Problems solved by technology

[0002] The grinding roller is the key equipment in the raw material grinding process of the cement plant, and the base is the basis for the installation of the grinding roller, so the installation and construction accuracy of the grinding roller base directly affects the installation accuracy of the grinding roller; the installation of the existing grinding roller base, in the grouting During the process, the base is prone to deviation, and because the keel at the bottom of the base is separated, the grouting material between the adjacent grids of the grid-shaped keel frame cannot flow, resulting in hollowing, which will affect the installation quality of the roller base. And then affect the installation quality of the grinding roller, which is undesirable for those skilled in the art

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0030] Such as Figure 1~6 As shown, the present invention discloses a method for installing and constructing a raw material grinding roller base. The grinding roller base includes a bottom plate 1 and a grid-shaped keel frame 2 fixed on the bottom of the bottom plate 1, and the bottom plate 1 is provided with adjusting bolts 4 , hydraulic bolt holes 12, air outlet holes 13 and grouting holes 11, specifically, the method comprises the following steps:

[0031] Step S1, cutting the keels in the grid-shaped keel frame 2 at the bottom of the grinding roller base to form cutting holes 21, so that adjacent grids of the grid-shaped keel frame 2 are connected.

[0032] In the embodiment of the present invention, after the cutting holes 21 are formed, iron wires are passed through the cutting holes 21 ...

Abstract

The invention relates to the technical field of building construction, and particularly relates to an installation and construction method of a grinding roller base of a raw material grinding mill. The installation and construction method comprises the following steps that keels in a latticed keel frame at the bottom of the grinding roller base are cut to form cutting holes before hoisting, so that the fluidity of grouting materials is increased; therefore, the hollowing phenomenon of the grinding roller base due to the fact that the grouting materials cannot flow can be avoided, after the grinding roller base is hoisted, the elevation and the horizontal position of the grinding roller base are adjusted by using an adjusting bolt and a jack, and then the grinding roller base and a metal corrugated pipe are welded and fixed together through an iron plate, so that the situation that the base deviates in the grouting process is prevented, after the grinding roller base is grouted, holes are drilled in the center area and corners of the grinding roller base to form a plurality of grouting holes, and then grouting is carried out on the grinding roller base by using the grouting holes. According to the construction method, the safety, the controllability and the economical efficiency are fully considered, a foundation is laid for hoisting of a grinding roller, and compared with the other construction modes needing to solve the problem, the construction method is fewest in investment, convenient to operate, safe, reliable and high in practicability.
