Abstract
The invention discloses a safety tongs lifting mechanism which comprises a pull rod and a traction rod connection seat mounted on the pull rod, wherein the rod body close to one end of the pull rod is set as a screw; the screw is in threaded connection with a lock lifting block; the other end of the pull rod is fixedly connected with a pull strip plate; and meanwhile, the traction rod connection seat, a limiting plate and two spaced wire rope grips are sequentially mounted on the pull rod between the lifting block and the pull strip plate. According to the invention, a movable wedge in the safety tongs seat can be moved so as to realize mechanical braking of a car. In addition, the safety tongs lifting mechanism has a simple structure, and is convenient to operate.
Description
Technical field
The present invention relates to a kind of shift mechanism of safety tongs.
Background technology
The elevator safety clamp device is under the manipulation of velocity limiter, after very serious fault such as hypervelocity, disconnected rope appears in elevator, with the urgent stop of car and be clamped in a kind of safety device on the guide rail.He provides the actv. protective effect to the safe operation of elevator, generally it is installed on car frame or the counterweight frame.
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.Existing safety tongs shift mechanism generally adopts syllogic, and interlude is used to install adapter sleeve, is connected with the draw bar with the limiting device rope; Then assemble for two sections of both sides through bolt.The safety tongs shift mechanism of this structure assembling trouble, and the moving of movable voussoir that can not realize safety tongs in time.Promptly this scheme can not timely well stop car.
Summary of the invention
The present invention is directed to the deficiency of prior art, a kind of shift mechanism of safety tongs is provided, its movable voussoir that can carry out in time in the safety tongs pincers seat moves, thereby realizes the mechanical stop of car.In addition, the present invention is simple in structure, and operation is convenient.
For realizing above timely purpose, the present invention will take following technical scheme:
A kind of shift mechanism of safety tongs comprises pull bar and is installed in the draw bar Connection Block on the pull bar, and near the body of rod said pull bar one end is arranged to screw rod, and screw rod is locked with the mode that is threaded and lifted piece; The other end of pull bar is captive joint tie rod plate then; Lift simultaneously draw bar Connection Block, positioning plate and two wire rope grips that are provided with at interval are installed on the pull bar between piece and the tie rod plate in proper order.
Spacing in twos between said positioning plate and the two wire rope grip threes equates.
Said draw bar Connection Block comprises sheath, angle-shaped piece and connecting panel, and sheath is socketed on the body of rod of pull bar, and connecting panel is installed on the pull bar through sheath, and angle-shaped piece is then captiveed joint through the mode of welding with connecting panel.
It is the rubber making of 55-60 that sheath adopts shore hardness.
According to above technical scheme, can realize following beneficial effect:
The present invention is arranged to the screw-type connector with an end of pull bar so that with lift piece and be connected; The present invention is provided with the draw bar Connection Block on pull bar, so that pull bar is linked into an integrated entity with the draw bar that is used to be connected governor rope; The present invention also is provided with wire rope grip on pull bar so that governor rope can direct mount to pull bar, thereby the pulling force that can directly governor rope be provided is delivered to safety tongs; Accelerate the car stop.In addition, the present invention is provided with positioning plate on pull bar, to prevent wire rope grip under the tension of governor rope, makes significantly and moving.
