Description

Technical Field

[0001] The invention relates to the technical field of slope protection, in particular to a water conservancy project slope protection device. Background Art

[0002] In water conservancy projects, rivers are often located between mountains. In order to ensure that the river is not blocked by falling rocks from the mountain slopes, it is necessary to prevent the falling rocks from rolling into the river. In real life, falling rocks are often blocked with the help of blocking devices, so as to prevent them from rolling into the river as much as possible.

[0003] Prior art includes an invention with publication number CN112030874B, which discloses a slope protection device for a water conservancy project, comprising a mountaintop insert located at the top of a mountain and a foothill insert located at the bottom of the mountain, a block being sleeved on the foothill insert, a taut pull rope being connected between the mountaintop insert and the foothill insert, a protection zone being formed between the mountain slope, the ground, the block and the pull rope, a buffer mechanism being provided in the protection zone of the block, and a deceleration mechanism being provided in the protection zone of the pull rope; the buffer mechanism comprising a vertical plate located in the protection zone, an elastic component being provided between the vertical plate and the block, the deceleration mechanism comprising a plurality of fixed blocks arranged at equal intervals on the pull rope, an elastic component being provided on the fixed block and perpendicular to the ground, the elastic component comprising a plurality of tubular members located on the block, a spring being provided in the tubular member extending to the protection zone and connected to the vertical plate; the problem of being unable to quickly protect the mountains on both sides of the river channel to prevent falling stones from blocking the river channel can be solved.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: elastic parts of different sizes need to be installed at different positions on the mountain slope, and the elastic parts will be damaged due to the impact of falling rocks after a period of use. Therefore, the elastic parts need to be replaced regularly. However, since the specifications of elastic parts at different positions are different, a large number of elastic parts of different specifications need to be prepared during the maintenance process, thereby increasing the subsequent maintenance costs.

[0005] To this end, we propose a slope protection device for water conservancy projects. Summary of the Invention

[0006] The purpose of the present invention is to provide a water conservancy project slope protection device to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a water conservancy project slope protection device, comprising an upper insert, a lower insert and a pull rope, wherein the two ends of the pull rope are fixedly connected to the upper insert and the lower insert respectively, and further comprising an elastic structure respectively provided on the arc surface of the pull rope for buffering and decelerating falling rocks and capable of adjusting the distance between the pull rope and the mountain slope, wherein the elastic structure comprises a suspension plate slidingly sleeved on the arc surface of the pull rope, a rubber sleeve for buffering falling rocks, a square plate for adjusting the direction of the rubber block, a sliding sleeve for limiting the position of the square plate, and a spring for adjusting the distance between the pull rope and the mountain slope according to the actual situation. The invention relates to a rubber strip which can be adaptively adjusted according to actual installation conditions; a limiting structure which is respectively arranged on the lower surface of the suspension plate and is used to limit the position of the suspension plate, and the limiting structure includes two mounting plates fixedly installed on the lower surface of the suspension plate, two clamping plates for clamping the pull rope, and a number of spikes for increasing the friction between the clamping plates and the pull rope; a protective structure which is respectively arranged on both sides of the sliding sleeve and is used to protect some parts of the elastic structure and the limiting structure, and the protective structure includes two support plates which are respectively fixedly connected to both sides of the sliding sleeve and a protective plate for shielding falling rocks.

[0008] The effects achieved by the above components are: by setting up an elastic structure, the length of the elastic structure can be adjusted during the maintenance process, thereby facilitating the replacement of the elastic structure, and there is no need for staff to carry elastic structures of different specifications, thereby reducing the cost of later maintenance. By setting up a limiting structure, the suspension plate can be adjusted to any position of the pull rope according to actual conditions, and the suspension plate can also be limited to the arc surface of the pull rope, thereby further facilitating the operation of the staff. By setting up a protective structure, the falling rocks can be blocked with the help of the protective plate, and the falling rocks can be prevented from damaging some components in the elastic structure and the limiting structure as much as possible, thereby extending the service life of the elastic structure and the limiting structure.

