Technical Field

[0001] The utility model relates to the technical field of escape passages, and in particular to a height-adjustable escape passage. Background Art

[0002] Tunnel escape routes are crucial safety features during tunnel construction, primarily used for the emergency evacuation of workers in the event of a tunnel collapse. Currently, tunnel escape routes primarily utilize hollow pipes, installed section by section and connected to form a single, integrated escape structure. Existing paved escape routes utilize various connection structures and automated devices, enabling frequent movement and installation. However, these routes utilize crawler tracks for overall movement, which, while capable of navigating complex terrain, lack the flexibility required due to the lack of height adjustment. Utility Model Content

[0030] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, they can also be understood as further technical solutions without paying creative work. In some figures, components with the same structure or function are schematically illustrated, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0031] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0032] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0033] Reference Figures 1 to 4 , which is the first embodiment of the utility model, proposes a height-adjustable escape passage, including: a passage body 1; a plurality of adjustment seats 2, which are arranged on the passage body 1; an adjustment crank 3 rotatably arranged on the adjustment seat 2; a plurality of wheels 4, which are rotatably arranged at both ends of the adjustment crank 3. When the adjustment crank 3 rotates, the height of the wheel 4 relative to the adjustment seat 2 changes.

[0034] In this embodiment, the height of the wheels 4 is adjusted by rotating the crank 3. This allows the escape route to flexibly adjust its height based on the actual conditions of complex terrain, significantly improving its maneuverability and adaptability in various terrain conditions. This effectively addresses the problem of existing escape routes being unable to adjust their height and lacking flexibility in handling complex terrain. The adjustable height of the wheels 4 ensures that the route body 1 remains stable on uneven ground, preventing the route from tilting or jolting, providing a stable walking environment for escapees, reducing the risk of falls and injuries caused by an unstable route, and improving escape safety. When encountering raised terrain, the wheels 4 can be lowered to facilitate smooth passage. When encountering sunken terrain, the wheels 4 can be raised to prevent damage to the bottom of the route from contacting the ground, thereby extending the service life of the escape route. This height-adjustable design reduces the need for terrain modification during the route installation process, reduces construction difficulty and costs, and improves installation efficiency. In emergency escape situations, the route height can be quickly adjusted to adapt to sudden terrain changes, ensuring an unobstructed escape route and buying valuable time for evacuation.

[0035] As a further technical solution, it also includes: there are several gears 5, which are arranged on the adjusting crank 3; the locking block 6 is raised and lowered on the adjusting seat 2, and the locking block 6 has several teeth 7, which cooperate with the gear 5. After the locking block 6 slides, it locks or cancels the rotation of the gear 5.

[0036] In this embodiment, the gear 5 rotates synchronously with the adjustment crank 3 and, in conjunction with the liftable locking block 6, precisely locks or unlocks the rotation of the adjustment crank 3, thereby achieving fixed and adjustable height of the wheel 4. This ensures that the escape passage remains stable at the set height when the wheel 4 height needs to be maintained, enhancing the passage's stability and reliability during use. The design of the locking block 6 effectively prevents the adjustment crank 3 from accidentally rotating due to vibration or external factors during use, which could cause the wheel 4 height to change, thus preventing instability in the escape passage and providing greater safety for evacuees. When the wheel 4 height needs to be adjusted, the gear 5 is unlocked by operating the locking block 6, and then locked again after adjustment is complete. This simple and convenient operation allows for quick locking and unlocking of the wheel 4 height, improving the efficiency of escape passage deployment and adjustment in complex terrain. This locking mechanism can withstand heavy loads and impacts, maintaining the wheel 4 height even when crowded with evacuees or subjected to external forces, ensuring the normal use of the escape passage. The cooperation between the gear 5 and the locking block 6 increases the accuracy and controllability of the height adjustment, and can achieve subtle adjustment of the height of the wheel 4 to adapt to more complex and precise terrain requirements, further improving the terrain adaptability of the escape passage.

[0037] As a further technical solution, it also includes: there are several telescopic members 8, which are arranged on the adjustment seat 2, and the locking block 6 is arranged on the adjustment seat 2 through the telescopic members 8, and the telescopic members 8 are used to drive the locking block 6 to rise and fall.

