Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing, and protection scope of the present invention is not limited to as described below:
As shown in Figure 1, a kind of installation knot of the mechanically driver type crown-block heave compensator directive wheel for ocean platform drilling well
Structure, it includes floating drilling platform 1, the rack 2 for being set to 1 top of floating drilling platform and the brill for being set to 2 top of rack
Earrings screw 4 and well drilling hoist, earrings screw 4 and well drilling hoist difference are arranged at the top of the floating drilling platform 1 for well derrick 3
Positioned at the left and right sides of rack 2, it is provided with vertically arranged guide groove in the Drilling derrick 3, is slidably installed in the guide groove
There is floating overhead traveling crane 7, the center sheave 8 for offering multiple tracks wire casing on its cylinder, the heave compensation are rotatably installed in floating overhead traveling crane 7
Device further includes hook 9, pull rod 11, wirerope 12, the displacement compensating mechanism I for being respectively arranged at 2 left and right sides of rack and right displacement
Compensation mechanism II, the displacement compensating mechanism I and right displacement compensating mechanism II are symmetrical set, the displacement compensating mechanism I
Including connecting rod 14, directive wheel 15 and compensation hydraulic oil cylinder 16, the cylinder barrel of compensation hydraulic oil cylinder 16 is articulated with 2 top of rack, hydraulic
Directive wheel 15 is hinged on the effect end of the piston rod of compensating cylinder 16, and hinge joint is located at the middle part of directive wheel 15, the company
One end of bar 14 is articulated with the middle part of directive wheel 15, and the other end of connecting rod 14 is articulated with the middle part of center sheave 8, the hydraulic benefit
The cylinder barrel for repaying oil cylinder 16 is articulated in rack 2, and the tail end of the wirerope 12 is fixed on earrings screw 4, the head of wirerope 12
Around multi-turn coiling after the directive wheel 15 of displacement compensating mechanism I on center sheave 8, the head end of subsequent wirerope 12 bypasses position at end
It is fixed on well drilling hoist after moving the directive wheel 15 of compensation mechanism II, one end of the pull rod 11 is fixed on floating overhead traveling crane 7, separately
One end is fixed with hook 9.
The well drilling hoist includes that motor C26, winding roller C27 and retarder, the motor C26 and retarder are respectively provided with
