Abstract
Description
Die Erfindung betrifft einen dieselelektrischen Portalhubstapler (Straddle Carrier) entsprechend dem ersten Patentanspruch.The The invention relates to a diesel-electric straddle carrier (Straddle Carrier) according to the first claim.
Die Erfindung ist anwendbar für Portalhubstapler, sogenannte Straddle Carrier.The Invention is applicable to Straddle carrier, so-called straddle carrier.
Portalhubstapler sind weltweit zu Tausenden in Seehäfen und Containerterminals zum Transportieren und Stapeln von Containern eingesetzt. So sind z. B. in Hafenstädten wie Hamburg oder Bremerhaven tagtäglich Hunderte solcher dieselgetriebenen Fahrzeuge im Einsatz, die entsprechende Mengen Kraftstoff verbrauchen und mit ihren Abgasen die (oft städtische) Umwelt belasten. Eine Technik, die den Energieverbrauch und Schadstoffausstoß dieser Fahrzeuge bis auf ein absolut notwendiges Mindestmaß reduziert, ist daher sowohl ökonomisch als auch ökologisch sinnvoll.straddle There are thousands of seaports and container terminals worldwide used for transporting and stacking containers. So are z. B. in port cities like Hamburg or Bremerhaven every day hundreds of such diesel-powered vehicles in use, consume the appropriate amounts of fuel and with their exhaust gases the (often urban) Burden the environment. A technology that reduces the energy consumption and pollutant emissions of these vehicles reduced to an absolutely necessary minimum, is therefore both economical as well as ecological meaningful.
Dieselelektrische Antriebssysteme für solche Straddle Carrier sind bekannt. Im allgemeinen bestehen sie aus einem Dieselgeneratorsatz zur Erzeugung elektrischer Energie, einem Gleichspannungszwischenkreis, und mehreren, daran angeschlossenen regelbaren Wechselrichtern zur Drehstromspeisung von Fahr- und Hubwerksmotoren. Diese bisher bekannten Antriebssysteme haben jedoch den Nachteil, daß die elektrische Energie, welche beim generatorischen Bremsen der Fahr- und Hubmotoren (z. B. beim Absenken der Last, oder beim elektrischen Bremsen des Fahrwerks) in den Zwischenkreis zurückgespeist wird, mit Bremswiderständen vernichtet wird und so für immer verloren geht.diesel Electric Drive systems for Such straddle carriers are known. In general, they exist from a diesel generator set for generating electrical energy, a DC intermediate circuit, and several connected thereto Adjustable inverters for three-phase current supply of traction and hoist motors. However, these previously known drive systems have the disadvantage that the electrical energy which is generated during regenerative braking of the vehicle and lifting motors (eg when lowering the load, or during electric braking of the chassis) is fed back into the DC link, is destroyed with braking resistors and so for always gets lost.
Für andere
Fahrzeuge sind daher schon lange Antriebssysteme entwickelt worden,
welche die Bremsenergie in einem elektrischen Energiespeicher zwischenspeichern
und so beim Beschleunigen wieder nutzbar machen. Eine Vielzahl von
derartigen Patenten ist bekannt. Hier sei als Beispiel nur
Aber auch wartungsfreie, langlebige und leichte Energiespeicher mit hoher Leistungsdichte sind bekannt. Es sind Doppelschichtkondensatoren mit sehr hohen Kapazitäten, die unter den Namen „Ultra-Kondensatoren" oder „Ultracaps" inzwischen zu halbwegs akzeptablen Preisen auf dem Markt erhältlich sind. Erste Versuche mit einem dieselelektrischen Omnibus, der mit Ultracaps als Bremsenergiespeicher ausgerüstet war, haben erhebliche Kraftstoffeinsparungen (10 – 15 %) und Emissionsreduktionen im Stadtverkehr ergeben.But Also maintenance-free, durable and lightweight energy storage with high Power density is known. There are double-layer capacitors with very high capacities, under the name of "Ultra Capacitors" or "Ultracaps" meanwhile too halfway acceptable prices are available in the market. First try with a diesel-electric bus, with ultracaps as brake energy storage equipped was, have significant fuel savings (10 - 15%) and emission reductions in city traffic.
Allerdings läßt sich diese Technik, die für Omnibusse oder andere Hybridfahrzeuge entwickelt wurde, nicht ohne weiteres direkt auf Portalhubstapler übertragen: Jene Fahrzeuge haben nur Fahrantriebe, ein Straddle Carrier hat jedoch zusätzlich ein Hubwerk und weitere Hilfsantriebe. Daher muß für die Entwicklung eines kraftstoffsparenden Antriebssystems für Straddle Carrier vor allem die Energieflußsteuerung derart weiterentwickelt werden, daß nicht nur die kinetische Energie des Fahrzeuges, sondern auch die potentielle Energie der gehobenen Last bei der Lade- und Entladestrategie für den Ultracap-Energiespeicher mit berücksichtigt wird. Weiterhin ist der Einbauplatz auf Portalstaplern sehr begrenzt. Zusätzliche Komponenten sind auf ihm kaum noch unterzubringen. Dies gilt vor allem für den bei Omnibussen und anderen Anwendungen eingesetzten DC/DC-Wandler (elektronischer Hoch/Tiefsetzsteller), der für das gesteuerte laden/entladen des Speichers gebraucht wird, um dessen Kapazität optimal zu nutzen.Indeed let yourself this technique for buses or other hybrid vehicles has been developed, not readily Transfer directly to straddle carrier: Those vehicles have only travel drives, a straddle carrier has however, in addition a hoist and other auxiliary drives. Therefore, for the development of a fuel-efficient Drive system for Straddle carriers in particular, the energy flow control developed so will not do that only the kinetic energy of the vehicle, but also the potential Energy of the upper load in the charging and discharging strategy for the Ultracap energy storage taken into account becomes. Furthermore, the slot on portal trucks is very limited. additional Components are hardly to be accommodated on it. This is true everything for the DC / DC converters used in buses and other applications (electronic up / down converter), which for the controlled charge / discharge the memory is needed to optimally use its capacity.
