Definitions

  • the invention relates to a cable brake arranged in a carriage guided on a support cable for a traction cable guided through the carriage via deflection rollers or the like, the cable brake having a brake lever with a longer and a shorter lever arm which can be pivoted about an axis arranged in the carriage, in the carriage a stop cooperating with the shorter lever arm is arranged and the traction cable is passed between the stop and the shorter lever arm.
  • Such a cable brake is known from US-PS 42 62 811.
  • This known rope brake is opened or closed via the pull rope, an end stop being provided on the pull rope for this purpose.
  • this cable brake interacts with assigned brakes in the carriage which lock the carriage on the suspension cable.
  • Such devices are used for pre-delivering logs or the like, especially on slopes.
  • Devices are known in which the carriage is connected on one side to a return cable running parallel to the supporting cable, while on its other side the traction cable, which is guided via a rotatable deflection roller in the carriage, also runs parallel to the supporting cable.
  • the pull rope is first pulled out to the appropriate length, so that the log to be delivered or the like. can be reached. This pulling out of the pulling rope is particularly troublesome on slopes, since the pulling rope has a considerable weight.
  • the object of the invention is therefore to propose a rope brake of the type mentioned, which enables the pull rope to be pulled out and which automatically blocks the pull rope from running back in the pull-in direction.
  • the cable brake with the brake lever axis is arranged between two rollers for the traction cable in the carriage and the traction cable is guided over the end of the longer lever arm of the brake lever such that the traction cable acts on the traction cable section due to the shorter one Lever arm of the brake lever is pressed against the stop.
  • a rope pulley is advantageously rotatably arranged on the longer lever arm of the brake lever, over which the pull rope is guided.
  • the shorter lever arm preferably has a pressure thumb which interacts with the stop.
  • the pressure thumb preferably has an essentially flat, longer pressure surface for the traction cable, which extends approximately parallel to the stop in the pressure position.
  • the stop is advantageously arranged adjustable in the carriage.
  • the rope brake can preferably be switched on and off.
  • the brake lever axis is advantageously guided displaceably in a slot-like recess in the cable car and a shift lever is pivotally arranged on the brake lever axis and can be fixed in a latching device for switching on the cable brake.
  • the slot-like recess In its section assigned to the stop, the slot-like recess preferably runs at a distance and approximately parallel to the stop.
  • the latching device preferably has a latching bolt which is arranged in the cable car and which interacts with a recess in the shift lever.
  • a traction cable (4) is guided over two deflection rollers (9) in a carriage (L).
  • a slot-like recess (10) is provided between the two rollers (9), in which an axis (P) is slidably guided.
  • a switching lever (1) is pivotally arranged, which has a recess (11) at a distance from the axis (P), which can be latched into a locking pin (2) of the carriage (L), as shown in Fig 1 is shown.
  • a two-armed brake lever (3) with a longer lever arm and a shorter lever arm is also pivotably arranged on the axis (P).
  • the longer lever arm carries a rope pulley (5), while the shorter lever arm has a pressure thumb (6) with a longer, essentially flat pressure surface.
  • the shift lever (1) has a limit stop (12) for limiting the pivoting movement of the brake lever (3).
  • the pull cable (4) is guided over the deflection rollers (9) and over the ends of the two lever arms of the brake lever (3).
  • the slot-like recess (10) in its section associated with the stop (7) runs at a distance and approximately parallel to the stop, so that the axis (P) can absorb the forces that occur.
  • the rope can slide through the rope brake with a certain amount of friction.
  • the length of the two lever arms of the brake lever (3) is selected so that when the rope is pulled out in the direction indicated by arrow (A), the force acting on the shorter lever arm is so great that the force on the longer lever arm of the brake lever (3 ) acting force cannot lock the rope.
  • a carriage (L) with rollers is slidably guided on a tensioned supporting cable (14).
  • the carriage (L) is connected on one side to a return rope (R).
  • the traction cable (4) leads to the other side of the carriage (L) and is guided through the carriage via deflection rollers (9).
  • the pull rope must be pulled out in the direction of the arrow (15).
  • the traction rope with its free end on a tree (16) or the like is in the position of the carriage (L) designated (I). fixed and the rope brake placed in the braking position via the shift lever (1) (Fig. 1).
  • the cable car (L) is pulled with the aid of the return cable (R) in the direction of the arrow (17) into the position (11), so that the traction cable (4) is extended.
  • the rope (4) slides through the rope brake in the carriage. If the carriage is now stopped or returned to the position according to (I) contrary to the arrow labeled (17), the traction cable (4) is locked by the cable brake as described above.
  • the pull rope (4) then hangs loosely from the carriage (L), as shown in dashed lines in Fig. 3, and can be easily attached to the tree trunk to be moved. After releasing the rope brake by operating the shift lever (1), the back can be made in the usual way.
