[0001] The invention relates to the technical field of marine engineering, and in particular to a load test tool for a drilling hoisting system. Background Art
[0002] The drilling hoisting system is one of the key systems of the drilling system. Load testing of the drilling hoisting system is an essential and key link in the drilling assembly and manufacturing.

[0014] Beneficial effects of the present invention: 1. This kind of drilling hoisting system load test fixture is provided with a reaction force component. The reaction force component significantly amplifies the initial pulling force of the pulling pump by combining two pulling pumps with a pulling force of 10t, a first amplification module and a second amplification module. The combination of a fixed pulley and a movable pulley effectively utilizes the mechanical advantage of the pulley, so that the original pulling force acts on the load plate after multiple amplifications, generating a greater reaction force. Combined with the lever structure, the pulling force transmitted by the movable pulley is further amplified by reasonably adjusting the amplification ratio of the force arm and the load arm, thereby more accurately controlling the test load, so that the reaction force can be flexibly adjusted according to on-site needs, greatly improving the control accuracy of the load, and by setting a suitable amplification ratio, the limited pulling force can be converted into sufficient reaction force to ensure that the force borne by the load plate meets the test requirements.

The positioning plate in the buffer assembly guides the slider to move smoothly through the slide rail. The slider cooperates with the staggered rotating plates and positioning wheels to ensure uniform force distribution, reduce stress concentration, and avoid sudden impact. The positioning rod and the buffer spring gradually absorb and disperse the force generated by the rising load rod. The buffer spring gradually compresses when it is subjected to force, and continues to absorb the impact force as the force increases, so that the load plate remains stable during the force process, thereby improving the safety and stability of the system.

[0021] like Figures 1 to 8 As shown, the drilling lifting system load test tooling includes a drilling platform 1 and a lifting ring 2 connected to an external top drive device, a connecting tool 3 is arranged below the lifting ring 2, a weighing sensor 4 is connected below the connecting tool 3, and a movable module is connected below the weighing sensor 4. The movable module includes a plurality of shackles 5 fixedly arranged below the weighing sensor 4, two groups of annular steel cables 6 are arranged below the plurality of shackles 5, and movable load rods 7 are arranged below the two annular steel cables 6. A fixed module is also arranged below the drilling platform 1, and a load plate 8 is movably installed in the middle of the lower end of the fixed module, the load plate 8 is adapted to the movable load rod 7, and the load plate 8 is arranged in a trapezoidal shape; a buffer component, the buffer component is arranged on the load plate 8 On both sides of the lower part, the buffer assembly is used to initially buffer the rise of the movable load rod 7; two reaction force assemblies, the reaction force assemblies are arranged on both sides of the drilling platform 1, and one end of the two reaction force assemblies is respectively rotatably connected to the two ends of the load plate 8, the reaction force assembly includes a driving module, a first amplifying module and a second amplifying module, the driving module is used to provide initial power to the reaction force assembly, the first amplifying module and the second amplifying module are used to amplify the force generated by the driving module, wherein the upper load limit of the lifting ring 2 and the weighing sensor 4 are both set to 500t, the drilling platform 1, the movable load rod 7, the load plate 8, the mounting base 18, the mounting frame 19, the fixing frame 26, and the lever are all set to DH36 material; At the beginning of the test, the main top drive drives the connection tool 3, the weighing sensor 4 and the active module to move upward through the lifting ring 2. The weighing sensor 4 monitors the load of the lifting ring 2 and the system in real time. When the load reaches a certain height, the shackle 5 in the active module drives the two sets of annular steel cables 6 to rise synchronously, and further pulls the active load rod 7 to rise. When the top of the active load rod 7 contacts the load plate 8, the buffer assembly begins to absorb the initial impact caused by the rise of the active load rod 7 to ensure the smooth transmission of the load. At the same time, the load plate 8 of the fixed module is pressed downward by force. The two ends of the load plate 8 are connected to the two sides of the drilling platform 1 through the reaction force assembly. The drive module in the reaction force assembly is started to provide initial power for the system. Through the first amplification module and the second amplification module, the initial power is amplified and generates a large reaction force, which further pushes the load plate 8 downward to apply a greater force. In this way, the reaction force is evenly transmitted to the active load rod 7 through the trapezoidal design of the load plate 8, and the load of the entire system gradually increases until the load reaches the preset standard. At this time, the weighing sensor 4 monitors the load data in real time to ensure the accuracy of the load and the safety of the system during the test.

A positioning rod 16 is also arranged in the middle of the positioning plate 10 through the slider 12, and the slider 12 is slidably connected to the positioning rod 16, and the positioning rod 16 is located on both sides of the slider 12.

The positioning plate 10 in the buffer assembly guides the slider 12 to move smoothly along the slide rail 11 through the slide rail 11 at its bottom. The two sides of the slider 12 are staggeredly connected by the first rotating plate 13 and the second rotating plate 14 installed by rotation. During the force-bearing process, the positioning wheel 15 starts to rotate to ensure that the force between the rotating plates and can be evenly distributed to reduce the impact concentration phenomenon. At the same time, the slider 12 drives the positioning rod 16 when moving, and the buffer springs 17 on both sides of the positioning rod 16 begin to compress, gradually absorbing the force generated by the rise of the movable load rod 7 to provide a buffering effect. As the force increases, the buffer spring 17 is further compressed, and the slider 12 moves smoothly to continue the buffering process, ensuring that the load plate 8 will not be suddenly subjected to excessive impact force, thereby protecting the stability and safety of the entire system.

After the steel wire rope 21 passes around the first fixed pulley 22 and the second fixed pulley 23, it is transmitted to the first movable pulley 24 and the second movable pulley 25. The pulling force of the pulling pump 20 is amplified by the action of the first movable pulley 24 and the second movable pulley 25.

When the movable load rod 7 rises and contacts the load plate 8, the load plate 8 is pushed downward under the reaction force from the load arm 28, and the load is gradually increased. , until the system reaches the preset test load, wherein by setting two pull pumps 20 with a pull force of t, and combining the first amplification module and the second amplification module, the system can significantly amplify the initial pull of the pull pump 20, and by using a combination of a fixed pulley and a movable pulley, the mechanical advantage of the pulley is effectively utilized, so that the pull of 10t can be amplified multiple times, thereby generating a greater reaction force on the load plate 8 and cooperating with the lever to further amplify the pull transmitted through the movable pulley, the amplification ratio of the force arm 27 and the load arm 28 can be flexibly adjusted according to the site conditions, which provides great freedom for the precise control of the load force, and by setting a reasonable amplification ratio, the lever can further convert the pull amplified by the movable pulley system into a greater reaction force, acting on the load plate 8, thereby achieving the expected test load.
