Description

Wagen und Verfahren zum Transportieren einer Antriebsspindel für eine Walze eines Walzgerüstes Cart and method for transporting a drive spindle for a roll of a rolling stand
Die Erfindung betrifft einen Wagen zum Transportieren von mindestens einer Antriebsspindel für eine Walze eines Walzgerüstes und ein Verfahren zum Betreiben des Wagens.The invention relates to a carriage for transporting at least one drive spindle for a roll of a roll stand and a method for operating the carriage.
Derartige Wagen sind im Stand der Technik grundsätzlich bekannt. So ist aus der deutschen Offenlegungsschrift DE 26 02 655 ein Verfahren und eine Vor- richtung zum Einsetzen bzw. Entnehmen einer Antriebsspindel eines Walzwerkständers bekannt. Dieses Verfahren zeichnet sich dadurch aus, dass die Spindel nach dem Entfernen der Arbeitswalzen aus dem Walzwerkständer durch einen Schlitten unterstützt durch das Fenster des Walzwerkständers von der Antriebsseite auf die Bedienseite und umgekehrt transportiert wird. An dem Schlitten ist ein Auslegearm schwenkbar angeordnet und die Antriebsspindeln werden für den Transport mit Hilfe von Schlaufen an den Auslegearm angehangen. Die Vorrichtung gemäß dieser Offenlegungsschrift baut deshalb recht hoch, zumindest höher als die Antriebsspindeln angeordnet sind.Such cars are basically known in the art. For example, German published patent application DE 26 02 655 discloses a method and a device for inserting or removing a drive spindle of a rolling mill stand. This method is characterized in that the spindle is transported by the removal of the work rolls from the mill stand by a carriage supported by the window of the mill stand from the drive side to the operating side and vice versa. On the carriage a Auslegearm is pivotally mounted and the drive spindles are hung for transport by means of loops to the extension arm. The device according to this disclosure therefore builds quite high, at least higher than the drive spindles are arranged.
Aus der japanischen Veröffentlichung JP 55 094 714 offenbart einen Transportwagen zum Wechseln von Spindeln für die Arbeitswalzen eines Walzgerüstes. Der Transportwagen ist auf Schienen in Walzrichtung durch den Walzenständer verfahrbar. Der Wagen umfasst ein Transportgerüst, in dem die obere Antriebsspindel von oben und die untere Antriebsspindel von unten gehalten werden. Der Wagen wird ggf. zusammen mit den Spindeln über einen Seilzug durch Walzgerüst hindurch verfahren.From the Japanese publication JP 55 094 714 discloses a trolley for changing spindles for the work rolls of a rolling stand. The trolley is moved on rails in the rolling direction by the roll stand. The cart includes a transport frame in which the upper drive spindle from above and the lower drive spindle are held from below. If necessary, the carriage is moved along with the spindles via a cable pull through the roll stand.
Der Erfindung liegt die Aufgabe zugrunde, einen alternativen Wagen und ein alternatives Verfahren zum Transportieren einer Arbeitsspindel für eine Walze eines Walzgerüstes bereit zu stellen. Diese Aufgabe wird vorrichtungstechnisch durch den Gegenstand des Patentanspruchs 1 gelöst. Demnach ist der Wagen dadurch gekennzeichnet, dass der Wagen als Hubwagen mit einer ersten Trägereinrichtung und einer ersten Antriebseinheit ausgebildet ist, wobei die erste Antriebseinheit zum Anheben oder Absenken der ersten Trägereinrichtung ggf. mit der Antriebsspindel relativ zu einer Neutralstellung dient.The invention has for its object to provide an alternative carriage and an alternative method for transporting a work spindle for a roll of a roll stand ready. This object is achieved by the device technology by the subject of claim 1. Accordingly, the car is characterized in that the carriage is designed as a lift truck with a first support means and a first drive unit, wherein the first drive unit for raising or lowering the first support means possibly with the drive spindle is used relative to a neutral position.
