[0045] The lifting mechanism 3 is used to lift the cabinet, that is, to provide a vertical upward pulling force for the cabinet so as to carry out the lifting and windproof test of the cabinet. The lifting mechanism 3 is slidably arranged on the guide rail 2; one end of the guide rail 2 is located inside the main frame 1, and the other end is located outside the main frame 1 and is spaced apart from the outside, that is, the outer end of the guide rail 2 located on the main frame 1 extends a distance on the side of the main frame 1; when the cabinet is tested, it needs to be installed and fixed with the lifting mechanism 3, such as Figure 1As shown, since the guide rail 2 passes through the outside of the main frame 1, when installing the two, the lifting mechanism 3 can be moved to the outside of the main frame 1 first, and the cabinet and the lifting mechanism 3 can be installed, and then the lifting mechanism 3 and the cabinet can be moved into the main frame 1 to perform subsequent tests on the cabinet. During this period, the operating space for connecting the cabinet and the lifting mechanism 3 is relatively large, which can not only avoid interference and collision between the cabinet and other components in the test device, but also allow the cabinet to be moved and coordinated with the help of other large tools, thereby improving the convenience of installation operations of the cabinet and the lifting mechanism 3.

Then, the first electric cylinder 32 is extended and retracted to repeatedly apply a vertical upward lifting force to the cabinet. The lifting performance of the cabinet can be judged according to the test conditions of the cabinet. The preset value of the lifting force is three times the weight of the fully loaded cabinet and is not greater than 12000N. When the value of the first tension sensor 34 is equal to the preset value of the lifting force, the lifting force is maintained for a period of time, specifically more than 30 seconds.
