Definitions

  • the present invention relates to an arrangement for the installation of the machine room of an elevator as defined in the preamble of claim 1 and to a procedure for installing the machine room as defined in the preamble of claim 8.
  • the machine room In the case of traction sheave elevators, the machine room is conventionally placed in a separate space above the elevator shaft.
  • the elevator ropes are passed into the shaft via traction and diverting pulleys provided in the machine room.
  • the machine room contains a drive motor, possibly a gear system connected to it, and the equipment for the supply of power and control of the motor.
  • the various pieces of equipment are mounted in specific locations in the machine room according to the requirements of the elevator construction.
  • the elevator machinery is pre-installed on a base which is then placed on top of the elevator shaft, whereupon the positions of the various parts of the machinery are adjusted more accurately.
  • the installation of the machine room equipment in the machine room comprises several operations which are laborious and time-consuming to carry out on site.
  • the base of the hoisting motor and the traction sheave have to be mounted in place and their positions adjusted using a plumb line.
  • the vibration dampers and insulations have to be mounted and adjusted.
  • an overspeed governor and a control unit are installed in the machine room.
  • the hoisting motor and the overspeed governor are connected to the control unit.
  • the cabling for the elevator car and shaft are installed and passed into the shaft.
  • a wooden locator is made for the plumb lines of the shaft.
  • the ropes are mounted and the functions of the elevator are adjusted. Due to the circumstances, it is difficult to achieve a good installation result.
  • skilled persons of several different specialties are needed for the installation of the various components.
  • US 3,519,101 shows a base for the components of an elevator drive machinery. This base can be lifted stepwise according to the construction progress of very high buildings. However, after mounting this base in a working position the components supported by said base have to be adjusted in appropriate positions.
  • US 5,033,586 discloses an elevator assembly which is designed to operate an elevator car in a building under construction. Also this assembly includes an unitary frame having a machine room module with a machine traction sheave and all necessary components. Also in this construction all the components of the elevator have to be adjusted after mounting the frame in the first working position. This adjustment is very laborious.
  • the object of the present invention is to provide an installation method for a machine room construction which can be performed quickly and accurately. This object is solved by the procedure of the invention according to claim 1. Preferred embodiments of the invention are defined in the subclaims.
  • the machine room can be quickly and accurately positioned on site.
  • the base of the machine room as well as the holes needed in it for the hoisting ropes and other components extending into the shaft can be prefabricated and made to more accurate dimensions.
  • the tests, wiring and adjustments, performed in a protected factory environment, are carried out more accurately. On-site adjustments are limited to a minimum.
  • the elevator can be taken into use soon after it has been brought to the building site.
  • the boundary between the elevator supplier and the building contractor becomes clearer. Deviations in the dimensions of the elevator shaft are not important, but the base allows relatively large variations.
  • Fig. 1 shows a machine room module 1 for implementing the method according to the invention, comprising a base 2 with a hoisting machinery 4 mounted on supporting rails 6.
  • the hoisting machinery comprises at least a motor 8, a gear system 10 and a traction sheave 12 attached to it.
  • the hoisting ropes 13 running over the traction sheave are passed further via a diverting pulley 14 mounted on the base.
  • the base 2 is provided with mounting bases 16 and 18 for the control unit and the over-speed governor and other necessary equipment to be installed in the machine room.
  • the frame of the base 2 is manufactured from steel rails 20 to which a floor 22 is attached.
  • the floor consists of an acoustic panel with a surface of a material strong enough to be stepped on, e.g.
  • the floor structure may vary greatly as long as it meets the requirements regarding noise damping and installation and maintenance work.
  • Mounted on the steel rails forming the frame are upper insulators 24 bearing the supporting rails 6 of the hoisting machinery.
  • the insulators are made of e.g. polyurethane.
  • the frame of the base 2 is mounted on top of the top module 26 forming the topmost part of the elevator shaft.
  • the top module 26 consists of a steel frame of a size essentially corresponding to the cross-section of the elevator shaft, comprising an upper and a lower frame 28 and 30 and vertical supports 32 connecting them and the required diagonal braces 33.
