Electric recycling and reusing energy-saving device for potential energy of excavator boom
The invention provides an electric recycling and reusing energy-saving device for potential energy of an excavator boom. The device comprises a boom (1), a boom hydraulic cylinder (2), a steel wire rope (4), a roller (5), a motor (6), a plurality of sensors, a controller and a battery; the roller (5) and the motor (6) are fixed to an upper turntable of an excavator; and a speed reducer is arrangedin the roller (5); the motor (6) is connected with the speed reducer through a shaft coupling; one end of the steel wire rope (4) is wound on the roller (5), and the other end of the steel wire rope4 is fixed on the boom (1) through a pull rod 3; and the battery is electrically connected with the motor through an inverter. The energy-saving device of the invention is simple in structure, small in size, light in weight, low in cost and high in reliability, the efficiency of a hydraulic system is improved, the heating phenomenon of the hydraulic system of the excavator due to oil temperature rise is avoided, the specification of radiator equipment arranged in the system is reduced, and the obvious energy-saving effect is achieved.
一种挖掘机动臂势能电动回收及再利用节能装置，包括动臂(1)、动臂液压缸(2)、钢丝绳(4)、滚筒(5)、电机(6)、若干传感器、控制器和电池，滚筒(5)和电机(6)固定于挖掘机上部转台，滚筒(5)中有减速器，电机(6)通过联轴器与减速器相连，钢丝绳(4)的一端缠绕在滚筒(5)上，钢丝绳4的另一端经拉杆3固定在动臂(1)上。电池经过逆变器与电机电连接。本发明的节能装置结构简单、体积小、重量轻、成本低、可靠性高，提高了液压系统的效率，避免了挖掘机液压系统因油液温度升高而导致的发热现象，降低了系统配备的散热器设备的规格，具有明显的节能效果。
