Energy-saving structure for working part of engineering machinery
The invention provides an energy-saving structure for an operation part of engineering machinery, which can ensure that an energy accumulator always generates larger upward swinging moment on a swinging arm in the lifting process of the swinging arm, and has a good energy-saving effect. According to the energy-saving structure, the two ends of an energy accumulator are hinged to a swing arm and a machine body, the distance AC is larger than the distance AB among a hinge point B, located on the swing arm, of the energy accumulator, a hinge point A, located on the machine body, of the energy accumulator and a hinge point C, located on the machine body, of the swing arm; in the upward swinging process of the swinging arm relative to the machine body, the energy accumulator releases energy, the energy accumulator is gradually extended, namely the distance AB is gradually increased, the force F of the energy accumulator acting on the swinging arm is gradually reduced, and the distance S from a hinge point C to the force F is gradually increased; in the process that the swing arm swings downwards relative to the machine body, the energy accumulator stores energy, the energy accumulator is gradually contracted, namely the distance AB is gradually reduced, the force F of the energy accumulator acting on the swing arm is gradually increased, and the distance S from the hinge point C to the force F direction is gradually reduced.
本专利提供一种工程机械作业部节能结构，它能够在摆动臂的升降过程中保证蓄能器始终对摆动臂产生较大的向上摆动的力矩，节能效果好。该节能结构，蓄能器的两端铰接在摆动臂和机身上，蓄能器在摆动臂上的铰接点B，位于蓄能器在机身上的铰接点A和摆动臂在机身上的铰接点C之间，距离AC大于距离AB；在摆动臂相对于机身向上摆动过程中，蓄能器释放能量，蓄能器逐渐伸长即距离AB逐渐增大，蓄能器作用在摆动臂上的力F逐渐减小，铰接点C到力F方向上的距离S逐渐增大；在摆动臂相对于机身向下摆动过程中，蓄能器储存能量，蓄能器逐渐收缩即距离AB逐渐减小，蓄能器作用在摆动臂上的力F逐渐增大，铰接点C到力F方向上的距离S逐渐减小。
