Be not suitable for the off-network electricity generation system of smaller power.
Currently as 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, which reclaims the energy that storage is wasted,.Especially
In lifting mechanism hoisting heavy, big energy can be expended, this just needs that the consideration of this theory will be saved in rubber tyre gantry crane design
Wherein, lift heavy is transferred the energy discharged with power assisting device and is converted into electric energy by high rotating speed energy storage, realizes the recovery storage of energy, together
When realize the design concepts of energy-conserving and environment-protective.
The non-electricity crane problem encountered of current field work is that power consumption is big, and not by spent energy
It is rational to recycle.The energy storage that release is transferred lift heavy with power assisting device in high rotating speed energy storage gets up, and can improve
The utilization rate of energy.
In summary, the lifting mechanism of existing crane, not only power consumption is big, and does not account for recovery and the profit of energy
With.
The content of the invention
The purpose of this utility model is to provide high rotating speed energy storage and the power assisting device of a kind of crane hoisting mechanism, passes through tooth
The raising of wheel speed, and then increase the energy of storage, to solve the energy efficient of crane recovery problem.The utility model simultaneously
