Description

Technical Field

[0001] The present invention relates to the technical field of extraterrestrial celestial body drilling test, and in particular to a clamping and monitoring system for a multifunctional soil and rock drilling sampling monitoring platform. Background Art

[0002] Existing extraterrestrial celestial body drilling simulation test platforms have significant technical limitations: devices with the capability of simulating extreme extraterrestrial environments are generally not integrated with the drilling and sampling function, while devices equipped with drilling and sampling functions are usually not adapted to the coupled working conditions of vacuum and low temperature. In response to this problem, the present invention proposes a multifunctional (single / multi-bit) drilling and sampling process monitoring platform and method for soil and rock in a vacuum and low temperature environment.

[0003] In order to enable the platform to support the drilling operation of single-bit conventional drilling tools and double-bit self-balancing drilling tools, realize rapid switching of clamping, centering and pressurization modes for different types of drilling tools on the same platform, and simultaneously have the in-situ detection capability of borehole wall morphology after the drilling test is completed, the single-drill double-holding system supporting the multifunctional soil and rock drilling sampling monitoring platform is of core technical necessity. Summary of the Invention

[0004] The objective of the present invention is to provide a clamping and monitoring system for a multifunctional soil and rock drilling sampling monitoring platform, which has the capability of compatible testing for single-bit and double-bit drilling tools, supports two modes of module downward pressing drilling and winch suspension drilling, can automatically adapt to a clamping or centering strategy according to the type of the drilling tool, and integrates the in-situ detection function of borehole wall morphology after drilling.

[0005] A clamping and monitoring system for a multifunctional soil and rock drilling sampling monitoring platform, comprising a hoisting system and a sliding conversion system: The hoisting system is used for hoisting and lowering the drilling tool; the sliding conversion system is used for clamping, centering and pressurizing the drilling tool, and the rotating electric turntable is used for switching between the camera mode and the drilling mode.

[0006] Preferably, the hoisting system includes a winch, an L-type speed reducer, a motion observation camera, a tension sensor, a hoist rope, a winch drive motor and a drilling tool; The winch is fixedly connected to the winch frame of the sealed chamber body for raising and lowering the hoisting rope; the L-shaped reducer is fixedly connected to the winch frame of the sealed chamber body, thus fixing the L-shaped reducer to the winch, for redirecting the motor's power; the motion observation camera is fixedly connected to the motion observation camera bracket of the sealed chamber body for real-time observation of the drilling status of the drill string; the tension sensor is placed in the middle of the hoisting rope, with both ends connected to the hoisting rope, for testing the tension value provided by the hoisting rope to the drill string; one end of the hoisting rope is connected to the winch drum, and the other end is connected to the drill string lifting ring for transmitting tension; the winch drive motor is connected to the lower end of the L-shaped reducer for providing power to the hoisting system; the drill string lifting ring of the drill string is connected to the hoisting rope, and its external structure includes the drill string lifting ring, the drill string feed port, and the drill string body, the drill string body being a drilling equipment with a built-in drill bit drive motor.

[0007] Preferably, the sliding conversion system includes a module drive motor, a module, a tow belt, a drill bit pressure sensor, a mechanical gripper, a rotating frame, an electric turntable, a turntable drive motor, a module sliding platform, and a pipeline camera; The module drive motor is fixedly connected to the upper side of the module. The module is fixedly connected to the module support frame of the sealed chamber body. One end of the tow strap is fixedly connected to the module support frame, and the other end is fixedly connected to the side of the module sliding platform. The drill bit pressure sensor is fixedly connected to the pressure sensor fixed end of the rotating frame and is used to measure the pressure provided by the module sliding platform to the drill bit. The mechanical claw is fixedly connected to the mechanical claw fixed end of the rotating frame and is used to clamp the drill bit. The turntable fixed end of the rotating frame is fixedly connected to the electric turntable. Its structure includes a camera extension tube, a pressure sensor fixed end, a mechanical claw fixed end, and a turntable fixed end, which are used to connect the pipeline camera and the mechanical claw together to form an axial angle, ensuring that the pipeline camera is located above the borehole while the drill bit can be moved away from the borehole after the electric turntable rotates. The electric turntable is fixed to the module sliding platform. The turntable drive motor is fixedly connected to the lower end of the electric turntable. The module sliding platform and the module slide in perpendicular contact. The pipeline camera is fixedly connected to the bottom of the camera extension tube of the rotating frame and is used to observe the borehole wall morphology after drilling.

