Abstract
The utility model relates to a three-sectional arm folding type working device for a digging machine, which comprises a bucket (12), a connecting rod (11), a rocking rod (10), a bucket cylinder (9), a bucket rod (8), a bucket rod cylinder (5), an upper movable arm (4) and a movable arm cylinder (1). The utility model is characterized in that one connecting rod (7) is arranged between the bucket rod cylinder (5) and the bucket rod (8), one rocking lever (6) is arranged between the bucket rod cylinder (5) and the upper movable arm (4), and a lower movable arm (2) and a regulating cylinder (3) are arranged between the upper movable arm (4) and a base. The device has the characteristics that the utility model has lower center of gravity and large working range, and can raise the running stability of the complete machine and improve the running sight line of the complete machine, the running speed of the complete machine can reach more than 50 kilometers per hour, and the device can be used as the working device of the excavator.
Description
The utility model relates to the equipment that excavator is used, the collapsible equipment that particularly a kind of excavator is used.
Excavator is an engineering machinery relatively more commonly used, and particularly running type excavator purposes is extensive especially, and equipment is a requisite ingredient on the various excavators.The structure of the equipment on the present various running type excavator is three articulated types basically, promptly forms three telescopic structures between swing arm and pedestal, swing arm and dipper, dipper and the scraper bowl.There is certain problem in this three articulated equipments in application.Mainly be that excavator is when being in transport condition, center of gravity after whole equipment shrinks is higher, and stretch out side the place ahead at driver's cabin, for the riding stability of main frame and driver's the sight line of travelling very big influence is arranged all like this, restricted the travel speed of main frame, the F-Zero of this class excavator is no more than 35 kms at present.Owing to the angle of scalable adjusting between swing arm and pedestal, swing arm and dipper is less, the job area of equipment also is subjected to bigger restriction in addition.
The purpose of this utility model is, a kind of collapsible equipment of three joint arms that supplies excavator to use is provided, and this device center of gravity after folding is lower than three articulated type equipments, and does not influence main frame driver's the sight line of travelling; The job area of this device when operation is also big than three articulated type equipments.
The utility model is to realize like this.Its structure comprises scraper bowl (12), with connecting rod (11), rocking bar (10), the bucket cylinder (9) that scraper bowl (12) links, dipper (8), bucket arm cylinder (5), last swing arm (4), boom cylinder (1); Characteristics are, have increased a connecting rod (7) between bucket arm cylinder (5) and dipper (8), have increased a rocking bar (6) between bucket arm cylinder (5) and last swing arm (4); Between last swing arm (4) and pedestal, increase a downward moving arm (2) and regulated oil cylinder (3).
Compared with the prior art, the utility model has increased a downward moving arm and has regulated the joint that oil cylinder is formed between original swing arm and pedestal, and it is more flexible that joint between swing arm and dipper is regulated, and makes of the present utility model folding and launch performance and improve greatly.It is low to have folding back device center of gravity, can improve the stability that complete machine travels, and improves the sight line of travelling of complete machine, and travel speed is fast, the characteristics that job area is big.The complete machine travel speed can reach per hour more than 50 kms.The equipment that can be used as various excavators uses.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is an organigram of the present utility model;
Embodiment: the formation of the collapsible equipment of three joint arms that excavator is used comprises scraper bowl (12), with connecting rod (11), rocking bar (10), the bucket cylinder (9) that scraper bowl (12) links, dipper (8), bucket arm cylinder (5), last swing arm (4), boom cylinder (1); Characteristics are, have increased a connecting rod (7) between bucket arm cylinder (5) and dipper (8), have increased a rocking bar (6) between bucket arm cylinder (5) and last swing arm (4); Between last swing arm (4) and pedestal, increase a downward moving arm (2) and regulated oil cylinder (3).Device is installed on the main engine foundation, and two states is in use arranged.The one, transport condition: utilize to regulate stretching out of oil cylinder (3), the angle between swing arm (4) and the downward moving arm (2) is diminished, simultaneously bucket arm cylinder (5) is regained, change the position of dipper (8), three joint arms (be dipper, upward swing arm, downward moving arm) are folded.Because the equipment center of gravity after folding is very low, and the last plane of device is lower than driver's observation place, therefore can improve the stability that complete machine travels, and improves the sight line of travelling of complete machine, makes the quickening of main frame travel speed.The 2nd, duty: will regulate oil cylinder (3) and regain, and make the angle between swing arm (4) and the downward moving arm (2) become big, last swing arm (4) opens; Operation boom cylinder (1) promotes whole device or descends; Handling bucket arm cylinder (5) makes dipper (8) shrink or stretch out; Handling bucket cylinder (9) cuts the earth or unloading scraper bowl (12).
Claims (1)
1, the three joint arms collapsible equipments used of excavator comprise scraper bowl (12), with connecting rod (11), rocking bar (10), the bucket cylinder (9) that scraper bowl (12) links, dipper (8), bucket arm cylinder (5), last swing arm (4), boom cylinder (1); It is characterized in that: between bucket arm cylinder (5) and dipper (8), increased a connecting rod (7), between bucket arm cylinder (5) and last swing arm (4), increased a rocking bar (6); Between last swing arm (4) and pedestal, increase a downward moving arm (2) and regulated oil cylinder (3).
