Definitions

  • the invention relates to a winch according to the preamble of patent claim 1.
  • Winches are used in many fields of application, ranging from operations on towing services to sol chen sail during gliding. In particular, they are also used as conveyor hoists, at events and in stage technology.
  • a conventional winch for this use consists of a cable drum on which a rope or a number of ropes is wound in one or more layers.
  • the cable drum is rotatably mounted about a drum axis, which is held by a frame or support, which is usually attached to the ground.
  • An adjacent or in the cable drum arranged drive usually an electric motor, rotates the cable drum via a corresponding gear and thus moves a load attached to the rope by the rope is unwound or wound up.
  • the unwinding and winding of the rope is often also using additional facilities that provide a regular winding.
  • the cable drum can also be brought to a standstill with a brake to prevent a crash of the load in case of failure of the engine. This is especially true for securing in the stage and event area, where the brake is designed for further safety as a double brake.
  • single-stranded or multi-strand winches can be used in combination with a fixedly positioned pulley, in which case the pulley to the cable drum must have a sufficient distance to ensure trouble-free and standard-compliant winding the rope to the cable drum.
  • multi-strand winches are used with direct rope outlet in combination with a bottom block, each two strands of rope are wound against each other.
  • the load does not change its position orthogonal to the stroke direction.
  • the winches per winding turn can be moved to the appropriate winding pitch, so that overall the cable outlet and thus the load remains in position perpendicular to the stroke direction.
  • single-stranded and multi-strand winches can be used in which the pulleys or rope rollers of the winding device are shifted per winding turn to the corresponding winding pitch. In this case, not the whole winch, but only the pulley is moved within the winch, so that overall the cable outlet and thus the load remains in position perpendicular to the stroke direction.
  • an embodiment with a vertical cable outlet is also to be moved horizontally in order to be able either to shift the load or to be able to use the hoist in different positions, this is achieved in two ways: Either a standing on the ground or hanging on the ceiling landing gear is provided with more than two rollers or guides, or a Unterflanschfahrtechnik.
  • the method using a Unterflanschfahrtechnik is considered economically advantageous and is therefore by the manufacturers of standard hoists, such as. B. chain hoists and winches widely used.
  • Cable winches according to the above examples with a vertical cable outlet also require in the installation on the ground in operation due to the required distance between the cable drum on the one hand and the pulley on the other hand, a relatively large footprint, so that a close arrangement of the individual lifting equipment is not possible.
  • a winch of the type mentioned above has become known, wherein a horizontally arranged winch is provided, of which a rope of a plurality of pulleys and a cable hook attached to the end are guided to a center of gravity to no load or load in a horizontal State.
  • the object of the invention is therefore to provide a winch with praxisförmigem substantially vertical cable outlet, which can be made compact and can be moved with the least possible load on the chassis.
  • the winch according to the invention has the advantage that the center of gravity of the winch from its own weight and payload, regardless of the attached load and the load position, essentially changes only by the weight of the rope to be wound. Due to the fact that the cable guide device has a winding device with a deflection roller, which guides the cable to the point of departure for the vertical cable outlet, the cable guide device ensures the fixation of the point of departure for the vertical cable outlet and at the same time for a uniform winding of the cable. In this case, a particularly compact design is possible, wherein the winding device can take on both tasks.
  • the winch according to the invention advantageously no bulky pulleys are required, which would hinder a close erection.
  • the compensated with respect to the forces acting arrangement of the elements of the winch prevent the suspension and in particular the soft against torsion, serving as a lane I-profiles of a Unterflanschfahrtechniks be twisted, which otherwise it can lead to a disability of the operation and damage.
  • the vertical arrangement of the cable drum regardless of the balanced arrangement has the advantage that at a small cable drum diameter, the weight of the cable drum and the drive components, in particular the transmission, is low and that nevertheless the ground contact surface is compact by the vertical arrangement of the cable drum.
  • a compact and lightweight winch can be realized in this new for mobile NOTEzugwinden construction.
  • the solution according to the invention is based on the idea, in particular to pay attention to the center of gravity of the winch and to specify this in a suitable manner.
  • This emphasis of dead weight and payload should namely, regardless of the load and the load position essentially change only by the weight of the rope to be wound. This applies at least in one direction transversely to an I-beam longitudinal axis located above it.
