Description
Technical field
The invention belongs to fire fighting device technical fields, and in particular to a kind of fire fighting truck with walking manner selection function.
Background technology
As is known in the industry, by the function and usage of fire fighting truck classification have fire fighting vehicle, airport crash fire vehicle, special apparatus,
Elevating fire truck and auxiliary fire vehicle, etc..Fire fighting vehicle has pumper apparatus, triple, foam truck and does
Powder fire fighting truck etc.；Airport crash fire vehicle is exclusively used in processing aircraft fire accident, can spray fire extinguishing agent under steam, including airport rescues
Help guide's fire fighting truck and rescue and relief work fire fighting truck etc.；Special apparatus has command and communication fire vehicle, Lighting tower fire vehicle, speedily carries out rescue work and rescue
Calamity fire fighting truck, reconnaissance fire vehicle, propaganda fire vehicle and smoke exhauster truck etc.；Elevating fire truck has Elevating platform fire truck, lifts
Height injection fire fighting truck and hook and ladder etc.；Auxiliary fire vehicle has water tanker, foam truck and rescue fire fighting truck etc.
Deng.
It is no lack of the technical information for being seen in fire fighting truck, such as CN101274127B in disclosed Chinese patent literature（It is a kind of micro-
Type fire fighting truck）、CN101766875B（Multipurpose high-pressure water mist fire truck）、CN101757753B（With the light of spray gun combination spray
Type high-pressure water mist fire truck）、CN103623528B（A kind of urban turbojet fire vehicle）、CN103958004B（Suitable for high level
With the fire fighting truck of high-rise building fire attack）、CN103599609A（Superabsorbent fire extinguishing pumper apparatus deeply）、CN103751931B
（Fire hose is laid with fire fighting truck automatically）And CN103935285B（A kind of two way rail dual-purpose multifunctional emergency rescue firefighting
Vehicle）, etc..
Being not limited to the common feature of fire fighting truck exemplified above is：Since the walking manner of fire fighting truck is by wheel sub-line
It walks, thus the adaptability of topography and geomorphology variation is more short of, i.e., there is fastidious property to topography and geomorphology.Such as be difficult to even can not
In such as wetland, marsh, forest, snowfield, the pole for seriously freezing road surface, slope, desert, grassland, the cliff of displacement, ditch and beach etc
Topography and geomorphology situation downward driving is held, to constrain the performance of itself function of fire fighting truck to a certain extent.
The walking manner of crawler type fire fighting truck substantially adapts to the row of aforementioned topography and geomorphology as a result of crawler belt
It sails, and the technical information of crawler type fire fighting truck can be seen in disclosed Chinese patent literature, as CN203264106U recommends
Have " a kind of crawler type high-power fire truck ", CN104740815A be provided with " full terrain crawler-type multifunctional fire-fighting truck " and
CN105031857A introductions have " a kind of novel crawler fire fighting truck ", although being not limited to the aforementioned patent enumerated has topography and geomorphology
The good strong point of adaptability, but there are following logical disadvantages：The wheel that the intrinsic walking function of fire fighting truck has been abandoned due to having removed, because
And make the walking function of fire fighting truck at not selectable uniqueness.However during fire fighting truck responding, routine is travelled on
Probability on road such as urban and suburban roads is generally significantly greater than the probability travelled on extreme topography and geomorphology road surface above-mentioned.Then, such as
Fruit is that fire department had not only been equipped with the fire fighting truck walked by wheel, but also equipment by the fire fighting truck of crawler travel, then having no to doubt
It asks the acquisition expenses that can result in waste of resources and significantly increase government to the fire-fighting equipment of fire department, can additionally give fire-fighting
Department's garage resource distribution and daily manage and protect make troubles, and technical solution described below is to produce in this background
Raw.

Since the operation principle and the course of work of forward and backward crawler travel assembly lifting cylinder 35,36 above-mentioned are mutually the same
And it is synchronous working, and since the operation principle of preceding crawler travel assembly 37 and rear crawler travel assembly is identical and that
This working condition is identical and is synchronous working.Thus applicant is below only to preceding crawler travel assembly lifting cylinder 35
And preceding crawler travel assembly 37 illustrates.
When fire fighting truck travels on the urban and suburban roads of conventional road such as relatively flat, controlled by the vehicle-mounted hydraulic on fire fighting truck
Crawler travel assembly lifting cylinder 35 works before mechanism makes, and preceding crawler travel assembly lifting cylinder column 351 is i.e. upward into cylinder body
Displacement, drive 371 uplink of hoisting cross beam, due to the bottom of preceding portal frame frong guide column 321 and back gantry frong guide column 331 be with
Welding manner and lifting lock piece 371 are fixed, that is to say, that since the left and right end of hoisting cross beam 371 is by welding manner point
It is not fixed with the bottom of forward and backward portal frame frong guide column 321,331, thus preceding crawler travel assembly lifting cylinder column 351 to
When upper displacement, hoisting cross beam 371 is driven to move up, before driving preceding portal frame frong guide column 321 and back gantry by hoisting cross beam 371
Guide post 331 shifts up.Since the front and back ends of wheel carrier 372 pass through the forward and backward cantilevered axle 3721,3722 of wheel carrier and forward and backward dragon respectively
The process that the lower end of door frame frong guide column 321,331 is fixedly connected, thus is shifted up in forward and backward portal frame frong guide column 321,331
Middle drive wheel carrier 372 shifts up simultaneously, drives guide wheel 373 and driving wheel 374 to shift up by wheel carrier 372, preceding crawler belt
377 when shifting up, and hanging distance is formed between terrace, to make entire creeper undercarriage 3 be not involved in walking, i.e., by
Forward and backward traveling wheel 21,22 takes on walking task.
When encountering such as wetland, marsh, snowfield that applicant is mentioned above, seriously freeze road surface, slope, desert, disconnected
When extreme section, that is, topography and geomorphology of precipice, ditch and beach etc, then pressing aforementioned inverse process, make under creeper undercarriage 3
Drop substitutes front walking wheel 21 by it, takes on walking task by preceding crawler belt 377 and rear walking wheel 22, and front walking wheel 21 is in
Exit the standby mode of work.Hydraulic drive motor 375 works in this state, is hydraulically operated motor drive shaft 375 and passes through spline
Spindle nose connector sleeve 37633 drives spline axle head 37631, half shaft-cup 3763 is driven by spline axle head 37631, due to half shaft-cup 3763
It is fixedly connected with wheel hub sleeve 3762, and since driving wheel 374 is solid by driving wheel screw 3741 and wheel hub sleeve ring flange 37621
It is fixed, thus when hydraulic drive motor axis 3751 drives spline axle head 37631 to move, half shaft-cup is driven by spline axle head 37631
3763, by half shaft-cup 3763 with runner hub set 3762, driving wheel 374 is driven by wheel hub sleeve 3762, preceding shoe is driven by driving wheel 374
Band 377 moves again and again around guide wheel 373 and driving wheel 374, and fire fighting truck is made to walk.
In conclusion technical solution provided by the invention compensates for the shortcoming in prior art, invention has been favorably accomplished
Task has faithfully fulfilled the technique effect that applicant refers in technical effect column above.
