Definitions

  • the invention relates to a brake safety device in interaction with a free leg of a guide rail catching roller in the wedge gap and brake plate for braking until an elevator car or a counterweight comes to a standstill.
  • a brake safety device with a guide wedge and a counter shoe which are guided along a free leg of a guide rail during normal operation.
  • the guide wedge is rotatably supported at the lower end by means of a guide pin and is held at the upper end by an adjustable spring assembly.
  • a roller bracket is deflected upwards.
  • a catch roller is moved upwards over the support from the rest position along the edge of the guide wedge.
  • the guide wedge is swung out to the right and the spring assembly is put under tension.
  • the upward movement of the catch roller is limited by a brake wedge arranged at the upper end of the catch wedge.
  • a disadvantage of the known device lies in the large mechanical structure of the rotatably mounted guide wedge and the spring assembly acting on the upper end of the guide wedge. Another disadvantage of the known device is that additional commissioning work on the spring assembly and the brake wedge is essential before start-up and after a malfunction.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of avoiding the disadvantages of the known device and of designing a brake safety device in such a way that a brake safety delay that can be adapted to different total weights of the elevator car or counterweight is feasible with fewer individual parts.
  • 1 denotes a housing with a recess 2 extending on the front of the housing over the entire height of the housing, at one end of which a brake plate 3 is arranged, next to which a free leg 4 of a guide rail 5 is immersed.
  • a trapezoidal bracket 6 with a rectangular extension 7 protruding from the housing 1 is inserted into the part of the recess 2 adjoining the leg 4.
  • the bracket 6 has on the guide rail side an obliquely upward-extending link 9 which forms a wedge gap 8 and has a U-shaped cross section, which merges into a circular end at the top and bottom.
  • the two end faces of the link 9 serve as runways 10 for roller axles 12 arranged on a cylindrical catch roller 11 knurled on the surface of the jacket.
  • a screw 16 is connected to the housing 1 arranged on a carrier 17, the other end of the screw 16 is connected to a tab 21 arranged on the extension 7.
  • a height adjustment A of the extension 7 effected by means of the screw 16 results in a transverse adjustment B of the bracket 6.
  • the distance between the catching roller 11 and the free leg 4 in turn determines the distance to be adapted to different total weights of the elevator car and the counterweight Brake delay as well as the deflection of the bracket 6, designated C.
  • a speed limiter (not shown) actuates a lever mechanism, designated 19, by means of traction elements, which is connected to one end of an actuating arm 20 which plunges into the recess 2.
  • the catch roller 11, which is rotatably arranged at the other end of the actuating arm 20, is deflected from its rest position and pulled upwards in the wedge gap 8, the roller axes 12 rolling off the path predetermined by the roller tracks 10. Due to the upward relative movement along the runway 10 of the catching roller 11, the brake plate 3 becomes the free leg 4 the guide rail 5 brought into engagement. About the resilient bracket 6, the catch roller 11 is pressed more and more against the free leg 4 without internal friction losses and the elevator car or the counterweight is braked to a standstill.
