High-strength lifting lug for elevator box

Abstract

The invention relates to the technical field of elevator lifting, and discloses a high-strength lifting lug for an elevator box. The high-strength lifting lug comprises a bearing plate, wherein two reinforcing rods penetrating through the bearing plate are fixedly installed inside the bearing plate, first nuts are in threaded connection with the outer sides of the reinforcing rods and located above the bearing plate, limiting plates are fixedly installed on the tops of the first nuts, second nuts are in threaded connection with the tops of the limiting plates and located on the outer sides of the reinforcing rods, and gaskets are fixedly installed on the outer sides of the two reinforcing rods and located at the bottom of the bearing plate. According to the high-strength lifting lug for the elevator box, by arranging a rotating shaft, a bearing and a rolling wheel, a steel cable lifting rope is in direct contact with the outer side of the rolling wheel inside the lifting lug, a concave groove is formed in the outer side of the rolling wheel, the radius of the concave groove is larger than the diameter of the steel cable lifting rope, direct friction between the steel cable lifting rope and the lifting lug can be reduced in the lifting process of an elevator, and the purpose of reducing friction between the lifting lug and the steel cable rope is achieved.

Description

technical field [0001] The invention relates to the technical field of elevator lifting, in particular to a high-strength lifting lug for an elevator box. Background technique [0002] Among the many conveyor accessories, the lifting lug is an indispensable part in lifting and transportation operations. It is the main lifting point structure and is directly related to the safety of large-scale equipment lifting. Therefore, it requires good load-bearing capacity and stability. It It can be trusted because its lugs are of good quality, not easy to deform, and have strong corrosion resistance. [0003] During the lifting process of the elevator, there is direct friction between the lifting lug and the steel cable. During the friction process, the outer wall of the lifting lug or the outer wall of the steel cable will be greatly damaged, which will increase the hidden danger of the elevator and easily cause elevator failure. , causing accidents, so a kind of lifting lug with hi...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high-strength lifting lug for an elevator box, which has the advantages of reducing the friction between the lifting lug and the steel cable, and solves the problem of direct friction between the lifting lug and the steel cable during the lifting process of the elevator. In the process of friction, the outer wall of the lifting lug or the outer wall of the steel cable will be greatly damaged, which will increase the hidden danger of the elevator, easily cause elevator failure, and cause accidents.
