Definitions

  • the present invention relates to devices for lifting a casting table which make it possible to straighten such a table from a horizontal position used for casting, in particular a concrete panel, to a vertical position allowing the demolding of this panel.
  • the invention provides a device for lifting a casting table, of the type comprising means for raising the table by rotating it around a first pivot parallel to the 'one of its sides, mainly characterized in that it further comprises: two synchronization pulleys whose axes are parallel to the pivot axis of the table; first two return pulleys; two second idler pulleys; a funicular cable mounted on these pulleys and having between the synchronization pulleys and the first return pulleys two synchronization strands perpendicular to the pivot axis and located in the same plane, and between the first and second return pulleys respectively two other crossed strands so that the synchronization strands move in the same direction between the synchronization pulleys and the first return pulleys; two synchronization sockets fixed respectively on the two synchronization strands at the same distance from the synchronization pulleys; and rigid connecting means fixed on one side to
  • a casting table 101 is shown in an intermediate position between the flat casting position and the vertical demolding position. It pivots around one of its sides along an axis of rotation 102 under the action of lifting means such as jacks which have not been shown.
  • the synchronization means which make it possible to balance the thrusts during lifting comprise two connecting rods 103 and 104 of the same length which are fixed under the table at the same distance from the axis of rotation 102. These connecting rods are articulated on these fixing points on one side, and on the other on carriages 105 and 106 which slide on horizontal rails, not shown. These trolleys act as synchronization sockets on the cable.
  • the carriages are secured to a funicular cable 107 which is mounted on a set of pulleys 108 to 113 according to a kinematics such that the carriages move perpendicular to the axis 102 and that the movement of one of the carriages is identical to that of the other.
  • a funicular cable 107 which is mounted on a set of pulleys 108 to 113 according to a kinematics such that the carriages move perpendicular to the axis 102 and that the movement of one of the carriages is identical to that of the other.
  • the kinematics of the funicular cable with its pulleys is similar to that which allows to move a rule parallel to itself on a drawing table.
  • the pulleys 108 and 109 have a common horizontal axis or two separate axes parallel to the axis of rotation 102 of the table 101.
  • the pulleys 112 and 113 have a common vertical axis directly above the pulley 108 relative to the axis 102 and the pulleys 110 and 111 have another vertical axis common to the plumb of the pulley 109.
  • the funicular cable 107 starting for example from the carriage 105, will be wound on the pulley 108, leaves towards the pulley 113 which is located under the pulley 112, rotates 90 ° under this pulley 113 to go up towards the pulley 110 which is located above the pulley 111. It rotates 90 ° on this pulley 110, starts again towards the pulley 109 in s 'hooking to the passage on the carriage 106. It then winds on this pulley 109 to start again towards the pulley 111, redo a change of direction at 90 ° on the latter and go up towards the pulley 112 by crossing with the strand which was going from pulley 113 to pulley 110.
  • An improvement making it possible to avoid slipping of the cables in the pulleys and to limit the effects of the elasticity of these cables consists in securing (by keying for example) the pulleys 108 and 109 on the same shaft 114. Under these conditions, as pulleys 108 and 109 pulleys having a self-locking V-shaped groove which prevents the cable from sliding in this groove.
  • the pulleys 110 to 113 have a groove of any shape, for example round, which is easier to machine.
  • This improvement also makes it possible to put in parallel any number of identical devices, which makes it possible to multiply the number of synchronization points for lifting tables which have very large dimensions or to put tables in series.
  • these devices are placed one beside the other, each with two connecting rods and a funicular cable.
  • the movement of the cables, and therefore of all the devices, is synchronized by the monolithic or compound shaft 114 which is common to all the devices and which causes synchronization via the pulleys of all the devices homologous to the pulleys 108 and 109.
  • a first embodiment of a casting table provided with a device conforming to the theoretical diagram of FIG. 1 is shown in the casting position in FIG. 2 and in the demolding position in FIG. 3.
