It is required that it is also very harsh, be temporarily also not suitable for large-scale application.
Physics energy storage mainly has compressed-air energy storage, draw water energy storage and flywheel energy storage etc..For chemical energy storage, physics
Energy storage is more environmentally-friendly, green, is realized using natural resource.Physics energy storage has that scale is big, circulation is received the order long and running cost
Low advantage is used, but needs special geographical conditions and place, the limitation of construction is larger, and one-time investment expense is higher,
Be not suitable for the off-network electricity generation system of smaller power.
Currently with the fast development of China's economic, the energy and environmental issue become Chinese fast-developing main barrier
Hinder.Therefore while tapping a new source of energy, it is also highly important that how research reclaims the energy that is wasted of storage.Especially
In lifting mechanism hoisting heavy, big energy can be expended, this is accomplished by rubber tyre gantry crane design this theory by energy-conservation and considers
Wherein, the energy of lift heavy decentralization release is converted into electric energy by rotating speed energy storage high with power assisting device, realizes the recovery storage of energy, together
When realize the design concept of energy-conserving and environment-protective.
The non-electricity crane problem encountered of current field work is big power consumption, and not by spent energy
It is rational to recycle.Rotating speed energy storage high gets up the energy storage of lift heavy decentralization release with power assisting device, can improve
The utilization rate of energy.
In sum, the lifting mechanism of existing crane, not only consumes energy big, and do not account for recovery and the profit of energy
With.
The content of the invention
It is an object of the invention to provide a kind of rotating speed energy storage high of crane hoisting mechanism and power assisting device, turned by gear
The raising of speed, and then increase the energy of storage, problem is reclaimed with the energy efficient for solving crane.While the purpose of the present invention is also
It is the lifting mechanism that a kind of this rotating speed energy storage high of utilization and power assisting device are provided.

Power input shaft (11) is pacified the linkage of rotating shaft (12) or is separated with accumulator；The power assisting device (3) can collect accumulator (4)
Energy transmission on the power input shaft (11) of decelerator (1) or gearbox.
The effect that the present invention reaches is：Potential energy when rotating speed energy storage high can decline craning weight of same with power assisting device is most
Stored in the form of electric energy eventually, in this, as the process auxiliary drive energy in hoisting heavy stage again, the device is neither given
Rising mechanism increases new rotary inertia, is conducive to high-efficiency energy-storage, also can power-assisted lift heavy raising.
Specifically, when craning weight of same rises, being opened clutch (5) by control device, accumulator (4) is not collected
Energy, does not also increase new rotary inertia to lifting mechanism；When craning weight of same declines, accumulator (4) in charge mode,
Clutch (5) is closed by control device now, accumulator (4) collects the potential energy that lift heavy declines release；Lifting mechanism drives
When lift heavy rises again, accumulator (4) is in discharge mode, the energy transmission that now power assisting device (3) stores accumulator (4)
Onto power input shaft (11).
The raising that rotating speed energy storage high passes through gear rotational speed with power assisting device to illustrate the invention, and then increase gear storage
The advantage of energy, spy carries out following calculating and analyzes.
The energy that the gear of rotation is stored in the form of kinetic energy at a high speed can be expressed as.
E=1/2 mv 2=1/2 mr 2 ω 2=1/2 Jω 2,
In formula:v- gear edge linear velocity (m/s),mThe quality (kg) of-gear,JRotary inertia (the kgm of-gear2),ωThe angular speed (rad/s) of-gear.
Understand that the rotary inertia of the energy that has of gear and gear, gear angular speed square are directly proportional by above formula, thus
Understand that the method for improving gear energy storage capacity has the rotary inertia of increase gear and improves gear rotational speed.
Because the formula of pinion rotation inertia can be approximated to be：J=1/2 mr 2,
In formularThe radius of gyration (m) of-gear.
Understand that the method for increasing pinion rotation inertia has increase pinion rotation radius and increase gear quality by above formula, but
In should be tried one's best in the case where ensureing that energy capacity is certain in the case of the being typically designed quality and volume of reduction gear, so increasing
The method of gear storage energy is generally raising gear rotational speed.
It can thus be appreciated that the raising for passing through gear rotational speed, and then the energy of gear storage can be increased.
