Abstract

The invention discloses an offshore platform automation workover machine upper tube manipulator. The manipulator comprises a main arm, a manipulator device and a hydraulic control system. The top of the main arm is provided with a top seat, the top seat is provided with a rotary oil cylinder, and the rear side of the main arm is provided with a sliding rail and a lifting cylinder; there are two manipulator devices, one of the manipulator devices is hinged to the top seat of the main arm by a hinge shaft to form a rotating manipulator, and the rotating manipulator can be rotated by 180 degreesaround the top seat by the rotary oil cylinder; another manipulator device is mounted on a sliding rail of the back of the main arm by a connecting arm to form a vertical manipulator, and the verticalmanipulator can move up and down along the sliding rail under the control of the lifting oil cylinder; the hydraulic control device controls the rotary oil cylinder, the lifting oil cylinder and themanipulator device to achieve the rotation and lifting and clamping actions. The manipulator achieves the lifting of an oil pipe by alternating switching-on and switching-off and upward and downward moving of the manipulator, thereby improving work efficiency and reducing labor intensity, and the safety is good.

[0016] The present invention will be described in detail below with reference to the drawings and embodiments.

[0017] figure 1 Shown is a schematic diagram of the structure of the present invention.

[0018] The present invention provides a pipe loading manipulator for an automated workover rig on an offshore platform. The manipulator includes a main arm 1 and a manipulator device 2. 1 There are slide rails 5 and lifting cylinders 6 on the back; the manipulator device 2 is provided with two, one of the manipulator devices 2 is hinged on the top base 2 of the main arm 1 to form a rotating manipulator, and the rotating manipulator passes through the rotating cylinder 3. The control can rotate 180° around the top base 3 and push the oil pipe 7 into the derrick; another manipulator device 2 is installed on the slide rail 5 on the back of the main arm 1 through a connecting arm to form a vertical manipulator, and the vertical manipulator is in the lifting cylinder 6. Under the control of, it can move up and down along the slide rail 5 and transfer the oil pipe 7 sent from below to the rotating manipulator.

[0019] The main boom 1 is a telescopic structure. The main boom 1 is provided with a lifting arm 11 and a lifting cylinder 12, and a top end seat 3 is arranged on the top of the lifting arm 11. Under the control of the lifting cylinder 12, the top end seat 3 rotates together The manipulator can be raised and lowered with the lifting arm 11, and the bottom of the tubing is higher than the drill floor to facilitate the tubing to be sent to the wellhead position.

[0020] figure 2 Shown is a schematic diagram of the structure of the manipulator device of the present invention Figure one.

[0021] image 3 Shown is a schematic diagram of the structure of the manipulator device of the present invention Figure II.

[0022] The manipulator device 2 includes a bracket 21 and a manipulator. Both ends of the bracket 21 are equipped with a manipulator; the manipulator includes a linkage block 22, a linkage shaft 23, a pressing plate 24, a manipulator claw 25, and a clamping cylinder 26. The clamping cylinder 26 The cylinder body is fixed on the bracket 21, the other end is hinged with two linkage blocks 22, the linkage block 22 is installed at the end of the bracket 21 through the pressure plate 24; the two linkage blocks 22 are respectively fixedly connected to one end of the linkage shaft 23, and the manipulator claw 25 is fixed At the other end of the linkage shaft 23; the clamping cylinder 26 drives the linkage block 22 and drives the linkage shaft 23 to swing, and drives the manipulator claw 25 to achieve 0-90° overturning, and realize the clamping and loosening of the oil pipe 7 by the manipulator (such as Figure 4 Shown).

[0023] The manipulator claw 25 has an arc-shaped structure, the arc is adapted to the outer diameter of the grabbed oil pipe, and the inner surface is engraved with anti-skid patterns.

[0024] The manipulator device 2 is installed on the base of the drill floor and can be moved longitudinally to feed or take the tubing 7 into or out of the wellhead position.

[0025] The hydraulic control device controls the rotating cylinder 4, the lifting cylinder 6 and the manipulator device 2 to realize rotation, lifting and clamping actions.

[0026] The upper pipe manipulator is installed on the base of the drill floor through a sliding seat, and the oil pipe 7 sent from below is transferred to the rotary manipulator by the vertical manipulator, and the rotary manipulator pushes the oil pipe 7 into the derrick.

[0027] Figure 5 Shown is a schematic diagram of the working state of the present invention.

[0028] The working process of the present invention:

[0029] The vertical manipulator on the main arm 1 receives the oil pipe 7 sent from the chassis pipe raising manipulator, and the pipe raising manipulator is released. The vertical manipulator grasps the oil pipe 7 and moves upward under the drive of the oil cylinder, and sends it to the rotating manipulator. With the oil pipe 7 moving upward, the vertical manipulator is loosened to realize the lifting of the oil pipe 7; then, driven by the rotating cylinder 3, the rotating manipulator rotates 180° to prepare for the next pipe feeding.

[0030] The structure of the present invention is simple and reliable, and the oil pipe can be grasped and released only by the expansion and contraction of the oil cylinder, and the reliability is high; the present invention realizes the lifting of the oil pipe through the alternate switch and up and down of the manipulator instead of manually dragging the oil pipe through the hook on the derrick. Work efficiency, reduce labor intensity, and good safety.

[0031] The above-mentioned embodiments of the present invention are merely illustrative and not exclusive, and all changes within the scope of the present invention or equivalent to the scope of the present invention are encompassed by the present invention.