  • the table 101 rests for casting on the frame 201 which supports the pulleys 108 to 113.
  • the pulleys 108 and 109 are carried by the transverse shaft 114 seen from the front in the figures. This shaft is parallel to the axis 102 (possibly formed of a pivot with several elements) around which the table 101 pivots and which is itself supported by the chassis 201.
  • Two jacks of which only one 202 is shown in the figures, are articulated by their bodies on the frame 201 and by their heads on the underside of the table 101. The lower parts of these jacks possibly plunge into a pit provided under the frame . By deploying the jacks push the casting table from the position shown in fig. 2 to the position shown in fig. 3.
  • the funicular cable travels along the kinematic path defined by the pulleys 108 to 113.
  • Two synchronization carriages 105 and 106 of which only the carriage 105 has been shown, are fixed on this cable and come to rest on two rails of which there is n 'has shown in the figure that the rail 205 which extends between the pulley 108 and the pulley 112 under the corresponding strand of the funicular cable.
  • a connecting rod 103 is articulated between the carriage 105 and the fulcrum of the jack 202 on the table 101. This arrangement simplifies the articulation of the connecting rod and the jack head on the table by bringing them together on the same axis. , which is not an obligation.
  • the pivot 102 permanently supports the weight of the casting table and of the slab which is cast on it. During the casting operations, the concrete is vibrated to make it more homogeneous and these vibrations are transmitted in particular by the pivot 102.
  • the table 101 rests during all the casting operations, including the vibration step, on the rest stops 301 which are provided so as not to transmit the vibrations.
  • the pivot 302 is itself separated into two parts, one which is integral with the table 101, and the other which is integral with a rocker 303.
  • This rocker comprises at least two identical elements located at each end of the table.
  • Each element is L-shaped, one arm of which rises and carries one of the parts of the pivot and the other arm of which extends horizontally under the table, being articulated on a second substantially central pivot 304 which allows it a slight clearance allowing to release the pivot 302 outside of the demolding operations.
  • This pivot 304 can be offset according to a study sketch.
  • This horizontal part of the lever opposite the vertical part has a horizontal axis 314 parallel to the pivot 302, on which are keyed two pulleys 108 and 109 for synchronization.
  • This axis also supports a fixed rectangular frame 305 which can oscillate around one of its sides on the axis 314 and whose lower side opposite this axis supports four pulleys 110 to 113 defining with the pulleys 108 and 109 the kinematic path of the synchronization cable 107.
  • the strands of this cable cross at the bottom of the fixed chassis respectively between the pulleys 110, 112 and 113, 111.
  • a mobile chassis 306 Inside the lateral sides of the fixed chassis, which are in the form of a gutter, slide two lateral sides of a mobile chassis 306, itself rectangular.
  • the lower side of this movable chassis comprises two parts 307 and 308 which project beyond the fixed chassis in order to be fixed on the two lateral strands of the cable 107 which move in the same direction in the movement of this cable.
  • These parts form synchronization sockets similar to the carriages 105 and 106 of the first embodiment.
  • the movable chassis will move in a parallel movement to itself in the fixed chassis up or down without tending to get crooked and exerting an equal thrust all along its upper part.
  • This upper part is formed by a push bar 309 which is connected to the lower part of the fixed frame by means of a set of jacks such as 310 and 311 which allow this push bar to be pushed back, and therefore the assembly of the mobile chassis, upwards, synchronization being ensured by the device comprising the funicular cable.
  • these cylinders do not are just one example of lifting means. These can be very diverse and include, for example, a hoist.
  • the jacks are actuated and cause the push bar to mount in abutment against the table 101 by means of a third set of pivots 312. The table and the push bar are then locked and secured.
  • the fixed frame and all the members that it supports pivot themselves around the axis 314 so as to continue to exert the thrust via the bar 309 and the pivots 312 on the casting table.
  • the movement ends when the table is vertical.
  • the thrust beam 309 will advantageously be common. to all of the movable frames 306 by extending all along the devices placed one next to the other.
