Description

Technical Field

[0001] This invention relates to the field of fire protection technology, and more specifically, to a fire protection engineering pipeline construction device. Background Technology

[0002] Fire protection engineering refers to a series of projects and measures aimed at fire prevention, control, and extinguishing, in order to protect people's lives and property to the greatest extent possible and reduce fire risks; fire pipelines refer to pipeline materials used in fire protection to connect fire protection equipment and materials and to transport fire-fighting water, gas, or other media.

[0003] Fire protection pipelines are typically laid and installed either overhead or underground. For ease of installation and quick transportation, during underground pipe laying, hoisting machinery is used to place the fire protection pipelines into the pit, and they are then installed on-site by splicing sections together. Since fire protection pipelines are mostly made of steel and are quite heavy, hoisting equipment is used to transfer the pipelines to the pit during the laying process. During hoisting and installation, the pipelines will sway due to inertia, causing the center axis of the already placed pipelines to be misaligned with the center axis of the hoisted pipelines. Therefore, workers need to manually straighten the pipelines to reduce the error between adjacent pipelines.

[0004] Chinese patent application CN114955857B discloses a pipe laying device for fire protection engineering. During the movement of the linkage rod, the inner support block moves outward to provide internal support for the fire protection pipe, thereby increasing the stability of the fire protection pipe during the hoisting process.

[0005] The aforementioned patent still has the following shortcomings: However, as the weight of the pipeline increases, its inertia is also relatively large. Therefore, workers need to apply a lot of force to straighten the pipeline, which increases the workload of the workers. At the same time, it is difficult to control the amplitude of pipeline swaying, which can easily cause the fire-fighting pipeline to collide with the side wall of the tunnel. Especially when the side wall of the tunnel is embedded with solid construction waste such as stones, if a collision occurs, it can easily cause the fire-fighting pipeline to deform and be damaged. Therefore, when high-pressure water flows in the pipeline, it can easily cause the pipeline to rupture, which poses a certain danger.

[0006] Therefore, a fire protection engineering pipeline construction device is proposed. Summary of the Invention

[0007] In view of the problems existing in the prior art, the purpose of this invention is to provide a fire protection engineering pipeline construction device that can improve the stability of the pipeline during the process of the pipeline entering the tunnel and reduce the probability of the pipeline colliding with the side wall of the tunnel.

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A fire protection engineering pipeline construction device includes a base, which is installed vertically on the ground during installation.

[0010] The base is symmetrically equipped with guide rails, and a crossbar is slidably mounted on the two guide rails. A hydraulic rod is provided between the crossbar and the guide rail, and the hydraulic rod is used to drive the crossbar to move along the guide rail.

[0011] It also includes an installation sleeve, with a lifting mechanism on the crossbar for moving the installation sleeve up and down. Two clamping plates are symmetrically and movably installed on the outer wall of the installation sleeve. The clamping plates are arc-shaped. The installation sleeve is equipped with a first driving mechanism that cooperates with the clamping plates. The first driving mechanism drives the two clamping plates to move closer to each other, thereby clamping the pipe.

[0012] A sleeve is hinged to the side wall of the clamping plate, and the sleeve can rotate around the hinge point. A limiting block that cooperates with the sleeve is fixedly installed on the side wall of the clamping plate. The sleeve is filled with buffer solution, which is shock-absorbing oil. A piston is slidably installed inside the sleeve. The piston has a through hole, so the piston can move inside the sleeve. An insert rod that penetrates the sleeve is fixedly installed on the side wall of the piston. When the insert rod encounters resistance, it drives the piston to move in the sleeve. At the same time, the buffer solution and the side wall of the through hole rub against each other, and the kinetic energy of the insert rod is converted into the internal energy of the piston and the buffer solution, reducing the kinetic energy of the insert rod and the pipeline, and reducing the swing amplitude of the pipeline. A pressure reducing plate is installed at the end of the insert rod, which can reduce the pressure of the insert rod on the side wall of the tunnel and prevent the insert rod from inserting into the soil of the side wall of the tunnel, thus ensuring that the insert rod can be fixed on the surface of the tunnel. The limiting block can prevent the insert rod from being in a vertical state, thus ensuring that the pressure reducing plate can contact the side wall of the tunnel.

