Description

Technical Field

[0001] The utility model belongs to the technical field of blast furnace maintenance, and particularly relates to a two-purpose ground crawler tooling for replacing the slag granulation rotary drum of a blast furnace. Background Technique

[0002] In modern blast furnace ironmaking production, blast furnace slag is one of the main by-products of blast furnace ironmaking. The treatment of blast furnace slag can be mainly divided into dry slag and water slag. The production of water slag has high economic value, is widely used, and is conducive to the rational utilization of resources, and has become the main method for treating blast furnace slag. Due to the advantages of compact layout, small floor area, automation of the whole process, and good quality of water slag in the dehydration of rotary drum water slag, various rotary drum water slag processes have been widely used in the production of water slag in large and medium-sized blast furnaces.

[0003] In the actual application process, the slag granulation rotary drum plays a crucial role in the ironmaking process. There are many on-site transmission devices and the environment is poor. The rotary drum may stop rotating, become blocked, get stuck, slip, etc. due to malfunctions, abnormal operations, mechanical damages, etc. of the transmission devices in any of the above links. If the operators cannot discover it in time, it will affect the normal production of the water slag system, cause the transmission devices of the rotary drum to be overloaded or damaged by large impacts, resulting in great economic losses.

[0004] Therefore, the replacement of the rotary drum is often organized as the main line. At the same time, there are many restrictive conditions at the construction site during the actual disassembly and installation process. For example, the site is limited, large cranes cannot stand, the construction cost of using extra-large cranes is relatively high, the elevation of the structure is relatively low, and the diameter of the rotary drum (D5000×6250mm) plus the height of the trailer (1200mm) exceeds the elevation of the structure, making it impossible to complete the transfer, and the installation difficulty is relatively large.

There is a jack seat on the outside of each of the four corners of the rectangular welded frame, and a limit post is provided at each of the four corners of the rectangular welded frame. The tops of the symmetrically arranged limit posts on the left and right are provided with inclined surfaces or arc surfaces that face each other left and right, and the inclined surfaces or arc surfaces match the outer contour of the blast furnace slag granulation drum; the outer contour of the base matches the drum transportation flat car.