[0009] Preferably, the lower surface of the hanging plate is fixedly connected to a U-shaped plate, and the surfaces of the two side arms of the U-shaped plate are rotatably connected to a rotating plate, the lower surface of the rotating plate is rotatably connected to the square plate, the lower surface of the square plate is fixedly connected to a rubber block, the lower surface of the rubber block is fixedly connected to a steel pipe, the rubber sleeve is fixedly sleeved on the arc surface of the steel pipe, the rubber sleeve is fixedly connected to the rubber block, the inner wall of the steel pipe is fixedly connected to a fixing plate, a screw rod is inserted into the inner thread of the fixing plate, the lower end of the screw rod is fixedly connected to a connecting block, the connecting block is fixedly connected to the rubber strip, the size of the rubber strip is adapted to the size of the steel pipe, the surfaces of the two side arms of the U-shaped plate are threaded with screws, and both sides of the rotating plate are fixedly connected to the arc plate.

[0010] The effect achieved by the above components is: after hanging the suspension plate on the arc surface of the pull rope, the rubber strip will remain in a vertical state due to its own gravity, and then the screw will be rotated, and the screw will be pressed against the surface of the arc plate with the help of the thread movement. The screw reaches the function of limiting the position of the arc plate and then limiting the position of the rotating plate. After that, the rubber strip is rotated, and the connecting block will drive the screw to rotate with the help of the rubber strip. At this time, the screw will move in the vertical direction along the fixed plate, thereby adjusting the distance between the rubber strip and the mountain slope. Therefore, when the elastic structure is replaced later, the length of the rubber strip sliding out of the steel pipe can be adjusted according to the actual situation of the mountain slope, thereby making maintenance work simpler. When falling rocks roll down, the rubber strip and the rubber sleeve can slow down the rolling speed of the falling rocks. The rubber block can achieve the effect of causing the steel pipe to produce a certain deformation after being impacted, so that the steel pipe can be tilted at a certain angle, thereby facilitating the passage of falling rocks.

[0011] Preferably, the sliding sleeve is slidably mounted on the surface of the rotating plate, and the size of the sliding sleeve is adapted to the size of the square plate.

[0012] The effect achieved by the above components is: the sliding sleeve, when the sliding sleeve is sleeved on the surface of the square plate, reaches the position of the restricted square plate, so that the undamaged rubber sleeve on the arc surface of the steel pipe can buffer the falling rocks, so that the rubber sleeve can be fully utilized.

[0013] Preferably, the arc surface of the screw rod is fixedly connected to two blocks, and the fixing plate is located between the blocks and the connecting block.

[0014] The effect achieved by the above components is that the movement of the screw rod drives the stopper to move, and the stopper prevents the screw rod from being out of contact with the fixed plate as much as possible.

[0015] Preferably, a drive rod is connected to the mounting plate for horizontal rotation, and the arc surfaces at both ends of the drive rod are provided with threads in opposite directions. The arc surfaces of the drive rod are threadedly connected to two brackets, and the two brackets are fixedly connected to two splints respectively, and the spikes are fixedly connected to the surface of the splint.

[0016] The effect achieved by the above components is: when the driving rod rotates, the two brackets will move towards each other with the help of the thread, and the movement of the bracket will drive the splint to move. When the splint contacts the pull rope, the splint will cause the spikes to embed into the pull rope. At this time, the splint and the spikes can prevent the suspension plate from sliding along the arc surface of the pull rope as much as possible.

[0017] Preferably, the arc surface sliding sleeve of the driving rod is provided with a circular ring, and the side of the circular ring away from the mounting plate is fixedly connected to two strip plates, and the surfaces of the two strip plates are fixedly connected to grip plates, and the arc surface of the driving rod is fixedly connected to two clamping blocks, and the side of the circular ring close to the clamping block is provided with two clamping grooves, and the size of the clamping grooves is adapted to the size of the clamping block.

[0018] The effect achieved by the above components is: pulling the grip plate in the direction away from the mounting plate, the movement of the grip plate will cause the ring to slide along the arc surface of the driving rod, and when the inner wall of the slot engages with the card block, the grip plate is rotated, and the rotation of the grip plate will cause the driving rod to rotate synchronously, so that the grip plate facilitates the rotation of the driving rod, and after the slot is out of contact with the card block, it can prevent someone from accidentally touching the grip plate and causing the driving rod to rotate, resulting in loosening between the splint and the pull rope.

[0019] Preferably, a magnetic block is fixedly connected to one side of the grip plate close to the driving rod, and the driving rod is made of iron.

