Definitions
- the invention relates to a slide closure for a vessel containing molten metal according to the preamble of claim 1.
- a generic sliding lock is in the publication EP 0 875 320 B1 disclosed, which serves to regulate the outflow from the vessel during pouring by being opened, closed or controlled in a controlled manner by moving the slide unit by means of a linear drive via the openings of the mutually braced refractory closure plates. Therefore, the push rod of the slide unit must first be coupled with the drive rod of the linear drive. This takes place automatically with the aid of the linear drive, in that its drive rod is pushed against the push rod of the slide unit. After pouring, the linear drive is usually pulled out of the holder that accommodates it and remains on the pouring platform, while the emptied vessel is brought to a pan or the like to wait. For easier assembly in the holder, the linear drive is pushed laterally into a guide groove in the latter, in which it is largely held in a form-fitting manner during the casting process.
- a displacement device for displacing a slide closure in which a piston, a main rod connected to it and a coupling head provided at the other end thereof are fastened in a cylinder.
- Another piston on the main rod is provided with a sleeve part protruding from the cylinder, by means of which the cylinder can be pressed and thus held in a housing.
- a third coupling rod is provided within the main rod, by means of which the coupling means in the coupling head can be activated or deactivated.
- the invention is based on the object of improving a sliding closure of the type mentioned at the outset in such a way that it enables an automated assembly or disassembly of its linear drive before and after casting.
- the linear drive is formed by a hydraulic cylinder which is provided with a main piston that drives the drive rod and an additional piston that can be moved independently of this for actuating the locking device.
- the invention provides that the additional piston is provided with a locking head guided on the drive rod, which, when the additional piston is acted on, moves out of the interior of the hydraulic cylinder in the locking direction at the front and enters a correspondingly shaped recess in the holder with a positive and / or non-positive fit, it is removed from the recess in the holder when the additional piston is acted upon in the unlocking direction and moves back into the interior of the hydraulic cylinder.
- a particularly suitable linear drive according to the invention is characterized in that it is designed to be multifunctional by locking the linear drive in its holder, coupling its drive rod to the push rod of the slide unit and moving the slide unit during the pouring process to control the flow rate of the Melted metal accomplished from the vessel.
- the hydraulic cylinder in such a way that it is provided between the two pistons with a partition serving as a stop for the additional piston with an opening for the drive rod to pass freely through.
- FIGS. 1 to 3 show a holder 5 of an indicated slide housing 1 as well as a linear drive 6 which can be accommodated in this for a slide lock, which has the slide housing 1 and a slide unit guided longitudinally in this via a push rod 2.
- the linear drive 6 is usually only installed in the holder of the slide closure after the vessel, which is provided in particular as a pan, has been placed on the casting platform of a continuous casting plant filled with molten metal. This is advantageously done with a robot manipulator, not shown in detail, which can be coupled to a coupling piece 10 ′ of the linear drive 6 and thereby pushes the linear drive 6 with its flange 20 laterally into a recess in the holder 5.
- the sliding lock is equipped according to the invention with a locking device 7 which can be actuated with the linear drive 6 and interacts with the holder 5.
- This locking device 7 has a preferably cylindrical locking head 8 which, in the locked state, is positively inserted into a likewise cylindrical recess 9 in the holder 5. In contrast, this locking head 8 can be removed from the recess 9 in the unlocking direction when the additional piston 12 of the locking device 7 is acted upon.
- the linear drive 6 operating according to the invention comprises a hydraulic cylinder 10 with two independently movable pistons 11 and 12, the main piston 11 serving to actuate the drive rod 4, while the additional piston 12 is used to actuate the locking device 7.
- the locking head 8 is guided tightly on the drive rod 4 and can be displaced relative to it by the additional piston 12.
- a partition 13 serving as a stop for the additional piston 12 is arranged in the hydraulic cylinder 10 and is provided with a central opening 14 through which the drive rod 4 protrudes.
- This push rod 2 can be connected to the drive rod 4 of the linear drive 6 via a coupling 3, the coupling 3 automatically coupling by moving the drive rod 4 of the linear drive against the push rod 2 of the slide unit. It is provided with a coupling part at the end of the push rod 2 and a coupling part at the front end of the drive rod 4 of the linear drive 6, which couple when the drive rod 4 is moved, while this coupling 3 is transverse to the direction of displacement of the drive rod when the linear drive 6 is removed from the holder 5 4 automatically decoupled.
- the automatically operating coupling 3 is designed as a claw coupling, the spring-loaded claw elements 16 of which are spread outward when the drive rod 4 is advanced over the coupling head 17 of the push rod 2 until they snap in due to the spring force and positively grip the coupling head 17 of the push rod 2, as in Fig. 3 shown.
- the also automatic disengagement takes place by laterally pulling out the linear drive 6, in that the two claw elements 16 slide in the snapped-in state transversely to the longitudinal extension of the push rod 2 on the coupling head 17 until they are laterally released from it.
- Figure 4b shows the hydraulic cylinder 10 being installed in the holder 5 of the housing with retracted piston 12 and locking head 8.
- the hydraulic cylinder 10 is locked with the bracket 5 when the middle chamber 15b is acted upon and the drive rod 4 is coupled to the push rod 2 of the slide unit when the rear chamber 15a facing away from this drive rod is acted upon ( Fig.4d ).
- the acted upon chamber 15b is indicated by the arrow 15 'in white or the other two arrows 15, 15 ′′ in black for chambers 15a, 15c that are not acted upon, as in FIG Figure 4c can be seen.
- the locking head 8 could be pressed into the recess 9 of the holder 5 in such a way that a force fit between it and the holder 5 would be achieved.
- Fig. 4f shows the unlocking of the locking head 8, in which the front chamber 15c in the hydraulic cylinder 10 is subjected to the medium pressure, as shown by the white arrow 15 ".
- the linear drive 6 can be pulled out laterally, in which the coupling 3 is released automatically.
- the locking device 7 according to the invention is suitable both for so-called two-plate slides with a fixed and a movable slide plate and for so-called three-plate slides with two fixed slide plates and a slide plate that can be displaced between them.
- the coupling could vice versa with the claw elements on the push rod of the slide unit, while the other coupling part with the flange-like design could be provided on the drive rod of the linear drive.
