Description

Method for adjusting center of gravity of prefabricated cabin and auxiliary device Technical Field The invention belongs to the field of prefabricated cabin hoisting, and particularly relates to a method for adjusting the gravity center of a prefabricated cabin and an auxiliary device. Background The prefabricated cabin is used as a prefabricated substation electrical equipment carrier and has an unobtainable important position in a power grid, the prefabricated cabin has the technical characteristics of standardization, modularization and prefabrication, a manufacturer can correspondingly customize a specific size according to the actual needs of an equipment cabinet body so as to adapt to the installation and operation of electrical equipment to be arranged, and as a result, the application requirements of the prefabricated cabin are rapidly increased along with the acceleration of the construction pace of the intelligent power grid. The prefabricated cabin is applied by first installing a plurality of predetermined electrical devices therein and then transporting and hoisting the prefabricated cabin to a predetermined place. However, in specific practice, the above-mentioned manner has the disadvantages that the arrangement positions of a plurality of preset electric devices in the prefabricated cabin are mostly deviated to one side in normal operation due to electric arrangement requirement, so that the gravity center of the prefabricated cabin is not positioned at the central position of the prefabricated cabin but is deviated to one side, and thus, in the transportation process, the risk of slip capsizing exists, the gravity center of the prefabricated cabin cannot be rapidly determined for hoisting during hoisting, and once the determined gravity center of the prefabricated cabin is not the actual gravity center thereof, serious hoisting accidents are caused. Disclosure of Invention Aiming at the defects of the prior art, the invention provides a method for adjusting the center of gravity of a prefabricated cabin and an auxiliary device thereof, which can quickly adjust the center of gravity of the prefabricated cabin to a preset position, thereby eliminating the related risks caused by the deviation of the center of gravity to one side in the transportation and hoisting processes. In order to achieve the above purpose, the present invention provides the following technical solutions: A method of adjusting the center of gravity of a prefabricated compartment having a base support and having a plurality of predetermined electrical equipment therein, comprising the steps of: Step S1, movably arranging an equipment bearing plate on a base bracket so that preset electric equipment is positioned on the equipment bearing plate; S2, moving the equipment bearing plate to a preset middle position, and mechanically positioning the equipment bearing plate on the base bracket; and S3, removing the mechanical positioning and moving the equipment bearing plate to a preset final position.
