Definitions

  • the present invention relates to an arrangement for the hoisting machinery of an elevator as defined in the preamble of claim 1.
  • the hoisting machinery of an elevator is located in a pit at the bottom of the elevator shaft. This can be a problem for example in case of a flood when water may enter the pit, in which case parts of the machinery can be damaged. Especially electrical parts may easily be damaged if they get wet. In addition, in the course of time dust and other dirt and debris collect in the pit, which also can damage or wear the machinery. Such dirt or debris may also increase the noise of the machinery.
  • One object of the present invention is to eliminate draw ⁇ backs of prior art technology and to achieve an arrangement for the hoisting machinery of an elevator, which arrangement contains a protective casing for the machinery, which casing protects the machinery from water and other fluids, dust, dirt and other debris.
  • Another object the invention is to achieve a standardized machinery unit, which is easy to in ⁇ stall and can be used in various kinds of elevators without making modifications.
  • the arrangement according to the in- vention is characterized by what is disclosed in the charac ⁇ terization part of claim 1.
  • Other embodiments of the invention are characterized by what is disclosed in the other claims .
  • the invention makes it possible to achieve a standardized machinery unit, which is easy to install in many kinds of elevators without making modifications at the installation site, and can be used in various elevators where the hoist ⁇ ing machinery is located at the bottom of the elevator shaft regardless of differences in technical specifications of the elevators.
  • the arrangement according to the invention also protects the hoisting machinery from water and other things, such as dust although the machinery is installed at the bot ⁇ tom of the elevator shaft.
  • the water and dust protection of the hoisting ma ⁇ chinery is done using a waterproof casing.
  • the hoisting machinery is fitted inside the casing already at the factory to form a machinery unit and transported to the installation site and installed at the bottom of the eleva ⁇ tor shaft.
  • the invention is expressed as an ar ⁇ rangement for the hoisting machinery of an elevator, which elevator comprises at least an elevator car arranged to run in the elevator shaft along guide rails, a counterweight connected to the elevator car with a traction member from below and suspension ropes from above, and a hoisting machinery equipped with a drive wheel in the lower part of the elevator shaft.
  • the hoisting machinery is fitted inside a casing and the hoisting machinery and the casing together form a machinery unit.
  • inventive content of the application can also be defined differently than in the claims presented below.
  • the in- ventive content may also consist of several separate inven ⁇ tions, especially if the invention is considered in the light of expressions or implicit sub-tasks or from the point of view of advantages or categories of advantages achieved. In this case, some of the attributes contained in the claims below may be superfluous from the point of view of separate inventive concepts.
  • the different details presented in connection with each embodiment can also be applied in other embodiments.
  • at least some of the subordinate claims can, in at least some situations, be deemed to be inventive in their own right.
  • One advantage of the arrangement according to the invention is that it protects the hoisting machinery from water, for example in case of a flood. Another advantage is that the hoisting machinery is also protected from dust, dirt and other debris, and also other fluids than water. Above- mentioned advantages lead to yet another advantage that the machinery can be normally located at the bottom of the ele ⁇ vator shaft so that it does not take unnecessary space else- where in the elevator shaft. Yet another advantage is that the casing belonging to the arrangement can be used also as a transport means to bring the machinery to the location of the elevator. A further advantage is that the casing or part of it can be made of such a material, which functions as a cooling surface.
  • the ar ⁇ rangement contains a fan, which enhances cooling of the ma ⁇ chinery.
  • the casing or ma ⁇ chine container can be pressurized using the fan.
  • the hoisting machinery unit can al ⁇ ways be similar in many kinds of elevators without any modi ⁇ fications to be made or requiring only minor modifications.
  • the arrangement reduces the noise level of the machinery.
  • al- so that the solution is inexpensive and simple to implement.
  • Fig. 1 presents in a simplified and diagrammatic side view an elevator, in which the arrangement according to the invention can be used,
  • Fig. 2 presents the hoisting machinery of an elevator lo- cated at the bottom of the elevator shaft, which hoisting machinery applies the arrangement according to the invention
