representation of the present utility model
The 1-motor stator; The 2-rotor; The 3-bearing; The 4-bearing seat; 5-winch axle;
The 6-winch drum; 7-single-deck formula brake disc; The 8-gear ring; The 9-base
The specific embodiment
Referring to Fig. 1, rotor 2 and winch drum 6 are assemblied on the same winch axle 5, constitute a unified winch drum and winch assembly, and shared cover (two) bearing 3 is supported on the bearing seat 4.The both sides of motor stator 1 setting winch cylinder 6 are separately fixed at the both sides of bearing seat 4 equally.One side of winch drum 6 is a single-deck formula brake disc 7, and opposite side is emergent the driving and automatic bit feed gear ring 8.Winch drum 6, motor stator 1, rotor 2 and bearing seat 4 all are installed on the base 9.
Drive motor of the present utility model is different with common electric machine, the no bearing of motor itself, but overlap bearings 3 with winch drum 6 common uses one, thereby necessary speed change of conventional winch or speed reduction gearing have been removed, form real single shaft drawworks,, realize the stepless speed control of winch drum 6 by the rotating speed of frequency converter adjusting drive motor.Simultaneously, the both sides of winch drum 6 of the present utility model are separately installed with single-deck formula brake disc 7 and gear ring 8, are used for brake and emergent the driving and the realization automatic bit feed.
