Definitions
- the present invention relates to a free-fall winch with a drum which is rotatably driven by a winch drive, wherein a freefall brake is provided for braking the drum in free fall operation.
- Free-fall winches are used in various applications in which the rope wound on the drum of the winch or another pulling or lifting means such as a belt with high speeds over long distances to be unwound or discharged, the drum more or less resistant idle or possibly also with slight braking by the transmission resistors rotated. Such unwinding is sometimes referred to as a "free fall.” At least at the end of free fall, it is necessary to rapidly decelerate the cable reel to allow uncontrolled further unwinding of the rope and, consequently, slack rope on the winch drum and an unclean, confused set picture avoid.
- Such free-fall winches can be used, for example, in cable dredgers when a compactor mass is dropped onto the ground in free fall for soil compaction.
- a compactor mass is dropped onto the ground in free fall for soil compaction.
- the freefall brake must be braked so as not to create a slack rope on the winch drum. This process is cyclically repeated at short intervals, whereby the cooling oil of the free-fall brake and the friction coefficients of the brake body change. Accordingly, the excavator operator must adjust the braking of the free-fall winch again and again.
- a free-fall winch of the type mentioned initially shows, for example, the document EP 0 538 662 B1, in which the winch drive drives the drum via a two-stage planetary gear, which is accommodated in the interior of the drum.
- a sun gear of one of the planetary stages can be driven by the winch drive and on the other hand blocked by a holding brake.
- a planet carrier of one of the planetary stages is brought out via a shaft from the opposite end of the drum to be braked there by a freefall brake, which is supported on the counter-bearing shield.
- a Kelly winch is known in which during unwinding of the rope, the cable or an associated torque on the Drum is monitored.
- the winch drive is basically rotatably mounted on the drum, but supported by a hebeiförmige torque arm on the frame, wherein a measuring device detects the load of the torque arm to determine the supported torque.
- the winch drive is controlled in response to the detected load of the torque arm so that a certain load on the torque arm does not fall below and thus a torque associated with the drum and thus a corresponding residual tension on the rope is maintained to prevent slack rope.
- the document DE 10 2014 109 918 A1 shows a drill whose drilling tool can be lowered along a mast by a winch.
- a winch driving hydraulic pump is driven in response to a cable pull force, which is measured by a force measuring bolt on a pulley of the rope.
- the present invention seeks to provide an improved freefall winch of the type mentioned above, which avoids the disadvantages of the prior art and further develops the latter in an advantageous manner.
- a stable free-fall operation should be made possible regardless of fluctuations in the lubricant temperature and viscosity and changing friction coefficients of the free-fall brake pads.
- an overload protection of the winch in free-fall operation and a simple manual deduction operation should be possible.
- a controlled system for which purpose said control means may comprise a controller module which controls the braking force of the free-fall brake in dependence on the detected torque and a predetermined desired and / or reference variable.
- the said controller module can in this case take into account, for example, a desired braking torque, and adjust the braking force so that a deviation between the detected torque and the desired desired torque is as small as possible or remains.
- the said desired braking torque can be predetermined for example by the position of a brake pedal or a brake lever, wherein the actuating force of the free-fall brake is not forcibly controlled by the pedal or leverage force in the sense of a forced coupling between brake actuator and brake pedal.
- the travel and / or the actuating force with which the brake pedal or the brake lever is actuated is detected and provides the desired desired braking torque, said controller module then adjusts the operating force of the brake so that the actually achieved actual braking torque as close as possible to the desired setpoint torque comes.
- said controller module can also take into account a drum rotation speed and / or a cable outlet speed and adjust the brake actuating force of the free brake so that a desired drum speed and / or cable outlet speed is maintained with the smallest possible deviation.
- This can be the actual Drum speed and / or the actual rope drainage speed can be detected by means of a speed detector or a speed detector.
- the torque can be detected directly on the drive train with which the drum is driven, and / or directly on the free-fall brake and / or directly on an additionally present holding brake, wherein the torque detecting device advantageously directly to said drive train and / or directly the free-fall brake and / or directly associated with the holding brake.

- the free-fall brake can hold or release a sun gear or a ring gear of a planetary stage in the manner mentioned in order to transmit or not to transmit the drive movement of the winch drive to the drum.
- the aforementioned arrangement of the torque sensor on the motor shaft and / or the transmission input shaft is based on the consideration that the sum of all torques on the gearbox, which transmits the drive movement of the winch drive to the drum must be 0, which implies that the measured by the torque sensor Torque at the motor drive shaft and / or the transmission input shaft corresponds to the free-fall braking torque when the free-fall brake provides a corresponding braking torque in free-fall operation.

- the free-fall brake 11 can also be supported standing on the counter-bearing plate, as will be explained.
- the free-fall brake 11 is released.
- the winch drive 8 and / or the holding brake 10 is braked, so that the input shaft of the transmission 9 is fixed.
- the drum 2 can still rotate, since the dissolved sunken or ring gear is decoupled from the drum shell 3 by the released free-fall brake 11.
- the input side of the transmission 9 connected to the winch drive 8 has a torque corresponding to the braking torque of the free-fall brake 11, so that a torque induced by the free-fall braking torque can also be measured on the engine side.
- a detection device for detecting the torque in the winch drive 8 may be integrated, wherein the detection device 20, for example, may have a torque sensor 21, sitting on the motor shaft or the motor shaft circumferentially at least partially surrounded.
