Structure.
Background technology
Wheel Engineering, by taking loading machine as an example, the action of its equipment is completed by steerable system.Common
Steerable system is broadly divided into mechanical manoeuvring system and hydraulic control system, and difference lies in the side for controlling multiple directional control valve for the two
Formula.Mechanical manoeuvring system, its operating mechanism are generally made of multiple control sticks and manipulation stent, are pulled by using operating mechanism
Operation flexible axle controls multiple directional control valve；Hydraulic control system, its operating mechanism are generally the pilot valve that can be swung with cross, led to
Cross using the guide oil of pilot valve to control multiple directional control valve, multiple directional control valve drives equipment complete by high pressure liquid pressure oil again
Into various actions.
Fig. 1 is a kind of mechanical manoeuvring system of the prior art, i.e., pulls flexible axle 2 using rigid control stick 3, pass through flexible axle
2 carry out control machinery formula multiple directional control valve 1, and then realize that boom arm lift declines the shovel loading or unloading material with scraper bowl.But it is mechanically operated by
In system, it usually needs different control sticks is utilized respectively to control the lifting decline of swing arm and the shovel loading and unloading material of rotating bucket,
I.e. driver need to first pass through manipulation swing arm control-rod and move back and forth to control the lifting and decline of swing arm, then by controlling rotating bucket to grasp
Vertical pole is moved back and forth to control the shovel loading and unloading material of rotating bucket.In this way, driver just needs to be replaced as frequently as control stick in operation,
Easily produce driving fatigue.
Fig. 2 is a kind of hydraulic control system of the prior art, i.e., controls pilot control hose 5 using pilot valve 6, then lead to
Pilot control hose 5 is crossed to control hydraulic type multiple way reversing valve 4, and then realizes the shovel loading and unloading of boom arm lift decline or scraper bowl
Material.Although in hydraulic control system, the control crank of pilot valve can be swung by the cross of handle realizes that boom arm lift declines
And multiple functions such as rotating bucket shovel loading and unloading, but mechanical manoeuvring system is more inclined to according to Market Feedback, portions of client colony
The grip feeling of control stick, it is not high for the degree of recognition of pilot handle, and also pilot operation mechanism its cost is about mechanically operated by mechanism
3 to 4 times, if considering the oil sources (be usually float flux gear pump) of pilot operation mechanism, its cost is relatively mechanically operated by mechanism and increases
Add more.
Then, a kind of mono-lever control mechanism for mechanical manoeuvring system is developed -- controlled by an one control lever a variety of
Action, and avoid frequently being replaced between multiple control sticks, for meeting customer need, product type is enriched, lifts brand