[0020] The effect achieved by the above components is that the sliding of the grip plate will cause the magnet to contact the drive rod. Since the drive rod is made of iron, the magnet will be attracted to the surface of the drive rod by its own magnetic force. The magnet limits the grip plate position and prevents the card block from contacting the card slot as much as possible.

[0021] Preferably, two balls are rotatably connected in the bracket, and the balls are slidably connected to the mounting plate.

[0022] The effect achieved by the above components is that the bracket drives the ball bearings to slide along the surface of the mounting plate, and the ball bearings reduce the friction between the bracket and the mounting plate, and can also limit the sliding path of the bracket to prevent the bracket from rotating as much as possible.

[0023] Preferably, the surface of the support plate is slidably connected to a sliding frame, one end of the two sliding frames is fixedly connected to the protective plate, a clearance groove is opened on the upper surface of the protective plate, the size of the clearance groove is adapted to the size of the pull rope, and a spring is fixedly connected to the side of the support plate away from the protective plate, and the other end of the spring is fixedly connected to the sliding frame.

[0024] The effect achieved by the above components is: when falling rocks hit the protective plate, the protective plate will slide toward the sliding sleeve. The sliding of the protective plate will drive the sliding frame to slide along the surface of the support plate. The sliding of the sliding frame will stretch the spring. At this time, the spring is in a stretched state. The spring can cushion the sliding frame, thereby reducing the damage caused by falling rocks to the protective plate.

[0025] Preferably, a buffer block is fixedly connected to one side of the support plate close to the protective plate, a pressure block is fixedly connected to the inner wall of the sliding frame, the pressure block is located between the buffer block and the protective plate, and the buffer block is made of silicone.

[0026] The effect achieved by the above components is: the sliding of the sliding frame will cause the pressure block to squeeze the buffer block. At this time, the buffer block made of silicone material will be compressed and deformed. The buffer block will cushion the pressure block, and further cushion the protective plate.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The present invention provides an elastic structure so that the length of the elastic structure can be adjusted during maintenance, thereby facilitating replacement of the elastic structure and eliminating the need for staff to carry elastic structures of different specifications, thereby reducing subsequent maintenance costs.

[0029] 2. The present invention sets a limiting structure, so that the hanging plate can be adjusted to any position of the pull rope according to actual conditions, and can also limit the hanging plate to the arc surface of the pull rope, thereby further facilitating the operation of the staff.

[0030] 3. The present invention sets a protective structure to block the falling rocks with the help of the protective plate, and try to prevent the falling rocks from damaging some parts of the elastic structure and the limiting structure, thereby extending the service life of the elastic structure and the limiting structure.

[0043] See also Figure 1-10The present invention provides a technical solution: a water conservancy project slope protection device, comprising an upper insert 1, a lower insert 2 and a pull rope 3, the two ends of the pull rope 3 are fixedly connected to the upper insert 1 and the lower insert 2 respectively, and also include arc surfaces respectively arranged on the pull rope 3, for buffering and decelerating falling rocks, and can also adjust the distance between the elastic structure 4 and the mountain slope, the elastic structure 4 includes a hanging plate 401 slidingly sleeved on the arc surface of the pull rope 3, a rubber sleeve 406 for buffering falling rocks, a square plate 411 for adjusting the direction of the rubber block 404, a sliding sleeve 412 for limiting the position of the square plate 411, and a rubber strip 410 for adaptive adjustment according to actual installation conditions; by setting the elastic structure 4, the length of the elastic structure 4 can be adjusted during the maintenance process, thereby facilitating the replacement of the elastic structure 4, and there is no need for staff to carry elastic structures 4 of different specifications, thereby reducing the cost of later maintenance. The limiting structures 5 are respectively arranged on the lower surface of the hanging plate 401 and are used to limit the position of the hanging plate 401. The limiting structure 5 includes two mounting plates 501 fixedly installed on the lower surface of the hanging plate 401, two clamping plates 504 for clamping the pull rope 3, and a number of spikes 505 for increasing the friction between the clamping plates 504 and the pull rope 3. By setting the limiting structure 5, the hanging plate 401 can be adjusted to any position of the pull rope 3 according to actual conditions, and the hanging plate 401 can also be limited to the arc surface of the pull rope 3, thereby further facilitating the operation of the staff. The protective structures 6 are respectively arranged on both sides of the sliding sleeve 412 to protect some parts of the elastic structure 4 and the limiting structure 5. The protective structure 6 includes two support plates 61 respectively fixedly connected to the two sides of the sliding sleeve 412 and a protective plate 63 for shielding falling rocks. By setting up the protective structure 6, the falling rocks can be blocked with the help of the protective plate 63, and the falling rocks are prevented from damaging some parts of the elastic structure 4 and the limiting structure 5 as much as possible, thereby extending the service life of the elastic structure 4 and the limiting structure 5.

