Description

Technical Field

[0001] This invention relates to a linkage clamping device for extraterrestrial drilling systems, belonging to the field of space sampling and exploration. Background Technology

[0002] To facilitate environmental and resource exploration of extraterrestrial bodies, drilling and sampling are among the core missions of the probe. Due to the probe's structural size limitations, the drill bit needs to be folded and compressed during launch and flight to reduce its folded size. Simultaneously, to accommodate drilling depth requirements, the drill bit often requires multiple extension mechanisms, resulting in numerous moving parts for compression and numerous structures that need to be avoided during unlocking. This necessitates that the compression and release mechanism be designed to allow for obstacle avoidance while ensuring effective compression, while also considering mass and energy constraints. Adopting a multi-functional and multi-point linkage compression design can effectively reduce mass and the use of pyrotechnics. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art. The present invention provides a linkage clamping device for an extraterrestrial drilling system, which realizes the function of clamping the drilling tool at multiple points and releasing it reliably.

[0004] The technical solution adopted in this invention is: a linkage clamping device for an extraterrestrial drilling tool system, comprising a guide rail drilling tool assembly clamping component, a guide rail support and drill rod limiting component, and a linkage rope; The guide rail drill bit assembly clamping component is located at one end of the drill rod of the impact drill and is used for clamping and releasing between the drill rod, guide rail, and detector. The guide rail drill bit assembly clamping component is connected to the guide rail support and drill rod limiting component located at the other end of the drill rod via a linkage rope. When the impact drill and guide rail are unlocked, the linkage rope is released to release the guide rail support and drill rod limiting component. The guide rail support and drill rod limiting component is used for guide rail support and drill rod limiting.

[0005] Furthermore, the guide rail drill assembly clamping component includes a clamping seat, a release nut, a clamping rod, a guide rail connector, an impact drill connector, a limiting cylinder, a spherical pad, a clamping nut, a support spring, a sleeve, and a linkage rope seat with an inflection point and an inflection point. A release nut is installed on the top of the clamping seat. The guide rail connector and the impact drill connector are connected in series and clamped to the top of the clamping seat by the clamping rod. A sleeve is installed on the impact drill connector, a pressure nut is installed at the end of the clamping rod, a limiting cylinder is installed on the clamping rod, and a spherical pad is installed in the ball socket in the center of the limiting cylinder. The limiting cylinder is located between the pressure nut and the impact drill connector. A support spring is installed between the limiting cylinder and the impact drill connector. A protruding structure on the side of the limiting cylinder extends from the opening on the side of the sleeve. A support plate is set on one side of the clamping seat. A turning point on the linkage rope seat is set at the end of the support plate. The turning point is located between the guide rail drill assembly clamping component, the guide rail support, and the drill rod limiting component.

[0006] Furthermore, the clamping seat is fixedly connected to the aircraft cabin panel, the guide rail connector is fixedly connected to one end of the guide rail, and the impact drill connector is fixedly connected to the impact drill.

[0007] Furthermore, when the guide rail drill assembly is in the clamping state, the limiting cylinder and the impact drill connector are connected to the rope head of one end of the linkage rope through the protruding structure on the side, so that the support spring is compressed; the linkage rope passes through the inflection point and then connects to the guide rail support and the drill rod limiting assembly.

[0008] Furthermore, when the guide rail drill assembly clamping component is in the unlocked state, the release nut detonates, releasing the clamping rod; the combination of the limiting cylinder, ball washer, clamping nut and clamping rod, driven by the support spring, bounces up to the top of the sleeve, releasing the guide rail connector and impact drill connector; after the limiting cylinder bounces up, the rope end is released, and the rope end of the linkage rope is pulled away into the limiting hole at the inflection point on the linkage rope seat.

