Embodiment Construction

[0017] As shown in the figure: Part No. 1 is the base of the rolling mill to be installed, and each rolling mill is composed of two bases on the entrance and exit sides. The center target plate 2 is measured and set by the total station, and the target plate buried around the rolling mill base in advance is the benchmark basis for the center line and parallelism measurement of the rolling mill base. The precision level 3 is a measuring instrument used to measure the levelness of the rolling mill base. The elevation reference point 4 is measured and set by the total station, and the reference points buried around the rolling mill base in advance are the basis for the elevation measurement of the rolling mill base. The indium ruler 5 is a measuring tool for measuring the height of the rolling mill base with a precision level. The inner diameter micrometer 6 cooperates with the theodolite to measure the center line and parallelism of the rolling mill base. The frame level meter...

Abstract

Disclosed is an accurate installation measuring method for rolling mill bases. The accurate installation measuring method includes the following steps that (1) two transverse center line center standard plates and two longitudinal center line center standard plates are buried around the rolling mill bases in advance; (2) elevation datum points are buried around the rolling mill bases in advance; (3) horizontal brackets are placed on the two bases on the inlet side and the outlet side of a rolling mill correspondingly, and inside micrometers are placed on the horizontal brackets; (4) theodolites are used to cooperate with the inside micrometers placed on the horizontal brackets so as to measure the longitudinal and transverse center lines of the rolling mill bases; (5) a precise level is used to cooperate with indium light rulers for elevation measurement of the rolling mill bases; (6) frame level meters are adopted to measure levelness of the rolling mill bases; and (7) measurement of degree of parallelism of the rolling mill bases is performed. By means of the accurate installation measuring method for the rolling mill bases, the measuring accuracy of the center lines, elevation, levelness and degree of parallelism of the rolling mill bases can be greatly improved, the measuring speed is high, the equipment installation progress can be greatly improved, and therefore, the construction cost is greatly reduced.

Description

Technical field: [0001] The invention belongs to the field of mechanical equipment installation in the metallurgical industry, and in particular relates to an accurate measurement method for the installation of a rolling mill base, which is applicable to the measurement of the installation of the base of mechanical equipment of the same type including a temper mill and a punching machine. Background technique: [0002] The installation quality of the rolling mill base directly determines the installation accuracy of the entire rolling mill, and even determines whether the rolled products are qualified or not. Therefore, the installation accuracy of the rolling mill base is particularly important in the installation process of the entire rolling mill equipment. At present, the installation center line of the rolling mill base is determined by the method of drawing steel wire and hanging hammer together with the steel ruler measurement method, and the measurement and design of...
