Definitions

  • the present invention relates to a descender with a cable inlet and a cable outlet for a safety rope with a pulley and a brake device for the sheave, wherein the brake device is arranged on the same shaft as the pulley, and wherein additionally at least one friction brake is arranged and designed in this way that the friction brake directly cooperates with the safety rope cooperatively by means of a frictional engagement, according to the preamble of claim 1.
  • the brake device includes a centrifugal brake device with weights that are in turn vulnerable and a wing pump type or transmission pump type oil hydraulic brake device.
  • the oil hydraulic brake device is connected to the pulley via a clutch and the centrifugal brake device is connected to the pulley via a planetary acceleration gear.
  • the brake device and the pulley are arranged on a common shaft.
  • a Notabseil worn which has a centrifugal brake, which is connected to a pulley. At the cable inlet and cable outlet each an additional brake shoe is arranged. A rope winds around the sheave and with increasing speed of the rope the centrifugal brake exerts an increasing braking force.
  • a Notabseil noticed is known in which a pulley is connected to a carrier for weights. The weights are pivotally mounted on the carrier and upon rotation of the carrier, the weights of the centrifugal force are pressed radially outward. As a result, brake shoes are pressed against a fixed brake disc. At the cable inlet and rope outlet rotatable rollers are arranged as a guide for a rope. However, these have no braking function.
  • a rescue and sliding device in which by means of a manually operable lever, a rope sliding through it is more or less clamped, so that there is a more or less strong braking effect on the rope.
  • This device can for example be hung firmly and hanging on the rope person can be slowly drained by another person by pressing the lever.
  • guide rollers are arranged on a cable inlet. A frictional force on the rope is exerted only by the lever with associated clamping parts.
  • the guide rollers serve only the function "guidance”.
  • a friction brake by means of the guide rollers is not apparent from EP 163 938 A1.
  • a sheave, around which the rope loops, and a braking device for these are not disclosed.
  • the invention is based on the object, a Abseilvorraum og. To improve the type of functional reliability and manageability.
  • the friction brake has at least three fixed bolts, which are arranged such that the safety rope threads around the bolts and rests on all bolts.
  • the brake device comprises a centrifugal clutch and / or an oil-hydraulic brake.
  • the friction brake is only located at the cable outlet.
  • Fig. 1 shows a preferred embodiment of a descender according to the invention in a schematic side view and Fig. 2 in a schematic sectional view.
  • the brake device is, for example, a centrifugal clutch or an oil-hydraulic brake.
  • a safety cable 16 runs around the sheave 10 essentially without slip, so that the braking device 12 keeps a speed of movement of the safety cable 16 by the abseiling device below a predetermined value and substantially constant.
  • the present abseiling device is therefore one in which the safety rope runs through the abseiling device fixed at one point, without being wound up or unwound in or from the abseiling device.
  • an additional friction brake 20 for the safety cable 16 is additionally provided on one side of the sheave 10, at which the safety cable 16 moves out of the abseiling device or away from the sheave 10 (the direction of movement of the safety cable 16 is indicated by arrow 18) arranged.
  • This friction brake 20 comprises, in the illustrated exemplary embodiment, three fixed bolts 22 around which the safety cable 16 threads, so that it bears against all the bolts 22.
  • the bolts 22 are arranged such that their respective longitudinal axes 20 lie on a line. Due to the frictional engagement of the securing cable 16 on the bolt 22, a part of the forces occurring is absorbed by this friction brake 20 and thus the cable pulley 10 or the braking device 12 is relieved.
  • the reference numeral 26 is a cable outlet and 28 is a cable inlet designated.
  • the safety rope moves when abseiling a person in the direction of arrow 18, so that the safety rope 16 at the cable outlet from the abseiling out or away from the sheave 10 and when Seileinlauf 28 in the abseiling device or to the sheave 10 moves towards.
  • the friction brake 20 is arranged on the cable outlet.
  • a friction brake is provided, wherein both friction brakes are then designed such that the friction brake on which the safety rope moves into the abseiling device, the safety rope is free and that friction brake in which the safety rope moves out of the abseiling device, the safety rope is subjected to a frictional force.
  • the abseiling device acts on both sides and irrespective of the direction in which the safety rope runs around the sheave, that is to say, for example, even when the safety rope moves in the direction opposite to arrow 18 relative to the abseiling device.

Abstract

L'invention concerne un dispositif de rappel comprenant un point d'amenée de corde (28) et un point de sortie de corde (26) pour une corde de sécurité (16), ledit dispositif comprenant un disque (10) pour la corde et un dispositif de frein (12) pour le disque (10). Le dispositif de frein (12) est placé sur le même arbre (14) que le disque (10) pour la corde. Au moins un frein à friction (20) est également disposé et inséré sur le dispositif de rappel, de manière à ce que le frein à friction (20) interagisseant directement avec la corde de sécurité (16) freine cette dernière par liaison de friction.
