Description

Technical Field

[0001] This utility model relates to the field of tunnel escape technology, specifically to an emergency rescue and protection device for tunnel escape pipelines. Background Technology

[0002] During the excavation of tunnel projects, escape passages need to be set up between the tunnel face and the secondary lining. In the event of a collapse of the tunnel face, the escape passage provides a relatively safe evacuation route for personnel, helping them to quickly evacuate from the danger zone and minimizing casualties.

[0003] Currently, Chinese patent CN218644331U discloses a tunnel escape passage, relating to the field of tunnel construction technology. It addresses the issue that when installing an escape passage, if the road surface is sloping or has potholes, adjacent ends cannot be completely fitted together during assembly. The escape passage comprises a cylindrical body with a connecting anchor rod at one end and a sealing cap at the other. A displacement base is located below the cylindrical body, and a support bracket is located on top of the displacement base. The displacement base is connected to the cylindrical body via the support bracket. A lifting screw is located on top of the displacement base, and the top of the displacement base is connected to the support bracket via the lifting screw. A hinge shaft is located on top of the lifting screw. A sliding groove is located at the bottom of the support bracket, which engages with the hinge shaft. A connecting rod is threaded through the middle of the base. Limiting components are located on both sides of the middle of the support bracket via the hinge shaft, and these limiting components rotate about the hinge shaft.

[0004] The aforementioned tunnel escape passages still have some problems in use. Although they can solve the problem that if the road surface is sloping or has potholes during installation, the adjacent ends of the escape passages cannot be completely fitted together when splicing. However, during escape, people at the entrance of the tunnel and in the vicinity may face the risk of being hit by falling rocks, flying objects, etc. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-4 This embodiment provides an emergency rescue and protection device for tunnel escape pipelines, including an escape pipeline assembly for personnel evacuation. A refuge room 100 is provided at the entrance of the escape pipeline assembly, and an escape hole 103 is provided on the rear side of the refuge room 100. The inner cavity of the escape hole 103 is connected to the escape pipeline assembly. A sealing component is provided at the entrance of the refuge room 100 to seal the entrance of the refuge room 100 and prevent dust in the environment from entering the room. Through the setting of the refuge room 100 and the combination of the refuge room 100 and the escape pipeline assembly, the refuge room 100 is first used to provide personnel with a temporary shelter space to prevent the harm of dust, falling rocks and flying objects. After the environment is safe, evacuation can be carried out through the escape pipeline assembly, avoiding direct exposure of personnel in harsh environments and ensuring evacuation safety.

[0033] The refuge house 100 is made of L-angle steel and steel plate welded together, and is equipped with signboard 101 and reflective strip 102 to facilitate emergency evacuation of personnel.

[0034] The enclosure includes a housing 400 fixedly connected to the inner wall of the top of the entrance of the refuge house 100. A connecting rod 404 is rotatably connected to the inner cavity of the housing 400. A shielding cloth 403 is wrapped around the surface of the connecting rod 404. The bottom of the shielding cloth 403 penetrates the housing 400 downwards and is fixedly connected to a pull plate 402. A limiting member for limiting the pull plate 402 is provided on the surface of the pull plate 402. Limiting members are provided on both sides of the entrance of the refuge house 100 and on the front and rear sides of the pull plate 402. The system includes a guide for guiding the pull plate 402. Behind the guide is a pressing assembly for securing the covering cloth 403 when it covers the entrance of the refuge house 100. With the sealing assembly in place, the collapse will generate a large amount of dust and falling debris. The covering cloth 403 can block these outside the refuge house 100, preventing dust from entering the house and affecting people's breathing, and avoiding debris from blocking the entrance or injuring people. This provides people with a relatively clean and safe space.

[0035] Among them, the shielding cloth 403 is one or more of the following composite materials: high-strength polyester fiber, fireproof canvas, and PVC coated cloth.

