Tension spring energy accumulator type loader swing arm potential energy recycling and regenerating device

Abstract

The invention discloses a tension spring energy accumulator type loader swing arm potential energy recycling and regenerating device, and aims to provide a loader swing arm potential energy recycling and regenerating device which is high in energy conversion rate, high in energy density, light in weight and simple in structure. The tension spring energy accumulator type loader swing arm potential energy recycling and regenerating device comprises a front axle frame, a swing arm, a steel wire rope, a fixed pulley, a tension spring energy accumulator and a hydraulic electromagnetic reversing valve. According to the tension spring energy accumulator type loader swing arm potential energy recycling and regenerating device, in the process that the swing arm falls down, a loader can recycle gravity potential energy of a working device; the gravity potential energy is converted into elastic potential energy and is stored in the tension spring energy accumulator; in the process that the swing arm of the loader is lifted, the elastic potential energy stored in the tension spring energy accumulator is converted into the gravity potential energy of the swing arm, so that the potential energy of the swing arm of the loader can be recycled and regenerated; and the aims of saving energy and reducing the emission are fulfilled.

Description

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