Definitions

  • the invention relates to a drive for an elevator with a rope held car according to the preamble of claim 1.
  • a drive motor is used that is flat the shaft wall abuts and in a lateral area between this and there is space for the car.
  • the invention is based on the problem of being able to be integrated into the elevator shaft To create drive for the elevator car, in which a conventional Drive motor can be used.
  • a drive motor a conventional asynchronous motor can be used, the Dimensions do not have to be adapted to a flattened installation position. If the shaft of the drive motor is in a particularly favorable mounting position parallel to the level of doors blocking the shaft in stages aligned and the drive motor in an upper area above a Door fighter profile is arranged, one located above this door profile otherwise unused area used to accommodate the drive motor become.
  • the drive motor can also be located below the bottom door frame to be ordered.
  • Driving wheel By combining belt, brake and traction sheaves into one Driving wheel can be made a particularly flat unit, for example can also be arranged behind a lateral vertical guide rail.
  • the pulley with a cranked carrier part is particularly advantageous provided, creating an annular receiving space for one on the brake disc acting braking device arises; then this does not protrude above the Outside dimensions of the driving wheel.
  • a braking device When using a braking device according to the invention on a driving wheel ensures that if the electrical power supply fails, the The brake closes automatically and the car is stopped.
  • the braking device can also be used with other drive units Find.
  • a pressure medium reservoir is particularly advantageously provided in order to thereby create a pressure medium reservoir manual ventilation of the brake and thus a movement of the car even after To allow failure of the pump providing the pressure medium.
  • FIG. 1 in an elevator 1, the has a vertical shaft 2 for moving a car 3 up and down, In the head region 4 of the shaft 2, an inventive drive with a drive wheel 5 and a drive motor 6 acting thereon.
  • the Shaft 2 is closed at the top and bottom and does not have a separate one Machine room on.
  • the driving wheel 5 comprises a traction sheave 7, which is overrun by ropes 8, on which the car 3 is attached.
  • the drive wheel 5 has a pulley 9 and a brake disc 10, which with the pulley 9 and Traction sheave 7 is combined to form a flat drive wheel 5.
  • the drive wheel 5 is on a support frame 11 about a fixed axis of rotation 12 stored.
  • a rocker 13 is articulated, which the drive motor 6 carries, the rocker 13 via a tension spring 14 with a Force is applied in the sense of tensioning a drive belt 15 the rocker 13 acts.
  • the tension spring 14 is not only the one shown mechanical spring, but also other known clamping elements, for example also hydraulically acting.
  • the axis of rotation 12 of the driving wheel 5 is vertical in the guide plane 16 Guide rails 17 arranged that the vertical longitudinal median plane of the car 3 are assigned.
  • the support frame 11 can in the space between the Guide rail 17 and a side shaft wall 18 arranged to save space his.
  • the shaft 19 of the drive motor 6 is parallel to the Level 20 of floors 21 which block access to shaft 2 arranged.
  • the drive motor 6 is in the area above a door fighter profile 22 held, which here in the shadow area of the door fighter profile 22 resulting pocket-like, otherwise unused area of the shaft 2 is being used.
  • the drive therefore enables a very space-saving arrangement.
  • the drive motor 6 is located on the side of the movement corridor of the car 3.
  • the drive wheel 5 is constructed so that the brake disc 10 in one piece with a Hub part 23 is formed and the drive pulley 7 and the pulley 9th are fixed on the hub part 23 via a bolt connection 24.
  • the hub part 23 is on a pivot pin 25 comprising the axis of rotation 12, which on the Support frame 11 is supported, stored.
  • the traction sheave 7 has the smallest diameter and is from the brake disc 10 protrudes radially.
  • the pulley 9 projects beyond the brake disk 10 and has a cranked portion 26 of its support member, thereby one Recording space 27 forms for receiving at least one braking device 28.
  • the brake device 28, with its brake shoes 29 on the brake disc 10 acts, therefore does not protrude the driving wheel 5.
  • the drive belt 15 provides a speed reduction between the motor shaft 19 and the pulley 9 safely, for the car 3 over the Ropes 8, which is arranged at the upper edge region of the counterweight 30 Roll over 31, a 2: 1 suspension can be formed.
  • the frame 11 provided for holding the drive wheel 5 has a drive wheel 5 enclosing main part 32, which has a front and a rear Sheet 33.34 and this connecting cross bracket 35, the total of in Well arranged base 36 are screwed, includes. From the main part 32 extends outwardly a cantilever part 37 on which the rocker 13 for the drive motor 6 is articulated on a pivot axis 38. This one too Cantilever part 37 is present both in front of and behind the drive wheel 5, so that a one-sided loading of the linkage 38 is avoided.
  • the torque transmitting connection between the drive motor 6 and the drive wheel 5 is produced via at least one drive belt 15.
  • This is special advantageously designed as a flat V-ribbed belt, which has a high Has tensile strength along its direction and also low wear is.
  • a V-belt or other power transmission belts also come in principle in question, as well as a chain drive, although the V-ribbed belt is preferred.
  • a support frame 111 of the drive according to the invention arranged in the shaft base 40, wherein in turn, the support frame 111 carries the drive wheel 5 and the drive motor 6.
  • the cables 8 are not held by the rotating drive wheel 5
  • a carrier 41 is additionally arranged in the shaft head 4, which corresponds with corresponding Deflection rollers 42 for holding and deflecting the cables 8 is provided.
  • a fixed holder 43 for a being is also arranged in the shaft head 4.
  • a cantilever 137 is also on the support frame 111 provided, which in turn holds a rocker 13. Even the application is realized in a corresponding manner by a spring 14.
  • the drive wheel 5 and the drive motor 6 can be identical in one pocket-like lower edge region 42 of the shaft 2 below a lower one Frame profile 43 of a door 21 are placed. Again the drive motor is involved 6 held outside the lifting corridor of the car 3.
  • a deviation in the embodiment shown in FIG. 8 compared to that shown above Version arises in that the axis of rotation 12 of the driving wheel 5 is not in the management level 16, but is laterally offset against this. This is however not mandatory, but the arrangement in the lower area can be the same be carried out as in the above embodiment.
  • the Braking device 28 comprises two arms 50, which hold the brake shoes 29, on Axes of rotation 51 are held pivotably.
  • On the brake shoes 29 opposite The side of the brake arms 50 is at least one - usually several - Compression spring 52 is arranged, the arms about the pivot axes 51 in Closure actuated so that the brakes by the mechanical compression spring 52 28 engage.
  • At least one hydraulic cylinder 53 provided, the one in the direction of opening when pressurized with pressure medium the brake shoe 29 force acting on the arms 50. Thereby the brake shoes 29 can be released and held in the open position.
  • Such braking devices 28 can basically be used with each driving wheel 5.
  • the particularly compact design shown here makes the use Such a braking device 28 particularly useful.
