Definitions
- the invention relates to a support frame for traction-powered hoists with a Rope drum, with at least two arranged between two lateral stimulating elements Longitudinal beams, the ends of each in the area of the stimulus over the Longitudinal direction are fixed in their position.
- Such a support frame is known from DE 746 602 C, the end elements are plate-shaped.
- the support frame can be further configured in an advantageous manner.
- the stimulating elements with a clamping element namely a threaded rod are braced against each other in the longitudinal direction of the longitudinal beams, such that the ends of the side members thereby at least in the stimulation elements Are fixed in the longitudinal direction, a significant reduction in effort Assembly of the winch achieved.
- the use of such a tensioning element Bracing the stimulation elements also allows the side members to be so to design that a particularly stable and torsion-resistant support frame construction arises.
- the side members interact with the tensioning element, but they serve the solution according to the invention primarily the dimensional stability of the support frame, especially against twisting, so that, for example, any longitudinal beam Hollow profile cross-sectional shapes with high rigidity can be used without disadvantage for the Stability of the entire frame.
- the clamping element is as Threaded rod with at least at the ends, each with at least in the area of Rod ends formed external thread.
- the end elements are preferred plate-shaped.
- One of the two stimulus elements has one Receiving opening with internal thread, which is used to receive one end of the Threaded rod serves; and the other of the two stimulus elements is with one Provide passage opening for the threaded rod, so that this over the stimulus protruding end of the threaded rod can be provided with a nut.
- the nut By Tightening the nut, i.e. by screwing on the threaded rod, they are Stim elements via the intermediate longitudinal beams in the longitudinal beam direction easily clamped against each other.
- the invention proposes that the side member has a cross section with a U-profile has, whereby a particularly high dimensional stability is achieved.
- a simple fixation of the longitudinal beam ends to the end elements at high Dimensional stability is achieved by depressions that shape the longitudinal beam ends are complementary.
- high dimensional stability can also be achieved by using the Projections arranged on the inside of the end elements for fixing the Longitudinal beam ends can be achieved.
- These projections advantageously point from Device parts of the end elements formed on and / or the stop surfaces Projections are designed as cams.
- a further simplification of the support frame without reducing the dimensional stability but with a reduction in weight can be achieved in that the rope drum via, for example, slid-on bearings directly on the threaded rod, which as Axis of rotation is effective, is supported.
- the passage of a drive shaft is thereby achieved through an opening in at least one of the end elements.
- the drive shaft is expediently with external teeth and the inside of the cylindrical outer wall of the rope drum at least in the corresponding area with internal teeth into 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.
- the form between the two side end elements 1, 2 in the form of End plates 1a, 2a, which are arranged substantially parallel to one another at a distance are, with the transversely arranged above and below longitudinal beams 3 den actual supporting frame, within which a rotatable cable drum 4 via bearing 5 is supported directly on a clamping element 6 designed as a threaded rod 6a.
- the threaded rod 6a is parallel to the longitudinal beams 3 arranged.
- the threaded rod 6a has an external thread at the ends 7 provided; for receiving one end of the threaded rod 6a is used centrally in the end plate 1 formed opening 8, which with a corresponding Internal thread 9 is provided so that one end of the threaded rod 6a Screw connection is firmly connected to the end plate 1a.
- the other end of the Threaded rod 6a protrudes through a likewise central opening 10 in the end plate 2a extending beyond this so that by means of a nut 11 a Screwing the end plates 1a, 2a is made possible via the threaded rod 6a.
- the cable drum 4 rotatably supported on the threaded rod 6a via the bearings 5 is driven by a drive shaft 12 provided with external teeth, which for this purpose is formed in the longitudinal direction in the inner surface of the cable drum 4 Internal toothing engages; the drive shaft 12 penetrates the face plate 1 through a opening provided for this purpose.
- FIG. 2 shows a simple, yet very effective fixation of the longitudinal beams 3 on the end plate 1a, 2a;
- Fig. 3 shows a partial section along the section line A-A 2.
- the end plate 1 a, 2 a is at the associated points Provide protrusions.
- this is at the edge the end plate 1a, 2a arranged projection as a stop bar 13 with cuboid cross-section, the stop surface parallel to Longitudinal direction of the support frame runs.
- the longitudinal beams 3 have a U-profile which is dimensioned so that the End of the longitudinal beam 3 - as shown in the figures - in each case in the form gap formed by the cams 14 and the stop bar 13 can be used.
- the Distance of the cams 14 is chosen so that the outer surfaces of the inner Side surfaces and the inner bottom surface of the longitudinal beam 3 used Touch condition, which prevents a lateral displacement of the side member 3 becomes.
- the stop bar 13 can also be designed as a cam his. It is only important that the side member 3 is essentially free of play between the Projections 13, 14 can be used in a form-fitting manner.
- FIG. 4 is another variant in partial section across the support frame according to Fig. 1 shown with which a play-free fixation of the side members 3 is guaranteed becomes.
- the end plates 1a, 2a at the appropriate points Wells in the form of slot-like recesses 15 with a U-shaped Cross-section is formed and the recess is in shape to the shape of the Complementary.
- This design variant is also important the side member fixation that by inserting the side member 3 in a essential play-free positive connection between the end plates 1a, 2a and the side members 3 can be produced.
