Definitions

  • the invention relates to a device for lifting tracked vehicles according to the preambles of claims 1 and 5.
  • the invention is therefore based on the object of creating lifting gear, in particular for heavy tracked vehicles for fast ship loading, which can withstand exceptionally high loads and in which no torsional forces can be transmitted to the caterpillar track.
  • the device is designed according to the invention so that no torsional forces are transmitted to the caterpillar by the loads occurring when lifting, which can lead to deformations and damage to the chain and the drive.
  • 1 is a side view of a tracked vehicle with lifting gear
  • FIG. 1 is a front view of FIG. 1
  • FIG. 3 is a rear view of FIG. 1,
  • FIG. 4 shows a tracked vehicle in side view with a lifting device in an enlarged view
  • FIG. 6 is a side view of FIG. 5 with a crossbar
  • FIG. 7 is a side view of another embodiment of a lifting device
  • FIG. 8 is a partial representation of the front and rear area of a tracked vehicle with lifting pre-lifting devices according to FIG. 7 in engagement
  • FIG. 9 is a side view of a tracked vehicle with cross members attached to auxiliary and carrying cables,
  • FIGS. 9 and 10 shows the front view of the tracked vehicle according to FIGS. 9 and
  • FIG. 11 shows the rear view of the tracked vehicle according to FIG. 9. 1 to 3, in the case of a tracked vehicle 1, lifting plates 5, 6, 7, 8 are suspended in track chains 9, 10 on both sides of the front and rear chain centers 1, 2, 3, 4, 7, 8. Two cross members 12, 13 are supported against the lifting plates under tension by cables 11. The ropes 11 are connected to a load cross member 14 which is carried by a lifting device, not shown.
  • FIG 4 shows a front lifting plate 6 and a rear lifting plate 7 with the two cross members 12 and 13.
  • the lifting plate 6 is suspended in the front chain section 2 of the track chain between the guide wheel 15 and the foremost Umlem roller 16, the lifting plate 7 in the rear chain center 3 between the rearmost roller 17 and the drive wheel 18.
  • FIG. 5 and 6 show, in an enlarged representation, the arrangement of the lifting plate 7 according to FIG. 4.
  • the lifting plate 7 is suspended between link bodies 19 with chain pads 19a in the track chain by means of laterally arranged, raised lower plates 20, 21 and upper plates 22, 23 and is supported against end connectors 24, which connect the chain bolts 25 to one another.
  • a support bracket 26 is welded to the lifting plate 7, in which the crossbar 13 is suspended.
  • the upper tabs 22, 23 are provided with welded-in stiffening elements 27, 28 and at their upper ends with plug pins 29, 30, which can be actuated via handles 31, 32.
  • FIG. 7 shows another embodiment of a lifting plate 107 resting on the running surface of the crawler belt 9, 10, which has a support tab 122 with which the lifting plate 107 is supported on an upper end connector 24 ′ of the crawler belt 9, 10 is.
  • a lever 120 is arranged, which projects between two end connectors, of which the lower Endverbin is ⁇ 24 'engages behind' the lever 120.
  • the lever 120 prevents the lifting plate 107 from falling out as long as it is not yet under the lifting load.
  • Support bracket 122 and lever 120 are only one chain link spacing apart, which, in contrast to the embodiment according to FIG. 6, makes it possible to hang the lifting plate 107 lower by one chain link pitch. It can thus be ensured that the lifting device does not come into contact with the guide wheel 15 and the drive wheel 18 in the load state.
  • the support bracket 122 is reinforced with a stiffening element 127 on which a securing bracket 129 is rotatably arranged.
  • the securing tab 129 lies flat on the back of the end connector 24 arranged below the upper end connector 24 ', as a result of which the drive wheel cannot have any spatial impairments. In the same way, a hindrance by the guide wheel can be excluded in the lifting device in the front area.
  • a support bracket 126 is fastened on the lifting plate 107 with a circular bearing surface 126a, on which a crossbar 113 with a circular cross-sectional area rests.
  • the crossbar 113 is enclosed by a securing bracket 126b which is detachably fastened to the support bracket 126. Due to the circular cross section of the crossbeams 113 and the circular bearing surfaces 126a, torsional forces are avoided.
  • 8 shows a tracked vehicle with lifting devices arranged on the front and rear chain center.
  • the suspension cables 111 are articulated at the ends of the crossbeams 112, 113.
  • the hinged to the track chain links front and rear lifting devices are identical and correspond to the exemplary 'üh- approximate shape according to Fig. 7.
  • the ends of the crossbeams on each side can be connected by tension members (not shown), e.g. be connected to one another by steel cables or link chains. This can ensure that if a crawler breaks, the cross-beam cannot be pulled over the idler or drive wheel, which would otherwise result in the tracked vehicle crashing.
  • the crossbars 112, 113 are first placed in front of and behind the tracked vehicle 1 on the ground, whereupon the load crossbar 14 is lowered from the height position A to the height position B, so that the purple shorter supporting cables 111 at the ends of each of the auxiliary cables Crossbeams can be attached.
  • the carrying ropes 111 first take the one marked in FIG. 9 with the reference number 111 ' Position one in which these are connected to the transverse traverses lying on the floor, which are provided with the reference symbols 112 'and 113' in their floor position.
  • the crossbeams 112 'and 113' are pulled inwards in the direction of the arrows Q and come to rest on the bearing surfaces 126a of the lifting devices hooked into the track chains, where they are then enclosed by the securing brackets 126b .

Abstract

L'invention concerne un cadre de levage pour soulever des véhicules à chenilles lourds sans transmission de forces de torsion sur les chenilles. Ce cadre de levage comprend, disposées sur chaque brin de chaîne (1, 2, 3, 4), des plaques de levage (5, 6, 7, 8) accrochées au moyen d'attaches (20, 21, 22, 23) dans la chenille (9, 10). Un élément transversal (12, 13) accroché respectivement à la paire de plaques de levage avant (5, 6) et à la paire arrière (7, 8) est porté par des câbles (11) associés à un palonnier (14) et à un engin de levage.
