Abstract

The invention relates to a high-rotation speed energy storage and power assisting device of a crane lifting mechanism, wherein the high-rotation speed energy storage and power assisting device comprises an energy storage device, a clutch, a power assisting device and a control device, wherein an energy storage device installation shaft with a higher rotation speed is added through a speed increasing gear at a power input shaft of a speed reducer or a gear box of the crane lifting mechanism; the clutch is capable of achieving linkage or separation of the power input shaft of the speed reducer or the gear box and the energy storage device installation shaft; the power assisting device is capable of transferring energy collected by the energy storage device to the power input shaft of the speed reducer or the gear box; when a sling load ascends, the clutch is opened and the energy storage device does not collect the energy and does not increase new rotational inertia of the lifting mechanism; when the sling load descends, the clutch is closed and the energy storage device collects potential energy released by the sling load while descending; the lifting mechanism drives the sling load ascend again, and the power assisting device transfers the energy stored by the energy storage device to the power input shaft. The high-rotation speed energy storage and power assisting device is beneficial to efficient energy storage and is capable of assisting the sling load in lifting.

Description

technical field [0001] The invention relates to a high-speed energy storage and booster device for a crane hoisting mechanism, in particular to a hoisting mechanism with a high-speed energy storage and booster device and a crane using the lifting mechanism of the high-speed energy storage and booster device. Background technique [0002] Cranes and some lifting mechanisms are used to lift heavy objects and realize their lifting motion in vertical space, and realize the storage and release of gravitational potential energy during the lifting and lowering process. In order to ensure the energy-saving utilization of the crane, it is necessary to install a high-speed energy storage and booster device. The high-speed energy storage and booster device refers to converting the energy released by lowering the hoisting weight into electrical energy and storing it when the hoisting hook, platform or cage and other attachments are lowered. The stored energy is released to assist the s...