  • Such a design of the winch according to the invention with almost unchanged center of gravity also allows horizontal non-movable use, so without a chassis, a simple, economical and suspension mounting of the hoist, as in the support structure no or at least almost no moments are passed. This also allows a compact design of the hoist with a very small footprint during operation.
  • this weight is relatively small in relation to the total weight of the other components. If no fluctuating loads are present and there is a predetermined winding state of the rope, then one comes very close to the ideal state that no moments are exerted by the winch on the corresponding chassis.
  • the arrangement of the elements of the winch is provided on the support structure so that at a predetermined MewicklungsSullivan, for example in a half-wound rope, the weight components of the elements orthogonal to the axis of the departure point for the vertical Cable outlet are fully compensated.
  • the common support structure is provided on its upper side with min least one suspension lug, the bore for receiving a suspension device is located on the axis of the vertical cable outlet.
  • the weight components of the balanced winch are accommodated at a particularly suitable location.
  • the support structure has a plurality of suspension lugs on its upper side, wherein the holes for receiving suspension devices are arranged so that the winch regardless of the load and the load position at least about an axis, in particular the I-beam longitudinal axis balanced.
  • the holes will be symmetrical to the axis of the vertical cable outlet.
  • the cable drum can be arranged horizontally in operation, wherein the cable guide device has a winding device and at least one guide roller, which lead the rope to the departure point for the vertical cable outlet.
  • FIG. 1 shows the winch according to the invention with vertically arranged cable drum.
  • the cable drum 1 is rotatably mounted in a unitary support structure 6 in the form of a frame or a frame.
  • the drive unit 4 which is formed for example in the form of a slip-on with motor, brake and encoder.
  • the torque applied to the drive is introduced into the frame 6 via a torque support, which may be provided with an electronic load measuring device. Further details of such a drive are not relevant in the present case and are familiar to the person skilled in the art.
  • the cable drum 1 is arranged vertically.
  • the winding device 2 is guided synchronously with the cable outlet on the cable drum 1 in the guide 3 in order to redirect the rope to a punctiform cable outlet 9.
  • punctiform rope outlet is to be understood that the cable outlet does not migrate during operation, in particular does not shift orthogonal to the vertical stroke direction during the winding process.
  • the drive unit 4 acts on the one end of the drive shaft of the cable drum 1 and generates around the cable outlet 9 a counter-torque to the weight of the cable drum 1.
  • a control device 7 is provided in this case next to the cable drum 1 and arranged so that the weight based on the punctiform rope outlet 9 is balanced.
  • reference numeral 8 At the bottom of the frame 6 can be seen at reference numeral 8, a ground contact surface or ground contact feet, which are not shown in detail.
  • the essential aspect is that the weights of all elements of the winch, so the cable drum 1, the drive unit 4 and the controller 7 and any other components of the winch are distributed around the axis of substantially vertical cable outlet 9 so symmetrical that the focus in the level of the cable axis of the cable outlet 9 is located or in the cable axis of the cable outlet 9 itself.
  • FIG. 1 can be seen at the top of the support structure 6 is a schematically indicated tab 5 with a bore which serves to receive a suspension device for the winch. It can be seen that this hole is located in the vertical axis of the cable outlet 9 to accommodate the balanced with respect to the gravity components winch and hang if necessary.
  • a plurality of such tabs 5 may be provided at the top of the support structure 6, which are formed with corresponding through holes, which serve to receive a suspension. Such holes are then arranged so that at least in one direction, the winch is balanced regardless of the load and the load position.
  • the holes are mounted symmetrically to the axis of the vertical cable outlet 9, so that in the suspension of the winch turn the symmetrical with respect to the gravity components or balanced arrangement is not disturbed and the acting loads can be absorbed evenly.
  • the balance may be aligned to a predetermined deployment condition. For example, if a winch carries loads at a certain height during operation, it may be advantageous to design the winch from the outset so that at this (average) height the weight of the rope 12 is also balanced.
  • the steep 12 is guided by the winding device 2 directly via corresponding pulleys to punctiform, vertical cable outlet 9, so that the cable outlet 9 does not migrate orthogonal to the stroke direction during the winding process.
  • All components of the winch including the necessary electronics and control are arranged so that the center of gravity of all components, apart from the weight of the rope to be wound 12 are substantially balanced around the vertical cable outlet 9.
