Definitions

  • the invention relates to a winch device with a first winch with a first winch drum, which is rotatably driven by a first drive by a first drive, a second winch with a second winch drum, which is driven by a second drive by a second drive rotating, and a Synchronization device, by which a rotation of the first winch drum with a rotation of the second winch drum is synchronized.
  • twin winch devices with two winch drums and two separate drives are used in particular in cranes and other lifting devices.
  • a force distribution on at least two ropes is favorable for strength and safety reasons.
  • the use of two smaller drives instead of one large drive can bring advantages in terms of production and cost.
  • the use of two winch drums basically enables a joint and a separate actuation of the ropes, so that a high functionality is achieved by such a winch device.
  • a generic winch device is for example from the JP 52147849 A out.
  • the two winch drums are each driven by a hydraulic motor.
  • synchronization of the two hydraulic motors can be achieved.
  • even minor leaks in the hydraulic system can affect synchronization.
  • From the AT 309 011 B is a device for controlling the synchronization of at least two motor-driven wind works known, the synchronization is effected by means of a relay circuit.
  • electrical and electronic components may cause malfunction due to their sensitivity when used in construction machinery under harsh site conditions.
  • a transmission for the drive of two drum winches goes out of the DE 37 10 132 C2 out.
  • the two winch drums are driven by a common main drive motor, so that inevitably results in a synchronization.
  • a positioning motor With a positioning motor, a differentiated drive of the two drums can be achieved via an appropriate gearbox adjustment.
  • the invention has for its object to provide a winch device, which allows a particularly reliable synchronization of the two winch drives in a compact, simple structure.
  • the winch device is characterized in that a balancing shaft is provided with a first synchronous wheel and a second synchronous wheel, and that the first synchronous wheel is connected via a first rotary connecting device to the first drive and the second synchronous wheel via a second rotary connecting device to the second drive.
  • a simple and reliable mechanical synchronization of the two winch drums of the winch device is thus achieved.
  • the uniform speed of the two drives is determined by the balance shaft.
  • the balance shaft is an adaptation and equalization of different speeds of the two drive motors.
  • Elaborate hydraulic or electrical control devices can be omitted here.
  • the synchronizer may be a separate part or integrally formed with the balance shaft.
  • At least one coupling device is provided, with which a rotary connection of at least one of the drives to the balance shaft is releasable. If the coupling device is released, a differentiated drive of the two winch drums can take place. Only when a synchronized movement of the two drives is desired, the coupling device can be actuated and thus carried out via the balance shaft, a speed and / or torque adjustment.
  • a particularly advantageous embodiment according to the invention is that at least one of the synchronizing wheels is rotatably mounted on the balancer shaft and that the rotatably mounted synchronous wheel by the coupling means rotatably connected to the balancer shaft.
  • the coupling device is inventively provided on the balance shaft.
  • a frictional rotary connection takes place, for example, by a clutch disk arrangement, whereby a correspondingly slow speed adjustment without torque impacts is made possible by a slow actuation, for example by pneumatically or hydraulically actuated actuators.
  • the rotary connection device may in principle be a gear arrangement or a chain. According to the invention, it is advantageous that the rotary connection device comprises a drive belt.
  • This drive belt may have a flat, V or poly-V profile, but this is preferably a toothed belt.
  • the transmission of the two wind turbines are designed as a reduction gear.
  • a high speed of the output shaft of the drive is reduced to a lower speed for rotating the winch drum, resulting in a corresponding increase in torque.
  • the balance shaft is driven via the rotary connection devices in each case directly via a respective output shaft of the drives. The speed adjustment thus takes place directly between the rotational speeds of the two output shafts at relatively low torques. This allows a compact arrangement and design of the balancing shaft and the coupling device.
  • a particular compact and high reduction ratio is achieved according to the invention in that the first gear and the second gear has at least one, preferably three planetary gear stages.
  • the planetary gear stages of two wind turbines are preferably constructed identically with the same reduction ratio, so that when speed adjustment, the balancer shaft, the two wind drums are driven at the same speed and the same torque.
  • the compact design of a winch device according to the invention is further supported by the fact that the drive shaft and the winch drum are arranged coaxially to one another in each winch.
  • the winch drum is designed as a hollow cylinder, in the interior of which the transmission is arranged and the drive shaft protrudes.
  • a particularly compact arrangement with good symmetrical power distribution is achieved according to the invention in that the drive shafts and the wind drums are directed parallel to the balance shaft and that the balance shaft is arranged centrally between the two wind drums.
  • a mirror-symmetrical arrangement of the two wind turbines to a center plane through the balance shaft ensures a reliable compensation of lateral forces on the balance shaft. This is also advantageous for a simple and compact construction.
  • a further preferred embodiment of the winch device is that for driving the balance shaft, a first extension shaft, which is rotatably connected to the first drive shaft, and a second extension shaft are provided, which is rotatably connected to the second drive shaft, and that the first extension shaft and the second extension shaft protrude from a housing for mounting the winch drums.
