Embodiment 1

[0063] like image 3 As shown in the figure, the device is in the working state at this time, and the control box controls the oil cylinder 7 to extend through the control pipeline 8, so that the main mechanical arm 4 and the gripper 61 and the mechanical arm 6 generate an included angle; 61 The rear balance rod 42 and the balance arm 5 form a parallelogram link 44 structure; the gripper 61 and the gripper 61 mechanical arm 6, the gripper 61 front balance rod and the balance arm 5 also form a parallelogram link 44 structure; when When the oil cylinder 7 is extended, the main mechanical arm 4 will rotate around the hinge of the connecting seat 3, so the gripper 61 can extend in the horizontal direction; after reaching the designated position, the gripper 61 will grab the pipe string and grab the pipe string. Then control the oil cylinder 7 to retract to move the pipe string to the center of the wellhead, and then cooperate with the workover oil hoisting system to complete the mak...

Embodiment 2

[0065] like Figure 4 As shown in the figure, the device body is in a standby state at this time, the oil cylinder 7 retracts, and the gripper 61 mechanical arm 6 is recovered to the position overlapping with the main mechanical arm 4; at this time, the main mechanical arm 4 and the gripper 61 mechanical arm 6 are in a vertical position state, retracted on the side of the work platform 1, leaving the space of the work platform 1 for the rest of the tools and personnel to work.

Embodiment 3

[0067] like Figure 5 As shown in the figure, the device is in a transport state at this time, and the manipulator on the upper part of the device is put down and folded; the oil cylinder 7 is retracted, so that the gripper 61, the manipulator 6 and the main manipulator 4 are upright and overlapped, and the locking pin 9 is inserted to connect the gripper 61 and the manipulator 6 with the main manipulator 4. The main mechanical arm 4 is connected and fixed to ensure that it will not spread out during folding and transportation; then the latch 32 is removed, and the connecting base 3 can rotate around the fixing pin 31 at this time, so that the entire mechanical arm above the connecting base 3 rotates around the support base 2. After the robot arm is lowered as a whole, a bracket is used to fix the lowered robot arm on the work platform 1, and the device body and the work platform 1 are transported together.

Abstract

The invention discloses an oil pipe pushing and supporting manipulator device of a minor repair platform and a use method thereof, relates to the technical field of special equipment for wellhead devices of an oil field workover platform, and is a special manipulator device for a workover platform. The device is installed on the wellhead platform device through the fixed plate, and the mechanical arm is driven by the hydraulic cylinder to perform telescopic movement in the horizontal direction. The end of the mechanical arm is equipped with a manipulator, and the manipulator is equipped with a finger clamp and a telescopic cylinder. Grabbing is carried out under the drive of the telescopic cylinder. , Release action. The invention has the advantages of compact structure, large working radius, high degree of automation, convenient operation, safety and reliability, and is suitable for automatic upgrading and transformation of new and in-service small workover rigs.

Description

technical field [0001] The invention relates to an auxiliary mechanical device for workover wellhead operations in an oil field, in particular to a small workover platform tubing pushing and supporting manipulator device and a method for using the same. Background technique [0002] At present, domestic workover and minor workover is a risky project with huge investment. The quality of workover equipment directly affects the workover speed, the health and safety of workers and the economic benefits of operation. At present, the wellhead operation is mainly manual operation when the oil pipe is started and operated in the domestic workover and minor workover operation. When tripping out, the driller uses the workover rig to lift the tubing out of the pipe string from the wellhead, and two wellhead workers use wellhead tools to complete the shackle of the tubing, and push the tubing to the catwalk tray or pull it to the ground by hand; Two wellhead workers will pull the pipe ...
