Abstract
Description
Technical Field
[0001] This invention relates to the field of drilling equipment, and in particular to a multifunctional, multi-channel, straight-insertion connector. Background Technology
[0002] In existing drilling technologies, surface drilling rigs transmit drilling pressure and torque to the drill bit over long distances via drill pipe, driving the drill bit to complete rock-breaking drilling operations. This traditional drilling mode has significant technical drawbacks: single-drill-bit rock-breaking operations cause significant disturbance to the surrounding rock, and the drill pipe suffers severe wear during power transmission, directly affecting drilling efficiency and equipment lifespan. To address these issues, patent number 201710082518.8, entitled "A Downhole Torque Self-Balancing Cabled Drilling Tool System," proposes a dual-drill-bit counter-rotating rock-breaking scheme. This scheme balances the rock-breaking torque through the counter-rotating of the inner and outer drill bits, effectively reducing disturbance to the surrounding rock and drilling tool system; it also simplifies the structure of the surface drilling rig and drill pipe, reducing wear on drilling equipment and downhole tool systems, representing a significant technological innovation.
[0003] However, this drilling system uses bottom-hole power drive for rock-breaking drilling, and its structure integrates multiple drive motors and sensors. During actual production and assembly, power supply and signal transmission must be provided to these drive motors and sensors. The corresponding power and signal lines must be passed through each component above the drive motor and sensor in sequence until the entire drilling system is assembled. Due to the compact design of this drilling system, the power and signal lines are prone to mechanical damage during the threading process, severely affecting the reliability of equipment operation. Furthermore, during later optimization, iteration, or maintenance of the drilling system, if it is necessary to repair the motors or sensors located at the lower end, the entire drilling system must be completely disassembled, and the power and signal lines must be separated from the disassembled components one by one. This is not only cumbersome but also highly susceptible to secondary damage to the power and signal lines during disassembly and assembly, significantly increasing maintenance costs and downtime.
[0004] Furthermore, the joints between the current components of the drilling system only provide channels for power lines and signal lines. They have not been adapted and optimized for the modular design and modular connection of the drilling system. Therefore, they cannot meet the needs of targeted and rapid disassembly and reassembly of problematic modules and internal components during later iterations, upgrades, or maintenance of the drilling system. Summary of the Invention
[0005] The purpose of this invention is to provide a multifunctional, multi-channel, direct-insertion connector.
[0006] A multifunctional, multi-channel straight-insertion connector includes a straight-insertion upper connector, a straight-insertion lower connector, multiple upper connector copper sliding supports, multiple upper connector copper sliding parts, a lower connector copper sliding support, and a lower connector copper sliding part. The upper and lower straight connectors are axially inserted together. The inner protruding structure of the straight-insertion connector has multiple first copper sliding assembly holes distributed circumferentially. The upper end of the straight-insertion connector has multiple through-holes and second copper sliding assembly holes and second bolt holes that extend axially. The first copper sliding component assembly hole is connected to the second copper sliding component assembly hole; After multiple straight-insertion upper connector copper sliding support components and multiple straight-insertion upper connector copper sliding components are assembled, they are connected in the first copper sliding component assembly hole and the second copper sliding component assembly hole; After being assembled with multiple straight-insertion lower connector copper sliding support components and multiple straight-insertion lower connector copper sliding components, they are connected to the assembly holes of the second copper sliding component. Any upper connector copper slide can make sliding contact with any lower connector copper slide.
[0007] Preferably, both the upper and lower connectors are hollow cylindrical structures with openings at both the top and bottom.

[0009] Preferably, it also includes a limiting mechanism, which includes a first limiting ring, a second limiting ring, a third limiting ring, and a fourth limiting ring; The first limiting ring and the second limiting ring are respectively set on the protruding structure inside the straight-insertion upper connector and aligned with the assembly hole of the first copper slide. After multiple first bolts pass through the first bolt holes, the first limiting ring and the second limiting ring are fixedly connected by nuts. The first limiting ring and the second limiting ring can press down on the upper connector copper slide support and the upper connector copper slide of the straight-insertion upper connector from the upper and lower ends. The third and fourth limiting rings are respectively set at both ends of the straight-insertion lower connector and aligned with the circular assembly hole. Multiple second bolts pass through the second bolt holes and then the third and fourth limiting rings are fixedly connected by nuts. The third and fourth limiting rings can press down on the lower connector copper sliding support and the lower connector copper sliding component of the straight-insertion lower connector from the upper and lower ends. Preferably, the bottom of the protruding structure on the inner side of the upper connector is provided with an annular groove for installing a sealing ring, and the inner side of the sealing ring contacts the connection between the upper connector and the lower connector.
[0010] Preferably, a limiting plate is connected between each straight-insertion upper connector copper slide and the first copper slide assembly hole to restrict its circumferential movement.
[0011] Preferably, the copper slide support of the lower connector has three spring holes on the side away from the lower connector copper slide, and a spring is placed in the spring hole. When working, the spring squeezes the copper slide support of the lower connector and pushes the lower connector copper slide to fit tightly with the upper connector copper slide.
[0012] Preferably, the upper end of the copper slide of the straight-through upper connector and the lower end of the copper slide of the straight-through lower connector are respectively provided with wiring holes for transmitting signals or conducting electricity.
[0013] Preferably, the inner protruding structure of the straight-insertion upper connector is provided with a first oil pipe assembly hole, and the upper end of the straight-insertion lower connector is provided with a second oil pipe assembly hole. The first oil pipe assembly hole and the second oil pipe assembly hole are connected. The cooling circulation oil pipe is connected to the upper oil pipe connector and the lower oil pipe connector through the upper oil pipe connector fixing component and the lower oil pipe connector fixing component. The upper oil pipe connector and the lower oil pipe connector are fixed in the first oil pipe assembly hole and the second oil pipe assembly hole of the straight-insertion upper connector and the straight-insertion lower connector, respectively.
[0014] This invention is simple to operate, featuring a direct-insertion structure that allows for connection via a simple insertion action, eliminating the need for complex operations. This improves work efficiency, reduces interface wear caused by frequent insertion and removal, and provides a full-area gas-liquid channel on the inner side. The cooling oil pipe and the circular mounting hole of the direct-insertion connector form a circulating oil circuit to dissipate heat. Furthermore, the copper sliding components are assembled in a circumferential arrangement, allowing for the simultaneous transmission of multiple signals or conduction of multiple wires. The overall design of this connector meets the needs of subsequent drilling system upgrades or maintenance, enabling targeted and rapid disassembly and reassembly of problematic modules and internal components.