Die Neutralstellung im Sinne der Erfindung bezeichnet diejenige Stellung von erster und/oder zweiter Trägereinrichtung in welcher die Gesamthöhe des Wagens mit den beiden Trägereinrichtung minimal, d.h. der Wagen möglichst flach ist. Ein Anheben oder Absenken von auch nur einer der Trägereinrichtungen führt zu einer Vergrößerung der Gesamthöhe des Wagens.The neutral position in the sense of the invention designates that position of the first and / or second carrier device in which the overall height of the carriage with the two carrier devices is minimal, i. the car is as flat as possible. Lifting or lowering even one of the carriers will increase the overall height of the truck.
Der beanspruchte Wagen ist so flach gebaut, dass er unter die Antriebsspindel verfahrbar ist. Die beanspruchte Ausbildung als Hubwagen mit einer ersten Trä- gereinrichtung ermöglicht vorteilhafterweise das Anheben der Trägereinrichtung direkt unter die Antriebsspindel, so dass diese ohne die Zuhilfenahme eines Krans direkt auf der Trägereinrichtung abgelegt und mit dem Wagen abtransportiert werden kann.The claimed car is so flat that it can be moved under the drive spindle. The claimed construction as a lift truck with a first carrier device advantageously makes it possible to lift the carrier device directly under the drive spindle, so that it can be deposited directly on the carrier device without the aid of a crane and transported away with the carriage.
Für die spätere Montage einer neuen bzw. überholten Antriebsspindel zwischen das Walgerüst und die Antriebseinrichtung für das Walzgerüst, insbesondere ein Kammwalzengetriebe, erfolgt die Abfolge der Schritte in umgekehrter Reihenfolge: Zunächst wird die Antriebsspindel auf der Trägereinrichtung in den Bereich zwischen Walzgerüst und Kammwalzengetriebe transportiert. Dort wird sie mit Hilfe des Hubwagens bzw. der anhebbaren Trägereinrichtung auf die jeweils erforderliche Höhe angehoben, um dort an das Kammwalzengetriebe und an Spindelaufnahmen an dem Walzgerüst angekoppelt zu werden.For the subsequent assembly of a new or reconditioned drive spindle between the mill stand and the drive device for the rolling stand, in particular a pinion gear, the sequence of steps in reverse order: First, the drive spindle is transported on the support means in the area between the mill stand and pinion gear. There it is raised by means of the lift truck or the liftable support means to the respective required height to be coupled there to the pinion gear and spindle mounts to the mill stand.
Gemäß einem ersten Ausführungsbeispiel weist der Wagen eine zweite Trä- gereinrichtung auf, welche in die erste Trägereinrichtung 110 integriert und zusammen mit der ersten Trägereinrichtung 110 gegenüber der Neutralstellung absenkbar und anhebbar ist. Das Vorsehen von zwei - auch relativ zueinander - höhenverstellbaren Trägereinrichtungen hat den Vorteil, dass auch größere Höhen, auf welche die Trägereinrichtungen zur Aufnahme der Arbeitsspindeln angehoben werden müssen, mit Hilfe des Hubwagens erreichbar sind, ohne dass der Hubwagen dabei Einbußen an seiner flachen Bauweise hinnehmen müsste, d. h. mit größerer Mindesthöhe ausgebildet werden müsste.According to a first embodiment, the carriage has a second carrier device, which is integrated in the first carrier device 110 and together with the first carrier device 110 relative to the neutral position can be lowered and raised. The provision of two - also relative to each other - height-adjustable support means has the advantage that even higher heights on which the support means must be raised to accommodate the work spindles, can be reached by means of the lift truck, without the truck taking thereby losses on its flat design would have to, ie would have to be formed with a larger minimum height.
Die zweite Trägereinrichtung mit der zweiten Antriebseinheit ist vorzugsweise von der Höhe her voll in die ursprüngliche Höhe des Hubwagens bzw. in die erste Trägereinrichtung integriert.The second carrier device with the second drive unit is preferably fully integrated into the original height of the lift truck or into the first carrier device from the height.
Die oben genannte Aufgabe wird weiterhin durch ein Verfahren zum Betreiben des Wagens gelöst. Die Vorteile dieses Verfahrens entsprechen im Wesentlichen den oben mit Bezug auf den Wagen genannten Vorteilen.The above object is further achieved by a method for operating the carriage. The advantages of this method essentially correspond to the advantages mentioned above with respect to the car.
