Description
Technical field
The present invention relates to a kind of novel non-counterweight elevators, belong to elevator technology field.
Background technology
Elevator device is typically included in the compartment system of the up and down motion in hoistway and Weighting system is constituted.Car is that have sedan-chair
Frame and babinet two parts are combined into one the structure of formula, and middle case is supported by sedan-chair frame.Common elevator device includes electricity
Terraced car, driving device, traction rope and counterweight, wherein traction rope or other load-bearing parts are along in sedan-chair frame at appropriate position
Skidding is moved；Counterweight is usually supported with compartment system by traction rope or load-bearing part.While usually with car movement is focused on, edge
The guide rail for guiding counterweight moves up and down in hoistway.The weight of counterweight by compartment system itself weight and maximum load one
Half weight forms.The weight of compartment system constitutes the power T1 of traction sheave side, and independent balance weight constitutes traction sheave
The size of the power T2 of the other side, motor output torque are determined by the difference of T1 and T2, and the driving power of traction sheave needs
The value for meeting formula ef α >=T1/T2, f and α is system inherent characteristic, therefore the difference of T1 and T2 is smaller, motor output torque
It is smaller, the driving power of elevator device is required lower.
Real elevator device has the drawback that：
One, it economically sees, is on the one hand moved due to having to accommodate conventional with focusing in hoist-hole, hoist-hole needs
Additional space is designed, the waste of resource is caused；On the other hand, reach balance to greatest extent in different loads operating mode to reach,
No matter how how load changes the weight of counterweight, remains constant, usually by the weight of compartment system itself, in addition maximum load
Half weight form, make the weight weight of counterweight itself in this way, it is of high cost；Third, guide rail and assembling for guiding counterweight
Installation involved by these components, artificial and time related cost.
Two,, can only be closer better by the ratio of T1/T2 in order to reduce the requirement to driving power from the point of view of driving power,
The calculation formula of usual counterweight-side stress is：T1=(P+Q)/2, T2=(P+0.5Q)/2, in the case of compartment system zero load,
Keep T1: T2 ratio small, compartment system weight certainly will be required more again better, since the weight of counterweight is usually by compartment system sheet
The weight of body is formed plus the half weight of maximum load, so again require the weight of counterweight to increase, such driving power and
Most light compartment system, existing contradiction between optimal cost.T1: T2 ratio also with different load working conditions have it is larger
Difference.
Three, from a safety standpoint, lift car and with focus on move up and down in hoistway when, inevitably will produce a bit
Shaking shows, and in the case where the longer traction rope of work floor of the elevator is longer, such shaking phenomenon is one in time
In a very small angle, also due to the factor of length and bring terrible consequences.
Four, from the angle of energy, since current elevator device cannot accomplish that both sides completely balance, and are only carrying always
When lotus reaches 50%, energy consumption is minimum, and but regardless of being 0% in load or load is 100%, energy consumption reaches maximum value,
And elevator frequency of use it is high usually not near 50% load working condition, therefore energy cannot being optimal configuration.
Invention content
It is an object of the invention to overcome above-mentioned deficiency existing in the prior art, and provide a kind of economy, safety and energy
Measure the high novel non-counterweight elevator of recovery utilization rate.
Technical solution is used by the present invention solves the above problems：A kind of novel non-counterweight elevator, including control system,
The lift car and driving device lifted in hoistway, control system include safety return circuit, further include that energy storage device and energy are mended
It fills and sets；Elevator rail is equipped in the hoistway, the driving device includes several hydraulic motors one；The hydraulic motor one is equal
Cloth is matched in car both sides, transmission shaft end with elevator rail；The hydraulic motor one is connected to oil by high-pressure oil pipe one
On the controller of road；The oil circuit controller is mended with energy storage device and energy respectively by the branch one of high-pressure oil pipe two and branch two
It fills and sets connection, be connected on fuel tank by high-pressure oil pipe three；The energy storage device by fluid by cage descending when machinery
It can store, energy is provided for hydraulic motor one when car rises；The energy supplement device is connect with fuel tank, in car
When elevation energy deficiency, energy is supplemented for hydraulic motor one.
The uniformly distributed hydraulic motor one in lift car both sides is matched with the elevator rail in hoistway, drives car in hoistway
It moves up and down.The extraneous transmission shaft end that energy band hydrodynamic pressure motor one is provided is needed in the case of no counterweight, when car rises
It rotates to overcome gravity acting, to which mechanical energy is converted into the potential energy of car, while low pressure oil being stored in fuel tank；Car exists
When decline, it was also required to avoid car from forming excessive movement velocity under gravity car acting originally, and this hair
When declining, the transmission shaft end of hydraulic motor one still coordinates with elevator rail car in bright scheme, only its rotation direction
For rotation direction when rising with car on the contrary, therefore in cage descending, fluid can be passed through high-pressure oil pipe two by hydraulic motor one
It is reversely input in energy storage device, the potential energy reduced when by energy storage device by cage descending is that other energy storages are storing up
Can in device, on the one hand need not still further use energy can so that speed of the car when declining is in zone of reasonableness,
Generated energy has carried out rational recycling storage when on the other hand to cage descending.Oil circuit controller is planned as a whole control and is transferred to respectively
The oil mass of a hydraulic pressure prosperity one.The energy being stored in energy storage device, when car needs to rise, and can be back through high pressure oil
Pipe two is applied to again on hydraulic motor one, is provided energy for the rising of car, is substantially increased the capacity usage ratio of elevator.And
The unavoidable loss brought among these due to the conversion of energy is then supplemented by energy supplement device, is risen for car
Required energy provides guarantee.
Further, the energy storage device pumps for piston energy storage, including seals hollow shell and be arranged in shell
Isolation piston；The shell includes outer housing and inner housing, and the partial shell of inner housing is arranged in outer housing and and outer housing

Space in outer housing is divided into air compression unit and oil inlet portion two by the isolation piston, and the oil inlet portion two connects with logical oil valve
It connects.
Except being communicated except through logical oil valve between outer housing and inner housing, rest part is seal isolation state；
Isolation piston in outer housing makes the air compression unit in outer housing and isolation sealed to each other between oil inlet portion two again.Fluid is logical
It crosses logical oil valve to enter in oil inlet portion two from oil inlet portion one, isolation piston is pushed to press the air in air compression unit
Contracting, to complete energy storage；When energy exports, lead to oil valve and open, the pressure-air in air compression unit pushes isolation piston will
Fluid reversely pushs out, and fluid is acted on along high-pressure oil pipe on hydraulic motor one again.Energy storage device cooperation hydraulic motor one exists
During the raising and lowering of car, efficient recycling and utilization are carried out to generated energy among these, subtracted significantly
The small waste of energy.
Further, the energy supplement device includes pressure sensor and hydraulic motor two；The hydraulic motor two
Oil inlet end is connect with fuel tank, and oil outlet end is connect with the branch two of high-pressure oil pipe two, and transmission shaft end connect transmission machinery with motor
