Description

Technical Field

[0001] This utility model relates to the technical field of escape tunnel devices, and in particular to a novel tunnel escape tunnel device. Background Technology

[0002] Tunnel escape tunnel systems are specialized emergency passageways designed to ensure the rapid and safe evacuation of personnel during tunnel construction in response to emergencies such as collapses, water inrushes, and fires. They are typically composed of sections connected from high-strength, impact-resistant, and resilient materials (such as ultra-high molecular weight polyethylene pipes or steel pipes), and are usually laid along the tunnel face towards the secondary lining or safety exit. Some systems also include auxiliary components such as escape pods, emergency lighting, ventilation equipment, directional signage, and communication interfaces. Their core function is to provide a structurally stable and unobstructed lifeline for trapped personnel when internal tunnel passages are blocked, helping them avoid dangerous areas and quickly reach safety. They also serve as auxiliary passageways for rescue personnel to enter hazardous areas and transport supplies, making them an indispensable and crucial component of the tunnel construction safety protection system.

[0003] A search revealed Chinese patent number CN221299241U, which discloses a tunnel escape pipe device, comprising an outer pipe and an inner pipe, wherein the inner pipe is located inside the outer pipe, and an annular space is formed between the inner pipe and the outer pipe. Multiple connectors are arranged within the annular space, and a sleeve is fitted at the connection point of two outer pipes. A movable shock-absorbing mechanism is provided at the lower end of the outer pipe. This invention strengthens the connection, preventing the pipe from being broken by falling soil or rocks and the connection from fracturing in the event of an accident. Furthermore, ventilation holes are provided around the escape pipe to prevent potential oxygen deficiency during escape.

[0004] The tunnel escape pipeline devices described above have poor pipeline support stability. They often lack targeted support and fixing structures, relying only on simple splicing or basic support. When faced with vibrations, rockfalls, or slight ground subsidence in the tunnel, pipeline displacement, loosening of splices, or even overall collapse can easily occur, seriously threatening the safety of escapees. At the same time, insufficient support stability makes it difficult for the pipeline to maintain a horizontal or regular laying state, and local bending or tilting may occur. This not only affects the rapid passage of escapees, but may also cause the pipeline to deform and block the passage, delaying the escape opportunity. Utility Model Content

[0005] The purpose of this utility model is to provide a novel tunnel escape pipeline device that can solve the problems of poor pipeline support stability in the above-mentioned tunnel escape pipeline devices. These devices often lack targeted support and fixing structures and rely only on simple splicing or basic support. When faced with vibrations, rockfalls, or slight ground subsidence in the tunnel, the pipeline is prone to displacement, loosening of splices, or even overall collapse, seriously threatening the safety of escapers. At the same time, insufficient support stability makes it difficult for the pipeline to maintain a horizontal or regular laying state, and local bending or tilting may occur. This not only affects the rapid passage of escapers but may also cause the pipeline to deform and block the passage, delaying the escape opportunity.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a novel tunnel escape pipeline device, comprising a pipeline body, and further comprising:

[0007] A clamping block is disposed on the outside of the pipe body;

[0008] Support members are provided on the outer sides of both ends of the pipe body;

[0009] A clamping plate is disposed on the outer side of the middle part of the pipe body;

[0010] A clamping element is disposed at the lower middle part of the pipe body;

[0011] The support members can provide stable support for both ends of the pipe body, and by adjusting the distance between the two sets of support members, the clamping members can be linked to clamp and support the middle part of the pipe body.

