Fire truck telescopic arm structure

Abstract

The invention discloses a fire fighting truck telescopic boom structure. The fire fighting truck telescopic boom structure comprises a truck body. The fire fighting truck telescopic boom structure is characterized in that two telescopic booms arranged symmetrically are hinged to the truck body, and the two telescopic booms are sleeved with double sleeves in a sliding mode; the double sleeves are hinged to the operating end of a telescopic boom cylinder, and the bottom end of a cylinder barrel part of the telescopic boom cylinder is hinged to the truck body; an inhaul cable arm matched with the telescopic booms is arranged, and sleeved with a sleeve in a sliding mode; the sleeve is hinged to the operating end of an inhaul cable arm cylinder, and the bottom end of a cylinder barrel part of the inhaul cable arm cylinder is also hinged to the truck body; a plurality of inhaul cables are connected between the telescopic booms and the inhaul cable arm; the telescopic function of the telescopic booms and the inhaul cable arm is achieved through the same telescopic structure. The fire fighting truck telescopic boom structure is simple, ingenious in design, and capable of greatly increasing the stretching out upper limit of a scaling ladder and achieving rapid extension.

Description

technical field [0001] The invention relates to a supporting structure of a fire truck, in particular to a telescopic arm structure of a fire truck. Background technique [0002] When a fire occurs in a high-rise building, it is often necessary to use a fire truck with a ladder to extinguish the fire and rescue the trapped. The traditional ladder has a very limited lifting height due to its own structural limitations.

Problems solved by technology

[0002] When a fire occurs in a high-rise building, it is often necessary to use a fire truck with a ladder to extinguish the fire and rescue the trapped. The traditional ladder has a very limited lifting height due to its own structural limitations. Once the fire point is at its limit In addition, the traditional aerial ladder is operated step by step during the expansion and contraction process, and the overall expansion and contraction time is relatively long, which seriously affects the rescue efficiency and makes it difficult to carry out rapid rescue; and the carrying capacity of the traditional aerial ladder is very high. limited, which also restricts the efficiency of rescue; at the same time, the traditional aerial ladder can only realize vertical lifting, and cannot realize horizontal transportation of the hanging basket and fire extinguishing device on it, which requires fire trucks to be near the fire building Lifting the gondola, but due to the environmental constraints of the fire scene, sometimes the fire truck cannot approach the fire building, which leads to the problem that the gondola at the top of the ladder cannot move to the fire floor

At the same time, when carrying out fire extinguishing operations for some explosive combustibles, if the rescuers are too close to the fire point, once the combustibles explode, it may cause heavy personal casualties to the rescuers. If the fire can be implemented remotely, the above problems can be avoided , but the traditional ladder structure can only lift in the longitudinal direction, and cannot support a long cantilever structure to implement long-distance fire fighting, which has certain limitations
