Operating principle and process:
During lifting operating mode, the first locking device locking, the 9th revolute pair loses degree of freedom, and the second locking device is opened, the 12 revolute pair degree of affranchising, now driving lever is lifted scraper bowl to fall by the acting in conjunction of the first pull bar, bracing frame, the second pull bar and swing arm.When scraper bowl overturns separately operating mode, the first locking device is opened, the 9th revolute pair degree of affranchising, and the second locking device locking, the 12 revolute pair loses degree of freedom, under the now effect of driving lever by the first pull bar, bracing frame and the second pull bar, scraper bowl is overturn.
Outstanding advantages of the present invention is:
1. utilize connecting rod to replace hydraulic drive, solved traditional loader manufacturing cost high, maintaining cost is high, and noise is large, vibrates the shortcomings such as large.
2. by adopting locking device to realize loader mechanism, initiatively become born of the same parents' function on linkage, make loader to lock some revolute pair according to different operating modes, reduce degree of freedom in good time, thereby reduce, drive controllable motor quantity.Than other multiple degree of freedom controllable loading mechanism, the present invention only can complete multiple electric motors multiple degrees of freedom loading operation with a motor, has greatly reduced manufacturing cost, and has reduced the complexity of mechanism, is more applicable for loader and other engineering machinery.
3. driving lever type of drive is flexible and changeable, can select driven by servomotor, the multiple type of drive such as combination drive, and not only environmental protection, and be easy to realize Long-distance Control, reduce cost of labor.
4. utilize support bar to increase revolute pair, than other multiple degrees of freedom controllable mechanisms, still less, structure is more simple for the rod member number of use, and reliability is higher than other multi-connecting-rod mechanisms.
