Description

Technical Field

[0001] The invention relates to the field of flat rail replacement equipment and methods, and in particular to a flat rail replacement equipment and method inside a hot air hood of a sintering machine. Background Art

[0002] The flat rails of the sintering machine need to be replaced regularly due to wear. The flat rails are heavy (the length of a single flat rail is about 8m and the weight is about 500kg). A hot air hood was added after the sintering machine was modified, but the internal space of the hot air hood is small, which makes it inconvenient to transport the flat rails inside the hot air hood, which is difficult and labor-intensive.

[0003] When there is no hot air hood, the flat rail can be directly lifted to the installation position by a crane for replacement. At present, it is impossible to use a crane for direct lifting after the modification. If multiple guide chains are used to horizontally replace the flat rail in and out of the hot air hood, the efficiency and safety of the guide chain replacement operation are relatively low because the personnel inside the hot air hood have no ideal standing position, which is easy to cause personnel squeeze injury accidents. Therefore, it is a technical problem that technicians in this field need to solve to propose a flat rail replacement device and method inside the hot air hood of a sintering machine. Summary of the invention