Als besonders vorteilhaft ist allerdings zu erwähnen, dass insbesondere die erste Trägereinrichtung mit Hilfe ihres Kniehebel- oder Scherengelenk-Hubsystem nicht nur über die Neutralstellung des Hubwagens hinaus angehoben, sondern auch unter diese Neutralstellung abgesenkt werden kann. In der Neutralstellung oder in angehobener Stellung kann der Wagen auf dem Hüttenflur der Walzen- halle, in der das Walzgerüst steht, verfahren werden. Innerhalb des Walzgerüstes können die Trägereinrichtungen unter die Neutralstellung abgesenkt werden, ohne mit der unteren Stützwalze zu kollidieren, insbesondere nachdem diese zuvor selber abgesenkt wurde. Das Absenken der Trägereinrichtungen unter die Neutralstellung ermöglicht vorteilhafterweise ein Verfahren des Wa- gens mit den Trägereinrichtungen unter dem Kopf der Antriebsspindel her; in Neutralstellung seiner Trägereinrichtungen wäre der Wagen in der Regel nicht unter dem Kopf der Antriebsspindeln her verfahrbar.However, it should be mentioned as particularly advantageous that, in particular, the first carrier device can not only be raised beyond the neutral position of the lift truck with the aid of its toggle lever or scissors joint lifting system, but also can be lowered below this neutral position. In the neutral position or in the raised position, the carriage can be moved on the shed floor of the roller hall in which the rolling stand stands. Within the rolling stand, the support means can be lowered below the neutral position without colliding with the lower support roller, especially after it has been previously lowered itself. Lowering the carrier devices below the neutral position advantageously enables a method of weighing with the carrier devices under the head of the drive spindle; in the neutral position of its support means of the car would not be moved under the head of the drive spindles in the rule.
Vorteilhafterweise sind die erste und / oder zweite Trägereinrichtung zumindest in ihrer Neutralstellung jeweils verriegelbar; die Trägereinrichtungen geben dem Wagen in verriegelter Stellung eine wesentlich größere Stabilität (Verwindungs- steifigkeit) als in nicht-verriegelter Stellung.Advantageously, the first and / or second support means are lockable at least in their neutral position; the carrier devices give the Carriage in locked position a much greater stability (torsional stiffness) than in unlocked position.
Weitere vorteilhafte Ausgestaltungen des Wagens und des Verfahrens zu seinem Betrieb sind Gegenstand der Unteransprüche.Further advantageous embodiments of the carriage and the method for its operation are the subject of the dependent claims.

Die Erfindung wird nachfolgend unter Bezugnahme auf die genannten Figuren in Form von Ausführungsbeispielen detailliert beschrieben. In allen Figuren sind gleiche technische Elemente mit gleichen Bezugszeichen bezeichnet.The invention will be described in detail below with reference to the said figures in the form of embodiments. In all figures, the same technical elements are designated by the same reference numerals.
Figur 1 zeigt zwei Antriebsspindeln 200, die zwischen einem Walzgerüst 300 und einer Antriebseinrichtung 400, insbesondere einem Kammwalzengetriebe zum Antreiben der Arbeitsspindeln angeordnet sind. Die Antriebsspindeln dienen zum Antreiben von Arbeitswalzen in dem Walzgerüst 300. Die Arbeitswal- zen sind typischerweise zwischen der oberen und unteren Stützwalze 310a, 310b im Walzgerüst angeordnet. Sie sind jedoch in Figur 1 nicht gezeigt, weil sie für das Verfahren des Wagens durch das Walzgerüst 300 hindurch ausgebaut sein müssen und sind. Es ist weiterhin der erfindungsgemäße Wagen 100 zum Transport der Antriebsspindeln zu erkennen. Der Wagen weist eine Lauf- einheit 105, hier beispielsweise Laufräder auf, um den Wagen - ggf. mit den Antriebsspindeln - von der Bedienseite BS des Walzgerüstes 300 durch das Walzgerüst hindurch auf die Antriebsseite AS oder umgekehrt zu verfahren. Der Wagen ist dabei grundsätzlich so flach gebaut, dass er unter die Antriebsspindeln 200 und insbesondere deren verbreiterten Köpfe 210 verfahrbar ist.FIG. 1 shows two drive spindles 200 which are arranged between a rolling stand 300 and a drive device 400, in particular a pinion gear drive for driving the work spindles. The drive spindles are used to drive work rolls in the mill stand 300. The labor Cylinders are typically arranged between the upper and lower support rollers 310a, 310b in the rolling stand. However, they are not shown in Figure 1, because they must be removed for the process of the carriage through the mill stand 300 through and are. Furthermore, the carriage 100 according to the invention can be seen for transporting the drive spindles. The carriage has a running unit 105, here for example running wheels, in order to move the carriage - possibly with the drive spindles - from the operating side BS of the rolling stand 300 through the rolling stand to the drive side AS or vice versa. The car is basically built so flat that it is movable under the drive spindles 200 and in particular their widened heads 210.
