Description
Technical field
The invention belongs to a kind of main valve assemblies of excavator, specifically, more particularly to a kind of ultra-large type excavator master
Valve assembly.
Background technology
The ultra-large type excavator of ultra-large type excavator, especially hundred ton or more, are mainly used in opening for large-scale mineral resources
The Large Constructions such as hair, large foundation construction, marine reclamation land engineering, are monopolized by foreign capitals brand for many years.Its own has concentrated digging
The state-of-the-art technology in pick machine field, therefore, equipment price are expensive, and core hydraulic pressure system price is even more high.Excavator hydraulic pressure
System is core control and the moving system of excavator, the fuel feeding circuit to each hydraulic action element and confession that define hydraulic pump
How oily mode, more hydraulic actuators assignment of traffic when acting and realize composite move simultaneously, determine excavator operation
When kinematics and dynamic (dynamical) characteristic, action be preferential and cooperation, interflow fuel feeding and straight line moving etc..
Currently, as excavator is by medium-and-large-sized excavator to ultra-large type excavator, tonnage constantly increases, mainly uses
Technical solution is to replace the main valve of stem diameter bigger, and to ensure that hydraulic system has enough flows, this results in valve body of main valve
Shape, weight, difficulty of processing constantly increase, the growth of the cost and price of hydraulic system also and then at double, meanwhile, research and development
Manufacture difficulty higher, quantity in stock are larger.
Invention content
It is an object of the invention to overcome drawbacks described above, a kind of ultra-large type excavator main valve assembly is provided, uses two
A small-sized valve assembly replaces a big valve assembly of script, is greatly saved cost, reduces research and development manufacture difficulty, breaks super
The situation that large excavator is monopolized.
The ultra-large type excavator main valve assembly, including main valve, main valve include swing arm one, swing arm bigeminy, dipper
One, dipper bigeminy, scraper bowl one and revolution one；Further include plate valve, plate valve includes swing arm three, dipper three, scraper bowl two
Connection and revolution bigeminy, swing arm one and swing arm bigeminy are in parallel with swing arm three, and dipper one and dipper bigeminy and dipper three are simultaneously
Connection, scraper bowl one is in parallel with scraper bowl bigeminy, and revolution one is in parallel with revolution bigeminy.
Further, the swing arm one and swing arm two of the scraper bowl one of the main valve, the scraper bowl bigeminy of plate valve and main valve
Join, the swing arm three of plate valve is controlled by scraper bowl guide and swing arm guide's assembly, and connect respectively with bucket cylinder and boom cylinder.
Further, the dipper one and dipper two of the revolution one of the main valve, the revolution bigeminy of plate valve and main valve
Join, the dipper three of plate valve is controlled by turning round guide and dipper guide's assembly, and connect respectively with rotary motor and bucket arm cylinder.
Further, the main valve includes that left lateral walks connection and right lateral and walks connection, and left lateral walks connection and right lateral walks connection and walks elder generation by left lateral
It leads and walks the control of guide's assembly with right lateral, and connect respectively with running motor.
Further, the main valve joins equipped with straight line moving.
Further, the main valve is equipped with spare.
Compared with prior art, the beneficial effects of the invention are as follows：
1, the present invention is in parallel with newly-increased plate valve using small-sized main valve used in medium-and-large-sized excavator, instead of existing large size
Traditional main valve solves traditional main valve bulky, fabricates difficult problem, reduces ultra-large type excavator hydraulic system
R＆D costs and manufacturing cost；
2, the hydraulic system of ultra-large type excavator and the hydraulic system of medium-and-large-sized excavator be not general in the prior art, this hair
It is bright to be coordinated using original main valve and newly-increased plate valve, make ultra-large type excavator hydraulic system and medium-and-large-sized excavator hydraulic system
A platform is shared, most of element is general, these universal components only need spare set of system, greatly reduce hydraulic pressure
The inventory of system；
3, ultra-large type excavator and medium-and-large-sized excavator hydraulic system is general, is more simplified using operation, hence it is evident that reduces
Labor intensity；
4, ultra-large type excavator and the hydraulic system of medium-and-large-sized excavator share identical complete machine big data, but also research and development
More energy are dropped in power match, pipeline optimization, noise reduction, prolonged the service life etc. by personnel, are further improved
Product various aspects of performance solves the situation that ultra-large type excavator is monopolized by foreign capitals brand.
