Description
TRACTION SHEAVE ELEVATOR, HOISTING UNIT AND MACHINE SPACE
The present invention relates to a traction sheave elevator, a hoisting unit and a machine space.
One of the objectives in elevator development hay been to achieve an efficient and economic space utilization. In conventional traction sheave driven elevators, the elevator machine room or other space for the drive machinery takes up a considerable part of the building space required for the elevator. The problem is not only the volume of the space required by the elevator, but also its placement in the building. There are various solutions for the placement of the machine room, but they generally involve significant restrictions as to the design of the building at least with regard to space utilization or appearance. For example, in the case of a so-called "side-drive elevator with the machine room below", a machine room or space is required below or beside the shaft, generally on the bottommost floor of the elevator system. Being a special space, the machine room generally increases the building costs.
An object of the present invention is to achieve at an economic cost a reliable elevator allowing efficient space utilization and in which, irrespective of the hoisting height, the building space required for the elevator is substantially limited to the space needed by the elevator car and counterweight on their paths, including the safety distances, and the space needed to provide a passage for the hoisting ropes, and in which the problems or drawbacks described above can be avoided.

According to a further aspect of the present invention, there is provided a traction sheave elevator system comprising an elevator shaft structure having at least one wall; a plurality of guide rails; an elevator car movable along the plurality of elevator guide rails adjacent to the at least one wall of the elevator shaft structure; a discoidal electric motor having an axis of rotation, the axis of rotation oriented in said elevator shaft structure such that the axis will interseca an adjacent elevator car; a traction sheave driven by the discoidal electric motor on said axis of rotation; the elevator shaft structure including a shaft wall having a pair of opposed inner and outer surface planes defining a solid finite thickness; and a machine space being defined in the shaft wall, the machine space being a hole extending between the pair of opposed surtace planes and being delimited in the thicknesswise direction of the shaft wall by the plane of each of the pair of opposed surfaces; whereby the discoidal electric motor is mounted on and contained within the 2a machine space such that the discoidal electric motor does not extend beyond the outer surfaces of the shaft wall.
According to another aspect of the present invention, there is provided a method for configuring the space occupied by an elevator car and the drive assembly associated therewith, the drive assembly including at least a discoidal electric motor and a traction sheave, the traction sheave being driven by the discoidal electric motor, the method comprising the steps of providing an elevator shaft structure having at least one wall;
placing the elevator car in the elevator shaft structure, the elevator car being movable along a plurality of guide rails provided in the elevator shaft structure; arranging an axis of rotation of the discoidal electric motor to be oriented in the elevator shaft structure such that the axis will intersect an adjacent elevator car; providing a shaft wall in the elevator shaft structure, the shaft wall having a pair of opposed inner and outer surfaces defining a solid finite thickness, and defining a machine spare in the shaft wall, the machine space being a hole extending between the pair of opposed surface planes and being delimited in the thicknesswise direction of the shaft wall by the plane of each of the pair of opposed surfaces; and mounting the discoidal electric motor to be contained within the machine space such that the motor does not extend beyond the outer surfaces of the shaft wall.
Various advantages can be achieved by applying the invention, including the following:
- The traction sheave elevator of the invention allows an obvious space saving to be achieved in the building because no separate machine room is required.
The elevator is cheap to install as the elevator machinery can be assembled and tested beforehand in the factory.
- Applying the invention to practice requires no major changes in the design or manufacture of the elevator.
The machinery and the instrument panel are within easy reach, so the manner of accessing the machinery for maintenance or in an emergency does not essentially differ from conventional elevators.
In the following, the invention is described in detail by the aid of one of its embodiments by referring to the attached drawings, in which 2b Figure 2 illustrates an elevator with machinery below in which an embodiment of the invention is applied;
Figure 3 illustrates the layout of the main components of an elevator employing the invention, projected on the cross-section of the elevator shaft; and Figure 4 illustrates an elevator with machinery above, implemented according to an embodiment of the invention.
Figure 1 illustrates a hoisting unit 9 for a traction sheave elevator in accordance with an embodiment of the invention. The unit in this figure is the hoisting unit of a traction sheave elevator with machinery below, in which the hoisting ropes 3 go upwards from the traction sheave 7 of the hoisting machinery 6. In the case of an elevator with machinery above, the ropes would go downwards, The hoisting machinery 6 is fixed to the support 20 of the hoisting unit, which support 20 is preferably of a framelike design.
Mounted on the frame 20 is also an instrument panel 8, which contains the elevator control equipment and the equipment needed for the control of and supply of power to the electromotor comprised in the hoisting machinery 6. The hoisting machinery 6 is of a discoidal shape and, in relation to its diameter, relatively flat in the direction of the traction sheave shaft.
