Description

Technical Field

[0001] This invention relates to the field of building construction equipment technology, and in particular to a construction equipment that utilizes prefabricated retaining walls to assemble an arched structure. Background Technology

[0002] In various construction projects such as municipal roads, bridges, tunnel portals, water conservancy embankments, and slope protection, arched retaining walls are widely used in roadbed support, underground passage retaining walls, river embankment reinforcement, and mountain slope protection due to their comprehensive advantages, including balanced mechanical stress, strong overall structural stability, small footprint, and outstanding resistance to deformation. Currently, arched retaining wall construction has gradually abandoned the traditional on-site cast-in-place process, fully shifting to a prefabricated component factory production and on-site assembly operation mode. Compared to cast-in-place construction, prefabrication and assembly technology offers higher standardization, more stable molding quality, and shorter on-site construction cycles. It also effectively reduces dust and wastewater emissions at the construction site, demonstrating significant green and environmentally friendly advantages, and has now become the mainstream technical route for arched retaining wall construction in the industry.

[0003] However, in actual assembly operations, the main body of precast retaining walls is mostly a large-volume rigid concrete component. It has a large self-weight, hard texture, and weak impact resistance at the edges and corners. When the components are flipped and aligned or the arch is spliced, the components and the connecting base are very likely to have hard contact and rigid collision. Such impacts often cause problems such as cracking of the edges and corners of the precast retaining wall, peeling off of the surface concrete, and damage to the surface layer. This not only damages the appearance of the components and affects the overall look of the project, but also directly damages the original structural strength and protective performance of the components.

[0004] In view of this, we have studied and improved the existing problems and provided a construction equipment that uses prefabricated retaining walls to assemble an arch structure. The aim of this technology is to solve the problems and improve its practical value. Summary of the Invention

A buffer assembly includes an arc-shaped rod fixed to one side of an arc-shaped plate, a connecting rod slidably mounted on the arc-shaped rod, a buffer plate fixed to one end of the connecting rod, a buffer cylinder fixed to the arc-shaped plate, a piston rod slidably mounted inside the buffer cylinder, one end of the piston rod being connected to the connecting rod, and an exhaust pipe communicating with the side wall of the buffer cylinder. The regulating component includes an exhaust pipe connected to one end of an exhaust pipe, the exhaust pipe having a plurality of exhaust holes on its side wall, and a plug being slidably disposed inside the exhaust pipe; A detection component is disposed on one side of the buffer plate.

[0007] Preferably, a motor is mounted on the slide, and the output end of the motor drives a roller, which rolls in cooperation with the track.

[0008] Preferably, the support base is equipped with an electric push rod that drives the placement plate to move, a second motor that drives the rotating plate to rotate is installed on one side of the circular plate, and a third motor that drives the threaded rod to rotate is installed at the bottom of the rotating plate.

[0009] Preferably, the arc-shaped plate has a sliding groove, and the connecting rod slides along the inside of the sliding groove.

[0010] Preferably, the adjusting assembly further includes a rack rod fixed to the bottom end of the crossbeam, a lead screw is rotatably connected inside the exhaust pipe, a toothed ring that meshes with the rack rod is sleeved on the outside of the lead screw, and the plug is threaded onto the outer wall of the lead screw.

[0011] Preferably, the detection component includes a sliding plate that slides within the inner cavity of the buffer plate, a contact plate fixed to one side of the sliding plate, a hollow internal structure of the buffer plate, a connecting pipe connecting the buffer plate to the exhaust pipe, a venting pipe connected to the side wall of the buffer plate, a whistle installed at the open end of the venting pipe, a pressure relief valve installed on the outer wall of the venting pipe, a pressure sensor installed within the inner cavity of the buffer plate, and the pressure sensor and the pressure relief valve connected via a signal.

[0012] Preferably, the detection assembly further includes a housing fixed to the vehicle body, a rotating rod rotatably disposed inside the housing, gear one being sleeved at both ends of the rotating rod via one-way bearings, gear two being fixedly sleeved at the center of the rotating rod, a U-shaped rod being fixed to one side of the slide block, a rack one being fixed on the U-shaped rod and intermittently meshing with gear one, and rack two being slidably disposed inside the housing and meshing with gear two, the end of rack two being connected to a circular plate.