Es ist daher die Aufgabe der Erfindung, die oben angegebenen Nachteile des Standes der Technik zu beseitigen und ein kraftstoffsparendes und umweltfreundliches Antriebssystem speziell für die Erfordernisse von dieselelektrischen Straddle Carriern aufzuzeigen.It Therefore, the object of the invention, the disadvantages mentioned above to eliminate the prior art and a fuel-efficient and environmentally friendly drive system especially for the requirements of diesel-electric Show straddle carriers.
Diese Aufgabe wird von einem Portalhubstapler nach den Merkmalen des ersten Patentanspruches gelöst. Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung wieder.These Task is by a straddle carrier truck according to the characteristics of the first Claim solved. under claims give advantageous embodiments of the invention again.
Die erfindungsgemäße Lösung sieht einen Portalhubstapler mit dieselelektrischem Antriebssystem, bestehend aus einem Dieselmotor vor, der einen Generator antreibt, welcher seine erzeugte elektrische Energie über einen Gleichrichter in einen Gleichspannungszwischenkreis einspeist, an welchem wiederum Wechselrichter zur Speisung der Fahr- und Hubmotoren mit Drehstrom angeschlossen sind. Erfindungsgemäß ist am Gleichspannungszwischenkreis ein elektrischer Energiespeicher aus zusammengeschalteteten Ultrakondensatoren über einen elektronischen Schalter mit einer antiparallel geschalteter Diode angeschlossen. Er steuert über eine Steuereinrichtung mit diesem elektronischen Schalter den Ladezustand des Speichers so, daß die im elektrischen Bremsbetrieb von den Fahr- und Hubmotoren generatorisch zurückgespeiste Energie im Speicher zwischengespeichert wird und bei anschließendem motorischen Betrieb über die Diode wieder in den Zwischenkreis und damit an die Fahr- Hub- und Hilfsantriebe abgegeben wird.The solution according to the invention provides a straddle lift truck with a diesel-electric drive system consisting of a diesel engine which drives a generator which feeds its generated electrical energy via a rectifier into a DC intermediate circuit to which in turn inverters for feeding the traction and lifting motors with three-phase current are connected. According to the invention, an electrical energy store composed of interconnected ultracapacitors via an electronic switch with an antiparallel connected diode is connected to the DC voltage intermediate circuit. He controls via a control device with this electronic Switch the state of charge of the memory so that the regenerative energy fed back in the electric braking operation of the drive and lifting motors in the memory and is delivered in subsequent motor operation via the diode back into the DC bus and thus to the driving hub and auxiliary drives.
Vorteilhaft ist es, durch eine elektronische Steuerung die Generatorspannung durch Verstellen der Dieseldrehzahl an den momentanen Spannungsbedarf der Antriebsmotore anzupassen und damit den Energiespeicher besser auszunutzen.Advantageous is it, by an electronic control the generator voltage by adjusting the diesel speed to the current voltage requirement adapt the drive motors and thus the energy storage better exploit.
Weiterhin ist es vorteilhaft, wenn der elektronische Schalter der in handelsüblichen Umrichtern schon vorhanden Bremschopper oder sonst ein handelsüblicher Bremschopper ist.Farther It is advantageous if the electronic switch of commercially available Converters already present brake chopper or otherwise a commercial one Bremschopper is.
Die Steuereinrichtungen sollte eine speicherprogrammierbare Steuerung oder ein Rechner sein, in welchem eine speziell zum Zwecke der Ladezustandsregelung des Energiespeichers und zur Drehzahlverstellung des Dieselmotors entwickelte Software implementiert ist. Weiterhin ist es vorteilhaft, wenn die Steuereinrichtung die ohnehin zum Bremschopper mitgelieferte Steuereinrichtung ist, welche bei Erreichen der maximalen Zwischenkreisspannung den Bremschopper einschaltet und damit den Energiespeicher lädt.The Control devices should have a programmable logic controller or a computer in which one especially for the purpose of state of charge control the energy storage and speed adjustment of the diesel engine developed software is implemented. Furthermore, it is advantageous if the control device already supplied to the brake chopper Control device is which, upon reaching the maximum DC link voltage turns on the brake chopper and thus loads the energy storage.
Um den Schalter nicht mit kurzzeitigen Stromspitzen zu überlasten ist es vorteilhaft zwischen dem elektronischen Schalter und dem Energiespeicher eine Drossel zu schalten.Around Do not overload the switch with short-term current peaks it is advantageous between the electronic switch and the Energy storage to turn on a choke.