[0012] In a preferred embodiment, vertical rods are disposed on the outer sides of both ends of the pipe body;

[0013] The base plate is fixedly installed on the outer side of the bottom end of the vertical rod;

[0014] The first rotating arm is rotatably mounted on the inner side of the top end of the base plate;

[0015] The second rotating arm is rotatably mounted on the outer side of the top end of the first rotating arm;

[0016] The connecting block is rotatably mounted on the inner side of the ends of the two sets of second rotating arms;

[0017] The third rotating arm is rotatably disposed inside the rotating connection between the first rotating arm and the second rotating arm;

[0018] The middle plate is rotatably mounted on the inner side of the end of the third rotating arm, and the clamping block is fixedly mounted on the upper surface of the middle plate;

[0019] A top plate is fixedly installed on the outer side of the end of the vertical rod, and another clamping block is fixedly installed on the lower surface of the top plate.

[0020] In a preferred embodiment, a telescopic cylinder is mounted on the upper surface of the base plate, and the outer side of the end of the telescopic cylinder is connected to one side of the connecting block.

[0021] In a preferred embodiment, a support strip is fixedly provided on the lower surface of the base plate, the support strip being used to increase the stability of the device.

[0022] In one preferred embodiment, the first sliding plate is fixedly disposed on one side of the middle plate;

[0023] The second sliding plate is slidably disposed on one side of the first sliding plate. One outer end of the second sliding plate is connected to another middle plate, and the inner end of the second sliding plate is slidably connected to the outer side of the clamping plate.

[0027] In a preferred embodiment, the outer end of the clamping plate has an arc-shaped structure for fitting against the outer side of the pipe body.

[0028] In a preferred embodiment, a plurality of lifting cylinders are installed on the lower surface of the end of the first sliding plate.

[0029] In a preferred embodiment, casters are mounted on the outer side of the bottom end of the lifting cylinder.

[0030] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0031] This invention, in use, utilizes a novel tunnel escape pipeline device with a linkage clamping and self-locking design, significantly improving the stability and ease of operation of the pipeline connection and providing reliable protection for tunnel escape. During use, after placing the pipeline body inside the clamping block, activating the telescopic cylinder increases its length, causing the connecting block to move vertically upwards and pushing the two second rotating arms to rotate until the second rotating arms are horizontal. At this point, the first and third rotating arms are on the same vertical axis, thereby causing the clamping blocks on both sides to clamp and fix the end of the pipeline body. Simultaneously, the design of the first and third rotating arms being on the same axis, and their 90-degree angle with the second rotating arm, effectively counteracts the inward rotational force. The self-locking function further enhances clamping stability, preventing the pipeline connection from loosening. The entire operation only requires activating the telescopic cylinder to complete the linkage clamping and self-locking, eliminating the need for complex tools. This simplifies the pipeline assembly process, facilitating rapid tunnel construction in emergency escape scenarios, and ensures the structural safety of the pipeline during escape through the robust clamping and self-locking design, reducing the risk of collapse and detachment.

[0040] 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.

[0041] Example 1:

[0042] Please see Figure 1 - Figure 6 This embodiment provides a novel tunnel escape pipeline device that can be stably supported, and its specific concept is as follows:

[0043] A novel tunnel escape pipeline device includes a pipeline body 1, and the novel tunnel escape pipeline device also includes a clamping block 2 and a support member.

[0044] Among them, the support members used to provide stable support for the pipe body 1 are set on the outer sides of both ends of the pipe body 1.

[0045] The clamping block 2 for fixing is located on the outside of the pipe body 1, and the arc-shaped structure on one side of the clamping block 2 can clamp the outside of the pipe body 1.

[0046] Among them, the support members can provide stable support for both ends of the pipe body 1, and the self-locking design of the support members can further increase the stability of the support for the pipe body 1.

[0047] As examples, in this embodiment, the support includes:

[0048] The pipe body 1 has vertical rods 201 for limiting the position on both sides, which provide a vertical positioning foundation for the entire clamping support structure. The bottom of the vertical rods 201 is fixedly connected to a base plate 202 for support, which serves as a load-bearing component at the bottom of the device. At the same time, the lower surface of the base plate 202 is fixedly connected to a support strip 210, which increases the contact area with the ground, further improving the stability of the device support and preventing it from tipping over during use.

