Definitions

  • the present invention relates to the production of a disconnectable electrical connection between two parts of the same installation.
  • This invention finds application in the event that one of the parts to be connected, which is typically fixed but may have some mobility and which will be called hereinafter “mobile assembly”, performs, during the operation of the installation, limited displacements compared to the other, which is typically fixed but may have some mobility and which will be called hereinafter “fixed set” or “set upstream ".
  • Such displacements are typically alternative and will be called hereafter “functional displacements”.
  • In this electrical connection is established before each period and it must be maintained during this period despite functional displacements. She permits for example to electrically power the mobile assembly to from the fixed set.
  • the disconnectable electrical connection of an assembly mobile to a fixed assembly can be achieved by the cooperation of two complementary connection blocks one consisting of male plugs the other of female plugs.
  • two complementary connection blocks one consisting of male plugs the other of female plugs.
  • two such blocks connected so permanent to the fixed assembly and to the mobile assembly will respectively designated below as being an “upstream block” and a “downstream block”.
  • a first known connection system is used fluently.
  • the downstream block is fixed during the operation of the installation and it is connected to electrical terminals of the mobile assembly by conductors flexible or at least deformable whose deformations allow functional movement. This can be summary by stating that the downstream block is connected by conductors with functional deformations.
  • the two ends of each of the conductors that make its permanent connection to fixed set terminals are fixed one with respect to the other so that these conductors are, if not rigid, less free from deformations imposed by displacements functional.
  • the mobile assembly In certain situations encountered in manufacturing industries the mobile assembly must be able be disconnected and transported remotely between two periods of operation, for example to be replaced by a equivalent new set, or to be reinstalled after maintenance operations such as repair or renovation.
  • the amplitude of the displacements necessary for such replacement or maintenance operations is much larger than displacement functional.
  • the object of the present invention is in particular to achieve in a simple way a connection system disconnectable better suited to such situations.
  • the outward and return journeys of the carriage and the operation of the hooking members are controlled from the upstream assembly.
  • this invention has the particular advantage that, during disconnection, transport and reconnection, no intervention is to be carried out on the electrical network of the whole mobile.
  • FIG. 1 represents a view of a system according to the invention, an electrical connection being established by this system.
  • Figure 2 shows a view of this system during of a first phase of an operation undertaken for delete this connection.
  • Figure 3 shows a view of this system when this connection has been deleted.
  • Figure 4 shows a horizontal sectional view of a continuous casting mold of steel, this ingot mold capable of constituting the mobile assembly of the system of the preceding figures.
  • a carriage K is able to carry the upstream block GA for alternately transfer it, on command, between a front position making said connection and a position rear remote from GB downstream block.
  • This cart is suitable on the other hand to separate on command from this upstream block placed in this front position.
  • said deformable conductors CA connect this upstream block GA to the fixed set EA whereas, in known systems, it connects the downstream block to the mobile assembly.
  • the upstream block GA is for example made up of files females such as FA1 connected by conductors flexible to the electrical terminals of the fixed assembly EA. These conductors are collected in a flexible AC cable. These terminals are those of a BA power supply group.
  • the GB downstream block then consists of male plugs such as FB1. These plugs are connected by a cable rigid CB to electrical components belonging to supply to the EB mobile assembly.
  • the cards of at least one of the two blocks are mounted floating and insertion guides mutually complementary such as 2 and 3 (see Figure 3) are conventionally arranged to compensate possible inaccuracies in positioning.
  • the separation of the two connection blocks allows the mobile assembly to carry out more extra-functional trips that the functional movements authorized by the cables flexible.
  • the carriage K performs outward and return journeys on a fixed transfer route W (see Figure 3).
  • This path is defined for example by hollow guides 6 which guide rods 10 fixed to it cart.
  • the carriage K carries the upstream block GA sometimes during a forward movement PA-PB to bring it to its position before PB sometimes during a PB-PA return trip to bring it to its rear position PA away from the downstream block GB (see figure 3).
  • the system further includes hooking members rear and front LA and LB so that the upstream block GA which has been placed in its position before PB when moving go from carriage K to make said connection remains linked during the consecutive return movement of the trolley either at GB downstream block to maintain this electrical connection either to this carriage to remove this connection which achieves a disconnection.
  • the functional displacements D cause alternating displacements of the upstream block GA on a path linear W which is typically from 1 to 15 mm.
  • the transfer path W then follows this linear path.
  • This arrangement has the advantage following: when the functional displacements have been stopped and left the upstream block in a position non-predetermined stop, it suffices that the displacement go from carriage K is long enough for the carriage reaches this block regardless of the stop position of the last.
  • the functional displacements are typically formed by an alternating rectilinear translation.
  • the LB front hooks are driven by an actuator VB to hook the upstream block GA to the block downstream GB and to get it. They are preferably carried by the upstream block.
  • the rear hooking members LA are driven by a VA actuator to hang the upstream block to the carriage and to unhook it. They're from preferably carried by the K cart.
  • Functional displacement D and transfer path W guiding the carriage K are for example vertical, the position before PB of the upstream block GA being above its position rear PA.
  • the fixed set EA further carries a movable protective cover 12 and a actuator 14 for bringing this cover above the block upstream GA and thus protect the latter when it is in its rear position PA.
  • this actuator discards this cover of the path of this block and of the carriage K during carriage movements.
  • This protective cover can also be placed manually on the GA upstream block.
  • Connection plugs such as FA1 and FB1 are typically adapted to the passage of electrical currents greater than 400A, for example 1000A.
  • the system according to the invention advantageously finds application in a continuous casting installation vertical of a metal such as steel when the whole mobile EB is an oscillating ingot mold.
  • Said functional displacements D are then constituted by a vertical oscillation which is imposed on this mold to avoid adhesion of the metal 16 to the cooled wall 18 of this mold.
  • This cooled wall causes a surface solidification of a liquid metal net crossing the mold under the effect of gravity. She is cooled by a circulation of water 20 between it and a outer wall 22. Extrafunctional displacements more of this mobile assembly are linked to the removal of a used ingot mold and the installation of a replacement.
  • the ingot mold includes inductors such as 24 and 26 constituting said electrical members to be supplied and ensuring electromagnetic stirring inside the metal thread 16 passing through this ingot mold.
  • All fixed EA is a fixed frame of this installation. Terminals of this fixed set are those of a group BA power supply supplying these inductors by via the two so-called GA and GB connection blocks.
  • the mobile assembly could however also be by example consisting of a vibrating part of a conveyor shaking if this vibrating part were to wear electric power components such as a motor causing an eccentric mass to maintain the shaking.
  • the present invention allows easy and remote control and quickly perform connection operations and electrical disconnection on circuits suitable for driving significant intensities, all without any intervention manual on electrical components.
