Arm 1 is hinged, and hydraulic cylinder 6 is for driving working arm 1 relative to 7 pitching of rotating part.
Since working arm 1 can rotate in the horizontal plane with rotating part 7 and can pacify relative to 7 pitching of rotating part
The position of needs can be reached with the movement of working arm 1 mounted in the work department of one end of the separate rotating part 7 of working arm 1.
Above-mentioned work department includes workbench, is provided on working arm 1 by one end of the neighbouring rotating part 7 of working arm 1
The channel 1a extended towards workbench.Personnel and goods and materials can be transferred to by the channel 1a on extension ladder 4 and working arm 1 by ground
On workbench, ground can also be transferred to by workbench.
The bottom end of extension ladder 4 is connect with rotating part 7, the top of telescopic arm 4 adjacent to working arm 1 neighbouring rotating part 7 one
The upper surface at end, in order to which personnel or goods and materials shift between 1 upper channel 1a of extension ladder 4 and working arm.
In conjunction with shown in Fig. 1,2,3 and 5, working arm 1 and extension ladder 4 are installed in the top of rotating part 4, extension ladder 4 with
Bottom end and working arm 1 that rotating part 7 connects are located at the same side of the first hinge member 5, and extension ladder 4 is along close to the first hinge member
5 direction gradually upwardly extends, and 7 top of separate rotating part of extension ladder 4 is connect with one end of the neighbouring rotating part 7 of working arm 1.
The both ends of extension ladder 4 are triangularly arranged with the first hinge member 5, and extension ladder 4 is as working arm 1 is relative to revolution
7 pitching of portion and stretch, extension ladder 4 can constitute always connection rotating part 7 and working arm 1 on channel 1a between transition
Channel.Wherein, the structural schematic diagram for lying down the fire fighting truck of collapsed state when on vehicle frame, figure are in Fig. 2 shows working arm 1
3 show the structural schematic diagram of fire fighting truck of the working arm 1 in working condition when rising.
Extension ladder 4 is arranged in the side of working arm 1 and can be flexible with the pitching of working arm 1, is conducive to save empty
Between, simplify the structure of fire fighting truck.
Width direction of the extension ladder 4 with working arm 1 along working arm 1 is arranged side by side.Extension ladder 4 includes 41 He of extension ladder ontology
It is connected to the transitional footboard 42 of one end of the neighbouring working arm 1 of extension ladder ontology 41, transitional footboard 42 is in the width side of working arm 1
Upwards between extension ladder ontology 41 and working arm 1.
In conjunction with shown in Fig. 1,4 and 5, fire fighting truck further includes the mounting rack for being connected to the side of neighbouring extension ladder 4 of working arm 1
3, mounting rack 3 extends along the width direction of working arm 1 towards extension ladder 4.Mounting rack 3 is located at the lower section of transitional footboard 42.
Fire fighting truck further includes connecting rod 2, and one end of connecting rod 2 and mounting rack 3 are hinged, and the other end and transitional footboard 42 are hinged.
As shown in Figure 1, rotating part 7 includes the revolving platform 71 connecting with working arm 1 and is arranged side by side with revolving platform 71
Walk platen 72, the bottom end of extension ladder 4 is connect with platen 72 is walked.Working arm 1 and revolving platform 71 are hinged.
As shown in figure 4, extension ladder 4 includes deformable parallelogram sturcutre, opposite two of parallelogram are pushed up
The distance between point changes with the variation of the angle of its two adjacent sides, therefore deformable parallelogram sturcutre can
So that extension ladder 4 stretches with the pitching of working arm 1.
The parallelogram sturcutre of extension ladder 4 includes cross member 45, longitudinal component 46 and for connecting cross member 45
With the second hinge member 44 of longitudinal component 46.
Cross member 45 arranges that longitudinal component 46 can be swung in perpendicular in the horizontal direction, puts in longitudinal component 46
In dynamic process, cross member 45 can keep horizontal, in order to which personnel walk or shift goods and materials.

Ground, anti-skid structure include anti-slip hole.
According to the kinematic sketch of mechanism 4 of extension ladder 4 it is found that this mechanism shares 11 movable parts, wherein based on working arm 1
Moving part, remaining is driven member.16 low secondary (revolute pair) are shared, no higher pair.According to the freedom calculation formula of mechanism, this can be obtained
The freedom degree of mechanism are as follows:
W=3n-2P-H=3 × 11-2 × 16-0=1
Wherein:
The freedom degree of W --- mechanism；
The movable part number of n --- mechanism；
The low pair of P --- mechanism；
The higher pair of H --- mechanism.
According to theory of mechanics it is found that make mechanism realize that expected determine moves, freedom degree W must satisfy following two
Condition:
1, W > 0；
2, W number is equal to the active number of packages of mechanism.
By above-mentioned calculated result, the freedom degree of this extension ladder 4 is 1, consistent with the quantity of mechanism driving link, can be kept true
Fixed relative motion.
Drive extension ladder 4 flexible in the present embodiment, during 1 pitching of working arm, extension ladder is that quadrangle is hinged
Structure is generated according to the instability quality of quadrangle when the mounting rack 3 being welded on working arm does luffing movement with working arm 1
When displacement, entire extension ladder 4 will drive by the hinge that connecting rod 2 is connected to 4 upper end of extension ladder and be rearward unfolded, entire expansion is dynamic
Make to be to maintain with the movement of the luffing of working arm 1 synchronous.The kinematic sketch of mechanism of Fig. 4 extension ladder 4 thus.
In the present embodiment, fire fighting truck includes aerial ladder high-jetting vehicle, is arranged above platen 72 in walking for the side of revolving platform 71
Extension ladder 4, when 1 pitching of working arm, as hydraulic cylinder 6 extends, extension ladder 4 under the drive of mounting rack 3 and connecting rod 2,
Realize that function is received in synchronous exhibition.
As shown in figure 4, extension ladder 4 includes that pedestal 47, cross member 45, longitudinal component 46, pedal 43 and second are hinged
Component 44, each hinge can open anti-slip hole with flexible rotating, guarantee the safety of stile up and down on pedal 43.
The bottom end of extension ladder 4 is connect with platen 72 is walked, and the top of extension ladder 4 is connect with working arm 1, what working arm 1 stretched
Process drives the synchronous exhibition of extension ladder 4 to receive.To make working arm 1 under any change angle, one can be set up from working arm 1
To the rescue channel walked on platen 72, the development of emergency management and rescue work rapidly and efficiently is ensured.
The above is only exemplary embodiment of the present invention, are not intended to limit the invention, all in spirit and original of the invention
Within then, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
