Abstract
The utility model relates to an oil workover rig power-driven winch assembly, which comprises a motor, a coupler, a reduction gearbox, a clutch, a roller and a disk type brake, wherein an output shaft of the motor is connected with an input shaft of the reduction gearbox through the coupler; an output shaft of the reduction gearbox is connected with a shaft of the roller through a spline; and the disk type brake is formed by a brake disc and a brake caliper. The oil workover rig power-driven winch assembly has the advantages of simple and reliable transmission system, high transmission efficiency, wide constant-power speed adjustable range of a two-speed variable-frequency and variable-speed motor, small noise of the power-driven winch, no waste gas pollution, small maintenance load, low cost, accuracy and reliability of the disk type brake, easiness in realization of remote control and automatic control, and the like. The oil workover rig power-driven winch assembly can be applied to the field of electric drilling machines and workover rig winches.
Description
Technical field
The utility model relates to petroleum well workover machinery field, and especially a kind of petroleum well workover electromechanics drives the winch assembly.
Background technology
It is power that present China's oil service machine winch adopts diesel engine mostly; Diesel engine carries out remedial work through turbine transformer, change speed gear box, right angle gear box and drive chain case rear driving drum; The diesel-engined driven winch exists diesel engine work efficient low, has serious noise and exhaust emission; Engine maintenance care work amount is big, the maintenance and repair expense is high; Winch driving system circuit is long, and machinery driving efficiency is low; Problems such as the band brake brake torque is little, brake drum breaks easily.
Summary of the invention
The purpose of the utility model is in order to have overcome the deficiency of prior art, provides a kind of and has utilized electricity to drive the petroleum well workover electromechanics that winch replaces conventional diesel mechanomotive force strand and be widely used in electric drilling machine and service machine winch field to drive the winch assembly.
The utility model is realized through adopting following technical scheme mode: petroleum well workover electromechanics drives the winch assembly and is made up of motor, coupler, drop-gear box, power-transfer clutch, cylinder and disk type brake.Motor is a double speed ac variable frequency speed regulation motor, is connected with coupler between motor output shaft and the drop-gear box input shaft, is connected with spline between reduction gearbox output shaft and the drum shaft.Drop-gear box is the gear transmission drop-gear box, and disk type brake is made up of brake disc and braking clamp.
Compared with prior art, the beneficial effect of the utility model is:
1, machine driven system is simple and reliable, and driving efficiency is high.
2, motor is a double speed ac variable frequency speed regulation motor, and double speed variable-frequency motor acceleration and deceleration case speed change is compared with the mechanical gear box speed change and improved reliability greatly.
3, to drive the winch noise little for electricity, no exhaust emission.
4, the maintenance of motor service expenditure is low, and use cost is low.
5, adopt disk type brake as the winch main brake, disk type brake adopts fluid control, and brake torque is big, and brake reduces working strength of workers accurately and reliably greatly, makes the brake operation simple and flexible that becomes, and easily is automated and Long-distance Control.
Description of drawings
Fig. 1 drives winch assembly structure scheme drawing for a kind of petroleum well workover electromechanics.
Wherein: 1-motor; 2-motor output shaft; 3-coupler; 4-drop-gear box input shaft; 5-drop-gear box; 6-power-transfer clutch; 7-reduction gearbox output shaft; 8-drum shaft; 9-cylinder; 10-brake disc; 11-braking clamp.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is done and to be described in further detail:
Electricity drives the winch assembly and is made up of motor 1, coupler 3, drop-gear box 5, power-transfer clutch 6, cylinder 9 and disk type brake; Disk type brake is made up of brake disc 10 and braking clamp 11; Motor output shaft 2 is connected through coupler 3 with drop-gear box input shaft 4, and reduction gearbox output shaft 7 is connected with drum shaft 8 usefulness splines.
It is power with the double speed frequency control motor that this electricity drives the winch assembly; Through direct drive cylinder behind the gear reduction box, with conventional diesel engine be power, compare through turbine transformer, change speed gear box, right angle gear box and drive chain case rear driving drum structure; Simple and reliable, driving efficiency is high.
Below only be a kind of method that realizes the utility model, based on other way of realization of this inventive principle all within the protection domain of the utility model.
