How weight difference between what adjustment carriage and counterweight to save the energy used in elevator lifting, or is by elevator
Generated energy regenerating when carriage lifting operation, thus to reduce the energy consumption of elevator.When existing utilization elevator lifting
The movement of hoist ropes carries out the elevator of energy regenerating, is that the friction of hoist ropes is utilized to realize：Such as patent document 1,
Disclosed elevator energy storage device is provided with generating set 7 in shaft bottom, and the sliding of tensioned lines 6 when elevator lifting turns
It is changed to the rotation of generating set 7, and then electric energy is stored in electric capacity module 8；For another example patent document 2, disclosed electricity-saving
Ladder is provided with power generator 3 on wirerope 2, and when cage 1 is gone up and down, wirerope 2 carries out stretching motion up and down, benefit
With the frictional force of wirerope and generator power wheel 304, drives generator power wheel 304 to rotate, the weight in cage is utilized
Power potential energy, saves electric energy.Above two patent documents, hoist ropes is as elevator carries out when only considering elevator lifting
Lower movement, and energy regenerating is carried out using moving up and down for hoist ropes, there is no in view of elevator rope is on elevator
Lower movement can equally generate the vibration of horizontal direction；For another example patent document 3, it discloses a kind of elevator energy recyclable devices, should
Device be mainly used in elevator due to earthquake etc. and caused by hoist ropes vibration it is severe when, reduce the horizontal shake of hoist ropes
It is dynamic, and when causing hoist ropes horizontal vibrating severity due to wind or earthquake etc., hoist ropes horizontal vibrating is produced
Raw energy is collected.But in patent document 3, there is no in view of in elevator, when being operated normally, hoist ropes is deposited
Periodic horizontal vibration, be only in hoist ropes strenuous vibration, collect its shake energy, not targetedly, collect
Energy efficiency is low, and it belongs to a kind of passive process for collecting energy, can not be strong according to hoist ropes different location horizontal vibrating
The difference of degree, and corresponding energy recovery is carried out, in general, energy collection low efficiency is mainly still without specific aim
Reduction hoist ropes horizontal vibrating amplitude, rather than energy recovery is carried out for the horizontal vibrating of hoist ropes.For another example patent document
4-5, the rope energy collecting device being related to have used piezoelectric transducer material to be collected the vibration energy of rope, but
The piezoelectric material for having used price somewhat expensive, using piezoelectric material, with rope vibration, deformation occurs, produces electricl energy.