[0013] Preferably, a first spring is sleeved on the outer wall of the arc-shaped rod, and a second spring is fixedly connected between the arc-shaped plate and the circular plate.

[0014] Preferably, the outer wall of the buffer cylinder is connected to the air intake pipe, a one-way valve is installed inside the air intake pipe, and a one-way valve is installed inside the exhaust pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, after being clamped by a prefabricated retaining wall, the motor drives the rotating plate to rotate the prefabricated retaining wall towards the arch beam. When the support seat touches the buffer plate, the connecting rod slides along the arc-shaped rod to compress the first spring, forming a primary buffer. At the same time, the piston rod compresses the gas in the buffer cylinder, achieving a secondary buffer through gas resistance. This dual structure avoids rigid collisions between components and prevents damage from impacts. When the slide moves to the leftmost end, the rack and pinion mesh with the gear ring, which can adaptively adjust the buffering force according to the curvature of the prefabricated retaining wall. When the curvature increases, the impact speed of the component increases, and the rack and pinion drive the lead screw to push the plug to block more vent holes, slowing down the venting and increasing the damping to strengthen the buffering. When the curvature decreases, the impact speed slows down, and the plug moves in the opposite direction, reducing the blocking of vent holes, accelerating the venting, and reducing the damping. Thus, the buffering strength can be adaptively adjusted according to the change in the curvature of the prefabricated retaining wall, keeping the buffering effect within a reasonable range and further ensuring the stability of the assembly operation.

[0016] 2. This invention uses a starting motor to drive a guide wheel along a track, causing the hydraulic gripper to move above the precast retaining wall. The hydraulic cylinder then drives the gripper downwards to clamp the component, lifting the material. Subsequently, the starting motor reverses direction, transferring the precast retaining wall to the installation position. Compared to traditional hoisting operations, this invention avoids the hidden dangers of rope swaying, material displacement, and inaccurate positioning that exist in traditional hoisting, improving the stability of the transfer process. After the component is in place, three sets of electric push rods are activated according to the curvature of the precast retaining wall, driving the placement plate and support base to adjust their positions. This allows the elastic clamping plate and fixed clamping plate to adapt to components of different specifications. After the position adjustment is completed, the hydraulic cylinder retracts, placing the precast retaining wall stably on the placement plate. Then, the starting motor drives the threaded rod to rotate, pushing the elastic clamping plate to cooperate with the fixed clamping plate to clamp the precast retaining wall, firmly fixing the component and effectively improving the stability of the overall assembly operation.

