21, rubber tyre 22 is arranged at 21 both ends of chassis, drives its traveling by chassis 21, piggyback pod 23 is arranged at the top of vehicle frame 11, makees
For the power resources of whole vehicle.
Railway steering 30 hoofing part and the main body turned in railroad mode as whole vehicle, including front steering
Frame 31 and trailing bogie 32, trailing bogie 32 are hydraulic-driven, the driving main body travelled when being railroad mode, and forecarriage 31 is
Follow-up steering frame, primarily serves the effect of guiding.
As shown in Figures 2 and 3, forecarriage 31 includes the first fixed seat 311A, the second fixed seat 311B, the first support arm
312nd, the second support arm 313, the 3rd support arm 314, preceding hydraulic cylinder 315, front beam 316, front-end bearing pedestal 317, front jockey wheel
318 and preceding drag link 319.First fixed seat 311A and the second fixed seat 311B is arranged side by side on vehicle frame 11, for fixing it
His component.First support arm 312, the second support arm 313 and the 3rd support arm 314 are to act the critical piece transmitted, first
312 one end of brace is articulated with the first fixed seat 311A, can be rotated around the first fixed seat 311A, the other end then with the second support arm
313 one end is hinged, both can relatively rotate, and one end of the other end and the 3rd support arm 314 of the second support arm 313 is hinged,
Both can also relatively rotate, and the 3rd support arm 314 and the hinged one end of the second support arm 313 are fixed on front beam 316 at the same time,
The other end of 3rd support arm 314 is articulated with the second fixed seat 311B, can be rotated around the second fixed seat 311B.Preceding hydraulic cylinder
The 315 driving main bodys for being lifted and being put down as forecarriage 31, preceding 315 one end of hydraulic cylinder are articulated with the second fixed seat 311B
On, the other end is then articulated with the first support arm 312 and the second support arm 313 is hinged place.The flexible meeting of preceding hydraulic cylinder 315
Drive the 314 corresponding rotation of the first support arm 312, the second support arm 313 and the 3rd support arm, and then by preceding hydraulic cylinder 315
Expanding-contracting action be converted into the spinning movement of the first support arm 312, the second support arm 313 and the 3rd support arm 314.Second support
One end that 313 and the 3rd support arm 314 of arm is hinged is fixed on front beam 316, thus, the first support arm 312, second
The action of 313 and the 3rd support arm 314 of brace can drive the raising and lowering of front beam 316.316 both ends of front beam are respectively hinged with
One front-end bearing pedestal 317, two front-end bearing pedestals 317 are symmetrical arranged, and front-end bearing pedestal 317 can carry out low-angle around 316 both ends of front beam
Swing, the synchronism of two 318 beats of front jockey wheel in the same side during adapting to pass through small curve radius on track.Each front axle
Opposite front beam 316 is respectively symmetrically connected with two front jockey wheels 318 in bearing 317, specifically, front-end bearing pedestal 317 and leading

Motor 55R, the equal power drive of four motors rotates, since the hydraulic fluid flow rate of system is certain, therefore speed meeting during fast mode
Twice of speed when being low-speed mode under square one.Motor rinse-system 56 includes a flushing valve 561 and a flushing is overflow
Valve 562 is flowed, flushing valve 561 and flushing overflow valve 562 are arranged between oil inlet 51 and oil outlet 52 after connecting, and rinse overflow valve
562 directly connect left back traveling motor 54L, it is right after traveling motor 55R before traveling motor 54R, left front traveling motor 55L and the right side.
When needing to be rinsed whole system, flushing valve 561 is opened, hydraulic oil can be by flushing valve 561 by rinsing overflow valve 562
Internal punching is carried out to traveling motor 55R before traveling motor 54R, left front traveling motor 55L behind left back traveling motor 54L, the right side and the right side
Wash, while when 561 operating pressure of flushing valve exceedes preset value, carry out overflow can be automatically opened up by rinsing overflow valve 562, to play
The effect of overload protection.In practical work process, there is a situation where hydraulic fluid leak or loss, in order to ensure liquid in whole system
Pressure oil oil mass it is constant, high low speed fluid power system 50 further includes spare an oily oil inlet 57 and multiple check valves 58, spare
Oily oil inlet 57 via check valve 58 directly connect left front traveling motor 55L and it is right before traveling motor 55R, therefore the hydraulic pressure in system
In the case that oil is reduced, reserve liquid pressure oil can via spare oily oil inlet 57 then by check valve 58 enter whole system it
In, to supplement the hydraulic oil of reduction in whole system, hydraulic oil that check valve 58 can be in anti-locking system flow backward to spare oil into
Hydraulic fluid port 57.In order to grasp the operating pressure of whole system in time, high low speed fluid power system 50 further includes an oil pressure sensor
59, oil pressure sensor 59 is arranged between oil inlet 51 and oil outlet 52, for detecting the operating pressure of whole system in real time, and
The pressure value detected is sent to monitoring center in real time.
The operation principle of the utility model：During highway pattern, forecarriage 31 and trailing bogie 32 rise and, by chassis
21 driving rubber tyres 22 travel, at the same control sweep disk 45 and garbage collection suction inlet 44 height highway pavement clean and
The collection of rubbish；During railroad mode, forecarriage 31 and trailing bogie 32 are put down, and chassis 21 rises to rubber tyre 22 and departs from rail
Face, vehicle traction traveling is carried out by the hydraulic drive of trailing bogie 32, while disk 45 and garbage collection suction inlet 44 are swept in adjustment
Height railway road surface and track are cleaned and the collection of rubbish.
The beneficial effects of the utility model are：By the lifting of forecarriage and trailing bogie, to complete highway and iron
The switching of the two kinds of driving modes in road, to realize the traveling on different roads；By sweeping the setting of disk and garbage collection suction inlet, come
The cleaning to highway or railroad track is completed, cleaning is more convenient, and sweeping efficiency higher；Pass through high low speed fluid power system
Setting, realize being switched fast for high low speed, and speed during fast mode can be twice of low-speed mode under square one.
It these are only the preferred embodiment of the utility model, be not intended to limit the utility model, it is all in the utility model
Spirit and principle within, any modification, equivalent replacement, improvement and so on, should be included in the protection model of the utility model
Within enclosing.
