Description
Technical field
The invention belongs to gantry crane technical fields, and in particular to a kind of subway gate-type lifting using super capacitor
Machine.
Background technology
In recent years, energy and environmental problem has been to be concerned by more and more people, how environmental protection, energy saving have become
Very important problem.Subway is being built in national 42 cities, the quantity of shield machine about 1000, in conjunction with the characteristics of subway work,
The quantity about 1000 of the vertical means of transport subway work gantry crane of Backup system as shield machine, such gate-type
The characteristics of crane is lifting altitude height, and cart walking range ability is long, and the working level of complete machine is high, especially large vehicle walking, small
Garage is walked and lifting mechanism is during carrying cargo declines, and motor will produce a large amount of energy in braking.
In the prior art, generally use two ways handles these energy:One is add energy consumption in frequency converter DC side
Resistance, directly consumption regeneration energy;Another kind is by regenerated energy feedback power grid.If adding energy consumption resistance, generation is braked again
Raw energy just slatterns, and needs prodigious heat-dissipating space;If feeding back to power grid, although energy, meeting can be saved
Great impact is caused to power grid, i.e., power grid is polluted.It is whole to be powered by the way of cable drum, supply voltage
For 380V the length of leader cable is caused since the cart of such gantry crane, carriage walking distance and lifting altitude are larger
Degree is longer, and cable is easily damaged, and whole security performance is bad.
Invention content
In order to overcome in the prior art subway gantry crane in large vehicle walking, carriage walking and lifting mechanism in carrying
Energy is easily lost, easily forms the technological deficiency impacted to power grid during cargo declines, and the present invention provides a kind of using super
The subway gantry crane of grade capacitance, super capacitor is connected in parallel on service cable line, can be with high-power fast using super capacitor
The characteristic of fast charge and discharge, the kinetic energy that will be stored by the electric energy of resistance loss, and needed in operation process next time,
The operating power consumption of crane is reduced, while ensureing the even running of equipment, reduces the impact to power supply grid.
The present invention is achieved through the following technical solutions above-mentioned purpose, a kind of subway gate-type lifting using super capacitor
Machine, including DC power supply, motor frequency conversion device, AC three-phase motor, super capacitor, DC/DC converters and brake are described straight
The AC conversion of AC three-phase motor is the direct current energy for supplying gantry crane motor frequency conversion device and wanting by galvanic electricity source, simultaneously
Cable drum is eliminated, is directly charged to super capacitor with charger using power distribution cabinet, the super electricity when brake starts
Hold and absorb braking electric energy progress reverse charging, the electric energy of release storage is powered when AC three-phase motor starts.
A kind of above-mentioned subway gantry crane using super capacitor, the super capacitor is using multiple 20F/2.7V's
Monomer super capacitor is cascaded, and the particular number of super capacitor is according to live actual condition and the power storage energy of needs
Power is determined.
A kind of above-mentioned subway gantry crane using super capacitor, the DC/DC converters are connected with super capacitor,
It is connected in parallel on the cable of DC power supply together, the charging and discharging state for controlling super capacitor, control principle is:Work as braking
Device work when namely subway gantry crane lifting mechanism decline or large and small vehicle walking mechanism slow down when, DC power supply
Voltage cable increases, and DC/DC converters, which detect, to charge after voltage is increased to certain value to super capacitor;Work as AC three-phase
When motor works namely when large and small vehicle is in walking or lifting mechanism rising, the voltage cable of DC power supply declines, DC/DC
Converter detects that super capacitor discharges after voltage drops to certain value.
In general, through the invention it is contemplated above technical scheme is compared with the prior art, can reach following has
Beneficial effect:
1, subway gantry crane of the present invention takes full advantage of super capacitor and has extended cycle life and high-power quick charge and discharge
The characteristic of electricity, the kinetic energy that will be stored by the electric energy of resistance loss, and needed in operation process next time reduce
The operating power consumption of crane improves the utilization rate of the energy, has saved economic cost, while ensureing the even running of equipment, subtracts
The impact to power grid is lacked;
2, this kind of gantry crane directly charges to super capacitor using charger on the basis of using super capacitor,
To realize effective storage of electric energy, the power supply mode using cable drum is eliminated, improves the safety of complete machine and steady
It is qualitative.
Description of the drawings
Specific embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings, wherein:
Fig. 1 is a kind of subway gantry crane total system block schematic illustration using super capacitor of the invention;
In figure:1- DC power supplies, 2- motor frequency conversion devices, 3- AC three-phase motors, 4- super capacitors, 5-DC/DC converters, 6-
Brake.
Specific implementation mode
As shown in Figure 1, being a kind of subway gantry crane overall structure diagram using super capacitor, including direct current
