Abstract
The invention creatively provides a pull arm of an elevator safety gear. The pull arm comprises a pull arm body and a sleeve at one end of the pull arm body, wherein the pull arm body comprises a first connecting part and a second connecting part, and a bent part is arranged between the first connecting part and the second connecting part; a first connecting hole is a long hole; four to six positioning holes are distributed in the sleeve in the circumferential direction; and the inner surface of the sleeve is coated with a self-lubricating material or is provided with a self-lubricating bearing. The pull arm of the safety gear is reasonable in structural design. A through hole is further formed in the second connecting part, so that positioning and connection can be facilitated, and the stress concentration of the pull arm body at the second connecting part is effectively reduced. The sleeve is welded on the pull arm body, so that the structure is stable and reliable. By usually adopting fillet welding, the height of weld beads is 1mm. The outer surface of the pull arm body is coated with an anti-oxidation layer so as to ensure that the pull arm body has great oxidation resistance and corrosion resistance and is durable.
