Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
The first embodiment is as follows:
as shown in fig. 1-2, the device for replacing the flare tip of the ocean platform comprises a base 1, wherein a support structure 5 is rotatably connected to the base 1, the support structure 5 is connected with a steel wire rope 4, and two ends of the steel wire rope 4 are respectively connected with a flare tip 7 and a winch 6. The torch head 7 is provided with a structure connected with the steel wire rope 4, and the steel wire rope 4 suspends the torch head 7 from the upper part of the torch head 7. The winch 6 drives one end of the steel wire rope 4 connected with the torch head 7 to drive the torch head 7 to rise or fall. The support structure 5 rotates around the base 1, and then drives the steel wire rope 4 and the torch head 7 to rotate.
The supporting structure 5 comprises a rotating arm 2 and a lifting arm 3, the bottom end of the rotating arm 2 is rotatably connected to the base 1 through a bearing 9, and the rotating arm 2 rotates around the axial direction of the rotating arm; in practical use, two ends of the pull rope are respectively fixed on the rotating arm 2 and the output end of the driving part, and when the driving part pulls the pull rope, the rotating arm 2 rotates relative to the base 1.
The bottom end of the lifting arm 3 is rotatably connected to the top end of the rotating arm 2 through a shaft 8, and the lifting arm 3 rotates around the shaft 8. When the lifting arm 3 rotates, the top end of the lifting arm 3 is raised or lowered, so that the steel wire rope 4 and the torch head 7 are driven to be raised or lowered.
Two ends of the linear driving member 10 are respectively and rotatably connected to the middle of the rotating arm 2 and the middle of the lifting arm 3. The linear drive 10 is used to drive the lifting arm 3 to rotate about the axis 8, thereby raising or lowering the top of the lifting arm 3. The linear actuator 10 may be a hydraulic cylinder, an air cylinder, a linear motor, a linear slide, an electro-steel, etc.
The bottom of the inside of base 1 is provided with pulley 11 No. one, the rotor arm 2 with the inside of the junction of lifting arm 3 is provided with pulley 12 No. two, the inside on the top of lifting arm 3 is provided with pulley 13 No. three. And the steel wire rope 4 sequentially bypasses the first pulley 11, the second pulley 12 and the third pulley 13. The steel wire rope 4 penetrates through the base 1, the rotating arm 2 and the lifting arm 3, and when the rotating arm 2 and the lifting arm 3 are rotated, the steel wire rope 4 cannot wind around the base 1, the rotating arm 2 and the lifting arm 3, so that the winch 6 is not influenced to pull or loosen the steel wire rope 4.
