Embodiment Construction

[0049] figure 1 A top view of a preferred embodiment of the measurement transducer 10 is shown, i.e. a top view of the circumferential surface F of the measurement transducer 10, in particular of the connection region 3 as will be described below, in a direction orthogonal to the measurement in the direction of the rotational axis Z of the transducer.

[0050] The measuring transducer 10 according to the invention comprises a support ring 1 and a tape measure 2 on which the tape measure 2 is circumferentially arranged (eg glued). As shown, the measuring transducer 10 can be mounted on the shaft 40 of the escalator by means of adjustment means 9 in the form of a rectangular rubber band (eg double-sided tape). The rubber band is wider than the support ring 1 and the tape measure 2. The width of the support ring 1 may be slightly larger than the width of the tape measure 2, preferably 1% to 15% larger, more preferably 5% to 10% larger.

[0051] For ease of installation, the me...

Abstract

The invention relates to a measuring transducer (10) for a shaft (40) of an escalator for providing a position code, comprising a support ring (1) and a magnetic tape measure arranged circumferentially on said support ring (2), said support ring (1) and tape measure (2) are realized in two parts in the form of preferably semicircular elements (1a, 1b, 2a, 2b), and said support ring (1) is used The connecting means (4) are selectively connectable to each other in the respective connecting areas (3), the tape measure (2) has a plurality of magnetic poles (5i) arranged in the circumferential direction, the magnetic poles (5i) being arranged in such a way are arranged in the tape measure (2) in such a way that the respective individual poles (5a, 5b) span the support ring (1) and the said measuring transducer (10) in the circumferential direction (U) of the The corresponding connection area (3) of the tape measure (2) extends.

Description

technical field [0001] The present invention relates to a measuring transducer for the shaft of an escalator for verifying a position code by means of a magnetic tape measure, and a system comprising the measuring transducer. Background technique [0002] Typically, an escalator or escalator includes a drive that drives a spindle through a chain, which in turn drives the escalator steps. If the chain breaks, the escalator steps keep moving downwards - which can lead to serious accidents if there is a high load caused by someone on the escalator. Therefore, the chain of the escalator is constantly monitored, and in the event of a chain break, the spindle is braked immediately. [0003] Conventional systems monitor the individual sprocket teeth of the chain via inductive sensors. Because the escalator's drive chain moves very slowly, the response time from this system is significantly delayed - a delayed response can cause the escalator to accelerate to a detrimental speed b...
