Description

Technical Field

[0001] This utility model relates to the field of oil drilling technology, and in particular to an oil drilling rig tool handling system. Background Technology

[0002] A derrick is a device used during drilling operations to house the overhead crane, suspend traveling blocks, hooks, lifting rings, and clamps, as well as to handle and store drill pipe, tubing, and sucker rods. A derrick consists of the main body, the crane platform, the crane frame, the second-level platform, the riser platform, and the working ladder. The second-level platform is the work area for derrick workers to perform drilling operations; it includes the derrick worker's work platform and finger beams for storing tubing and tools.

[0003] Pipes are essential tools in oil and gas drilling. During drilling, multiple pipes are typically connected end-to-end within the wellbore. These pipes are linked by threaded connections at their ends, and are used by drillers for connecting and disconnecting them. Slips are tools used during tripping in and out of the drilling rig to hold and suspend the drill string and casing string.

[0004] At present, although there are many large pipe handling equipment, such as top drives, hydraulic hoists, and iron drills, they are not systematic and standardized enough. A large number of workers are still needed to assist in the handover and transfer of pipes, which poses safety risks and has low work efficiency.

[0041] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0042] Example 1:

[0043] like Figure 1 , Figure 2 and Figure 8 As shown, this embodiment provides a drill string processing system for an oil drilling rig, including a two-tier manipulator 1, a drill platform manipulator 2, a power slip device 3, a steel drill bit 4, a thread cleaning device, and a traveling hoist system. The two-tier manipulator 1 is installed on the second tier of the derrick, and the traveling hoist system is vertically and movably installed on the derrick. The drill platform manipulator 2 and the steel drill bit 4 are installed on the drill platform, and both can operate close to the wellhead. The power slip device 3 is installed at the wellhead. The thread cleaning device includes a male thread cleaning assembly 5 and a female thread cleaning assembly 6. The male thread cleaning assembly 5 and the female thread cleaning assembly 6 are installed on the drill platform. The male thread cleaning assembly 5 can clean the male thread of the drill string located at the wellhead, and the female thread cleaning assembly 6 can clean the female thread of the drill string located at the wellhead.

[0044] Specifically, the system integrates the second-level platform robot 1, the drilling platform robot 2, the power slip device 3, the iron drill 4, and the thread cleaning device into a single system, achieving fully automated connection of the entire process from second-level platform transfer, drilling platform loading and unloading, thread cleaning to wellhead connection. Compared to traditional manual or independent equipment operation, this reduces waiting time between processes and equipment changeover time, significantly shortening the processing cycle of a single drill string and substantially improving drilling operation efficiency. The second-level platform robot 1 replaces manual labor in grasping and transferring drill strings at height, avoiding risks such as falls from heights and impacts from objects; the drilling platform robot 2 and the iron drill 4 precisely complete the docking and tightening of drill strings, reducing drill string damage or personnel injury caused by uneven torque during manual operation; the thread cleaning device automatically cleans the pipe threads, preventing operators from coming into contact with oil, debris, and other harmful substances, reducing occupational health risks. The entire system reduces the risks of human operation and significantly improves operational safety. The male thread cleaning assembly 5 and female thread cleaning assembly 6 provide professional cleaning for the male and female threads of the drilling tools, effectively removing oil, mud, rust, and other impurities from the thread surface to ensure a tight thread engagement when the drill bit is connected. Compared to manual wiping, the cleaning effect is significantly improved, reducing connection failures caused by thread contamination, extending the service life of the drill bit, and lowering equipment replacement and maintenance costs.

[0045] Furthermore, such as Figure 3 and Figure 4As shown, the male thread cleaning assembly 5 includes a column 51, a swing mechanism 52, a first lifting driver 53, a first thread cleaning mechanism, and an oiling assembly.

The oiling assembly is disposed on the top of the first thread cleaning mechanism.

[0046] Furthermore, such as Figure 3 and Figure 4 As shown, the first cleaning mechanism includes a first sliding seat 541, a first turntable 542, a first rotation driver 543, and multiple sets of first cleaning components. The first lifting driver 53 is connected to the first sliding seat 541, the first sliding seat 541 is slidably mounted on the column 51, the first turntable 542 is rotatably mounted inside the first sliding seat 541, multiple sets of first cleaning components are evenly arranged on the top of the first turntable 542, the first rotation driver 543 is mounted on the first sliding seat 541, and the first rotation driver 543 is connected to the first turntable 542 to drive the first turntable 542 to rotate and drive the multiple sets of first cleaning components to rotate around the central axis of the first turntable 542.

The first reset assembly is disposed on the first turntable 542, and the reset end of the first reset assembly abuts against the first slider 545. When the first turntable 542 rotates, it can drive the first cleaning brush 544 to slide away from the center of the first turntable 542 via the first slider 545. When the first turntable 542 stops, the first reset assembly can cause the first slider 545 to drive the first cleaning brush 544 to reset.

[0048] Furthermore, such as Figure 5As shown, the oiling assembly includes a fixed cylinder 551 and multiple oil nozzles 552. The fixed cylinder 551 is disposed on top of the first cleaning mechanism, and the multiple oil nozzles 552 are evenly arranged on the outer side of the fixed cylinder 551. The oil spraying end of the oil nozzle 552 extends into the interior of the fixed cylinder 551 from the side wall of the fixed cylinder 551 and faces the center of the fixed cylinder 551. Specifically, the oiling assembly also includes a photoelectric switch 553, an oil spray switch 554 connected to the oil inlet end of the oil nozzle 552, and a pneumatic solenoid valve 555 connected to the air inlet end of the oil nozzle 552. The signal transmitting end and signal receiving end of the photoelectric switch 553 are respectively arranged on both sides of the fixed cylinder 551 and extend into the fixed cylinder 551. When the male thread of the pipe fitting extends into the fixed cylinder 551, the male thread of the pipe fitting separates the signal transmitting end and the signal receiving end of the photoelectric switch 553. The signal receiving end cannot receive the signal emitted by the signal transmitting end. When the height of the male thread of the pipe fitting corresponds to the height of the fuel injector 552, the fuel injector 552 starts to inject fuel.

[0052] Furthermore, such as Figure 6 and Figure 7The second cleaning assembly includes a second cleaning brush 644, a second slider 645, and a second reset assembly. The second cleaning brush 644 is radially slidably mounted on the second turntable 642 via the second slider 645. The second reset assembly is disposed on the second turntable 642, and the reset end of the second reset assembly abuts against the second slider 645. When the second turntable 642 rotates, the second cleaning brush 644 can be driven to slide away from the center of the second turntable 642 via the second slider 645. When the second turntable 642 stops, the second reset assembly can cause the second slider 645 to drive the second cleaning brush 644 to reset.

Specifically, the top drive is movably mounted on a vertical guide rail on the derrick, enabling it to move the hydraulic jack up and down along the vertical guide rail. The top drive also enables the hydraulic jack to flip and float (returning to its initial position from the flipped position). During tripping operations, the top drive drives the hydraulic jack to perform the lifting, transfer, and lowering of the piping.
