Detailed description of the invention
The total design of the present invention is: excavator uses oil electricity two set power, and makes two set engines series windings install.Below
Four kinds of embodiments are introduced in conjunction with accompanying drawing.
The first embodiment
As shown in figures 1-4, a kind of novel double power full hydraulic excavator is which described.As seen from the figure, this excavator is by vehicle frame
1, vehicle body 2 is constituted, and vehicle body 2 is positioned at above vehicle frame 1, and vehicle body 2 is connected by slewing equipment 3 with vehicle frame 1, and slewing equipment 3 can realize
By vehicle body 360 ° rotation；Vehicle frame 1 both sides are provided with running gear 4, and described running gear 4 is provided with running motor 4.1, and running gear can
Use wheeled, it is possible to use crawler type；Vehicle body 2 front portion is provided with equipment 5, the running gear 4 of described excavator and work
Device 5 is all hydraulically operated；Vehicle body 2 includes driver's cabin 2.1 and power bin 2.2 two parts, is provided with dynamical system in power bin 2.2
7, dynamical system 7 includes internal combustion engine 7.1 and 7.2 two kinds of power sources of motor, and described internal combustion engine 7.1 typically uses diesel engine, also
Gasoline engine can be used；For saving space and being easy to switching, two kinds of power sources take serial arrangement to install, internal combustion engine 7.1 and electricity
Motivation 7.2 is connected by main clutch 7.3, can be carried out the switching of power source by the folding of main clutch 7.3.
Described dynamical system 7 with the order of connection of hydraulic system 6 is: internal combustion engine, clutch, motor, hydraulic system, i.e.
The power of dynamical system 7 is directly output to the hydraulic pump of hydraulic system, controls by controlling the power output of engine
The ability to work of hydraulic system, makes the linking of two systems become simple, efficient, further increases the adaptation ability of equipment.
It addition, when only starting motor 7.2 and working, internal combustion engine 7.1 quits work, thus internal combustion engine 7.1 will be caused
Radiator fan stall, in causing power bin 2.2, temperature is too high, affects the normal work of hydraulic system.And if using and install wind additional
The mode of fan is that power bin 2.2 dispels the heat, and certainly will need to install extra equipment at vehicle body 2, this excavator on the one hand increased
Manufacturing cost, more importantly, the fan newly installed additional the fan original-pack with internal combustion engine can because the selection of power source and only one
Set fan is in work, another set of idle, causes the wasting of resources, and the wind inlet of fan of new clothes can have a strong impact in power bin 2.2
Air-flow trend, reduce engine radiating effect.
The present embodiment is provided with an auxiliary-motor 7.1.2 in the position of the original fan 7.1.1 of institute's internal combustion engine 7.1, and at wind
Fan clutch 7.1.3, fan 7.1.1 it is provided with by fan clutch 7.1.3 and internal combustion engine 7.1 in the rotating shaft of fan 7.1.1
Pto connect.Auxiliary-motor 7.1.2 is provided with fan clutch 7.1.3, and the axle sleeve of fan 7.1.1 rotating shaft is with secondary
On motor 7.1.2, clutch is in transmission connection mutually.Two fan clutch 7.1.3 are centrifugal clutch.When internal combustion engine 7.1 work
When making, it is driven by fan 7.1.1 and rotates, because auxiliary-motor 7.1.2 is coupling with fan 7.1.1 by centrifugal clutch, therefore
It will not rotate；Otherwise, motor 7.2 when driving excavator to work, main clutch 7.3 disconnects, and internal combustion engine 7.1 is not sent out
Raw rotation, now auxiliary-motor 7.1.2 starts, and drives fan 7.1.1 to rotate heat radiation, and the work of auxiliary-motor 7.1.2 will not drive interior
Combustion engine 7.1 rotates.
Described in the present embodiment excavator use hydraulic drive, described hydraulic system 6 include control station 6.1, hydraulic pump 6.2,
Pipeline 6.3；Control station 6.1 is located in driver's cabin 2.1；Hydraulic pump 6.2 is connected with the output shaft of dynamical system 7, and control station 6.1 leads to
Cross pipeline 6.3 to be connected with hydraulic pump 6.2, equipment 5, running motor 4.1.
The second embodiment
As shown in Fig. 5～6, on the basis of previous embodiment, the present embodiment is provided with drum 8 at the afterbody of described vehicle frame 1.Institute
Stating drum 8 and include base 8.1, take-up pulley 8.2, drum motor 8.3, cable 8.4, base 8.1 is fixing with vehicle frame 1 to be connected, take-up
Taking turns 8.2 axles to be connected on base 8.1, take-up pulley 8.2 is in transmission connection with drum motor 8.3, and the outer rim of take-up pulley 8.2 is provided with gear line wheel
8.2.1, cable 8.4 is looped around on take-up pulley 8.2.Described drum motor 8.3 coordinates with excavator operation sensor etc., can realize
Automatic deploying and retracting cable 8.4.
But under actual condition, excavator frame 1 be likely to relatively frequently left-right rotation, front and back retreat, make cable 8.4 innings
Portion bends with very small angles, easily causes the breakage of cable 8.4.Therefore, above-mentioned base 8.1 is also designed to fixed part
8.1.1 with rotating part 8.1.2 two parts, the two is hinged, and rotating part 8.1.2 is not in the case of touching running gear, permissible
Wide-angle swings, can effect strengthen cable 8.4 curve radius, slow down its strain.
The third embodiment
As shown in Fig. 7～10, on the basis of previous embodiment, for strengthening the ruggedness of cable 8.4 further, the present embodiment is also
Being provided with one layer of protective sheath 8.4.1 outside described cable 8.4, it can be made up of rubber and/or silica gel and/or wire netting,
Increase the wearability of cable 8.4.Furthermore it is also possible to arrange vertical rib 8.4.2 in protective sheath 8.4.1, to strengthen line
Cable contacts distance with ground.Rib 8.4.2 is longitudinally disposed along cable, its quantity can 1～12, and be evenly distributed in the form of a ring.
4th kind of embodiment
As shown in figure 11, on the basis of previous embodiment, drum motor 8.3 is arranged in hydraulic system 6 by the present embodiment, for
Giving full play to the performance of hydraulic system, new power source do not set up by drum motor 8.3, but places it in running motor 4.1
Hydraulic circuit in, and using the shift signal of running gear 4 as the operative orientation of drum motor 8.3, make the work side of the two
To unanimously.Switch and/or centrifugal clutch it is provided with, in order at only running gear between described drum motor and running motor
During work, control whether drum works, it is achieved the dynamic Control of drum.This arranges the mesh that on the one hand can reach to save the energy
, on the other hand can also simplify the signal conduction in drum 8 work process, both improve work efficiency, and saved again manufacture
Cost, operating cost.
Centrifugal clutch used in above-described embodiment, its structural principle is as shown in figure 12.Described centrifugal clutch 9
Having driving shaft 9.1 and passive axle sleeve 9.2, driving shaft 9.1 is provided with centrifugal body 9.3, driving shaft 9.1 is centrifuged body 9.3 when rotating
Radially throw away and compress with passive axle sleeve 9.2 inwall and transmit moment of torsion.