[0013] An elastic protective sleeve is fixedly installed on the outer wall of the sleeve. The elastic protective sleeve is used to protect the insertion rod. The elastic protective sleeve is an elastic bellows. The elastic bellows is sleeved on the outside of the sleeve and the insertion rod, which can isolate the connection between the insertion rod and the sleeve from the outside world, thereby preventing particulate matter from adhering to the surface of the insertion rod. During the extension and retraction of the insertion rod, it plays a role in reducing the wear between the insertion rod and the sleeve. Since the elastic bellows is made of elastic material, it will be in a naturally extended state when the elastic bellows is not subjected to external pressure. Therefore, under the action of the elastic bellows, the insertion rod can be in a state of extending out of the sleeve when the pressure reducing plate is not in contact with the tunnel side wall.

[0014] The side wall of the clamp is provided with an installation groove, in which an elastic airbag is fixedly installed. The installation sleeve is equipped with an air pump whose output end is connected to the elastic airbag, and the air pump supplies air to two elastic airbags on the same installation sleeve at the same time. The sleeve is equipped with a triggering mechanism that cooperates with the air pump. When the piston is about to hit the sleeve, the triggering mechanism controls the air pump to work. At this time, the elastic airbag expands rapidly. The expanded elastic airbag will contact the side wall and bottom wall of the tunnel. At this time, the expanded elastic airbag can lift the clamp and the pipe, thereby increasing the resistance of the pipe and the clamp in the horizontal direction, thus reducing the swing amplitude and speed of the pipe in the horizontal direction, and improving the protection effect of the pipe.

[0015] The clamp plate has a cavity, and the side wall of the cavity near the sleeve has evenly spaced holes. A pressure relief valve is embedded in the output end of the elastic airbag, and the output end of the pressure relief valve is connected to the cavity. Therefore, when the elastic airbag is fully expanded, it releases gas into the cavity through the pressure relief valve. At this time, the gas in the cavity is evenly discharged through the holes and impacts the side wall of the tunnel. The clamp plate is subjected to a reaction force, which reduces the swing amplitude and speed of the clamp plate and the pipeline, and improves the protection effect on the pipeline and the clamp plate.

[0016] Furthermore, the triggering mechanism includes a groove formed on the inner wall of the sleeve, an elastic pad installed in the groove, and a switch fixedly installed on the elastic pad. Therefore, when the piston moves to the switch surface, it can squeeze the switch and retract the switch into the groove. The switch is electrically connected to the air pump and is used to control the start and stop of the air pump. Therefore, by adjusting the position of the switch, the switch can be squeezed before the piston hits the side wall of the sleeve, thereby triggering the air pump to work.

[0017] Furthermore, the lifting mechanism includes two rotating rods rotatably inserted into the crossbar. A receiving wheel and a gear are fixedly sleeved on each rotating rod. The two gears mesh, allowing them to rotate synchronously. A motor and a magnetic coupling are mounted on the crossbar, driving the magnetic coupling via the motor. One of the rotating rods is installed at the output end of the magnetic coupling, enabling the motor to rotate the rotating rod. Both ends of the crossbar are equipped with pulleys, and steel wire ropes are fixedly installed between the mounting sleeves and the receiving wheels, passing above the corresponding pulleys. Therefore, during the rotation of one rotating rod by the motor, under the action of the gears, both steel wire ropes are simultaneously wound onto the receiving wheel, or simultaneously unwound from the receiving wheel, thus driving the two mounting sleeves to move up and down synchronously, improving the stability during the pipeline transfer process.

[0018] Furthermore, the first driving mechanism includes a bidirectional threaded rod rotatably mounted on the bottom wall of the mounting sleeve. A clamping plate is threaded onto the bidirectional threaded rod, and during the rotation of the bidirectional threaded rod, the movement of the clamping plate is restricted by a guide rod that passes through the clamping plate. At this time, the two clamping plates on the same bidirectional threaded rod move closer or further apart simultaneously. When it is necessary to use the clamping plate to fix the pipeline, the bidirectional threaded rod is rotated, and the two clamping plates on the bidirectional threaded rod move closer together, gradually clamping the pipeline. After the pipeline moves into the tunnel, the bidirectional threaded rod is rotated in the opposite direction, and the two clamping plates move further apart and gradually disengage from the pipeline.

