Problems solved by technology

[0004] Similar to the principle of action of an eddy current brake, a short circuit in the stator section of a linear drive can lead to an excessive, undesired deceleration of the moving body and thus the car when passing this stator section due to the strong eddy currents induced in the stator winding. speed
If these decelerations are so great that, for example, the acceleration due to gravity is exceeded, there is a significant risk of accidents for transported persons and loads, especially when traveling upwards
In addition to short circuits in the windings, mechanical disturbances such as jamming and collisions between the stator and the moving body can also lead to severe decelerations with the risk of accidents
[0005] In the case of escalators and moving walks, there is also a risk of accidents if the pedals come to a sudden stop due to electrical or mechanical failure

Embodiment Construction

[0044] exist figure 1 An elevator installation is shown schematically in FIG. 2 and is generally designated 100 as a transportation installation according to the invention. The elevator installation 100 has a car 71 as a people conveyor unit, which can be moved vertically in an upward direction 91 and a downward direction 92 in an elevator shaft 90 . Likewise, although not shown in detail, the transportation device may be an escalator or a moving walk with the step 71 as the personnel conveying unit.

[0045] The elevator installation 100 is designed with a linear drive 80 . The linear drive has at least one stator 10 and at least one moving body 70 , wherein each stator 10 has at least one stator segment 20 and each moving body 70 has at least one moving body element 30 . Each stator segment 20 has a separate stator winding 22 , a possible winding short circuit in this stator winding being indicated by a switch 23 . The movable body element 30 is preferably designed as a p...

Abstract

The present invention relates to a transportation device, specifically a lift installation, escalator or moving walkway, comprising a person conveying unit (71), specifically a cabin or platform, an electromagnetic linear drive (80) for driving the person conveying unit (71), comprising at least one stator segment (20) and at least one rotor element (30), wherein the rotor element (30) can be driven by the action of force of an electromagnetic field of the stator segment (20), which is driven over, in a first drive direction (91) or in an opposite second drive direction (92), characterized inthat the rotor element (30) is movably mounted on the person conveying unit (71) in such a way that a magnetic resistance in the air gap (21) between the stator segment (20) which is driven over and the rotor element (30) can be changed depending on a drive force which acts between the stator segment (20) and the rotor element (30).

Description

technical field [0001] The invention relates to a transport device with a safety device for limiting deceleration. Background technique [0002] Transportation equipment, especially elevator equipment without rope and chain drive, escalators and moving walks sometimes use electromagnetic linear drives, which can move the elevator car independently along the vertical and horizontal travel sections, and can make the automatic The escalator treads or travelator treads move individually along the travel path without a chain connection. In this case, the electromagnetic linear drive has at least one fixed linear stator, which is installed in a plurality of parallel or continuous stator segments with individual stator windings, for example in the elevator shaft along the travel path, and has at least A linear moving body, which corresponds to the car or the platform in the context of the invention. [0003] Thus, we consider the moving body, not the car or the pedals. The movin...
