Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1-3, a safe buffer stop for elevator, including elevartor shaft 1, be equipped with diaphragm 2 in the elevartor shaft 1, diaphragm 2 and the contact of 1 inner wall of elevartor shaft, diaphragm 2 lower side wall fixedly connected with two first magnet 12, 1 lateral wall of elevartor shaft inlays and is equipped with two second magnet 13, two first magnet 12 are located directly over two second magnet 13 respectively, just to the first magnet 12 and the second magnet 13 of setting each other for homopolar, 1 inner wall of elevartor shaft is equipped with two recesses 3, two equal fixedly connected with telescopic links 5 of 3 inner walls of two recesses, the common fixedly connected with movable plate 4 of telescopic end of two telescopic links 5 that are located the homonymy, the relative lateral wall of two movable plates 4 all is equipped with the inclined plane to 1 middle part of elevartor shaft, two movable plate 4 lateral walls all through two springs respectively with two recess 3 inner wall elastic connection, four springs cup joint respectively at four telescopic link 5 lateral walls.
Be equipped with buffer gear in the elevartor shaft 1, buffer gear includes spout 9, spout 9 sets up bottom in elevartor shaft 1, sliding connection has two sliders 11 in spout 9, 9 inner wall fixedly connected with gag lever post 10 of spout, gag lever post 10 runs through two slider 11 lateral walls, stability when guaranteeing that two sliders 11 slide, two sliders 11 have the pressure spring with the relative lateral wall difference elastic connection of spout 9, two pressure springs all cup joint at gag lever post 10 lateral walls, lateral wall fixedly connected with riser 6 under 2, 6 lateral walls of riser run through and are equipped with dead lever 7, 7 lateral walls of dead lever rotate and are connected with two commentaries on classics board 8, two commentaries on classics board 8 are located the both sides of riser 6, 8 lateral walls under two commentaries on classics board rotate respectively with two sliders 11 lateral walls and are connected.
