Description
Technical field
This utility model belongs to petroleum machinery, is related specifically to injection head.
Background technology
Injection head as the critical piece of continuous oil pipe operation, the weight of carrying coiled tubing, and for coiled tubing lifting and under enter to provide power.The most conventional injection head type of drive uses hydraulic driving mode, by engine in situ power taking, driving injection head hydraulic pump to provide power for injection head motor running by transfer case, manually the discharge capacity of the pressure regulator valve regulation pressure of injection head hydraulic pump, discharge capacity and injection head motor controls the moment of torsion of injection head lifting load respectively and hoists and the speed of lower drain line.Need to operate multiple valve member during operation and realize power and energy, automaticity is the highest；And hydraulic drive is more sensitive to the change of oil temperature, oil temperature change can affect the stability that system is run, injection head hydraulic system is owing to using closed system, during long-term operation, system heat generation amount is big, causing complete machine oil temperature in hydraulic system too high, system stability in the large is poor, and hydraulic drive has more energy loss in the course of the work, along with high pressure, at a high speed, high efficiency and the most quantizing, the noise of Hydraulic Elements and system increases.
Summary of the invention
The purpose of this utility model is to provide a kind of novel alternating current to drive injection head, this injection head uses power frequency electric after the operating of frequency converter timing rear drive alternating-current variable frequency motor drives power transmission shaft, right angle gear box and reduction box to slow down, finally providing power for injection head chain operating, this injection head can improve the stability of system, automaticity is high, efficiency is high.
For achieving the above object, the technical solution of the utility model is:
A kind of alternating current drives injection head, including main frequency conversion motor, secondary frequency conversion motor, power transmission shaft, right angle gear box, reduction box, drive sprocket, drive chain, grip block, injection head matrix, it is characterized in that: described main frequency conversion motor and secondary frequency conversion motor are fixed on injection head matrix, its output shaft is connected with power transmission shaft, power transmission shaft passes through Flange joint right angle gear box, right angle gear box is connected with reduction box by splined shaft, reduction box is connected with drive sprocket by spline, reduction box is bolted injection head matrix, grip block is loaded on driving chain, chain is driven to be loaded on drive sprocket, right angle gear box front end is also equipped with brake gear.
Equipped with cooling fan on main frequency conversion motor and secondary frequency conversion motor.
