Description

Technical Field

[0001] This utility model relates to the field of ring network box technology, specifically a ring network box. Background Technology

[0002] A ring main unit is a high-voltage switchgear used in ring distribution networks. It is mainly used to connect ring network lines and improve the power supply reliability of the lines. It integrates a certain number of ring main units into a metal box to form a complete power distribution equipment.

[0003] Due to their large weight, existing ring main units require hoisting when moved. In conventional operations, the hoisting ropes are attached to the four hoisting connecting shafts at the bottom of the unit. However, since the top of the ring main unit has a cover protruding from the unit, the hoisting ropes are prone to contacting the cover during hoisting. When the hoisting ropes are under tension, they will exert pressure on the cover, which may lead to damage to the cover. Utility Model Content

[0004] The purpose of this utility model is to provide a ring network box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ring mesh box, comprising a box body, a top cover installed on the top of the box body, and a door hinged to the box body. A hoisting connecting shaft is symmetrically fixedly connected to the bottom of both the front and rear sides of the box body. A baffle is provided at the end of the hoisting connecting shaft away from the box body. Multiple L-shaped rods are provided on the outer side of the hoisting connecting shaft. One end of each L-shaped rod is connected to the baffle. A limiting groove is formed between the L-shaped rod and the hoisting connecting shaft. Multiple support columns corresponding to the hoisting connecting shaft are fixedly connected to the outer side of the box body. One end of each support column is provided with a second threaded hole, and a connecting rod is threaded into the interior of the second threaded hole. One end of each connecting rod is provided with a hook ring.

[0006] As a preferred embodiment of this utility model, the support column is provided with a first threaded hole, and the first threaded hole is connected to a second threaded hole.

[0007] As a preferred embodiment of this utility model, a second limiting plate is provided at the end of the hoisting connecting shaft away from the baffle, one side of the second limiting plate abuts against the inner side wall of the box body, and a first limiting plate is provided in the middle of the hoisting connecting shaft, one side of the first limiting plate abuts against the outer side wall of the box body.

[0008] In a preferred embodiment of this utility model, the support column and the adjacent hoisting connection shaft are on the same straight line.

[0009] As a preferred embodiment of this utility model, the outer side of the box door is provided with louvered holes.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the hook and ring set by this utility model can not only effectively limit the lifting rope to prevent it from deviating and causing the box to tilt or even overturn, but also prevent the lifting rope from directly contacting the top cover, avoiding damage to the top cover when the lifting rope is taut, thereby ensuring the stability and reliability of the lifting operation.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 6This utility model provides a technical solution: a ring mesh box, including a box body 1, a top cover 2 installed on the top of the box body 1, and a box door 3 hinged to the box body 1. A hoisting connecting shaft 10 is symmetrically fixedly connected to the bottom of both the front and rear sides of the box body 1. A baffle 12 is provided at the end of the hoisting connecting shaft 10 away from the box body 1. Multiple L-shaped rods 14 are provided on the outer side of the hoisting connecting shaft 10. One end of each L-shaped rod 14 is connected to the baffle 12. A limiting groove 13 is formed between the L-shaped rod 14 and the hoisting connecting shaft 10. The limiting groove 13 formed by the L-shaped rod 14 and the hoisting connecting shaft 10 is used to limit the hoisting rope and prevent it from... Before and during hoisting, the hoisting rope may detach from the hoisting connecting shaft 10. Multiple support columns 5 corresponding to the hoisting connecting shaft 10 are fixedly connected to the outside of the box body 1. One end of the support column 5 is provided with a second threaded hole 7. The internal thread of the second threaded hole 7 is connected to a connecting rod 8. One end of the connecting rod 8 is provided with a hook ring 9. During hoisting, the hook ring 9 can not only limit the hoisting rope to prevent it from shifting and causing the box body 1 to tilt or even overturn, but also prevent the hoisting rope from directly contacting the top cover 2, thus avoiding damage to the top cover 2 when the hoisting rope is taut, thereby ensuring the stability and reliability of the hoisting operation.

[0020] The support column 5 has a first threaded hole 6. After hoisting, the connecting rod 8 can be screwed into the first threaded hole 6 to store the connecting rod 8 and the hook ring 9, preventing them from protruding from the box body 1. The first threaded hole 6 is connected to the second threaded hole 7.

[0021] The hoisting connecting shaft 10 is provided with a second limiting plate 15 at one end away from the baffle 12. One side of the second limiting plate 15 abuts against the inner side wall of the housing 1. The hoisting connecting shaft 10 is provided with a first limiting plate 11 in the middle. The first limiting plate 11 and the second limiting plate 15 are used to limit the hoisting connecting shaft 10 to prevent movement between the hoisting connecting shaft 10 and the housing 1, and to ensure that the hoisting connecting shaft 10 is firmly fixed. One side of the first limiting plate 11 abuts against the outer side wall of the housing 1.

[0022] Among them, the support column 5 and the adjacent hoisting connection shaft 10 are on the same straight line, so that the hoisting rope and the box body 1 remain perpendicular to each other, and the box body 1 is prevented from tilting during hoisting.

[0023] The outer side of the cabinet door 3 is provided with louvered holes 4, which facilitates heat dissipation of the ring network cabinet inside the cabinet 1 and avoids excessive temperature.

[0024] Specifically, during hoisting, the hoisting rope is first passed through multiple limiting grooves 13 in sequence and then tied to the hoisting connecting shaft 10. Then, one end of the hoisting rope is passed through the hook 9, and finally the hoisting rope is hung on the hook of the hoisting equipment. Once all four hoisting ropes are installed, the hoisting operation can be carried out. After the hoisting operation is completed, the connecting rod 8 is unscrewed and screwed into the first threaded hole 6 for fixation to prevent the hook 9 from protruding outside the box 1.
