[0002] A tunnel escape house is an emergency refuge facility specifically designed for tunnel environments. It is usually installed in the side walls or connecting passages of a tunnel to provide temporary safety shelter for trapped people in the event of sudden disasters such as fires, traffic accidents, or toxic gas leaks, allowing them to await rescue or carry out self-rescue. Its core functions are to isolate the dangerous environment, provide survival conditions, and guide safe evacuation.

[0003] According to the published patent CN221882987U: An escape tube impact test device includes a pipe detection section and a heavy hammer action section set above the pipe detection section. The pipe detection section is also equipped with a monitoring and acquisition section. The test device provides accurate test data, has no height limit, and can simulate a variety of different working conditions. However, it still has the following disadvantages to a certain extent.

[0004] However, this utility model has the following problems in actual use:

[0005] 1. The original device uses a fixed-shape hammer head, which can only simulate a single type of impact object (such as rocks or falling trees). It cannot cover irregularly shaped impact objects (such as sharp rocks or reinforced concrete blocks) that may occur in scenarios such as tunnel collapses or landslides, which will lead to inaccurate testing.

[0006] 2. The device uses a fixed collision angle between the two objects during impact, without taking into account different impact angles (such as oblique impact), which can lead to inaccurate testing. Utility Model Content

[0007] This invention provides an emergency escape testing device that has the advantage of simulating different types of impact objects, thus solving the problem of simulating only one type of impact object.

[0008] To achieve the purpose of multi-form and multi-angle impact testing, this utility model provides the following technical solution: an emergency escape testing device, including a test platform, an impact block body is provided on the top of the test platform, and a first impact surface, a second impact surface and a third impact surface are respectively provided on the outer peripheral surface of the impact block body. A first groove is formed on the surface of the first impact surface, and a second groove is formed on the surface of the second impact surface. A second slider is slidably arranged in both the first and second grooves. A conical block for forming an irregular impact surface is threadedly installed on the surface of the first impact surface at the top center of the second slider. An arc-shaped panel for forming an arc-shaped impact surface is threadedly installed on the surface of the second impact surface at the top center of the second slider. A limit groove is equidistantly formed inside the third impact surface, and a counterweight block for adjusting the mass of the impact block body is provided in the limit groove.

[0009] Preferably, the test platform has four fixed limiting posts at the top corners, and a lifting plate is slidably connected to the inner side of the limiting posts. A first vertical plate is fixed to one side of the bottom of the lifting plate. Fixed blocks are symmetrically fixed to the outer side of the first vertical plate. A stepper motor is fixedly installed at the end of the fixed block. A worm gear with both ends movably penetrating the fixed block is fixed to the output end of the stepper motor. A worm wheel is meshed with the worm gear. A drive column that movably penetrates the first vertical plate is fixedly sleeved on the worm wheel. One end of the drive column is fixedly connected to the center position of the end of the impact block body.

[0010] Preferably, a second vertical plate is fixedly connected to the other side of the bottom of the lifting plate, and a connecting column is movably inserted through the center of the bottom of the second vertical plate. The end of the connecting column is fixedly connected to the center of the other end of the impact block body.

[0011] Preferably, the main body of the impact block is an equilateral triangle, and the outermost three sides of the main body of the impact block are spaced 20 centimeters apart from the bottom of the lifting plate.

[0012] Preferably, a top plate is fixedly provided on the top of the lifting plate, and a steel cable is movably passed through the top of the top plate. The top plate is connected to a release hook via the steel cable.

[0014] As a preferred technical solution of this utility model

[0015] Compared with the prior art, this utility model provides an emergency escape testing device, which has the following features:

[0016] Beneficial effects:

[0017] 1. This emergency escape testing device uses a rotatable multi-faceted impact block as its core testing component. Its different surfaces are designed in various shapes such as flat, curved, and sharp surfaces, which can accurately simulate irregular obstacles such as sharp rocks and reinforced concrete blocks that may be encountered in emergency escape scenarios. Through the transmission and positioning of worm gear and worm, the impact block can be rotated to switch between different impact surfaces, thereby simulating various sudden impact situations that may be encountered during the escape process, such as the impact of objects caused by building collapse and collisions with obstacles blocking the escape route. This effectively tests the response capability of escape equipment and improves the accuracy and reliability of test results.

[0018] 2. This device drives the third vertical plate to move laterally via a servo electric cylinder, which in turn drives the toothed plate and gears to rotate, causing the impact block to rotate at a preset angle. This changes the collision angle between the impact block and the tunnel escape house, enabling multi-angle impact tests such as vertical and oblique impacts. This effectively simulates the impact of objects from different directions in scenarios such as tunnel collapses and landslides, improving the reliability and accuracy of the test results.

[0026] 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.

