Definitions

  • the invention relates to a loading device for transporting charging grates in heat treatment furnaces, consisting of one or more chain strands carrying the charging grids, running in guide rails and driven by chain wheels, which are composed of individual chain links provided with rollers.
  • Heat treatment furnaces exist e.g. from a high temperature zone and a loading table. There may also be cooling and quenching zones, each separated by doors.
  • Charging devices for charging such heat treatment furnaces are known in which the charging grates are moved through the treatment zones of the furnaces with chain strands running in guide rails and driven by chain wheels.
  • the transporter follows with the help of cams and pawls on the chain strands, which engage in the charging grates.
  • a generic loading device for heat treatment furnaces is known from DE-AS 1279706, in which the chain strands are composed of individual chain links provided with impellers and the charging grids are transported with the aid of cams.
  • this device has the disadvantage that the charging grates cannot be moved directly into the furnace, but must first be set down and then ground over steel rails and / or furnace stones, which can considerably limit the service life of the grate.
  • the guide rails extend into the heat treatment furnace, that on the end of the chain strands facing the heat treatment furnace over a length that corresponds approximately to the length of the charging grates, two upward points on the axes of the chain links Rocker arms are pivotally attached, at the end of which supporting beam segments are attached, and that at the end of the chain links carrying the supporting beam segments facing away from the heat treatment furnace, a support stop and a Hall tenocke are each fastened to the chain strands immediately behind the last rocker arms and in each case on the last supporting beam segment.
  • a supporting beam segment is preferably carried by two or three chain links each. It can also be advantageous if the first and last support beam segments are provided with a roller at the outer end.
  • the chain strands can be attached to the heat treatment furnace in a stationary manner.
  • a charging trolley which also carries one or more front derailleurs, which can engage in single-lever rocker arms and are provided with a bracket that projects resiliently above the level of the supporting beam segments at the side of the supporting beam segments.
  • This loading device has the advantage that the charging grates are lifted from the base and put down directly at the destination without being dragged over steel rails or furnace stones and thus have to be exposed to high tensile and bending stresses which severely impair the service life of these charging grates, especially at high ones Treatment temperatures.
  • Figures I to 111 schematically show an exemplary embodiment of the loading device according to the invention, Figure 1 showing a plan view, Figure 11 a longitudinal section along a chain strand and Figure 111 a cross section through a chain strand according to line A-A.
  • the loading device consists of two chain strands (1) which are guided in guide rails (14) and driven by chain wheels (8). These guide rails (14) are located both on the charging trolley (15) and in the working area of the heat treatment furnace (16) and are limited by a fixed stop (12).
  • the chain strands (1) are composed of the individual chain links (2), which are provided on both sides with rollers (9). Swiveling rocker arms (3) are attached to the axes (7) of the chain links (2), which support beam segments (4).
  • the outer supporting beam segments (4) are each provided with a roller (5) that can roll on fixed surfaces when lifting and lowering the supporting beam segments (4).
  • the support beam segments (4) are dimensioned so that they form a continuous support beam in the erected as well as in the lowered state.
  • a support stop (6) is fixedly connected to the chain strand (1) and sits on the end of the chain strand (1) facing away from the heat treatment furnace directly behind the last rocker arms (3).
  • a holding cam (17) is attached to the last supporting beam segment (4).
  • One or more rocker arms (3) are provided with overturning lugs (10), in each of which a front derailleur (11) can engage, which can lower the supporting beam segments (4) raised by the support stop (6) by moving the rocker arms (3) to the other Be tipped over.
  • These derailleurs (11) are provided with a bracket (13) which projects laterally above the supporting beam segments (4). The result of this is that when the support beam segments (4) are loaded with a charging grate the bracket (13) is pressed down and the front derailleur (11) cannot function.
  • the support beam segments (4) erected by the support deflection (6) are tipped over when the front derailleur (11) is passed over by engaging in a corresponding knock-over nose (10), so that they rest on the chain links (2) and are placed under the charging grate.
  • the front support beam segment with the roller (5) approaches the fixed stop (12)
  • the support beam segments (4) and thus the charging grate are raised and can thus be removed from the heat treatment furnace.
  • the support stop (6) in the chain wheel (8) is turned into the vertical position, the supporting beam segments (4) lose their support, are therefore lowered and place the charging grate on the charging trolley (15).
