Abstract
The invention discloses a handrail strap speed measuring device of an escalator or a moving pavement, wherein a supporting plate is rotatablely arranged on a fixed bottom plate; a non-metal speed measuring wheel is arranged on an end part of the supporting plate; an elastic member is arranged between the other end part of the supporting plate and the fixed bottom plate; thus, when the speed measuring wheel operates on a tight side of the handrail strap, the speed measuring wheel is stressed by pressure of the handrail strap on the tight side to rotate downwards on the supporting plate and is prevented from being easily damaged due to overlarge stressing, and meanwhile, the handrail strap of the tight side is tightly pressed on a circumferential surface of the speed measuring wheel by means of elastic acting force of the elastic member; when the speed measuring wheel operates on a loose side of the handrail strap, the stressing of the speed measuring wheel is weakened, the speed measuring wheel rotates upwards on the supporting plate so that the handrail strap on the loose side can also be tightly pressed on the circumferential surface of the speed measuring wheel under the action of elastic restoring force of the elastic member, the height can be automatically adjusted by the speed measuring wheel according to an operation track of the handrail strap, and frictional operation of the handrail strap is guaranteed all the time to guarantee that a probe smoothly detects a signal and the escalator or the moving pavement can normally work; and the stress of the speed measuring wheel is not overlarge and the speed measuring wheel is not easily damaged.
Description
Technical field
the present invention relates to the handrail speed measuring device of escalator or moving sidewalk.
?
Background technology
are when escalator or moving sidewalk operation; 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 make escalator or moving sidewalk out of service.The handrail speed measuring device is employed in usually on the non-metal roller (or being called the non-metal fifth wheel) the metal measuring point is set; Electric probe is arranged on the very near position of metal measuring point; The non-metal roller receives 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 a part flexible, flexible, it has the situation of slack list, pilled-in selvedge to exist at different service directions, when the non-metal roller moves in the slack list of handrail; Might the raise up non-metal roller that caused friction ring of handrail; The non-metal roller does not move, and electric probe is just judged the handrail velocity anomaly, makes escalator or moving sidewalk out of service by error; This type of situation is in case generation can influence the normal use of escalator or moving sidewalk.For head it off, if be to raise the non-metal roller singlely, then when the pilled-in selvedge operation of handrail, it is single stressed that the non-metal roller is elevated the back, and the pressure that is born is big 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.
?
Summary of the invention
the purpose of this invention is to provide non-metal fifth wheel on escalator or the moving sidewalk can be according to the handrail speed measuring device of the running condition automatic compensation height of handrail; Guaranteed that like this fifth wheel can be turned round by the handrail friction all the time, avoid stressed excessive being damaged of fifth wheel simultaneously.
are for achieving the above object; The technical scheme that the present invention adopts is: the handrail speed measuring device of a kind of escalator or moving sidewalk; Comprise fixed base plate, take turns the non-metal fifth wheel that the friction force synchronous rolling of this handrail could pushed down and can receive to side face by said handrail; The surface of said non-metal fifth wheel is provided with the metal measuring point; Said fixed base plate is provided with and can detects the probe of said metal measuring point with the signal of the said handrail running velocity of output reflection; Said handrail speed measuring device also comprises can be arranged on the support plate on the said fixed base plate rotationally; The wheel shaft of said fifth wheel is contained on the end of said support plate, is provided with the elastic component that can provide this support plate elastic-restoring force to make the outside jack-up of fifth wheel on this support plate between the other end of this support plate and the said fixed base plate, and the turning cylinder axial line of said support plate extends along the wheel shaft direction of axis line of said fifth wheel.
During
practical implementation; Be fixed with connecting panel on the said fixed base plate, be fixed with thread rod on this connecting panel, said elastic component adopts spring; This spring housing is on said thread rod; Be fixed with fagging on the said support plate, this fagging is enclosed within on the said thread rod through the perforation on it, is combined with setting nut on this thread rod; This setting nut is positioned at the outside of said fagging, and being provided with between the inboard of this fagging and the said connecting panel to provide this fagging elastic-restoring force to make support plate rotate the said spring with the jack-up fifth wheel.
During
practical implementation, an end and this support plate of the turning cylinder of said support plate fix, and the other end passes the installation perforation of said fixed base plate, is combined with nut on the position that passes, and is gapped between this nut and the said fixed base plate.
During
practical implementation, the wheel body of said fifth wheel is arranged on the wheel shaft through bearing rotationally, and this wheel shaft and said support plate fix.
are because the utilization of technique scheme; The present invention compared with prior art has advantage: support plate rotates and to be arranged on the fixed base plate, and the non-metal fifth wheel is contained on the end of support plate, between the other end of support plate and the fixed base plate flexible; Fifth wheel is when the pilled-in selvedge operation of handrail like this; Fifth wheel is rotated on support plate by the pressure of pilled-in selvedge handrail, promptly overcomes the elastic-restoring force of elastic component, and fifth wheel is inwardly withdrawn; Avoid the stressed excessive easy damage of fifth wheel, rely on the elastic acting force of elastic component to guarantee that the pilled-in selvedge handrail closely is pressed on the wheel side face of fifth wheel simultaneously; When fifth wheel moved in the slack list of handrail, fifth wheel is stressed to be weakened, then under the elastic-restoring force effect of elastic component; Fifth wheel upwards rotates on support plate, and promptly the outside jack-up of fifth wheel makes the slack list handrail also can closely be pressed on the wheel side face of fifth wheel; No matter fifth wheel runs into the slack list or the pilled-in selvedge situation of handrail like this, can both rely on elastic component automatic compensation height, and promptly fifth wheel is according to the running orbit automatic compensation height of handrail; All the time guarantee by handrail friction running, thereby guarantee that probe detects signal smoothly, make that escalator or moving sidewalk can normal operation; And fifth wheel is stressed can be not excessive, not fragile.
