Problems solved by technology
The traditional converter tilting installation system adopts separate installation, and the assembly and lifting of the tilting device on site requires a lot of labor and delays the construction period
Moreover, both the converter and the tilting device are heavy-duty equipment. The gap between the tilting device and the converter across the trunnion connection is very small, and the installation accuracy is high. It is difficult to control the level of the tilting device during the split hoisting process, and the installation process takes a long time.

Embodiment Construction
[0015] In order to fully understand the purpose, features and effects of the present invention, the present invention will be described in detail through the following specific embodiments, but the present invention is not limited thereto.
[0016] Such as figure 1 As shown, a kind of steelmaking converter provided by the present invention and the method for integrally pushing and installing the tilting device are carried out according to the following steps:
[0017] Step 1. According to the tonnage of the converter body 3 and the tilting device 4, the converter support 1 is designed. The converter support 1 is preferably an isosceles trapezoidal structure, such as figure 2 shown. And use Midas software to calculate whether the converter support 1 can reach the safety factor and the expected bearing capacity. The converter bracket 1 is assembled on the straddle car 2 on site, the converter body 3 is hoisted on the converter bracket 1, and the converter support ring is inst...

The invention discloses an integral pushing and loading method for a steelmaking converter and a tilting device, and relates to the field of installation of the steelmaking converter tilting devices. A converter and a tilting device are assembled on a converter support in advance through a converter backing ring, the converter support is placed on a straddle carrier, a lug bearing bears the main weight of the tilting device, and a charging straddle crane hoists the tilting device to keep the tilting device horizontal; a horizontal support is arranged below the tilting device and makes contact with the tilting device through a sliding piece, and therefore, safety is guaranteed, and meanwhile abrasion of the tilting device is reduced. A hoister is used for driving a straddle carrier to move, meanwhile, a charging straddle crown block drives the tilting device to follow up synchronously; the converter and the tilting device are integrally pushed and installed to the installation positions, and the tilting device does not need to be positioned again. And the leasing-off process time period not only ensures the safety of workers in the construction process, but also saves a large amount of time, shortens the construction period and improves the installation efficiency.
Description
technical field [0001] The invention relates to the field of installation of a steelmaking converter tilting device, in particular to a method for integrally pushing and installing a steelmaking converter and a tilting device. Background technique [0002] As one of the key equipment in the steelmaking process, the converter has a very high utilization rate in steel mills, and the installation of the converter is an essential link. The converter needs to be used simultaneously with the tilting device. The traditional converter tilting installation system adopts separate installation, and the assembly and lifting of the tilting device on site requires a lot of labor and delays the construction period. Moreover, both the converter and the tilting device are heavy-duty equipment. The cross-trunnion connection between the tilting device and the converter has a very small matching gap, and the installation accuracy is high. It is difficult to control the level of the tilting dev...
