Abstract
The invention discloses a pin shaft connection rack with a buffer device. The pin shaft connection rack comprise a connection rack, a transition rack and a rotary rack which are hinged from front to back in sequence; the buffer device is also arranged between the transition rack and the rotary rack; the connection rack can rotate left and right oppositely to the transition rack, and the rotary rack can rotate up and down oppositely to the transition rack. Therefore, the phenomenon that the rotary rack and the other components are collided and interfered with one another is not generated when engineering machinery of using the connection rack climbs up and down. In addition, the buffer device is also arranged between the transition rack and the rotary rack; the buffer device can retard effects of a sudden variable load or an impact load on other components when a rear frame is affected by the sudden variable load or the impact load.
Description
Technical field
The present invention relates to a kind of link span, relate in particular to a kind of bearing pin link span with shock absorber.
Background technology
Adopt the construction machinery and equipment (for example development machine) of radial type link span, generally by front/rear frame relatively rotate realize left/right rotation to, usually connect by bearing pin or rotary disk between the front/rear frame.Yet, sometimes the construction machinery and equipment of these employing radial type link spans need to be in rugged site environment work, when slope climbing movement up and down, because rear vehicle frame can not be with respect to front vehicle frame gyroscopic movement up and down, thereby be easy to cause rear vehicle frame and the mutual interference and collision of other parts of front.In addition, when rear vehicle frame is subject to unexpected variable load and impact load, also easily other parts of front is formed and impact, thereby cause harmful effect.
Summary of the invention
The object of the present invention is to provide a kind of can about revolution, turn round and have the bearing pin link span with shock absorber of pooling feature up and down.
For achieving the above object, the invention provides a kind of bearing pin link span with shock absorber, comprise from front to back hinged successively link span, transition frame and turret mount, also be provided with shock absorber between described transition frame and the described turret mount, described link span can be with respect to turning round about described transition frame, and described turret mount can turn round up and down with respect to described transition frame.
Compared with prior art, bearing pin link span with shock absorber of the present invention comprises from front to back hinged successively link span, transition frame and turret mount, and link span can be with respect to turning round about transition frame, turret mount can turn round up and down with respect to transition frame, thereby realized link span about revolution and gyroscopic movement up and down, the phenomenon of the mutual interference and collision of other parts of turret mount and front can not appear in the construction machinery and equipment that therefore, uses this link span when slope climbing movement up and down.In addition, owing to also be provided with shock absorber between transition frame and the turret mount, when rear vehicle frame was subject to unexpected variable load and impact load, shock absorber can slow down the impact that unexpected variable load and impact load cause other parts of front.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in detail:
Referring to figs. 1 to shown in Figure 4, the bearing pin link span with shock absorber of present embodiment, comprise from front to back hinged successively link span 1, transition frame 2 and turret mount 3, also be provided with shock absorber 4 between transition frame 2 and the turret mount 3, link to each other by the first bearing pin 5 between transition frame 2 and the turret mount 3.Link span 1 can be with respect to transition frame about 2 revolutions, and turret mount 3 can turn round up and down with respect to transition frame 2.
Wherein, shock absorber 4 comprises buffering framework 401 and buffer pull rod 402 etc., turret mount 3 upper center are installed with the second ear seat 8, the right-hand member of buffering framework 401 links to each other with the second ear seat 8 by the 3rd bearing pin 9, transition frame 2 upper center are installed with the first ear seat 6, the left end of buffer pull rod 402 links to each other with the first ear seat 6 by the second bearing pin 7, the middle part, left side of buffering framework 401 has cross through hole 408, the right-hand member of buffer pull rod 402 passes cross through hole 408 to the right and deeply cushions in the framework 401, cover has Compress Spring 403 and the ladder collar 406 on the part that is positioned at buffering framework 401 of buffer pull rod 402, the ladder collar 406 is positioned at Compress Spring 403 left sides and its left side contacts with the left end inwall boss plane of buffering framework 401, the left end engage sleeves of Compress Spring 403 is on the ladder collar 406, the right-hand member of buffer pull rod 402 is equipped with jam nut 404, the left end of jam nut 404 is provided with boss 405, the right-hand member engage sleeves of Compress Spring 403 is on boss 405, have on the outside face of jam nut 404 six uniformly-spaced annular spread stir blind hole 407, each line of centers of stirring blind hole 407 is vertical with the line of centers of buffer pull rod 402, thereby can come tension-lock jack panel 404 by the lever that blind hole 407 is stirred in insertion.Because boss 405 and the ladder collar 406 cooperate with Compress Spring 403, so that Compress Spring 403 is more stable when flexible.
In addition, an end of an end of the first bearing pin 5, the second bearing pin 7 and an end of the 3rd bearing pin 9 are equipped with an annular groove, and each annular groove place all is equipped with the fixed dam 10 that cooperates with annular groove, thereby has effectively prevented the axial motion of bearing pin.
Above embodiment is described preferred implementation of the present invention; be not that scope of the present invention is limited; design under the prerequisite of spirit not breaking away from the present invention; various distortion and improvement that the common engineering staff in this area make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
