[0032] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0033] Embodiment 1:

[0034] Please combine Figure 1 , Figure 2 , Figure 3 , Figure 8 and Fig. 9A rock sampling system for cavern surrounding rock excavation in this embodiment includes a bottom plate 1, a through opening 2 is opened in the middle of the bottom plate 1, a support frame 3 is fixedly connected to the top of the bottom plate 1, a storage mechanism located inside the support frame 3 is installed on the top of the bottom plate 1, an electric telescopic rod 4 is fixedly connected to the support frame 3, a motor 5 is installed on the output shaft of the electric telescopic rod 4, a connecting plate 6 is provided below the motor 5, the output shaft of the motor 5 is rotatably connected to the connecting plate 6, a gear 2 9 is sleeved on the output shaft of the motor 5, and a mounting cylinder 7 is rotatably installed on the connecting plate 6, The outside of the mounting tube 7 is fixedly sleeved with a gear 1 8 meshing with the gear 2 9, the bottom end of the mounting tube 7 is mounted with an extension tube 58, the bottom end of the extension tube 58 is mounted with a sampling tube 10, the bottom end of the sampling tube 10 is mounted with a sampling drill 11, the inner bottom end of the sampling tube 10 is provided with an annular groove 13, the inside of the sampling tube 10 and the top of the annular groove 13 is fixedly connected with an inner tube 14, the inner tube 14 is symmetrically provided with a sliding opening 27, the inside of the sampling tube 10 is provided with a sampling cutting mechanism, and the top end of the support frame 3 is provided with a discharge assembly extending to the inside of the sampling tube 10;

[0035] When the staff takes rock samples from the surrounding rock of the cavern, they first move the device into the cavern. In order to sample the surrounding rock, they first connect the installation tube 7 with the sampling tube 10. When it is necessary to increase the sampling depth, one or more extension tubes 58 are installed at the bottom of the installation tube 7, and the last extension tube 58 is connected to the sampling tube 10, so that the rock sampling depth can be extended. Since the rock is not cut off during the sampling process, the length of the sampled rock is relatively long, which will cause inconvenience in discharging during the removal process. At the same time, the weight of the rock is heavy when it is taken out as a whole, which will increase the difficulty of taking out the rock. Therefore, the design of the sampling cutting mechanism can cut the sampled rock, which is convenient for shortening the length of rock removal and reducing the weight of the rock, thereby providing convenience for rock discharging.

[0036] By starting the electric telescopic rod 14, the electric telescopic rod 14 drives the motor 15, the connecting plate 6, the installation tube 7, the extension tube 58, the sampling tube 10 and the sampling drill bit 11 to move downward. When the sampling drill bit 11 contacts the bottom of the cave, the motor 15 is started, and the motor 15 drives the gear 29 to rotate. Through the meshing connection relationship between the gear 29 and the gear 18, the gear 18 rotates, and the gear 18 drives the sampling tube 10 to rotate. As the sampling tube 10 moves downward, the sampling tube 10 drives the sampling drill bit 11 to drill the surrounding rock of the cave, so that the rock to be sampled enters the interior of the inner tube 14. When the connecting plate 6 moves down to the inside of the through hole 2, the electric telescopic rod 1 4 is stopped, and then the discharge assembly is controlled to move, so that the suspending discharge mechanism drives the clamping unit to move down, so that the moving seat 31 moves to the bottom end of the sliding mouth 27, and then the electric telescopic rod 2 41 is started, and the electric telescopic rod 2 41 will drive the limit plate 60 to move down, so that the limit plate 60 contacts the top end of the sampling tube 10, so that when the sampling tube 10 drives the moving seat 31 to rotate synchronously during the rotation process, the suspension rope 49 can be prevented from twisting above the limit plate 60 and becoming tangled, thereby effectively providing convenience for subsequent rock material extraction;

[0037] Then, the sampling and cutting mechanism is activated. While the motor 5 continues to work, the mounting tube 7 and the sampling tube 10 will rotate synchronously, thereby realizing the synchronous rotation of the sampling and cutting mechanism, so that the sampling and cutting mechanism can perform circular cutting on the rock inside the sampling tube 10, thereby disconnecting the rock and effectively avoiding overall material extraction, thereby facilitating rock extraction. After the rock is cut off, the clamping unit is controlled to operate, so as to clamp the cut rock, and cooperate with the suspension discharge mechanism to take out the cut rock. At the same time, cooperate with the design of the placement mechanism to facilitate the collection of the taken rock in sections, thereby facilitating effective multi-segment sampling of the rock.

[0038] The discharging assembly includes a suspension discharging mechanism located inside the sampling cylinder 10 and a clamping unit located above the sampling cutting mechanism. The clamping unit includes a lifting ring 28 sleeved on the outer wall of the inner cylinder 14. A rotating cylinder 29 is rotatably installed at the bottom end of the lifting ring 28. The rotating cylinder 29 is sleeved on the outer wall of the sampling cylinder 10. The rotating cylinder 29 is a T-shaped structure. A receiving groove 30 is opened at the bottom end of the rotating cylinder 29. A movable seat 31 that penetrates the inner wall of the rotating cylinder 29 and slides inside the sliding mouth 27 is symmetrically inserted inside the receiving groove 30. The movable seat 31 is elastically connected to the receiving groove 30. A clamping plate 32 is fixedly connected to the side where the two movable seats 31 are close to each other. A bevel 33 is provided on the side where the two movable seats 31 are far away from each other. A pushing piece is symmetrically provided on the outside of the rotating cylinder 29. The pushing piece includes a fixed plate 34 fixedly connected to the outer wall of the rotating cylinder 29. An electric push rod 35 is symmetrically installed at the bottom end of the fixed plate 34. The electric push rod The second output shaft 35 is connected to a trapezoidal push block 36 extending into the interior of the accommodating groove 30, and the trapezoidal push block 36 is in sliding contact with the second hypotenuse 33. It should be noted here that moving blocks are symmetrically arranged on both sides of the moving seat 31, and the inner wall of the accommodating groove 30 is provided with a moving groove slidably connected to the moving block, and the moving block and the moving groove are connected by a spring. The inner walls of the mounting cylinder 7 and the extension tube 58 are symmetrically provided with a slide groove 12, and the inner wall of the sampling cylinder 10 is provided with a slide groove 15 located above the accommodating groove 30 and connected to the slide groove 12. The outer wall bottom of the rotating cylinder 29 is symmetrically fixed with a sliding plate 37, and the sliding plate 37 slides inside the slide groove 15 and the slide groove 12. It should be noted here that a T-shaped joint is provided at the top of the rotating cylinder 29, and a T-shaped ring groove rotatably connected to the T-shaped joint is provided at the bottom end of the lifting ring 28, and a ball is embedded in the T-shaped joint. The design of the ball can reduce friction.

[0039] When the rock is cut, the electric push rod 2 35 is started, and the electric push rod 2 35 will drive the trapezoidal push block 36 to move downward. The trapezoidal push block 36 will slide on the bevel 2 33 during the downward movement, and then push the moving seat 31 to slide on the inner wall of the rotating cylinder 29, so that the moving seat 31 drives the clamping plate 32 to move, which is convenient for adjusting the distance between the two clamping plates 32, convenient for clamping the cut rock, and convenient for removing the rock. This design makes it easy for the sampling cylinder 10 to drive the rotating cylinder 29 to rotate synchronously during the rotation process. Through the rotational connection relationship between the rotating cylinder 29 and the lifting ring 28, the rotating cylinder 29 can be prevented from driving the lifting ring 28 to rotate synchronously.

[0040] The sampling and cutting mechanism includes a communication port 16 symmetrically opened at the bottom end of the inner wall of the sampling tube 10, a slide plate 18 penetrating the inside of the communication port 16 is slidably installed on the inner wall of the annular groove 13, a cutting knife 19 is fixedly connected to the two slide plates 18 on the side close to each other, and a bevel 20 is provided on the two slide plates 18 on the side away from each other. A sliding port 24 is opened on each of the two slide plates 18, and a stabilizing rod 25 sliding inside the sliding port 24 is fixedly connected to the inner wall of the annular groove 13, and the side wall of the sliding port 24 is connected to the stabilizing rod 25 by a spring 26. A pusher connected to the two slides 18 is provided inside, and the pusher includes a push ring seat 21 which is slidably sleeved on the outer wall of the inner cylinder 14 and located between the slide 18 and the rotating cylinder 29. A push rod 23 which is in rolling contact with the bevel 20 is symmetrically installed at the bottom end of the push ring seat 21. It should be noted here that a roller is provided at the bottom end of the push rod 23 to reduce the friction generated when the push slide 18 moves. A fixed rod 22 is fixedly connected to one side of the push ring seat 21, and an electric push rod 17 connected to the fixed rod 22 is fixedly connected to the top end of the annular groove 13;

[0041] When the rock is sampled to a suitable depth, the electric push rod 17 is started, and the electric push rod 17 will drive the push ring seat 21 to move downward through the fixed rod 22, and the push ring seat 21 will slide down the inner wall of the inner tube 14, and the push ring seat 21 will drive the push rod 23 to move downward synchronously, and the push rod 23 will drive the roller to move downward, and the roller will move downward on the bevel 20, so that the slide plate 18 will be subjected to force to drive the sliding port 24 to move laterally on the stabilizing rod 25, and the spring 26 will generate elastic force, so that the two slide plates 18 drive the cutting knife 19 to approach each other, and the cutting depth of the cutting knife 19 to the rock can be adjusted. At the same time, during the rotation of the sampling tube 10, the cutting knife 19 is driven to rotate synchronously, so that the cutting knife 19 can cut the rock in an annular manner, cut the rock, and realize the segmented operation of the rock, so as to provide convenience for the later extraction of the rock.

[0042] The suspension discharging mechanism includes a groove 39 opened at the top of the support frame 3, a mounting plate 38 is fixedly connected to the top of the support frame 3, a connecting hole 43 connected to the groove 39 is opened on the mounting plate 38, and a through hole 42 connected to the groove 39 is symmetrically opened at the bottom end of the support frame 3, a support plate 45 is fixedly connected to the top of the mounting plate 38, a winding unit is provided on the support plate 45, and two suspension ropes 49 are connected to the winding unit. The suspension ropes 49 pass through the connecting hole 43 and the through hole 42 in sequence and are fixed to the top of the lifting ring 28. A stabilizer is provided at the bottom end of the mounting plate 38, and the stabilizer includes a fastening rod 40 fixedly connected to the bottom end of the mounting plate 38, pulleys 50 are rotatably installed at both ends of the fastening rod 40, and the suspension rope 49 slides on the outer wall of the pulley 50. An electric telescopic rod 2 41 is fixedly connected to the middle position of the bottom end of the fastening rod 40, and the output shaft of the electric telescopic rod 2 41 is connected to the limiting plate 60. The limit plate 60 is slidably sleeved on the outside of the two suspension ropes 49, and the limit plate 60 is in contact with the top of the sampling tube 10. The winding unit includes a rotating shaft 46 rotatably mounted on the support plate 45 and symmetrically arranged. Gear three 47 and winding wheels 48 are fixedly sleeved on the two rotating shafts 46. The two gears three 47 are meshingly connected, and the suspension rope 49 is wound around the outside of the winding wheels 48. A motor 2 44 connected to one of the rotating shafts 46 is installed on the support plate 45. The length of the fastening rod 40 is smaller than the diameter of the mounting tube 7 and the extension tube 58, and the long end of the fastening rod 40 is larger than the diameter of the inner tube 14. It should be noted here that the winding directions of the suspension rope 49 on the winding wheels 48 are opposite, so that when the two winding wheels 48 rotate in opposite directions, the rope collection or rope release operation of the suspension rope 49 can be realized synchronously, thereby effectively facilitating the suspension rope 49 to drive the lifting ring 28 to rise and fall;

[0043] After the clamping plate 32 clamps the rock, the motor 2 44 is started, and the motor 2 44 drives one of the winding wheels 48 and a gear 3 47 to rotate. Through the meshing connection relationship between the two gears 3 47, the other gear 3 47 is rotated in the opposite direction, so that the two winding wheels 48 rotate in opposite directions, so that the winding wheel 48 winds up the suspension rope 49, so that the suspension rope 49 pulls the lifting ring 28 to move upward, and the lifting ring 28 drives the rotating cylinder 29 to move upward, and the rotating cylinder 29 drives the moving seat 31 to move upward, so that the moving seat 31 slides upward on the inner wall of the sliding port 27, thereby driving the clamping plate 32 to move the lifting ring 28 upward. The rock moves upward, and at the same time, the rotating cylinder 29 drives the sliding plate 37 to slide upward in the second slide groove 15, and at the same time, the electric telescopic rod 241 drives the limit plate 60 to move upward, so as to avoid the limit plate 60 hindering the upward movement of the rock. When the rock moves into the extension tube 58, the sliding plate 37 moves into the slide groove 12 on the inner wall of the extension tube 58. When the rock moves into the installation cylinder 7, the sliding plate 37 moves into the slide groove 12 on the inner wall of the installation cylinder 7, effectively maintaining the stable upward movement of the rotating cylinder 29, improving the upward movement stability of the rock, and avoiding the rock from being blocked between the extension tube 58 and the installation cylinder 7. During the upward movement of the loading tube 7, collision occurs due to shaking, which effectively protects the sampled rock. As the winding wheel 48 continues to reel in the suspension rope 49, the sliding plate 37 is disengaged from the slide groove 12, and the clamping unit is disengaged from the inside of the installation tube 7, so that the rock moves upward on the top of the installation tube 7. When the clamping unit drives the rock to rise above the collecting seat 53, the motor 2 44 is stopped. At the same time, the design of the placement mechanism is coordinated to facilitate the separation and storage of the rocks, and the collection of the rocks is effectively realized. In the process of collecting the rocks, the staff will install the installation tube 7 and the extension tube 7. The long tube 58 is disconnected, and then the electric telescopic rod 4 is started, which will cause the electric telescopic rod 4 to drive the installation tube 7 to move up through the connecting plate 6, so that the installation tube 7 is close to the rotating disk 52. In this process, the extension tube 58 and the sampling tube 10 can be prevented from repeatedly rising and falling inside the surrounding rock. When it is necessary to increase the sampling depth, the staff will add an extension tube 58 to the top of the extension tube 58, and then the electric telescopic rod 4 will drive the installation tube 7 to move down, and make the installation tube 7 contact with the extension tube 58, and then realize the connection between the installation tube 7 and the extension tube 58, which effectively provides convenience for further sampling of the rock.