In Figur 1 ist die erste Trägereinrichtung 110 als Bestandteil des Hubwagens auf die Höhe der unteren bzw. unter die untere Antriebsspindel 200 angehoben. In dieser Position kann die Antriebsspindel vorteilhafterweise ohne die Mithilfe eines Kranes auf der ersten Trägereinrichtung abgelegt werden.In FIG. 1, the first carrier device 110 as part of the lift truck is raised to the level of the lower or lower drive spindle 200. In this position, the drive spindle can be advantageously stored without the aid of a crane on the first support means.
Figur 2 zeigt den konstruktiven Aufbau des erfindungsgemäßen Wagens 100 im Detail mit der ersten und einer zweiten Trägereinrichtung 110, 112 jeweils in Neutralstellung. Es ist insbesondere die erste Trägereinrichtung 110 zu erkennen, die mit Hilfe einer ersten Antriebseinrichtung 120, z. B. einem Hydraulikzy- linder, und einer ersten Hubeinrichtung 116, zum Beispiel einer Kniehebel- Hubeinrichtung, gegenüber der Neutralstellung angehoben und abgesenkt werden kann. Der Wagen kann entweder nur eine oder beide Trägereinrichtung aufweisen, je nach erforderlicher Gesamthubhöhe.Figure 2 shows the structural design of the carriage 100 according to the invention in detail with the first and a second support means 110, 112 each in the neutral position. In particular, it can be seen the first carrier device 110, which by means of a first drive means 120, z. B. a Hydraulikzy-, and a first lifting device 116, for example, a toggle lever lifting device, relative to the neutral position can be raised and lowered. The cart may either have only one or both support means, depending on the required total lift height.
Der Hubweg für nur eine der Trägereinrichtungen ist aufgrund der Kniehebel- Hubeinrichtung 116 begrenzt. Um darüber hinausgehende größere Hübe erreichen zu können, ist erfindungsgemäß die zweite Trägereinrichtung 112 in die erste Trägereinrichtung 110 integriert, wobei die zweite Trägereinrichtung ihrerseits mit Hilfe einer zweiten Antriebseinheit 114, z. B. in Form eines Hydraulik- Zylinders und einer zweiten Hubeinrichtung 116, zum Beispiel eines zweiten Kniehebelgelenkes, über die erste Trägereinrichtung hinaus angehoben oder abgesenkt werden kann.The stroke for only one of the support means is limited due to the toggle lift 116. In order to be able to achieve larger strokes beyond this, according to the invention the second carrier device 112 is integrated into the first carrier device 110, the second carrier device in turn being driven by means of a second drive unit 114, e.g. Example in the form of a hydraulic cylinder and a second lifting device 116, for example a second Toggle joint, can be raised or lowered beyond the first support means.
