Technical Field

The invention relates to a method for modernizing an elevator system comprising a plurality of elevators. Each of said elevators is preferably an elevator for transporting passengers and/or goods.

Background

After a long period of use, elevators have become obsolete and need to be modernized, for example to improve safety, efficiency or ride comfort. Modernization of elevators is usually achieved by replacing all components of an existing elevator. However, it is common that the hoistway and the machine room remain in their original locations.

Typically in high-rise buildings, there are two or more parallel elevators operating in groups and serving one or more common floors. There may be many such groups in the same building. In the prior art, when groups of elevators need to be modernized, they are each modernized one by one. A common method of modernizing elevators is to stop using the elevator, then remove parts of the old elevator, and then install parts of the new elevator. For example, a new car is installed into the hoistway, a new hoist is installed into the machine room, and new ropes are laid to suspend the car. After that, the elevator is put into use. Typically, buildings need to remain in normal use during modernization. The disadvantage is that the service capacity of the elevator group is greatly reduced when the elevators of the elevator group are modernized. Furthermore, workers who perform modernization may need to use the same elevators as people who normally live or work in a building.

Detailed Description

Fig. 1 shows an elevator system to be modernized. The elevator system includes: a first elevator 1 including a first car 2 in a first hoistway 3; a second elevator 4 including a second car 5 in a second hoistway 6, which hoistways are located in the same building 7. The building 7 includes a plurality of floors F. The travel zones Z1, Z2 of the cars 2 and 5 at least partially overlap (when viewed from the side). Thus, they may serve one or more of the same floors. In the embodiment shown, the travel zones Z1, Z2 of the cars 2 and 5 are similar.

A method for modernizing an elevator system includes using (also referred to as first use) a first car 2 and a second car 5 to transport passengers and/or cargo between vertically displaced floors of a building 7, as indicated by the arrows in fig. 1. The elevators 1 and 4 preferably belong to the same elevator group. The first use includes receiving a call from the user interface 90 and selecting, by the controller 50 (also referred to as a group controller) of the control system S, an elevator car 2,5 to be sent out to serve the call from a group of elevator cars 2,5, the controller 50 of the control system S being configured to control movement of both the first car 2 and the second car 5, the group including both the first car 2 and the second car 5.

The method comprises, after said first use, stopping using the first elevator car 2 to transport passengers and/or goods between vertically displaced floors, and then installing a construction time elevator 8 into the lower end of the first hoistway 3, the travel area Z3 of the car 9 of the construction time elevator 8 only partially covering the height of the first hoistway 3; and then, simultaneously using (also referred to as second use) the car 9 of the construction time elevator 8 and the second car 5 to transport passengers and/or goods between vertically displaced floors of the building 7, during which use the method comprises performing construction work in the first hoistway 3 above the travel zone Z3 of the car 9 of the construction time elevator 8, in particular above the movable support structure 10 of the elevator car 9. These steps are shown in fig. 2.

Said construction work in the first hoistway 3 above the travel zone Z5 of the car 9 of the elevator at construction time is carried out on a working platform 20, which working platform 20 is movable vertically up and down above the travel zone Z3 of the car 9, in particular movable vertically up and down above the movable support structure 10 of the elevator car 9. The working platform 20 is preferably movable by means of hoisting means 21, 22, which hoisting means 21, 22 comprise a hoist 22 mounted in the machine room MR1 of the first elevator 1 above the hoistway 3, wherein the hoist 22 is connected to the working platform 20 by means of a cable or chain 21.

The above-described preferred details of installing the construction-time elevator 8 into the lower end of the first hoistway 3 are described below.

Preferably, the aforementioned installation of the construction-time elevator 8 into the lower end of the first hoistway 3 comprises installing a movable support structure 10 of the elevator car 9 (and preferably also a counterweight 11) in the first hoistway 3 and vertically supporting on a fixed structure (not shown). Fig. 2 shows the movable support structure 10 in an installed state. The hoisting machine 16 of the construction-time elevator 8 for moving the car 9 is preferably mounted on the movable support structure 10. Preferably, the aforementioned installing the construction-time elevator 8 into the lower end of the first hoistway 3 includes: a controller 300 of the hoisting machine 16 of the construction time elevator 8 is installed. Preferably, the installation of the construction time elevator 8 described above comprises the controller 100 removing the first elevator 1. However, these steps of replacing the controller 100 with the controller 300 are not necessary, as any required changes may also be performed by reprogramming and/or rewiring.

Furthermore, installing the construction-time elevator 8 into the lower end of the first hoistway 3 comprises suspending the elevator car 9 and preferably also the counterweight 11 from the movable support structure 10 with the suspension ropes 1, as shown in fig. 2. The suspension ropes 12 extend through at least one releasable rope clamp 14 to a rope supply reservoir 13, which rope supply reservoir 13 may be in the form of one or more rope reels, and the need for additional ropes in the method may be reduced. The rope supply storage 13 may preferably be mounted on the movable support structure 10, but may alternatively be mounted elsewhere, for example in a pit or on a platform of the hoistway 3.
