Specific embodiment
With reference to embodiment and attached drawing, the present invention is described further.
As shown in Figures 1 to 5, the present embodiment provides a kind of elevator safety gear of high safety, including safety tongs stent 1,
Fixed voussoir 2, needle roller row 3, movable wedge 4, adjusting mechanism 5, damping 6, lifting rod 8 and linkage board 7, fixed voussoir 2 are solid
Surely it is arranged on safety tongs stent 1, lifting rod 8 is placed through safety tongs stent 1 the upper surface of plate 11, and lifting rod 8 is solid with linkage board 7
Fixed connection, linkage board 7 are connected with movable wedge 4, and needle roller row 3 is arranged between fixed voussoir 2 and movable wedge 4, adjusts machine
Structure 5 is arranged on safety tongs stent 1, and is connected with fixed voussoir 2, and damping 6 is arranged on safety tongs stent 1, activity
Voussoir 4 is arranged on damping 6.
Safety tongs stent 1 includes top panel 11, lower panel 13, partition plate 14 and connecting plate 12, top panel 11 and lower panel 13
It being arranged in parallel, connecting plate 12 is arranged above between plate 11 and lower panel 13, and partition plate 14 is fixed at the inside of connecting plate 12,