[0019] Furthermore, a movable magnet is fixedly installed on the insertion rod, and a fixed magnet that attracts the movable magnet is fixedly installed on the crossbar. When the clamping plate picks up the stacked pipes, the clamping plate approaches the crossbar. At this time, under the attraction between the fixed magnet and the movable magnet, the insertion rod slowly retracts into the sleeve, and the elastic protective sleeve deforms, thus facilitating the clamping plate to pick up the pipes. When the clamping plate enters the tunnel, the clamping plate moves away from the crossbar. At this time, the attraction between the movable magnet and the fixed magnet decreases, so the elastic protective sleeve recovers and the insertion rod can move freely along the sleeve, thus enabling the insertion rod to work normally. An electromagnet that attracts the movable magnet is fixedly installed on the mounting sleeve. When the clamping plate loses contact with the pipe and needs to be removed from the tunnel, the electromagnet is energized. At this time, the movable magnet is attracted by the magnetic field around the electromagnet, so the insertion rod retracts into the sleeve, and the pressure reducing plate loses contact with the tunnel side wall, thus facilitating the upward movement of the clamping plate.

[0020] When the length of the pipe to be moved is greater than the length of the crossbar, the staff can manually push the insertion rod back into the sleeve, making it easier to clamp the pipe.

[0021] Furthermore, a friction plate is installed on the bottom wall of the elastic airbag. When the elastic airbag inflates and the fixing plate contacts the ground, the elastic airbag is fixed to the ground under the action of the friction plate. This prevents the elastic airbag from moving during the pipe swinging process, thereby improving the friction effect of the elastic airbag on the pipe. In addition, under the action of the elastic airbag's own elasticity, when the elastic airbag is not inflated, it will shake as the clamping plate moves. At this time, the impurities attached to the surface of the friction plate will fall off, thereby ensuring the roughness of the friction plate surface and ensuring that the friction plate can be fixed to the ground.

[0022] Furthermore, the friction plate has mounting holes, and an elastic rope is fixedly installed in the mounting holes. An impact block is fixedly installed on the elastic rope, and the elastic airbag is equipped with a second drive mechanism that cooperates with the impact block. Through the cooperation between the drive mechanism and the elastic rope, the impact block can be driven to swing in the mounting holes. By impacting the side wall of the mounting holes, the friction plate can be subjected to impact force, shaking off impurities on the surface of the friction plate, thus ensuring that the surface of the friction plate can maintain a rough state.

[0023] Furthermore, the second driving mechanism includes an exhaust valve embedded in the elastic airbag. The exhaust valve is a solenoid valve, which can be remotely controlled. The output end of the exhaust valve is connected to the mounting hole, and a filter screen is detachably installed in the mounting hole. The filter screen can prevent large impurities from getting stuck in the mounting hole, thus ensuring that the impact block can move normally. When the pipeline is aligned, the remotely controlled exhaust valve opens, which allows the elastic airbag to exhaust air. The airflow impacts the impact block, thereby driving the impact block to strike the mounting hole.

[0024] Furthermore, the mounting hole is funnel-shaped, and the diameter of the mounting hole near the elastic airbag end is smaller than the diameter of the end away from the elastic airbag.

[0025] Furthermore, the mounting hole is funnel-shaped, and the diameter of the mounting hole near the elastic airbag is smaller than the diameter of the end away from the elastic airbag; therefore, when the elastic airbag is not venting, the impact block can be pulled to fit against the side wall of the mounting hole by the elastic rope, thereby protecting the exhaust valve and preventing dust from directly adhering to the surface of the exhaust valve; when the elastic rope is stretched, the impact block will move to the end with the larger diameter of the mounting hole, thereby allowing the impact block to swing freely within the mounting hole.

[0026] Furthermore, the pressure-reducing plate has a movable groove, in which a ball bearing is movably embedded. The ball bearing can rotate freely within the groove and is fixedly connected to the insertion rod. Therefore, when the pressure-reducing plate contacts the tunnel sidewall and the pipe moves downward, the contact area between the pressure-reducing plate and the tunnel sidewall can be increased by the plate rotating around the ball bearing, thereby improving the support effect of the pressure-reducing plate. Moreover, the end of the elastic protective sleeve away from the sleeve is fixedly connected to the pressure-reducing plate, thus preventing external dust and other particles from entering the movable groove and ensuring that the ball bearing can rotate normally.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] (1) By setting up sleeves, limit blocks and insert rods, this solution can reduce the swaying amplitude of the pipeline as it enters the tunnel and moves down along the tunnel, thereby reducing the probability of the pipeline hitting the side wall of the tunnel, thus protecting the pipeline and making the pipeline move stably.

