Abstract
A continuous oil pipe injection head driving device relates to a continuous oil pipe injection head of a continuous oil pipe operation equipment. The utility model comprises a driving box body, two hydraulic motors, two stage planetary gear reduction boxes, a hydraulic release type brake device, a driving shaft and a sprocket wheel, which is characterized in that the two stage planetary gear reduction box are respectively disposed on the two sides of the driving box by bolts; the driving shaft of the driving box is sequentially connected with a synchromesh gear and the sprocket wheel by splines; the driving power of the two hydraulic motors driven by the two stage planetary gear reduction boxes are connected with each other through the synchromesh gear to increase the lifting force and clamping capability of the continuous oil pipe injection head driving device. By using the utility model, the problems of the present continuous oil pipe driving devices, which has a small lifting force and clamping capability to clamp the tube with large tube diameter, can be solved.
Description
Technical field:
The utility model relates to the coiled tubing injection head of coiled tubing implement.
Background technology:
The coiled tubing implement is widely used in operations such as oil gas field well workover, drilling well, completion, well logging, and coiled tubing injection head is the power set that coiled tubing are lowered to and rise producing well.The drive unit of injection head mostly adopts the mode of arranging hydraulic motor and planetary gear reduction box in drive case both sides skew symmetry at present, its power passes through drive shaft reduction box power shaft by hydraulic motor, reduction gearbox output shaft drives the rotation of driving box drive shaft sprocket wheel again, thereby drives chain and grip block motion.The characteristics of this drive unit are that balance is better, startup stability is good, shortcoming is to be short of power, be only applicable to the less coiled tubing clamping of less coiled tubing injection head of specified pulling force and caliber, be not suitable for big coiled tubing injection head of specified pulling force and the bigger coiled tubing clamping operation of caliber.
Summary of the invention:
The purpose of this utility model is to provide the coiled tubing injection head drive unit of the big novel kind of drive of a kind of driving force, is suitable for driving bigger coiled tubing injection head of specified pulling force and the clamping operation of the coiled tubing of caliber greatly.
The utility model is to realize above-mentioned purpose by following technical solution.
The utility model coiled tubing injection head drive unit comprises driving box casing, hydraulic motor, twin-stage planetary gear reduction box, hydraulic pressure release type brake gear, driving shaft, sprocket wheel, it is characterized in that: two pairs of twin-stage planetary gear reduction box are installed in the drive case both sides with bolt respectively, the driving box driving shaft links successively by spline and synchromesh gear, sprocket wheel, and synchromesh gear is interrelated with the power of two pairs of hydraulic motors of the twin-stage planetary gear reduction box transmission of casing both sides by driving shaft.Twin-stage planetary gear reduction box two pairs of hydraulic fluid pressure motors oil-in and oil return opening back in parallel respectively links with the change discharge capacity pressure compensation axial plunger pump that is located on the continuous pipe implement.
When continuous oil pipe injection head drive unit moves, the power of two pairs of hydraulic motors is passed to the central axis of drive case through the twin-stage planetary gear reduction box, two pairs of synchromesh gears on the central axis, sprocket wheel move toward one another, two driving shaft driven in synchronism sprocket wheels have been realized, chain wheel drive two pairs are contained in the motion of the saddle type grip block on the sprocket wheel, have increased hoisting power and chucking power.
The beneficial effects of the utility model are:
Be installed in the drive case both sides by two corresponding amount hydraulic motors and twin-stage planetary gear reduction box symmetry, the driving box driving shaft links successively by spline and meshing gear, sprocket wheel, meshing gear is interrelated with the power of two pairs of CD-ROM drive motors of casing both sides, can provide driving force to injection head simultaneously, increase injection head and promoted chucking power.
Description of drawings:
