[0020] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0023] like Figure 1 and Figure 2As shown, the present invention proposes a green and energy-saving high-pressure device for the synthesis of superhard materials, including six groups of hinge beams 1 distributed in the upper, lower, left, right, front and rear directions. The six groups of hinge beams 1 are arranged in a "spherical" layout. The outer side of each group of hinge beams 1 is fixed with four groups of hinge ears 2 in a circular array. The two adjacent groups of hinge ears 2 are docked together, and the hinge ears 2 can connect the six groups of hinge beams 1 together, and a pin is inserted into the two docked groups of hinge ears 2 to fix the hinge ears 2. A hydraulic cylinder 3 is installed inside each group of hinge beams 1, and a top hammer 4 is installed at the end close to each group of hydraulic cylinders 3. When the hydraulic cylinder 3 is in operation, it can drive the top hammer 4 to move, thereby performing high-pressure synthesis of sealing media such as talc. It should be noted that the hydraulic cylinder 3 and the top hammer 4 are both existing technologies, which are conventional technologies in hinged six-sided top hydraulic presses and will not be elaborated in detail.

[0024] As an implementation method, Figure 3 - Figure 7 As shown, this embodiment also includes a metal rod 5 fixedly connected to the outside of multiple groups of top hammers 4. In this embodiment, only one group of metal rods 5 is drawn, but it should be noted that a metal rod 5 and other components cooperating with the metal rod 5 are provided on the outside of each group of top hammers 4. When the hydraulic cylinder 3 drives the top hammer 4 to run smoothly, the metal rod 5 will move synchronously with the top hammer 4. The end of the metal rod 5 away from the top hammer 4 is fixedly connected to a traction rope 6. The movement of the metal rod 5 will drive the traction rope 6 to move, applying a pulling force to the traction rope 6. The end of the hinge beam 1 away from the top hammer 4 is fixedly connected to a connecting rod 8. The outer side of the connecting rod 8 is rotatably connected to the limit roller 7, and the connecting rod 8 supports the limit roller 7. The end of the traction rope 6 away from the metal rod 5 is wrapped around the outside of the limiting roller 7. When the traction rope 6 is pulled by the metal rod 5, the traction rope 6 will drive the limiting roller 7 to rotate, thereby gradually releasing the length of the traction rope 6. A coil spring 9 is fixed to the outside of the connecting rod 8. The end of the coil spring 9 away from the connecting rod 8 is fixed to the bottom end of the limiting roller 7, and when the limiting roller 7 rotates, the limiting roller 7 will also cooperate with the connecting rod 8 to drive the coil spring 9 to deform and generate elastic potential energy. When the hydraulic cylinder 3 drives the top hammer 4 to reset, the top hammer 4 synchronously drives the metal rod 5 to reset. At this time, the coil spring 9 can release the elastic potential energy, drive the limiting roller 7 to rotate in the opposite direction, and make the traction rope 6 wrapped around the outside of the limiting roller 7 again.

[0025] Further, such as Figure 5 、 Figure 6 and Figure 7As shown, this embodiment also includes a ring 10 fixed to one end of the hinge beam 1 near the limiting roller 7. The hinge beam 1 supports the ring 10. A plurality of groups of latch teeth 11 are fixed to the inner side of the ring 10. A centrifugal latching mechanism is provided at the top of the limiting roller 7 to cooperate with the latch teeth 11 to limit the instantaneous movement of the top hammer 4. When the top hammer 4 continues to squeeze the sealing medium such as phyllite, the centrifugal latching mechanism is in a stationary state. When the sealing medium such as phyllite suddenly breaks, the top hammer 4 will move instantly under the action of inertia. At this time, the top hammer 4 will pass The metal rod 5 and the traction rope 6 drive the limiting roller 7 to rotate instantaneously. The instantaneous rotation of the limiting roller 7 will drive the centrifugal engaging mechanism to operate instantaneously. The centrifugal engaging mechanism will quickly connect with the latching teeth 11 at this time, and will be blocked by the latching teeth 11 and cannot continue to operate. The limiting roller 7 is now stationary and cannot rotate under the action of the centrifugal engaging mechanism. When the limiting roller 7 is stationary, it will drive the top hammer 4 to be stationary through the traction rope 6 and the metal rod 5, thereby preventing the top hammer 4 from continuing to move, thereby preventing the top hammer 4 from colliding with each other and "exploding" and causing damage.

