Abstract

The invention discloses an elastic rubber band energy accumulator type loader movable arm potential energy recovery and regeneration device, and aims at providing a loader movable arm potential energy recovery and regeneration device which is high in energy conversion ratio, large in energy density, light in weight and simple in structure. The elastic rubber band energy accumulator type loader movable arm potential energy recovery and regeneration device comprises a front axle frame, a movable arm, a steel wire rope, a fixed pulley, an elastic rubber band energy accumulator and a hydraulic electromagnetic reversing valve. The elastic rubber band energy accumulator type loader movable arm potential energy recovery and regeneration device can realize recovery of gravitational potential energy of a working device and convert the gravitational potential energy into elastic potential energy to be stored in the elastic rubber band energy accumulator when the movable arm of a loader descends, and can convert the elastic potential energy stored by the elastic rubber band energy accumulator into gravitational potential energy of the movable arm when the movable arm of the loader lifts, so that recovery, regeneration and utilization of the potential energy of the movable arm of the loader and energy conservation and emission reduction are realized.

Description

technical field [0001] The invention relates to a potential energy recovery and regeneration device for a loader arm, more precisely, an elastic rubber belt accumulator type loader arm potential energy recovery and regeneration device. Background technique [0002] During the loading operation of the loader, the arm of the loader needs to be lifted and lowered frequently. During the lifting process of the arm, the engine drives the hydraulic pump to control the oil cylinder of the arm through the hydraulic reversing valve, and the arm together with the bucket and rocker Lift together to the unloading height. After the bucket is unloaded, the engine drives the hydraulic pump to control the boom cylinder through the hydraulic reversing valve, and lowers the boom, bucket and rocker to the loading height together. During the descent process, the engine is required to provide power, and the gravitational potential energy of the boom is wasted in vain, so that the loader has the d...
