Definitions

  • Fig. 2 is a sectional view of the elevator of Fig. 1,

  • the drive sheave 7 and the brake drum 8 are
  • the brake drum 8 also serves as a motor rotor.
  • a motor stator 10 is fixed to the inner peripheral surface of the case body 2 so as to face the outer peripheral surface of the brake drum 8.
  • the motor 11 that rotates the rotating unit 5 has a brake drum 8 and a motor stator 10.
  • a brake device main body 12 for braking the brake drum 8 is arranged inside the brake drum 8.
  • the brake device main body 12 is mounted on and supported by the back plate 3.
  • the support structure of the brake device main body 12 is not shown.
  • the brake device (electromagnetic brake) 13 for controlling the drive sheave 7 has a brake drum 8 and a brake device main body 12.
  • the hand-wound handle 14 for manually rotating the rotating unit 5 includes a flat handle body 15 having first and second surfaces 15a and 15b opposed to each other, and a first surface 1 5a, a plurality of (a pair of) projections 16 as handle-side engaging portions that engage with the notches 8c, and a handle 17 provided on the second surface 15b. are doing.
  • the handle body 15 has a length larger than the diameter of the case 1. It should be noted that the handle body 15 may be smaller than the case 1, but the handle 15 can be easily operated with a smaller force as the handle body 17 is larger and the handle 17 is farther from the main shaft 4.
  • the hand-wound handle 14 is mounted on the rotating part 5 simply by inserting the projection 16 into the notch 8c, so that the hand-wound handle 14 can be easily attached to and detached from the rotating part 5.
  • the hand-wound handle 14 is attached to the rotating part 5 only when necessary, and is removed from the rotating part 5 during normal operation and stored in a predetermined storage location.
  • the hand-wound handle 14 is detached from the rotating part 5, and the opening 3a of the back plate 3 is closed by the lid. Further, during maintenance and inspection of the brake device 13, the lid is removed and the opening 3a is opened. Further, when performing maintenance / replacement of the speed detector 18, the back plate 3 is removed from the case body 2.
  • the hand-wound handle 14 cannot be continuously rotated. Therefore, for example, when the hand-wound handle 14 is rotated from the position indicated by the solid line in FIG. 1 to the position indicated by the two-dot chain line, the brake device 13 is closed, and the hand-wound handle 14 is removed from the rotating unit 5. Thereafter, the brake handle 14 is attached again at the position indicated by the solid line, and the hand-wound handle 14 is rotated while the brake device 13 is opened. By repeating such operations, the drive sheave 7 is gradually rotated, and the car is moved to the nearest floor.
  • the notch 8c for engaging the hand-wound handle 14 is provided not in the main shaft 4 but in the rotating part 5, so that the main shaft 4 has a speed detector 18 Even when the speed detector 18 is mounted, the hand-wound handle 14 can be mounted from the same side as the speed detector 18. Therefore, the maintenance space can be concentrated on one side of the main shaft 4 in the axial direction, and the maintenance space to be secured can be reduced. Therefore, the elevator can be installed in a narrow space, and it is effective to apply it to a machine room-less elevator.
  • the hand-wound handle 14 can be attached without removing the speed detector 18, the manual rotation of the drive sheave 7 can be performed more easily. Further, even when the main shaft 4 does not rotate, the drive sheave 7 can be manually rotated by the hand-wound handle 14.
  • the notches 8 c are arranged symmetrically with respect to the main shaft 4, the rotating force from the hand-wound handle 14 rotates even though the hand-wound handle 14 is not supported by the main shaft 4. Part 5 can be communicated efficiently.
  • the work using the hand-wound handle 14 can be performed from the same side as the maintenance work of the brake device 13, so that the maintenance space can be reduced.
  • the rotating portion side engaging portion is formed with the notch 8c and the handle side engaging portion is formed as the projection 16, the hand-wound handle 14 can be engaged with the rotating portion 5 with a simple configuration.
  • the notch 8c is shown as the rotating portion side engaging portion.
  • a bolt hole 8e is formed on the end surface 8d of the brake drum 8 as the rotating portion side engaging portion. May be provided. In this case, the bolt holes 8e can be used for material handling during assembly in the factory.
  • the main shaft is fixed, but the present invention is also applicable to a hoisting machine in which the main shaft is rotated integrally with the rotating part.

Abstract

Selon cette invention, une unité rotative possédant une poulie motrice est pivotée autour d'un arbre principal dans une machine de levage pour ascenseur. La poulie motrice et un tambour de frein sont intégrés à l'unité rotative. Plusieurs parties d'engagement latéral d'unité rotative sont placées sur une extrémité du tambour de frein, espacées les unes des autres dans une direction circonférentielle. Une poignée manuelle permettant de faire tourner manuellement l'unité rotative possède plusieurs parties d'engagement latéral de poignée en prise avec les parties d'engagement latéral d'unité rotative.
