The action of safety tongs device is: make rope-clamping pliers clamp the limiting device rope through the velocity limiter action; Downward operation along with car; Governor rope is mentioned the safety tongs connecting rod mechanism; Cause the action of safety tongs connecting rod mechanism,, impel the voussoir of safety tongs in its pincers seat, upwards to slide through shift mechanism pull-up lifting rod; When voussoir with produce rubbing effect after guide rail contacts; Drive the safety tongs braking element and contact, make the Anzhen Flyover safety tongs be clamped on the guide rail stop car simultaneously with guide rail.
The Generally Recognized as safe clamp device is installed on car bottom girder or two heel posts, mainly is made up of pincers seat, voussoir, lifting rod, stretching structure and connecting rod mechanism etc.The general complex structure of existing safety tongs connecting rod mechanism is assembled not convenient; For the mechanical action inaccurate coordination of elevator appearance hypervelocity, disconnected rope phenomenon, reduced the function of safety protection of safety tongs device simultaneously.
Summary of the invention
The present invention is directed to the deficiency of prior art; A kind of elevator safety gear connecting rod mechanism is provided, and it is simple in structure, and assembling is convenient; Mechanical action in the time of can carrying out simultaneously elevator appearance hypervelocity, disconnected rope phenomenon is well coordinated, and has guaranteed the function of safety protection of safety tongs device effectively.
For realizing above technical purpose, the present invention will take following technical scheme:
A kind of elevator safety gear connecting rod mechanism is connected between safety tongs and the governor rope; Comprise adapter shaft and the spindle nose assembly that is installed in the adapter shaft two ends respectively through the Flexible Connector of pretension setting; Said spindle nose assembly comprises that dialling support body, first connects the bearing pin and the second connection bearing pin; Said first end that connects bearing pin is fixed with dialling support body, and the other end then is connected with governor rope; The said group of support body connects bearing pin through second and is connected with the movable voussoir of safety tongs, and dial offered on the support body to be used for the mounting hole that the second connection bearing pin wears be waist-shaped hole; Flexible Connector is socketed in the periphery that connects axis body, dials support body is socketed in adapter shaft through axle sleeve axle head; In addition, the axis body of said adapter shaft is connected with the switch press plate of safety switch assembly, and the reseting elasticity of said Flexible Connector is 15-18Kg.
The adjusting pad of the spindle nose component synchronization motion that is used to guarantee the adapter shaft two ends is installed on the said group of support body, and this adjusting pad is through placing the adjustable bolt positioning and locking of dialling in the corresponding bar hole of being offered on the support body; Simultaneously said second axle head that connects bearing pin passes on the adjusting pad and fixes with the movable voussoir of safety tongs behind the corresponding through hole of offering.
According to above technical scheme, can realize following beneficial effect:
The present invention adopts simple physical construction, has realized being connected between the movable voussoir of governor rope and safety tongs; Adopt Flexible Connector to realize of the present invention resetting; Be used for second and connect the waist-shaped hole that bearing pin wears dialling to offer on the support body, so that dial the adjusting of installation site between support body and the movable voussoir; Adopt adjusting pad, to carry out each group support body respectively and installation site adjustment between the movable voussoir of its cooresponding safety tongs, to guarantee the conformability of spindle nose assembly action.Hence one can see that: the mechanical action when the present invention can carry out elevator appearance hypervelocity, disconnected rope phenomenon is well coordinated, and has guaranteed the function of safety protection of safety tongs device effectively.
