Problems solved by technology

[0002] In the existing continuous casting machine, when the upper rotary body of the ladle rotary table is moved and replaced as a whole, double cranes are often used to lift and hoist, and the method of laying rail slideways uses hydraulic cylinders to move synchronously. This method is restricted by unfavorable factors such as driving installation or production coordination difficulties. installation operation
Secondly, the use of hydraulic cylinders to move synchronously requires renting special equipment, resulting in increased construction costs

Embodiment Construction

[0028] The present invention is further illustrated below by specific examples.

[0029] A method for horizontally moving the upper part of a bale turntable and lifting it into place as a whole, including

[0030] Step 1, jacking fulcrum setting;

[0031] The jacking fulcrum (2) is set under the ladle arm (1) of the ladle turret, the jacking fulcrum (2) is located on the beam (4) of the moving platform (3), and the ribs are set between the upper and lower wings of the beam (4) To improve the support strength, set up a steel column (5) under the jacking fulcrum (2) to transfer the jacking force to the lower beam (4) of the push platform (3) and evenly disperse it to the foundation platform;

[0032] Step 2. The upper rotating body is lifted as a whole;

[0033] Reinforce the ladle arm (1) of the ladle turret first, and install a rectangular billet (8) at the fixed pin shaft (7) on the top of the tower of the upper revolving body (6) so that the ladle arms (1) on both sides of...

Abstract

The invention relates to a method for horizontally pushing and integrally ejecting ejecting in place for a ladle rotary table upper-part rotary body. The method is characterized by comprising the following steps of 1, setting an ejecting fulcrum; 2, ejecting the whole upper-part rotary body; 3, putting a pushing and moving rack in place; 4, arranging a pushing support; 5, horizontally pushing the upper-part rotary body; and 6, horizontally pushing a new upper-part rotary body. According to the method, the ladle rotary table upper-part rotary body is integrally ejected, ejecting force is evenly controlled, the ejecting stroke is small, rolling friction resistance generated in the operation process of the pushing and moving rack is small, integral pushing of the ladle rotary table upper-part rotary body can be completed only through one hydraulic cylinder, compared with an existing installing method that a traveling crane is used for lifting and multi-point synchronous sliding is adopted, the method has better application and popularization value.

Description

technical field [0001] The invention relates to the technical field of installation of continuous casting equipment, in particular to a method for horizontally moving the upper part of the ladle turret and lifting it into place as a whole. Background technique [0002] In the existing continuous casting machine, when the upper rotary body of the ladle rotary table is moved and replaced as a whole, double cranes are often used to lift and hoist, and the method of laying rail slideways uses hydraulic cylinders to move synchronously. This method is restricted by unfavorable factors such as driving installation or production coordination difficulties. Install operation. Secondly, the use of hydraulic cylinders to move synchronously requires renting special equipment, resulting in increased construction costs. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects, and propose a method for horizontally moving the uppe...
