Description

Technical Field

[0001] This utility model relates to a lifting beam with a special hook for transformer ring main units and a weighing function, belonging to the technical field of transformer ring main units. Background Technology

[0002] In the construction of high-voltage power grids, the hoisting of transformer ring main units is frequently involved. These ring main units house transformers and resemble small shipping containers, with four lifting lugs extending from the bottom. The lugs have a small diameter, the outer baffles are also small, and the ground clearance is low, making it difficult to find suitable hoisting tools. Therefore, we designed a lifting beam with a dedicated hook and weighing function for transformer ring main units. Firstly, the hook is specifically designed for transformer ring main units, allowing for safe and reliable attachment to the lugs. Secondly, the slings integrate a tension sensor to detect the weight of the ring main unit, making the hoisting operation more scientific and efficient.

[0003] To address this, a lifting beam with a dedicated hook for transformer ring main units and a weighing function is proposed. Utility Model Content

[0004] In view of this, the present invention provides a lifting beam with a special hook for transformer ring main units and a weighing function to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0005] The technical solution of this utility model is implemented as follows: a lifting beam with a special hook for transformer ring network boxes and a weighing function, including a lifting beam, a lifting beam mechanism at the bottom of the lifting beam, the lifting beam mechanism including a sling, a weighing sensor and a connecting ring, the sling being movably connected to the surface of the lifting beam, the top of the weighing sensor being movably connected to the bottom of the sling, and the top of the connecting ring being movably connected to the bottom of the weighing sensor.

[0006] More preferably, the lifting beam is provided with fixed hooks on both the front and rear sides, and the fixed hooks are movably connected to movable rods.

[0007] More preferably, a lifting lug is fixedly connected to the top of the lifting beam, and a connecting column is movably connected inside the lifting lug.

[0008] More preferably, a flexible sling is movably connected to the bottom of the connecting ring, and a hook is movably connected to the bottom of the flexible sling.

[0009] More preferably, the hook is internally movably connected to a clamping plate, and a through flexible sling of the clamping plate extends into the interior of the hook.

[0010] More preferably, the outer side of the hook is movably connected to a bolt, and the inner side of the bolt extends into the interior of the clamping plate.

[0011] More preferably, a safety lock is movably connected to the bottom of the hook, and the surface of the safety lock is in contact with the surface of the hook.

[0012] The present invention has the following advantages due to the adoption of the above technical solution:

[0013] I. This utility model uses a lifting beam mechanism, with lifting lugs installed on the upper part of the lifting beam for connection with a crane. Four sets of lifting slings are installed below the lifting beam, with a weighing sensor installed below each set of lifting slings. A flexible sling is installed below each weighing sensor. Since the outer shell of the transformer ring main unit is thin, steel wire ropes or chains are easily damaged. Therefore, flexible slings are used to protect the outer shell of the transformer ring main unit.

[0014] II. This utility model uses a hook designed according to the shape of the lifting lug on the outside of the ring mesh box. The size of the hook cavity matches the lifting lug of the ring mesh box, and the hook shape is relatively slender, which can be well applied to occasions with small ground clearance. The hook cavity is deep, which ensures that the lifting lug has a certain stroke in the hook cavity when the ring mesh box is subjected to vibration, making it less likely to fall off the hook.

[0015] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0021] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] Example 1

[0024] like Figure 1-2 As shown, this utility model embodiment provides a lifting beam with a special hook for transformer ring main units and a weighing function, including a lifting beam 1. A lifting beam mechanism 2 is provided at the bottom of the lifting beam 1. The lifting beam mechanism 2 includes a sling 201, a weighing sensor 202, and a connecting ring 203. The sling 201 is movably connected to the surface of the lifting beam 1. The top of the weighing sensor 202 is movably connected to the bottom of the sling 201. The top of the connecting ring 203 is movably connected to the bottom of the weighing sensor 202. Fixed hooks 3 are provided on the front and rear sides of the lifting beam 1. Movable rods 4 are movably connected to the surface of the fixed hooks 3. Lifting lugs 5 are fixedly connected to the top of the lifting beam 1. Connecting columns 6 are movably connected inside the lifting lugs 5.

[0025] The lifting lug 5 is installed on the upper part of the lifting beam 1 via the lifting beam mechanism 2 for connection with the crane. Four sets of lifting slings 201 are installed below the lifting beam 1. Each set of lifting slings 201 has a load cell below it. A flexible sling 7 is installed below each load cell. Since the outer shell of the transformer ring main unit is thin, it is easy to damage it with steel wire rope or chain. Therefore, the flexible sling 7 is used to protect the outer shell of the transformer ring main unit.

[0026] Example 2

[0027] like Figure 3 As shown, in one embodiment, a flexible sling 7 is movably connected to the bottom of the connecting ring 203, a hook 8 is movably connected to the bottom of the flexible sling 7, the inside of the hook 8 is movably connected to a clamping plate 9, the clamping plate 9 extends through the flexible sling 7 into the inside of the hook 8, a bolt 10 is movably connected to the outside of the hook 8, the inside of the bolt 10 extends into the inside of the clamping plate 9, and a safety lock 11 is movably connected to the bottom of the hook 8, the surface of the safety lock 11 is in contact with the surface of the hook 8.

[0028] The hook 8 is designed according to the shape of the lifting lug on the outside of the ring network box. Its hook cavity size matches the lifting lug of the ring network box, and the hook shape is relatively slender, which can be well applied to occasions with small ground clearance. The hook cavity is deep to ensure that the lifting lug has a certain stroke in the hook cavity when the ring network box is subjected to vibration, so that it is not easy to disengage.

[0029] In operation, this invention works as follows: First, the crane lifts the entire lifting beam 1 via the connecting lugs 5, moves it above the transformer ring main unit, lowers the lifting beam 1 until the hook 8 is on the ground, and then lays the hook 8 horizontally with the safety lock 11 facing the ground. The hook 8 is inserted from the side of the lug 5 shaft of the transformer ring main unit, allowing the lug 5 shaft to slide along the hook cavity into the bottom of the hook cavity. Once the lugs 5 shafts of all four ring main units are hooked into the corresponding hook cavities of the dedicated hooks 8, the crane is raised, and the ring main units are lifted using the hooks 8. After the transformer ring main units are lifted, they are left to stand for several minutes until they stabilize. At this point, the weight data output by the weighing sensor is the actual weight of the ring main unit.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