[0008] Preferably, the rotating frame includes a camera extension tube, a pressure sensor fixing end, a mechanical claw fixing end, and a turntable fixing end. The rotating frame is used to connect the pipeline camera and the mechanical claw together to form an axial angle, ensuring that the pipeline camera is located above the borehole while the electric turntable can move the drill bit away from the borehole after rotation.

[0009] Preferably, the mechanical claw has a dual working mode of clamping and straightening, which can automatically adapt to the type of drill bit: for a single drill bit, the mechanical claw clamps the drill bit to provide counter-torque; for a dual drill bit self-balancing drill bit, the mechanical claw only straightens and does not clamp, and the drill bit relies on its own reverse rotation to offset the torque.

[0010] Preferably, the single-drill dual-hold system supports two modes: module-down drilling and winch-suspended drilling. When the module is in module-down drilling mode, the module drive motor drives the module sliding platform to move the drill bit downward, and the module provides axial pressure. When the winch is in winch-suspended drilling mode, the winch suspends the drill bit and uses the drill bit's own weight to lower it for drilling.

[0011] The beneficial effects of this invention are: This invention enables compatible testing of traditional single-bit drilling tools and dual-bit self-balancing drilling tools on the same test platform. It adapts to the anti-torque requirements of different drilling tools through a dual-mode clamping / aligning mechanism with mechanical claws, supporting both module pressing and winch suspension drilling methods to meet the needs of different test scenarios. An integrated electric turntable switching mechanism allows for rapid switching between drilling and borehole wall imaging modes, enabling quick in-situ detection of borehole morphology after drilling completion. Equipped with a multi-dimensional sensor monitoring system, it can simultaneously acquire drilling parameters and sample response parameters, which has significant scientific and engineering application value for studying the interaction mechanism between different types of drilling tools and soil / rock, and for evaluating drilling tool performance.

The 201 drum is connected at one end and the other end is connected to the drill string lifting ring A2071 to transmit tension; the winch drive motor A206 is connected to the lower end of the L-type reducer A202 to provide power to the hoisting system A2; the drill string lifting ring A2071 of the drill string A207 is connected to the hoisting rope A205, and its external structure includes the drill string lifting ring A2071, the drill string feed port A2072 and the drill string body A2073. The drill string body A2073 is a drilling equipment with a built-in drill bit drive motor. For detailed internal structure, please refer to the drill string part of the patent "A Bionic Self-Balancing Lunar Soil / Rock Micro-Disturbance Drilling and Sampling System Without Drill Rig" (CN117760778A). The drill string body A2073 can be clamped by the mechanical claw A305 and is the main carrier for drilling.

