Problems solved by technology

The weight of the equipment is heavy, and it is in high-altitude construction, which has high safety risks. At the same time, the production of spreaders is labor-intensive and time-consuming, and the construction cost is high
Due to the use of double-machine lifting, the bridge crane that receives the molten steel span is occupied, which affects the normal production of the steelmaking workshop

Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] Such as figure 1 and figure 2 as shown,

[0044] 1. A method for replacing bearings of a bale turntable, comprising the following steps:

[0045] Step 1: Protective removal of associated equipment and preparation of auxiliary pillars:

[0046] 1.1) Disassemble the brake disc, gear guard and transmission motor reducer, and cut the horizontal guard that interferes with the installation position of the pillar;

[0047] 1.2) Disassemble the slip ring and rotary oiler in the base, disassemble the limit position, and dismantle the connecting bolts of the bearing and the base as required;

Abstract

The invention discloses a method for replacing the bearing of a large ladle turret. The method comprises the following steps of detaching associated devices for a protective purpose and preparing an assisted strut, jacking the upper device of the large ladle turret, replacing the bearing of the large ladle turret, lowering the upper device down, and recovering the detached device. The method for replacing the bearing of the large ladle turret only relates to the basic process of setting a hydraulic jack, the upper device on the large ladle turret does not need to be detached, dedicated lifting appliances are not needed, a molten steel receiving bay crane is not needed, and a large-scale trunk crane does not need to be rent, and normal equipment production in a molten steel receiving bay is not influenced. The method for replacing the bearing of the large ladle turret is safe, reliable, saving in cost and capable of shortening construction period greatly.

Description

technical field [0001] The invention relates to a method for installing continuous casting machine equipment, in particular to a method for replacing a rotary bearing of a ladle turntable in a continuous casting system. Background technique [0002] The ladle turret is one of the main equipment in the continuous casting machine system. The long-term load operation makes the rotating bearing need to be disassembled and replaced. Since the bale turntable is designed under the track beam, the bearing of the turntable is installed between the base and the rotary body, and the equipment on the bearing usually has more than 100 tons. [0003] The traditional bearing replacement method is as follows: design and manufacture a special spreader, use two bridge cranes for the molten steel receiving span and the casting span to cooperate with tools such as chain down to lift and disassemble the yoke, jacking hydraulic cylinder, slewing body, etc. Equipment, or use a large-scale truck c...