[0017] 3. In this invention, after the prefabricated retaining wall is connected to the arch beam, workers tighten it with bolts. The gas discharged from the exhaust pipe enters the inner cavity of the buffer plate through the connecting pipe, pushing the sliding plate and the contact plate to adhere to the side wall of the prefabricated retaining wall. After the operation is completed, motor one drives the slide, U-shaped rod and rack one to move to the right. Rack one and gear one mesh intermittently. Linkage gear two and rack two drive the clamping component to move to the left and stretch spring two. After disengagement, spring two rebounds, causing the component to hit the prefabricated retaining wall. If the bolts are not tightened properly, the retaining wall will shake, squeezing the gas inside the buffer plate and causing air pressure changes. The air pressure sensor monitors the air pressure in real time. When the value exceeds the standard, the pressure relief valve is opened, and the airflow sends an alarm through the whistle, reminding workers to re-inspect and tighten the bolts in time. This structure can quickly check for loose bolts, eliminate construction hazards, and ensure that the assembled structure is firmly connected. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] See Figures 1 to 9 As shown, the present invention provides a construction device for assembling an arched structure using prefabricated retaining walls, including a vehicle body 1, an arc-shaped plate 2 mounted on the vehicle body 1, and a support 3 mounted on one side of the arc-shaped plate 2, and further including: The gripping component includes a track 41 fixed on the vehicle body 1, a slide seat 42 slidably mounted on the track 41, a hydraulic cylinder 45 fixed on the top of the slide seat 42, a crossbeam 46 fixed at the output end of the hydraulic cylinder 45, and a hydraulic gripper 48 connected to one side of the crossbeam 46 via a connecting column 47. The assembly includes a circular plate 51 that slides on an arc plate 2, a rotating plate 53 that is rotatably connected to the circular plate 51, a support base 54 that is fixed on the rotating plate 53, a placement plate 56 that slides on the support base 54, a threaded rod 57 that is rotatably provided inside the placement plate 56, an elastic clamping plate 58 that is threadedly engaged on the threaded rod 57, and a fixed clamping plate 59 that cooperates with the elastic clamping plate 58 that is fixed on the placement plate 56. It should be noted that, for reference Figures 1 to 4As shown, during the assembly of the precast retaining wall, the workers first place the precast retaining wall on the support 3, then move the vehicle 1 to the installation position and park it in the center between the two sets of precast retaining walls. Then, motor 43 is started, its output shaft driving roller 44 to roll to the right along track 41. After the two hydraulic grippers 48 move above the precast retaining wall, motor 43 is turned off. Next, hydraulic cylinder 45 is started, its output end retracting inward, driving the two hydraulic grippers 48 downward until they clamp the precast retaining wall. Then, hydraulic cylinder 45 is operated again, its output end extending upward, lifting the hydraulic grippers 48 and the clamped precast retaining wall together. Then, motor 43 is started in reverse, driving roller 44 to rotate, causing the hydraulic grippers 48 to carry the precast retaining wall to the left to the installation position. Compared to traditional hoisting operations, this method avoids the hidden dangers of rope swaying, material displacement, and inaccurate positioning that exist in traditional hoisting, improving the stability of the transportation process. After the hydraulic gripper 48 moves above the placement plate 56, the workers activate three sets of electric push rods 55 according to the curvature of the precast retaining wall. The electric push rods 55 drive the three sets of placement plates 56 to move along the axis of the rotating plate 53, and at the same time drive the support base 54 to move synchronously. This allows the support range of the elastic clamping plate 58 and the fixed clamping plate 59 to be adapted to the specifications of the precast retaining wall to be assembled. This allows for flexible adjustment of the support points for precast retaining walls with different curvatures, resulting in stronger adaptability. Then, the output end of the hydraulic cylinder 45 is controlled to retract, and the precast retaining wall is placed stably on the surface of the placement plate 56. Then, the motor 2 52 is started to drive the threaded rod 57 to rotate. Through the transmission of the threaded rod 57, the elastic clamping plate 58 moves towards the fixed clamping plate 59 and clamps the precast retaining wall, thereby providing support for the precast retaining wall and improving the stability of the precast retaining wall assembly.

[0022] The buffer assembly includes an arc-shaped rod 61 fixed to one side of the arc-shaped plate 2, a connecting rod 62 slidably disposed on the arc-shaped rod 61, a buffer plate 63 fixed to one end of the connecting rod 62, a buffer cylinder 64 fixed on the arc-shaped plate 2, a piston rod 65 slidably disposed inside the buffer cylinder 64, one end of the piston rod 65 being connected to the connecting rod 62, and an exhaust pipe 66 communicating with the side wall of the buffer cylinder 64. The adjustment assembly includes an exhaust pipe 72 connected to one end of the exhaust pipe 66, a plurality of exhaust holes 73 are provided on the side wall of the exhaust pipe 72, and a block 76 is slidably provided inside the exhaust pipe 72; It should be noted that, for reference Figures 4 to 7As shown, after the precast retaining wall is clamped, when assembling the precast retaining wall and the arch beam, the motor 3 510 is started. The motor 3 510 drives the rotating plate 53 to rotate, which drives the support seat 54, the placement plate 56 and the precast retaining wall to flip up to the top of the arch beam. When the support seat 54 rotates to the specified angle, it will contact the buffer plate 63 and compress it, causing the buffer plate 63 to move downward. At the same time, it drives the connecting rod 62 to slide along the outer wall of the arc rod 61. During the movement of the connecting rod 62, it will compress the first spring to achieve the first-level buffer and push the piston rod 65 to slide inside the buffer cylinder 64, compressing the gas in the cylinder. The compressed gas is discharged through the exhaust pipe 66. The second-level buffer is completed by the gas resistance. Thus, the double buffer structure effectively avoids the rigid collision between the precast retaining wall and the arch beam and prevents the components from being damaged by collision. When the slide block 42 moves to the leftmost end with the hydraulic cylinder 45, the crossbeam 46 and the hydraulic gripper 48, the rack rod 71 under the crossbeam 46 will mesh with the toothed ring 75. The buffering force can be automatically adjusted according to the curvature of the precast retaining wall. When the curvature of the precast retaining wall increases, the center of gravity of the component shifts outward and the impact speed increases. The original buffering effect cannot meet the usage requirements and the buffering capacity needs to be improved. At this time, the electric push rod 55 adjusts the support range of the placement plate 56 and the elastic clamping plate 58 to be small. The downward stroke of the hydraulic cylinder 45 drives the hydraulic gripper 48 to increase accordingly, which in turn drives the crossbeam 46 and the rack rod 71 to move down synchronously, driving the toothed ring 75 and the lead screw 74 to rotate. The lead screw 74 pushes the block block 76 to move a long distance in the exhaust pipe 72, blocking more exhaust holes 73, slowing down the gas discharge speed, and increasing the damping force inside the buffer cylinder 64. When the curvature of the precast retaining wall decreases, the center of gravity of the component shifts inward, the impact speed slows down, and the original buffering force is too large. The above-mentioned components then operate in the opposite way, reducing the number of vent holes 73 blocked, accelerating the venting speed, and reducing the damping force. This allows them to adaptively adjust the buffering strength according to the change in the curvature of the precast retaining wall, so that the buffering effect is always within a reasonable range, further ensuring the stability of the assembly operation.

