Embodiment 1

[0034] Such as figure 1 and figure 2 A climbing platform fire truck with a rescue ladder mounted on top of a transition platform is shown, including a chassis 1, a sub-frame 2, a turntable 3, a mixing boom 4, a rescue ladder 5, a working platform 7, and a transition platform 6;

[0035] Described mixing jib frame 4 is made up of lower arm 8, upper arm 14, curved arm 16, and lower arm 8 has left lower arm 9 and right lower arm 10 two parts, and upper arm 14 is positioned between left lower arm 9 and right lower arm 10, upper arm 14 Hinged to the middle part of the front end of the lower arm 8, the lower arm 8 has a small unbalanced load, and the left lower arm 9 and the right lower arm 10 share the load, which improves the force condition of the lower 8 arms. When the upper arm 14 is closed, it falls on the left lower arm 9 and the right The lower arm 10 has reduced the height of the car; the free end of the upper arm 14 is hinged with a curved arm 16, the working platform 7 ...

Embodiment 2

[0041] Such as image 3 and Figure 4 Another type of climbing platform fire truck with a rescue ladder on top of a transition platform is shown, including a chassis 1, a sub-frame 2, a turntable 3, a hybrid arm frame 4, a rescue ladder 5, a working platform 7, and a transition platform 6,

[0042] Hybrid jib 4 is made up of lower arm 8, upper arm 14, curved arm 16; 21; when the upper arm 14 adopts a two-section boom telescopic structure, it includes an upper arm basic arm 26, an upper two-section arm 27, and an upper three-section arm 28; When receiving the car, the three-section arm of the upper arm 14 shrinks and falls in the middle of the lower arm 8, reducing the height of the vehicle; 7. Set the rescue passage opening.

[0043] The transition platform 6 of this embodiment is hinged on the front ends of the lower left telescopic arm 19 and the lower right telescopic arm 21, has an automatic leveling function, and keeps level with the chassis 1; , the right lower teles...

Abstract

The invention discloses a rescue ladder stand overhead climbing platform fire truck with a transition platform, and belongs to the technical field of fire trucks. A mixed arm support (4) structure isadopted, the fire truck is provided with the transition platform (6), in particular, the mixed arm support (4) and a corresponding rescue ladder stand (5) adopt a multi-section telescopic structure, so that the fire truck has the following remarkable technical effects and social benefits that an automatic leveling function is achieved, the transition platform can be kept horizontal with the chassis, the height of the arm support after being collected is low, the stress condition is more stable, the bearing capacity of the rescue ladder stand is stronger, the transition platform meets the psychological needs of midway adjustment and rest, and therefore workers are safer to operate.

Description

technical field [0001] The invention relates to the technical field of elevating fire trucks, in particular to a fire truck for a climbing platform, in particular to a fire truck for a climbing platform with a rescue ladder on top of a transition platform. Background technique [0002] At present, there are two main arrangements for the boom of the climbing platform fire truck, the lower arm (or main arm) and the upper arm (or curved arm). One is arranged up and down, stacked together, the boom height is high, and the vehicle The height of the car is high and the volume is large; the other is that the upper arm (or curved arm) is installed on the side of the lower arm (or main arm). The combination of large bending and torsion loads deteriorates the stress situation; at the same time, in order to improve the driving stability and make the center of gravity of the vehicle in the retracted state, the deviation of the center of gravity is small. In the retracted state, the boom...
