Definitions

  • the invention relates to a slide closure for a vessel containing molten metal, wherein the slide closure has a slider housing, a slide unit guided longitudinally therein, with a slide rod, a holder on the slider housing as well as a linear actuator which can be fastened in this holder with a drive rod which can be coupled to the slide rod, wherein the linear actuator can be slid into the holder on the slider housing, preferably transverse to its direction of adjustment, and can be removed from same and can be locked in the holder.
  • a known slide closure for a vessel containing molten metal has a slider housing, a slide unit guided longitudinally therein, with a slide rod, a holder on the slider housing as well as a linear actuator which can be inserted into this holder, with a drive rod which can be connected to the slide rod of the slide unit by a coupling.
  • This coupling is developed such that, when in the flange of the linear actuator, it couples the drive rod against the slide unit by shifting the drive rod against the slide unit pushed into a lateral recess of the holder, wherein the coupling has a coupling part at one end on the slide rod and a coupling part at the front end of the drive rod of the linear actuator which couple the drive rod against the slide rod when sliding.
  • the document CN 110394621 discloses a method for repairing a slide closure.
  • a slide plate oil-hydraulic unit is provided for adjusting the slide plate.
  • the linear drive which can be moved by means of a robot, can be pushed laterally into the holder, for this purpose corresponding holding grooves are formed in the holder, into which a retaining ring of the cylinder can be inserted.
  • Connection cables can be connected in which the plug connection is placed on the back in the mounting seat of the holder and on the front of the block below the cylinder, which can be plugged together using a pressure lever after the cylinder has been mounted.
  • This pressure lever is held pivotably by an adjustment drive attached to the clamping device of the robot and is actuated by an external force with this separate adjustment drive, which must be controlled externally.
  • At least one locking means being present, preferably fastened, to each of the linear actuator and to the holder, which locking means are developed to interact such that the linear actuator locks automatically after or during being pushed into the holder, preferably at the end of the pushing-in process.
  • the linear actuator Due to this association, according to the invention, of in each case at least one locking means to the linear actuator and to the holder, by means of which the linear actuator is locked automatically after or during being pushed into the holder, preferably at the end of the pushing-in process, a permanently secure fastening of the linear actuator in the holder results.
  • the automatic locking can prevent movement of the linear actuator against the pushing-in direction and, depending on the design, also prevent a (further) movement of the linear actuator in pushing-in direction, whereby the pushing-in process can be ended by the automatic locking.
  • the one locking means has a shiftable locking element with a front part, where, during locking, this front part engages in a recess of the other locking means such that this locking takes place, wherein the locking element is adjustably housed preferably transverse to the pushing-in direction of the linear actuator.
  • a locking which cannot be loosened during operation is achieved by this development of the interacting locking means.
  • the locking means of the linear actuator comprises a guide housing, this locking element which is shiftable therein, and a spring member, wherein the locking element is shiftable with its front part into a position projecting above the guide housing, by the spring member.
  • the locking means of the holder has a sliding shoe provided with the recess, which shoe is in sliding contact with the front part of the locking element when the linear actuator is being pushed in and/or pushed out.
  • the sliding shoe is designed with a ramp-shaped sliding guide running approximately in pushing-in direction of the linear actuator, for sliding contact with the front part and with this recess.
  • This recess in the sliding shoe is positioned in pushing-in direction with respect to the holder such that the front part clicks into the recess when the linear actuator is against a stop in the holder.
  • the pushing-in process is ended by the stop, wherein the locking also takes place automatically at the end of the pushing-in process. 1 o
  • the sliding shoe in the recess and the front part are reciprocally in contact with a contact surface each, wherein these contact surfaces run at least approximately perpendicular to the pushing-in direction of the linear actuator, with the result that the front part is locked in the sliding shoe.
  • the linear actuator comprising the drive rod and a projecting transverse flange at the front, and this C-shaped guide groove on the rear of the holder for receiving, are known.
  • the guide housing of the locking means is arranged laterally at the transverse flange and the sliding shoe adjacent to this C-shaped guide groove on the rear of the holder. These locking means are thus placed in a region which is approximately protective for them.
  • the guide housing can be arranged adjacent to the guide groove and the sliding shoe laterally at the transverse flange.
  • this actuatable adjusting member is fastened transverse to the locking element of the locking means at the linear actuator, and pushes through a longitudinal opening out of the guide housing preferably away from the linear actuator. By pushing upwards, the locking element with its front part can become disengaged out of the recess in the sliding shoe and the linear actuator released.
  • the invention is also characterized in that these plug elements are placed such that they are inserted automatically after or during being pushed in, preferably at the end of the pushing-in process of the linear actuator into the holder, and that the locking means are locked quasi-automatically. This makes it possible to reduce plugging in the linear actuator to a single action, taking placing manually or via robot, without plug elements needing to be connected additionally by hand.
  • this adjusting member is to be actuated with a locking means for unlocking.
  • the plug elements associated in pairs with the linear actuator and the holder are loosened automatically.
  • the coupling head of the drive rod of the linear actuator can be coupled automatically to the slide rod of the slide unit by an axial adjustment after or during being pushed in, preferably at the end of the pushing-in process of the linear actuator into the holder.
  • a lateral automatic movement away of the coupling head from the slide rod is made possible. Additional advantages result within the meaning of automatic maintenance of the slide closure.
  • FIG. 3 is a longitudinal section through the locking means in locked state with the linear actuator pushed into the holder.
  • the locking means 25 of the linear actuator 20 very advantageously has a guide housing 28 fastened laterally in the transverse flange 22 , a locking element 27 shiftable therein, and a spring member 29 , wherein this locking element 27 with its front part 27 ′ is shiftable by the spring member 29 into a starting position projecting above the guide housing 28 , as illustrated in FIG. 1 when the linear actuator 20 is uncoupled.