[0009] Furthermore, the guide rail support and drill rod limiting assembly includes a limiting seat, a twin screw, a guide rail support frame, a pulley shaft, a pulley, a rotating arm torsion spring assembly, a crank torsion spring assembly, a tilting arm, a movable pressure plate, an adjusting pin, a fixed pressure plate, and a crank. The limiting seat has a frame structure. One end of the twin screw is installed at the bottom of the limiting seat, and the other end is connected to the guide rail support frame. By rotating the twin screw, the guide rail support frame can be raised or lowered to control the support position of the guide rail. Two pulleys are symmetrically installed on the guide rail support frame, and the pulleys rotate through the pulley shaft. A rotating arm torsion spring assembly is installed on the top of the support rod on one side of the limiting seat; the tilting arm is rotatably mounted on the top of the support rod on one side of the limiting seat via the rotating arm torsion spring shaft, and the rotating arm torsion spring assembly drives the tilting arm to tilt; the tilting arm is a bent rod, and a movable pressure plate, an adjusting pin and a fixed pressure plate are installed at the bend position to achieve drill rod limiting; A crank torsion spring assembly is installed on the top of the support rod on the other side of the limit seat; the crank is rotatably mounted on the top of the support rod on the other side of the limit seat via the crank torsion spring shaft, and the crank torsion spring assembly drives the crank to flip; one end of the crank is connected to the rope end of the linkage rope, and the other end of the crank is provided with a hook that cooperates with the hook at the end of the flipping arm.

[0010] Furthermore, when the guide rail drill assembly clamping component is in the clamping state, one end of the crank is pulled by the linkage rope, and the other end presses down on the tilting arm; by adjusting the position of the movable pressure plate by adjusting the adjusting pin, the drill rod is pressed down to achieve drill rod limiting.

[0011] Furthermore, when the guide rail drill assembly clamping component is unlocked, the rope end is released, the linkage rope is relaxed, and the crank torsion spring assembly drives the crank to rotate; the crank pushes the rope end to move, so that the linkage rope is pulled away from the clamping position of the guide rail drill assembly clamping component; the crank rotates to release the rotating arm, and the rotating arm rotates under the drive of the rotating arm torsion spring assembly, releasing the drill rod and thus avoiding the movement space of the impact drill.

[0012] The advantages of this invention compared to the prior art are: (1) The present invention cleverly adopts a linkage design to solve the problem of unlocking multiple clamping points with one ignition device, effectively saving system resources and reducing system quality.

[0013] (2) The combination design of the torsion spring and the compression spring of the present invention realizes the release function of the clamping device.

[0014] (3) The present invention eliminates the assembly gap of the mechanical system through the design of double helix and adjusting pin, and solves the problem of support and limit of slender parts. Attached Figure Description

[0022] The present invention will be described in conjunction with the accompanying drawings.

[0023] like Figures 1-3 As shown, a linkage clamping device for an extraterrestrial drilling system includes a guide rail drilling tool combination clamping assembly 1, a guide rail support and drill rod limiting assembly 2, and a linkage rope 3.

[0024] The guide rail drill bit assembly clamping component 1 is a clamping and releasing functional component between the drill bit, guide rail, and detector. It is connected to the guide rail support and drill rod limiting component 2 via a linkage rope 3. Unlocking the drill bit and guide rail releases the linkage rope 3, thereby releasing the drill rod limiting component 2. Through this linkage mechanism, using a single ignition device, the simultaneous unlocking of the guide rail drill bit assembly clamping component 1 and the guide rail support and drill rod limiting component 2 is achieved, making the system more compact and efficient.

[0025] The guide rail support and drill rod limiting assembly 2 combines the functions of guide rail support and drill rod limiting by sharing a single bracket, thereby reducing the system weight. The support component lifts the middle of the guide rail, reducing deformation caused by excessive guide rail length and decreasing vibration amplitude. The support assembly is equipped with pulleys to reduce resistance to guide rail movement. The limiting component presses down the drill rod; through the cooperation of the two-drill structure of the drill rod 5 and the tensioning component, the drill rod is limited, reducing vibration amplitude.

[0026] like Figure 4 As shown, the guide rail drill assembly clamping component 1 includes a clamping seat 1-1, a separating nut 1-2, a clamping rod 1-3, a guide rail connector 1-4, an impact drill connector 1-5, a limiting cylinder 1-6, a spherical pad 1-7, a clamping nut 1-8, a support spring 1-9, a sleeve 1-10, a rope end 1-11, and inflection points 1-12 and 1-13 on the linkage rope seat.