[0026] Furthermore, if Figure 6 and Figure 7 As shown, the acceleration mechanism in this embodiment is connected to the centrifugal engaging mechanism, and is used to accelerate the speed of the centrifugal engaging mechanism engaging with the engaging teeth 11 when the centrifugal engaging mechanism is running. After the centrifugal engaging mechanism runs a certain distance, the acceleration mechanism will run instantly. The operation of the acceleration mechanism will fill the interior of the centrifugal engaging mechanism with gas, and the gas will compress the internal air of the centrifugal engaging mechanism, thereby accelerating the operation of the centrifugal engaging mechanism, so that it accelerates the connection between the centrifugal engaging mechanism and the engaging teeth 11, thereby shortening the time required for the centrifugal engaging mechanism to restrict the movement of the top hammer 4 under the action of inertia.

[0027] Among them, such as Figure 5 、 Figure 6 and Figure 7 As shown, the centrifugal engaging mechanism includes a centrifugal tube 12, a gravity ball 13, a pressure plate 14, a support rod 15, a clamping plate 16, a rotating shaft 17 and a compression spring 18. The centrifugal engaging mechanism is described in detail below: The centrifuge tube 12 is fixed to the top of the limiting roller 7. In the first state, when the limiting roller 7 rotates smoothly, the limiting roller 7 drives the centrifuge tube 12 to perform a smooth circular motion. The gravity ball 13 is arranged inside the centrifuge tube 12. The gravity ball 13 is located inside the centrifuge tube 12. Under the action of the centrifuge tube 12 performing a smooth circular motion, the centrifuge tube 12 is attached to the pressure plate 14 and is in a relatively static state. In the second state, when the limiting roller 7 is instantaneously rotated, the centrifuge tube 12 is moved in a relatively static state. Figure 6When the view angle rotates clockwise, the limiting roller 7 will instantaneously drive the centrifugal tube 12 to move, and the gravity ball 13 is not fixedly connected with the centrifugal tube 12, so that when the centrifugal tube 12 moves at a speed that is too fast, the friction force between the centrifugal tube 12 and the gravity ball 13 acts for a time that is too short, and cannot break through the static friction force impulse threshold, so that the centrifugal tube 12 will not move in the same direction with the gravity ball 13, the pressure plate 14 is slidingly connected to the inner wall of the centrifugal tube 12, and under the inertial action of the centrifugal tube 12, the gravity ball 13 will move towards the pressure plate 14, and the gravity ball 13 extrudes the pressure plate 14 at this time, the supporting rod 15 is fixedly connected to one end of the pressure plate 14 away from the gravity ball 13, and the supporting rod 15 penetrates through the centrifugal tube 12 and extends to the outside of the centrifugal tube 12, so that the pressure plate 14 will drive the supporting rod 15 to move, the top end of the limiting roller 7 is provided with a clamping plate 16, the inside of the clamping plate 16 is fixedly connected with a rotating shaft 17, the rotating shaft 17 is rotationally connected with the top end of the limiting roller 7, the supporting rod 15 is hingedly connected with the clamping plate 16, the supporting rod 15 moves to drive the clamping plate 16 to swing along the rotating shaft 17, and the rotating shaft 17 also rotates at the top end of the limiting roller 7 along with the clamping plate 16, and after the clamping plate 16 swings for a distance, the clamping plate 16 is attached to the clamping tooth 11, at this time, the clamping tooth 11 and the clamping plate 16 are clamped together, so that the limiting roller 7 will not rotate, thereby limiting the position of the top hammer 4, the compression spring 18 is fixedly connected between the inner wall of the centrifugal tube 12 and the pressure plate 14, and when the pressure plate 14 moves, the pressure plate 14 also extrudes the compression spring 18, so that the compression spring 18 is deformed to generate elastic potential energy, after the inertial action of the top hammer 4 ends, the limiting roller 7 is in a completely static state, and the compression spring 18 releases the elastic potential energy to pull the clamping plate 16 to swing reversely and reset, and to be separated from the clamping of the clamping tooth 11, it should be noted that the size of the centrifugal tube 12 and the gravity ball 13 can be determined according to actual conditions, and the elastic potential energy of the compression spring 18 can only pull the clamping plate 16 to reset and drive the gravity ball 13 to generate slight inertia when the centrifugal tube 12 runs stably.

