Definitions

  • the invention relates to an emergency drive for an elevator with an elevator car and a counterweight moving drive unit consisting of motor and traction sheave, are connected to the elevator car and the counterweight connected ropes, wherein in emergency operation of the emergency drive acts on the drive unit and the traction sheave on the periphery drives and on the traction sheave a sprocket is provided which is in communication with a pinion of an engine of the emergency drive.
  • a reciprocating motor fed with alternating voltage consists essentially of a stator and of a rotor with a rotor hub which can be pushed onto the main shaft. At the drive end of the main shaft creates a second clamping set a firm connection between the Main shaft and rotor hub.
  • a manual drive with a worm gear acting on the main shaft enables a manual movement of the main shaft in the event of a power failure.
  • a disadvantage of the known device is that a great effort to move the main shaft is necessary.
  • such emergency drives are very expensive.
  • an elevator drive consisting of a disc motor with integrated traction sheave and outer shoe brake has become known.
  • a sprocket On the inside of a brake drum, a sprocket is provided, in which a pinion of an emergency drive acts during emergency operation.
  • the rotor of the motor is disk-shaped, wherein the traction sheave on the rotor and the brake drum are arranged on the circumference of the rotor.
  • a disadvantage of this emergency drive is the production of complex and expensive, disc-shaped rotor with traction sheave and brake drum with internal sprocket.
  • the invention aims to remedy this situation.
  • the invention as characterized in claim 1 solves the problem of avoiding the disadvantages of the known device and to propose a simply built emergency drive.
  • Fig. 1 shows the ready assembled drive unit, consisting essentially of a motor 1, serving as a bearing plate motor stand 2, serving as a bearing plate bearing block 5, a traction sheave 15 and a machine frame 7 with counter-roller carrier 9.
  • a motor 1 serving as a bearing plate motor stand 2
  • a traction sheave 15 and a machine frame 7 with counter-roller carrier 9.
  • the stator of the electric motor 1 is screwed by means of a flange to the motor stand 2.
  • the rotor of the electric motor 1 is seated on a free end of a shaft carrying the traction sheave 15, which is mounted on the bearing block 5 and the motor stator 2.
  • the free end of the shaft projects beyond the motor stand 2.
  • the traction sheave 15, which is visible through an outbreak in a cable protection shuttering 3, is mounted on the motor stand 2 and on the bearing block 5 by means of the shaft.
  • a brake 6 is arranged in the inner region of the motor stator 2 and covered with the shuttering 3. Depending on the structure of the drive unit, the brake 6 can also be arranged in the inner region of the bearing block 5.
  • the motor stand 2 and the bearing block 5 are arranged on the machine frame 7, which has an adjustable support element 8 at its corners.
  • the counter-roller carrier 9 is arranged on the underside of the machine frame 7. All electrical connections of the drive unit are located in a terminal box 10.
  • the traction sheave 15 is accessible after opening a sliding cover 47 from the outside.
  • Fig. 2a to 4b The structural design of the emergency drive is in the Fig. 2a to 4b explained in more detail, wherein in Fig. 2a and 2b an assembled and in Fig. 4a and 4b an exploded view of the assembly can be seen.
  • Fig. 3 shows details of a arranged on the traction sheave 15 sprocket 39 and Fig. 5a and 5b an auxiliary device for the emergency drive.
  • the sprocket 39 is constructed of toothed segments 39.1, which sit by means of clamping pins 40 which are hammered through the holes 39.2 and in the corresponding holes 15.1 in the traction sheave 15.
  • the screws 41 which are inserted through the ring gear 39 and screwed into the traction sheave 15, hold the segments 39.1 together in the axial direction.
  • a segment 39.1 is made up of layered, toothed sheet metal segments which can be produced inexpensively by means of stamping or cutting processes.
  • the sprocket 39 is composed of a plurality of mutually offset in the circumferential direction layers of toothed segments 39.1, each segment 39.1 have at least two holes 39.2 for the pressed in the holes 15.1 of the traction sheave 15 dowels 40.
  • the ring gear 39 is driven by means of a pinion 42 mounted on the shaft of a hydraulic motor 43.
  • the motor 43 is used for this purpose in a receiving bore 5.1 of the bearing block 5 and secured with screws.
  • the receiving bore 5.1 is located in the area covered by a cover 45.
  • a mains-powered or battery-powered electric motor can be provided.
  • a motor-driven toothed belt which transmits the motor power to a toothed ring provided instead of the toothed ring gear 39, the toothed belt wheel as the ring gear 39 is disposed on the circumference of the traction sheave 15.
  • the end cap 45 has an opening 45.1, which is closable with a guided in the guides 45.2, 48 and 49 sliding cover 47.
  • the sliding cover 47 Before the introduction of the hydraulic motor 43, the sliding cover 47 must be brought into the open position.
  • a safety switch 50 the plunger 50.1 projecting through the hole 45.3 in the end cover 45, pushed back by the actuation curve 47.1, wherein a safety circuit is interrupted, so that the operation of the electric motor 1 during emergency operation is not possible.
  • Fig. 5a and Fig. 5b show a mobile hydraulic unit, which consists of a carriage 51 with a support 51.1 for the hydraulic motor 43, a support 51.2 for receiving a hydraulic unit 52, wheels 51.3, a bracket 51.4 for placing the hydraulic hoses and two other brackets 51.5 for rolling up the electric cable for the power supply a pump motor 53 is made.
  • the hydraulic unit 52 consists of a pump with pump motor 53, which can be turned on via a motor switch 54 and a directional control valve 55 for the control of the hydraulic motor 43. Further elements of the hydraulic unit 52 are an adjustable pressure relief valve 56 and an oil filter 57. In engine rooms without emergency power supply can instead of the pump motor 53, a hand pump with hydraulic accumulator may be provided.
