Abstract
The invention discloses a handrail strap speed measuring device of an escalator or a moving pavement. The handrail strap speed measuring device includes a fixed bottom plate and a nonmetal tachometer wheel of which a wheel circumference surface can be pressed by a handrail strap and which can rotate synchronously under the drive of a friction force of the handrail strap. A metal measuring point is arranged on the surface of the nonmetal tachometer wheel. A probe capable of detecting the metal measuring point so as to output a signal which reflects a running speed of the handrail strap is arranged on the fixed bottom plate. The handrail strap speed measuring device also includes a support plate rotatablely arranged on the fixed bottom plate. A hub of the tachometer wheel is mounted on one end portion of the support plate. An elastic member arranged between the other end portion of the support plate and the fixed bottom plate provides elastic restoring force for the support plate so as to make the tachometer wheel on the support plate to support outwards. An axial lead of a rotation axis of the support plate extends along the axial lead direction of the hub of the tachometer wheel. An object of the invention is to provide the handrail strap speed measuring device of the escalator or the moving pavement which can automatically adjust height according to the running condition of the handrail strap.
Description
Technical field
the present invention relates to the hand strap velocity measurement device of escalator or moving sidewalk.
Background technology
when escalator or moving sidewalk run, when the deviation value that the running velocity of handrail departs from step or pedal actual speed exceeds the scope of prescribed by standard, hand strap velocity measurement device can make escalator or moving sidewalk out of service.Hand strap velocity measurement device is typically employed on non-metal roller (or being called non-metal fifth wheel) and arranges metal measuring point, electric probe be arranged on from metal measuring point very close to position on, non-metal roller is subject to the friction force synchronous rolling of handrail, and electrically probe just can detect the speed of handrail.This device is simple and practical, but because handrail is part that is flexible, flexible, it has slack list at different service directions, the situation of pilled-in selvedge exists, when non-metal roller runs in the slack list of handrail, handrail likely raises up and causes the non-metal roller that do not rub, non-metal roller does not run, electric probe just judges handrail velocity anomaly, make escalator or moving sidewalk out of service mistakenly, this type of situation, once occur, can affect the normal use of escalator or moving sidewalk.In order to head it off, if just solely raise non-metal roller, then, when the pilled-in selvedge of handrail is run, non-metal roller is elevated rear single stressed, and the pressure born is comparatively large easily to be damaged.Non-metal roller (or being called non-metal fifth wheel) can not adjust height, does not thoroughly solve the problem.
Summary of the invention
the object of this invention is to provide non-metal fifth wheel on escalator or moving sidewalk can according to the hand strap velocity measurement device of the running condition automatic height adjustment of handrail, this ensure that fifth wheel all the time can by handrail friction running, avoid that fifth wheel is stressed to be excessively damaged simultaneously.
