Definitions

  • the invention relates to a winch specified in the preamble of claim 1 genus.
  • the winch From the DE 195 12 103 C2 is a winch with a rope drum known.
  • the winch has torque sensors, which are arranged in the interior of the cable drum on the outer circumference of a cup-shaped receptacle for the drive motor.
  • torque sensors To replace the torque sensors, a bearing support and the entire drive motor must be disassembled from the cable drum. This is very expensive, so that repair or replacement of a torque sensor associated with high costs.
  • the EP 1 308 414 A1 discloses a winch according to the preamble of claim 1, the drive motor is arranged in a support member.
  • the support member is mounted on a bearing support with play in the circumferential direction. Relative movements between the carrier component and the bearing support are determined via load receiver.
  • the US 3,330,154 discloses a cable drum, on whose bearing shaft a load receptor is arranged.
  • the DE 297 23 821 U1 discloses a winch whose drive is connected via a torque arm with the frame of the winch is.
  • the torque arm has a measuring device for determining the force applied to the cable.
  • the EP 1 602 617 A1 shows a hoist with a lifting gear on which a sensor is arranged, which detects the deformation of the shaft, which is caused by the lifting load.
  • the DE 85 20 140 U1 discloses a winch whose transmission housing is supported by a torque arm.
  • the torque arm has strain gauges to measure elastic deformation.
  • the invention has for its object to provide a winch of the generic type, which allows easy replacement and easy repair.
  • the transducer can be replaced by replacing the component in a simple manner.
  • the component is arranged so that it is interchangeable without disassembly of a bearing support.
  • the cable drum must not be opened so that the exchange can be carried out by the user himself in a simple manner.
  • the component on which the pickup is arranged is interchangeable, it is easily possible to retrofit a winch with a pick-up for detecting the load.
  • winches can be built with facilities for load detection identical construction with winches without load detection. Only the component on which the pickup is arranged, in each case adapt and optionally equipped with a pickup. Because the sensor is not arranged on the bearing support itself, deformations of the bearing support are not included in the measurement of the load, so that a more accurate measurement result can be achieved.
  • the component extends through the bearing support.
  • the transducer has a connection line for connection to a controller, wherein the connection line is guided by a trained in the component channel from the winch.
  • the lead is thus integrated into the component, so that the replacement of the component with the transducer can be performed very easily and quickly.
  • the position of the component is secured to the bearing support with securing means which are accessible from the outside of the bearing support facing away from the cable drum.
  • the component consists of a different material than the bearing support.
  • the bearing support consists in particular of a casting material, preferably of gray cast iron.
  • Cast iron bearing supports can be manufactured in a simple way and absorb the forces occurring during operation. For the arrangement of pickups for load detection gray cast iron is only poorly suited.
  • the component may be made of a material that is well suited for the placement of a pick-up, such as steel. Characterized in that the transducer is arranged on a separate from the bearing support member, the material of the component can be adapted to the requirements of the transducer.
  • the cable drum is mounted on both sides of bearing supports. This results in a high stability and low bending forces.
  • the drive motor is held on a bearing support and the transmission is supported on the opposite bearing support. It is envisaged that the transmission is supported on the bearing support via the component on which the sensor for detecting the load is arranged. Via the gear, the forces acting on the cable drum forces are transmitted into the component, so that the deformation of the component is a measure of the force acting on the cable drum force.
  • the component is designed as a bolt.
  • the transmission is in particular a planetary gear whose planet gears are mounted on a stationary planet carrier.
  • the planet carrier is rotatably connected to the bolt.
  • the rotationally fixed connection is in particular designed so that it allows movement of the bolt relative to the planet carrier in the direction of the drive axis of the cable drum. As a result, the bolt can be pulled out of the planet carrier in the direction of the drive axle.
  • the planet carrier is rotatably connected to the bolt via a toothing, in particular via a serration. A toothing allows the transmission of high torques and at the same time a nesting of the two components in the direction of the drive axle.
  • the bolt is rotatably connected to the bearing support.
  • the rotationally fixed connection is designed so that it allows movement of the bolt relative to the bearing support in the direction of the drive axis of the cable drum.
  • the bolt can also be pulled out of the bearing support in the direction of the drive axle. Due to the non-rotatable connection with bearing support and planet carrier via a respective toothing a simple interchangeability of the bolt is given.
  • the bolt has a circumferential groove in which the sensor is arranged to detect the load.
  • the circumferential groove is in particular the narrowest cross-section of the bolt.
  • the pin is rotatably connected in a first region with the bearing support and in a second region rotatably connected to the planet carrier, wherein the circumferential groove between the first and the second area is arranged.
  • the circumferential groove, in which the transducer is arranged thus lies in the region in which the torque is transmitted from the planet carrier to the bearing support.
  • a transducer for detecting the load is a strain gauge.
  • strain gauges are provided, wherein two pairs of strain gauges are disposed opposite to each other on the circumference of the circumferential groove. Each two strain gauges of a pair are offset by 90 ° to each other, so that the strain signals are recorded in mutually perpendicular directions.
  • winch 1 has two bearing supports 3, 4, between which a cable drum 2 is arranged.
  • the cable drum 2 is rotatably mounted about a drive shaft 30.
  • a cable 5 is wound, which is up or unwound on rotation of the cable drum 2 about its drive axis 30 depending on the direction of rotation.
  • the cable drum 2 is mounted on the bearing support 3 with a bearing 7 on a projecting into the cable drum 2 collar 32 of the bearing support 3.
  • a seal 19 is arranged to the bearing support 4. towards the interior 6 of the cable drum 2 is open.
  • a pot 11 is formed, which projects into the interior of the cable drum 2 and on the outer circumference of a bearing 8 is arranged, on which the other end of the cable drum 2 is supported.
  • a drive motor 9 is arranged, which drives a drive shaft 10 in rotation.
  • the pot 11 is partially closed by a disc 29.
  • On the disc 29 of the drive motor 9 is screwed.
  • the disc 29 has a central opening through which the drive shaft 10 protrudes.
  • the drive motor 9 drives the cable drum 2 via a gear 12, which is designed as a planetary gear.
  • the sun gear 13 of the planetary gear is fixed in rotation on the drive shaft 10.
  • the sun gear 13 drives planet gears 14, of which in Fig. 1 two are shown.
  • four planet gears 14 may be provided.
  • the planetary gears 14 are rotatably connected to the bearing support 3 about the drive shaft 30.
  • the planetary gears 14 are rotatably mounted on bearing axles 15.
  • the bearing shafts 15 are fixed to a planet carrier 16 which is rotatably connected to a bolt 18.
  • the bolt 18 is rotatably mounted on the bearing support 3.
  • the planet carrier 16 is thus rotatably mounted relative to the bearing support 3.
  • the cable drum 2 has on its inner circumference in the region of the planet gears 14, a toothing 17, with which the planet gears 14 are engaged.
  • a rotation of the sun gear 13 causes a rotation of the planet gears 14 about the bearing axes 15. Since the bearing axes 15 stationary are arranged, the cable drum 2 is driven in rotation by the rotation of the planet gears 14.
  • Fig. 2 the design of the bolt 18 is shown in more detail.
  • the bolt 18 has at its inside of the cable drum 2 projecting end a toothing 20 which cooperates with an internal toothing 22 of the planet carrier 16.
  • About the teeth 20 and 22 of the bolt 18 and the planet carrier 16 are rotatably connected to each other.
