The swinging device ensures that the digging bucket not only can be rotated, but also can be swung relative to a bucket rod.
Description
Technical field
The present invention relates to the linkage of a kind of power shovel (or other equipment) usefulness, particularly a kind of scraper bowl that can make can rotate the swinging device for digging bucket that also can swing with respect to dipper.
Background technology
As shown in Figure 1, existing power shovel 11 and dipper 33 what be connected employing is quadric chain 22, scraper bowl 1 is relatively rotating on paper with respect to the motion of dipper 3.When scraper bowl 1 need then can't be realized this function perpendicular to the sideshake on the paper or need rotatablely move the time on paper.
Summary of the invention
Technical problem to be solved by this invention is at the deficiencies in the prior art, to provide a kind of scraper bowl (or other equipment) that can make can rotate the slewing apparatus that also can swing with respect to dipper.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of swinging device for digging bucket, comprise upper frame 1, this upper frame 1 is hinged by two the 1st bearing pins 8 on two pin shaft holes 13 and the body 2, two oil cylinders 5 are housed between body 2 and upper frame 1, the sidewall of the cylinder part of this oil cylinder 5 and upper frame 1 is hinged by the 3rd bearing pin 15, the 2nd bearing pin 14 on piston rod and the body 2 is hinged, the 1st bearing pin 8 on the body 2 and the 2nd bearing pin 14 are on same plane, two axial lines is parallel to each other, also be provided with hollow shaft 11 on the body 2, worm gear 12 rotatably is sleeved on this hollow shaft 11, and worm gear 12 is fixedlyed connected with lower frame 4 by bolt, these body 2 one sides are provided with hydraulic motor 7, this hydraulic motor 7 connects worm screw 9 by spline, and this worm screw 9 is installed in the bottom of body 2, and is meshed with worm gear 12.
Compared with prior art, beneficial effect of the present invention is: the present invention is installed between scraper bowl and the quadric chain, when the piston rod of oil cylinder stretches out or regains, the active force that piston rod promotes the 2nd bearing pin 14 produces a torque to the 1st bearing pin 8, therefore body 2 rotates around the 1st bearing pin 8, also is the relative upper frame generation of scraper bowl rotation campaign; When primer fluid pressure motor 7, power drives lower frame 4 and rotates by worm screw 9, worm gear 12 after slowing down, also just realized rotatablely moving of positive and negative 360 degree of scraper bowl.Like this, further improved the flexibility of excavator work, and then improved operating efficiency and expanded the range of application of excavator.

The specific embodiment:
As Fig. 2-shown in Figure 8, the present invention includes upper frame 1, this upper frame 1 is hinged by two the 1st bearing pins 8 on two pin shaft holes 13 and the body 2.Two oil cylinders 5 are housed between body 2 and upper frame 1, and these oil cylinder 5 cylinder parts link to each other by the 3rd bearing pin 15 with the sidewall of upper frame 1, and the 2nd bearing pin 14 on piston rod and the body 2 is hinged.As shown in Figure 7, the 1st bearing pin 8 on the body 2 and the 2nd bearing pin 14 have a segment distance (can be regarded as bent axle) between two axial lines on same plane.
The bottom of body 2 is provided with a hollow shaft 11, and worm gear 12 is sleeved on the hollow shaft 11, and can be around these hollow shaft 11 rotations.Circumferentially arrange several bolts hole 12 on the worm gear 12, be fixed together with the lower frame 4 that is provided with corresponding bolt hole 12 by bolt.A side also is equipped with worm screw 9, hydraulic motor 7 in the bottom of body 2, and worm screw 9 is installed in the bottom of body 2 by two bearings, and is meshed with worm gear 12.Hydraulic motor 7 and worm screw 9 are connected by spline.
When the present invention uses, upper frame 1 of the present invention is fixedlyed connected with quadric chain 22 by bearing pin, lower frame 4 of the present invention is fixedlyed connected with scraper bowl 11 by bearing pin.When needs are swung, suppose that upper frame 1 is motionless, when the piston rod of oil cylinder 5 stretches out or regains, the active force that piston rod promotes the 2nd bearing pin 14 produces a torque to the 1st bearing pin 8, therefore body 2 rotates around the 1st bearing pin 8, also be that body 2 with respect to upper frame 1 the rotation campaign takes place, owing to scraper bowl 11 is fixedlyed connected with lower frame 4, so also upper frame 1 generation rotation campaign relatively of scraper bowl 11.When 11 rotations of needs scraper bowl, primer fluid pressure motor 7 makes its rotation, and power will pass through worm screw 9, worm gear 12, drives lower frame 4 and rotate after slowing down.Lower frame 4 links to each other with scraper bowl 11, therefore can realize rotatablely moving of positive and negative 360 degree of scraper bowl.
For the ease of control to this slewing apparatus, electromagnetic hydraulic pressure reversal valve group 3 is housed in the inside of slewing apparatus, be connected in the excavator driver's cabin by circuit, the driver can make slewing apparatus realize the rotation campaign by the control to electromagnetic hydraulic pressure reversal valve group 3 easily.