[0044] The specific configuration and functions of the elastic structure 4, the limiting structure 5 and the protective structure 6 will be described in detail below.

[0045] Reference Figure 2-6As shown, in this embodiment: the lower surface of the suspension plate 401 is fixedly connected to the U-shaped plate 402, the surfaces of the arms on both sides of the U-shaped plate 402 are rotatably connected to the rotating plate 403, the lower surface of the rotating plate 403 is rotatably connected to the square plate 411, the lower surface of the square plate 411 is fixedly connected to the rubber block 404, the lower surface of the rubber block 404 is fixedly connected to the steel pipe 405, the rubber sleeve 406 is fixedly sleeved on the arc surface of the steel pipe 405, the rubber sleeve 406 is fixedly connected to the rubber block 404, and the inner wall of the steel pipe 405 A fixed plate 407 is fixedly connected, a screw rod 408 is inserted into the inner thread of the fixed plate 407, and a connecting block 409 is fixedly connected to the lower end of the screw rod 408. The connecting block 409 is fixedly connected to the rubber strip 410. The size of the rubber strip 410 is adapted to the size of the steel pipe 405. The surfaces of the arms on both sides of the U-shaped plate 402 are threaded with screw rods 413. Both sides of the rotating plate 403 are fixedly connected with an arc plate 414. After the hanging plate 401 is hung on the arc surface of the pull rope 3, the rubber strip 410 is subjected to its own weight. The force influence will keep it in a vertical state, and then the screw rod 413 will be rotated. The screw rod 413 will move with the help of the thread and press against the surface of the curved plate 414. The screw rod 413 reaches the effect of limiting the position of the curved plate 414 and thus limiting the position of the rotating plate 403. Then the rubber strip 410 will be rotated, and the connecting block 409 will drive the screw rod 408 to rotate with the help of the rubber strip 410. At this time, the screw rod 408 will move in the vertical direction along the fixed plate 407, thereby adjusting the distance between the rubber strip 410 and the mountain slope. Therefore, when the elastic structure 4 is replaced later, the length of the rubber strip 410 sliding out of the steel pipe 405 can be adjusted according to the actual situation of the mountain slope, thereby making maintenance work simpler. When falling rocks roll down, the rubber strip 410 and the rubber sleeve 406 can slow down the rolling speed of the falling rocks. The rubber block 404 reaches the effect that when the steel pipe 405 is impacted, the rubber block 404 itself can produce a certain deformation, so that the steel pipe 405 can tilt at a certain angle, thereby facilitating the passage of falling rocks.

[0046] Reference Figure 2-6 As shown, specifically, the sliding sleeve 412 slides onto the surface of the rotating plate 403. The size of the sliding sleeve 412 matches the size of the square plate 411. When the sliding sleeve 412 is inserted into the surface of the square plate 411, the sliding sleeve 412 reaches a position that restricts the square plate 411, thereby allowing the undamaged rubber sleeve 406 on the arc surface of the steel pipe 405 to cushion falling rocks, thereby allowing the rubber sleeve 406 to be fully utilized. The arc surface of the screw rod 408 is fixedly connected to two blocks 415. The fixed plate 407 is located between the blocks 415 and the connecting block 409. The movement of the screw rod 408 will drive the movement of the blocks 415. The blocks 415 can prevent the screw rod 408 from losing contact with the fixed plate 407 as much as possible.