[0019] Furthermore, the sliding conversion system A3 includes a module drive motor A301, a module A302, a towing device A303, a drill bit pressure sensor A304, a mechanical gripper A305, a rotating frame A306, an electric turntable A307, a turntable drive motor A308, a module sliding platform A309, and a pipeline camera A310. Furthermore, the module drive motor A301 is fixedly connected to the upper side of module A302, providing controllable power to module A302; module A302 is screwed to the module support frame A1023 of the sealed chamber body A102, serving as the sliding track of the module sliding platform A309, converting the controllable power of the module drive motor A301 into axial pressure and displacement; the structure and connection method of the module drive motor A301 and module A302 are existing technologies and will not be elaborated upon here. One end of the towing device A303 is fixedly connected to the module support frame by screws, and the other end... The end is fixedly connected to the side of the module sliding platform A309 by screws, so that the circuit signal lines on the module sliding platform A309 can move in an orderly manner; the drill pressure sensor A304 is fixedly connected to the pressure sensor fixing end A3062 of the rotating frame A306 by screws, and is used to measure the pressure provided by the module sliding platform A309 to the drill A207; the mechanical claw A305 is fixedly connected to the mechanical claw fixing end A3063 of the rotating frame A306 by screws, and is used to clamp the drill A207, so that the drill A207 drills in the center of the soil sample A406; the rotating frame A305... The rotating platform fixed end A3064 of 06 is screwed to the electric rotating platform A307. Its structure includes a camera extension tube A3061, a pressure sensor fixed end A3062, a mechanical gripper fixed end A3063, and a rotating platform fixed end A3064. This structure connects the pipeline camera A310 and the mechanical gripper A305 together to form an axial angle, ensuring that after the electric rotating platform A307 rotates, it can move the drill bit A207 away from the borehole while the pipeline camera A310 remains above the borehole opening. The electric rotating platform A307 is screwed to the module sliding platform A309 for rotating the rotating frame. A306; The turntable drive motor A308 is fixedly connected to the lower end of the electric turntable A307 with screws, providing controllable power for the rotation of the electric turntable A307; The module sliding platform A309 is in vertical sliding contact with the module A302, used to connect the electric turntable A307 and the equipment on it to the module A302, and the module sliding platform A309 can slide vertically along the module A302 under the drive of the module drive motor A301; The pipe camera A310 is fixedly connected to the bottom of the camera extension tube A3061 of the rotating frame A306, used to observe the morphology of the borehole wall after drilling.

[0020] Working principle of the invention: Drilling Mode 1 (Module Downward Drilling): In this mode, the winch A201 does not provide tension to the drill string A207. Instead, the module drive motor A301 drives the module A302, which in turn drives the module sliding platform A309 and its connected electric turntable A307, rotating frame A306, and other equipment to provide axial force for vertical movement. At the same time, the real-time parameters of the module drive motor A301 are converted with the fixed structure of the module A302 to calculate the drilling displacement and speed.

[0021] When using the dual-bit self-balancing drill string A207 (where the inner and outer drill bits rotate coaxially in opposite directions, their torques cancel each other out, and no external counter-torque is required), the pressure provided by module A302 is applied to the top of drill string A207 via drill string pressure sensor A304 through the rotating frame A306. Drill string pressure sensor A304 measures the pressure applied to drill string A207 by rotating frame A306, while mechanical gripper A305 uprights drill string A207 but does not provide clamping force, only limiting the lateral sway of drill string A207, allowing drill string A207 to descend stably.

[0022] When using a traditional single-drill tool A207 (which only starts one drill bit and requires external counter-torque), the tool A207 is clamped by a mechanical claw A305 to provide counter-torque. The axial pressure provided by the module A302 is transferred to the rotating frame A306, and the mechanical claw A305 and the pressure sensor fixed end A3062 on the upper part of the rotating frame A306 together provide downward pressure. The total pressure value is calculated from the data of the module drive motor A301.

[0023] Drilling Mode 2: Winch Suspension Drilling: This mode is only available for the dual-bit self-balancing drill bit A207. The winch A201 suspends the drill bit A207 for lowering and raising the drill bit. The drilling pressure of the drill bit A207 is entirely provided by its own weight.

[0024] (3) Real-time parameter monitoring Drilling pressure: In drilling mode one, when using the traditional single drill bit A207, the drilling pressure is provided by module A302 and can be converted by the parameters of the module drive motor A301; when using the dual drill bit self-balancing drill bit A207, its drilling pressure is equal to the value of the drill bit pressure sensor A304 connected on the rotating frame A306.

[0025] Drilling speed and torque: Real-time feedback from the motor of the drill bit A207 itself.

[0026] Drilling speed: obtained from the relationship between the displacement of module A302 and the lowering displacement of winch A201 and time.
