Description

Technical Field

[0001] The invention belongs to the technical field of fire trucks, and in particular relates to a fire truck for automatically laying fire hoses. Background Art

[0002] A fire truck is a special vehicle designed to respond to fires and other emergencies. It is equipped with a variety of firefighting equipment and tools, among which the fire hose is one of the key firefighting tools. The fire hose connects the water source and the fire source to deliver a large amount of water to the fire scene to quickly control the fire and extinguish the fire.

[0003] However, in the current fire truck technology, there are still some significant deficiencies in the automatic laying device of fire hose. Most traditional fire trucks rely on manual laying of hoses, which is not only time-consuming and laborious, but may also delay the firefighting in an emergency. Although some fire trucks have begun to be equipped with automatic laying devices in recent years, these devices often lack sufficient flexibility and are difficult to adapt to complex and changing terrain and fire source locations.

[0004] Especially in complex environments such as mountains, hills or narrow streets, existing automatic laying devices are often unable to accurately lay water hoses to designated locations. In addition, existing devices lack effective adjustment methods for fire sources at different heights, which greatly reduces the water spraying effect. Summary of the invention