[0044] The implementation principle of a rock sampling system for cavern surrounding rock excavation in the embodiment of the present application is:

[0045] By starting the electric telescopic rod 14, the electric telescopic rod 14 drives the motor 15, the connection plate 6, the installation tube 7, the extension tube 58, the sampling tube 10 and the sampling drill bit 11 to move downward. When the sampling drill bit 11 contacts the bottom of the cave, the motor 15 is started, and the motor 15 drives the gear 29 to rotate. Through the meshing connection relationship between the gear 29 and the gear 18, the gear 18 is rotated, and the gear 8 drives the sampling tube 10 to rotate. As the sampling tube 10 moves downward, the sampling tube 10 drives the sampling drill bit 11 to drill the surrounding rock of the cave, so that the rock to be sampled enters the interior of the inner tube 14. When the connection plate 6 moves down to the interior of the through opening 2, the electric telescopic rod 14 stops working;

[0046] Then start the motor 2 44, the motor 2 44 will drive one of the winding wheels 48 and a gear 3 47 to rotate, and through the meshing connection relationship between the two gears 3 47, the other gear 3 47 will rotate in the opposite direction, so that the two winding wheels 48 rotate in opposite directions, so that the winding wheel 48 can release the suspension rope 49, so that the suspension rope 49 can drive the lifting ring 28 and the rotating cylinder 29 to move downward synchronously. When the rotating cylinder 29 moves to the inside of the installation cylinder 7, the sliding plate 37 on the rotating cylinder 29 will slide into the inside of the slide groove 12. As the suspension rope 49 continues to be released, The rotating cylinder 29 drives the moving seat 31 to move downward synchronously, so that the moving seat 31 moves to the inside of the sliding opening 27. When the moving seat 31 moves to the bottom of the sliding opening 27, the rope release work of the suspension rope 49 is stopped, and the electric telescopic rod 2 41 is started. The electric telescopic rod 2 41 will drive the limit plate 60 to move downward, so that the limit plate 60 contacts the top of the sampling cylinder 10, so that when the sampling cylinder 10 drives the moving seat 31 to rotate synchronously during the rotation process, the suspension rope 49 can be prevented from twisting above the limit plate 60 and becoming tangled, thereby effectively providing convenience for subsequent rock material collection;

[0047] Then, the electric push rod 17 is started, and the electric push rod 17 drives the push ring seat 21 to move downward through the fixed rod 22, and the push ring seat 21 slides down on the inner wall of the inner tube 14, and the push ring seat 21 drives the push rod 23 to move downward synchronously, and the push rod 23 drives the roller to move downward, and the roller moves downward on the bevel 20, so that the slide plate 18 is subjected to force to drive the slide port 24 to move horizontally on the stabilizing rod 25, and the spring 26 can generate elastic force, so that the two slide plates 18 drive the cutting knife 19 to approach each other, and the cutting depth of the cutting knife 19 to the rock can be adjusted. At the same time, the cutting knife 19 is driven to rotate synchronously during the rotation of the sampling tube 10, so that the cutting knife 19 can cut the rock in an annular manner, cut off the rock, and realize the segmented operation of the rock, so as to provide convenience for the later extraction of the rock;