[0029] (2) This scheme sets up an elastic airbag, an air pump, and a triggering mechanism; when the pipeline is still in a state of large-scale swing in the tunnel, the elastic airbag in the expanded state applies an upward supporting force to the pipeline and the clamping plate, thereby increasing the resistance to the horizontal swing of the pipeline and the clamping plate, further reducing the kinetic energy of the pipeline and improving the stability.

[0030] (3) This solution, by setting up mounting holes, elastic ropes, impact blocks and exhaust valves, enables the impact blocks to impact the side wall of the mounting holes during the exhaust process of the elastic airbag, thereby transmitting the impact force to the friction plate, shaking off the impurities on the surface of the friction plate, ensuring that the friction plate remains rough, and thus ensuring that the friction plate can be fixed to the ground.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example

[0041] Please see Figures 1 to 7 A fire protection engineering pipeline construction device includes a base 1, wherein when installing the base 1, the base 1 is vertically installed on the ground;

[0042] The base 1 is symmetrically provided with guide rails 2, and a crossbar 3 is slidably installed on the two guide rails 2. A hydraulic rod 4 is provided between the crossbar 3 and the guide rail 2. The hydraulic rod 4 is used to drive the crossbar 3 to move along the guide rail 2.

[0043] It also includes an installation sleeve 5. The crossbar 3 is equipped with a lifting mechanism for moving the installation sleeve 5 up and down. Two clamping plates 6 are symmetrically and movably installed on the outer wall of the installation sleeve 5. The clamping plates 6 are arc-shaped. The installation sleeve 5 is equipped with a first driving mechanism that cooperates with the clamping plates 6. The first driving mechanism drives the two clamping plates 6 to move closer to each other, thereby clamping the pipe.

[0044] A sleeve 7 is hinged to the side wall of the clamping plate 6. The sleeve 7 can rotate around the hinge point. A limiting block 8 that mates with the sleeve 7 is fixedly installed on the side wall of the clamping plate 6. The sleeve 7 contains a buffer solution, which is a shock-absorbing oil. A piston 9 is slidably installed inside the sleeve 7. The piston 9 has a through hole, through which the buffer solution can move to the space on both sides of the piston 9 inside the sleeve 7. Therefore, the piston 9 can move inside the sleeve 7. A rod 10 that penetrates the sleeve 7 is fixedly installed on the side wall of the piston 9. When the rod 10 encounters resistance, it drives the piston 9 to move inside the sleeve 7. Meanwhile, the buffer solution rubs against the sidewall of the through hole, and the kinetic energy of the insertion rod 10 is converted into the internal energy of the piston 9 and the buffer solution, reducing the kinetic energy of the insertion rod 10 and the pipe, and reducing the swing amplitude of the pipe. The end of the insertion rod 10 is equipped with a pressure reducing plate 11, which can reduce the pressure of the insertion rod 10 on the sidewall of the tunnel and prevent the insertion rod 10 from being inserted into the soil of the sidewall of the tunnel, thus ensuring that the insertion rod 10 can be fixed on the surface of the tunnel. By setting the limiting block 8, the insertion rod 10 can be prevented from being in a vertical state, thus ensuring that the pressure reducing plate 11 can contact the sidewall of the tunnel.

[0045] An elastic protective sleeve 12 is fixedly installed on the outer wall of the sleeve 7. The elastic protective sleeve 12 is used to protect the insertion rod 10. The elastic protective sleeve 12 is an elastic bellows. The elastic bellows is sleeved on the outside of the sleeve 7 and the insertion rod 10. It can isolate the connection between the insertion rod 10 and the sleeve 7 from the outside world, thereby preventing particulate matter from adhering to the surface of the insertion rod 10. During the extension and retraction of the insertion rod 10, it plays a role in reducing the wear of the insertion rod 10 and the sleeve 7.

[0046] Since the elastic bellows is made of elastic material, it will be in a naturally extended state when it is not subjected to external pressure. Therefore, under the action of the elastic bellows, the rod 10 can be extended from the sleeve 7 when the pressure reducing plate 11 is not in contact with the tunnel side wall.

