Description
Technical field
The utility model relates to a kind of wire rope-winch heave compensator, is one of equipment of floating drilling platform and drill ship indispensability.
Background technology
Heave compensator is one of important equipment ensureing that marine floating type drilling well normally works, increase work efficiency, its combination property directly affects the cost of winning of offshore oil, sea wind can be reduced, wave, the natural climates such as ocean current are on the impact of offshore boring island, improve drilling efficiency and safety, and the application life of drilling equipment can be extended.Usual ocean floating type drilling platform heave compensation system mainly comprises drill string compensation and riser system compensates 2 aspects.Drill string compensates can be divided into again several forms such as telescopic drill rod heave compensation, hook block heave compensation, overhead traveling crane heave compensation, fast line (dead line) heave compensation and winch heave compensation according to installation site and structure.
The common drawback that dead line (fast line), winch heave compensation exist is comparatively serious to the wearing and tearing of wire rope, regulates the pressure in accumulator, more complicated.Overhead traveling crane heave compensation has on the one hand and takies the little advantage of drill ship floor space and space, and pipeline is short, sealing less, does not need high-voltage flexible sebific duct, it is little to rub, bring larger difficulty not only to the design of derrick, require large, the baroque special derrick of intensity, and there is the problem such as high-altitude installation and maintenance inconvenience.
Utility model content
It is limited that the utility model is intended to overcome existing heave compensation system adjustable range, and the defect such as consume energy large, provides a kind of wire rope that relies on and increase heave compensation scope, the wire rope-winch heave compensator of the half Active Compensation scheme using ballast box balance hook to carry.Its technical scheme adopted is as follows:
Wire rope-winch heave compensator, comprises and puts pulley block frame, support, sky vehicle frame, hook block, ballast box, ballast box pulley block frame, automatic rope-arranging transmission, reduction driven wheel, winch axle, motor, winch drum, leading screw, turntable, braking mechanism, shift fork.Described support installing is at the top of derrick, and install at an upper portion thereof and put pulley block frame, described sky vehicle frame passes through wire rope, pulley top with on put pulley block frame and be connected, bottom is connected with hook block, described winch drum is arranged on turntable by winch axle, and by wire rope and the pulley on support with on put pulley block frame and be connected, described ballast box pulley block frame connects ballast box by wire rope one end, the other end connects another winch drum, rotating speed is passed to reduction driven wheel through driving gear by described motor, thus drive winch axle and winch drum, the convert rotational motion of winch axle is the rotating campaign of leading screw by gear drive by described automatic rope-arranging transmission, described shift fork is arranged on leading screw, and stir wire rope and move left and right, described braking mechanism is arranged in the middle part of turntable, brake block is placed in brake disc both sides.
The utility model tool has the following advantages: the advantage with wire rope heave compensator and crown-block heave compensator, wire rope-winch heave compensator belongs to half active compensation device, reaction saves the energy again fast, and the scope of heave compensation can adjust as required, adjusting range increases.

Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in Figure 1, wire rope-winch heave compensator, comprises and puts pulley block frame 1, support 2, sky vehicle frame 3, hook block 4, ballast box 5, ballast box pulley block frame 6, automatic rope-arranging transmission 7, reduction driven wheel 8, winch axle 9, motor 10, winch drum 11, leading screw 12, turntable 13, braking mechanism 14, shift fork 15.Described support 2 is arranged on the top of derrick, and install at an upper portion thereof and put pulley block frame 1, described sky vehicle frame 3 passes through wire rope, pulley top with on put pulley block frame 1 and be connected, bottom is connected with hook block 4, described winch drum 11 is arranged on turntable 13 by winch axle 9, and by wire rope and the pulley on support 2 with on put pulley block frame 1 and be connected, described ballast box pulley block frame 6 connects ballast box 5 by wire rope one end, the other end connects another winch drum 11, rotating speed is passed to reduction driven wheel 8 through driving gear by described motor 10, thus drive winch axle 9 and winch drum 11, the convert rotational motion of winch axle 9 is the rotating campaign of leading screw 12 by gear drive by described automatic rope-arranging transmission 7, described shift fork 15 is arranged on leading screw 12, and stir wire rope and move left and right, described braking mechanism 14 is arranged in the middle part of turntable 13, brake block is placed in brake disc both sides.
First according to the weight of the load adjustment ballast box 5 on hook, package unit is in equilibrium state in inactive state.When raising under the effect of production platform at stormy waves, rotating speed is passed to reduction driven wheel 8 through driving gear by motor 10, thus drive winch axle 9 and winch drum 11, winch drum 11 affects ballast box 5 to reduce by wire rope through ballast box pulley block frame 6, winch drum 11 drives overhead traveling crane frame 3 and hook block 4 by wire rope simultaneously, drill string is declined, raises to reduce production platform the impact brought to drilling well manufacturing process.When declining under the effect of production platform at stormy waves, rotating speed is passed to reduction driven wheel 8 through driving gear by motor 10, thus drive winch axle 9 and winch drum 11, winch drum 11 affects ballast box 5 height by wire rope through ballast box pulley block frame 6, winch drum 11 drives overhead traveling crane frame 3 and hook block 4 by wire rope simultaneously, drill string is raised, to decline the impact brought to drilling well manufacturing process to reduce production platform.When the state of emergency, package unit can be braked by braking mechanism 14, carry out emergency maintenance process.In the process of carrying out heave compensation, automatic rope-arranging transmission 7, leading screw 12 and shift fork 15 combine and winch axle 9 is continued unidirectional rotary motion are converted into swinging of shift fork 15 rule, thus realize the arrangement of wire rope rule.
Be illustrated the utility model by way of example above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
