Description

Technical Field

[0001] The utility model relates to the technical field of fire trucks, in particular to a working bucket of a fire truck. Background Art

[0002] Fire trucks are special vehicles used by fire departments to extinguish fires and conduct rescue operations. They are usually specially designed and manufactured, equipped with fire-fighting equipment, rescue tools and protective equipment, and can reach the fire scene quickly and safely to effectively perform rescue tasks. The ladder and work bucket of a fire truck are common rescue tools. The work bucket is set at the top of the ladder. Firefighters enter the work bucket and use the ladder to lift the work bucket and firefighters to the required height for rescue operations.

[0003] At the fire rescue scene, the fire truck's working bucket is often needed to rescue the trapped people at the fire scene. The working bucket rises to the balcony or window of the fire floor, and the trapped people climb over the balcony or window by themselves or with the assistance of firefighters, and are transferred to the working bucket for rescue. In the prior art, in an emergency, the trapped people often do not have a ladder to help climb over the balcony guardrail or window sill, and need to rely on their own physical strength and the assistance of firefighters, which is particularly physically demanding for both the trapped people and the firefighters, especially in emergency situations with large fires, high temperatures, and thick smoke, which brings inconvenience to rescue. Therefore, our company has designed and proposed a fire truck working bucket that is convenient for rescue work. Utility Model Content

[0007] Preferably, the fixing seat comprises a fixing shaft and an anti-slip disk, and the diameter of the anti-slip disk is greater than the width of the vertical groove.

[0008] Preferably, the difference between the length of the vertical groove and the diameter of the fixed shaft is not less than the height of the positioning hook.

[0009] Preferably, there are two positioning hooks, and they are symmetrically arranged on the left and right corresponding to the positioning cross bars.

[0010] Preferably, both ends of the movable connecting frame are movably hinged to the top crossbar and the top of the ladder respectively.

[0011] Preferably, the length of the movable connecting frame is 0.2~0.4m.

[0012] Preferably, the height of the ladder is 1-1.5 m.

[0013] Preferably, a high temperature resistant and non-slip rubber foot is fixedly connected to the bottom of the ladder.

[0014] Preferably, there are no less than two storage hooks.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] (1) The movable frame of the utility model is limited by a fixed seat, and the position of the movable frame is fixed under the action of a positioning hook. The ladder hinged by the movable connecting frame can be flipped upward to cross the balcony or window sill and extend into the building. The trapped people and firefighters inside can climb and walk by the ladder, which reduces physical exertion, protects the trapped people and firefighters, brings convenience to rescue and walking, and facilitates the rescue work.

[0017] (2) By setting a fixed seat, a movable frame, a movable connecting frame, a ladder and a storage hook, when the ladder is not needed, the movable frame is pulled upward to separate the positioning crossbar from the positioning hook, the movable frame, the movable connecting frame and the ladder are rotated around the fixed seat, the ladder and the movable connecting frame are moved closer to the movable frame to complete the folding, and the movable frame and the ladder are hooked by the storage hook to complete the storage, which occupies a small space and is easy to use.
