Description of the drawings
Fig. 1 is the side view of the embodiment of the present application.
Fig. 2 is the vertical view of the embodiment of the present application.
Specific implementation mode
It is described in further detail below in conjunction with the accompanying drawings and by embodiment to the application, following embodiment is to this Shen
Explanation please and the application is not limited to following embodiment.
Referring to Fig. 1 and Fig. 2, cylinder tube 5, hard tube 3 and oil pipe 4 are provided in the first arm 1, the left end of hard tube 3 is fixed
It is welded on the cylinder tube 5 in the first arm 1, the left end of cylinder tube 5 is mounted on by axis in the first arm 1, cylinder tube 5
Right side is provided with cylinder piston rod 51, and the right side of cylinder piston rod 51 is fixedly connected with the second arm 2, and the left end of the second arm 2 is set
It sets in the first arm 1, under hydraulic oil driving, the stretching of cylinder piston rod 51 or the stretching or retraction of the second arm 2 of drive of retracting,
Hard tube 3 includes the first hard tube 31 and the second hard tube 32, and the left end of the first hard tube 31 is weldingly fixed on the cylinder tube in the first arm 1
On 5,31 right end of the first hard tube is connect by first connecting portion 71 with the first oil pipe 41, and the left end of the second hard tube 32 is weldingly fixed on
On cylinder tube 5 in first arm 1,32 right end of the second hard tube is connect by second connecting portion 72 with the second oil pipe 42.
Grade ring 6 is additionally provided in the second arm 2, shelves ring 6 is arranged in the lower part of cylinder tube 51, and shelves ring 6 is welded on second
On arm 2, shelves ring 6 includes first grade of ring 61 and second gear ring 62, and the first oil pipe 41 passes through first grade of ring 61 to connect the second arm 2, the
Two oil pipes 42 pass through second gear ring 62 connect the second arm 2, with this come avoid oil pipe 4 run away to during the motion it is other place without
It is moved by normal trace, the first oil pipe 41 and the second oil pipe 42 are fixed by pressing plate 8 and the second arm 2.
Specific working mode, under hydraulic oil driving, the stretching of cylinder piston rod 51 or the stretching for the second arm 2 of drive of retracting
Or retract, the first arm 1 is motionless, if the outreach of the second arm 2 is X, this section of oil pipe at tubing bending is connected to interconnecting piece
Length degree reduces X/2, and oil pipe 4 and two arms, 2 junction stretch out X, be similar to movable pulley mechanism, stretch out or retract in oil pipe 4
Cheng Zhong does not have relative friction movement between oil pipe 4 and the second arm 2, will not gall oil pipe 4.
Upper and lower, left and right position relationship described in embodiment is described with the upper and lower, left and right of Fig. 1.
Described in this specification above content is only to the application example explanation；Moreover, the application zero
The title that component is taken can also be different, done equivalent of all structure, feature and principles according to described in the application inventional idea or
Simple change is included in the protection domain of the application.
