Box loading wheel mechanism of box pulling device

Abstract

The invention discloses a box loading wheel mechanism of a box pulling device. The mechanism comprises a run-through shaft and a roller, wherein the run-through shaft is fixedly connected with the upper end on the rear side of a turning frame of the box pulling device; a wear-resistant ring is tightly arranged on the inner side in the middle cavity of the roller; the inner wall of the wear-resistant ring is sleeved on external circles of the two ends of the run-through shaft and is in running fit with the external circles; an inward convex baffle ring body is arranged outside the middle cavity of the roller; the inner surface of the baffle ring body is contacted with the outer end face of the run-through shaft; a connecting pin is penetrated in the middle of the two ends of the run-through shaft; the rear end head of the connecting pin is provided with a convex ring; a spacer ring is arranged between the inner surface of the convex ring and the outer surface of the baffle ring body; the front end head of the connecting pin is provided with a bolt member; and the bolt member is also inserted into the two sides of the run-through shaft. Due to adoption of the overall structure, long-span rigid connection is realized on the two sides during box loading, so the structure has high reliability; the wear-resistant ring structure is lined in the roller, so the flexibility of the roller during running is improved and the service life of the entire member is prolonged; the axial relative moment of the roller is limited by using the connecting pin and the bolt member, so the structure of the mechanism is simple; and an oil storage ring is internally arranged to prolong the service life of the mechanism.

Description

technical field [0001] The invention relates to the technical field of sanitation vehicles with detachable compartments in special work vehicles, in particular to an upper box wheel mechanism of a box pulling device. Background technique [0002] The function of the detachable garbage truck is that the garbage can can be loaded on the vehicle, dumped on the vehicle, and processed under the box, which is paired with the up and down operation of the garbage box. Wheel device, the general practice in the prior art is to match the upper box wheel to the tail end of the attached frame, that is, the upper box wheel has nothing to do with the overturning frame, such as the Chinese invention patent of CN200320114768.9 "Carriage Detachable Type Garbage truck "(notification number is CN2659836Y) is exactly this type of design. There is a lifting and unloading mechanism on the chassis of the car. The hook head of the lifting and unloading mechanism is hooked with the car body shackle ...

AI Technical Summary

Problems solved by technology

Setting the pulley at the rear of the sub-frame complicates the structure of the rear of the sub-frame. Here, while realizing the rotation and cooperation with the turning frame, it is also necessary to take into account how to assemble the upper box pulley; and when the garbage can is placed on the vehicle body , the dustbin cannot exert certain gravity constraints on components such as the overturn frame, that is, no effective self-constraint force has been formed, so the structure is not yet perfect
