Definitions

• the invention relates to a winch according to the preamble of patent claim 1.
• Winches are used in numerous fields of application, ranging from operations on towing services to those 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.
• 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 sufficiently large 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 rope outlet and thus the load in its position remains 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.
• 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.
• the winch according to the invention advantageously no bulky pulleys are required, which would hinder a close erection.
• the im With regard to the forces acting compensated arrangement of the elements of the winch prevent the suspension and in particular the soft against torsion, serving as a roadway I-profiles of a Unterflanschfahrtechniks be twisted, which can otherwise lead to a disability of operation and damage.
• 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.
• Focus also hardly shift in the longitudinal direction of the I-beam. In this way, a uniform wheel load distribution of the chassis during operation on an I-beam under-belt suspension and safe operation with a small ground contact area is possible.
• 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.
• Arrangement of the elements of the winch on the support structure is provided so that at a predetermined AufwicklungsSullivan, for example in a half-wound rope, the weight components of the elements are completely compensated orthogonal to the axis of the departure point for the vertical cable departure.
• 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 corresponding forces can be absorbed particularly uniformly by a suspension device for the winch.
• the cable drum is arranged vertically in operation
• the cable guide device guides the rope to the point of departure for the vertical cable outlet.
• the cable guide device can be realized in a conventional manner either by firmly positioned rollers at a sufficient distance to the cable drum or by a winding device.
• the rope guide device ensures the fixation of the departure point for the vertical cable outlet and at the same time for a uniform winding of the rope. In this case, a particularly compact design is possible, wherein the winding device can take on both tasks.
• 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 cable drum is arranged horizontally in operation, wherein the cable guide means comprises a winding device and at least one guide roller, which guide the rope to the departure point for the vertical cable outlet.
• the cable drum during operation can also be arranged so that the longitudinal axis of the cable drum extends obliquely to a horizontal plane.
• the cable guide device then also has a winding device and at least one deflection roller, which leads the rope to the point of departure for the vertical cable outlet.
• the electrical control components are integrated into the winch itself, which are designed to control the operation of the winch at a fixed predetermined or variable rope speed. Apart from the power supply and any data lines, the winch is thus extremely independent and thus particularly compact and practical.
• the cable winch according to the invention is designed for operation on a running gear, in particular an I-beam under-belt running gear.
• a running gear in particular an I-beam under-belt running gear.
• the advantage results from the design according to the invention, that the winch with a punctiform rope outlet, which does not change during the winding process orthogonal to the stroke direction, offers the opportunity to move the entire winch by means of a lower cylinder drive. This is practically not possible in single-stranded operation in conventional types of winches, because the torsional moments on the roadway carrier in the prior art can not be practically avoided.

• 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.
• the drive unit 4 acts at 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 in the embodiment described above is that the weights of all elements of the winch, so the cable drum 1, the drive unit 4 and the control device 7 and any other components of the winch are so symmetrically distributed around the axis of the substantially vertical cable outlet 9 in that the center of gravity lies in the plane of the cable axis of the cable outlet 9 or lies in the cable axis of the cable outlet 9 itself.
• the cable drum 1 is arranged horizontally, the second embodiment is basically constructed very similar to the first embodiment.
• the cable 12 is first deflected by the winding device 2 onto a non-migratory cable run parallel to the axis of the cable drum 1 and guided over a deflection roller 11, from which the cable 12 then arrives at a further guide roller 10 from which the Rope 12 is then continued to the vertical cable outlet 9.
• the proper movement of the winding device 3 synchronous to the winding is not disturbing in the winding of the first embodiment, because it takes place in the pulling direction and therefore leaves the vertical cable outlet 9 at a fixed location without further facilities.
• pulleys 10 and 11 are naturally required to ensure that the fixed departure point is achieved with vertical cable outlet 9.
• Control device 7 and any other elements of the winch according to the changed position and position of the cable drum 1 are adjusted to obtain the required compensation and the desired center of gravity.

• 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 in order to at least partially take into account the variations due to the dead weight of the cable 12 in different unwinding states, the balance can be aligned to a predetermined unwinding state. 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.
• 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.
