Definitions

  • the invention relates to a construction hoist with a along a mast movable driving platform, the drive of which consists of a along a corner post of the mast running, with a pinion meshing rack and off a geared motor for the pinion provided with a brake, and with a depending on the travel one with the braking torque of the Brake actuated support spring adjustable contact for a circuit breaker of the gear motor.
  • the transmitted braking torque causes the spring support to travel, so that depending on the respective travel of the motor housing assigned circuit breaker can be operated in the event of an overshoot of the permissible torque load on the geared motor Spring travel to block the motor actuation by the overload switch.
  • a usual driving platform which is only in by the brake of the gear motor the respective driving position is kept along the construction lift mast, which on the motor shaft effective torque from the weight load of the driving platform depends, a corresponding with this known construction elevator Overload protection can be guaranteed.
  • the invention is therefore based on the object, a construction elevator of the beginning equip the type described with an overload protection so that with a comparatively low construction costs conventional units made from geared motors and brake can be used.
  • the invention solves this problem in that the geared motor a support sleeve, flanged through by the pinion shaft, is flanged, which is coaxial to the pinion shaft rotatable in a rotationally fixed to the driving platform Bearing housing and is supported by the support spring on the bearing housing, between the and the geared motor, the contact piece and the circuit breaker are arranged.
  • the derivative the braking torque does not take place via the non-rotatable motor housing, but via the non-rotatable bearing housing for the support sleeve on the driving platform, which is characterized by the geared motor and the brake formed unit with the support sleeve opposite the bearing housing the force of the support spring can twist.
  • the construction elevator shown in sections according to the embodiment has a three-sided mast 1, of which three corner posts 2 two one Form shift guide for a driving platform 3, using a travel drive 4 can be moved along this guide. To this end, contributes one of the corner posts 2 forming the guide for the driving platform 3 has a toothed rack 5, which meshes with a pinion 6.
  • the shaft 7 of this pinion 6 is as extended output shaft of a geared motor 8, which with a usual brake 9 is provided.
  • the shaft 7 of the pinion 6 is corresponding to the Fig. 3 on the one hand in a flange 10 of the gear part 11 of the gear motor 8 and on the other hand stored in a support sleeve 12, which itself in a bearing housing 13 is held rotatably.
  • This bearing housing 13 is via a mounting flange 14 screwed to the driving platform 3.
  • Support sleeve 12 On the gear part 11 facing, axially projecting over the bearing housing 13 end is Support sleeve 12 with a connecting flange 15 for the flange 10 of the bearing part 11 provided.
  • the connecting flange 15 of the support sleeve 12 is like the mounting flange 14 of the bearing housing 13 radially over the bearing housing 13, so that on these flanges 14 and 15 against each other in the circumferential direction offset, axially protruding support stops 16 and 17 attached can be between which a support spring 18 in the form of a Disc spring package can be supported As illustrated in FIGS.
  • the support spring 18 is received by a guide pin 19, the one hand the support stop 16 and on the other hand a guide approach 20 of the mounting flange 14 slidably penetrated.
  • This guide pin 19 is provided with a thickened end portion 21 on which the Support spring 18 finds an abutment, so that the thickened end portion 21 through the support spring 18 resting on the support stop 16 against the support stop 17 is pressed.
  • the pretensioning of the support spring 18 can thus be via an adjusting nut 22 can be set on a threaded portion of the guide pin 19 screw-adjustable seat.
  • the switching piece 24 is on a with the transmission part 11th connected mounting bolt 28 mounted screw adjustable, so that for the actuation of the overload switch 23 required travel of the geared motor 8 compared to the bearing housing 13 according to the respective conditions can be adjusted. If the platform 3 is overloaded, the Geared motor 8 around the shaft 7 of the pinion 6 in the dash-dotted line in FIG. 1 indicated pivoted pivoted, the switching piece 24 takes the in the Fig. 4 dash-dotted shift position in which the shift lever 26th is pivoted against its spring load with the effect that the Overload switch 23 blocks the actuation of the geared motor 8.