[0028] In addition, as shown in Figure 6 and Figure 7 , the acceleration mechanism includes a sealed box 19, a metal elastic plate 20 and a gas conveying pipe 21, and the acceleration mechanism will be specifically described as follows. The sealing box 19 is fixedly connected to the top of the limiting roller 7, and the interior of the sealing box 19 is filled with sodium azide. The metal elastic plate 20 is fixedly connected to the outside of the rotating shaft 17 located inside the sealing box 19. When the card plate 16 swings and drives the rotating shaft 17 to rotate, the rotating shaft 17 will synchronously drive the metal elastic plate 20 to make a circular motion along the rotating shaft 17. After the rotating shaft 17 rotates to a certain number of circles, the inner wall of the sealing box 19 is provided with multiple sets of friction teeth, and the metal elastic plate 20 will contact the friction teeth. At this time, the metal elastic plate 20 and the friction teeth will produce small sparks, and the sparks will ignite the sodium azide in the sealing box 19, and the reaction of the sodium azide will cause the metal elastic plate 20 to ignite. It should be completed within 30 milliseconds to generate a large amount of nitrogen. The two ends of the gas pipe 21 are respectively fixed to the inside of the sealing box 19 and the centrifuge tube 12, and the end of the gas pipe 21 close to the centrifuge tube 12 is located on the side of the pressure plate 14 close to the gravity ball 13. The nitrogen will be quickly transmitted to the inside of the centrifuge tube 12 through the gas pipe 21. The gravity ball 13 and the pressure plate 14 inside the centrifuge tube 12 are squeezed by the nitrogen at this time, and will accelerate the operation, thereby increasing the swing speed of the card plate 16. It should be noted that the gas generated by sodium azide is mainly inert nitrogen, which is non-toxic and non-flammable, and meets the extreme requirements of the safety device for instantaneous action.

[0029] Further, such as Figure 7 As shown, the gravity ball 13 is of "spherical" design, and the diameter of the gravity ball 13 is adapted to the size of the inner wall of the centrifuge tube 12, which can ensure that the gravity ball 13 will not shake randomly when inside the centrifuge tube 12, and can only move along a specified route. The inner wall of the centrifuge tube 12 and the pressure plate 14 are both made of rubber. The rubber material can prevent the pressure plate 14 from moving slightly inside the centrifuge tube 12 and generating sparks.

[0030] As an implementation method, Figure 8 - Figure 11As shown, the end of the hydraulic cylinder 3 away from the top hammer 4 is fixedly connected to a pressure relief pipe 22, and a semicircular plate 1 23 is fixedly connected to the inner wall of the pressure relief pipe 22, and a semicircular plate 24 is slidably connected to the inner wall of the pressure relief pipe 22. In the initial state, the combined cross-section of the semicircular plate 1 23 and the semicircular plate 24 is "circular", and the liquid inside the hydraulic cylinder 3 cannot pass through the semicircular plate 1 23 and the semicircular plate 24. The end of the semicircular plate 24 away from the hydraulic cylinder 3 is fixedly connected to two groups of limiting rods 1 25, and the ends of the two groups of limiting rods 1 25 away from the semicircular plate 24 are fixedly connected to a horizontal plate 1 26. The outer side of the limiting rod 1 25 is slidably connected to a horizontal plate 27, and the horizontal plate 27 is fixedly connected to the semicircular plate 1 23. The horizontal plate 27 supports the limiting rod 1 25, and the limiting rod Rod 1 25 can support semicircular plate 24. Two groups of tension springs 28 are fixed between horizontal plate 27 and horizontal plate 1 26. Metal rod 2 29 is fixed to the outside of metal rod 1 5. When metal rod 1 5 moves, metal rod 1 5 will synchronously drive metal rod 2 29 to move. A traction rope 2 30 is provided at the end of metal rod 2 29 away from metal rod 1 5. An adjustment mechanism is provided between metal rod 2 29 and traction rope 2 30. The adjustment mechanism is used to adjust the tension of traction rope 2 30. The traction rope 2 30 can be adjusted to an appropriate tension through the adjustment mechanism. The appropriate tension depends on the actual situation. When the normal top hammer 4 is sealed with high-pressure pyrophyllite or other sealing media, the traction rope 2 30 will not be in a completely straight state. When the top hammer 4 is suddenly displaced, it indicates that the sealing medium such as phyllite is broken. The moving distance of the metal rod 1 5 continues to increase at this time, and the traction rope 2 30 is in a taut state. The end of the traction rope 2 30 away from the metal rod 2 29 is fixedly connected to the metal rod 3 31. The traction rope 2 30 will pull the metal rod 31. The periphery of the metal rod 31 is provided with a blocking mechanism, which is used to limit the displacement of the semicircular plate 2 24. When the metal rod 31 is subjected to force, it will drive the blocking mechanism to operate. The blocking mechanism will then end the limitation of the semicircular plate 2 24, and the liquid inside the pressure relief pipe 22 will exert pressure on the semicircular plate 2 24. Under the pressure of the liquid, the semicircular plate 2 24 will drive the limiting rod 1 25 to move along the inside of the horizontal plate 2 27. When the semicircular plate 1 23 is moved and the fitting with the semicircular plate 1 23 is completed, the liquid can pass through the semicircular plate 2 24, thereby releasing the liquid pressure inside the hydraulic cylinder 3, thereby avoiding excessive pressure, which causes the aggravated wear of the card plate 16 and the card tooth 11 when fitting, and improving the service life of the device. When the semicircular plate 24 drives the limit rod 1 25 to move, the limit rod 1 25 also drives the cross plate 1 26 to move. At this time, the cross plate 1 26 cooperates with the cross plate 2 27 to apply tension to the tension spring 28, causing the tension spring 28 to deform and generate elastic potential energy. When the hydraulic cylinder 3 stops running and drives the top hammer 4 to reset, the tension spring 28 will release the elastic potential energy, pulling the cross plate 1 26 to move in the opposite direction to reset. The cross plate 1 26 then drives the semicircular plate 2 24 to reset through the limit rod 1 25.To make the semicircular plate 24 and the semicircular plate 1 23 fit together again, it should be noted that under normal working conditions when the hydraulic cylinder 3 does not add liquid to the inner cavity, the elastic potential energy released by the tension spring 28 is sufficient to pull the horizontal plate 1 26 back to its original position, ensuring that the semicircular plate 24 and the semicircular plate 1 23 fit together. However, under working conditions when the hydraulic cylinder 3 continues to add liquid to the inner cavity, the pressure exerted by the liquid on the semicircular plate 24 cannot be overcome by the tension spring 28, causing deformation. The hydraulic cylinder 3 is a well-known and mature device that generates hydraulic potential energy by adding liquid to the inner cavity to cause piston motion.

