AI Technical Summary

Problems solved by technology

The installation of the centering work of the bridge frame and the installation center line of the upper grinding plate is cumbersome. In addition to the vertical line calibration that needs to be pulled up and down multiple times, it is also necessary to set up a benchmark center point of the same elevation in the distance as a reference for calibration, and the installation period is long.

Embodiment

[0067] 1. Positioning of the vertical mill base: the center point is based on the major axis of the civil engineering construction drawing, and according to the degree distribution of each base column in the installation drawing, the center line of the three bases and the main motor is determined with theodolite, and the "roller Vertical vertical mill centerline vertical moving installation device "accurately moves the centerline vertically above the bearing seat of the base to ensure that it coincides with the centerline of each base.

[0068] Second, the installation of the basic frame

[0069] Pre-assemble the basic frame on the assembly platform without welding first to check the difference between the actual object and the drawing before installing the basic frame. Before installing the basic frame, the following points should be noted: the specific positions of all jacking wires in the foundation pit , put the anchor bolts in the reserved holes of the foundation; res...

Abstract

The invention relates to a roller type vertical mill installation method, which belongs to the mechanical equipment installation method. The installation sequence comprises the following steps: positioning a vertical mill pedestal, installing a basic framework, installing a pedestal, installing a bridge frame, secondary casting concrete, adjusting a speed reducer base plate and glue-casting and positioning, installing a mill speed reducer, installing a grinding table, installing a mill body, installing a main roller, installing a powder separator, installing a speed reducer lubricating system and installing a mill main motor. The invention has the advantages that the construction technology possesses good effect, the benefit is substantial, one time qualification rate of welding 622t, X-ray flaw detection shooting can reach more than 99.95%, and the qualified rate of random sampling welded junction shooting can reach 99%. The method of the invention is capable of acquiring a lot of important construction technical data, and accumulating valuable experience for installing subsequent same kind equipments.

Description

technical field [0001] The invention belongs to a mechanical equipment installation method, in particular to a roller vertical mill (LM53.3+3CS) installation method. Background technique [0002] Roller vertical mill (LM53.3+3CS) is the core equipment for slag micro-powder processing to improve the durability of cement base materials. The technical difficulty of installation is relatively high. The main equipment is the vertical roller mill produced by Loesche Company in Germany, and the other ancillary equipment adopts equipment from domestic manufacturers with advanced production technology designated by Loesche Company. The total weight of the whole set of equipment is 713 tons (including 91 tons of reducer and 85 tons of grinding disc including mill liner). Since the main reducer of the vertical roller mill weighs 91 tons and is installed in the middle below the three bridges supporting the grinding disc, the three bridges are as high as 8m. The installation of the cen...
