Definitions

  • the invention relates to an operationally releasable clamping device, in particular for cable orbits, with at least one clamp comprising the rope by means of two jaws, at least one jaw being able to be pressed against the rope by at least one compression spring or by means of a preferably pivotable lever that runs against a stationary rail can be lifted off, as well as with at least one test spring, which counteracts the compression spring, and with a device, which measures the deformation of the test spring when the jaw is clamped on the rope and, if a predetermined value is exceeded, triggers a signal and / or stopping device to respond.
  • the deformation of the test spring is a measure of the force of the compression spring causing the clamping. This force can decrease over time both due to the aging of the compression spring or due to the breakage of individual elements of the same as well as due to the wear of the movable connections between the compression spring and the jaw.
  • the stationary rail is supported by a spring which is compressed by the force of the roller of the lifting mechanism which runs onto the rail. If this force falls below a predetermined value, this spring is no longer compressed or is compressed only incompletely, as a result of which this suspension is prevented from continuing to travel.
  • a disadvantage of this device is that it is sensitive to pivoting movements of the hanger, so that incorrect switching can occur due to dynamic influences. Furthermore, the force of the pressure spring is measured in the disconnected state, while the force when the hanger is clamped is decisive for the safety of the clamping.
  • the aim of the invention is to provide a clamping device with a To create a test device for the clamping force, through which the clamping force of the jaws is checked in the clamped state unaffected by movements of the hanger and regardless of its speed. According to the invention, this is achieved in that the test spring is arranged in the pressing mechanism.
  • FIG. 1 shows a longitudinal section through a clamping device according to the invention, the parts being drawn in the position in which they are with sufficient force of the compression spring assembly with the jaw pressed against the rope.
  • 2 also shows in longitudinal section the position of the parts with insufficient clamping force.
  • FIGS. 3 and 4 each show a variant in a detail
  • FIG. 5 shows a modified form of the test spring for this.
  • the hanger of the lift has at its upper end a pipe section 2 which is rotatably mounted about an axis 3 in order to enable pendulum movements in the "direction of travel.
  • the axis 3 is inserted in a terminal box, which consists of a U-shaped part 6 and two end plates 7 and 8 consists. At 9, a role of the running gear and the corresponding travel rail are indicated, with which this is supported when the chair is released from the rope.
  • the fixed clamping jaw 10 is fastened to an extension of the terminal box.
  • the movable clamping jaw 11 is rotatably mounted about a bolt 12. At its end facing the terminal box, it is articulated by means of a bolt 13 to an obliquely arranged pressure piece 14, which in turn is connected by means of a bolt 15 to a rod 16 which is mounted in the terminal box in a longitudinally displaceable manner.
  • a plate spring assembly 18 At a shoulder 17 of this rod there is a plate spring assembly 18 which tries to push the rod 16 in the direction of the clamping jaws, so that the movable clamping jaw 11 is pressed against the cable 19 via the pressure piece 14.
  • the geometry and the spring force are chosen so that there is approximately three times the security against slipping under the most unfavorable conditions.
  • the rod 16 is moved against the force of the spring assembly 18. This is done by means of a rotatably mounted lever 20 which is connected at one end to the rod 16 by a tab 21 and at its other end carries a roller 22 which runs onto a rail, not shown, in the station.
  • the compression springs 18 and the test springs 14 are supported. accordingly, together on an abutment, which is formed by the sleeve 23.
  • the total force of these test springs 24 is chosen so that it is slightly less than that of the spring assembly 18 when the lower tolerance limit of the spring force is reached. If the force of the spring assembly 18 is smaller than that of the test springs 24 when the hanger is clamped to the rope 19, the sleeve 23 thereby moves in the direction of the rope 19, as shown in FIG. 2.
  • the size "x" of the displacement is a measure of the falling below the required spring force.
  • this shift exceeds a predetermined level, this causes the system to be switched off and / or a signal to be emitted.
  • a rod-like extension 25 is attached to the sleeve 23, which rotates a shift lever 26.
  • a stationary switch 27 is attached, which is actuated by a rotatable switching element 28. This is arranged so that with sufficient force of the spring assembly 18, the shift lever 26 moves past the switching piece 28 (Fig. 1).
  • the force of the spring assembly 18 has decreased so much that the test springs 24 have shifted the sleeve 23 to a certain extent, the shift lever 26 is rotated downward and it abuts the contact piece 28 the system is switched off and / or a signal is triggered.
  • the abutment 23 has on its side facing away from the compression spring 18 on a circular ring arranged conical depressions 29 'for receiving balls 30, which are held at a distance by a cage 31 and attached to each other Support a pressure plate 32, which also has recesses 29 "corresponding to the balls 30.
  • the pressure plate 32 is rotatably supported by means of an axial bearing 33 via a bushing 34 on the end plate 7 of the terminal housing the end plate 7.
  • the abutment 23 is secured against rotation by means of a transverse pin 35 and an elongated hole 36 in the rod 16. However, it can move in the longitudinal direction, just as in the embodiment according to FIGS Coupling not shown here and a stop attached.
  • test spring 24 is biased so much that it is unable to rotate the pressure plate 32 with sufficient force of the compression spring 18. However, if the force of the compression spring drops below the predetermined value, the balls 30 snap out of the recesses 29 'or 29 "by rotating the pressure plate 32 and the abutment 23 is displaced axially, as a result of which the coupling piece 25, the stop 26 and the actuator 28 of the switch 27 is activated.
  • the compression spring including the abutment can be rotatably mounted, so that an anti-rotation device can be omitted.
  • the compression spring is not supported directly at its end facing away from the abutment 23, but via an axial bearing 33 on the rod 16.
  • the pressure plate 30 is supported on the end plate 7, being secured against rotation in a manner not shown, for example by a pin.
  • the coupling piece 25 is designed so that it allows rotation of the abutment 23; for example, it can slide against it.
  • the ends of the test spring 24 engage in corresponding bores in the abutment 23 or in the end plate 7.
  • test spring 24 can also be designed as a helical spring, which is located on the one hand on the U-shaped part 6 of the terminal housing and on the other hand on an extension 37 of the pressure plate 32 (embodiment according to FIG. 3) or Abutment 23 (execution according to FIG. 4) is supported.
  • a plurality of test springs distributed over the circumference are preferably arranged.
  • the sleeve could not be moved mechanically, but electronically, optically, magnetically etc. on the stationary one. Switches are transmitted.
  • the test spring could also be designed as a plate spring package, which would, however, increase the required length.
  • the implementation of the principle according to the invention is not limited to a clamp with only one movable jaw; it can also be used with two movable jaws and in gondola lifts with double clamps.