[0047] An installation groove is provided on the side wall of the clamp plate 6, and an elastic airbag 13 is fixedly installed in the installation groove. An air pump 14 with an output end connected to the elastic airbag 13 is provided on the mounting sleeve 5, and the air pump 14 supplies air to the two elastic airbags 13 on the same mounting sleeve 5 at the same time. A triggering mechanism that cooperates with the air pump 14 is provided on the sleeve 7. When the piston 9 is about to hit the sleeve 7, the triggering mechanism controls the air pump 14 to work. At this time, the elastic airbag 13 expands rapidly. The expanded elastic airbag 13 will contact the side wall and bottom wall of the tunnel. At this time, the clamp plate 6 and the pipeline can be lifted by the expanded elastic airbag 13, thereby increasing the resistance of the pipeline and clamp plate 6 in the horizontal direction, thereby reducing the swing amplitude and speed of the pipeline in the horizontal direction and improving the protection effect of the pipeline.

[0048] A cavity 15 is provided on the clamping plate 6. Holes 16 are evenly provided on the side wall of the cavity 15 near the sleeve 7. A pressure relief valve 17 is embedded on the output end of the elastic airbag 13. The output end of the pressure relief valve 17 is connected to the cavity 15. Therefore, when the elastic airbag 13 is inflated to its maximum extent, the elastic airbag 13 exhausts gas into the cavity 15 through the pressure relief valve 17. At this time, the gas in the cavity 15 is evenly discharged through the holes 16 and impacts the tunnel side wall. At this time, the clamping plate 6 is subjected to a reaction force, thereby reducing the swing amplitude and speed of the clamping plate 6 and the pipeline, and improving the protection effect on the pipeline and the clamping plate 6.

[0049] like Figure 5 As shown, the triggering mechanism includes a groove formed on the inner side wall of the sleeve 7, an elastic pad 18 installed in the groove, and a switch 19 fixedly installed on the elastic pad 18. Therefore, when the piston 9 moves to the surface of the switch 19, it can squeeze the switch 19 and cause the switch 19 to retract into the groove. The switch 19 is electrically connected to the air pump 14 and is used to control the start and stop of the air pump 14. Therefore, by adjusting the position of the switch 19, the switch 19 can be squeezed before the piston 9 hits the side wall of the sleeve 7, thereby triggering the air pump 14 to work.

[0050] like Figure 3As shown, the lifting mechanism includes two rotating rods 20 rotatably inserted on the crossbar 3. A receiving wheel 21 and a gear 22 are fixedly sleeved on each rotating rod 20. The two gears 22 mesh, allowing them to rotate synchronously. A motor and a magnetic coupling are mounted on the crossbar 3. The motor drives the magnetic coupling, and one of the rotating rods 20 is installed at the output end of the magnetic coupling, enabling the motor to rotate the rotating rod 20. Both ends of the crossbar 3 are equipped with pulleys 23. A steel wire rope 24 is fixedly installed between the mounting sleeve 5 and the receiving wheel 21, passing above the corresponding pulley 23. Therefore, during the rotation of one of the rotating rods 20 by the motor, under the action of the gear 22, both steel wire ropes 24 are simultaneously wound onto the receiving wheel 21, or simultaneously unwound from the receiving wheel 21, thus driving the two mounting sleeves 5 to move synchronously up and down, improving the stability during the pipeline transfer process.

[0051] like Figure 4 As shown, the first driving mechanism includes a bidirectional threaded rod 25 rotatably mounted on the bottom wall of the mounting sleeve 5. A clamping plate 6 is threaded onto the bidirectional threaded rod 25. During the rotation of the bidirectional threaded rod 25, the movement of the clamping plate 6 is restricted by a guide rod that passes through the clamping plate 6. At this time, the two clamping plates 6 on the same bidirectional threaded rod 25 move closer or further away simultaneously. When it is necessary to use the clamping plate 6 to fix the pipeline, the bidirectional threaded rod 25 is rotated. At this time, the two clamping plates 6 on the bidirectional threaded rod 25 move closer to each other and gradually clamp the pipeline. After the pipeline moves into the tunnel, the bidirectional threaded rod 25 is rotated in the opposite direction. At this time, the two clamping plates 6 move further away from each other and gradually disengage from the pipeline.

