Description

The invention relates to the transportation of large-scale installations and can be used in the aluminum smelters of the industry in the electrolysis and overhaul of electrolyzers for transporting the cathodes of aluminum electrolyzers.

The purpose of the invention is the elimination of deformations of the cargo by equalizing the load-carrying unit.

Figure 1 shows a lifting beam, mainly for lifting and transporting the cathode of an aluminum electrolysis cell; in fig. 2 - view A on fng.1; in fig. 3 is a section BB in FIG. in fig. 4 - section bb In figure 1; in fig. 5 - section GG in figure 1; in fig. 6 - node 1, figure 1; in fig. 7 is a view of D in FIG. Fig.8 section EE of Fig.6.

The lifting beam, mainly dp for lifting and transporting lengthy structures, includes two longitudinal beams I, a transverse beam 2, and a hook 3 for the load hook. On the sides of the Kashda longitudinal beam 1, blocks 4 are installed on axles 5 and blocks 6 on axes 7, and on axes 7 there are rollers 8 mounted in directions 9, rigidly connected with longitudinal beams 1. Axes 7 with blocks 6 are also combined from two sides by rods 10. Thus, two pairs of guides 9, symmetrically arranged, are rigidly attached to the outer side surfaces of the longitudinal beams 1.

relative to the vertical axis of the suspension, in which are mounted with the possibility of longitudinal movement of the gi 10, made in the lower part with 1fingles 11, between which are pre-compressed glands 12, contacting with brackets 13 rigidly connected with the longitudinal beams 1, and the springs 12 are installed on axles 14, which, in turn, are rigidly connected with brackets 11 tons of 10, with between each pair of guides 9 left and right relative to the vertical axis of the suspension are mounted on axis 7 rollers 8 and blocks 6 for cables 15 .Kazh And a pair of blocks 4 and 6 are connected by cables 15 with fasteners 16 to subcathode beams 17 with cathode 18.

The cathode 18 is mounted by supports 1 9 on subcathode beams 17 with fasteners 16. The traverse is moved with a bridge crane to the installation zone of the cathode 18. When the traverse is lifted by the bridge crane, the loads from the weight of the cathode 18 are perceived by cables 15, the length of which is equalized due to the longitudinal movement of blocks 6 with tgami 10 and brackets 11 in one direction or another, and compressing the springs 12 and the brackets 13 of the axles 14.

In this case, the cables 15 move the blocks 6, and they move the cables 10, which with their brackets 11 with the axles 14 additionally compress the pre-compressed springs 12, limiting the movement of the blocks 6.
