Abstract

The invention discloses a fixing method for a vertical shaft pull rod protection cover, which is used for mounting the vertical shaft pull rod protection cover on a vertical shaft pull rod. The fixing method comprises the steps of fixing two ends of the vertical shaft pull rod on a lower vertical shaft bearing pedestal and a vertical mill shell respectively through flower basket bolts; then adjusting the flower basket bolts to level the a vertical shaft; tightly laminating a lining plate with a V-shaped cross section on the pull rod so as to enable the outer surface of the pull rod to be in tight contact with two surfaces of the lining plate; finally enabling the outer surface of the pull rod to press against a steel plate connection piece, and welding the steel plate connection piece to two ends of the lining plate. According to the fixing method provided by the invention, the vertical shaft pull rod protection cover consisting of the V-shaped lining plate and the steel plate connection piece is arranged outside the vertical shaft pull rod instead of being welded on the shell and the lower bearing pedestal, and the pull rod is not welded any more, so that side effects on the levelness of the vertical shaft pull rod is avoided; meanwhile, the welding workload is reduced, the operation is simplified, and the efficiency is improved. The invention also provides the vertical shaft pull rod protection cover.

Description

technical field [0001] The invention relates to the technical field of cement equipment, and more specifically, relates to a fixing method for a vertical shaft tie rod shield, and also relates to a vertical shaft tie rod shield. Background technique [0002] Vertical mill is an ideal large-scale grinding equipment, which is widely used in cement, electric power, metallurgy, chemical industry, non-metallic minerals and other industries. [0003] During the installation and construction of vertical mill equipment, the vertical shaft pull rod shield is directly connected to the pull rod by welding, and the two ends of the vertical shaft pull rod shield are respectively welded to the shell and the lower bearing seat. This method is not only labor-intensive and time-consuming, but also inconvenient to operate and low in efficiency. The direct welding operation on the pull rod will affect the levelness of the vertical shaft, which is not conducive to the alignment of the vertical ...