[0036] Among them, the guide is fixedly connected to two limiting strips 401 on both sides of the inner wall at the entrance of the refuge house 100. The four limiting strips 401 are arranged in a rectangle. The two ends of the pull plate 402 are slidably connected to the two sets of limiting strips 401 on the corresponding sides. The front of the two sets of limiting strips 401 on the rear side are both set with notches. Through the setting of the guide, the four limiting strips 401 are arranged in a rectangle to accurately guide the pull plate 402, ensuring that the pull plate 402 can only slide up and down in the vertical direction, avoiding the pull plate 402 from deviating or getting stuck during the sliding process, ensuring that the shielding cloth 403 can be smoothly unfolded and retracted, and maintaining the normal operation of the sealing component.

[0037] The crimping assembly includes pressure plates 502 respectively disposed within the recesses of the rear limiting strips 401. Each of the two sets of rear limiting strips 401 is fixedly connected to a fixing nut 500 at its rear center. The inner cavity of each of the two sets of fixing nuts 500 is threaded with a hand-tightening bolt 501. The ends of the two sets of hand-tightening bolts 501 respectively penetrate the corresponding side limiting strips 401 and are fixedly connected to an adapter rod 503. The ends of the two sets of adapter rods 503 are rotatably inserted into the surface of the corresponding side pressure plate 502. The crimping assembly... The setup allows the hand-tightened bolt 501 to move the pressure plate 502, adjusting the tightness of the shielding cloth 403 as needed. This effectively fills the gap between the shielding cloth 403 and the entrance of the refuge house 100, further preventing dust from entering. Compared to relying solely on the shielding cloth 403, the sealing effect is significantly improved. Furthermore, the design of the hand-tightened bolt 501 facilitates manual adjustment by operators without the need for additional tools, allowing for quick tightening and loosening of the pressure plate 502, and making it convenient to close and open the entrance of the refuge house 100.

[0038] The limiting components are respectively opened in square grooves 405 inside both sides of the pull plate 402. The inner cavities of the two sets of square grooves 405 are slidably connected to connecting plates 406. The rear sides of the opposite ends of the two sets of connecting plates 406 are fixedly connected to round rods 407. The front upper and lower parts of the two sets of limiting strips 401 located on the rear side are provided with slots 412 for the round rods 407 to be inserted. The rear sides of the opposite ends of the two sets of connecting plates 406 are fixedly connected to connecting pieces 411. The ends of the two sets of connecting pieces 411 are... Each part extends backward through the pull plate 402 and is fixedly connected to a set of push plates 408. The rear side of the pull plate 402 is provided with a reset component that pushes the push plate 408 outward to drive the round rod 407 into the slot 412. Through the setting of the limiting member, the reset component can automatically insert the round rod 407 into the slot 412 to lock the pull plate 402 without manual operation, ensuring that the shielding cloth 403 will not move by itself due to external force in the closed state, and maintaining the closed effect of the shelter 100.

[0039] The reset component is fixedly connected to the rear side of the pull plate 402 and the guide rods 409 corresponding to the ends of the push plate 408. A reset spring 410 is sleeved on the surface of the guide rods 409 located between the push plate 408 and the pull plate 402. Both the push plate 408 and the pull plate 402 have operating holes 413. The two sets of operating holes 413 are aligned. The operating holes 413 are used to push the push plate 408 with external force to unlock and lock the limiting component. The reset component provides a stable elastic force for the insertion and withdrawal of the round rod 407, ensuring that the limiting component can reliably switch between the unlocked and locked states. It is not easy to fail after long-term use and ensures the stable function of the sealing component. At the same time, the operating holes 413 allow the operator to intuitively and conveniently apply force to the push plate 408 to unlock and lock the limiting component, reducing the difficulty of operation and enabling quick operation even in a chaotic emergency.

[0040] One end of the connecting rod 404 is fixedly connected to the transmission rod 201. The end of the transmission rod 201 passes through the housing 400 and the shelter 100 in sequence and is fixedly connected to the turntable 200. With the turntable 200 and the transmission rod 201, the shielding cloth 403 can be easily rolled up by rotating the turntable 200, so that the shielding cloth 403 can be rolled into the housing 400.

