Example Embodiment
[0048] Example 1: Such as figure 1 As shown, the portable trolley for replacing the current transformer includes two mutually articulated frame 1 with a guide rail 7 provided on the frame 1 and a lifting device is slidably connected to the guide rail 7.
[0049] The frame 1 includes two No. 4 angle steels, the middle part is connected by three reinforcing ribs 14, and the outer end is connected by steel pipes. Of course, the frame 1 may also have other shapes such as a concave shape and an I-shape.
[0050] The selection scheme of guide rail 7 is shown in Table 2:
[0051] Choice of guide rail
[0052]
[0053] It can be seen from the above table that the technical effect of Scheme 2 is the best, which can bear the weight of the lifting device without deformation; and the current transformer moves flexibly on the guide rail 7 during transportation, and there is no jam during the forward process.
[0054] Such as figure 2 As shown, the bottom of the frame 1 is provided with a number o...