[0047] Reference Figure 7 and Figure 8 as well as Figure 9As shown, specifically, a driving rod 502 is horizontally rotatably connected in the mounting plate 501, and the arc surface of the driving rod 502 is provided with threads in opposite directions. The arc surface of the driving rod 502 is threadedly connected to two brackets 503, and the two brackets 503 are respectively fixedly connected to the two splints 504, and the spikes 505 are fixedly connected to the surface of the splint 504. When the driving rod 502 rotates, the two brackets 503 will move towards each other with the help of the threads, and the movement of the brackets 503 will drive the splint 504 to move. When the splint 504 contacts the pull rope 3, the splint 504 will cause the spikes 505 to be embedded in the pull rope 3. At this time, the splint 504 and the spikes 505 can prevent the suspension plate 401 from sliding along the arc surface of the pull rope 3 as much as possible. The arc surface sliding sleeve of the driving rod 502 is provided with a ring 506. The side of the ring 506 away from the mounting plate 501 is fixedly connected to two strip plates 507. The surfaces of the two strip plates 507 are fixedly connected to a grip plate 508. The arc surface of the driving rod 502 is fixedly connected to two clamping blocks 509. The side of the ring 506 close to the clamping block 509 is provided with two clamping grooves 510. The size of the clamping grooves 510 is adapted to the size of the clamping block 509. The grip plate 508 is pulled in the direction away from the mounting plate 501. The movement of the grip plate 508 will cause the ring 506 to slide along the arc surface of the driving rod 502. When the inner wall of the slot 510 engages with the block 509, the grip plate 508 is rotated. The rotation of the grip plate 508 will cause the driving rod 502 to rotate synchronously. The grip plate 508 facilitates the rotation of the driving rod 502. After the slot 510 is out of contact with the block 509, it can prevent someone from accidentally touching the grip plate 508 and causing the driving rod 502 to rotate, resulting in loosening between the splint 504 and the pull rope 3.

[0048] Reference Figure 7 and Figure 8 as well as Figure 9 As shown, specifically, a magnet 511 is fixedly connected to the side of the grip plate 508 near the drive rod 502. The drive rod 502 is made of iron. When the grip plate 508 slides, the magnet 511 contacts the drive rod 502. Since the drive rod 502 is made of iron, the magnet 511 is attracted to the surface of the drive rod 502 by its own magnetic force. The magnet 511 restricts the position of the grip plate 508 and minimizes contact between the block 509 and the slot 510. Two balls 512 are rotatably connected to the bracket 503. The balls 512 are slidably connected to the mounting plate 501. The bracket 503 drives the balls 512 to slide along the surface of the mounting plate 501. The balls 512 reduce friction between the bracket 503 and the mounting plate 501 and also limit the sliding path of the bracket 503, minimizing its rotation.

[0049] Reference Figure 2 and Figure 10As shown, specifically, the surface of the support plate 61 is slidably connected to a sliding frame 62, one end of the two sliding frames 62 is fixedly connected to the protective plate 63, and a clearance groove 64 is provided on the upper surface of the protective plate 63. The size of the clearance groove 64 is adapted to the size of the pull rope 3. The side of the support plate 61 away from the protective plate 63 is fixedly connected to a spring 65, and the other end of the spring 65 is fixedly connected to the sliding frame 62. When a falling rock hits the protective plate 63, the protective plate 63 will slide toward the direction close to the sliding sleeve 412. The sliding of the protective plate 63 will drive the sliding frame 62 to slide along the surface of the support plate 61. The sliding of the sliding frame 62 will stretch the spring 65. At this time, the spring 65 is in a stretched state. The spring 65 can buffer the sliding frame 62, thereby reducing the damage caused by the falling rock to the protective plate 63. A buffer block 66 is fixedly connected to one side of the support plate 61 close to the protective plate 63, and a pressure block 67 is fixedly connected to the inner wall of the sliding frame 62. The pressure block 67 is located between the buffer block 66 and the protective plate 63. The buffer block 66 is made of silicone. The sliding of the sliding frame 62 will cause the pressure block 67 to squeeze the buffer block 66. At this time, the buffer block 66 made of silicone will be compressed and deformed, and the buffer block 66 will buffer the pressure block 67, thereby further buffering the protective plate 63.

