Embodiment Construction

[0018] Reference will now be made in detail to specific embodiments of the accompanying drawings, examples of which are illustrated in the accompanying drawings.

[0019] exist figure 1 In, a block diagram of an embodiment of the invention is disclosed. In this figure, a conventional elevator is illustrated. The elevator comprises an elevator car 10 , a counterweight 11 and a traction device 12 . An elevator is installed in the elevator shaft. The traction device 12 is typically driven by an electric motor. The traction device is controlled by a controller 13 . In normal use, the controller is configured to receive instructions from the elevator control which are used by the elevator user by calling the elevator and selecting a destination. In response to these requests, the controller 13 generates control signals for controlling the general movement of the elevator. The control signal contains the information necessary to accelerate and decelerate the elevator car so th...

Abstract

Various embodiments in the invention relate to an elevator structure test. Loose joints and other defects, such as manufacturing, installation, wearing and other similar defects, are hard to find. Especially in case of passenger elevator it is crucial to find these defects in order to produce safe elevators. Testing can be done using a special test signal that is formed by combining an excitement signal with movement control signal. The test signal causes purposively pulsating or oscillating movement of the elevator car that deviates from the ordinary movement of the elevator. This movement causes noises from loose joints and other defects. The sources of these noises can then be located and the defects can be fixed.

Description

technical field [0001] The present invention relates to testing the structure of elevators. Background technique [0002] Elevators are commonly used to transport people and materials. Especially in passenger elevators, the responsibility towards passengers necessitates high-quality testing. Testing and verification are commonly used to identify possible manufacturing and installation defects such as loose joints, loose wires, incorrect spacing of components, detached connectors in electrical equipment, forgotten tools, and any other defects that may Caused by improper installation, material problems, or any other human error. Extensive testing is usually carried out after the elevator is installed or manufactured, however, these defects can also be caused by installed spare parts, wear and tear, vandalism, or any reason that affects the elevator after installation. In other words, a defect is a malfunction or behavior that needs to be fixed in order to improve the qualit...
