AI Technical Summary

Technical Problem

The existing folding telescopic boom structure of fire trucks increases the overall vehicle load and design complexity, leading to higher production costs and limited fire extinguishing efficiency.

Method used

Design a single folding telescopic boom structure, including a main telescopic pipeline and a secondary telescopic pipeline, both of which are installed on the folding telescopic boom and are driven to extend and retract by a drive source. The main telescopic pipeline is connected to the water channel under the vehicle, and the secondary telescopic pipeline is supplied with water through an external water supply port. First and second water cannons are respectively installed for fire extinguishing operations.

Benefits of technology

The fire extinguishing effect of dual water cannons is equivalent to the fire extinguishing capacity of two fire trucks, while reducing the overall vehicle weight, design difficulty, and production cost.

Abstract

The application provides a single folding telescopic arm structure and a fire truck, and relates to the technical field of firefighting. The single folding telescopic arm structure comprises a folding telescopic arm, a main telescopic pipeline and a secondary telescopic pipeline. The main telescopic pipeline is arranged on the folding telescopic arm. One end of the main telescopic pipeline is in communication with a lower vehicle water pipeline, and the other end is provided with a first water cannon. The secondary telescopic pipeline is arranged on the folding telescopic arm. The folding telescopic arm can drive the main telescopic pipeline and the secondary telescopic pipeline to be telescopic. One end of the secondary telescopic pipeline is provided with an external water supply port, and the other end is provided with a second water cannon. The single folding telescopic arm double water cannon fire extinguishing mode is adopted, which has the effect that one fire truck is equivalent to two fire trucks to jointly extinguish fire at the same position. The fire extinguishing mode remains consistent, the fire extinguishing flow of the double water cannons remains unchanged, the overall weight is reduced, the design difficulty is reduced, and the production and manufacturing cost is saved.