[0031] Further, such as Figure 9 and Figure 10 As shown, the blocking mechanism includes a side arc plate 32, a baffle 33, two sets of limiting rods 34, a receiving box 35 and a compression spring 36. The blocking mechanism is described in detail below: The side arc plate 32 is fixedly connected to the metal rod 31. When the metal rod 31 moves, it will pull the side arc plate 32 to move. The baffle 33 is fixedly connected to the end of the side arc plate 32 away from the metal rod 31. The baffle 33 passes through the pressure relief pipe 22 and fits the semicircular plate 24. The movement of the side arc plate 32 will drive the baffle 33 to move. In the initial state, the baffle 33 blocks the moving direction of the semicircular plate 24. When the baffle 33 moves, the movement of the semicircular plate 24 by the baffle 33 ends, and the semicircular plate 24 can move. The two sets of the limiting rods 2 34 are both fixedly connected to the outside of the pressure relief pipe 22, and the limiting rods 2 34 pass through the side arc plate 32. When the side arc plate 32 moves, it will move along the outside of the limiting rod 2 34. The receiving box 35 The second compression spring 36 is fixed to the outside of the pressure relief pipe 22, and the end of the second limiting rod 34 away from the pressure relief pipe 22 is fixed to the inner wall of the accommodating box 35. The second compression spring 36 is sleeved on the outside of the two groups of second limiting rods 34, and the two ends of the second compression spring 36 are fixed between the side arc plate 32 and the inner wall of the accommodating box 35. The movement of the side arc plate 32 will also cooperate with the accommodating box 35 to squeeze the second compression spring 36, causing the second compression spring 36 to deform and generate elastic potential energy. When the metal rod three 31 finishes pulling the side arc plate 32, the second compression spring 36 will release the elastic potential energy and push the baffle 33 to reset through the side arc plate 32, so that the baffle 33 blocks the moving route of the semicircular plate 24 again. It should be noted that the semicircular plate 24 needs to be reset first before the baffle 33 can be reset.

