Abstract
The invention discloses a swinging device for an excavator. An upper frame body (5) is hinged with two pin shafts (11) on a machine body (6) through two pin shaft holes (10); an oil cylinder (4) is arranged between the machine body (6) and the upper frame body (5); the machine body (6) is also provided with a hollow shaft (15); a worm wheel (16) is rotatably sleeved on the hollow shaft (15) and is fixedly connected with a lower frame body (8); the machine body (6) is provided with a (18) which is driven corresponding to the worm wheel (16); and the machine body (6) is provided with a hydraulic motor (17) which is in driving connection with the worm (18). The swinging device allows a working device to not only rotate but also swing relative to a stick, has a simple structure and reliable performance, and is used for the excavator.
Description
Technical field
The present invention relates to a kind of slewing apparatus, be particularly useful for the linkage that power shovel is used, can make scraper bowl or other equipment can rotate the linkage that also can swing with respect to dipper.
Background technology
As shown in Figure 1, existing power shovel 1 and dipper 3 what be connected employing is quadric chain 2, 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 when rotatablely moving (axis of rotation is on the paper plane) perpendicular to the sideshake on the paper or on perpendicular to paper.
Summary of the invention
Technical problem to be solved by this invention provides a kind of equipment that can make can rotate the slewing apparatus for digging machine that also can swing with respect to dipper.
In order to solve the problems of the technologies described above, slewing apparatus for digging machine provided by the invention, upper frame is hinged by two bearing pins on two pin shaft holes and the body, between described body and described upper frame, be provided with oil cylinder, hole on the piston rod of described oil cylinder and the oscillating deck of described upper frame is hinged by bearing pin, also be provided with hollow shaft on the described body, worm gear rotatably is sleeved on the described hollow shaft, described worm gear is fixedlyed connected with lower frame, on described body, be provided with the worm screw with the corresponding transmission of described worm gear, on described body, be provided with the hydraulic motor that is connected with described worm-drive.
Cylinder body on the described oil cylinder and described body are hinged by bearing pin on the cylinder body and seat orifice, and described seat orifice is connected with bolt and described body side plate.
Adopt the slewing apparatus for digging machine of technique scheme, when the piston rod of oil cylinder stretched out or regains, piston rod promoted the active force of bearing pin to torque of bearing pin generation, so body rotates around bearing pin, also was the relative upper frame generation of scraper bowl rotation campaign; When the primer fluid pressure motor, power is by worm screw, worm gear, and the back of slowing down drives lower frame and rotates, and has 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.
For the ease of control to this slewing apparatus, electromagnetic hydraulic pressure reversal valve group 7 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 7 easily.
In sum, the present invention a kind ofly can make equipment can rotate with respect to dipper also to swing and slewing apparatus for digging machine simple in structure, dependable performance.

The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Referring to Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, upper frame 5 is hinged by two bearing pins 11 on two pin shaft holes 10 and the body 6, between body 6 and upper frame 5, drive with two oil cylinders 4, hole on the oscillating deck 12 of the piston rod of this oil cylinder 4 and upper frame 5 is hinged by bearing pin 13, hinged by bearing pin on the cylinder body and seat orifice 14 on cylinder body on the oil cylinder 4 and the body 6, seat orifice 14 usefulness bolts and body 6 side plates are connected.Also be provided with hollow shaft 15 on the body 6, worm gear 16 rotatably is sleeved on this hollow shaft 15, worm gear 16 is fixedlyed connected with lower frame 8 by bolt, on body 6, be provided with worm screw 18 with worm gear 16 corresponding transmissions, these body 6 one sides are provided with hydraulic motor 17, and this hydraulic motor 17 connects worm screw 18 by spline.
As shown in Figure 1, existing power shovel 1 and dipper 3 what be connected employing is quadric chain 2, 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 when rotatablely moving (axis of rotation is on the paper plane) perpendicular to the sideshake on the paper or on perpendicular to paper.
Referring to Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, when the piston rod of oil cylinder 4 stretched out or regains, the active force that piston rod promotes bearing pin 13 produced a torque to bearing pin 11, so body 6 rotates around bearing pin 11, also was that the rotation campaigns take place the relative upper frame 5 of scraper bowl; When primer fluid pressure motor 17, power is by worm screw 18, worm gear 16, and the back of slowing down drives lower frame 8 and rotates, and has 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.
For the ease of control to this slewing apparatus, electromagnetic hydraulic pressure reversal valve group 7 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 7 easily.
