Positioning device for replacing analog sampling cooler

The utility model belongs to the technical field of pipeline installation and positioning, and particularly relates to a positioning device for replacing a simulation sampling cooler, which comprises a base plate, angle steel, a side plate arranged on the side surface of the angle steel, a cover plate arranged at the end part of the angle steel, a reinforcing rib plate arranged on the base plate, a vertical pipe arranged on the cover plate, a flange arranged on the side plate and a tee joint arranged at the lower part of the side plate, the multiple sets of angle steel are welded to form a box body structure. By arranging the angle steel, the side plates, the cover plates, the flanges and the tee joints and replacing the positioning device of the simulation sampling cooler, under the condition that the sampling cooler does not arrive, the sampling cooler is reduced in a 1: 1 mode, the replacement sampling cooler positions pipeline installation and participates in follow-up cleaning, purging, pressure testing