[0023] The detection component is located on one side of the buffer plate 63.

[0024] In an optional embodiment, a motor 43 is mounted on the slide 42, and the output end of the motor 43 drives a roller 44, which rolls in conjunction with the track 41.

[0025] In an optional embodiment, an electric push rod 55 for driving the placement plate 56 to move is mounted on the support base 54, a second motor 52 for driving the rotating plate 53 to rotate is mounted on one side of the circular plate 51, and a third motor 510 for driving the threaded rod 57 to rotate is mounted on the bottom of the rotating plate 53.

[0026] In an optional embodiment, the arc plate 2 is provided with a groove 67, and the connecting rod 62 slides along the inside of the groove 67.

[0027] In an optional embodiment, the adjusting assembly further includes a rack rod 71 fixed to the bottom end of the crossbeam 46, a lead screw 74 rotatably connected inside the exhaust pipe 72, a toothed ring 75 that meshes with the rack rod 71 is sleeved on the outside of the lead screw 74, and a plug 76 is threaded onto the outer wall of the lead screw 74.

[0028] In an optional embodiment, the detection component includes a sliding plate 81 that slides within the cavity of the buffer plate 63, a contact plate 82 fixed to one side of the sliding plate 81, the buffer plate 63 having a hollow internal structure, a connecting pipe 83 connecting the buffer plate 63 and the exhaust pipe 72, a vent pipe 84 connecting the side wall of the buffer plate 63, a whistle 85 installed at the open end of the vent pipe 84, a pressure relief valve 86 installed on the outer wall of the vent pipe 84, and a pressure sensor 87 installed within the cavity of the buffer plate 63, the pressure sensor 87 being connected to the pressure relief valve 86 via a signal connection.

[0029] In an optional embodiment, the detection assembly further includes a housing 811 fixed to the vehicle body 1. A rotating rod 812 is rotatably mounted inside the housing 811. Gear 813 is mounted on both ends of the rotating rod 812 via one-way bearings. Gear 814 is fixedly mounted at the center of the rotating rod 812. A U-shaped rod 88 is fixed on one side of the slide block 42. A rack 89 that intermittently meshes with gear 813 is fixed on the U-shaped rod 88. A rack 810 that meshes with gear 814 is slidably mounted inside the housing 811. The end of rack 810 is connected to the circular plate 51.

