Definitions
- the invention relates to a winch with an axially displaceable winding drum according to the preamble of claim 1.
- winches find e.g. in lifting cranes with a carrying cable use, wherein the support cable is connected on the one hand, for example by means of a holding device with a load and on the other hand by means of arranged on a frame winch for lifting the load can be wound up.
- the tension cord can be wound up in an orderly manner on the winding drum, in particular in such a way that the tension cord runs in parallel juxtaposed turns around the winding drum and, if appropriate, several layers of turns are arranged one above the other in order to be wound up.
- various devices are known in which a cable is guided via a guide device to the winding drum, wherein the guide device simultaneously moves axially along the winding drum upon rotation of the winding drum.
- the guide device is acted upon by transverse forces through the guided rope. This can lead to an unwanted wear of the parts rubbing against each other and an increased energy consumption for the operation is required. Abrasion and other debris can accumulate on the guide means, which may require regular maintenance.
- the DE 1 053 757 B shows a winch with the features of the preamble of claim 1.
- a cable drum which is arranged axially displaceably on a central square shaft.
- the square shaft forms the axis of rotation and acts as a drive actuator for the rotation of the cable drum.
- a concentric cam is connected, which rests against a control cam.
- the cable drum By a pressing against the control cam cam contour of the cam, the cable drum during its rotation is moved back and forth and the cable wound in layers.
- Another generic device is in the DE 732045 C described.
- a cable drum is mounted rotatably and axially displaceably about a central drive shaft. Eccentric to the central shaft parallel to the shaft extending Mit supportivestangen are provided, which carry the cable drum and take the cable drum rotationally upon rotation of the drive shaft.
- the cable drum has an external thread on one of the eccentric driving rods. This runs in threaded sleeves, which are arranged on the cable drum. The rod with the external thread rotates around the drive shaft and is itself rotated by a planetary gear. Upon rotation of the drum, the threaded sleeves run along the external thread, whereby the cable drum is displaced along the rod.
- different mutually movable components and transmission devices are used, which can lead to design and adjustment effort.
- the invention has for its object to provide a reliable, robust and comparatively simple winch, which allows an orderly winding and unwinding of the tension cord.
- the winch is used for winding and unwinding a tension cord, which in the present context is flexible and windable (for example a rope, a chain or a belt).
- the winch has a winding drum rotatable about its central axis. Upon rotation of the winding drum, the tensile strand is wound up or unwound in turns which extend around the winding drum.
- a rotary actuator is provided, which acts on the winding drum.
- the winding drum is arranged such that it is longitudinally movable along its central axis. The longitudinal movement thus takes place with respect to a stationary reference, e.g. a fixed base of the winds.
- a threaded rod which extends in such a way that the central axis of the winding drum in the threaded rod runs.
- the threaded rod has an external thread.
- the winding drum runs by means of a counter thread on the external thread of the threaded rod.
- the mating thread rotates about the external thread and the rotation of the winding drum movement is coupled with a translational movement along the threaded rod.
- a displaceable guide for specifying the turns is not mandatory for this purpose.
- the tension cord can be guided to the winch at a fixed inlet or outlet position. As a result, the wear of the pull string and other moving parts can be reduced.
- the axial displacement of the winding drum is carried out in particular without additional transmission devices, which reduces the construction and maintenance costs. Overall, this allows a robust and compact design.
- the rotary actuator has at least one cam shaft extending parallel to the central axis and eccentric, i. offset radially, is arranged to the central axis.
- the driving shaft is drivable in a circular path about the central axis and cooperates with the winding drum. Since the cam shaft is eccentric to the central axis, a torque with respect to the central axis can be transmitted to the winding drum.
- the rotary actuator advantageously comprises a rotationally drivable actuator base part, for example a base plate.
- the actuator base part in particular comprises a central pivot bearing, in which one end of the threaded rod is mounted, so that the actuator base part is rotatable about the central axis.
- the central axis passes through the pivot bearing.
- the rotatable actuator base part simultaneously provides the end bearing for the (in particular non-rotatable) threaded rod.
- the actuator base part may e.g. have a flange, via which a connection with a drive shaft of a rotary drive takes place.
- the at least one driver shaft is arranged eccentrically offset to the central pivot bearing on the actuator base part.
- the cam shaft may be fixedly disposed in the actuator base part, e.g. be held fixed in a recess of the Aktorbasisteil.
- the driving shaft can also be rotatably arranged in the actuator base part.
- the rotary actuator comprises a plurality of driver shafts of the type mentioned, which are arranged in a symmetrical arrangement eccentrically about the central axis (and in particular about said central pivot bearing) around.
- two driving shafts are provided, which are arranged opposite one another with respect to the center axis (or with respect to the central pivot bearing, if provided).
- the threaded rod does not rotate during rotation of the winding drum.
- one end of the threaded rod can be fixed in a rotationally fixed manner to a base of the winch.
