Specific embodiment
This utility model is described in further detail with reference to specific embodiment.
Embodiment：
As shown in figure 1, a kind of development machine of the present utility model moves power source, including the hydraulic oil container for oil storage
2nd, for oil transportation Variable plunger pump 3 and the travelling control handle 4 for controlling the walking of development machine 1,2 link variable of hydraulic oil container
The import of plunger displacement pump 3, Variable plunger pump 3 are started by diesel engine 31, outlet and 1 banked direction control valves 11 of development machine of Variable plunger pump 3
Oil inlet P connected by hydraulic hose 5a, signal control port Ls and the control mouth of Variable plunger pump 3 of banked direction control valves 11 pass through
Hydraulic hose 5b connects, and the first oil-out T1 of banked direction control valves 11 is connected by hydraulic hose 5c with hydraulic oil container 2, banked direction control valves 11
Second oil-out T2 is connected by hydraulic hose 5d with hydraulic oil container 2, the oil-in of travelling control handle 4 and subtracting for banked direction control valves 11
Force feed mouth connection, the oil-out of travelling control handle 4 are connected with the first oil-out T1.In practical operation, 4 energy of travelling control handle
The running motor 12 for enough changing control development machine 1 using oil pressure makes the action for turning to of retreating, and Variable plunger pump 3 can be according to
Pressure change inside banked direction control valves 11 changes feed flow, controls then translational speed.Whole device is producing by oil pressure
Power, it is possible to avoiding the explosion issues that power on/off Mars causes.Hydraulic hose is more convenient curling and transports than cable light weight
Send.
Hydraulic hose is formed by bundles of short flexible pipe docking.With the traveling of development machine 1, the Len req of hydraulic hose is total
Can be increasingly longer, but single flexible pipe always has the limitation of length, so still having in the face of prolongation problem.Hydraulic hose is by short soft
Pipe picks up the prolongation for obtaining can just solving the problems, such as overall length, and short flexible pipe bunchy can be soft by all hydraulic when being arranged on docking
Pipe extends simultaneously, docking facility, time-consuming.
As shown in figure 1, signal control port Ls is provided with pressure gauge 6.Pressure gauge 6 can intuitively show walking joystick
Whether 4 have pressure change when adjusting, it is ensured that pipeline does not have leakage problem, it is ensured that control successfully.
As shown in figure 1, oil absorption filter 7 is provided between hydraulic oil container 2 and Variable plunger pump 3.Oil absorption filter 7 being capable of mistake
The impurity in pressure oil is filtered, the normal work of each part in its whole pipeline of impact is prevented.
As shown in figure 1, the outlet of Variable plunger pump 3 is provided with the branch road toward the backflow of hydraulic oil container 2, branch road is provided with relief valve
8.The outlet of Variable plunger pump 3 has highest oil pressure, if there is blocking in pipeline, the outlet pressure of Variable plunger pump 3 can be very
It is fast to raise, so the position is easiest to pressure oil to occur and gushs because pressure is excessive, produce danger.Relief valve 8 is in oil pressure herein
Can close less than when safety value, and pressure release can be just opened when oil pressure exceedes safety value, make pressure oil return to hydraulic pressure
In fuel tank 2.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of design being created without departing from this utility model, can also make some deformations and improvement, these belong to practical
