Abstract
The utility model discloses a hand strap speed measuring device for an escalator or a moving sidewalk. For the hand strap speed measuring device, a support plate is rotatably arranged on a fixed bottom plate, a nonmetal tachometer wheel is arranged on one end part of the support plate, and an elastic piece is arranged between the other end part of the support plate and the fixed bottom plate, therefore, when the tachometer wheel runs at the tightened side of the hand strap, the tachometer wheel rotates vertically on the support plate under the action of pressure of the hand strap with the tightened side, so as to avoid damage of the tachometer wheel due to excessive stress, and simultaneously, the elastic acting force of the elastic piece is utilized to ensure that the hand strap with the tightened side is tightly pressed on the circumferential surface of the tachometer wheel; when the tachometer wheel runs at the loose side of the hand strap, the stress of the tachometer wheel is weakened, and under the action of the elastic restoring force of the elastic piece, the tachometer wheel rotates upwards on the support plate to enable the hand strap with the loose side to be also tightly pressed on the circumferential surface of the tachometer wheel, so that the tachometer can automatically adjust height according to the moving track of the hand strap and is ensured to run by the friction of the hand strap all the time, thereby ensuring that a probe smoothly detects a signal, and enabling the escalator or the moving sidewalk to work normally; and the tachometer wheel is not stressed excessively and is not easy to damage.
Description
Technical field
The utility model relates to the handrail speed measuring device of escalator or moving sidewalk.
Background technology
When the operation of escalator or moving sidewalk, when the deviation value that departs from step or pedal actual speed when the running velocity of handrail exceeded the scope of prescribed by standard, the handrail speed measuring device can be so that escalator or moving sidewalk be out of service.The handrail speed measuring device usually adopts and at non-metal roller (or being called the non-metal fifth wheel) the metal measuring point is set, electric probe is arranged on the position of metal measuring point close to very, the non-metal roller is subject to the friction force synchronous rolling of handrail, and electric probe just can detect the speed of handrail.This device is simple and practical, but because handrail is part flexible, flexible, it has the situation of slack list, pilled-in selvedge to exist at different service directions, the non-metal roller is when the operation of the slack list of handrail, handrail might raise up and cause not rubbing the non-metal roller, the non-metal roller does not move, electric probe is just judged the handrail velocity anomaly, make escalator or moving sidewalk out of service mistakenly, this type of situation is in case generation can affect the normal use of escalator or moving sidewalk.For head it off, if just solely raise the non-metal roller, then when the pilled-in selvedge operation of handrail, the non-metal roller is elevated rear single stressed, and the pressure that bears is large to be damaged easily.Non-metal roller (or being called the non-metal fifth wheel) can not be adjusted height, does not thoroughly address the above problem.
