Server-room-free elevator system of generator system accessible from outside

Abstract

The invention discloses a server-room-free elevator system of a generator system accessible from outside. The server-room-free elevator system (10) includes a well (20), an elevator compartment (12), and a guide apparatus set (13). The elevator compartment (12) is in kinematic connection to a generator system (14) through a pulley block (15), wherein the generator system (14) is disposed outside the well (20) and secured to a structure (30). The generator system (14) is in kinematic connection to the pulley block (15) through a transmission shaft (16).

Description

technical field [0001] The invention relates to a machine room-less lift with an externally accessible motor unit. [0002] More specifically, the present invention relates to an electrically driven elevator system that has no machine room and the motor unit is arranged outside the well. Background technique [0003] In the field of passenger and freight elevators, electrically driven elevators are known, in which the motor unit and auxiliary equipment, brakes, reduction gears and encoders are arranged in a machine room above the elevator shaft, usually arranged corresponding to the last floor reached . In modern systems, machine-room-less solutions are widely used today, in which motor groups and auxiliary equipment groups (such as brake groups, reducers, encoders, etc.) are compact and realized in such a way that they To be accommodated in the lift shaft (usually corresponding to the last floor served) or in the shaft (usually corresponding to the basement of the buildin...

AI Technical Summary

Problems solved by technology

[0005] An important limitation of these known systems is the need for specialized operators to work in the shaft in an uncomfortable and potentially dangerous environment due to the difficulties in accessing and adjusting the system as well as in maintaining and repairing the motor unit and its auxiliary equipment group arranged in the shaft. Works on its own, is suspended in a void or is obstructed with a bulky elevator car

[0006] Another disadvantage of the described machine roomless elevator system is that in the absence of power to the motor unit, unless a professional operator uses a mechanical device that activates the brakes and allows the elevator car to move by gravity or with the help of a battery or battery powered Electric motors or emergency replacement actuators, otherwise manual emergency movement of the elevator car is not possible

[0007] A further disadvantage of these types of known systems is due to the fact that in the event of a fire or flood it is not possible to make emergency manual maneuvering of the elevator car by means of the electric motor or the auxiliary accumulator or battery pack, since they are in contact with the water will not be used and is potentially dangerous