[0041] The escape pipe assembly includes an escape pipe 302 connected to the escape hole 103. The other end of the escape pipe 302 extends into the secondary lining structure of the tunnel. Through the installation of the escape pipe 302, the escape pipe 302 is connected to the escape hole 103 and extends into the secondary lining structure of the tunnel, providing personnel with a clear and fixed evacuation route, avoiding personnel from falling into danger due to not being able to find the escape direction in an emergency. At the same time, the escape pipe 302 isolates personnel from the external dangerous environment, preventing personnel from being injured by dust, collapse objects, etc. during the evacuation process. Meanwhile, the secondary lining structure of the tunnel is relatively strong, providing a relatively safe destination for personnel evacuation.

[0042] The escape pipe 302 is made of ultra-high molecular weight polyethylene.

[0043] The escape pipe 302 has multiple sets of trusses 300 arranged sequentially on its surface. The escape pipe 302 passes through the inner cavity of the truss 300 and its outer surface contacts the inner wall of the truss 300. Through the arrangement of the trusses 300, the trusses 300 tightly wrap the escape pipe 302. When it is subjected to external impact, it can disperse the impact force, prevent the pipe from deforming or breaking, and ensure that the escape passage remains unobstructed in an emergency.

[0044] Among them, the truss 300 is a protective truss 300 welded from H-beams. The cross section of the truss 300 is rectangular, and reflective strips 102 are affixed to the surface of the truss 300.

[0045] In this system, two adjacent sets of trusses 300 are connected together by chains 301. The chains 301 connect adjacent trusses 300, making the structure of the entire escape tunnel group more compact. When a certain part is subjected to external force, other trusses 300 can disperse the force through the chains 301, avoiding local damage that could affect the safety of the overall escape passage. Furthermore, the chain 301 connection method is simple, facilitating the installation, disassembly, and replacement of trusses 300. During routine maintenance or emergency repairs, individual trusses 300 can be operated quickly without affecting the normal use of other parts.

[0046] Working principle;

[0047] In the event of an emergency such as a collapse or fire, people should quickly enter the refuge house through the entrance.

[0048] After personnel enter the refuge house 100, they reach their hands into the operating hole 413 and push the push rod outward, thereby pushing the push plate 408 to overcome the elastic force of the return spring 410, causing the round rod 407 to be pulled out of the slot 412. At this time, the shielding cloth 403 is manually pulled down, causing the pull plate 402 to slide down. When the bottom of the pull plate 402 contacts the bottom inner wall of the refuge house 100, the push plate 408 is released, and under the action of the return spring 410, the round rod 407 is inserted into the slot 412.

[0049] At this time, turn the hand-tightening bolt 501. The hand-tightening bolt 501 drives the pressure plate 502 to move towards the edge of the shielding cloth 403 through the adapter rod 503, thereby interfering with the pressing of the shielding cloth 403. The pressing assembly further fixes the shielding cloth 403, seals the entrance of the refuge house 100, and prevents dust from entering.

[0050] Finally, personnel enter the escape pipe 302 through the escape hole 103 and evacuate into the secondary lining structure of the tunnel along the escape pipe 302. Due to the truss 300 and connecting chain 301 installed on the surface of the escape pipe 302, the structural stability and safety of the escape pipe 302 can be guaranteed to a certain extent during the personnel evacuation process.

[0051] When the surrounding environment is safe, the push rod is pushed outward through the operating hole 413, thereby disengaging the end of the round rod 407 from the slot 412 located below. Then, the turntable 200 is rotated, and the connecting rod 404 is rotated through the transmission rod 201, thereby causing the shielding cloth 403 to be rolled up to the surface of the connecting plate 406. At the same time, the pull plate 402 is moved upward. When the end of the round rod 407 is aligned with the opening of the slot 412 located above, the return spring 410, through the transmission of the push plate 408, the connecting piece 411, and the connecting plate 406, engages the end of the round rod 407 into the slot 412.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
