Definitions

  • the invention relates to a support frame for hoists with a drum for traction means mounted between two lateral end elements and with at least two longitudinal beams arranged between the end elements, the ends of which are each fixed in position on the end elements.
  • hoist-operated hoists in particular electric winches, modularly from the electrical, motor, gear, cable drum, suspension means and support frame assemblies, the individual assemblies generally being releasably assembled, which enables a large number of combinations.
  • the main components of the winch are attached to the support frame; in particular, it takes up the bearings and the drive shaft of the cable drum.
  • a support frame consists essentially of two end plates, which are arranged parallel to one another at a distance from one another and are fastened to longitudinal members arranged between the end plates, the end plates being fastened to the longitudinal members via at least three screw connections per end plate.
  • a disadvantage of this known support frame for cable winches is the relatively large assembly effort required by the screw connections.
  • the drive shaft of the cable drum which is mounted in the end plates, requires solidly designed longitudinal members due to the associated mechanical loads on the support frame, which leads to a heavy weight of the support frame.
  • the support frame can be further configured in an advantageous manner.
  • the end elements can be braced against one another in the longitudinal direction with at least one tensioning element via the longitudinal members, such that the ends of the longitudinal members are thereby fixed to the end members at least in the longitudinal direction thereof, a significant reduction in the effort involved in assembling the cable winch is achieved.
  • the use of tensioning elements for bracing the end elements also makes it possible to design the side members in such a way that a particularly stable and torsionally rigid support frame construction is produced. This advantageous possibility arises in particular from the fact that the clamping function is realized by clamping elements specially provided for this purpose.
  • the longitudinal beams interact with the tensioning elements, but in the solution according to the invention serve primarily the dimensional stability of the supporting frame, in particular against twisting, so that any hollow profile cross-sectional shapes with high rigidity can be used as longitudinal beams, without disadvantage for the stability of the entire frame.
  • the tensioning element is designed as a threaded rod, each having at least at the ends with an external thread formed at least in the region of the rod ends.
  • the end elements are preferably plate-shaped.
  • one of the two end elements has a receiving opening with an internal thread, which serves to receive one end of the threaded rod; and the other of the two end elements is provided with a passage opening for the threaded rod, so that the end of the threaded rod protruding beyond the end element can be provided with a nut.
  • the invention proposes that the side member has a cross section with a U-profile, whereby a particularly high dimensional stability is achieved.
  • a simple fixation of the longitudinal beam ends on the end elements with high dimensional stability is achieved by depressions that are complementary to the shape of the longitudinal beam ends.
  • a high degree of dimensional stability can alternatively also be achieved by projections arranged on the inside of the end elements for fixing the longitudinal beam ends. These projections advantageously have stop surfaces formed by device parts of the end elements and / or the projections are designed as cams.
  • a further simplification of the support frame without reducing the dimensional stability but with reducing the weight can be achieved in that the cable drum is supported directly on the threaded rod, which is effective as an axis of rotation, for example by means of pushed-on bearings.
  • the passage of a drive shaft is achieved via an opening in at least one of the end elements.
  • the drive shaft is expediently provided with external toothing and the inside of the cylindrical outer wall of the cable drum is provided, at least in the corresponding area, with internal toothing in which the external toothing of the drive shaft engages.
  • FIG. 1 An embodiment of a support frame is shown in Fig. 1 as a longitudinal section.
  • Bearing 5 is supported directly on a clamping element 6 designed as a threaded rod 6a.
  • the threaded rod 6a is arranged parallel to the longitudinal beams 3.
  • the threaded rod 6a is each provided with an external thread 7 at the ends; an end 8 of the threaded rod 6a is provided with an opening 8 which is formed centrally in the end plate 1 and which is provided with a corresponding internal thread 9, so that one end of the threaded rod 6a can be firmly connected to the end plate 1a by screwing.
  • the other end of the threaded rod 6a protrudes through a likewise central opening 10 in the end plate 2a, which extends beyond the latter, so that a screwing of the end plates 1a, 2a over the threaded rod 6a is made possible by means of a nut 11.
  • Tightening the nut 11 causes the end plates 1 a, 2 a to be braced against one another via the longitudinal members 3 in the longitudinal member direction, so that a non-positive connection of the end plates 1 a, 2 a is achieved via the longitudinal members 3.
  • FIG. 2 shows a simple, yet very effective fixation of the side members 3 on the end plate 1a, 2a;
  • FIG. 3 shows a partial section along the section line AA according to FIG. 2.
  • the end plate 1a, 2a is provided with projections at the associated points.
  • the projection arranged on the edge of the end plate 1 a, 2 a is designed as a stop bar 13 with a cuboid cross section, the stop surface being parallel to the Longitudinal direction of the support frame runs.
  • two projections designed as cams 14 are provided on the end face, the longitudinal axis of which likewise runs parallel to the longitudinal direction of the support frame 7.
  • the longitudinal beams 3 have a U-profile which is dimensioned such that the end of the longitudinal beam 3 - as shown in the figures - can be inserted in a form-fitting manner in the gap formed by the cams 14 and the stop bar 13.
  • the distance between the cams 14 is selected so that their outer surfaces touch the inner side surfaces and the inner bottom surface of the side member 3 in the inserted state, whereby a lateral displacement of the side member 3 is prevented.
  • the stop bar 13 can also be designed as a cam. It is only important that the longitudinal beam 3 can be inserted in a form-fitting manner between the projections 13, 14 essentially without play.
  • FIG. 4 shows another variant in partial section across the support frame according to FIG. 1, with which a play-free fixation of the longitudinal beams 3 is ensured.
  • depressions in the form of slot-like recesses 15 with a U-shaped cross section are formed in the end plates 1a, 2a at the corresponding points and the shape of the recess is complementary to the shape of the longitudinal beam end.
