Abstract
The utility model relates to a large torque hydraulic turntable. In oil field, when kelly stem is used to drill cement plug, casing mill shallow well, thread making and other under well job tasks, the power is turned from electricity power into hydraulic power, and then to mechanical power, the under well jobs are completed by transmitting the required torque to the kelly stem. The device is composed of a hydraulic power part and a pressurized turntable part, the use of a hydraulic motor is more convenient and reliable, a torque transmission device that is connected with a central tube by inner and outer hexagon concave and convex combination is used, which is convenient for the big torque transmission. The utility model can satisfy the minor well repair needs of big torque well repair, as well as the oil-gas-water well operation construction of major well repair condition that the minor well repair does not have, and has self-sealing function to realize cycling fluid sealed usage, improves the site operational condition, reduces the environment pollution.
Description
Technical field
The utility model and a kind of oil well repairing operation equipment, the improvement of the high pulling torque hydraulic swivel head device of heavy repair task is finished in particularly a kind of construction that is applicable to operations such as the down-hole cover mills, milling, drilling out, thread making by the light maintenance implement.
Technical background
When operation such as down-hole cover mills, milling, drilling out, thread making is finished in the oil field in workover treatment, need supporting workover platform, equipment such as heavy repair task machine are generally with high-power workover rig power and machine carousel is supporting fulfils assignment.There is the freight height, transportation, carrying inconvenience, machine carousel does not have problems such as flexibility, safety factor, and especially in the beach region, heavy repair task equipment is carried less than the well head scene, can't finish above-mentioned heavy repair task.Simultaneously, existing hydraulic swivel head can not provide enough big moment of torsion, and well head can not be set up the sealing circulation and cause environment pollution during the hydraulic swivel head construction.
Technology contents
The purpose of this utility model is to provide a kind of high pulling torque hydraulic swivel head device with flexible high pulling torque transmission, convert the power electricity consumption to hydraulic power, convert machine power again to, transmit the device that required torque to kelly bar is finished the underground work task by this device.This practical purpose is to realize like this, well site electric power is received on the hydraulic power source, hydraulic power source becomes the hydraulic pressure energy with power conversions, hydraulic pressure can be passed on the hydraulic motor of this device by high-pressure rubber pipe, hydraulic motor is by power transmission shaft, gear train, gear wheel, driving key, center torque transmitter, kelly bar by central tube, by its rotation of torque transmitter band, is fulfiled assignment.After adopting technique scheme, advantage of the present utility model be whole high pulling torque hydraulic swivel head device have flexible transmission, in light weight, simple in structure, be convenient to advantage such as carrying.
The high pulling torque hydraulic swivel head is made up of two parts: (1), hydraulic power part.To be power source pass to 3-position 4-way hand-operated valve reversal valve on the hydraulic swivel head with the hydraulic oil on the Hydraulic Station with fire-proof motor, realizes the rotating of rotating disk by hand-operated valve.What of the on-the-spot required torque of construction well workover can be realized by adjusting the valve that overflows.(2), sealing rotating disk part.The sealing performance of rotating disk is that the rotation self-sealing rubber core by the rig floor inner chamber is realized the dynamic and static sealing to kelly bar, oil pipe.Seal disc group by rig floor place central tube external diameter realizes the sealing to well head and rotating disk itself.Be provided with anti-reversing pawl device in the rotating disk and avoided instead changeing problem, and reaction torque steadily can be discharged.
Description of drawings
Fig. 1 is a high pulling torque hydraulic swivel head structural representation
(1) is that hydraulic motor, (2) are that gear wheel, (7) for connecting key, (8) for central tube, (9) be torque transmitter for housing, (5) for gear train, (6) for shift fork, (4) for power transmission shaft, (3) among the figure.
The specific embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing: having two high-pressure oil pipes to be connected on two interfaces of hydraulic motor (1) on the reversal valve, form hydraulic gyration, hydraulic motor (1) passes to moment of torsion on the central tube (8) by power transmission shaft (2), gear train (5), gear wheel (6), connecting key (7), central tube (8) is connected with transmitting large torque by inside and outside six sides are concavo-convex with torque transmission device (9), there is cubic hole at torque transmitter (9) center, corresponding with four directions, kelly bar place, torque transmitter drives kelly bar and fulfils assignment.Its rotation speed change is stirred the gear that it connects by shift fork (3), and changes the gears engaged group, forms different rotating speeds.This utility model can satisfy light maintenance operation drilling out, and constructions such as cover mills, milling, thread making, has the function of self-styled performance, can realize that circulation fluid is sealed in usefulness, has improved construction condition, has reduced environment pollution.
Claims (3)
1, a kind of high pulling torque hydraulic swivel head, comprise hydraulic motor (1), power transmission shaft (2), shift fork (3), housing (4), gear train (5), gear wheel (6), connecting key (7), central tube (8), torque transmitter (9) is formed, on two interfaces that it is characterized in that having two high-pressure oil pipes to be connected to hydraulic motor (1) on the reversal valve, form hydraulic gyration, hydraulic motor (1) is by power transmission shaft (2), gear train (5), gear wheel (6), connecting key (7) passes to moment of torsion on the central tube (8), and central tube (8) and torque transmission device (9) are by concavo-convex combination of inside and outside six sides.
2, high pulling torque hydraulic swivel head according to claim 1 is characterized in that there is cubic hole at torque transmitter (9) center, and is corresponding with four directions, kelly bar place.
3, high pulling torque hydraulic swivel head according to claim 1 is characterized in that shift fork (3) stirs the gear that it connects.
