Definitions

  • the invention relates to a hereinafter referred to as protective hood device for covering / enclosing a speed limiter of an elevator system.
  • the protective hood is designed to essentially enclose the speed limiter in the mounted state.
  • the invention also relates to a speed limiter with such a protective hood and an inspection method for inspecting a speed limiter enclosed by such a protective hood as well as to a method for starting up a corresponding speed limiter.
  • Speed limiter for elevator systems are known per se.
  • a speed limiter comprises a pulley, which is driven by means of a cable traveling along when moving the elevator car. This is provided with a centrifugal force-controlled or a mass inertia-controlled arrangement which triggers when the sheave rotates too fast. From WO2009 / 130366 such a speed limiter is known.
  • the sheave, the centrifugal or inertia mass controlled assemblies, and other required components such as axles, switches, brake components and so on are assembled in a stator or housing to the speed limiter.
  • a speed limiter must be located in a location accessible to service personnel for purposes of control and maintenance. At the same time, measures must be taken on a case-by-case basis to protect people from unintentional contact with moving parts of the overspeed governor.
  • Protective hoods for speed limiters are known for this purpose.
  • a protective cover substantially encloses the speed limiter. In essence, this means that the speed limiter is enclosed in such a way that at least one touch of moving parts of the speed limiter is prevented.
  • the speed limiter itself is, of course, in principle, independently of the protective hood functional. In principle, this means that in individual cases at most contacts available may be, which prevent normal operation of the elevator system, as long as the guard is not mounted.
  • EP 2 636 627 AI The state of the art can be referred to EP 2 636 627 AI. From this, an arrangement of a speed limiter in a coverable recess is known. This is covered if necessary by means of a protective cover.

  • Access to the overspeed governor is required, for example, to inspect and maintain the governor, or to perform tests.
  • the protective hood is designed here in order to essentially enclose the speed limiter in the mounted state. It is envisaged that the guard is modular.
  • the modular design of the protective hood consists in that it also comprises an optionally multi-part body part and a front cover which can be attached to the body part and can be detachably connected to the body part and a rear cover which can also be attached to the body part and can be detachably connected to the body part.
  • the advantage of the protective hood proposed here is that after removing one of the two covers releasably connected to the body part, one side of the speed limiter previously enclosed by the protective hood becomes accessible. After removing both covers, so both the front cover as also the back cover, the speed limiter is accessible from two sides.
  • the protective hood applies to the dimensions of the parts thereof, namely at least the fuselage part and the two covers, the following:
