Specific embodiment
It is specific embodiments of the present invention and with reference to attached drawing below, technical scheme is further described,
But the present invention is not limited to these embodiments.
As shown in Figure 1, a kind of lifting arm axis pin of the present invention, bearing replacing device, including pedestal 10, revolving platform 20, first
Linking arm 30, the second linking arm 40, fixed frame 50, adjustable shelf 60 and top-pushing mechanism 70.
Pedestal 10 is horizontally disposed, and revolving platform 20 is rotationally connected on pedestal 10 and energy opposite base 10 rotates, and first connects
It connects 30 one end of arm to be connected by axis pin with revolving platform 20, the other end is connected with the first saddle arm 31, and 40 one end of the second linking arm is arranged
In on axis pin, the other end is connected with the second connection saddle arm, and axis is both provided between the first linking arm 30, the second linking arm 40 and axis pin
It holds, fixed frame 50 is located at 10 one side of pedestal, and fixed frame 50 is used to support the first saddle arm 31, and adjustable shelf 60 is located at 10 opposite side of pedestal
And the second saddle arm 41 is used to support, the 60 energy opposite base 10 of adjustable shelf moves and closer or far from pedestal 10, top-pushing mechanism
70 is opposite with axis pin, and axis pin and bearing can be ejected and make the first linking arm 30 by top-pushing mechanism 70, the second linking arm 40 is with turning round
Platform 20 separates.
During replacement, first saddle arm 31 is held by fixed frame 50, by or adjustable shelf 60 second saddle arm 41 is held, this
When, gravity reduces, and the first linking arm 30, the second linking arm 40, revolving platform 20 and the frictional force of axis pin are smaller, pass through top-pushing mechanism
70, axis pin can easily be ejected, and bearing also removes revolving platform 20 together with axis pin, so as to fulfill the first linking arm 30,
Two linking arms 40 are separated with revolving platform 20, then, are moved by adjustable shelf 60, make the second saddle arm 41 away from revolving platform 20, with side
Just axis pin and bearing are replaced.
On the basis of said structure, the present invention is further improved it.