[0049] Meanwhile, a first rotating arm 203 for connection is rotatably connected to the inner top of the base plate 202, and a second rotating arm 204 for connection is rotatably connected to the outer top of the first rotating arm 203. The inner ends of the two sets of second rotating arms 204 are rotatably connected to a connecting block 205 for connection. Furthermore, a third rotating arm 206 for connection is rotatably connected to the inner side of the rotatable connection between the first rotating arm 203 and the second rotating arm 204. The outer end of the third rotating arm 206 is rotatably connected to a middle plate 207 for support. A clamping block 2 is fixedly connected to the upper surface of the middle plate 207.

[0050] In addition, a top plate 208 is fixedly connected to the outer end of the vertical rod 201, and another clamping block 2 is fixedly connected to the lower surface of the top plate 208. The two clamping blocks 2 are vertically aligned. A telescopic cylinder 209 for driving is installed on the upper surface of the bottom plate 202. The outer end of the telescopic cylinder 209 is fixedly connected to one side of the connecting block 205. When the telescopic cylinder 209 extends or retracts, it will push the connecting block 205 to move, thereby driving the second rotating arm 204, the first rotating arm 203 and the third rotating arm 206 to rotate together, and finally driving the middle plate 207 and the lower clamping block 2 to move up and down, realizing the opening and closing with the clamping block 2 below the top plate 208, and completing the clamping or releasing operation of the pipeline.

[0051] It should be noted that when the device does not need to be moved, it can be stably supported by the support bar 210. The strip groove on the surface of the support bar 210 can increase its friction with the ground. One end of the pipe body 1 is clamped and fixed by two clamping blocks 2.

[0052] Example 2:

[0053] Please see Figure 1 - Figure 6 This embodiment provides a novel tunnel escape pipe device that can clamp the outer side of the middle part of the pipe body 1. The specific idea is as follows:

[0054] A novel tunnel escape pipeline device includes a pipeline body 1, and the novel tunnel escape pipeline device also includes a clamping plate 3 and clamping components.

[0055] The clamping plate 3 for clamping is located on the outer side of the middle part of the pipe body 1.

[0056] The clamping component used to drive the clamping plate 3 to move is located in the lower middle part of the pipe body 1.

[0057] As some examples, in this embodiment, the clamping element includes:

[0058] The first sliding plate 301, which serves as a connector, is fixedly connected to one side of the middle plate 207.

[0059] The second sliding plate 302, which serves as a connector, is slidably connected to one side of the first sliding plate 301.

[0060] It should be noted that one outer end of the second sliding plate 302 is fixedly connected to another middle plate 207, and the inner end of the second sliding plate 302 is slidably connected to the outer side of the clamping plate 3.

[0061] The first sliding plate 301 has a first toothed groove 303 on its inner side for connecting, providing a meshing basis for gear transmission; the lower surface of the second sliding plate 302 is rotatably connected to a gear 304 for connecting, and the inner side of one end of the clamping plate 3 has a second toothed groove 305. The gear 304 meshes with the first toothed groove 303 and the second toothed groove 305 respectively, forming a linkage transmission structure. When the first sliding plate 301 moves, the meshing action of the gear 304 can drive the second sliding plate 302 and the clamping plate 3 to move synchronously.

[0062] In addition, the outer end of the clamping plate 3 is designed with an arc-shaped structure, which can better fit the outer curved surface of the pipe body 1 and enhance the clamping and fixing effect on the pipe; multiple sets of lifting cylinders 306 for support are installed on the lower surface of the end of the first sliding plate 301, and casters 307 are installed on the outer bottom end of the lifting cylinder 306, which enables the device to move, greatly improves its flexibility of use, and facilitates transfer between different working positions.