[0038] In this embodiment, the arrangement of the telescopic member 8 provides stable and reliable power for the raising and lowering of the locking block 6, ensuring that the locking block 6 can accurately and quickly complete the raising and lowering action, achieving the locking and unlocking operation of the gear 5, and improving the response speed and operational efficiency of the entire height adjustment system. The telescopic member 8 can precisely control the raising and lowering stroke of the locking block 6, making the locking block 6 and the gear 5 fit more tightly and accurately, enhancing the reliability of the locking, and avoiding the situation of loose locking or misoperation. The multiple telescopic members 8 are evenly distributed and act together on the locking block 6, so that the locking block 6 is evenly stressed and moves smoothly during the raising and lowering process, reducing the possibility of jamming and skewness, and further improving the stability and reliability of the system.

[0039] As a further technical solution, the gear 5 has several through holes 9 and also includes: a locking rod 10 slidably set on the adjustment seat 2, and the locking rod 10 slides into or out of the through hole 9, and the locking rod 10 is used to lock the gear 5 from rotating.

[0040] In this embodiment, the through-hole 9 on the gear 5 cooperates with the slidable locking rod 10, providing additional protection for locking the gear 5. When the locking rod 10 slides into the through-hole 9, it can more firmly restrict the rotation of the gear 5, further enhancing the locking effect on the height of the wheel 4, ensuring that the height of the wheel 4 will not change unexpectedly in complex environments, and improving the stability and safety of the escape route. This dual locking structure makes the height adjustment system more reliable. Even in extreme situations, such as when the locking block 6 fails or becomes loose, the locking rod 10 can still function, providing redundant protection for maintaining the height of the escape route. The sliding design of the locking rod 10 is simple and straightforward to operate, allowing for quick locking and unlocking of the gear 5, improving the efficiency and convenience of height adjustment. The multiple through-holes 9 are evenly distributed on the gear 5, allowing the locking rod 10 to lock the gear 5 at different positions, increasing the flexibility and precision of the locking, and better adapting to different wheel 4 height adjustment requirements.

[0041] As a further technical solution, the channel body 1 is a multi-section telescopic structure.

[0042] In this embodiment, the tunnel body 1 utilizes a multi-stage telescopic structure, allowing it to be retracted during transportation and storage, reducing space usage, facilitating handling and storage, and lowering transportation and storage costs. During tunnel construction, if the tunnel length changes or the layout of the escape route requires temporary adjustments, the multi-stage telescopic structure can quickly respond and adjust the tunnel length in a timely manner, improving construction convenience and efficiency.

[0043] As a further technical solution, it also includes: there are a plurality of guide wheels 11, which are arranged on the channel body 1, and the guide wheels 11 are used to guide the extension and retraction of the multiple sections of the channel body 1.

[0044] In this embodiment, the provision of the guide wheel 11 can effectively reduce the friction and resistance between the telescopic sections of the channel body 1, making the telescopic process smoother and easier, and reducing the difficulty of operation and labor intensity. The guide wheel 11 helps to maintain the directional accuracy of the channel body 1 during telescopic expansion and contraction, avoids offset, jamming or twisting of the telescopic section, ensures that the channel can be stably and reliably expanded and contracted, and extends the service life of the channel. The multiple guide wheels 11 are evenly distributed and share the load during expansion and contraction, making the force more uniform, reducing the risk of local wear and damage, and improving the overall stability and durability of the channel. In an emergency, the guide wheel 11 can quickly guide the channel body 1 to complete the telescopic action, saving time, improving the efficiency of the escape channel deployment, and buying more precious time for people to escape.

[0045] As a further technical solution, the adjustment seat 2 is provided with an inspection port 12 and further includes: an inspection panel 13 detachably provided on the inspection port 12 , and the inspection panel 13 is used to open or close the inspection port 12 .

[0046] In this embodiment, the adjustment seat 2 is provided with an inspection port 12 and a removable inspection panel 13, which facilitates the inspection, repair, and replacement of components within the adjustment seat 2. This eliminates the need for large-scale disassembly of the entire escape passage, reducing maintenance costs and workload. When the passage malfunctions or requires regular maintenance, the inspection panel 13 can be opened to quickly and intuitively observe the internal components, allowing problems to be promptly identified and addressed, ensuring the normal and reliable height adjustment function of the passage and improving the usability and safety of the escape passage. The removable inspection panel 13 is easy to operate and can be quickly opened for emergency repairs, shortening maintenance time and ensuring that the escape passage can be restored to normal use as soon as possible. The design of the inspection port 12 and inspection panel 13 allows maintenance personnel to operate in a relatively spacious space, improving the convenience and comfort of maintenance, and helping to improve the quality and efficiency of maintenance. When closed, the inspection panel 13 effectively prevents dust, debris, etc. from entering the adjustment seat 2, protecting the internal components from erosion and damage from the external environment and extending the service life of the components.
