Horizontal centrifugal pump alignment device

The utility model relates to the technical field of horizontal centrifugal pumps, in particular to a horizontal centrifugal pump alignment device which comprises a connecting seat and a hollow column, the outer wall of the connecting seat is fixedly connected with the end of the hollow column, the interior of the hollow column is slidably connected with the outer wall of a first sliding column, the end of the first sliding column is fixedly connected with the outer wall of a fixing seat, and the end of the fixing seat is fixedly connected with the outer wall of the fixing seat. Mounting holes are formed in the fixing seat, and the number of the mounting holes is two. A handle in the adjusting device drives a rotating plate to rotate, the rotating plate drives a double-end stud to rotate, the double-end stud drives threaded blocks to move, the two threaded blocks move relatively, the two threaded blocks slide in a second sliding column, and the two threaded blocks drive connecting pieces to move, so that the d