[0048] The electric push rod 2 35 is started, and the electric push rod 2 35 drives the trapezoidal push block 36 to move downward. The trapezoidal push block 36 slides on the second bevel 33 during the downward movement, and then drives the moving seat 31 to slide on the inner wall of the rotating cylinder 29, so that the moving seat 31 drives the clamping plate 32 to move, so as to adjust the distance between the two clamping plates 32, facilitate the clamping of the cut rock, and provide convenience for taking out the rock;

[0049] After the clamping plate 32 clamps the rock, the motor 2 44 is started, and the motor 2 44 drives one of the winding wheels 48 and a gear 3 47 to rotate. Through the meshing connection relationship between the two gears 3 47, the other gear 3 47 is rotated in the opposite direction, so that the two winding wheels 48 rotate in opposite directions, so that the winding wheel 48 winds up the suspension rope 49, so that the suspension rope 49 pulls the lifting ring 28 to move upward, and the lifting ring 28 drives the rotating cylinder 29 to move upward, and the rotating cylinder 29 drives the moving seat 31 to move upward, so that the moving seat 31 slides upward on the inner wall of the sliding port 27, thereby driving the clamping plate 32 to move the lifting ring 28 upward. The rock moves upward, and at the same time, the rotating cylinder 29 drives the sliding plate 37 to slide upward in the second slide groove 15, and at the same time, the electric telescopic rod 241 drives the limit plate 60 to move upward, so as to avoid the limit plate 60 hindering the upward movement of the rock. When the rock moves into the extension tube 58, the sliding plate 37 moves into the slide groove 12 on the inner wall of the extension tube 58. When the rock moves into the installation cylinder 7, the sliding plate 37 moves into the slide groove 12 on the inner wall of the installation cylinder 7, effectively maintaining the stable upward movement of the rotating cylinder 29, improving the upward movement stability of the rock, and avoiding the rock from being blocked between the extension tube 58 and the installation cylinder 7. During the upward movement of the loading tube 7, collision occurs due to shaking, which effectively protects the sampled rock. As the winding wheel 48 continues to reel in the suspension rope 49, the sliding plate 37 is disengaged from the slide groove 12, and the clamping unit is disengaged from the inside of the installation tube 7, so that the rock moves upward on the top of the installation tube 7. When the clamping unit drives the rock to rise above the collecting seat 53, the motor 2 44 is stopped. At the same time, the design of the placement mechanism is coordinated to facilitate the separation and storage of the rocks, and the collection of the rocks is effectively realized. In the process of collecting the rocks, the staff will install the installation tube 7 and the extension tube 7. The long tube 58 is disconnected, and then the electric telescopic rod 4 is started, which will cause the electric telescopic rod 4 to drive the installation tube 7 to move up through the connecting plate 6, so that the installation tube 7 is close to the rotating disk 52. In this process, the extension tube 58 and the sampling tube 10 can be prevented from repeatedly rising and falling inside the surrounding rock. When it is necessary to increase the sampling depth, the staff will add an extension tube 58 to the top of the extension tube 58, and then the electric telescopic rod 4 will drive the installation tube 7 to move down, and make the installation tube 7 contact with the extension tube 58, and then realize the connection between the installation tube 7 and the extension tube 58, which effectively provides convenience for further sampling of the rock.

It should be noted here that during the rock collection process, the suspension rope 49 and the electric telescopic rod 2 41 will pass through the inside of the arc groove 59, so as to facilitate the rock collection work;

[0052] When the rock moves to the top of the collecting seat 53, the motor 3 56 is started, and the motor 3 56 drives the worm 57 to rotate. Through the meshing connection between the worm 57 and the worm wheel 55, the worm wheel 55 is rotated, and the worm wheel 55 drives the rotating shaft 51 to rotate, and the rotating shaft 51 drives the rotating disk 52 to rotate, and the rotating disk 52 drives the collecting seat 53 to rotate, so that the collecting seat 53 moves to the bottom of the rock, and the motor 3 56 is stopped, and the motor 2 44 is started again to realize the rope release operation of the suspension rope 49, so that the rotating cylinder 29 is close to the collecting seat 53, and the distance between the rotating cylinder 29 and the collecting seat 53 is reduced, which effectively shortens the distance for the rock to fall. Then the motor 2 44 is stopped, and the electric push rod 2 35 is started to move the trapezoidal push block 36 upward, and then under the action of the spring force, the two moving seats 31 are moved away from each other, so that the clamping plate 32 can disconnect the clamping of the rock, and the rock can fall onto the placement plate 54 inside the collecting seat 53, so as to realize the collection of the rock after sampling.