[0032] Furthermore, if Figure 11 As shown, the adjustment mechanism includes a screw 37 and an internal threaded tube 38. The adjustment mechanism is described in detail below: The screw 37 is fixed to one end of the metal rod 29 close to the traction rope 2 30, and the internal threaded tube 38 is threadedly connected to the outside of the screw 37. The traction rope 2 30 is fixed to the internal threaded tube 38. When extruding sealing media such as talc of different sizes, the traction rope 2 30 may need to be in different tightness states so that the pulling force can be transmitted to the metal rod 3 31 in time. When this embodiment is in use, the internal threaded tube 38 can be rotated in different directions along the outside of the screw 37. When the internal threaded tube 38 is rotated in different directions, the length of the internal threaded tube 38 located on the outside of the screw 37 can be adjusted, and then the traction rope 2 30 can be adjusted to a suitable tightness.

[0033] As an implementation method, Figure 10 As shown, the edges of the semicircular plate 1 23, the semicircular plate 24 and the baffle 33 are all made of rubber material, which is used to increase the sealing performance and avoid the leakage of liquid along the gaps.

[0034] In addition, if Figure 5 and Figure 8 As shown, the traction rope 1 6 and the traction rope 2 30 are aramid braided ropes, which are resistant to high temperatures and have high tensile strength, and are suitable for the scenarios required in this embodiment.

[0035] A green synthesis process for superhard materials, comprising the following steps: S1: When the hydraulic cylinder 3 is in operation, it can drive the top hammer 4 to move, thereby performing high-pressure synthesis on the sealing medium such as pyrophyllite. When the top hammer 4 continues to squeeze the sealing medium such as pyrophyllite, the centrifugal engaging mechanism is in a stationary state; S2: When the sealing medium such as pyrophyllite suddenly breaks, the top hammer 4 will move instantly under the action of inertia. At this time, the top hammer 4 will drive the limiting roller 7 to rotate instantly through the metal rod 5 and the traction rope 6. The instantaneous rotation of the limiting roller 7 will drive the centrifugal engaging mechanism to operate instantly. S3: The centrifugal engaging mechanism will quickly connect with the latching teeth 11 at this time, and will be blocked by the latching teeth 11 and cannot continue to run. The limiting roller 7 will be stationary and cannot rotate under the action of the centrifugal engaging mechanism. When the limiting roller 7 is stationary, it will drive the top hammer 4 to be stationary through the traction rope 6 and the metal rod 5, thus preventing the top hammer 4 from continuing to move, causing the top hammers 4 to collide with each other and "explode", resulting in damage.

