Movable arm self-locking mechanism and application of movable arm self-locking mechanism on loading excavator
The invention discloses a movable arm self-locking mechanism and application of the movable arm self-locking mechanism on a loading excavator, the movable arm self-locking mechanism comprises a mounting seat, a movable arm and a telescopic arm, the lower ends of the movable arm and the telescopic arm are respectively hinged to a hinge point A and a hinge point B at different positions on the mounting seat, the point A is in front, the point B is in back, the upper end of the telescopic arm is hinged to a hinge point D on the movable arm, and the lower end of the telescopic arm is hinged to a hinge point D on the movable arm. The space position of the hinge point D can be changed through stretching and retracting of the telescopic arm, and when the points A, B and D move to the same straight line, the movable arm tends to rotate backwards under the action of gravity. According to the movable arm self-locking mechanism, the working dead point of the structure of the movable arm movement mechanism is broken through, falling of the movable arm oil cylinder is reversely utilized, and the purpose of movable arm self-locking is achieved.
本发明公开了一种动臂自锁机构及其在装载挖掘机上的应用，动臂自锁机构包括安装座、动臂和伸缩臂，动臂和伸缩臂的下端分别铰装在安装座上不同位置的A、B两个铰点，A点在前，B点在后，伸缩臂上端与动臂上的铰点D铰接，伸缩臂的伸缩会改变铰点D的空间位置，当A、B、D三点运动至同一直线时，动臂在重力作用下具有向后转动的趋势。本发明的动臂自锁机构突破动臂运动机构自身结构的工作死点，反向利用动臂油缸的下掉，达到动臂自锁的目的。
