Definitions

  • the invention relates to a clamp for detachable cable cars, with a fixed to the terminal housing and a movable jaw, which or the like by a spring, spring battery arranged in the terminal housing. is pressed against the rope, whereby the spring can be pretensioned by means of a switching lever, the arm of which is non-positively guided at the coupling point along a stationary coupling rail and, via a curve and a pressure roller that rolls on this, the switching movement of the lever caused by the coupling rail is non-positively on the movable one
  • the jaw transmits, the spring or spring battery surrounding a rod projecting from the movable jaw in the direction of its displacement is supported at one end on a flange of this jaw, the other end of the spring or spring battery being supported on a slide which is inside of the terminal housing is displaceably guided along the rod, the end of the slider facing away from the clamping jaws carrying the pressure roller and the switching lever being mounted directly on the terminal housing and having the curve whose course causes the coupling or uncoup
  • a clamp according to the generic term is known from US-A-3 257 966.
  • the switching arm is designed as a one-armed lever which is rotatably mounted on the terminal housing.
  • Two plates are attached to the switching arm, each of which is provided with an arcuate depression as a curve, on which the pressure roller engages.
  • Another lever with several locking elements is used to lock the switching arm, an additional control rail being required for this lever.
  • the locking device is thus complex.
  • a so-called knee-joint lever clamp which has an upper fixed clamping jaw and a lower movable clamping jaw, the latter being pressed against the rope by a spring-loaded toggle joint.
  • the clamping force test process or the coupling process is initiated via a roller arranged on the toggle joint, which is deflected by a control rail or coupling rail, the deflection of the roller being slight during the measuring process and greater during the coupling process. If the knee joint clamp is in the stable clamping position, the pretensioned peders exert the required clamping force on the movable clamping jaw via the knee joint lever.
  • the springs are compressed somewhat in accordance with the deflection of the roller.
  • the springs are compressed to a maximum by the greater deflection of the roller when the two levers forming the toggle joint are aligned in a line, which corresponds to an unstable position.
  • the toggle joint changes to the stable uncoupling position, the spring force again decreasing.
  • the object of the invention is to provide a new improved clamp for detachable cable cars, which does not have the disadvantages of the known type.
  • the arrangement of the two curves makes it possible to control the closing speed and the force at certain points in the movement sequence, i.e. where little force is required, the closing process can be quicker.
  • the two curves of the cam have a common tangent at the point of maximum force transmission, so that there is a constant transition between the curves.
  • the two curves of the cam are preferably designed as circular arcs with the same radius and the same center.
  • pivot axis of the two-armed shift lever is at a distance from the longitudinal axis of the spring or spring battery or the axis of the slider lying in the direction of displacement.
  • a further embodiment of the invention provides that the cam train associated with the coupling or uncoupling process is followed by an area of the cam assigned to the open position of the clamp, in which the distance from the cam surface to the pivot axis of the two-armed shift lever is a minimum.
  • 1 denotes the rope
  • 2 the fixed jaw and 3 the movable jaw.
  • the movable clamping jaw 3 continues in an expanded guide flange 4 and in a rod 5.
  • the guide flange 4 is slidably mounted in the upper part of a three-part cylindrical housing 6 in the longitudinal axis of the rod 5.
  • the fixed jaw 2 is also extended and screwed to the housing 6.
  • the rod 5 carries a spring battery 7, which is supported on the one hand on the flange 4 and on the other hand on a slide 8 which is slidably mounted both on the rod 5 and in the housing 6 in the longitudinal axis of the rod or the housing.
  • the slider 8 is designed as a hollow body so that the end of the rod 5, which is closed off by a nut 9, can be displaced in this cavity.
  • a pressure roller 10 is rotatably supported, which is supported on a cam or cam disk 11 which is mounted eccentrically to the longitudinal axis of the rod 5 in the lower part of the housing 6.
  • the cam 11 is rigidly connected to a clutch lever 12, which carries at its end a spherical roller 13 which is rotatably mounted about the axis of the clutch lever 12 and which is deflected during the measuring or coupling process via a clutch rail (not shown).
  • a return spring 14 causes the slider 8 to be brought into the lowest position in the open state of the clamp and thus also takes the movable clamp downward, thereby completely releasing the cable 1.
  • stops for the clutch lever 12 are provided in the form of two adjustable screw bolts 15, which are fixed by nuts 16.
  • the clutch lever 12 sweeps over an entire angular range of 90 °, the two end positions being shown in broken lines.
  • an essential feature of the invention is that the curve shape of the cam 11 in connection with the eccentric mounting of the cam enables the required or desired force profile during the coupling and decoupling process.
  • the curve shape of the jib 11 is adapted as required, the curve shape being adapted to any geometric curve such as e.g. a circular shape, an involute shape, etc. can be reproduced.
  • FIG. 3 shows the course of the clamping force F k as a function of the cam position or the angle of the clutch lever 12.
  • the cam 11 ' is designed in the shape of a circular arc with the same radius and the same center, which greatly simplifies the production thereof.
  • the other structure of this example is identical to that of FIG. 1.
  • the coupling lever 12 covers an entire angular range of 80 °, the two end positions being shown in broken lines. If the horizontal line is again taken as the reference line with 0 °, then + 40 ° corresponds to the opening position with minimal force transmission (FIG. 4a); the clamping process begins at + 20 ° ( Figure 4b); at -20 ° the clamping process is complete (maximum power transmission, Figure 4c), and at -40 ° the clamp is closed or the locking state is reached ( Figure 4d).
