Embodiment 1

[0039] Using the above-mentioned construction method to replace the large ring gear of the 50-ton despindle crane, it took about 6 days and a total of 24 construction workers. Because the disassembly of the clamp body assembly was reduced, the mechanical parts were basically not replaced.

Embodiment 2

[0041] Using the above-mentioned construction method to replace the large ring gear of the 40-ton despindle crane, it took about 5 days, which was about 1 day shorter than the previous replacement. No mechanical parts have been replaced.

Abstract

The invention provides an ingot drawing crane tong rotating supporting big geared ring non-lower-machine decomposition method. It includes the following steps: 1. disassembling hydraulic clip external member integrally; 2. fixing hydraulic clip external member; 3. replacing big geared ring; 4. re-installing hydraulic clip external member. Due to the decomposition method need disintegrate the clip body and whole hydraulic execution unit, so it shortens the construction period, saves the human resource cost, and reduces maintenance and construction costs.

Description

technical field [0001] The invention relates to a construction method for replacing the rotary support ring gear of the stripper tongs, which is a construction method for the rotary support ring gear of the stripper tongs without being disassembled. Background technique [0002] The demoulding workshop of the important supporting project of Baosteel's first phase project has 6 sets of the country's largest hydraulic stripping cranes imported from Japan, which are responsible for the logistics between the steelmaking plant and the cold rolling plant. The production of the factory plays an important role. Since the first phase of Baosteel's project was completed and put into production, the six tong cranes in the workshop have been operating in a high-temperature and high-dust environment, which is very harsh. Moreover, in order to meet the needs of the market, the six despindle cranes have been in high-load operation for many years, and there is a large loss to each importan...