The traction sheave 7 protrudes from the discoidal hoisting machinery 6 into the shaft space.
Placed on the circumference of the hoisting machinery 6 is a brake 14. An elevator machinery usable as a hoisting machinery 6 is described. Such a machinery does not require a large machine space, so it can easily be placed in an opening in the wall or in a recess made in the wall on the side facing towards the shaft. A preferable thickness of the hoisting unit 9 is about or somewhat over ten centimetres. The traction sheave 7 is not included in this thickness.
A 10 cm thick hoisting unit 9 can readily be accommodated in an ordinary elevator shaft wall because a typical wall thickness is at least about 15 cm, both in the case of a cast concrete wall and a brick wall.
Figure 2 illustrates an elevator with machinery below in which the invention is employed, the hoisting unit 9 being placed beside the shaft in its lower part.
The main parts of the elevator machinery 6 are mounted in a space limited in its maximum by the thickness of the wall of the elevator shaft 17, in an opening 15 in the wall which is open towards the shaft space and closed with a door 16 from the outside to prevent illicit access to the machinery or entry into the shaft through the opening 15. On the shaft side, the opening may be provided with a safety net or glass or the like to make sure that one cannot, for example stretch a hand into the shaft space past the equipment in the opening. In general, it is not preferable to close the machine space 15 completely from the shaft side because, regarding ventilation of the machine space 15, an advantageous solution is one in which the machine space is ventilated through the shaft. In some cases, however, closing the machine space on the shaft side may be necessary, for example to stop the propagation of noise. In such cases the machine space 15 is closed on the shaft side except for the inlets required for power transmission to the traction sheave 7 and other purposes. In any case, the machine space 15 has a depth not exceeding the thickness of the wall of the elevator shaft 17. From the hoisting machinery 6 comprised in the hoisting unit, the traction sheave 7 moving the hoisting ropes 3 (depicted in broken 214$423 lines) protrudes into the shaft 17. Figure 2 shows both the portion of the hoisting ropes passing below the car 1 over diverting pulleys 4,5 and the portions of the hoisting ropes coming down from the upper part of the shaft 17 to the traction sheave.
Figure 3 illustrates the layout of the main components of an elevator with machinery below, projected on a cross-section of the elevator shaft 17. The elevator car 1 moves along elevator guide rails 10 and the counterweight 2 along counterweight guide rails 11. The hoisting machinery 6 and the instrument panel 8 are placed in an opening in the wall of the elevator shaft 17. The traction sheave 7 protrudes from the hoisting machinery 6 and also from the opening 15 into the shaft 17. Diverting pulleys 12 placed in the top part of the shaft guide the passage of the hoisting ropes. One of the diverting pulleys 12 guides the hoisting ropes from the traction sheave 7 to the diverting pulley 13 on which the counterweight 2 is suspended and from which the hoisting ropes go further to a fixed rope anchorage at the top of the shaft. Another diverting pulley 12 guides the hoisting ropes from the traction sheave 7 to the diverting pulleys 4 and 5 attached to the car 1, by means of which the elevator car 1 is suspended on the hoisting ropes and from which the ropes go further to a fixed rope anchorage at the top of the shaft.
In the figure, the hoisting ropes are represented by their cross-sections on the traction sheave and diverting pulleys, but otherwise the ropes are not shown. At each landing, the wall of the elevator shaft 17 is provided with a door opening 18 for the landing door. The elevator car 1 is provided with a corresponding door opening 19. If the elevator car is provided with a door, its door opening 19 is closed by the car door.
Figure 4 is a diagram representing an elevator with machinery above, implemented according to an embodiment of the invention. The hoisting unit 9 is placed beside the elevator shaft 117 in its upper part. The elevator machinery 6 is mounted in an opening 115 in the wall of the elevator shaft 117. The opening is open towards the shaft and closed with a door 116 from the outside of the shaft. From the hoisting machinery 6 comprised in the hoisting unit, the traction sheave 7 moving the hoisting ropes 103 (depicted in broken lines) protrudes into the shaft 117. The figure shows the portion of the hoisting ropes 103 passing below the car 101 over diverting pulleys 104,105 and the portion of the hoisting ropes going from the traction sheave towards the counterweight.
It will be obvious to a person skilled in the art that different embodiments of the invention are not restricted to the examples described above, but that they may instead be varied within the scope of the claims presented below. For instance, the lay-out of the car and counterweight in the shaft is not a decisive question. It is also obvious to the skilled person that the drive shaft of the traction sheave can be provided with a support on the side facing the shaft as well, e.g. by using a support beam attached to the frame 5 of the hoisting machinery. The skilled person also knows that the traction sheave comprised in an elevator machinery is frequently not a fixed part of the machinery but a component which need not be mounted on its drive shaft until during installation of the elevator.
