Description

Technical Field

[0001] The utility model relates to a fire-fighting material transport vehicle. Background Art

[0002] In the process of firefighting and rescue, time is life, especially the equipment and transportation of various firefighting materials and equipment. However, due to the complex terrain and environment of the rescue area, fire trucks cannot pass in many cases, so firefighters are required to use wheelbarrows or even manually carry the rescue materials to the destination. The transportation efficiency is low, and the wheelbarrows used are generally not easy to carry on the fire truck, resulting in many cases of temporary searches on the scene, resulting in many cases still relying on manual transportation, which delays the rescue time. Especially during the rescue, a lot of firefighters' energy is consumed in the transportation of materials, delaying normal rescue operations.

[0003] CN210912525U discloses a foldable fire-fighting equipment trolley, which is formed by a foldable frame and can save storage space, but the trolley box after unfolding is a rectangular space.

[0004] CN218431317U discloses a folding cart, in which a plurality of circular placement positions are arranged on the bottom frame of the foldable body, a fixed net is arranged on the top of the body, the fixed net is connected to the top of the side frame, and a fixed position is arranged corresponding to each circular placement position for placing gas cylinders and other materials, but the function is too single.

[0005] CN216684650U discloses a foldable multifunctional fire-fighting equipment transport device, wherein a fixing frame on a trolley is folded onto a baffle plate on the fixing frame to form a foldable transport vehicle.

[0008] However, the above transport vehicles all have an obvious defect: in order to facilitate folding and reducing the volume, the wheels are designed to be small, resulting in a weak obstacle-crossing capability. In fire rescue, the complexity of the environment is an issue that cannot be circumvented, such as rugged roads, sometimes there may be no roads at all, sometimes it is necessary to climb stairs or climb over obstacles. In these cases, transport vehicles with smaller wheels are difficult to complete.

The vehicle can not only be folded and placed in a small space, but also has a strong obstacle-crossing capability during use. However, in practice, especially when a large slope is required, such as going up and down stairs, the materials on the transport vehicle will have a problem of excessive inclination, and the materials will easily slip if not carefully paid attention to.

[0010] Therefore, a fire-fighting material transport vehicle which can maintain a relative balance of materials on the transport vehicle to a certain extent even when the slope is large has come into being. Summary of the invention
