In order to solve the technical problem, the invention provides a support body structure of a loader auxiliary support.
The invention is realized by the following technical scheme: a loader auxiliary support body structure comprises an auxiliary frame and an auxiliary support body; the front side and the rear side of the auxiliary frame are respectively provided with a hinged plate II, the front side and the rear side of the auxiliary support supporting body are respectively provided with a pair of hinged plates I, and the hinged plates II are positioned between the pair of hinged plates I on the corresponding sides; the hinged plate II and the hinged plate I on the corresponding sides are respectively connected through a swinging frame pin shaft; a flange is fixed on the front side surface of the hinged plate II; the pin shaft of the swing frame penetrates through the hinge plate I, the flange and the hinge plate II, and the flange is positioned behind the hinge plate I on the front side; a fixed block which is matched with the front end of the pin shaft of the swing frame for limiting is fixed on the front side surface of the hinge plate I on the front side; the rear end of the pin shaft of the swing frame is tightly pressed on the hinge plate I at the rear side through a mounting washer and a slotted nut; and a cotter pin is arranged on the slotted nut.
It further comprises the following steps: the auxiliary frame further comprises a pair of mounting plates II, and mounting holes are formed in the mounting plates II; and two ends of the hinged plate II are welded and fixed on the mounting plate II on the corresponding side.
The auxiliary support body also comprises four mounting plates I which are correspondingly welded at the end parts of the two pairs of hinge plates I, and mounting holes are formed in the mounting plates I; the mounting plate I is mounted on a mounting plate III on a rear frame of the loader through a bolt.
The floor welding has between mounting panel I and the articulated slab I.
Compared with the prior art, the invention has the beneficial effects that:
in the use process, the auxiliary frame is stressed to push the front end (front side hinged plate I) of the auxiliary support supporting body through the flange, the front end (front side hinged plate I) of the auxiliary support supporting body pushes the swing frame pin shaft, and the slotted nut at the other end of the swing frame pin shaft pushes the rear end (rear side hinged plate I) of the auxiliary support supporting body. Therefore, in the process of movement, the front-end hinged plate I and the rear-end hinged plate I are stressed together, single-plate stress of the original structure is changed into double-plate stress, the load borne by each hinged plate I is greatly reduced, the possibility of breakage of the support body of the auxiliary support is reduced, and the reliability and the service life of the support body of the auxiliary support are improved;
the connecting part of the auxiliary support supporting body and the rear frame of the loader is in bolt assembly connection, when the auxiliary support supporting body is damaged and needs to be maintained, disassembled and replaced, the whole rear frame does not need to be replaced, only the auxiliary support supporting body needs to be disassembled from the rear frame, and the operation difficulty and the task load are greatly reduced.

Detailed Description
In order to make the technical problems solved, the technical solutions adopted and the technical effects achieved by the present invention clearer, the technical solutions of the present invention are further described below by way of specific embodiments with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the elements associated with the present invention are shown in the drawings.
Referring to fig. 1 to 7, a loader auxiliary support structure, a front side and a rear side of an auxiliary frame 1 are respectively provided with a hinge plate II 12, and a flange 14 is fixed on the front side of the middle part of the hinge plate II 12. And two ends of the hinge plate II 12 are welded and fixed on the mounting plate II 3 on the corresponding side. And the mounting plate II 3 is provided with a mounting hole.
The front side and the rear side of the auxiliary support supporting body 2 are respectively provided with a pair of hinge plates I11, and four mounting plates I9 are correspondingly welded at the end parts of the two pairs of hinge plates I11. A ribbed plate 10 is welded between the mounting plate I9 and the hinge plate I11. The mounting hole has been seted up on mounting panel I9, and mounting panel I9 passes through bolted connection and installs on mounting panel III 3 on the frame behind the loader.
The hinge plate II 12 of the auxiliary frame 1 is positioned between the two hinge plates I11 on the auxiliary support supporting body 2 on the corresponding side, and the swing frame pin shaft 5 sequentially penetrates through the front hinge plate I11, the flange 14, the hinge plate II 12 and the rear hinge plate I11 from front to back. The front side surface of the front side hinged plate I11 is fixedly provided with a fixed block 4 which is matched with the front end of the swing frame pin shaft 5 for limiting, and the fixed block 4 is used for limiting the circumferential rotation of the swing frame pin shaft 5. The rear end of the swing frame pin shaft 5 is tightly pressed on a hinge plate I11 at the rear side through a mounting washer 6 and a slotted nut 7, and a cotter pin 8 is mounted on the slotted nut 7.
The working process is as follows:
in the specific use process of the support body structure of the auxiliary support of the loader,
the force applied to the hinge plate II 12 of the auxiliary frame 1 is dispersed to the two hinge plates I11 of the auxiliary frame supporting body 2 through the swing frame pin shaft 5, the slotted nut 7 and the cotter pin 8. Therefore, in the process of movement, the hinge plates I11 jointly disperse load, the load born by the hinge plates I11 independently is reduced, the possibility of breakage of the auxiliary bracket supporting body is reduced, and the reliability and the service life of the auxiliary bracket supporting body are improved compared with the existing design;
in the aspect of maintenance, adopt assembled structure and install the welded structure of floor than current design additional in both sides, improved the flexibility and the reliability of structure, reduced the maintenance and dismantled and the degree of difficulty of changing.
