Definitions

  • the invention relates to an elevator system at the top Drive unit arranged at the end of an elevator shaft with traction sheave for the drive by means of ropes one in Elevator shaft on elevator car guided by guide elements with counterweight.
  • Elevator From the utility model DE-GM 88 07 219 is one Elevator became known with a from the bottom of the lower floor to the ceiling of the upper floor reaching frame as a guide element of an elevator car.
  • the frame points below the ceiling of the upper floor a cross-beam stage for the electric motor, Elevator winch and switchgear.
  • the elevator car slides on rollers on the inside of angle iron of the frame.
  • the elevator ropes are over two Deflection pulleys that are at the level of the stage fed to a rope drum and opened or closed in opposite directions settled.
  • a disadvantage of the known device is that the arrangement of the drive unit and the cable guide not suitable for an elevator system with a counterweight. Another disadvantage is that the below the ceiling arranged drive unit with motor and elevator winch and switchgear for maintenance work with difficulty are reachable.
  • the invention seeks to remedy this.
  • the invention as characterized in claim 1 solves the problem to avoid the disadvantages of the known device and to create an elevator system with a drive unit, which can be arranged in a space-saving manner in the elevator shaft and is easily accessible.
  • Fig. 1 denotes a self-supporting shaft, in which an elevator car 2 and a counterweight 3 are movable. Elevator car 2 and counterweight 3 will be driven by a drive unit 4 by means of ropes 5 and of guide elements 6, 7, 8 in the elevator shaft 1 guided, one leg of a guide element the guidance of the elevator car 2 and the other leg a guide element for guiding the counterweight 3 serves.
  • a carrier yoke 9 At the upper ends of a first guide element 6 and a second guide element 7 is a carrier yoke 9 arranged.
  • the carrier yoke 9 can also on the shaft head be arranged.
  • the ropes 5 end on the one hand first fixed point 10 of the carrier yoke 9 and on the other a second fixed point 11 of a third guide element 8.
  • the example of synthetic fibers or steel fibers existing ropes 5 run from the first fixed point 10 a first roller 12 arranged on the counterweight 3, then via a second roller 13 arranged on the carrier yoke 9, then via a traction sheave 4.1 of the drive unit 4, then via a third roller 14 arranged on the carrier yoke 9, then over one arranged on the underside of the elevator car 2 fourth roll 15 and fifth roll 16 and from this to second fixed point 11.
  • FIGS. 2 and 3 show a with a swivel arm 17 in Connected frame 18 on which the drive unit 4 is arranged.
  • the swivel arm 17 is on a means Gear 19 and drivable pivot axis 20 is arranged in the operating state by means of a securing element 21, for example a screw connection with the carrier yoke 9 connected and secured, the drive unit 4th below a shaft head cover, not shown in horizontal position with the traction sheave 4.1 down.
  • the gear 19 is used to pivot the drive unit 4 for example by means of a crank pin 22 attachable crank driven.
  • the gearbox can too be driven by a motor.
  • the 19 driven pivot axis 20 pivots the pivot arm 17 and thus the frame 18 with the drive unit 4 in the Elevator shaft 1. In the one shown with a broken line Location are assembly, maintenance and repair work easily and easily accessible.
  • a rope deflection 23 is loosely connected to the pivot axis 20 and prevents that there is no excessive cable pull on the
  • Fig. 4 shows the guidance of the ropes 5 from the second reel 13 on the traction sheave 4.1 and from this to the third Roll 14.
  • the rope level changes from horizontal to rotated vertically and back to horizontal. With enough Distance between rollers 13, 14 and traction sheave 4.1 can the cable pull can be neglected.
  • FIG. 5 shows those arranged on the carrier yoke 9 Bearing bracket 24 and bearing 25 held pivot axis 20. Das one end of the pivot axis 20 is fixed to the pivot arm 17 connected. At the other end of the pivot axis 20 is a worm wheel 27 driven by a worm 26 arranged. The screw 26 is connected to the Crank pin 22. During the swiveling process, the loose remains on the Pivot axis 20 mounted rope deflection 23 in place and prevents excessive cable pull on the traction sheave 4.1.
  • FIG. 6 shows the drive unit consisting of an annular motor 30, for example a Synchronous motor with a high number of poles, a braking unit 31, a rotary encoder 32 and the frame 18, as shown in FIG. 7 the frame 18 can be seen in the shape of a bowl has a central hollow axis 33 and at the foot with the Swivel arm 17 is connected.
  • an annular stator 34 of the motor 30 On the inside wall of the frame 18 is an annular stator 34 of the motor 30 arranged.
  • Rotor 35 and traction sheave 4.1 form one rotating unit, which is rotatable by means of bearings 36 on the Hollow axis 33 is supported.
  • the bearings 36 take the forces the traction sheave 4.1 and lead rotor 35 and Traction sheave 4.1.
  • the encoder 32 is on the drive pulley side arranged in the hollow axis 33 and is by means of a the hollow axis 33 extending shaft 37 driven, wherein the shaft 37 by means of a plate 38 with the rotating Unit is connected.
  • Sheet packs with permanent magnets 35.1 of the rotor 35 are clamped with holders 39 and so molded that they have internal frictional forces of Can accommodate inner brake shoes 40 of the brake unit 31.
  • the inner brake shoes 40 are on brake shoe levers 41 arranged.
  • the brake shoe levers 41 are at one end with the frame 18 firmly connected bolts 42 rotatable stored and at the other end each with an actuator 43 of an electromagnet 44 connected.
  • the electromagnet 44 releases the inner brake shoes 40 by means of springs 45 generated spring forces.
  • Electromagnet 44 and springs 45 are constructed symmetrically and connected to the frame 18, so that the brake unit 31 even if one Half of the brake remains functional.
  • the opening of the bowl is by means of a cover 46 locked. Under the cover 46 is room 47 for Electronics and control components of the drive unit 4.