[0050] Working principle: When it is necessary to use the elastic structure 4 to buffer the falling rocks, the upper insert 1 and the lower insert 2 are both installed in the mountain, and then the suspension plate 401 is hung on the arc surface of the pull rope 3. At this time, the rubber strip 410 will remain in a vertical state due to its own gravity, and then the screw 413 is rotated. The screw 413 will move with the help of the thread and press against the surface of the arc plate 414. The screw 413 reaches the position of the arc plate 414 and then limits the position of the rotating plate 403. Then, the rubber strip 410 is rotated, and the connecting block 409 rotates with the help of the rubber strip 410 to drive the screw rod 408 to rotate. At this time, the screw rod 408 will move in the vertical direction along the fixed plate 407, thereby adjusting the distance between the rubber strip 410 and the mountain slope. Therefore, when the elastic structure 4 is replaced later, the length of the rubber strip 410 sliding out of the steel pipe 405 can be adjusted according to the actual situation of the mountain slope, thereby making maintenance work simpler, and the movement of the screw rod 408 will also When the steel pipe 405 is hit, the rubber block 404 can deform to a certain extent, so that the steel pipe 405 can tilt to a certain angle, thereby facilitating the passage of the falling rock. When one side of the rubber strip 410 and the rubber sleeve 406 is damaged, the sliding sleeve 412 slides upward along the surface of the rotating plate 403. When the sliding sleeve 412 is out of contact with the square plate 411, the square plate 411 is rotated 180 degrees, and then the sliding sleeve 412 slides downward. When the sliding sleeve 412 is again sleeved on the surface of the square plate 411, the sliding sleeve 412 reaches the position of restricting the square plate 411, thereby allowing the undamaged rubber sleeve 406 on the arc surface of the steel pipe 405 to continue to cushion the falling rock, thereby allowing the rubber sleeve 406 to be fully utilized.

[0051] When the limiting structure 5 needs to be used, the grip plate 508 is pulled in the direction away from the mounting plate 501. The movement of the grip plate 508 will cause the ring 506 to slide along the arc surface of the driving rod 502. When the inner wall of the slot 510 is engaged with the block 509, the grip plate 508 is rotated. The rotation of the grip plate 508 will cause the driving rod 502 to rotate synchronously. When the driving rod 502 rotates, the two brackets 503 will move towards each other with the help of the thread. The bracket 503 will drive the ball 512 to slide along the surface of the mounting plate 501. The ball 512 can reduce the friction between the bracket 503 and the mounting plate 501, and can also limit the sliding path of the bracket 503, and try to prevent the bracket 503 from rotating. The movement of the bracket 503 will drive the splint 504 to move. When the splint 504 contacts the pull rope 3, The clamping plate 504 will make the spike 505 embedded in the pull rope 3. At this time, the clamping plate 504 and the spike 505 can prevent the suspension plate 401 from sliding along the arc surface of the pull rope 3 as much as possible. Then the grip plate 508 is slid in the direction close to the driving rod 502. The sliding of the grip plate 508 will cause the card slot 510 to be out of contact with the card block 509. At this time, it can prevent someone from accidentally touching the grip plate 508 and causing the driving rod 502 to rotate, resulting in loosening between the clamping plate 504 and the pull rope 3. The sliding of the grip plate 508 will cause the magnet 511 to contact the driving rod 502. Since the driving rod 502 is made of iron, the magnet 511 will be attracted to the surface of the driving rod 502 by its own magnetic force. The magnet 511 reaches the position of the clamping plate 508, preventing the card block 509 from contacting the card slot 510 as much as possible.

[0052] When a falling rock hits the protective plate 63, the protective plate 63 will slide in the direction close to the sliding sleeve 412. The sliding of the protective plate 63 will drive the sliding frame 62 to slide along the surface of the support plate 61. The sliding of the sliding frame 62 will stretch the spring 65. At this time, the spring 65 is in a stretched state. The spring 65 can buffer the sliding frame 62, thereby reducing the damage caused by the falling rock to the protective plate 63. The sliding of the sliding frame 62 continues to cause the pressure block 67 to squeeze the buffer block 66. At this time, the buffer block 66 made of silicone will be compressed and deformed. The buffer block 66 will buffer the pressure block 67, and then further buffer the protective plate 63. The yield groove 64 can prevent the pull rope 3 from interfering with the sliding of the protective plate 63 as much as possible, and the protective plate 63 can prevent the falling rock from hitting some parts between the elastic structure 4 and the limit, thereby extending the service life of other parts.
