Definitions

  • the invention relates to a hoist for transporting containers provided with trunnions in a horizontal position, in particular transport containers with radioactive substances in nuclear facilities, essentially consisting of a crane hook mount, a torsion body and two trusses with stop tabs for the container support spigots.
  • hoists are used to dispose of nuclear plants of nuclear fuels in order to handle containers, in particular fuel element transport containers, in a horizontal position.
  • hoists are used, which are each specially designed for one or two types of containers of similar construction. These hoists consist essentially of a crane hook mount, a torsion body and crossbeams with the stop tabs for the container support pins. These hoists are essentially characterized in that they have four stop tabs which can be expanded by means of hydraulic servomotors in order to allow attachment to normally four container pins.
  • DE-OS 25 28 532 describes a device for securing loads on crane systems with a redundantly arranged cable suspension, which, however, no longer corresponds to the current state of safety requirements.
  • hoists are used, the stop plate links of which have two degrees of freedom, but the second degree of freedom is only used for the purpose of attaching the plates to the container pins.
  • DE-OS 23 64 928 describes how loads of a general type can be handled in a defined inclined position.
  • hoists of this type cannot be handled due to their size in the lock area of a nuclear facility.
  • no precautions are taken with such hoists to ensure the absolutely necessary stability in the event of failure of a link plate.
  • a hoist for motors which consists of a crane hook receptacle, torsion body and two crossbeams with stop tabs, the connection between the crane hook receptacle and the torsion body being effected via a spindle drive and both crossbeams being rigidly connected to the torsion body.
  • a hoist known from US Pat. No. 3,972,553 has stop tabs which can be pivoted about a pivot bearing in two positions.
  • such lifting devices cannot be used for containers with radioactive substances, since they do not meet the legal safety requirements in nuclear facilities and cannot be used for containers with different, changing trunnion spacings.
  • each cross member has a stop tab in the region of its ends, to achieve a statically determined load distribution, the other cross member is suspended in a pendulum manner on the torsion body, the stop tabs can be shifted continuously via spindles on supporting bolts or over to adapt to different container widths with them articulated swivel arms are pivotally attached to the crossbeams via swivel bearings via spindles and catch hooks are attached to the pendulum-suspended crossbeam to limit the pendulum movement between this crossbeam and the torsion body.
  • the redundancy of the sling gear which is necessary in the event of incorrect operation or failure of a link to prevent a container from falling, is achieved via the specially designed torsion body with damping elements that are able to safely absorb the dynamic forces that arise.
  • FIGS. 1 and 7 schematically show two exemplary embodiments of the lifting device according to the invention, while FIGS. 2 to 6 show construction details of FIG. 1.
  • the lifting device essentially consists of a crane hook receptacle (38) and a torsion body (1) with cross members (2, 3) attached to it.
  • the torsion body (1) is designed, for example, as a flat box-shaped body (1), which is made torsionally rigid in its interior with bulkhead plates. It is usually a welded construction made of sheet steel, which has a welded cross-beam (3) on one side and a pendulum-suspended cross-beam (2) on the opposite side.
  • the fixed crossmember (3) like the pendulum crossmember (2), is designed as a welded hollow profile with web plates, the upper and lower belt plates advantageously being connected by means of web plates.
  • swivel-mounted arms (9) are attached as swivel arms, which can be swiveled sideways continuously via spindles (20) around a bolt in the swivel bearing (10) with a defined angular deflection.
  • the stop tabs (4) are suspended on the head part of these swivel arms by means of articulated bearings (11).
  • the stop tabs (4) are provided in the lower area with the openings for receiving the container support pins (24).
  • Trap plates (23) (FIG. 3) are arranged above this.
  • latch plates (23) are provided with sliding bolts which bring about a positive locking with the container support pins (24) and ensure safe handling of the containers (15).
  • the swivel arms (9) are preferably driven in pairs with a drive spindle (20), the central bearing (32) of which is attached to the torsion body (1), via a chain-driven handwheel (33).
  • a lever (34) is welded to the hollow shaft of the swivel arms (9) at the upper end, via which the lever linkage connected by means of the lock nut (35) transmits the force.
  • the crane hook receptacle (38) is fastened to inserted supporting bolts (7) via welded-in upright web plates of the torsion body (1).
  • This crane hook receptacle (38) consists of support straps (5) standing vertically and displaceably mounted in support bolts (7), spacer ears (8) and latch brackets (6).
