A quick-change attachment connection mechanism

Abstract

The invention discloses a quick-changing accessory connecting mechanism. The quick-changing accessory connecting mechanism comprises a connecting mechanism body, a quick-changing oil cylinder, connecting pins, fixing mechanisms and limiting mechanisms. Two hook seats are connected to the left side and the right side of the upper end of a hinge frame, mounting plates are welded to the hook seats, and the limiting mechanisms are mounted on the mounting plates; a left guide sleeve and a right guide sleeve are arranged on the two sides of the bottom of the hinge frame, correspond to the positions of the hook seats in the vertical direction and correspond to the two ends of the quick-changing oil cylinder in the horizontal direction; a vertical plate is welded to the front end of the hinge frame, and a mounting hole is formed in the position, corresponding to the quick-changing oil cylinder, of the vertical plate; a mounting block matched with the mounting hole is arranged on a cylinder barrel of the quick-changing oil cylinder in a connected manner, and the front end of the mounting block is inserted into the mounting hole of the vertical plate of the connecting mechanism body; and free ends of piston rods at the two ends of the quick-changing oil cylinder are inserted into the tail ends of connecting pins and are locked through the fixing mechanisms. The front ends of the two connecting pins are movably sleeved in the left guide sleeve and the right guide sleeve of the connecting mechanism body.

Description

technical field [0001] The invention relates to a quick-change attachment connection mechanism, which belongs to the technical field of engineering machinery. Background technique [0002] Taking the loader as an example, with the rapid development of the economy and the continuous increase of the country's investment in infrastructure construction, the complex and changeable construction environment and operating conditions put forward more and more requirements for the loader, so the loader supporting The demand for various work tools is becoming more and more urgent. Multi-purpose quick-change attachments are no longer the special needs of foreign users, and domestic users are also paying more and more attention to the application of multi-functional attachments for loaders. [0003] The quick-change attachments for loaders are at the front end of the working link, using a connecting frame to realize the quick replacement of work tools (buckets, clamps, sliding forks, etc...

AI Technical Summary

Problems solved by technology

Therefore, the structure of the connecting frame of the quick-change attachment is complex and heavy, and the size is large in the forward direction of the main engine, which makes the center of gravity of the quick-change attachment move forward, resulting in a decrease in the breakout force of the main engine, a decrease in tipping capacity, and a decrease in the rated load capacity of the main engine. , affecting the overall performance of the host
