Abstract
The utility model provides an electric direct driving device of the oil drilling windlass, essentially consisting of a roller car, a driven chain wheel, a driving chain wheel, an electromotor and a chain; wherein, the driving chain wheel is connected onto the axle of the electromotor, and the driven chain wheel is directly connected onto the axle of the roller car. The utility model has small transmission components, small consumption power, high work efficiency, light integrity weight and small occupation area. Besides, the rotary speed of the motor can be realized by adjusting the input frequency of the motor or changing the direct current voltage of the motor, being applicable to the requirements of drilling in various depths.
Description
Technical field
The utility model relates to a kind of lifting appliance that is used for oil drilling, particularly the direct drive unit of a kind of electrodynamic type of petroleum drilling machine winch.
Background technology
The winch of oil-well rig extensive use at present is to use the motor drives driven sprocket, and driven sprocket drives the reduction box (four speed) of a multiple gear ratios, and reduction box drives drum vehicle again.The winch floor space of this structure is big, the consumption steel are many, transmission is complicated, system effectiveness is low, it is big to adjust maintenance load aborning.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of floor space is little, in light weight, energy-efficient, easy to adjust, the direct drive unit of electrodynamic type of the petroleum drilling machine winch being convenient to keep in repair.
The purpose of this utility model is achieved in that mainly to be made up of drum vehicle, driven sprocket, drive sprocket, motor, chain, and drive sprocket is connected on the axle of motor.Driven sprocket directly is connected on the axle of cylinder.
Motor is two, and they can be arranged in drum vehicle one side, connects by the drive sprocket on it and chain, also can be arranged in the drum vehicle both sides, and the drive sprocket of every motor is connected on the driven sprocket on the drum vehicle two end axles by chain respectively.
Can on the axle of motor, install a cycloidal-pin wheel formula reductor additional.
The utility model has the advantages that: drive disk assembly is few, consumed power is little, high efficiency, overall weight is light, floor space is little.Rotating speed of motor can realize by incoming frequency of regulating motor or the DC voltage that changes motor, be applicable to the rig requirement of the various degree of depth.
The utility model is described in further detail below in conjunction with drawings and Examples.
