Lever force arm power assisting device of piston type hydraulic energy accumulator

Abstract

The invention discloses a lever force arm power assisting device of a piston type hydraulic energy accumulator, and belongs to the technical field of grain and oil processing hydraulic machinery. The lever force arm power assisting device of the piston type hydraulic energy accumulator comprises a hydraulic oil cylinder, wherein a lower cavity of the hydraulic oil cylinder is connected with a hydraulic pump station through a hydraulic oil pipe; and hydraulic oil enters the lower cavity of the hydraulic oil cylinder under the driving of an oil pump of the hydraulic pump station, and a piston rod of the hydraulic oil cylinder naturally rises. The lever force arm power assisting device of the piston type hydraulic energy accumulator further comprises a bottom plate, a supporting stand column, a force arm assisting lever, a pressurizing gravity block supporting frame and a pressurizing gravity block, wherein the force arm assisting lever is hinged onto the supporting stand column; the top of the piston rod of a hydraulic oil cylinder is hinged to the force arm assisting lever; the bottom of the hydraulic oil cylinder is hinged to the bottom plate; the right end of the force arm assisting lever is hinged to the top of the pressurizing gravity block supporting frame; and a pressurizing gravity block is installed at the bottom of the pressurizing gravity block supporting frame. The lever force arm power assisting device of the piston type hydraulic energy accumulator aims to solve the problems that a constant-pressure oil cylinder is limited and oil is insufficient due to the fact that an existing intermittent operation constant-pressure hydraulic system is unreasonable in pressurization stress mode, and is simple in structure, high in measurement accuracy, wide in application range and low in cost.

Description

Technical field [0001] The present invention relates to a armless power device of a hydraulic accumulator, belonging to the field of grain and oil processing hydraulic mechanical technology. Background technique [0002] At present, grain and oil processing industries are suitable for cylinder power supply equipment, including equipment such as roller, expander, crusher, hydraulic flap cooler and other cylinders. Due to the requirements of the process index, the hydraulic pressure is stable, and the main production is actually applied to two forms: one is the hydraulic pressure stable for the constant pressure pump station, the constant pressure oil pump output output; the second is the pressure section of the operational pumping station system, the pump station The hydraulic output is running within the pressure interval, the low pressure starts to the system oil supply, the high pressure stops to the system figure 2 . [0003] The constant pressure pump station is also divided ...
