Description

Technical Field

[0001] This utility model relates to evacuation and escape equipment for rail transit personnel, specifically, to an emergency evacuation ramp that is easy to fix. Background Technology

[0002] In the operation of rail transit, the rapid and safe evacuation of passengers during emergencies is a crucial aspect of ensuring passenger safety. Emergency evacuation ramps, as an important evacuation and escape device, play a vital role in creating temporary passages between trains and platforms, and between trains themselves, providing escape routes for passengers. Currently, there are many types of emergency evacuation ramps available on the market, which to some extent meet the basic needs of rail transit evacuation and escape. These ramps are typically made of materials with sufficient strength and stability to withstand the weight and movement of passengers, ensuring that they will not break or collapse during evacuation, and guaranteeing that passengers can smoothly evacuate to a safe area.

[0003] In emergencies, time is of the essence. However, existing evacuation ramps are often difficult to deploy quickly, requiring considerable time for installation and debugging. This undoubtedly increases the time cost of evacuation and reduces evacuation efficiency. Furthermore, some evacuation ramps are large and heavy, making them cumbersome to move and placing a significant burden on workers. This also hinders the rapid delivery of the ramps to designated locations for use in emergencies.

[0004] Therefore, we have made improvements to this by proposing an emergency evacuation ramp that is easy to fix. Utility Model Content

[0005] In order to achieve the above-mentioned objectives, this utility model provides an emergency evacuation ramp that is easy to fix, so as to improve the above-mentioned problems.

[0006] The application is as follows:

[0007] include:

[0008] The retractable ladder, platform and steps are connected in sequence, and the horizontal plane gradually decreases from the step to the retractable ladder.

[0009] The telescopic ladder includes:

[0010] pedal;

[0011] The baffle is symmetrically rotated and installed on the steps of the telescopic ladder. When rotated to be perpendicular to the steps, it restricts the objects on the steps from shifting to both sides.

[0012] A groove is formed on the pedal for the baffle to fit into the pedal;

[0013] The platform includes:

[0014] Hydraulic telescopic rods are installed on the platform and steps, extending towards the lower horizontal plane;

[0015] The support plate is slidably mounted on the hydraulic telescopic rod and forms a support surface with the low horizontal plane. It has a slot for sliding and a mounting slot for threaded connection.

[0016] A locking mechanism is provided on the hydraulic telescopic rod;

[0017] The rollers, located at the end of the hydraulic telescopic rod, are braked by the compression of the support plate's slot.

[0018] Preferred options also include:

[0019] The evacuation platform, located above the track, is formed by the surface on which the vehicles are driven.

[0020] Preferred options also include:

[0021] The guardrail is installed on the platform and steps and is collinear with the baffle perpendicularly.

[0022] Preferably, the telescopic ladder has at least one pair of foldable diagonal braces on its side, one end of which is hinged to the side frame of the telescopic ladder.

[0023] Preferably, the groove of the support plate is smaller than the diameter of the roller.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] In the scheme of this application:

[0026] To address the problems in existing technologies, this application achieves seamless lateral protection throughout the evacuation route by using a rotating baffle and a continuous guardrail perpendicular to it, eliminating the risk of falls. A composite support structure consisting of a hydraulic telescopic rod and the evacuation platform enables adaptive adjustment of the platform height and rigid anti-settlement measures. Friction braking triggered by the sliding and pressing rollers of the support plate, along with rigid locking, provides dual anti-displacement fixation of the support end on the ground. Ultimately, this ensures rapid and stable evacuation of personnel from the stairs to the telescopic ladder, with no risk of slippage, collapse, or displacement throughout the entire process.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0034] For an example, please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4 An emergency evacuation ramp that is easy to fix includes:

[0035] The telescopic ladder 1, platform 2 and steps 3 are connected in sequence, and the horizontal plane gradually decreases from the step 3 to the telescopic ladder 1.

[0036] Telescopic ladder 1 includes:

[0037] pedal;

[0038] The baffle 11 is symmetrically rotated and installed on the step of the telescopic ladder 1. When rotated to be perpendicular to the step, it restricts the objects on the step from shifting to both sides.

[0039] A groove 12 is formed on the pedal so that the baffle 11 can be fitted onto the pedal.

[0040] Platform 2 includes:

[0041] Hydraulic telescopic rods 22 are installed on platform 2 and steps 3, extending towards the lower horizontal plane;

[0042] The support plate 23 is slidably mounted on the hydraulic telescopic rod 22 and forms a support surface with the low horizontal plane. It has a slot for sliding and a mounting slot for threaded connection.

[0043] Lock 24 is mounted on the hydraulic telescopic rod 22;

[0044] Roller 25 is located at the end of hydraulic telescopic rod 22 and is braked by the squeezing of the slot in support plate 23;

[0045] When the baffle 11 rotates from the groove 12 to a position perpendicular to the pedal, the symmetrically erected baffles 11 immediately form a physical barrier on both sides of the pedal. In this state, when evacuees step on the pedal, their feet or personal belongings are strictly confined within the passage between the baffles 11, effectively preventing lateral slippage accidents caused by panic or slope. When the baffle 11 re-engages into the groove 12, the pedal returns to a flat position, avoiding the risk of tripping during storage or transportation.

[0046] When the hydraulic telescopic rod 22 extends towards the lower level of the ground, the support plate 23 slides along the hydraulic rod until it contacts the ground to form a support surface. At this time, the hydraulic system can dynamically adjust the support height, adaptively compensate for the unevenness of the ground, and ensure that the platform 2 always remains horizontal and stable.

[0047] When the baffle 11 is vertically erected and the guardrail 21 is extended on both sides of the platform 2 and the steps 3, the vertical extension surface of the guardrail 21 is precisely collinearly aligned with the baffle 11. This design allows lateral protection to seamlessly extend from the steps of the telescopic ladder 1 to the end of the steps 3, forming a continuous barrier without any breaks. When personnel pass through, their bodies are always within the protected area, completely eliminating the risk of falls at the junctions of the steps and the platform 2, and the platform 2 and the steps 3.

[0048] Also includes:

[0049] Evacuation platform 4 is located above the track and is formed by the load-bearing surface of the moving vehicles;

[0050] Because there is a height difference between the moving vehicles and the track, it is necessary to balance this difference by using a ramp to overcome it.

[0051] Also includes:

[0052] Guardrail 21 is installed on platform 2 and steps 3, and is perpendicular to and collinear with baffle 11.

[0053] The guardrail 21 is precisely collinearly aligned with the erected baffle 11, eliminating protective gaps and providing uninterrupted lateral protection for evacuees from the telescopic ladder 1 to the platform 2 and then to the steps 3, greatly reducing the risk of falling.

[0054] The side of the telescopic ladder 1 is provided with at least one pair of foldable diagonal braces, one end of which is hinged to the side frame of the telescopic ladder 1.

[0055] The addition of multiple triangular support components enhances the stability of the telescopic ladder 1 and limits its downward range. At the same time, the end of the telescopic ladder 1 that contacts the ground is equipped with rollers controlled by a locking device to counteract the deformation of the telescopic ladder during stepping.

[0056] The slot of the support plate 23 is smaller than the diameter of the roller 25. Using the slot, when the support plate 23 is fixed to the ground through the mounting slot, the roller 25 is engaged, causing the roller 25 to lose its rotation ability and stabilizing the bottom support effect. When the locking buckle 24 is set to a position away from the roller 25, the roller 25 resumes rotation, allowing the entire roller 25 to drive the platform 2 or the steps 3 to move, so that the entire device can be quickly unfolded and stored, and is easy to move.

[0057] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