[0052] like Figure 4 As shown, a movable magnet 26 is fixedly installed on the insertion rod 10, and a fixed magnet 27, which attracts the movable magnet 26, is fixedly installed on the crossbar 3. When the clamping plate 6 clamps the stacked pipes, the clamping plate 6 approaches the crossbar 3. At this time, under the attraction between the fixed magnet 27 and the movable magnet 26, the insertion rod 10 slowly retracts into the sleeve 7, and the elastic protective sleeve 12 deforms, thus facilitating the clamping plate 6 to clamp the pipes. When the clamping plate 6 enters the tunnel, the clamping plate 6 moves away from the crossbar 3. At this time, the attraction between the movable magnet 26 and the fixed magnet 27 decreases, therefore... The elastic protective sleeve 12 is restored and the insertion rod 10 can move freely along the sleeve 7, which enables the insertion rod 10 to work normally. An electromagnet 28 that attracts the moving magnet 26 is fixedly installed on the mounting sleeve 5. When the clamp 6 is out of contact with the pipe and needs to be removed from the tunnel, the electromagnet 28 is energized. At this time, the moving magnet 26 is attracted by the magnetic field around the electromagnet 28, so the insertion rod 10 retracts into the sleeve 7 and the pressure reducing plate 11 is out of contact with the tunnel side wall, which facilitates the upward movement of the clamp 6.

[0053] When the length of the pipe to be moved is greater than the length of the crossbar 3, the staff can manually push the insertion rod 10 back into the sleeve 7, which makes it easier to clamp the pipe.

[0054] like Figure 6 As shown, a friction plate 29 is installed on the bottom wall of the elastic airbag 13. When the elastic airbag 13 inflates and the fixing plate contacts the ground, the elastic airbag 13 is fixed to the ground under the action of the friction plate 29. This prevents the elastic airbag 13 from moving during the pipe swinging process, thereby improving the friction effect of the elastic airbag 13 on the pipe. Furthermore, under the action of the elastic force of the elastic airbag 13 itself, when the elastic airbag 13 is not inflated, the elastic airbag 13 will shake as the clamping plate 6 moves. At this time, the impurities attached to the surface of the friction plate 29 will fall off, thereby ensuring the roughness of the surface of the friction plate 29 and ensuring that the friction plate 29 can be fixed to the ground.

[0055] like Figure 6 As shown, the friction plate 29 has a mounting hole, and an elastic rope 30 is fixedly installed in the mounting hole. An impact block 31 is fixedly installed on the elastic rope 30. The elastic airbag 13 is provided with a second drive mechanism that cooperates with the impact block 31. Through the cooperation between the drive mechanism and the elastic rope 30, the impact block 31 can be driven to swing in the mounting hole. By impacting the side wall of the mounting hole, the friction plate 29 can be subjected to impact force, shaking off impurities on the surface of the friction plate 29, thus ensuring that the surface of the friction plate 29 can maintain a rough state.

[0056] like Figure 6 As shown, the second driving mechanism includes an exhaust valve 32 embedded in the elastic airbag 13. The exhaust valve 32 is a solenoid valve, so it can be remotely controlled. The output end of the exhaust valve 32 is connected to the mounting hole, and a filter screen 33 is detachably installed in the mounting hole. Under the action of the filter screen 33, large impurities can be prevented from getting stuck in the mounting hole, which ensures that the impact block 31 can move normally. When the pipeline is aligned, the remotely controlled exhaust valve 32 is opened, which allows the elastic airbag 13 to exhaust air. The airflow impacts the impact block 31, thereby driving the impact block 31 to impact the mounting hole.

[0057] like Figure 6 As shown, the mounting hole is funnel-shaped, and the diameter of the mounting hole near the elastic airbag 13 is smaller than the diameter of the end away from the elastic airbag 13. Therefore, when the elastic airbag 13 is not venting, the impact block 31 can be pulled to fit against the side wall of the mounting hole by the elastic rope 30, thereby protecting the exhaust valve 32 and preventing dust from directly adhering to the surface of the exhaust valve 32. When the elastic rope 30 is stretched, the impact block 31 will move to the end with the larger diameter of the mounting hole, so that the impact block 31 can swing freely in the mounting hole.

[0058] like Figure 1 As shown, the pressure reducing plate 11 has a movable groove, in which a ball bearing 34 is movably embedded. The ball bearing 34 can rotate freely within the movable groove. The ball bearing 34 is fixedly connected to the insertion rod 10. Therefore, when the pressure reducing plate 11 contacts the tunnel side wall and the pipe moves downward, the contact area between the pressure reducing plate 11 and the tunnel side wall can be increased by rotating the pressure reducing plate 11 around the ball bearing 34, thereby improving the support effect of the pressure reducing plate 11. Furthermore, the end of the elastic protective sleeve 12 away from the sleeve 7 is fixedly connected to the pressure reducing plate 11, thus preventing external dust and other particles from entering the movable groove and ensuring that the ball bearing 34 can rotate normally.
