Abstract

The invention relates to a motion mechanical energy storage and release device, in particular to an energy-saving lifting device which realizes smooth release by energy stored in a flat spiral spring. The device comprises a frame, an electric motor, a gear box, a loading box driven by a drum wire cable, and a drive shaft which drives the drum to rotate and is divided into a left section and a right section by the drum, wherein, one section is connected with the gear box by a clutch, and the other section is in parallel connection with a plurality of energy storage devices internally provided with the flat spiral springs by a plurality of the clutches. The energy storage device comprises a driven shaft, the flat spiral spring and the like, the driven shaft is a hollow shaft, the drive shaft passes through the driven shaft, the input end of the driven shaft is connected with the drive shaft by the clutch, after the clutch is closed, the driven shaft and the drive shaft synchronously rotate, thereby the energy storage devices can store or release energy when the loading box falls or rises. The device stores energy particularly when materials are unloaded in a mine and releases energy when the materials are lifted by the flat spiral spring, and the device has the advantages of high energy storage efficiency, stable lifting operation, being safe and reliable, and energy conservation.

Description

technical field [0001] The invention relates to a lifting device, in particular to an energy-saving lifting device which utilizes a planar scroll spring to store and smoothly release mechanical energy of motion. Background technique [0002] Most of my country's coal mines and other mines are either located in energy-concentrated areas or in quite scattered areas. In the actual operation of mine transportation, because the mine is generally deep, up to 800 meters, its potential energy is huge, and external power must be used to control the speed when the material is falling. The full use of gravitational potential energy requires a large amount of energy, resulting in a large waste of energy and operating costs. [0003] For the hoisting system of large and medium-sized coal mines, feedback power generation braking can be used to collect the mechanical energy during unloading, but for most small and medium-sized coal mines, the mechanical energy generated during the unloadi...
