The utility model content
The utility model is to the deficiency of prior art; A kind of Elevator weight sensor safety tongs 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 utility model will be taked following technical scheme:
A kind of Elevator weight sensor safety tongs 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; One end of the said first connection 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; The axle head of the simultaneously said second connection 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 utility model adopts simple physical construction, has realized being connected between the movable voussoir of governor rope and safety tongs; Adopt Flexible Connector to realize resetting of the utility model; 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 utility model 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.
