Embodiment Construction

[0028] The specific implementation of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

[0029] Such as Figure 1 to Figure 5 The structure of the present invention shown is a lifting device for lifting and lowering the steel ladle by adding a cover mechanism to realize balanced lifting, including bearing blocks 2, oil cylinder connecting rotating arms 1, multiple frame connecting rotating arms 5 and rotating shafts 10 respectively arranged on both sides of the steel ladle. , the oil cylinder is connected to the rotating arm 1 and is fixedly connected to the rotating shaft 10, and the rotating shaft 10 is supported and installed on the bearing seat 2. The bearing seat 2 is fixedly installed on the lift frame guide fram...

Abstract

The invention discloses a lifting device of a steel ladle flip cover adding mechanism. The lifting device of the steel ladle flip cover adding mechanism comprises bearing seats respectively arranged on two sides of a steel ladle, an oil cylinder connecting rotary arm, multiple rack connecting rotary arms and rotary shafts, wherein the oil cylinder connecting rotary arm is fixedly connected with the rotary shafts, and the rotary shafts are supported by the bearing seats. A torsion balance shaft is arranged between two bearing seats, and two ends of the torsion balance shaft are coaxially, respectively and fixedly connected with two rotary shafts. The rack connecting rotary arms are arranged on the torsion balance shaft. The invention further discloses an operating method of the lifting device. By adopting the technical scheme and due to the effect of the torsion balance shaft, even if the acting forces input by oil cylinder push rods at two ends are unbalanced in a large range, a connecting rod on the torsion balance shaft can still drive a lifting mechanism to perform whole synchronous lifting motion, and lifting frame inclination, shaking and collision, even stuck situation and other severe device accidents caused by asynchronous hoisting device operation are completely eradicated. Therefore, the lifting device is safe, reliable and simple and convenient to manufacture and maintain.

Description

technical field [0001] The invention belongs to the technical field of metallurgical industry production equipment, and relates to steelmaking process equipment technology. More specifically, the present invention relates to a lifting device for a ladle uncovering mechanism. In addition, the invention also relates to the operating method of the device. Background technique [0002] The ladle capping device is the core equipment in the whole ladle capping system. It has a good energy-saving effect and has been widely used. However, the equipment layout of most steel plants is very compact and the space for renovation is limited. [0003] In order to save space, the ladle uncovering device in the prior art generally adopts the lifting mode of independent jacking mechanisms on both sides. Due to the asynchronous operation of the hoisting equipment, the movable frame of the hoisting device is prone to inclination during operation, causing vibration and collision, and even jamm...