[0027] like Figure 4 , Figure 5 As shown, a release nut 1-2 is installed on the clamping seat 1-1. The guide rail connector 1-4 and the impact drill connector 1-5 are connected and clamped onto the clamping seat 1-1 via the clamping rod 1-3. A sleeve 1-10 is installed on the impact drill connector 1-5, a pressure nut 1-8 is installed at the end of the clamping rod 1-3, a limiting cylinder 1-6 is installed on the clamping rod 1-3, and a spherical pad 1-7 is installed in the ball socket at the center of the limiting cylinder 1-6. The limiting cylinder 1-6 is located between the pressure nut 1-8 and the impact drill connector 1-5. A support spring 1-9 is installed between the limiting cylinder 1-6 and the impact drill connector 1-5. The protruding structure on the side of the limiting cylinder 1-6 extends from the opening on the side of the sleeve 1-10. A support plate is provided on one side of the clamping seat 1-1. A linkage rope seat inflection point 1-12 is provided at the end of the support plate. The inflection point 1-13 is located between the guide rail drill tool combination clamping assembly 1, the guide rail support and drill rod limiting assembly 2.

[0028] When the guide rail drill assembly clamping component 1 is in the clamped state, the limiting cylinder 1-6 and the impact drill connector 1-5 are connected to the rope head 1-11 of the linkage rope 3 through the protruding structure on the side, causing the support spring 1-9 to be compressed. The linkage rope 3 passes through the inflection points 1-12 and 1-13 in sequence and then connects to the guide rail support and drill rod limiting assembly 2. When unlocking, the release nut 1-2 detonates, releasing the clamping rod 1-3. The assembly of the limiting cylinder 1-6, the ball pad 1-7, the clamping nut 1-8, and the clamping rod 1-3, driven by the support spring 1-9, springs up to the top of the sleeve 1-10, thereby releasing the guide rail connector 1-4 and the impact drill connector 1-5. After the limiting cylinder 1-6 springs up, the rope head 1-11 is released, and the linkage rope is pulled away into the limiting hole at the inflection point 1-12 on the linkage rope seat.

[0029] like Figure 6 As shown, the guide rail support and drill rod limiting assembly 2 includes a limiting seat 2-1, a double screw 2-2, a guide rail support frame 2-3, a pulley shaft 2-4, a pulley 2-5, a rotating arm torsion spring assembly 2-6, a crank torsion spring assembly 2-8, a tilting arm 2-10, a movable pressure plate 2-11, an adjusting pin 2-12, and a fixed pressure plate 2-13; like Figure 6 , Figure 7 As shown, one end of the twin screw 2-2 is mounted on the limiting seat 2-1, and the other end is connected to the guide rail support frame 2-3. By rotating the twin screw 2-2, the guide rail support frame 2-3 can be raised or lowered, thereby controlling the support position of the guide rail. After proper adjustment, the twin screw 2-2 is tightened with two nuts. Two pulleys 2-5 are mounted on the guide rail support frame 2-3. There is a large gap between the pulleys 2-5 and the pulley shafts 2-4, and solid lubrication is applied to ensure smooth pulley rolling.

[0030] A torsion spring assembly 2-6 (including a torsion spring and a torsion spring fixing shaft) is installed on the limiting seat 2-1. A tilting arm 2-10 is installed on the torsion spring shaft 2-7, and the torsion spring assembly 2-6 drives the tilting arm 2-10 to tilt. A movable pressure plate 2-11, an adjusting pin 2-12, and a fixed pressure plate 2-13 are installed on the tilting arm 2-10 to limit the drill pipe position. A crank torsion spring assembly 2-8 (including a torsion spring and a torsion spring fixing shaft) is installed on the limiting seat 2-1. A crank 2-14 is installed on the crank torsion spring shaft 2-9, and the crank torsion spring assembly 2-8 drives the crank 2-14 to tilt. The crank 2-14 pushes the rope head 2-15 to move, thereby realizing the action of pulling the linkage rope 3 away from the clamping position of the guide rail drill tool assembly clamping assembly 1.