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This utility model provides a technical solution: an emergency escape testing device, including a test platform 1. An impact block body 12 is disposed on the top of the test platform 1. A first impact surface 13, a second impact surface 14, and a third impact surface 15 are respectively disposed on the outer peripheral surface of the impact block body 12. A first groove 1301 is formed on the surface of the first impact surface 13, and a second groove 1401 is formed on the surface of the second impact surface 14. Second sliders 16 are slidably connected within both the first groove 1301 and the second groove 1401. The second slider 16 is composed of two blocks assembled by bolts. A conical block 17 for forming an irregular impact surface is threadedly installed on the surface of the first impact surface 13 at the top center of the second slider 16. A conical block 17 for forming an arc-shaped impact surface is threadedly installed on the surface of the second impact surface 14 at the top center of the second slider 16. The third impact surface 15 has an arc-shaped panel 18 and equidistant limit grooves 1501 inside. The limit grooves 1501 are equipped with counterweights 19 for adjusting the mass of the impact block body 12. Multiple conical blocks 17 of different sizes are movably installed on the surface of the first impact surface 13 to simulate the impact effect of rubble during tunnel collapse. Multiple arc-shaped panels 18 with different curvatures are movably installed on the surface of the second impact surface 14 to create different impact effects. By installing multiple counterweights 19 inside the third impact surface 15, the mass of the impact block body 12 is changed, so that different impact forces can be formed under the same acceleration. This can simulate diverse impact load scenarios and improve the test effect. The surface of the third impact surface 15 is horizontal, which can also form a single impact effect.

[0028] The test platform 1 has L-shaped limiting posts 2 fixedly installed at the four corners of its top. A lifting plate 3 is slidably connected to the inner side of the limiting posts 2. A first vertical plate 4 is fixedly installed on one side of the bottom of the lifting plate 3. Fixing blocks 7 with circular holes on their sides are symmetrically fixedly installed on the outer side of the first vertical plate 4. A stepper motor 8 is fixedly installed at one end of one of the fixing blocks 7. A worm gear 9 is fixedly connected to the output end of the stepper motor 8. Both ends of the worm gear 9 pass through the circular holes on the side of the fixing block 7. A worm wheel 10 is meshed with the worm gear 9. A drive column 11 is fixedly sleeved on the worm wheel 10. The drive column 11 passes through the circular holes on the side of the first vertical plate 4. One end of the drive column 11 is fixedly connected to the center of the end of the impact block body 12. The other side of the bottom of the lifting plate 3 is fixedly connected to... There is a second vertical plate 5, and a circular hole is opened at the center of the bottom of the second vertical plate 5. A connecting column 6 moves through the circular hole. The end of the connecting column 6 is fixedly connected to the center of the other end of the impact block body 12. The impact block body 12 is an equilateral triangle. The outermost three sides of the impact block body 12 are spaced 20 cm apart from the bottom of the lifting plate 3. The stepper motor 8 drives the worm 9 and worm wheel 10 to rotate, which in turn drives the drive column 11 to rotate, which in turn drives the impact block body 12 to rotate. This allows the position of the first impact surface 13, the second impact surface 14 and the third impact surface 15 to be adjusted. Under the action of the worm 9 and worm wheel 10, a strong self-locking effect can be formed, which can lock the impact angle of the impact block body 12.

[0029] A top plate 20 is fixedly installed at the center of the top of the lifting plate 3 by bolts. A lifting ring is fixedly installed at the top of the top plate 20. A steel cable 21 is movably inserted through the top of the top plate 20 within the lifting ring. A release hook 22 is connected to the top plate 20 via the steel cable 21. A slide rail 101 is provided on the top of the test platform 1. A first slider 102 is slidably connected to the top of the slide rail 101. A support block 103 with its bottom surface sliding with the top of the test platform 1 is fixedly connected to the top of the first slider 102. A pulley 104 is symmetrically fixedly installed at the bottom of the support block 103 away from the first slider 102. The height of the pulley 104 is the same as the thickness of the test platform 1. A tunnel escape house 23 is placed on the top of the support block 103.

[0030] The working principle and usage process of this utility model are as follows: First, the impact block body 12 is hoisted to a fixed height using hoisting equipment. Then, when a strength test is required on the tunnel escape house 23, the support block 103 is pushed. Under the action of the slider 102 and the pulley 104, the support block 103 is moved to one side of the test platform 1 (e.g., Figure 2(As shown), then the tunnel escape house 23 is placed on top of the support block 103, and then the support block 103 is pushed so that the tunnel escape house 23 is located at the bottom of the impact block body 12. During the test, by opening the release device 22, the release device 22 is separated from the steel cable 21. Under the action of gravity, the top plate 20, the lifting plate 3 and the impact block body 12 will move vertically downward under the limiting action of the limiting post 2, so that the impact block body 12 will hit the outer surface of the tunnel escape house 23. At this time, an external camera can be placed on one side of the test platform 1 to record the impact scene and the degree of damage after the impact.

[0031] When different impact surfaces need to be adjusted, the impact block 11 is first hoisted to the designated height again. The stepper motor 8 drives the worm gear 9 and worm wheel 10 to rotate, which in turn drives the drive column 11 to rotate, thereby rotating the impact block body 12. This allows the positions of the first impact surface 13, the second impact surface 14, and the third impact surface 15 to be adjusted. After selecting an impact surface, the release device 22 is opened again, allowing the impact block 11 to impact the tunnel escape house 23. By impacting the tunnel escape house 23 with the first impact surface 13, the second impact surface 14, and the third impact surface 15, the impact effects of different impact objects are simulated, thereby improving the accuracy of the test.

[0032] It should be noted that the conical block 17 and the arc-shaped panel 18 in this embodiment are only used to form different impact surfaces, which include but are not limited to the shapes shown in the figures. Other shapes can be selected according to the actual needs of the device.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
