Description

Technical Field

[0001] This utility model belongs to the field of fire protection equipment technology, and more specifically, relates to a fire hose carrying trolley. Background Technology

[0002] Firefighting equipment refers to equipment used for fire extinguishing, fire prevention, and handling fire accidents; it includes specialized firefighting equipment. The most common firefighting equipment includes fire extinguishers and fire hoses. A fire hose is a device that sprays high-pressure water, primarily used for extinguishing large fires and long-distance firefighting. A typical firefighting line includes fire hoses and fire hoses; when using indoor fire hydrants, an adapter is required. In actual firefighting situations, these components require two people to retrieve them from different equipment boxes, which is time-consuming and laborious, hindering rapid initial deployment. Furthermore, there is a risk of delaying firefighting due to confusion at the scene or the mistakenly taking or forgetting a component. Therefore, designing a portable device that can simultaneously carry fire hoses and allow for rapid transport is of significant practical importance for firefighting and rescue operations.

[0003] A search revealed that patent CN115723825A discloses a fire-fighting equipment transport vehicle. This application includes a frame, seat frame, support frame, guardrail, electric telescopic rod, lifting frame, chain, and wheels. The frame is sequentially equipped with connecting plates one, two, and three. Connecting plate one has a controller. The seat frame is respectively engaged with connecting plates two and three. The support frame is mounted on the frame. The guardrail is hinged to the frame and has pins. The guardrail is fixed to the support frame via the pins. The electric telescopic rod is mounted on connecting plate one, with a connecting rod at its free end. The connecting rod has a gear. The frame has a groove, and the lifting frame slides within the groove. One end of the chain is mounted on connecting plate one, and the other end is mounted on the lifting frame. The chain is sleeved on the gear. The wheels are mounted on the frame.

[0004] For example, patent CN210912525U discloses a foldable fire equipment trolley. In this application, the entire device is foldable, saving storage space. It can be folded into a straight line to pass through narrow roads, and can be pushed or pulled on flat roads with all four wheels on the ground. It can bear a weight of up to 100kg, has a high load-bearing capacity but a light body, is highly adaptable, flexible and convenient. The body design can be used to attach and fix items, and can carry various equipment. At the same time, the fire folding trolley can also transport multiple rolls of fire hose at once, solving the problem of firefighters having to repeatedly return to the fire truck to retrieve hoses after laying a section, thus saving valuable rescue time.

[0005] The aforementioned applications all involve technical improvements to fire equipment transport devices, but the industry still needs more diverse and sophisticated designs to address the problem that carrying traditional fire hoses is time-consuming and laborious, hindering rapid firefighting operations.
