Definitions
- the invention relates to a method for operating a winch, one on a powered reel wound rope fed to at least one capstan head and around this is looped, with a capstan drive the capstan head turns and due to rope friction between rope and capstan head generates the rope feed.
- the invention further relates on a corresponding winch.
- Winches of this type are used, for example Piste grooming devices used as climbing aids to climb steep To be able to climb slopes.
- the rope is one or more times around the capstan head (s) and is looped by the Reel drum retracted. Due to stiction as a result of The rope is wrapped around the capstan heads by turning the capstan drive of the vehicle.
- the reel and the capstan head is equipped with a hydraulic motor, which is operated by a common hydraulic pump are driven. So that is ensures that the rope when driving the capstan head is continuously taken up by the reel and at the same time the required wrapping of the capstan head is maintained.
- a hydraulic motor which is operated by a common hydraulic pump are driven. So that is ensures that the rope when driving the capstan head is continuously taken up by the reel and at the same time the required wrapping of the capstan head is maintained.
- there are problems result in the reel winding.
- the rope gets very tight the reel is wound up and it can happen that Rope when winding between two turns of a lower one Rope crimped.
- the invention has for its object the generic To improve the process or the associated winch, that the rope can be easily wound on the reel and an effective rope feed for the winch at the same time allows a good drive, with the winch as possible should be easy and safe to use.
- the reel drive on the function of winding or unwinding of the rope can be optimized so that the Rope can be easily picked up on a reel.
- the capstan drive according to the required tractive force or Driving force of the vehicle can be optimized.
- the Reel drive ensures sufficient rope tension to ensure that the wrapping of the capstan necessary for driving maintain.
- the reel can be particularly advantageous according to the required tension of the rope between reel and Capstan head are driven. This allows an optimal Reach traction between capstan and reel. she can be coordinated so that sufficient for propulsion There is static friction on the capstan head and sufficient tension for orderly winding of the rope on the reel is available stands.
- the resilience can be below a critical Area are kept, if exceeded there are problems would give with the winding.
- the resilience can for example at about 700 N, which for winds of Snow grooming equipment is a suitable value.
- the displacement volume can connected to a hydraulic motor driving the reel Hydraulic pump depending on the load condition of the hydraulic motor be adjusted.
- This allows the reel to be driven very good for an optimal tension of the rope between Optimize reel and capstan. If it increases too much
- the displacement volume can be reduced with rope force, so that the tension does not increase any further.
- When slack sagging rope can increase the displacement be so that the rope quickly and to the optimal tension is wound up.
- the load state of the Hydromotor each by the from the reel drum on it transferred resistance.
- With the help of the hydraulic pump can appropriate adjustment of the drive of the hydraulic motor optimal be adjusted or regulated.
- the load pressure in one between the Reel driving hydraulic motor and the one driving it Hydraulic pump provided high pressure line at different Load conditions are kept essentially constant.
- the drive power can at Hydropump very good only by adjusting the Displacement volume can be varied.
- the regulation of Reel drive can be switched on separately. This is special when starting the system advantageous because the adjustment or the control must only be switched on when the Rope operation starts. Before that, e.g. a low stand-by pressure can be set. Not until actual winch operation can be switched on by the Reel drive a regulation with the required Use operating pressure to achieve the required Ensure minimum torques.
- the capstan drive regardless of the reel drive according to the required rope feed can be controlled. So that can the desired driving force or driving speed of the Control capstan drive separately, so that on the reel drive no consideration has to be taken. He turns himself over independently accordingly. You can push yourself of the winch drive so focus on propulsion.
- the displacement volume from one to the other is conceivable Hydraulic motor connected to capstan driving hydraulic motor with the help and separate control of the by the Hydraulic pump generated load pressure can be changed. So can the load pressure can be used to control the pump. Of the Load pressure can then be corresponding in a branch line can be varied and adjusted accordingly same pump can be used.
- a reel brake and a Capstan brake when starting the winch drive at the same time be solved. This means that the reel and capstan head are retired locked by the brakes and only when starting the They are released by the winch drive, at the same time the corresponding torques the rope jacking and the Insert rope winding. When the winch drive is stopped, For example, both brakes can intervene again that the rope between capstan and reel is optimal for the next use remains excited.
- the brakes can be dependent an operating pressure in a hydraulic line of the Reel drive are operated.
- the brakes are optional can only be released when an operating pressure in the reel drive is exceeded, so that the reel is only released if there is already sufficient torque to Maintaining the rope tension on the reel drive.
- the operating pressure serves as a regulation for sufficient Torque.
- the reel brake or also the capstan brake when the operating pressure falls below tight again so that the rope is held in tension becomes.
- the brakes may not be released until after torque is applied to the reel. With that the Reel drum loosened and is already at the moment of loosening the right torque for winding and for rope tension to disposal.
- the capstan drive blocked when changing the rope. So that is ensures that the rope advance when changing the rope stands still.
- the generic method described at the outset can be made possible, for example, by a generic Winch with a reel driven by a reel drive, can be wound up and unwound on the rope, the rope of the Reel can be fed to and around at least one capstan head is loopable, and a capstan drive turns the capstan head and the rope due to rope friction with the capstan head advances.
- the reel and capstan can be hydraulic be driven, the reel driving a driving Reel motor with its own reel pump and the capstan head one own driving capstan motor with its own capstan pump having. So that the two hydraulic circuits with Motor and pump ideal for the desired purpose be designed. This also simplifies the constructive Designing the elements as they are for each Purpose can be selected. Pump and hydraulic motor can according to the required pressures and Volume flows can be optimally selected.
- the reel pump can be adjustable, but that Adjusting the pump to one depending on the Regulating circuit load state of the reel motor is motion-coupled.
- the Reel pump according to the load state of the reel motor be adjusted so that the required rope tension or the torque has a regulating effect on the reel pump.
- the displacement volume can be corresponding be adjusted.
- the control loop may have a switch be switchable. This means that the regulation can be selected be switched on if necessary, e.g. if the Capstan drive is actuated.
- the load pressure in a between the reel pump and Reel motor provided high pressure line essentially be constant.
- the capstan pump can be particularly advantageously adjustable, the actuator of the pump with an outside separately controllable control circuit is motion-coupled. over the separate controller can control the displacement of the Capstan pump can be adjusted so that the capstan drive is set accordingly.
- a reel brake and a cap brake can be provided.
- reel brake and cap brake be solvable together. They can be released though sufficient drive torque for capstan head or reel for the Propulsion or the tension and winding force is available.