- a measuring element can also be arranged in the interior of the drive shaft when the drive shaft is hollow or has a corresponding cavity.
- the torque sensor 21 may also be located at the interface between the motor shaft and the transmission input shaft.
- the detected by the torque sensor 21 actual torque is supplied to a control device 30, by means of which the operation of the free-fall brake 11 is controlled or adapted.
- said control means may comprise a regulator 31 30 which so adjusts the force applied by the actuator 13 braking force in dependence on the detected actual torque that the bewirk of the free-fall brake 11 »msmoment close as possible to the desired target torque zoom occurs.
- the desired desired braking torque can be specified by a brake pedal or a brake lever whose travel and / or operating force can be sensed.
- a further reference variable can be supplied, for example in the form of a target speed of the winch, with the drum 2 in the free fall operation unwinds the rope.
- the controller 31 may be the
- Actuate control device 13 so that the achieved speed of the desired speed comes as close as possible.
- the influence of the oil viscosity and the change in the coefficients of friction of the free-fall brake 11 can be reduced or, at best, completely eliminated.
- the manual intervention of the machine operator can be eliminated, in particular to the effect that the brake pedal does not have to be pressed more or less vigorously.
- a control signal "free fall" can be entered, for example via a touchscreen, whereupon the free fall winch operates in free fall and the controller 31 adjusts the desired braking force to achieve a desired takeoff speed or drum speed Towards the end of the desired free fall to slow the winds again.
- the actual torque used for the control can also be detected on the holding brake 10.
- the holding brake 10 rotatably on stored, but supported by a support 40 against rotation, cf. Fig. 2.
- the support 40 which intercepts the rotation of the holding brake 10 in free-fall operation, may be associated with a torque sensor 21, for example in the form of a load cell to detect the load on the support 40 and thus the induced torque.
- the winch drive 8 can be stored stationary, for example, be firmly supported on the bearing plate.
- the actual value of the torque detected on the holding brake 10 is fed to the control device 30, in particular its regulator 31, in a manner similar to that described for FIG. 1, in order to regulate the free-fall braking operation.
- Fig. 3 shows a similar embodiment as shown in FIG. 2, wherein also here the actual value of the torque is detected on the holding brake 10.
- the holding brake 10 is in turn rotatably mounted, but supported by a support 40, so that the torque acting on the holding brake can be detected by detecting the load of the support arm.
- the winch drive 8 is not stationarily mounted, but instead fixed in a rotationally fixed manner to the holding brake 10, more precisely on the stationary part of the holding brake 10, which in the above-described manner passes through the Support 40 is supported against rotation.
- the advantage of the embodiment according to FIG. 3 is that both with the holding brake 10 closed and with the holding brake 10 open, the induced torque can be measured. Since the winch drive 8 is supported on the holding brake 10, the torque applied by the motor or winch drive 8 is likewise intercepted via the support 40 and measured by the associated torque sensor 21.
- the torque to be detected can also be measured directly on the free-fall brake 11 itself.
- the free-fall brake 11 can for this purpose rotatably mounted, but - as previously the holding brake 10 - are supported by a support 40 against rotation.
- the forces acting on the support 50 forces can be detected by means of a load cell, so that the arrangement of load cell and support 50 forms the torque sensor 21.
- the torque signal obtained at the free-fall brake 11 can be supplied to the governor 31 in an analogous manner as described above in order to regulate the operation of the free-fall brake in the desired manner and to actuate the actuating device 13 thereof.
- the holding brake 10 described above can also be arranged on the side of the free-fall brake 11.
- the motor shaft of the winch drive 8, the stationary or rotationally fixed, in particular can be attached to the bearing plate 6, and / or the input shaft of the transmission 9 is guided via a hollow shaft on the opposite side of the winch and there connected to the holding brake 10, see. Fig. 5.
- the holding brake 10 can be rotatably mounted in a similar manner as before in the embodiment of FIG. 2 and supported by a support 40 against rotation.
- the torque sensor 21 associated with the support 40 which may comprise, for example, the load cell shown in FIG. 5 (b), detects the load on the support 40 and thus the torque induced on the holding brake 10.
- the corresponding torque signal can be supplied to the controller 31 in an analogous manner, as described above.
- Fig. 6 shows a further embodiment, according to which a torque can also be measured on one of the two end shields 6 and 7, wherein in the drawn in Fig. 6 embodiment, the bearing plate 6, the torque sensor 21 is associated.
- the winch drive 8 and / or the holding brake 10 are rotatably mounted on said bearing plate 6, so that on the holding brake 10 and / or on the winch drive 8 induced torques on the bearing plate. 6 cause a corresponding reaction torque that can be measured by the torque sensor 21.
- the bearing plate in the manner shown in Fig. 6 (b) can be mounted to be pivotable and supported by a load cell and secured against rotation. More specifically, said load cell may be associated with one of the bearings to measure the acting load induced by a torque acting on the end shield 6.
- the torque signal provided by the torque sensor 21 in the form of the load cell shown can in turn be supplied to the controller 31 in the manner already described.
- Too high free-fall braking torque is detected and the free-fall brake is controlled.
- a support mode for pulling off the rope with manual force e.g. in handling work (engine drives when pulling off) can be set up.