[0063] Working principle:

[0064] When using this device, the user can place the pipe body 1 inside the clamping block 2. At this time, the user can activate the telescopic cylinder 209, increasing its length and causing the connecting block 205 to move vertically upwards. Simultaneously, the connecting block 205 pushes the two second rotating arms 204 to rotate. The rotation of the second rotating arms 204 pushes the rotating connection between the first rotating arm 203 and the third rotating arm 206 until the connecting block 205 pushes the two second rotating arms 204 to a horizontal position. At this point, the first rotating arm 203 and the third rotating arm 206 are positioned on the same vertical axis. At this time, the first rotating arm 203 and the third rotating arm 206 will drive the middle plate 207 to move vertically upward while rotating, thereby driving the clamping block 2 on one side of the middle plate 207 and the clamping block 2 on the one side of the top plate 208 to clamp and fix the end of the pipe body 1. By the fact that the first rotating arm 203 and the third rotating arm 206 are on the same axis and the first rotating arm 203 and the third rotating arm 206 are designed to be at a 90-degree angle to the second rotating arm 204, the force of the first rotating arm 203 and the third rotating arm 206 rotating inward can be counteracted. Through this self-locking design, the stability of the clamping block 2 clamping the pipe body 1 is further increased.

[0065] This novel tunnel escape pipeline device significantly improves the stability and ease of operation of the pipeline connection through a linkage clamping and self-locking design, providing reliable protection for tunnel escape. In use, after placing the pipeline body 1 inside the clamping block 2, the telescopic cylinder 209 is activated to increase its length, which drives the connecting block 205 to move vertically upward and pushes the two second rotating arms 204 to rotate until the second rotating arms 204 are in a horizontal state. At this time, the first rotating arm 203 and the third rotating arm 206 are on the same vertical axis, thereby driving the clamping blocks 2 on both sides to clamp and fix the end of the pipeline body 1. At the same time, the design of the first rotating arm 203 and the third rotating arm 206 on the same axis, as well as the structure of the two and the second rotating arm 204 at a 90-degree angle, can effectively counteract the inward rotation force. The self-locking function further enhances the clamping stability and prevents the pipeline connection from loosening. The entire operation only requires activating the telescopic cylinder 209 to complete the linkage clamping and self-locking, without the need for complicated tools. This simplifies the pipeline assembly process, facilitates the rapid construction of passages in emergency escape scenarios, and ensures the structural safety of the pipeline during the escape process through the stable clamping and self-locking design, reducing the risk of collapse and detachment.

[0066] Meanwhile, when using the device, the user can increase the distance between the support members on both sides and pull the first sliding plate 301 and the second sliding plate 302 to move to both sides. When the first sliding plate 301 moves, it will drive the gear 304 to rotate through the first tooth groove 303. When the gear 304 rotates, it will drive the clamping plates 3 on both sides to clamp inward. The arc-shaped structure on one side of the clamping plate 3 can fix the outer side of the middle part of the pipe body 1. At the same time, the lifting cylinder 306 can drive the caster 307 to move vertically downward, thus moving the device. By shortening the lifting cylinder 306, the device can be supported by the support bar 210, increasing the stability of the device.

[0067] This new tunnel escape pipeline device, based on the original clamping and fixing design, further enhances its applicability and stability through adjustable support and movable design. Users can increase the distance between the support members on both sides. When the first sliding plate 301 and the second sliding plate 302 are pulled to the sides, the first sliding plate 301 drives the gear 304 to rotate through the first tooth groove 303, causing the clamping plates 3 on both sides to clamp inwards. Its arc-shaped structure can fix the outer middle part of the pipeline body 1, enhancing the overall stability of the pipeline. Simultaneously, the device can be moved by the lifting cylinder 306 driving the casters 307 to move vertically downwards, meeting the deployment needs of different locations. Shortening the lifting cylinder 306 and using the support bar 210 to support the device further improves its stability when stationary. This design expands the device's adaptability to different environments, facilitating flexible adjustment of the support range according to the tunnel space, while also considering both ease of movement and stability when stationary, providing dual protection for the rapid construction and safe use of escape routes.

[0068] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
