Description
Technical field
It is a kind of step device that fire fighting truck independence crew department gets on the bus the utility model is related to arrive fire fighting truck field.
Background technology
In recent years, with the continuous development of megapolis, urban construction scale is increasing, and intensive degree is increasingly
Height, to urban fire control work, higher requirements are also raised, and in order to more efficient fire extinguishing, the people's lives and property is damaged
Mistake is preferably minimized, and more and more high-tech fire-fighting vehicle equipment military services fire brigade, the import chassis of performance brilliance, which becomes, to disappear
The first choice of anti-army, not destroy import chassis cab body structure, import chassis refit fire fighting truck generally use independently multiplies
Member's cell structure, i.e. driver's cabin are completely independent with back occupant room.Due to being related to some professional standards, while to meet fire fighter's peace
Entirely, it quickly gets on or off the bus, traditional structure is that the driver of driver's cabin gets off to open and marks time, and the indoor personnel of independent members get off；On
Che Hou, driver close and mark time, vehicle traveling.Traditional structure operation is extremely inconvenient, and influence time.
Invention content
The purpose of this utility model is to provide for a kind of step device that fire fighting truck independence crew department gets on the bus.In crew department
Portion, from inside opening car door, while car door opening, get on the bus mark time will automatic turning turn on, need not be in outside by external force
It opens, personnel can be immediately under car to ground, and closed door, overturning is marked time and will be automatically retracted, with car body with wide, vehicle
It can normally travel.
The utility model is achieved like this：A kind of step device that fire fighting truck independence crew department gets on the bus, it is characterized in that
Independent crew department is that fireman takes space, each side installs a winnowing machine door, and travel switch is equipped with per pair doorframe, independent
Crew department lower part is welded with lower storehouse, and the tops Xia Cang are equipped with fixed pedestal, cylinder upper bracket, active pedal upper bed-plate, servo-actuated pedal
Mounting base；Servo-actuated pedal is connect by bolt with servo-actuated pedal mounting base, and bolt is not fully locked, free to rotate；Actively
Pedal lower bottom base, cylinder undersetting are mounted on active pedal upper surface, between active pedal lower bottom base and active pedal upper bed-plate
Hinged by axis pin, active pedal can be freely driven；Cylinder is connect with cylinder undersetting, cylinder upper bracket respectively；Active pedal
It is connect by connecting rod between servo-actuated pedal, is servo-actuated pedal bottom and snubber block is installed.
By adopting the above-described technical solution, high degree of automation, pedal opens, improves operation effect automatically when car door opening
Rate saves fire fighter's muscle power.

Specific implementation mode
The utility model is described in further detail with example below in conjunction with the accompanying drawings.
In Fig. 1, independent crew department 1 is that fireman takes space, each side installs a winnowing machine door 2, per pair doorframe
Travel switch 3 is installed, 1 lower part of independent crew department is welded with lower storehouse 15, and the tops Xia Cang are equipped with fixed pedestal 4, cylinder upper bracket
14, active pedal upper bed-plate 11, servo-actuated pedal mounting base 5；Servo-actuated pedal 6 is connect by bolt with servo-actuated pedal mounting base 5, spiral shell
Bolt is not fully locked, free to rotate；Active pedal lower bottom base 10, cylinder undersetting 12 are mounted on 9 upper surface of active pedal,
Hinged by axis pin between active pedal lower bottom base 10 and active pedal upper bed-plate 11, active pedal 9 can be freely driven；Cylinder 13
It is connect respectively with cylinder undersetting 12, cylinder upper bracket 14；It is connected by connecting rod 8 between active pedal 9 and servo-actuated pedal 6, with
Dynamic 6 bottom of pedal is installed by snubber block 7.
From inside opening car door 2, when car door opening, 3 contact return of travel switch, cylinder 13 controls reversal valve and obtains electric, gas
Cylinder 13 is retracted, and drives active pedal 9 to be overturn to horizontal position by upright position, active pedal 9 will pass through connecting rod 8 while overturning
Servo-actuated pedal 6 is imparted power to, remains parallel position between two pedals, after active pedal 9 is completely parallel to the ground, with
Dynamic pedal 6 is also parallel to the ground, in addition fixed pedestal 4, the height of three-level pedal complies fully with standard requirement, facilitates fire fighter
To ground under independent crew department.After fireman gets on the bus, 1 car door 2 of independent members room is closed from inside, door side will be pushed down mounted in door
Travel switch 3 on frame, travel switch contact disconnect, and cylinder 13 controls reversal valve dead electricity, and cylinder 13 stretches out, and active pedal will be
Under 3 thrust of cylinder from horizontal position to upright position overturn, and by connecting rod 8 push be servo-actuated pedal 6 from horizontal position to
Upright position is overturn, and cylinder 13 is fully extended, active pedal 9 and vertical, i.e., consistent with width of the carbody, the vehicle completely of servo-actuated pedal 6
Normally travel.
