Description

Technical Field

[0001] The utility model relates to a lifting lug, in particular to an anti-detachment lifting lug for a ring network cabinet. Background Art

[0002] The lifting lug is a load-bearing component installed on the equipment for lifting. The lifting lug is an important connection component in equipment lifting, which is directly related to the safety of large equipment lifting. The lifting lug is often installed in a fixed connection with the hoisted equipment, such as welding, threaded connection, etc. It is inconvenient to frequently disassemble and assemble when the equipment needs to be changed. For example, in the production of ring network cabinets, they are often made into independent units or cabinet units according to needs. When a single independent cabinet needs to be combined, the lifting lug at the middle cover plate needs to be removed when combining cabinets, which is inconvenient to operate and wastes too much time. Summary of the invention

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model aims to provide an anti-detachment lifting lug which is easy to install and disassemble.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A ring network cabinet anti-separation lifting ear, the top of both sides of the ring network cabinet are provided with prefabricated through grooves for lifting by the lifting ear; the lifting ear as a whole is an inverted "T"-shaped structure composed of a lower cross bar and an upper hanging piece; the upper part of the hanging piece is provided with a through hole for lifting, and the two sides of the lower part are provided with grooves, and the grooves are through grooves; the grooves are obliquely cut into the hanging piece from top to bottom, and are bent outward at the bottom of the groove to form an arc-shaped groove surface; the two grooves on both sides separate the two sides of the hanging piece into two reserved ribs; the reserved ribs are bent toward the front or rear side of the hanging piece after the lifting ear is installed, and the bent reserved ribs form a limiting angle with the hanging piece; the lifting ear is clamped on the prefabricated through groove through the lower cross bar and the reserved ribs.

[0006] Preferably, the prefabricated through grooves are arranged on both sides of the top plate or on the top of the side plate of the ring network cabinet.

[0007] Preferably, the grooving is performed by laser grooving.

[0008] The lifting lug disclosed in the utility model has a simple structure and is "T" shaped as a whole. The force support for installation and lifting is achieved through the horizontal bar at the bottom. When installing, the lifting lug is inserted from the lower side of the prefabricated through groove, and the reserved ribs are manually bent. When removing, the operation is reversed. The overall installation and disassembly is extremely convenient. It is especially used in the ring network cabinet, which makes the cabinet assembly and transportation convenient and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 This is a schematic diagram of the overall structure after installation;

[0010] Figure 2 This is the structural diagram of the lifting lug;

[0011] Figure 3 This is a side view of the lifting lug structure.

[0012] In the figure: 1, lifting ear; 11, cross bar; 12, hanging piece; 13, through hole; 14, slot; 15, reserved rib; 100, ring network cabinet. Implementation

[0013] The structure and principle of the present utility model are now fully described in conjunction with specific embodiments so that those skilled in the art can fully understand and implement them.

[0014] like Figures 1 to 3 As shown, a ring main unit anti-detachment lifting ear is provided, and prefabricated through grooves for lifting the lifting ears 1 are provided on the tops of both sides of the ring main unit 100; as shown in the figure, the prefabricated through grooves are designed on the tops of the two side plates.

[0015] The lifting ear 1 as a whole is an inverted "T"-shaped structure consisting of a lower cross bar 11 and an upper hanging piece 12; the upper part of the hanging piece 12 is provided with a through hole 13 for lifting, and the lower two sides are provided with grooves 14, and the grooves 14 are through grooves; the grooves 14 cut into the hanging piece 12 obliquely from top to bottom, and bend outward at the bottom of the groove to form an arc-shaped groove surface; the two grooves 14 on both sides separate the two sides of the hanging piece 12 into two reserved ribs 15; the reserved ribs 15 are bent toward the front or rear side of the hanging piece 12 after the lifting ear 1 is installed, and are shown in the figure as bending outward from the center of the ring network cabinet 100, and the bent reserved ribs 15 form a limiting angle α with the hanging piece 12; the lifting ear 1 is clamped on the prefabricated through groove through the lower cross bar 11 and the reserved ribs 15.

[0016] Wherein: the groove 14 is cut by laser.

[0017] When in use, the reserved ribs 15 of the lifting ear 1 are not bent. The lifting ear 1 is inserted from the bottom of the prefabricated through slot and clamped by the cross bar 11 to form a force-bearing surface. At this time, it can be hoisted or the reserved ribs 15 can be bent before hoisting. When the hoisting is completed or in an idle state, the lifting ear 1 sags under the action of gravity, and the bent reserved ribs 15 are clamped on the top of the ring network cabinet 100. The bending of the reserved ribs 15 can be completed manually, so the disassembly and assembly of the lifting ear 1 is extremely convenient. The reserved ribs 15 are only used to bear the weight of the lifting ear 1 itself when idle, so the force is very small, and even if it is bent frequently, it will not cause failure, and the service life is long.

[0018] The above embodiments are only preferred embodiments of the present invention, and are not any formal limitations on the present invention. Any technician familiar with the art can use the above disclosed method to make many possible changes and modifications to the technical solution of the present invention without departing from the technical principle and solution scope of the present invention, or modify it into an equivalent embodiment with equivalent changes. Therefore, any combination, modification or replacement of the technical features disclosed in the present invention based on the technical essence of the present invention without departing from the principle or solution of the present invention shall fall within the protection scope of the technical solution of the present invention.
