Description

Technical Field

[0001] The utility model belongs to the technical field of petrochemical equipment, and in particular relates to a tool used for replacing petroleum equipment. Background Art

[0002] At the process site, horizontal overlapping equipment is usually used due to factors such as floor space. Taking horizontal heat exchangers as an example, horizontal heat exchangers are widely used in industrial fields such as petrochemicals, electricity, environmental protection and refrigeration. They are connected in parallel or in series to increase the processing capacity or higher heat exchange requirements. After a period of use, the heat exchanger needs to be repaired or replaced, but the horizontal overlapping heat exchanger is difficult to replace due to its limited space and heavy weight.

[0003] The existing horizontal overlapping equipment maintenance method is:

[0004] (1) Make a steel structure to fix the upper equipment and stabilize the upper equipment support; (2) When the upward lifting space of the equipment body is limited, after reinforcing the support of the lower equipment, lift the entire equipment, set up a translation device at the bottom, and then make an arc cut on the base of the lower equipment to lower the height of the equipment and create the space required for translation; use multiple fall chains to rotate the lower equipment 30° along the axis to avoid the parts that affect each other between the equipment's own pipelines, the upper equipment and the cement foundation. When resetting, use the opposite procedure to return to the original path to achieve re-positioning. When using multiple fall chains, multiple people manually operating are prone to uneven force and lifting injuries. Utility Model Content
