Turn, when clutch 93 disconnects, engine 91 does not work.
Wherein, generator motor 92 are can both to make generator use, but also as the motor device that motor uses,
When being driven by engine 91, rotary motion is generated, produces electricl energy, is stored in battery 94 simultaneously, generator motor 92 is not
It can be that generator motor 92 provides electric energy by battery 94, driving generator motor 92 rotates when work.Battery 94 can also
To be plugged in by charging unit.
Present embodiment, using generator motor 92 and engine 91 as hybrid power, in the case where electricity abundance
It is environment friendly and pollution-free directly using electric energy as clean energy resource；When electricity is finished, engine 91 can use to drive electricity generation and electromotion
Machine 92 rotates, while working normally, moreover it is possible to allow generator motor 92 to generate electricity, and be stored in battery 94, therefore this hair
Bright energy conservation and environmental protection is capable of the advantage of overall engine and motor.
As the further preferred of present embodiment, connect for convenience, as shown in figure 9, chassis bracket 1 may include bottom
Disk connector 11, the chassis connecting piece 11 and the pedestal 2 are articulated and connected.
Wherein, left and right levelling device 5 and front and back levelling device 4 can be oil cylinder, cylinder isoline driving device, and straight line
Driving device is equipped with the travel switch for detecting linear drive apparatus distance of stretch out and draw back, and travel switch is connect with control device 7,
Data feedback for will test is to control device 7.
The running part 3 can be crawler belt or wheel, preferably crawler belt.As shown in figure 13, left and right levelling device 5 is illustrated
A kind of operation schematic diagram, when left side left and right levelling device 5 shrink when, drive left side running part 3 move up.Such as Figure 11
A kind of operation schematic diagram of front and back levelling device 4 is illustrated with Figure 12, wherein Figure 11 is shape when front and back levelling device 4 stretches out
State, Figure 12 are state when front and back levelling device 4 is shunk.
Wherein, the control device 7 may include processor and control valve connected to the processor, the control valve difference
Connection front and back levelling device 4 and left and right levelling device 5 and flow and flow direction for adjusting medium.Control valve can use electromagnetism
Valve.Processor can be single-chip microcontroller perhaps PLC or other universal processors, be mainly accepts angle detection device 6
Signal, and handled according to signal value, then issue instructions to front and back levelling device 4 and left and right levelling device 5.
When front and back levelling device 4 and left and right levelling device 5 are oil cylinder, cylinder, generally controlled by control valve, such as
Using solenoid valve, control the flow direction and flow of medium, one end of solenoid valve and oil cylinder the medium inlet and outlet of cylinder connect, it is another
End is connect with fuel tank.About the connection of solenoid valve, it is the common knowledge of this field, therefore repeats no more.
As shown in Figure 11 and Figure 12 and Fig. 2 and Fig. 3, the working principle of present embodiment is shown:
When descending slopes, angle detection device 6 detects angular inclination data, and by data feedback to processor, processor according to
Current tilt data calculate the angle for needing to adjust, and calculate the distance acted required for front and back levelling device 4, then send
For control instruction to control valve, control valve makes the movement of front and back levelling device 4 release its piston rod, rotates chassis bracket 1 counterclockwise,
Reach levelling effect；Similarly, when going up a slope, angle detection device 6 detects angular inclination data, and by data feedback to processing
Device, processor calculate the angle for needing to adjust according to current tilt data, calculate movement required for front and back levelling device 4
Then distance sends control instruction to control valve, control valve makes the movement of front and back levelling device 4 shrink piston rod, makes chassis bracket 1
It rotates clockwise, reaches levelling effect.About the connection of solenoid valve, it is the common knowledge of this field, therefore repeats no more.
Wherein, solderable ear connecting plate on pedestal 2 and running part 3, connecting rod 8 and left and right levelling device 5 pass through the otic placode on pedestal 2
It is hinged with pedestal 2 respectively, it is hinged with running part 3 respectively by the otic placode on running part 3, as shown in Figure 10, four are welded on pedestal 2
The symmetrical otic placode of block, otic placode are respectively articulated with a connecting rod 8 in two holes up and down, the other end of every connecting rod 8 respectively with walking
The hole that 3 upper ear plate of portion opens up is hinged, positioned at the opposite position in the hole that 2 upper ear plate of pedestal opens up and the hole that 3 upper ear plate of running part opens up
It is identical for setting, and such connecting rod and otic placode just constitute a parallelogram sturcutre, it can be ensured that connecting rod 8 is during rotation
Running part 3 does not rotate.5 one end of left and right leveling cyclinder and the hole for the top that 2 upper ear plate of pedestal opens up are hinged, the other end and row
It walks that the following hole that 3 upper ear plate of portion opens up is hinged, left and right leveling cyclinder 5 is made to be in the diagonal positions of parallelogram.Work as a left side
When right levelling device 5 is shunk, connecting rod 8 drives running part 3 to rotate clockwise, and when left and right levelling device 5 stretches, connecting rod 8 is driven
Running part 3 rotates counterclockwise, to form the difference in height of left and right running part 3, achievees the effect that leveling.
Wherein, left and right leveling mode can there are three types of: it is ipsilateral leveling, opposite side leveling and two sides level simultaneously, with front and back
For when levelling device 4 and left and right levelling device 5 are oil cylinder, when angle detection device 6 detects that chassis bracket 1 tilts, hair
The number of delivering letters gives control device 7, meanwhile, the travel switch feedback information on oil cylinder is to control device 7, and control device 7 is according to as follows
Several corresponding leveling modes of situation selection:
(1) when left and right stroke switch, which is all given to 7 oil cylinder of control device, shrinks signal in place, if chassis bracket 1 is left at this time
Incline, so that its stretching, extension is reached levelling effect then control device 7 can control left side oil cylinder, similarly, detecting will control when Right deviation
The oil cylinder stretching, extension of system right side reaches levelling effect, is at this moment exactly ipsilateral leveling.
(2) when left and right stroke switch is all given to 7 oil cylinder of control device stretching, extension signal in place, if chassis bracket 1 at this time
"Left"-deviationist makes its contraction reach levelling effect then control device 7 can control right side oil cylinder, similarly, will when detecting Right deviation
The oil cylinder contraction of control left side reaches levelling effect, is at this moment exactly opposite side leveling.
(3) when left and right stroke switch is all given to the not contracted signal in place of 7 oil cylinder of control device, left and right sides oil cylinder meeting
Simultaneously operation leveling, is at this moment exactly two sides while leveling.
(4) when side, travel switch is given to the contraction of 7 oil cylinder of control device in place, and other side travel switch is given to control device
The stretching, extension of 7 oil cylinders in place when, illustrate that 1 tilt angle of chassis bracket at this time has arrived the limit of prescribed limit, can not be leveled again, need
It shuts down.
