Abstract

The invention discloses a potential energy recycling device with a compressed spring energy accumulator for a movable arm of a loader. The potential energy recycling device comprises the compressed spring energy accumulator, an electronic control unit, an ascending gear switch of a control lever of the movable arm, a descending gear switch of the control lever of the movable arm and a hydraulic electronic reversing valve. The potential energy recycling device has the advantages that the potential energy recycling device for the movable arm of the loader is high in energy conversion rate and energy density and simple in structure, and is light, gravitational potential energy of the working device of the loader can be recycled when the movable arm descends, and is converted into elastic potential energy, the elastic potential energy is stored in the compressed spring energy accumulator and is converted into gravitational potential energy of the movable arm when the movable arm of the loader ascends, accordingly, the potential energy of the movable arm of the loader is recycled, and purposes of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to a potential energy recovery and regeneration device for a loader arm, more precisely, a pressure spring 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 disadv...
