Description
Technical field
The utility model relates to a kind of elevator safety technical field, especially relates to a kind of elevator wire rope degree of tightness perceptron.
Background technology
For elevator, be closed in hoistway, its steel rope is not all to be in people's the visual range; When if unsafe condition such as unexpected loosening or fracture appears in steel rope; Be directly connected to the in-use performance of elevator and passenger's the security of the lives and property, can make a response rapidly to abnomal conditions such as steel rope become flexible, under this type situation, move with effective prevention elevator so need design a kind of structure; Therefore; The steel rope that has the contriver to propose " the locking rope device of a kind of elevator " (application publication number CN 101941625A) by name loosens device, and it comprises rope hitch plate, runner assembly, switch fixed mount and runner assembly bracing frame, two connecting panels that said runner assembly comprises rotating shaft and is connected the rotating shaft two ends; Said runner assembly bracing frame comprises fixed support plate and resilient mounting thick stick; Said resilient mounting thick stick is between fixed support plate and switch spit of fland plate, and said runner assembly is hinged with the fixed support plate that is fixedly mounted on the rope hitch plate, and this runner assembly is supported on the resilient mounting thick stick; Said switch fixed mount is fixedly connected on the rope hitch plate hangingly, and on the switch fixed mount safety switch is installed.This public technology can rupture to elevator wire rope, loosening accident is made reaction rapidly; Automatically cut off the electricity supply, the accident of the rushing to summit generation that the wire cable rupture phenomenon causes appears in the braking elevator when avoiding cage operation effectively; Guarantee the operating safety of elevator; But have complex structure, the higher deficiency of cost, in addition, complex structure can cause the reliability defect of insufficient.
Summary of the invention
The utility model main purpose provides a kind of simple in structure, elevator wire rope degree of tightness perceptron that reliability is higher.
The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals: a kind of elevator wire rope degree of tightness perceptron; It is characterized in that: the slack rope seat of cavity, the pull bar that can on the slack rope seat, slide are arranged in comprising, and send the touch switch that signal is given external control system by the pull bar triggering; Said pull bar comprises bar portion, and bar portion is in that the outer end of slack rope seat is fixed with U type frame, the end that is in the slack rope seat is fixed with catch, is arranged with an end in the bar portion and is resisted against the spring on the catch sidewall; Be provided with guide wheel in the said U type frame, this guide wheel circumference is provided with the annular groove adaptive with elevator wire rope.During use; The slack rope seat is fixed; And making pull bar vertical substantially with steel rope, steel rope passes and is resisted against the annular groove of guide wheel, when steel rope is stretching between U type frame and guide wheel; The tension force of steel rope is outwards pulled out pull bar from the slack rope seat through guide wheel, makes catch break away from the trigger part of touch switch; When steel rope became flexible or rupture, pull bar moved in the slack rope seat under action of the spring, and catch triggers touch switch, and touch switch sends signal and gives external control system.This structure, simple in structure, be easy to make, cost is lower; Simultaneously, this simple structure has only the motion of railing linear slide, makes that integrally-built reliability is higher, has improved the reliability that detects the steel rope degree of tightness.
In order to prevent that pull bar from rocking, as preferably, be fixed with sliding sleeve on the said slack rope seat, said pull bar is set in this sliding sleeve slidably.Through the sliding sleeve guiding, make pull bar keep straight-line motion preferably.
As preferably, be provided with the counterbore of ccontaining screw head in the middle part of the said catch, this counterbore (51) is taper or cylindricality.In bar portion, the screw head counterbore that submerges makes the screw surface can not protrude from the surface of catch to catch through screw retention, avoids screw head to contact with touch switch and influences the reliability of detection.
As preferably, said touch switch is provided with 1 or 2.When touch switch is set to 2, one of them can be used as pilot switch, and when one of them damaged, another guaranteed that still system normally moves, and has improved safety effectively, and is beneficial to and safeguards and maintenance.
For being easy for installation and removal, as preferably, said slack rope seat is provided with the mount pad of captiveing joint with elevator.
Because steel wire penetrating U type frame also is resisted against in the groove of guide wheel; So no matter be in operation or in the installation process, need make annular groove consistently with trend steel rope, be beneficial to install or twine; Therefore as preferred, the inner chamber cross-sectional plane of said slack rope seat is square; Said catch periphery has a sidewall at least on the sidewall of this square cavities.Catch one sidewall is on the sidewall of this square cavities; Make the pull bar can be along its rotational; Play position-limiting action, make the axis of guide wheel vertical with the steel rope trend all the time, even also the trend of annular groove is consistent all the time with the steel rope trend; Both be beneficial to and installed and debugging, and avoided guide wheel to rotate again steel rope is twined on it.In addition, the one or more sidewalls of catch are on this square cavities corresponding side walls, and that also can give pull bar mobilely plays auxiliary directional tagging.
Therefore, the utlity model has rational in infrastructure, be easy to make, cost is lower, and the higher beneficial effect of reliability.
