Definitions
- the invention relates to a method and apparatus for the separate installation and removal of a hydraulic piston-cylinder unit used as Oszillationsantrieb in the oscillation change unit designed as a frame oscillation oscillation of an oscillating movable continuous casting mold.
- DE 44 44 941 C3 proposes to dispense with the water tank and to support the mold side walls directly on the lifting table.
- the oscillation drive With a required change of the oscillation drive, however, it is necessary that the entire oscillation change device must first be removed in order to gain access to the oscillation drive.
- the oscillation drive is integrated into the oscillation device so that when changing the Oszillationsantriebs the entire oscillation change unit initially removed or another assembly step must be carried out beforehand to get access to the oscillation drive , This means time-consuming repairs and long plant shutdowns.
- the object is achieved with the characterizing features of the method in that the installation and removal without previous other assembly steps is performed directly by a specially provided in the oscillation change unit receiving opening, the piston-cylinder unit when installed by means of a movable Montagevorrich- device brought with carrying function to the oscillation change unit, inserted horizontally into the receiving opening and fastened there to a bridge and removed during their removal in the opposite way from the receiving opening and removed from the oscillation change unit.
- the characteristic features of the device provide that in the frame of the oscillation, a special receiving device for the piston-cylinder unit is integrated, which is accessible from the outside by a arranged on one of the broad sides of the oscillation change unit receiving opening.
- the mounting device with a crane or with an auxiliary hoist, such as a forklift, designed to be movable and the design of the piston-cylinder unit is adapted to the mounting device and the recording and coupling in the oscillation change unit.
- the piston-cylinder unit is attached to the underside of a cylinder plate, the piston rod inserted through a through opening in the cylinder plate and protrudes from the top of this.
- the mounting device consists of a supported support plate which has fork-shaped projecting arbors at its front end, which can be inserted into two lateral insertion openings of the cylinder plate for producing a frictional connection with the piston-cylinder unit.
- At the top of the support plate are crane hook Loops which enable transport of the support plate with the "impaled" piston-cylinder unit by means of a crane or a similar lifting tool.To stabilize during transport, the support plate is loaded at its rear end below the crane hook loop there with a draw weight.
- the mounting device is a guide element formed from two interconnected legs with lateral guide rails, which is pivotable about a centrally arranged radial axis of rotation.
- this is formed with a transport bolt whose length corresponds to the inner spacing of the legs of the guide element and which is inserted with its ends in the lateral guide rails of the legs.
- the transport bolt is arranged so that the center of gravity of the piston-cylinder unit is located below the transport bolt and aligns the piston-cylinder unit always perpendicular to a pivoting of the guide member about its axis of rotation by rotation about the transport bolt. So that the transport bolt and thus the piston-cylinder unit can not slide out of the lateral guide rails with vertical transport of the guide element, is located below the axis of rotation of the guide element on each leg a through opening for a push-through retaining pin to prevent this "slipping".
- This mounting device can also be transported by a crane or a similar lifting tool, with the ends of the axis of rotation led out laterally from the guide element and a crane hook loop arranged at the rear end of the guide element being used for the suspension.
- the guide element When the guide element is transported vertically, it only hangs on the crane eye eyelet; only when it is pivoted into the horizontal position of the guide element required for installation and removal do the suspension points become visible used at the axis of rotation.
- An attached to the crane hook eye draw weight or a manual pull rope then ensures a stable horizontal position.
- a flange connection is present, for example in the form of a quick coupling.
- Fig. 1 is a Oszillations batü with one of a supported
- Support plate formed mounting device in perspective view
- FIG. 4 is a front view of a second mounting device in vertical position
- FIG. 5 is a side view of the mounting device of FIG. 4,
- FIG. 6 shows an oscillation change unit with the mounting device of Fig. 4 in a horizontal position
- Fig. 7 shows a possible arrangement of the receiving opening on the oscillation change unit.
- FIG. 1 shows a perspective view of an oscillatory change unit 1 with a lifting table 2 and a front connection plate 3 with the receiving opening 4 for the piston-cylinder unit 5.
- Suspended from crane ropes 30 is located at a distance from the oscillatory change unit 1 at the level of its receiving opening 4 from a supported on its underside support plate 14 mounting device for crane attachment are at the top of the support plate 14 three crane hook loops 11, 12, 12 'and for stabilization during the crane transport below the crane hook loop 11 at the rear end 16 of the support plate 14, a draw weight 18.
- the draw weight 18 can be reinforced by a manually operated towing rope or completely replaced.
- piston-cylinder unit 5 is formed with an additional cylinder plate 6. Below the cylinder plate 6, the hydraulic cylinder 7 is arranged, the piston rod 8 is performed by the cylinder plate 6. In the cylinder plate 6 are lateral insertion openings 9 (see Fig. 3), in which the arranged at the front end of the support plate 14 Aufsteckdorne 13 are inserted for transporting the piston-cylinder unit 5.
- the receiving opening 4 contains an inwardly projecting web 4 'onto which the cylinder plate 6 is lowered or raised during assembly and fastened thereto.
- FIG. 3 shows, in an enlarged partial section, the cylinder plate 6 arranged above the hydraulic cylinder 7 for transport and for lowering onto the inwardly projecting web 4 'of the receiving opening 4 on the piston-cylinder unit 5. It contains the lateral plug-in openings 9 serving to receive the plug-on mandrels 13, vertical through-openings 9 'for fastening within the receiving opening 4 and a centrally arranged passage opening for the passage of the piston rod 8.
- FIGS. 4 and 5 show, in a front view (FIG. 4) and a side view (FIG. 5), the fork-shaped guide element 21 consisting of two legs 22 connected to each other by transverse beams 29, 29 '.
- the front ends of the legs 22 can be tapered in steps be.
- the guide element 21 is suspended in a vertical position on crane ropes 30, wherein the suspension points used are a crane hook eye 26 arranged at the rear end 27 of the guide element 21 and the extended ends 23 'of the rotation axis 23.
- the transport pin 24 is connected below the cylinder plate 6 with the piston-cylinder unit 5, whereby it is supported by the transport pin 24. Since the transport pin 24 is arranged above the center of gravity of the piston-cylinder unit 5, the piston-cylinder unit 5 is oriented by rotation about the transport pin 24 automatically perpendicular from, why it is aligned parallel to this in the illustrated vertical position of the guide member 21.
- FIG. 6 in the same way as in FIG. 1, the mounting device 20 is shown in a mounting position immediately before the oscillation change unit 1.
- the guide element 21 of the mounting device 20 of FIGS. 4 and 5 has been pivoted to the horizontal position required for carrying out the assembly by means of the tension cable 18 about the axis of rotation 23. Due to the existing possibility that the piston-cylinder unit 5 can rotate about the transport pin 24, the piston-cylinder unit 5 retains its vertical position of FIGS. 4 and 5 during the pivoting of the guide element 21.
- the piston-cylinder unit 5 is now in the same height with the receiving opening 4 of the oscillation change unit 1, so that by lateral movement of the mounting device 20, the piston-cylinder unit 5 can be introduced into this receiving opening 4.
- FIG. 7 shows an enlarged view of a possible receiving opening 4 arranged in the oscillatory change unit 1 of a frame oscillation.
- a web 4 ' for example, the illustrated in Fig. 1 piston-cylinder unit 5 is lowered with its cylinder plate 6 with the mounting device 10 of FIG. 1 for installation and lifted for removal again.
- the mounting device is first moved to the receiving opening 4 and then inserted horizontally in the direction of arrow 19 with its front end into the receiving opening 4.