[0030] It should be noted that, for reference Figures 7 to 9As shown, after the precast retaining wall and the arch beam are connected, the workers use bolts to fasten them together. The gas discharged from the exhaust pipe 72 is introduced into the inner cavity of the buffer plate 63 through the connecting pipe 83. The air pressure pushes the sliding plate 81 to move, which in turn causes the contact plate 82 to press tightly against the side wall of the precast retaining wall. After the installation process is completed, the motor 43 is started. The motor 43 drives the roller 44 and the slide block 42 to move to the right. The slide block 42 simultaneously drives the U-shaped rod 88 and the rack 89 to move together. The rack 89 with segmented teeth will intermittently mesh with the gear 813. When the two mesh, the rack 89 drives the gear 813, the rotating rod 812 and the gear 814 to rotate synchronously. The gear 814 then drives the rack 810 to move in the opposite direction, which finally drives the circular plate 51, the support base 54, the placement plate 56, the elastic clamp 58 and the fixed clamp 59 to move to the left as a whole. During this process Spring 2 is stretched and stores force; when rack 1 89 disengages from gear 1 813, spring 2 rebounds and resets, causing the aforementioned components to return to their original positions, causing the fixed clamp 59 to impact the precast retaining wall. If the bolts between the precast retaining wall and the arch beam are not properly tightened, the impacted precast retaining wall will shake. This shaking will be transmitted to the contact plate 82, causing the sliding plate 81 to squeeze the gas in the cavity of the buffer plate 63, causing fluctuations in internal air pressure. The air pressure sensor 87 will monitor the air pressure in the cavity in real time. Once the air pressure value exceeds the preset threshold, the sensor will trigger the pressure relief valve 86 to open, and the gas in the cavity will be discharged outward along the vent pipe 84. When the airflow passes through the whistle body 85, it will emit a warning sound, thereby reminding the staff that there is a problem with the bolt installation being loose, and timely re-inspection and reinforcement work will be carried out to effectively avoid construction safety hazards caused by loose bolts and ensure the reliability of the connection of the assembled structure.

[0031] It should also be noted that when the slide block 42 drives the rack 89 to move to the right, the gear 813 will only rotate freely under the action of the one-way bearing and will not drive the rotating rod 812 and the rack 810 to rotate.

[0032] In an optional embodiment, a first spring is sleeved on the outer wall of the arc-shaped rod 61, and a second spring is fixedly connected between the arc-shaped plate 2 and the circular plate 51.

[0033] In an optional embodiment, the outer wall of the buffer cylinder 64 is connected to the suction pipe, the inside of which is equipped with a one-way valve, and the inside of the exhaust pipe 66 is equipped with a one-way valve.

