Lifting appliance for installing rolling mill housing and system thereof

Abstract

A lifting appliance for installing a rolling mill housing comprises an upper lifting lug and a lower lifting lug. The upper lifting lug comprises two connecting plates, wherein the surfaces of the connecting plates are parallel. A top plate and a bearing plate are arranged between the connecting plates from top to bottom at intervals. Through holes are formed in the middle of the top plate and the middle of the bearing plate. Lugs are arranged at the bottoms of the connecting plates. The lower lifting lug is a plate body which is reversely T-shaped. The upper portion of the reversely T-shaped plate body is hinged to the lugs. A cross rod at the bottom is connected to an oil cylinder hole in the head of a rolling mill housing in a clamping mode. The lifting appliance is simple in structure and easy and convenient to assemble and disassemble.

Description

technical field [0001] The invention relates to a sling, in particular to a sling for installing a rolling mill archway and a system thereof. Background technique [0002] With the development of the industry, the weight and structural size of the rolling mill archway are getting larger and larger, and are limited by various reasons such as the height of the factory building. The crane lifting scheme is more and more restricted by the environment. Existing hoisting gear for rolling mill archway includes ring wire rope, hanging concrete, pulley, bearing pin, and hanging concrete is columnar, and its lower part has a through hole, and bearing pin is worn in the hole, and two pulleys are additionally set on the bearing bearing, and on the pulley All are covered with ring-shaped steel wire ropes; the above-mentioned spreader is not suitable for moving, flipping, lifting, etc. the archway in a narrow space, and cannot solve the construction problem when the conventional crane can...
