Description

Technical Field

[0001] The invention relates to the technical field of drilling equipment, in particular to an automatic feeding system of a torque force testing device for a drilling joint. Background Art

[0002] Offshore drilling operations are completed by offshore drilling platforms or drilling ships. The drill bit breaks the rock and forms a "channel" between the sea surface and the formation, allowing oil to reach the sea surface through this "channel" to complete the exploitation of the seabed oil reservoir. In the oil drilling process, the top drive (short for top drive device) plays an important role. It is one of the main power devices in drilling operations. The top drive will drive the drill pipe to rotate, and under the action of a certain drilling pressure, the drill bit will drill through the formation and drill downward. Breaking rocks requires a very large torque. Insufficient torque will directly lead to the inability to drill, delay operation time, increase operation costs and operation risks. In the formal drilling process, the torque of the top drive cannot be tested. Therefore, before drilling, it is necessary to test the torque that the top drive can provide to check whether it can meet the design standards to ensure the smooth implementation of the drilling operation.

[0003] Traditional drilling joint torque test devices usually rely on manual operation to control the feeding process. This method requires operator intervention and is easily affected by the operator's skill level and fatigue, which may lead to errors or inconsistencies in the testing process. Therefore, the present application discloses an automatic feeding system for a drilling joint torque test device to meet the test accuracy during drilling joint torque testing and reduce the impact of manual operation on the test results.

[0015] Compared with the prior art, the present invention provides an automatic feeding system for a torque force testing device for drilling joints, which has the following beneficial effects: 1. The automatic feeding system of the torque force testing device for drilling joints places the drilling joint to be tested on the first transport plate, and the first transport plate is tilted to one side so that the drilling joint to be tested is closely fitted with the limit block, and the output end of the push cylinder is used to push the driving plate to move. When the driving plate moves, the first synchronous plate and the second synchronous plate are driven to move relative to each other, so that the lifting plate slides in the through groove on the conveying plate under the drive of the lifting block, and the two ends of the lifting plate are fixedly connected with limit protrusions adapted to the limit groove, and the lifting plate and the conveying plate have the same curvature, so that the lifting plate and the conveying plate are closely fitted, so that the drilling joint to be tested can be put into the feeding system. When the lifting block moves, it can drive the fixed platform to move, thereby making the connecting arm deflect around the axis of the fixed rod, and then making the limit block rotatably connected to the connecting arm move on the first transport plate. When the limit block completes an up and down movement on the first transport plate, the drilling joint to be inspected that is tightly fitted with the limit block on the first transport plate can be put into the transport plate individually, and then, under the push of the output end of the pushing cylinder, the pushing plate is in contact with the drilling joint to be inspected, thereby completing the inspection of the drilling joint to be inspected, effectively improving the inspection efficiency of the drilling joint, reducing the steps of manual participation in the inspection, avoiding the generation of manual errors, and thus improving the inspection accuracy.

[0016] 2. The automatic feeding system of the torque force testing device for drilling joints allows the drilling joint to be tested to slide on the conveying plate, so that one end of the drilling joint to be tested contacts the moving plate, so that the fixed arm enters the interior of the drilling joint to be tested. At the same time, when the drilling joint to be tested is in continuous contact with the moving plate and extrusion occurs, the driving rod and the moving plate can be relatively displaced. When the moving plate moves to one side, the driving rod remains relatively fixed, thereby realizing the separation between the moving plate and the moving ring. When the moving plate moves, it can drive the rotating seat to move synchronously, thereby causing the rotating seat to drive the fixed arm to deflect around the axis of the deflection plate. The fixed arm is an arc-shaped structure deflected outward, thereby making the fixed arm fit closely with the inner wall of the drilling joint to be tested, thereby realizing drilling joints of different sizes, and effectively improving the scope of application.

[0017] 3. The automatic feeding system of the torque force testing device for drilling joints drives the synchronous movement of the connecting plate by the movement of the fixed component. When the connecting plate moves, it can drive the lifting rod to move in the guide slope. The guide slope is a triangle inclined to one side, so that the height of the lifting rod in the limit block is gradually reduced. At the same time, when the height of the lifting rod is reduced, the synchronous arm deflects around the axis of the connecting rod driven by the rotating rod. At the same time, when the synchronous arm deflects, it can drive the connecting plate to deflect at the same time, thereby completing the reversal of the fixed component. At the same time, the fixed rod slides on the connecting arm, so that the drilling joint can enter the drill pipe power clamp for inspection. Compared with the traditional inspection method, manual handling of the drilling joint is required to realize the inspection of the drilling joint, which reduces manual participation and improves the accuracy of inspection.

[0018] 4. The automatic feeding system of the torque force testing device for drilling joints, after completing the inspection of the drilling joints, drives the lifting rod to reset along the guide slope under the guidance of the guide rod through the elastic force of the reset spring, thereby realizing repeated inspection of the drilling joints, effectively improving the inspection speed, and further improving the inspection efficiency.