  • the spacer tubes (8) are flanged to the support brackets (5), the latch brackets (6) are mounted on one side in pivot bolts (12) and on the other side releasably connected with sliding bolts (13).
  • the support brackets (5) can be moved onto the support bolts (7) by means of drivers.
  • the pendulum-suspended traverse (2) is mounted on the torsion body (1) via a support bolt (39), wherein it rests in an elongated hole (14) as a bearing point.
  • the lifting device serves, above all, to receive and transport fuel element transport containers in a horizontal or in a defined inclined position that deviates from the horizontal.
  • a crane hook is positively attached to the crane hook holder (38).
  • the latch bracket (6) can be swiveled vertically upwards to insert the hook around the pivot pin (12).
  • the latch bracket (6) is brought into the closed position by means of the hook weight. This position is then locked using sliding bolts (13). Due to the movability of the crane hook receptacle (38) on the support bolts (7), the different centers of gravity of the transport containers (15) are compensated for.
  • the interchangeable spacer tubes (8) connect the brackets (5) to each other and establish the distances required for the respective crane hook.
  • the torsion body (1) transmits the forces to the opposite stop side by absorbing torsional forces. If a stop bracket (4) fails, it absorbs the forces from the container load and ensures that the remaining three stop brackets (4) hold the container (15) in place.
  • the crossbar (2) which is suspended from the elongated hole bearing point (14) by means of bolts, compensates for all tolerances and inaccuracies in the hanger and on the container and enables a statically determined load distribution.
  • this crossbeam (2) swings around the support bolt (39) in the elongated hole (14), it strikes the torsion body (1) after the clearance has been exceeded at the attachment points (36 or 37).
  • the swivel arms (9) are spread outwards and, after the stop openings of the stop tabs (4) are in front of the container support pins (24), are pivoted inwards by means of a chain using the handwheel (33).
  • the pins are inserted into the bearing shells of the stop plates (4) by slightly lifting the hanger.
  • the trap plates (23) (Fig. 3) are lowered and locked by means of bolts by hand, so that the stripped support pins (24) cannot slide out.
  • the different length dimensions or the different center distances of the container support pins (24) are compensated for by appropriate inclination of the stop tabs (4) via the spherical bearings (11).
  • the design of the torsion body (1) and the dimensioning of the stop plates (4) make it possible to hold a fastened transport container on two diagonally opposite stop plates. There is redundancy here, which offers a significant increase in safety compared to conventional hoists.
  • Fig. 2 shows the safety device mounted in the trunnion (19) of the pendulum traverse with the safety hook (16) schematically.
  • the damping elements (17 and 18) attached to the pendulum cross member (2) and to the torsion body (1) with their attachment points (36 and 37) can also be seen here.
  • Fig. 3 the stop plate construction is shown with a cut joint bearing (11). It shows the trap plate (33), which fixes the struck container support bolt (24) and thus the container (15) in its position.
  • FIG 4 shows an enlarged view of the swivel arm construction.
  • the swivel arms (9) are adjusted by means of the lockers (20) via lock nuts (21) and lever linkages (22) around the swivel bearings (10).
  • Figures 5 and 6 represent the crane hook mounting structure schematically.
  • the adjustment of the center of gravity is initiated via the spindle (25), the support straps (5) sliding over the support bolts (7).
  • FIG. 7 A special variant of the lifting device according to the invention is shown schematically in FIG. 7 with a torsion beam (1) arranged along the container axis.
  • the pendulum traverse (2) like the fixed traverse (3), lies transversely to the container axis.
  • the fixed crossmember (3) is screwed to the torsion body (1) and thus allows a further adjustment option that goes beyond the swivel ranges of the stop plates (4) (advantageous for extreme container dimensions).
  • the center of gravity of the hoist and container system is adjusted by roughly adjusting the pull tabs (26) in the individual bores (27) of the supporting webs (28) and by means of a fine adjustment device (25) of the pull tabs (26).
  • the crane hook receptacle (29) also has a trap plate design for the positive connection of the crane hook.
  • the width of the stop plates (4) is adjusted with the aid of a spindle system (31) via the support bolts (30) by moving the stop plates (4).
  • This variant according to the invention is preferably used where the spatial conditions are not extremely narrow and allow handling in front of the lock area.
  • the advantage according to the invention lies in the usability of the hanger for containers with excess widths and excess lengths.
