Description
Technical field
It the utility model is related to energy-saving device of elevator field, more particularly to a kind of elevator energy-saving dress based on dynamic equilibrium
Put.
Background technology
With the progress of China's urbanization, the total amount of building energy consumption is rising year by year, shared by energy aggregate consumption
Ratio from the 10% of last century late nineteen seventies, rises to 27.45%, and the building energy consumption of developed country typically constitutes from the world
33% or so of national total energy consumption.Inferred with this, with the quickening of urbanization process and the improvement of people's living standard, China is built
Building energy consumption ratio finally will also rise to 35% or so.So big proportion, architectural energy consumption have become China's economic development
Weakness.
In residential houses class building, the energy consumption of elevator accounts for 5% or so of building total energy consumption, and writes in commercial office
Building, elevator energy consumption account for building energy consumption accounting and are up to 7%, and elevator has become maximum in addition to cooling/heating and lighting electric in building
Energy consumption is paid wages, and is developed, to produce energy saving and environment friendly elevator very urgent.
Tractive driving formula structure is being used with elevator is most at present, traction machine is by the motor connection installed in computer room
The composition such as retarder, brake is closed, traction steel-cable connects carriage and counterweight by directive wheel.It is oriented to when hoisting motor drives
When wheel rotates, steel wire rope and the frictional force between directive wheel grooving drag carriage by steel wire rope and are led with edge in hoistway is focused on
Rail back and forth lifts, and realizes the vertical transport function of elevator.
By the frictional force between hoist ropes and directive wheel come what is realized, this power is referred to as draging for the movement of carriage and counterweight
Gravitation.Run elevator, traction T have to be larger than or equal in hoist ropes compared with large-load force T1 with compared with side crops industry power T2 it
Difference, i.e. T >=T1-T2.As T1=T2, two side load of directive wheel is equal, and frictional force is minimum value between directive wheel and steel wire rope,
It is the optimum condition of elevator operation.
The use occasion of elevator is limited to, the heavy burden of lift car is change, when elevator is run, car load change model
Between being trapped among carriage zero load and being fully loaded with.The balance weight of currently used traction elevator is a fixed value, general according to flat
The coefficient 0.4~0.5 that weighs determines balance weight, and since T1 is variable, T2 is constant, and operationally traction T will necessarily be with for elevator
With T1-T2 difference and change.Using ascending for elevator as row, if elevator cars with full load at this time, in the case that carriage is fully loaded with uplink, traction
System needs to overcome gravity acting, and power needed for motor is very big at this time, and consumed energy is huge；When carriage zero load uplink, T1 is
Minimum value, the potential energy of counterweight release at this time, motor, which need to do work, prevents counterweight from dropping.Due to very big between T2 and T1, not only in counterweight
The potential energy of storage wastes completely, and motor also needs to extra work.
Elevator currently on the market belongs to static balancing system, and car load can change because of passenger carrying capacity, and
Balance weight remains constant and directly acts on motor, thereby results in the gravity unbalance of counterweight and carriage so that fully loaded
Traction system needs to overcome gravity to consume electric energy during uplink, and the potential energy that counterweight stores in unloaded uplink wastes loss again.
Carriage downlink is similar with uplink, and energy dissipation remains unchanged, no longer burdensome.