Der Wagen verfügt vorzugsweise über eine eigene dritte Antriebseinheit 140 zum eigenständigen Verfahren des Wagens. Alternativ kann er auch mit Hilfe von externen Antrieben, z. B. einer Walzenwechsellokomotive, die über Seilzüge an den Wagen angekoppelt sind, verfahren werden. Die Laufeinheit 105 des Wagens kann in Form von Laufrädern oder in Form von Gleitkufen ausgebildet sein, jeweils um den Wagen auf Schienen, welche auf dem Boden einer Walzenhalle durch das Walzgerüst hindurch verlegt sind, zu verfahren.The carriage preferably has its own third drive unit 140 for autonomous movement of the carriage. Alternatively, it can also with the help of external drives, eg. B. a roll changing locomotive, which are coupled via cables to the car to be moved. The running unit 105 of the carriage may be in the form of running wheels or in the form of skids, each for traversing the carriage on rails laid on the floor of a rolling hall through the rolling stand.
Der Wagen wird erfindungsgemäß wie folgt betrieben:The car is operated according to the invention as follows:
- Verfahren des Wagens 100 unter die Antriebsspindel 200 eines Walzgerüstes 300;Moving the carriage 100 under the drive spindle 200 of a rolling stand 300;
- Anheben einer ersten und/oder zweiten Trägereinrichtung 112, 110 des Wa- gens unter die Antriebsspindel 200;Lifting a first and / or second carrier device 112, 110 of the vehicle under the drive spindle 200;
- Aufnehmen der Antriebsspindel;- picking up the drive spindle;
- erforderlichenfalls Absenken der ersten und/oder zweiten Trägereinrichtung mit der Antriebsspindel z. B. bis auf die Neutralstellung; und- If necessary, lowering the first and / or second support means with the drive spindle z. B. except for the neutral position; and
- Wegverfahren des Wagens mit der Antriebsspindel 200.- Way of the carriage with the drive spindle 200.
Das Verfahren des Wagens unter die Antriebsspindel 200 und das Wegverfahren des Wagens können durch das Walzgerüst 300 hindurch oder quer zu den Arbeitsspindeln erfolgen.The movement of the carriage under the drive spindle 200 and the path of the carriage can be done through the mill 300 or across the work spindles.
Wenn das Hinfahren des Wagens zu den Antriebsspindeln 200 durch das Walzgerüst 300 hindurch erfolgt, dann umfasst das Hineinfahren folgende Schritte:When the carriage travels to the drive spindles 200 through the rolling stand 300, then the retraction includes the following steps:
- Der Wagen mit der ersten und ggf. der zweiten Trägereinrichtung in jeweils neutraler oder angehobener Stellung wird in das Walzgerüst mit ausgebauten- The car with the first and possibly the second support means in each neutral or raised position is removed in the rolling stand with
Arbeitswalzen eingefahren. Die neutrale oder angehobene Stellung der Trä- gereinrichtungen ist erforderlich, damit die Trägereinrichtung beim Hineinfahren nicht mit dem Hüttenflur kollidiert; siehe Figur 3.Working rolls retracted. The neutral or raised position of the carrier gearing is required so that the carrier does not collide with the hut floor when entering; see FIG. 3.
Die erste und ggf. zweite Trägereinrichtung wird vor Erreichen des Kopfes 210 der Antriebsspindel 200 innerhalb des Walzgerüstes 300 unter die Neutralstellung und damit unter den Kopf abgesenkt, um unter dem Kopf her verfahren werden zu können; siehe Figur 4 und 5.The first and possibly second carrier device is lowered before reaching the head 210 of the drive spindle 200 within the rolling stand 300 under the neutral position and thus under the head to be able to be moved under the head; see FIGS. 4 and 5.
Nach Passieren des Kopfes werden die Trägereinrichtungen soweit wie erforderlich - typischerweise über die Neutralstellung hinaus - unter die Antriebsspindel angehoben, um die Antriebsspindel zusammen mit ihrem Kopf aufzunehmen.After passing the head, the carrier devices are raised as far as necessary, typically beyond the neutral position, under the drive spindle to receive the drive spindle together with its head.
Anschließend erfolgt das Wegverfahren des Wagens mit der Antriebsspindel, wobei aber die erste und zweite Trägereinrichtung nicht unter die Neutralstellung abgesenkt sind, um nicht mit dem Hüttenflur zu kollidieren. Subsequently, the path of the carriage is carried out with the drive spindle, but the first and second support means are not lowered below the neutral position, so as not to collide with the hut floor.
