Abstract
The utility model relates to an offshore drill winch comprises a main transmission system and an automatic drill delivery system. The offshore drill winch is composed of a main electric motor, a speed reducer, a drum shaft, a hydraulic disk type brake, an oil temperature and oil pressure inspection system, a pedestal, a primary transmission gear, a low-power electric motor, a shaft joint, a speed reduction gear box and a mill clutch. The offshore drill winch has small size, light weight and high transmission efficiency, and has the functions of remote control, hydraulic disk type braking, automatic drill delivery and electronic monitoring, and is convenient for transportation, and has high degree of automation, high winding speed and the like, is transported conveniently, has high automation degree, is safe and reliable in working, has fast uplifting speed, meets the operating requirements of a 7000m offshore drilling platform, and is widely applied to offshore oil drills.
Description
Technical field:
The utility model relates to a kind of core component that is used for offshore oil drilling equipment.
Background technology:
Along with the reinforcement of offshore oil exploration and exploitation work and the development of drilling technology, research, the improvement of offshore oil drilling equipment are strengthened year by year, are wherein crucial contents as the supporting winch of the marine rig of core component.At present, the supporting winch of offshore oil rig adopts dc powered winch and the two reduction box winches of AC frequency conversion mostly.Because the dc powered winch adopts chain drive, the transmission efficiency of its complete machine is reduced greatly, in addition, this type of winch is made up of power shaft, jackshaft, cat shaft, automatic bit feed axle and five axles of drum shaft, turntable is divided into preceding article and back bar, automatic bit feed mechanism is installed at the rear portion of winch again separately, has so not only increased the difficulty of processing and manufacturing, has also strengthened the appearance and size of winch.For convenient transportation, winch is divided into three, though made things convenient for transportation like this, has increased the installing/dismounting workload, has also increased the winch seal point, causes the winch leakage of oil easily, does not meet environmental requirement, and the weight of winch is increased.Though the two reduction box winches of AC frequency conversion are little, in light weight with respect to dc powered winch volume, its efficient is low, because this type of winch has only one grade, in order to satisfy the maximum pulling capacity of winch, just have to reduce the hoisting velocity of winch, so just greatly reduce the well-digging efficient of rig.With the JC70D winch is example, and its transmission efficiency is 0.895, and winch length is near 8 meters, and its weight reaches 50 tons, because ocean platform space and weight capacity are limited, so this winch has been not suitable for using on ocean platform.
The utility model content:
The purpose of this utility model provides that a kind of volume is little, in light weight, high efficiency and marine rig winch that can compliance with environmental protection requirements.
The utility model is to realize like this.This kind marine rig winch is made up of two 1100KW ac variable-frequency electric motors, reductor, travelling gear, ball cage type Hooks coupling universal coupling, drum shaft, air-cooled hydraulic disk type brake, 45KW ac variable-frequency electric motor, the clutch of turning a millstone, oily temperature oil pressure check system and base.This kind marine rig winch comprises the main transmission automatic bit feed system two parts of unifying, wherein, main transmission is made up of two 1100KW ac variable-frequency electric motors, shaft coupling, gear reduction box, one-level travelling gear, drum shaft, two main motors through shaft coupling synchronously with the power input gear reduction box, through the primary gear speed reducing driving roller shaft, finish the work operations of main transmission again; Automatic bit feed system is made up of low-power machine, reductor, push-plate clutch, reduction box, one-level travelling gear, drum shaft, a small-power 45KW ac variable-frequency electric motor is behind high pulling torque, big speed ratio reductor and push-plate clutch, pass to reduction box, through the primary gear speed reducing driving roller shaft, finish the automatic bit feed process again.Because motor has the characteristic of stepless speed regulation and counter-rotating, can obtain needed any hoisting velocity and speed reversal.Two parts integral body is arranged on the base, and drum shaft one side is provided with hydraulic disc brake, and fluid pressure line is provided with oily temperature oil pressure check system.
The utility model appearance and size is less, own wt is lighter, the transmission efficiency height, have functions such as remote control, hydraulic disc brake, automatic bit feed, electronic monitoring, its convenient transportation, automaticity height, safe and reliable, the hoisting velocity height is suitable for the instructions for use of 7000m marine drilling platform, is suitable for extensive use on the offshore oil rig.
Description of drawings:
Fig. 1 is the general structure schematic diagram of overlooking of the present utility model.Fig. 2 is that its A is to view.
Fig. 3 is its lateral view.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the utility model is made up of main motor 1,2, reductor 3, drum shaft 4, hydraulic disc brake 5, oily temperature oil pressure check system 6, base 7, one-level travelling gear 8, low-power machine 9, shaft coupling 10, gear reduction box 11, the clutch 12 of turning a millstone.Wherein, main motor 1,2 adopts the ac variable frequency speed regulation motor of power 1100KW high speed, wideband, high pulling torque.Reductor 3 adopts high pulling torque, big speed ratio reductor.Drum shaft 4 is whole single tumbling.Main brake hydraulic disc brake 5 adopts air-cooled one-sided single-deck hydraulic disc brake, can make full use of the sea wind cooling, saves forced cooling device.Low-power machine 9 is a 45KW ac variable frequency speed regulation motor, as the automatic bit feed system of winch.Shaft coupling 10 adopts the ball cage type Hooks coupling universal coupling.
