Load-lifting device for maintaining and hoisting continuous casting withdrawal and straightening machine

Abstract

The invention discloses a load-lifting device for maintaining and hoisting a continuous casting withdrawal and straightening machine. The load-lifting device is characterized by comprising a hanging beam; the hanging beam is provided with a hanging hole plate; the hanging hole plate is provided with a hanging hole; and hanging hooks used for hooking a withdrawal and straightening machine hoistingshaft is arranged below the hanging beam. The special hoisting tool for maintaining and hoisting a continuous casting withdrawal and straightening machine is used for specially hoisting a bloom casteror a round billet caster withdrawal and straightening machine for online mounting, offline maintenance and care and offline transportation to different positions, is convenient for an equipment maintenance person to safely and stably hoist the withdrawal and straightening machine, avoids the trouble of an operator to frequently climb for threading a hoisting steel wire rope, completely eradicatesthe safety hidden dangers in the maintenance process, greatly shortens the withdrawal and straightening machine hoisting and maintenance operation time, reduces the labor intensity and improves the maintaining and hoisting operation efficiency.

Description

technical field [0001] The invention belongs to the technical field of hoisting, and more specifically relates to a hoisting tool for overhauling and hoisting a continuous casting tension leveler. Background technique [0002] Today, with the advancement of continuous casting technology, bloom and round billet continuous casting machines generally adopt multi-stream design, integrated frame-type billet drawing and straightening equipment, with a single weight of about 10 tons and a relatively large dead weight. With the application of new technologies such as pressing, the geometric dimensions and body strength of the tension leveling machine are designed with a large margin, and the number of tension leveling machines per stream also tends to increase, at least 5 sets, so the number of online tension leveling machines is relatively large. There are many equipment maintenance personnel to replace the online tension leveler, and the off-line tension leveler is out of luck and...

Problems solved by technology

[0002] Today, with the advancement of continuous casting technology, bloom and round billet continuous casting machines generally adopt multi-stream design, integrated frame-type billet drawing and straightening equipment, with a single weight of about 10 tons and a relatively large dead weight. With the application of new technologies such as pressing, the geometric dimensions and body strength of the tension leveling machine are designed with a large margin, and the number of tension leveling machines per stream also tends to increase, at least 5 sets, so the number of online tension leveling machines is relatively large. There are many equipment maintenance personnel to replace the online tension leveler, and the off-line tension leveler is out of luck and the frequency of displacement has also increased a lot. Every time the maintenance personnel need to arrange 2 people to climb the tension leveler to hang steel wire ropes, locks and other hoisting equipment, and work at heights , and there are generally oil, water and other sundries on the equipment body of the on-site tensioning and leveling machine. If the operator is a little distracted, it is easy to slip and fall, which has potential safety hazards and brings inconvenience to equipment maintenance and repair. At the same time, the labor intensity is also relatively high.
