[0032] Below, the embodiments of the present invention are described in detail with reference to the accompanying drawings.

[0033] Example

[0034] Please refer to Figures 1 to 3 ,This embodiment provides a double-deck unpowered aerial vehicle for use in a barrier room, comprising a vehicle body and guardrails;

[0035] The vehicle body is provided with a bottom platform 1 and a standing platform 2, which are connected by a frame 3. The frame 3 includes four vertical poles, the ends of which are welded to the four corners of the bottom platform 1 and the standing platform 2 to support the standing platform 2. Cross bars are welded between adjacent vertical poles, and all cross bars are located on the same plane to enhance the strength of the frame 3.

[0036] The bottom platform 1 and the standing platform 2 are both flat plates. The upper surface of the standing platform 2 is provided with anti-slip grooves. Specifically, the standing platform 2 uses a 3mm thick patterned steel plate. The pattern on its surface can increase friction and prevent the operator from slipping when stepping on it.

[0037] The guardrails include two side guardrails 4, a front guardrail 5, and a rear guardrail 6. The bottom edges of the two side guardrails 4, the bottom edges of the front guardrail 5, and the bottom edges of the rear guardrail 6 are all rotatably connected to the sides of the standing platform 2; the two side guardrails 4 are detachably connected to the front guardrail 5 and the rear guardrail 6; the rear guardrail 6 is provided with multiple cross bars, and when the rear guardrail 6 is folded down, it can serve as a ladder for the operator to climb to the standing platform 2;

[0038] The two side guardrails 4, the front guardrail 5 and the rear guardrail 6 are all welded with stainless steel square tubes, and the overall structure is a square frame; the bottom edges of the two side guardrails 4, the bottom edges of the front guardrail 5, and the bottom edges of the rear guardrail 6 are all rotatably connected to the sides of the standing platform 6 through rotating shafts; the aerial platform is usually stored in the barrier room. When the aerial platform is not in use, the guardrails connected to each other can be disassembled and flipped downwards, which can reduce the space in the height direction and improve the space utilization rate of the barrier room.

[0039] The two side guardrails 4, the front guardrail 5 and the rear guardrail 6 are installed with pins that can be disassembled and connected to each other. When they need to be assembled into an integral guardrail, they are connected to each other through the pins. The connection through the pins is convenient and fast.

[0040] When the aerial platform needs to be used, the two side guardrails 4 and the front guardrail 5 are first flipped upward and connected, and the operator climbs onto the standing platform 2 through the folded rear guardrail 6; in order to better protect the safety of the operator, the rear guardrail 6 is flipped upward and connected to the two side guardrails 4, and the operator is surrounded by the guardrails, which improves the safety of the operation.

[0041] In another embodiment, the two upright poles of each side guardrail 4 are telescopic poles, and the telescopic poles adopt existing products with spring locks. The two side guardrails can be telescoped to adjust the height, which can better adapt to the use of people of different heights; the two side guardrails 4 are designed to be liftable, and the spring locks built into the upright poles can be pressed down by fingers to adjust the height of the side guardrails 4 up and down. The pins can be installed on the two outer sleeves of the telescopic poles respectively, and will not change position as the side guardrails 4 are raised. No matter what height the side guardrails 4 are at, they can be locked with the front guardrail 5 and the rear guardrail 6 to ensure that different heights can be connected to each other to protect the safety of the operator.

[0042] The storage rack 8 is mounted on the guardrails. Specifically, the racks 8 are located on top of both the front and rear guardrails 5, 6. Both racks 8 extend outward and are vertically connected to the front and rear guardrails 5, 6, respectively. When the front and rear guardrails 5, 6 are tilted upward and assembled, the racks 8 assume a horizontal position. The racks 8 are a flat, welded structure made of multiple steel pipes, facilitating the temporary storage of items during operation. Diagonal braces are welded between the racks 8 and the front or rear guardrails 5, 6, to enhance the strength of the connection.

[0043] The body, guardrail and placement frame 8 of the aerial platform are all made of stainless steel, which is rust-proof and anti-corrosion. It can enter the high-pressure room for disinfection, and can be wiped with disinfectant in all directions without dead angles for daily disinfection, which can effectively reduce biosafety risks. Stainless steel can also avoid problems such as rust and corrosion, reduce the risk of environmental pollution, and increase service life.

[0044] In this embodiment, the width of the bottom platform 1 is equal to that of the standing platform 2, and the length of the bottom platform 1 is greater than that of the standing platform. The front ends of the bottom platform 1 and the standing platform 2 are aligned, and the rear guardrail 6 is tilted and arranged between the bottom platform and the standing platform after being folded down. As a ladder, it is in an inclined state, which facilitates climbing by the operator.

[0045] In this embodiment, four wheels 9 are provided at the four corners of the bottom of the bottom platform 1, of which the front two are fixed wheels and the rear two are universal wheels. The wheels are a combination of universal wheels and fixed wheels to reduce the direction deviation during driving and avoid hitting the cage.

[0046] All four wheels are equipped with brake mechanisms. The directional wheel is connected to a handbrake lever 7. One end of the handbrake lever 7 is connected to the brake pedal of the brake structure of the directional wheel. When the operator pulls the handbrake lever 7 on the vehicle, the handbrake lever 7 drives the brake of the directional wheel to lock the directional wheel. The operator stands on the operating platform and can brake at any time; the brake can be braked at any time to prevent the vehicle from slipping. All wheels and brake mechanisms adopt existing technology products.

[0047] In this embodiment, an anti-tilt column 10 is provided on the bottom surface of the bottom platform 1 next to each wheel 9, and the anti-tilt column 10 can prevent the vehicle body from tilting.

[0048] In specific applications, the bottom surface of the anti-tilt column 10 is slightly higher than the lowest point of the wheel 9. When one wheel 9 is damaged, the anti-tilt column 10 can contact the ground to ensure that the vehicle does not roll over.

[0049] When the double-layer, non-powered climbing platform for a barrier room of this embodiment is in use, the two side guardrails 4 and the front guardrail 5 are connected. After the operator climbs to the standing platform 2 by lowering the rear guardrail 6, the rear guardrail 6 can be flipped upward to connect with the two side guardrails 4. The operator can temporarily place items on the storage rack 8 for easy access. When the climbing platform is not in use, the two side guardrails 4 and the front guardrail 5 can be disassembled and flipped downward to be stored in the barrier room, reducing the space occupied by the barrier room. The double-layer, non-powered climbing platform for a barrier room of this embodiment is manually propelled and does not require additional power. Compared with electric lifting vehicles, it has a simpler structure, lower manufacturing costs, and is easier to disinfect, making it more suitable for use in barrier rooms.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
