Description
Technical field
The present invention relates to machinery field, specifically a kind of excavator with swing arm dual-support structure.
Background technique
Excavator is also known as excavating machinery, is to be excavated to be higher or lower than the material for holding machine side with scraper bowl, and be packed into haulage vehicle
Or it unloads to the earthmoving machinery of rickyard.The material that excavator excavates is mainly soil, coal, silt and the soil after pre- pine
And rock.From the point of view of the development of engineering machinery in recent years, the development of excavator is relatively fast, and excavator has become engineering construction
In one of most important engineering machinery.Common excavator is all to use large arm, swing arm and the concatenated mechanism of scraper bowl in the market,
Oil cylinder is integrated on each arm, and scraper bowl weight is excavated and carried to such design so that swing arm plays the role of exerting a force simultaneously,
It is high to the oil cylinder performance requirement of driving swing arm, affect the promotion of Bucket capacity and Operating Weight.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of excavators with swing arm dual-support structure.
To achieve the goals above, the invention adopts the following technical scheme:
A kind of excavator with swing arm dual-support structure, including the first telescopic rod, triangular connecting plate, first connecting rod,
Two connecting rods, third connecting rod, the second telescopic rod, third telescopic rod, the 4th telescopic rod, scraper bowl, rack, the first sliding block and second are sliding
Block,
First telescopic rod one end is connected on the rack by revolute pair one, and the first telescopic rod other end is connected by revolute pair two
First jiao in triangular connecting plate is connect, second jiao of triangular connecting plate is connect by revolute pair three with first connecting rod one end, and first
The connecting rod other end is connected on scraper bowl by revolute pair four,
Second connecting rod one end is connected on the rack by revolute pair five, and the other end passes through revolute pair six and third connecting rod one end
Connection, the third connecting rod other end are connected on scraper bowl by revolute pair seven,
Second telescopic rod one end is connected on the rack by revolute pair eight, and the other end is connected to the second company by revolute pair nine
On bar,
Third telescopic rod one end is connected on the rack by revolute pair ten, and the other end is connected to second by revolute pair 11
On sliding block, the second slide block set is mounted on third connecting rod,
4th telescopic rod one end is connected on triangular connecting plate by revolute pair 12, and the other end is connected by revolute pair 13
It connecing on the first sliding block, the first slide block set is mounted on first connecting rod,
The third angle of triangular connecting plate is also connected in revolute pair six.
Compared with prior art, the present invention have the utility model has the advantages that
Present invention reduces the bearing loads of each rod piece, reduce the rotary inertia of complete machine, stable drive, no sideshake, essence
Degree is high, and rigidity is high and has good dynamic performance, each connecting rod and telescopic rod reasonable Arrangement, improves the balance of overall mechanism
Can, further improve the dynamic performance of mechanism.