[0034] Working Principle: It should be noted that during the assembly of the precast retaining wall, workers first place the precast retaining wall on the support 3, then move the vehicle 1 to the installation position and park it in the center between the two sets of precast retaining walls. Then, motor 43 is started, its output shaft driving roller 44 to roll to the right along track 41. Once the two hydraulic grippers 48 move above the precast retaining wall, motor 43 is turned off. Next, hydraulic cylinder 45 is started, its output end retracting inward, driving the two hydraulic grippers 48 downward until they clamp the precast retaining wall. Then, hydraulic cylinder 45 is operated again, its output end extending upward, lifting the hydraulic grippers 48 and the clamped precast retaining wall together. Then, motor 43 is started in reverse, driving roller 44 to rotate, causing the hydraulic grippers 48 to carry the precast retaining wall to the left to the installation position. Compared to traditional hoisting operations, this method avoids the hidden dangers of rope swaying, material displacement, and inaccurate positioning that exist in traditional hoisting, improving the stability of the transportation process. After the hydraulic gripper 48 moves above the placement plate 56, the workers activate three sets of electric push rods 55 according to the curvature of the precast retaining wall. The electric push rods 55 drive the three sets of placement plates 56 to move along the axis of the rotating plate 53, and at the same time drive the support base 54 to move synchronously. This allows the support range of the elastic clamping plate 58 and the fixed clamping plate 59 to be adapted to the specifications of the precast retaining wall to be assembled. This allows for flexible adjustment of the support points for precast retaining walls with different curvatures, resulting in stronger adaptability. Then, the output end of the hydraulic cylinder 45 is controlled to retract, and the precast retaining wall is placed stably on the surface of the placement plate 56. Then, the motor 2 52 is started to drive the threaded rod 57 to rotate. The threaded rod 57 drives the elastic clamping plate 58 to move towards the fixed clamping plate 59 and clamp the precast retaining wall, thereby providing support for the precast retaining wall and improving the stability of the precast retaining wall assembly. It should be noted that after the precast retaining wall is clamped, when assembling the precast retaining wall and the arch beam, the motor 3 510 is started. The motor 3 510 drives the rotating plate 53 to rotate, which drives the support seat 54, the placement plate 56 and the precast retaining wall to flip together towards the top of the arch beam. When the support seat 54 rotates to the specified angle, it will contact the buffer plate 63 and compress it, causing the buffer plate 63 to move downward. At the same time, it drives the connecting rod 62 to slide along the outer wall of the arc rod 61. During the movement of the connecting rod 62, it will compress the first spring to achieve the first-level buffer and push the piston rod 65 to slide inside the buffer cylinder 64, compressing the gas in the cylinder. The compressed gas is discharged through the exhaust pipe 66. The second-level buffer is completed by the gas resistance. Thus, the double buffer structure effectively avoids the rigid collision between the precast retaining wall and the arch beam and prevents the components from being damaged by collision. When the slide block 42 moves to the leftmost end with the hydraulic cylinder 45, the crossbeam 46 and the hydraulic gripper 48, the rack rod 71 under the crossbeam 46 will mesh with the toothed ring 75. The buffering force can be automatically adjusted according to the curvature of the precast retaining wall. When the curvature of the precast retaining wall increases, the center of gravity of the component shifts outward and the impact speed increases. The original buffering effect cannot meet the usage requirements and the buffering capacity needs to be improved. At this time, the electric push rod 55 adjusts the support range of the placement plate 56 and the elastic clamping plate 58 to be small. The downward stroke of the hydraulic cylinder 45 drives the hydraulic gripper 48 to increase accordingly, which in turn drives the crossbeam 46 and the rack rod 71 to move down synchronously, driving the toothed ring 75 and the lead screw 74 to rotate. The lead screw 74 pushes the block block 76 to move a long distance in the exhaust pipe 72, blocking more exhaust holes 73, slowing down the gas discharge speed, and increasing the damping force inside the buffer cylinder 64. When the curvature of the precast retaining wall decreases, the center of gravity of the component shifts inward and the impact speed slows down. The original buffering force is too large. The above components then operate in the opposite way, reducing the number of vent holes 73 blocked, accelerating the venting speed, and reducing the damping force. This allows the buffering strength to be adaptively adjusted according to the change in the curvature of the precast retaining wall, so that the buffering effect is always within a reasonable range, further ensuring the stability of the assembly operation. It should be noted that after the precast retaining wall and the arch beam are connected, the workers use bolts to tighten them. The gas discharged from the exhaust pipe 72 will enter the inner cavity of the buffer plate 63 through the connecting pipe 83. The air pressure will push the sliding plate 81 to move, thereby causing the contact plate 82 to press tightly against the side wall of the precast retaining wall. After the installation process is completed, the motor 43 is started. The motor 43 drives the roller 44 and the slide 42 to move to the right. The slide 42 simultaneously drives the U-shaped rod 88 and the rack 89 to move together. The rack 89 with segmented teeth will form an intermittent meshing state with the gear 813. When the two mesh, the rack 89 drives the gear 813, the rotating rod 812 and the gear 814 to rotate synchronously. The gear 814 then drives the rack 810 to move in the opposite direction, finally causing the circular plate 51, the support 54, the placement plate 56, the elastic clamp 58 and the fixed clamp 59 to move to the left as a whole. During the process, spring 2 is stretched and stores energy; when rack 1 89 disengages from gear 1 813, spring 2 rebounds and resets, causing the aforementioned components to return to their original positions, causing the fixed clamp 59 to impact the precast retaining wall. If the bolts between the precast retaining wall and the arch beam are not properly tightened, the impacted precast retaining wall will shake. This shaking will be transmitted to the contact plate 82, causing the sliding plate 81 to squeeze the gas in the cavity of the buffer plate 63, causing fluctuations in internal air pressure. The air pressure sensor 87 will monitor the air pressure in the cavity in real time throughout the process. Once the air pressure value exceeds the preset threshold, the sensor will trigger the pressure relief valve 86 to open, and the gas in the cavity will be discharged outward along the vent pipe 84. When the airflow passes through the whistle body 85, it will emit a warning sound, thereby reminding the staff that there is a problem with the bolt installation being loose, and timely re-inspection and reinforcement work will be carried out to effectively avoid construction safety hazards caused by loose bolts and ensure the reliability of the connection of the assembled structure.
