Definitions

  • the invention relates to an emergency drive for an elevator with one moving an elevator car and a counterweight Drive unit consisting of motor and traction sheave, over the one connected to the elevator car and the counterweight Ropes are guided, with the emergency drive on during emergency operation the drive unit acts.
  • the machine frame On the bearing block and the The machine frame is also a shield-bearing machine Counter roller carrier arranged with a counter roller, this serves by the dimensions of the elevator car and the Counterweight and the cable guide specified Keep the rope strand distance.
  • a manual drive on the main shaft with one Worm gear enables in case of power failure manually moving the main shaft.
  • a disadvantage of the known device is that a great effort to move the main shaft necessary is.
  • such emergency drives are very expensive.
  • 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 propose a simply built emergency drive.
  • Fig. 1 shows the fully assembled drive unit, in essentially consisting of an engine 1, a Bearing plate serving motor stand 2, one as a bearing plate serving bearing block 5, a traction sheave 15 and one Machine frame 7 with counter roller carrier 9.
  • About the Traction sheave 15 are ropes, not shown, which are connected at one end to an elevator car and the are connected to a counterweight at the other end.
  • the stator of the electric motor 1 is connected by means of a flange screwed to the motor stand 2.
  • the rotor of the electric motor 1 sits on a free end of a traction sheave 15 load-bearing shaft on the bearing block 5 and on the motor stand 2 is stored.
  • a brake 6 is in the inner area of the Motor stand 2 arranged and with the casing 3rd covered.
  • the Brake 6 also in the inner area of the bearing block 5 be arranged.
  • the motor stand 2 and the bearing block 5 are on Machine frame 7 arranged, which at each corner has an adjustable support element 8.
  • the Counter roller carrier 9 is on the underside of the Machine frame 7 arranged. All electrical connections the drive unit are located in a terminal box 10.
  • the traction sheave 15 is after opening one Sliding cover 47 accessible from the outside.
  • Fig. 2a to 4b The construction of the emergency drive is in Fig. 2a to 4b explained in more detail, wherein in Fig. 2a and 2b assembled and an exploded in Fig. 4a and 4b Representation of the assembly can be seen.
  • Fig. 3 shows Details of one arranged on the traction sheave 15 Sprocket 39 and Fig. 5a and 5b an auxiliary device for the emergency drive.
  • the traction sheave 15 is over the ring gear 39 driven.
  • the ring gear 39 is toothed Segments 39.1 constructed, which by means of dowel pins 40, which are driven through the holes 39.2 and in the corresponding holes 15.1 in the traction sheave 15 sit.
  • the screws 41 through the ring gear 39 inserted and screwed into the traction sheave 15 are, keep the segments 39.1 in the axial direction together.
  • a segment 39.1 is made of layered, toothed sheet metal segments constructed by means of punching or Cutting processes are cheap to produce.
  • the Sprocket 39 is made of several, mutually in the Circumferentially offset layers of toothed Segments 39.1, each segment 39.1 at least two holes 39.2 for those in holes 15.1 Have traction sheave 15 pressed-in dowel pins 40.
  • the ring gear 39 is by means of a on the shaft Hydraulic motor 43 mounted pinion 42 driven.
  • the Motor 43 is for this purpose in a receiving bore 5.1 the bearing block 5 inserted and fastened with screws.
  • the mounting hole 5.1 is in the area with a cover 45 is covered.
  • Hydraulic motor 43 can be, for example, a mains-powered one or battery-powered electric motor can be provided.
  • a motor driven toothed belt can be provided, the Motor power to a provided instead of the ring gear 39 Transmits toothed belt wheel, the toothed belt wheel as the Sprocket 39 is arranged on the circumference of the drive pulley 15.
  • the end cover 45 has an opening 45.1, which with one in the guides 45.2, 48 and 49 Sliding cover 47 is closable. Before the launch of the Hydraulic motor 43, the sliding cover 47 must be in the open Position. In doing so, a Safety switch 50, whose plunger 50.1 through the hole 45.3 protrudes in the end cover 45 through which Actuation curve 47.1 pushed back, with a Safety circuit is interrupted, so that the operation of the Electric motor 1 is not possible during emergency operation.
  • 5a and 5b show a mobile hydraulic unit, which consists of a carriage 51 with a carrier 51.1 for the Hydraulic motor 43, a carrier 51.2 for receiving a Hydraulic unit 52, wheels 51.3, a bracket 51.4 for Placement of the hydraulic hoses and two more Ironing 51.5 for rolling up the electrical cable for the Feeding a pump motor 53 exists.
  • the hydraulic unit 52 consists of a pump Pump motor 53, which has a motor switch 54 can be turned on and a directional valve 55 for the Control of the hydraulic motor 43.
  • Other elements of the Hydraulic units 52 are adjustable Pressure relief valve 56 and an oil filter 57. In machine rooms without an emergency power supply, instead of the pump motor 53 a hand pump with hydraulic accumulator can be provided.