[0031] The release method is as follows: Clamping assembly a) Rail drill bit clamping The function of the guide rail drill assembly clamping component 1 is to clamp the guide rail and the impact drill. The clamping seat 1-1 is fixedly connected to the aircraft cabin panel, the guide rail connector 1-4 is fixedly connected to the drill guide rail, and the impact drill connector 1-5 is fixedly connected to the impact drill. The release nut 1-2 is installed on the clamping seat 1-1. During clamping, the clamping rod 1-3 is screwed into the threads of the release nut through the threaded sections of the guide rail connector 1-4 and the impact drill connector 1-5. The limiting cylinder 1-6 and the spherical washer 1-7 are installed, and the support spring 1-9 is placed inside the limiting cylinder 1-6. Clamping force is applied by tightening the clamping nut 1-8. When installing the limiting cylinder 1-6, the end of the linkage rope is installed in the groove of the limiting cylinder. After the linkage clamping device is assembled, the tension of the linkage rope is adjusted by adjusting the inflection point height.

[0032] b) Guide rail support A double screw 2-2 is installed on the limiting seat 2-1. Both ends of this part are threaded, and the other end connects to the guide rail support frame 2-3. By rotating the double screw 2-2, the guide rail support frame 2-3 can be raised or lowered to ensure the guide rail is lifted to a certain height, thus reducing the amplitude of guide rail vibration. After proper adjustment, the double screw 2-2 is tightened using two nuts. Two pulleys 2-5 are installed on the guide rail support frame 2-3. There is a large gap between the pulleys 2-5 and the pulley shafts 2-4, and solid lubrication is applied to ensure smooth pulley rolling and reduce the resistance to guide rail movement after unlocking.

[0033] c) Drill pipe limiting The limit seat 2-1 is equipped with a swing arm torsion spring assembly 2-6 and a crank torsion spring assembly 2-8. A tilting arm 2-10 is mounted on the swing arm torsion spring shaft 2-7, and a crank 2-14 is mounted on the crank torsion spring shaft 2-9. In the clamped state, one end of the crank 2-14 is pulled by the linkage rope, and the other end presses against the tilting arm 2-10. The torque provided by the linkage rope tension should be greater than the torque required to tilt the crank 2-14. The tilting arm 2-10 is equipped with a movable pressure plate 2-11, an adjusting pin 2-12, and a fixed pressure plate 2-13. The position of the movable pressure plate 2-11 is adjusted by the adjusting pin 2-12 to press down the drill rod, thereby limiting the drill rod position. After the position is properly adjusted, the adjusting pin is tightened to secure it.

[0034] Unlocking of the guide rail drill assembly clamping component: The release nut 1-2 detonates, releasing the clamping rod 1-3. The assembly of the limiting cylinder 1-6, spherical washer 1-7, clamping nut 1-8, and clamping rod 1-3, driven by the support spring 1-9, springs up to the top of the sleeve 1-10, thereby releasing the guide rail connector 1-4 and the impact drill connector 1-5. After the limiting cylinder 1-6 springs up, the rope end 1-11 is released, and the linkage rope is pulled into the limiting hole at the inflection point 1-12 on the linkage rope seat.

[0035] Unlocking of guide rail support and drill pipe limiting components: After the linkage rope head 1-11, fixed to the guide rail drill assembly clamping component 1, is released, the linkage rope 3 slackens, the tension disappears, and the crank torsion spring assembly 2-8 drives the crank 2-14 to rotate. The crank 2-14 pushes the rope head 2-15 to move, thereby realizing the action of pulling the linkage rope 3 away from the clamping position of the guide rail drill assembly clamping component 1. The rotation of the crank 2-14 releases the constraint on the rotating arm 2-10. Driven by the rotating arm torsion spring assembly 2-8, the rotating arm 2-10 rotates, releasing the constraint on the drill pipe 5, and at the same time realizing the avoidance of the movement space of the impact drill 6.

[0036] The parts of this invention not described in detail are well-known to those skilled in the art.
