Definitions

  • 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.
  • Such cars are basically known in the art. Such is from the German patent application DE 26 02 655 a method and an on device for inserting or removing a drive spindle of a rolling mill stand known. 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 attached to the Austegearm for transport by means of loops. The device according to this disclosure therefore builds quite high, at least higher than the drive spindles are arranged.
  • 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.
  • 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.
  • 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.
  • 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.e. minimum. the car is as flat as possible. Lifting or lowering even one of the carriers will increase the overall height of the truck.
  • the claimed car is so flat that it can be moved under the drive spindle.
  • the claimed training as a lift truck with a first support means advantageously allows the lifting of the support means directly under the drive spindle, so that they can be stored without the aid of a crane directly on the support means and transported away with the car.
  • the sequence of steps in reverse order First, the drive spindle is transported on the carrier device 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.
  • the carriage has a second carrier device which is integrated into 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.
  • 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.
  • 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.
  • the carriage 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.
  • 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.
  • the lowering of the support means under the neutral position advantageously allows a process of the carriage with the support means under the head of the drive spindle forth; 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.
  • the first and / or second support means are lockable at least in their neutral position, the support means give the
  • 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 for driving the work spindles.
  • the drive spindles are used to drive work rolls in the mill stand 300.
  • the work rolls are typically arranged between the upper and lower support rollers 310a, 310b in the rolling stand. They are, however, in FIG. 1 not shown because they must be removed for the process of the carriage through the mill stand 300 through and are.
  • 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 impellers, 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.
  • the first carrier device 110 is raised as part of the lift truck to the level of the lower or under the 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.
  • FIG. 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.
  • the first carrier device 110 which by means of a first drive means 120, z. B. a hydraulic cylinder, 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.
  • the stroke for only one of the support means is limited due to the toggle lever 116.
  • 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.
  • 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 roller house through the rolling stand.
  • 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.
