The drilling winch provided by the utility model has the advantages of simple structure, strong practicability, small volume, light weight and high installation accuracy and transmission efficiency.
Description
Technical field
The utility model belongs to the oil-well drilling equipment technical field, relates to a kind of winch concretely.
Background technology
At present, domestic petroleum drilling winch in usefulness surpasses the rig more than 7000 meters, there are problems such as overall efficiency is lower, drilling parameter is relatively poor, volume is big, Heavy Weight, setting accuracy is poor, the low lifting transportation of driving efficiency is transfinited on the structure design, along with the increasing of drawworks horsepower, the engine installation of winch and transmission configuration also exist problems in addition.Particularly homemade winch is used still less on marine rig.
Domestic, external petroleum drilling winch in usefulness does not have planetary reduction gear to use as the retarder of winch at present.Mainly be the requirement of petroleum drilling winch high-power, at a high speed, technical the achieving no breakthrough on the high pulling torque.
The utility model content
The purpose of this utility model has been to provide the drilling well that a kind of volume is little, in light weight, setting accuracy is high and driving efficiency is high winch.
The technical solution of the utility model is as follows:
This winch comprises base, cylinder, first rotation motor, and described cylinder is connected on the described base, is connected with brake gear on described cylinder, and described first rotation motor connects first planetary reduction gear, and described first planetary reduction gear connects described cylinder.
Adopt the said structure key to be to adopt planetary reduction gear to be connected with transmission of power between the cylinder rotation motor, utilize that the planetary reduction gear moment of torsion is big, compact conformation, advantage that setting accuracy is high, thereby improve the rotation motor driving efficiency greatly, reduce overall weight and volume, also improved setting accuracy.
Described cylinder also is connected with second planetary reduction gear, and described second planetary reduction gear is connected with second rotation motor.
Arrange reasonably that by symmetrical expression every planetary reduction gear has two power intakes, has solved the dynamical problem of winch.Power can reach more than the 2800kw, is applicable to that 7000 meters (deep-well, superdeep well) the above rig on marine rig and the inland rig uses.
Described first planetary reduction gear also is connected with the 3rd rotation motor.
Described second planetary reduction gear also is connected with the 4th rotation motor.
Be connected by drum-shaped tooth type shaft coupling between described first rotation motor and second rotation motor, the 3rd rotation motor, the 4th rotation motor (3d) and described first planetary reduction gear and the corresponding coupling end of second planetary reduction gear.
Be connected by gear clutch between described first planetary reduction gear and second planetary reduction gear and the described cylinder.
Can satisfy an end job by power-transfer clutch, the other end is standby, reaches purpose of energy saving.
Described first rotation motor and second rotation motor, the 3rd rotation motor, the 4th rotation motor are selected high-speed broadband high power AC frequency conversion rotation motor for use.
On alternating frequency conversion technique, high-speed broadband high power AC frequency conversion rotation motor with its start balance, strong, the permanent power adjustment of overload performance is big, the power-factor of load is high, can be with advantages such as the permanent moment of torsion output of extremely low speed, electrical motor brushless sparks.
Beneficial effect: the utility model is simple in structure, and is practical, the drilling well winch that volume is little, in light weight, setting accuracy is high and driving efficiency is high.
