The specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.
[0018] See also Figure 1 and Figure 2, an auxiliary device for replacing large equipment in an electrical cabinet, comprising an electrical cabinet body 1 for placing large equipment 2, characterized in that:
[0019] See also Figure 1 , Figure 2 and Figure 3 A removable cover plate 3 is provided on the upper part of the electrical cabinet body 1. The cover plate 3 includes a symmetrical left cover plate 31 and a right cover plate 32. The bottom surfaces of the left cover plate 31 and the right cover plate 32 are respectively provided with a pair of concave guide grooves 3a. The top frame 4 of the electrical cabinet body 1 is also connected with guide rails 9. The guide rails 9 are correspondingly connected to the guide grooves 3a. The two form a sliding guide cooperation, so that the left and right cover plates slide along their respective guide rails to complete the opening of the electrical cabinet cover plate.
[0020] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 A pair of support frames 5 are provided on the top frame 4. The support frames 5 are gantry structures, including a pair of columns 51 and a horizontal beam 52 connected between the two columns 51. The support frames 5 are provided on the outer side of the guide rail 9, and the axis of the cross beam 52 is perpendicular to the axis of the guide rail 9.
[0021] See also Figure 4 , each support frame 5 is connected to a fixing ring 6, the fixing ring 6 includes a fixing ring 61 connected to the middle of the beam 52, and two L-shaped fixing frames 62 are connected to the two sides of the fixing ring 61, the horizontal end of the fixing frame 62 is connected to the side of the fixing ring 61, and the vertical end is connected to the bottom of the beam 52. A pair of semicircular arc-shaped clamping rings 63 are also provided in the fixing ring 61. The two clamping rings 63 are symmetrically arranged up and down with the center of the fixing ring 61 as the center. The outer side of each clamping ring 63 is connected to the inner side of the fixing ring 61 through a group of springs 64, so as to expand or reduce the ring according to the diameter of the hoisting crossbar;
[0022] See also Figure 2 and Figure 5 A lifting cross bar 7 is connected between the two fixing rings 6, the axis of the lifting cross bar 7 is parallel to the axis of the guide groove 3a, the two ends of the lifting cross bar 7 pass through the fixing rings 6 on both sides, and the lifting cross bar 7 spans over the cover plate 3, and a hand chain hoist 8 that cooperates with each other is connected to the lifting cross bar 7, and the hand chain hoist 8 extends downward into the electrical cabinet body 1 and is connected to the large equipment 2, so as to be used to directly lift the large equipment out of the electrical cabinet;
[0023] See also Figure 4 and Figure 5A gap 65 is provided between the two clamping rings 63, and a pair of limiting columns 71 are fixed at both ends of the lifting cross bar 7. The limiting columns 71 are arranged perpendicular to the lifting cross bar 7. The total length of each pair of limiting columns 71 is smaller than the inner diameter of the fixing ring 61 and larger than the outer diameter of the clamping ring 63. The width of the gap 65 is larger than the diameter of the limiting column 71. When the lifting cross bar 7 extends between the two clamping rings 63, the limiting column 71 passes through the corresponding gap 65 to limit the cross bar when the lifting cross bar is assembled into the fixing ring to prevent it from rolling and sliding during equipment replacement.
[0024] In this embodiment, the lifting crossbar 7 is made of a thick-walled steel pipe with a diameter of 25 mm, and the fixing ring 6 is a steel ring with an inner diameter larger than the outer diameter of the lifting crossbar, such as an inner diameter of 30 mm.
