[0039] The frame beam 1 is installed at the top and bottom of the switchgear body and forms the frame of the switchgear body. The frame beam 1 has a cavity 11 inside, which is used to install the lifting assembly 3. When not in use, the lifting assembly 3 can be hidden inside the frame beam 1 to avoid affecting the external structure and internal wiring of the switchgear.

[0040] The frame vertical beams 2 are connected with the frame horizontal beams 1 by bolts or other suitable connecting means, and together form the frame of the low-voltage switch cabinet. The frame vertical beams 2 ensure the overall structural stability of the switch cabinet.

[0041] The lifting assembly 3 includes a lifting ring 31 and a base 32, and is arranged in the accommodating cavity 11 of the frame horizontal beam 1. The lifting ring 31 is used to cooperate with a lifting machine (not shown in the figure) to move the low-voltage switch cabinet to a target position.

[0042] The frame horizontal beam 1 is provided with a through hole 12, which is matched in shape and size with the lifting ring 31, so that the lifting ring 31 can be arranged above the frame horizontal beam 1 by passing through the through hole 12. When the lifting assembly 3 needs to be used, the lifting ring 31 extends out of the frame horizontal beam 1 through the through hole 12 and is connected with the lifting machine; when the lifting assembly 3 does not need to be used, the lifting ring 31 can be retracted into the accommodating cavity 11.

[0043] The specific structure of the lifting ring 31 is shown in Figure 4 and Figure 6 , which includes a ring body 311, a seat body 312 and a connecting rod 313.

[0045] In order to facilitate the injection of liquid solder into the recess 321, the side of the base 32 is provided with a filling hole 323. The filling hole 323 is arranged in communication with the recess 321, and the filling hole 323 is at the same horizontal position as the seat body 312. During the welding process, the liquid solder can be injected into the recess 321 through the filling hole 323 and flow around the seat body 312 and the connecting rod 313, and finally solidify to form the filler welding layer 322.

[0046] The materials of the seat body 312 and the ring body 311 are the same as those of the frame horizontal beam 1 and the frame vertical beam 2, which are usually high-quality steel materials, so as to ensure the overall strength and durability of the switch cabinet.

[0047] In use, the lifting hook of the lifting machine is connected with the ring body 311 of the lifting ring 31, and the low-voltage switch cabinet is moved to the target position through the lifting action of the lifting machine. When the lifting assembly 3 is not needed to be used, the lifting ring 31 can be withdrawn into the accommodating cavity 11, so as to avoid affecting the external structure and internal wiring of the switch cabinet.

[0048] The low-voltage switch cabinet provided by the application realizes the stability of the switch cabinet and the purpose of facilitating carrying and installation by reasonably designing the structures of the frame cross beam 1, the frame vertical beam 2 and the lifting assembly 3. In particular, the design of the lifting assembly 3 enables the lifting ring 31 to be hidden in the frame cross beam 1 when not in use, thereby avoiding affecting the external structure and internal wiring of the switch cabinet and improving the practicability and aesthetic appearance of the switch cabinet.

The frame cross beam 1 is internally designed with an accommodating cavity 11, which is used to install the lifting assembly 3, so that the lifting assembly 3 can be hidden in the frame cross beam 1 when not in use, thereby avoiding affecting the external structure and internal wiring of the switch cabinet. The frame cross beam 1 is further provided with a through hole 12, which is matched in shape and size with the lifting ring 31, so as to facilitate the lifting ring 31 to pass through the through hole 12 and be arranged above the frame cross beam 1.

[0052] The frame vertical beam 2 is connected with the frame cross beam 1 through bolt connection or other suitable connection modes, and together forms the frame of the low-voltage switch cabinet. The arrangement of the frame vertical beam 2 ensures the overall structural stability of the switch cabinet.

[0053] The lifting assembly 3 comprises a lifting ring 31 and a base 32 and is arranged in the accommodating cavity 11 of the frame cross beam 1. The lifting ring 31 is used to cooperate with a lifting machine (not shown in the figure) to move the low-voltage switch cabinet to a target position.

The first groove body 3211 is used to accommodate the connecting rod 313, and the second groove body 3212 is used to accommodate the seat body 312. This design can ensure that the connecting rod 313 and the seat body 312 can be firmly installed on the base 32, and is convenient for installation and disassembly.

[0056] The bottom of the seat body 312 is also provided with a convex ring 3121, the shape of the second groove body 3212 is the same as that of the seat body 312, and the bottom of the second groove body 3212 is provided with an annular groove matched with the convex ring 3121, which can further increase the connection strength between the seat body 312 and the base 32, and prevent the seat body 312 from loosening or falling off during use.

[0057] The materials of the seat body 312 and the ring body 311 are the same as those of the frame cross beam 1 and the frame vertical beam 2, which are usually high-quality steel materials, so as to ensure the overall strength and durability of the switch cabinet.

[0058] In use, the lifting hook of the lifting machine is connected with the ring body 311 of the lifting ring 31, and the low-voltage switch cabinet is moved to the target position through the lifting action of the lifting machine. When the lifting assembly 3 is not needed, the lifting ring 31 can be withdrawn into the accommodating cavity 11, so as to avoid affecting the external structure and internal wiring of the switch cabinet. Since the lifting ring 31 is rotatably arranged on the top of the base 32, the lifting ring 31 can rotate with the lifting hook of the lifting machine during lifting, thereby avoiding scratching or damaging the external structure of the switch cabinet.

[0059] The low-voltage switch cabinet provided by the application realizes the stability of the switch cabinet and the purpose of facilitating transportation and installation by reasonably designing the structures of the frame cross beam 1, the frame vertical beam 2 and the lifting assembly 3. In particular, the design of the lifting assembly 3 enables the lifting ring 31 to be hidden inside the frame cross beam 1 when not in use, thereby avoiding affecting the external structure and internal wiring of the switch cabinet. Meanwhile, the lifting ring 31 is rotatably arranged on the top of the base 32, thereby avoiding scratching or damaging the external structure of the switch cabinet during lifting, and improving the practicability and aesthetics of the switch cabinet.
