Description

Technical Field

[0001] The utility model relates to the technical field of special equipment devices, and in particular to an emergency safety device for special equipment. Background Art

[0002] With the continuous progress of society and the rapid advancement of urbanization, modern society has put forward higher requirements for emergency rescue capabilities. As an important special equipment, emergency safety devices for special equipment have played a pivotal role in tasks such as anti-terrorism conflicts and emergency rescue. It is mainly used to assist commandos to quickly climb buildings, climb over walls or quickly approach cabin doors. At the same time, it is often used as an effective tool for evacuating people in emergency situations such as fires.

[0003] However, with the acceleration of urbanization and the relative stability of the social environment, the demand for anti-terrorism conflicts has gradually decreased, while the demand for emergency rescue has increased. Especially in emergencies such as fires, the rapid and effective evacuation of the masses has become the primary task of rescue work. Although the existing design of emergency safety devices for special equipment can meet the needs of commandos for rapid action, it seems to be powerless when rescuing the masses. Considering that the rescued masses may include the elderly and children, their mobility is relatively weak and they cannot quickly cooperate with the use of emergency safety devices for special equipment, which to a certain extent affects the speed and efficiency of the rescue. The emergency safety devices for special equipment currently on the market have not been optimized for this specific scenario, which results in slow rescue speed and long rescue time in the actual rescue process, which cannot meet the high requirements of speed and efficiency for modern emergency rescue.

[0004] Although Chinese patent CN219101197U discloses a new climbing assault vehicle, which has advantages in assisting commandos to climb quickly, it still has obvious shortcomings in its application in mass rescue. Therefore, there is an urgent need for a special equipment emergency safety device design that can take into account both the commandos' actions and the mass rescue needs, so as to improve the overall rescue efficiency, shorten the rescue time, and maximize the protection of people's lives.

Such a lifting mechanism design makes the lifting of the lifting slope more stable and reliable, and the operation is simple and convenient.

[0034] Furthermore, a first support seat 63 is provided at the bottom of the lifting slope, and an upper connecting rod is rotatably connected to the first support seat.

[0035] Furthermore, a second support seat 64 is provided in the middle of the upper connecting rod, and a telescopic rod of a central electric cylinder is rotatably connected to the second support seat.

[0036] In at least one embodiment, a lower electric cylinder is fixedly connected to the bottom of the lifting slope, and a telescopic rod of the lower electric cylinder is connected to the bottom of the extension slope. Through the telescopic movement of the lower electric cylinder, the extension length of the extension slope can be flexibly adjusted to meet the rescue needs of more scenarios.

[0037] In at least one embodiment, Figure 3 As shown, the angle adjustment mechanism includes a third support seat 81, a fourth support seat 83 and an adjustment electric cylinder 82. The third support seat is provided at the bottom of the extension slope 7, and the fourth support seat is provided at the bottom of the lap plate.

Such a design allows the climbing ladder to be moved left and right and fixed relative to the air cushion, so that the position of the air cushion can be adjusted according to actual conditions.

[0039] In at least one embodiment, Figures 6 to 9 As shown, the climbing ladder includes two parallel left plates 31 and right plates 32, a pedal 33 is rotatably connected between the left plate and the right plate, and a linkage mechanism is provided on the outer sides of the left plate and the right plate, and the linkage mechanism can drive the pedal to rotate so that the multiple pedals form a smooth plane, which is convenient for people to slide down. Such a climbing ladder design can be used for climbing and can be quickly converted into a slide in an emergency, which improves the speed and efficiency of escape.

[0040] Specifically, taking the left plate as an example, the linkage mechanism includes a plurality of first rotating shafts 34, on which pedals are rotatably connected, and the first rotating shaft passes through the left plate and is rotatably connected to a linkage plate 35, and the end of the linkage plate is rotatably connected to a second rotating shaft 36, and a plurality of the second rotating shafts are rotatably connected to a long connecting plate 37.

Check whether all mechanical parts such as electric cylinders, connecting rods, rotating shafts, etc. are working properly without damage or jamming. Ensure that the air cushion is inflated and in good condition, and the slider and slide are adjusted appropriately so that they can be moved and fixed as needed. Use the lifting mechanism (including the lower connecting rod, the upper connecting rod and the central electric cylinder) to adjust the height of the lifting slope. By controlling the extension and contraction of the central electric cylinder, the lifting slope can be lifted and lowered smoothly. During the lifting process, pay attention to the surrounding environment to ensure that there are no obstacles hindering the movement of the lifting slope. Use the angle adjustment mechanism (including the third support seat, the adjustment electric cylinder and the fourth support seat) to adjust the angle between the extension slope and the lap plate. By controlling the extension and contraction of the adjustment electric cylinder, the angle can be flexibly adjusted. According to actual needs, the extension slope can be adjusted to a suitable inclination angle so that it can be overlapped with platforms at different heights.

[0045] Under normal circumstances, the steps of the climbing ladder are in a step state, and people can quickly climb to the top of the truss frame along the steps. In emergency situations, such as fire rescue, the steps can be rotated and formed into a smooth plane by adjusting the position of the fixing bolts on the long connecting plate. In this way, people can quickly slide down the climbing ladder and achieve rapid evacuation.

[0046] The air cushion can be placed at the bottom of the climbing ladder for added safety. Before use, make sure the air cushion is fully inflated and placed in the proper position. As needed, the position of the air cushion can be adjusted using the slider and the slide, and fixed in the desired position by the left or right fastening bolts.

[0047] Regularly check and replace worn parts to ensure the normal operation and safety of the equipment. Keep the equipment clean and dry to prevent rust and corrosion. Regularly lubricate key components such as electric cylinders and shafts to reduce wear and extend service life.
