Technical Field

[0001] The utility model relates to the technical field of power distribution cabinet hoisting, in particular to a hoisting component for a power distribution cabinet. Background Art

[0002] Distribution cabinets are mainly divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final equipment of the power distribution system and are widely used in the field of electrical equipment to provide protection, monitoring, and control for the applied circuit equipment. During the installation and layout of the distribution cabinet, due to its relatively large weight and volume, the distribution cabinet needs to be moved to the designated location by hoisting. In existing technologies, some use ropes to tie the distribution cabinet and then connect it to a crane or other hoisting equipment. The bundling and disassembly process is relatively cumbersome. Others use lifting rings installed on the top of the distribution cabinet and connect it to the hoisting equipment through the lifting rings for hoisting. However, on the one hand, the lifting rings are welded to the distribution cabinet and are not easy to disassemble. On the other hand, when hoisted through the lifting rings, the stability is poor. The weight of the distribution cabinet requires a high strength of the lifting rings, and the lifting rings are prone to breakage. Utility Model Content

[0025] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0026] Example

[0027] As mentioned in the background technology, the existing distribution cabinet needs to be hoisted during installation. The existing hoisting method has many defects. For example, the rope binding method is cumbersome and requires a very firm method to ensure the stability of the hoisting. The lifting ring is not easy to disassemble and has high requirements on the strength of the lifting ring. Therefore, the inventor has made improvements and designed a new type of lifting part, which is described in detail below with reference to the drawings.

[0028] This embodiment provides a hanging fixture for a power distribution cabinet. Figure 1-Figure 3 A hanging part for a distribution cabinet is detachably connected to the upper end of the distribution cabinet body 1, and connection holes 3 are pre-opened at the four corners of the top plate 2 of the distribution cabinet body 1. The connection holes 3 are opened through the top plate 2 and are opened at the position of the existing distribution cabinet installation ring, including two support beams 4 connected to the top of the distribution cabinet. The length of the two support beams 4 is not greater than the length of the top plate 2 of the distribution cabinet. After being installed with the distribution cabinet body 1, they are in conflict with the top plate 2 and are located at the edge of the top plate 2.

[0029] In this embodiment, at least two connecting beams 5 are arranged between the two supporting beams 4. Figure 3In this solution, two connecting beams 5 are provided and are arranged symmetrically with respect to the center line of the supporting beam 4. In order to facilitate the fixation of the supporting beam 4 and the distribution cabinet and to facilitate lifting, the upper end surfaces of both ends of the two supporting beams 4 are penetrated with sockets 6, and a lifting ring assembly 7 is inserted into the socket 6. The bottom of the lifting ring assembly 7 passes through the connecting hole 3 and is connected to the top plate 2. Specifically, the lifting ring assembly 7 includes a lifting ring body 71, which is located at the upper end of the supporting beam 4, and a stud 72 is connected to the bottom of the lifting ring body 71, and the stud 72 passes through the bottom of the top plate 2 and is fixed by a threaded barrel 73, that is, the threaded barrel 73 is connected to the bottom end of the stud 72, and is rotated upward until it is against the top plate 2 to fix the stud 72, thereby realizing the fixation of the lifting ring body 71, and finally fixing the supporting beam 4 above the top plate 2.

[0030] It should be noted that due to the different sizes of distribution cabinets, the distances between the connection holes 3 opened on the top plate 2 are also different. Therefore, in order to make this lifting component adaptable to the use of distribution cabinets of more different sizes, the sockets 6 are provided in multiple directions along the length direction of the support beam 4, that is, there are multiple sockets 6 at both ends of the support beam 4. When used for distribution cabinets of different sizes, when the center line of the support beam 4 is aligned with the center line of the distribution cabinet, the socket 6 aligned with the connection hole 3 can be selected to install the lifting ring assembly 7.

[0031] On the basis of the above structure, the connecting beam 5 is connected to a connecting plate 8 extending toward the outside of the distribution cabinet body 1. The connecting plate 8 extends outward beyond the distribution cabinet, and the connecting plate 8 is located in the middle position of the two support beams 4, which can ensure the overall balance. The connecting plate 8 is connected to the limit plate 10 through the connecting member 9, and the limit plate 10 is arranged vertically downward and can be moved to offset the side of the distribution cabinet body 1, that is, the limit plate 10 can move and be fixed along the length direction of the connecting plate 8, and can adapt to the use of distribution cabinets of different widths.

[0032] Specifically, the connecting plate 8 is provided with a sliding groove 11 along its length direction. Figure 2 The slide groove 11 is located in the middle position of the connecting plate 8, and the connecting member 9 includes a threaded rod 91 fixed to the top of the limit plate 10, and the threaded rod 91 passes through the slide groove 11 and is threadedly connected to a butterfly nut 92, that is, the threaded rod 91 passes through the slide groove 11 and extends to the upper end of the connecting plate 8, and the butterfly nut 92 is located above the connecting plate 8. Moreover, in order to ensure the stability of the connection of the threaded rod 91 and facilitate the movement of the threaded rod 91 along with the limit plate 10, an inverted U-shaped slide plate 93 is provided between the butterfly nut 92 and the connecting plate 8, and the threaded rod 91 passes through the slide plate 93. The opening of the slide plate 93 faces the connecting plate 8 and is buckled on its upper end and can slide along its length.

[0033] It should be noted that the bottom end of the threaded rod 91 is connected to an inverted U-shaped mounting bracket 94, and a mounting plate 95 is provided at the top of the limit plate 10. The mounting bracket 94 is snapped onto the mounting plate 95 and fixed by bolts. The threaded rod 91 and the limit plate 10 are fixed by the cooperation of the mounting bracket 94 and the mounting plate 95, which is convenient and quick.

[0034] Moreover, in order to support the bottom of the distribution cabinet body 1, Figure 4 The limiting plate 10 is provided with a receiving groove 12 in the vertical direction, and a supporting plate 13 is placed in the receiving groove 12 of the two limiting plates 10. The supporting plate 13 can move up and down in the receiving groove 12. A plurality of mounting holes 14 are provided on both sides of the receiving groove 12 from top to bottom, and supporting columns 15 are installed in the two opposite mounting holes 14 to support the supporting plate 13. The supporting columns 15 are selected according to the height of the distribution cabinet body 1 to match the mounting holes 14 at the corresponding height, and the supporting plate 13 is supported at the height of the bottom end surface of the distribution cabinet body 1.
