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.

    本发明涉及电梯升降技术领域,且公开了一种电梯箱体用强度高的吊耳,包括承重板,所述承重板的内部固定安装有数量为两根且贯穿承重板的加固杆,所述加固杆的外侧且位于承重板的上方螺纹连接有第一螺母,所述第一螺母的顶固固定安装有限位板,所述限位板的顶部且位于加固杆的外侧螺纹连接有第二螺母,两根所述加固杆的外侧且位于承重板的底部固定安装有垫片。该电梯箱体用强度高的吊耳,通过设置转轴、轴承和滚轮,使得钢缆吊绳在吊耳的内部与滚轮的外侧直接接触,设置滚轮的外侧开设有凹形槽,凹形槽的半径大于钢缆吊绳的直径,可以钢缆吊绳在电梯的升降过程中减少与吊耳发生直接摩擦,达到了减少吊耳与钢缆绳摩擦的目的。