[0036] In this embodiment, a sealing medium such as phyllite is placed at the center position squeezed by multiple groups of top hammers 4, and the hydraulic cylinder 3 is started. The hydraulic cylinder 3 drives the top hammer 4 to squeeze the sealing medium such as phyllite. When the hydraulic cylinder 3 drives the top hammer 4 to operate smoothly, the metal rod 5 will move synchronously with the top hammer 4. The movement of the metal rod 5 will drive the traction rope 6 to move, applying a pulling force to the traction rope 6. When the traction rope 6 is pulled by the metal rod 5, the traction rope 6 will drive the limiting roller 7 to rotate, thereby gradually releasing the length of the traction rope 6, and when the limiting roller 7 rotates, the limiting roller 7 will also cooperate with the connecting rod 8 to drive the coil spring 9 to deform and generate elastic potential energy. When the limiting roller 7 rotates smoothly, the limiting roller 7 drives the centrifuge tube 12 to perform a circular motion smoothly, and the weight The gravity ball 13 is located inside the centrifuge tube 12. Under the action of the centrifuge tube 12 making a smooth circular motion, it is attached to the pressure plate 14 and is in a relatively static state. When the limit roller 7 rotates instantly, the limit roller 7 will instantly drive the centrifuge tube 12 to move, but the gravity ball 13 is not fixed to the centrifuge tube 12. Therefore, the centrifuge tube 12 moves too fast, and the friction between the centrifuge tube 12 and the gravity ball 13 acts for too short a time, which cannot break through the static friction impulse threshold. The centrifuge tube 12 will not move in the same direction as the gravity ball 13, and the gravity ball 13 will move toward the pressure plate 14 under the inertia of the centrifuge tube 12. The gravity ball 13 squeezes the pressure plate 14 at this time, and the pressure plate 14 is compressed to drive the support rod 15 to move, and the support rod 15 The movement will drive the card plate 16 to swing along the rotating shaft 17, and the rotating shaft 17 will also follow the card plate 16 to rotate at the top of the limiting roller 7. After the card plate 16 swings a distance, it will fit with the card tooth 11. At this time, the card tooth 11 and the card plate 16 are engaged together, and the limiting roller 7 will not rotate, thereby limiting the position of the top hammer 4. When the pressure plate 14 moves, the pressure plate 14 will also squeeze the compression spring 18, causing the compression spring 18 to deform and generate elastic potential energy. When the card plate 16 swings and drives the rotating shaft 17 to rotate, the rotating shaft 17 will synchronously drive the metal elastic plate 20 to make a circular motion along the rotating shaft 17. After the rotating shaft 17 rotates a certain number of circles, the metal elastic plate 20 will contact the friction teeth, and the metal elastic plate 20 and the friction teeth will produce small sparks at this time, and Sparks will ignite the sodium azide in the sealed box 19. The reaction of sodium azide is completed within 30 milliseconds, generating a large amount of nitrogen. The nitrogen will be quickly transmitted to the inside of the centrifuge tube 12 through the gas pipe 21. The gravity ball 13 and the pressure plate 14 inside the centrifuge tube 12 will be squeezed by the nitrogen at this time, and will accelerate their operation, thereby increasing the swing speed of the card plate 16. When the hydraulic cylinder 3 drives the top hammer 4 to reset, the top hammer 4 synchronously drives the metal rod 5 to reset. At this time, the coil spring 9 can release its elastic potential energy, driving the limit roller 7 to rotate in the opposite direction, so that the traction rope 6 is wrapped around the outside of the limit roller 7 again. After the inertia of the top hammer 4 ends, the limit roller 7 is in a completely stationary state, and the compression spring 18 will release its elastic potential energy, thereby pulling the card plate 16 to swing in the opposite direction and reset.Disengage from the engagement with the latching teeth 11; In the initial state, the combined cross-section of the semicircular plate 1 23 and the semicircular plate 2 24 is "circular", and the liquid inside the hydraulic cylinder 3 cannot pass through the semicircular plate 1 23 and the semicircular plate 2 24. When the metal rod 1 5 moves, the metal rod 1 5 will synchronously drive the metal rod 2 29 to move, and the internal threaded tube 38 can be rotated in different directions along the outside of the screw 37. When the internal threaded tube 38 rotates in different directions, the length of the internal threaded tube 38 on the outside of the screw 37 can be adjusted, and then the traction rope 2 30 can be adjusted to a suitable tightness. When the metal rod 29 moves, the traction rope 2 30 can be driven to move through the screw 37 and the internal threaded tube 38. Normally, the top hammer 4 When high-pressure pyrophyllite or other sealing media is used, the traction rope 2 30 will not be in a completely straight state. When the top hammer 4 is suddenly displaced, it means that the pyrophyllite or other sealing media is broken. The moving distance of the metal rod 1 5 continues to increase at this time, and the traction rope 2 30 is in a taut state. The traction rope 2 30 will pull the metal rod 31. When the metal rod 31 moves, it will pull the side arc plate 32 to move, and the movement of the side arc plate 32 will drive the baffle 33 to move. In the initial state, the baffle 33 blocks the moving direction of the semicircular plate 24. When the baffle 33 moves, the movement of the semicircular plate 24 by the baffle 33 ends, and the semicircular plate 2 4 can move, and the liquid inside the pressure relief pipe 22 will apply pressure to the semicircular plate 24. Under the pressure of the liquid, the semicircular plate 24 will drive the limiting rod 1 25 to move along the inside of the transverse plate 27, and the fit with the semicircular plate 1 23 will end. The liquid can pass through the semicircular plate 24, thereby releasing the liquid pressure inside the hydraulic cylinder 3, and when the semicircular plate 24 drives the limiting rod 1 25 to move, the limiting rod 1 25 also drives the transverse plate 1 26 to move. At this time, the transverse plate 1 26 cooperates with the transverse plate 27 to apply tension to the tension spring 28, causing the tension spring 28 to deform and generate elastic potential energy. The side arc plate 32 can also move. It will cooperate with the accommodating box 35 to squeeze the compression spring 2 36, causing the compression spring 2 36 to deform and generate elastic potential energy. When the hydraulic cylinder 3 stops running and drives the top hammer 4 to reset, the tension spring 28 will release the elastic potential energy, pulling the horizontal plate 1 26 to move in the opposite direction and reset. The horizontal plate 1 26 then drives the semicircular plate 2 24 to reset through the limit rod 1 25, so that the semicircular plate 2 24 and the semicircular plate 1 23 are fitted together again. At this time, the metal rod 31 ends pulling the side arc plate 32, and the compression spring 2 36 will release the elastic potential energy, pushing the baffle 33 to reset through the side arc plate 32, so that the baffle 33 blocks the moving route of the semicircular plate 2 24 again.