  • Fitted on the lower edges of the top module are lower insulators 36, which are likewise e.g. polyurethane insulators. Via these insulators, the machine room module is supported by the topmost floor beside the elevator shaft of the building.
  • the top module forms the topmost part of the elevator shaft.
  • the frame of the base, the top module with its supporting structures and the insulators form the supporting elements of the machine room module.
  • the supporting elements are provided with height adjusting elements 37 fitted on top of the insulators to permit adjustment of possible irregularities in the upper edges of the shaft walls.
  • the base is provided with points of attachment for plumb lines 38, and the plumb lines are preferably fastened beforehand to these points to permit adjustment of the position of the base.
  • Mounted on the lower edges of the top module 26 are adjustable lateral supports 34 designed to hold the machine room module laterally in place, attaching it to the walls of the elevator shaft.
  • the wall surfaces of the top module consist of acoustic panels 29.
  • Fig. 2 illustrates the installation of a machine room module 1 on top of an elevator shaft 40.
  • the base of the machine room module is provided with fixing points 42 for a hoisting cable to support the module when it is being lowered onto the shaft (Fig. 2a) and positioned.
  • the plumb lines 38 are passed down into the shaft 40 and their distances from the shaft walls 44 are measured (Fig. 2b).
  • the position of the module is checked and adjusted to bring the module to its final position by moving it by means of the hoisting apparatus (Fig. 2c).
  • the module is fastened to the walls 44 of the elevator shaft by moving the lateral supports 34. Insulators 46 are fitted between the shaft walls 44 and the lateral supports 34 to maintain the level of insulation of the machine room module.
  • the machine room module may be provided with side walls 48 and a ceiling 49 as indicated by the broken lines in Fig. 2.
  • Fig. 3 shows another construction and uses the same reference numbers as Fig. 1 to indicate corresponding parts.
  • Attached to the underside of the steel rails of the base are plates 45 forming an additional mass and below them insulators 36 which rest on the upper edges of the shaft walls 44.
  • the additional mass is designed in the first place to improve the insulation structure between the machine room module and the shaft walls 44.
  • the elevator shaft has been built to its full height, in which case the base is supported directly by the upper edges of the shaft walls.
  • the steel rails of the base frame together with the insulators constitute supporting elements by which the machine room module is supported on the top part of the walls of the elevator shaft.
  • the solid structure between the upper 24 and lower 36 insulators and the base frame together with or without a top module constitute an advantageous double insulation structure which has good noise damping characteristics.
  • the insulators in the above example are fitted between the top edges of the shaft walls and the machine room module, they can as well be placed between parts of the machine room module, in which case the machine room module rests directly on the top edge of the walls.
  • the machine room module may also be secured with fixing elements such as bolts to the walls of the elevator shaft instead of just resting gravitationally on the walls.
  • Fig. 4 presents yet another module.
  • the base 50 of the machine room module is placed above the elevator machinery.
  • the hoisting motor 8, gear 10 and the traction sheave 12 of the elevator as well as the diverting pulley 14 hang down from the base.
  • the base 50 Via vertical module walls 52, the base 50 is supported by the top edge 54 of the shaft walls 44. Insulators 56 are provided between the module walls and the base and between the module walls and the shaft walls.
  • the hoisting motor and the gear system are isolated from the rest of the machine room space by means of protective plates 59, which can be removed or opened for servicing.
  • the control unit 58 is attached to the module walls 52.
  • Mounted in the top part of the elevator shaft is a plate or support which can be turned across the shaft so as to form a servicing platform.
  • the servicing platform consists of a supporting part 62 whose one end 66 is attached to a shaft wall 4 and whose other end 68 rests on the topmost floor 64 served by the elevator.
  • Turnably attached to the support 62 is the platform 60 itself, whose other edge is supported by a wall 44 of the elevator shaft.
  • the platform 60 is in a substantially horizontal position. During normal operation of the elevator, this structure lies flat against the shaft wall or is removed altogether.