  • a conventional winch for the invention can be easily adapted.
  • the extension shafts protrude out of a storage housing of the wind drums, so that a rotational connection with the balance shaft on the outside of the housing can be formed in a simple manner.
  • a cost and manufacturing advantage results according to the invention in that the first winch and the second winch are constructed identical.
  • a winching device 10 has a box-shaped housing 12 which is open at the top and in which a first winch 20 and a second winch 40 are arranged parallel to one another.
  • a first winch drum 22 and a second winch drum 42 are rotatably mounted in the housing 12.
  • a synchronization device 60 with a balancing shaft 62 is arranged in the middle between the two windworks 20, 40.
  • a first synchronous 64 and a second synchronous 66 are arranged on the balance shaft 62.
  • the first synchronizer 64 which is rotatably connected to the balancer shaft 62, via a belt-shaped, toothed drive belt 28 in rotation with a first drive wheel 27.
  • This first drive wheel 27 is rotatably mounted on an extension shaft 32, which via a hydraulic first drive 26 of the first windmill 20 is driven.
  • a second extension shaft 52 of the second winch 42 is driven by a hydraulic second drive 46 of the second winch 40.
  • a second drive wheel 47 is non-rotatably mounted, which is rotatably connected via a second drive belt 48 to the second synchronous 66 on the balance shaft 62.
  • the balance shaft 62 is about shaft bearings 63 rotatably mounted relative to a bearing sleeve 14, which is fixedly mounted on the housing 12.
  • the first synchronous wheel 64 is connected via a rotationally fixed connection 65 fixed to the balance shaft 62.
  • the second synchronous wheel 66 is rotatably mounted on the balance shaft 62 via pivot bearings 67. Via a coupling device 70, the second synchronous 66 can be rotatably connected to the balance shaft 62, so that a synchronous rotation between the first synchronous 64 and the second synchronous 66 is achieved.
  • the coupling device 70 includes a first coupling element 72 with clutch plates, which is connected via bolts fixed to the second synchronous 66.
  • This first coupling element 72 is rotatable relative to the balancing shaft 62 together with the second synchronizing wheel 66.
  • a second coupling element 74 with clutch plates rotatably connected to the balance shaft 62.
  • Via a fluid supply 78 and fluid channels 76 in the balance shaft 62 an actuation of the coupling device 70 can take place.
  • a relative displacement of the second coupling element 74 takes place axially with respect to the first coupling element 72, so that they are positively connected to one another via their respective clutch plates.
  • This frictional connection creates a rotationally fixed connection between the second synchronous 66 and the balance shaft 62 via the second coupling element 74 which is rotatably but axially displaceable on the balance shaft 62 is arranged.
  • the schematic structure of a winch is according to Fig. 4 shown on the first winch 20.
  • the first winch 20 has a first winch drum 22 for operating a schematically illustrated rope 16.
  • a drive shaft 30 is driven via a first drive 26, which is a hydraulic drive.
  • the drive is at high speed with low torque.
  • About a non-illustrated planetary gear assembly, the speed is reduced, and the corresponding amplified torque is transmitted to the first winch drum 22 in a known manner.
  • An axis of rotation 31 of the drive shaft 30 is coaxial with the axis of rotation of the first winch drum 22.
  • a first extension shaft 32 rotatably mounted on the drive shaft 30 is attached. Via the extension shaft 32, which extends the first drive shaft 30 axially outward from the housing 12, the first drive wheel 27 is driven. The first drive wheel 27 is rotatably mounted at the free end of the first extension shaft 32.
  • the first wind work 20 is identical to the second wind work 40, except for the arrangement of the second drive wheel 47, which is axially offset from the first drive wheel 27 of the first wind work 20 is formed. This axial offset of the second drive wheel 47 is shown schematically in FIG Fig. 4 represented by the direction indicated by dashed line arrangement of the second drive wheel 47.
  • the first extension shaft 32 and the second extension shaft 52 are identical and each have a receptacle for both drive wheels 27, 47.
  • the coupling device 70 is not actuated to produce a frictional connection, the first winch 20 and the second winch 40 can be driven independently. However, if it is necessary for a jointly coordinated lifting movement, to operate the two wind power plants 20, 40 at the same speed; the coupling device 70 is actuated. As a result, now the second synchronous 66 is rotatably coupled to the balance shaft 62 with this. In this way, the rotational movements of the first extension shaft 32 and the second extension shaft 52 are forcibly mechanically coupled together. Via the balancer shaft 62 and the drive belt 28, 48 designed as a toothed belt, a rotational speed adaptation takes place between the first winch 20 and the second winch 40. In this way a synchronization of the two windmills 20, 40 is ensured in a reliable mechanical manner.
  • the synchronizing wheels 64, 66 and the two drive wheels 27, 47 are designed as toothed rollers, which are preferably the same.