- threaded rod is arranged completely immobile in the wind.
- the base of the winch may be, for example, a base part with a base flange, by means of which the winch can be fastened to a higher-level device.
- the winding drum has a bearing in which the driving shaft is mounted longitudinally displaceable (i.e., displaceable in directions parallel to the central axis). Through the bearing, the winding drum can move axially along the central axis and along the drive shaft and can thus be driven in rotation independently of its axial position.
- the bearing is arranged in particular eccentrically to the central axis.
- the bearing is designed both as a linear bearing (sliding bearing), as well as a pivot bearing, so that upon rotation of the winding drum tilting is avoided.
- the winding drum may have a carrier part with a central passage for the threaded rod.
- the bushing coaxially surrounds the central axis.
- the support member may also comprise an eccentric to the central passage arranged drive section, on which the rotary actuator for driving the winding drum acts on them.
- the drive section has in particular the bearing for the said drive shaft.
- the mating thread can advantageously be formed by an internal thread in the central passage of the carrier part, so that only a few components are needed.
- the internal thread rotates coaxially around the central axis (and also the threaded rod).
- a simple assembly can also take place in that a threaded sleeve is fitted with an internal thread in the central passage.
- the external thread is designed as a cross thread with two opposing thread profiles. This runs in one defined winding direction driven winding drum along the threaded rod back and forth. This makes it possible to wind the turns of the pull string in successive layers one above the other.
- the two counter-rotating thread profiles are connected to each other in particular in their end portions.
- the two thread profiles merge into each other in their end sections and form reversal points of the cross thread.
- the rotating winding drum runs back and forth along the external thread.
- the winch can be adapted to different purposes by the geometric configuration of the external thread and / or the counter thread.
- the rise height of the external thread and / or the counter thread corresponds to a predetermined or desired distance dimension of the turns.
- the distance measure indicates the distance with which the tension cord should be wound on the winding drum. It is conceivable, for example, that the height of rise corresponds to a thickness of the tension cord. As a result, the turns are directly next to each other.
- the winding drum on an outer winding surface can be designed substantially cylindrical.
- the winding surface has a spiral-like circumferential surface groove, by means of which windings are guided for the tensile strand and are arranged on the winding surface. As a result, the tension cord is defined and unwound.
- the Figures 1-3 show a winch 10 for winding and unwinding a tension cord 12 (here: a rope), which in the longitudinal sectional view of FIG. 2 is schematically visible.
- the winding drum 10 includes a rotary drive 14 (for example, electric motor), which is optionally connected via further units (for example, braking device 16 and / or gear 18) with a rotary actuator 20.
- the rotary actuator 20 is intended to drive a winding drum 22 for rotation about its central axis A.
- the winding drum 22 has a cylindrical, outer winding surface 24, which may be provided with at least one spiral-shaped surface groove 26 (see. FIG. 2 ).
- a threaded rod 28 which has an external thread 30 (see. FIG. 3 ) having.
- the winding drum 22 includes a support member 32 having a central passage 34 through which the threaded rod 28 passes.
- the central passage 34 has a mating thread 36 which runs on the external thread 30 of the threaded rod 28.
- the mating thread 36 may e.g. be formed by an internal thread 37 of a threaded sleeve 38, which e.g. is fitted in the support part 32.
- the winding drum 22 may be constructed in several parts and e.g. be bolted to a final flange 39.
- the support member 32 Eccentrically to the central passage 34 (i.e., offset radially of the central axis A), the support member 32 provides a driving portion (at reference numeral 50) on which the rotary actuator 20 acts to rotatably drive the winding drum 22.
- the rotary actuator 20 may e.g. two take-up shafts 40 symmetrically disposed with respect to the center axis A on an actuator base 42 and e.g. are fixed by means of a pin fuse 44.
- the Aktorbasisteil 42 has a central pivot bearing 46, in which the threaded rod 28 is rotatably mounted.
- the pivot bearing 46 is formed for example as a ball bearing and can be secured with a locking ring 48.
- the driver shafts 40 extend through corresponding passages in the drive section of the carrier part 32, where they are longitudinally displaceably received in bearings 50 and preferably also rotatably received.
- the rotary bearing 46 opposite end of the threaded rod 28 is in a base 52 of the winch 10th fixed.
- the base may be provided by a mounting flange with which the winch can be fixed externally.
- the Aktorbasisteil 42 opposite ends of the driver shafts 40 are received in a base plate 54 and secured for example by means of pins 56.
- the base plate 54 in turn has a central pivot bearing 58 (eg ball bearings), through which the threaded rod 28 is guided, so that a rotation around it is possible.
- the threaded rod 28 may be secured against rotation in the base 52 via a feather key 60 (eg with a washer 62 and a screw 64). By removing and optionally replacing the key 60, the position of the threaded rod 28 along the central axis A can be adjusted.
