A hoist and tank assembly and gas-filled tank

Abstract

This application relates to a hoisting and merging unit and an inflatable cabinet, including a merging component. The merging component has a first hoisting hole, a first clearance opening, a second hoisting hole, and a second clearance opening arranged sequentially at intervals along a horizontal direction. The distance between the first hoisting hole and the second hoisting hole is equal to the distance between the first clearance opening and the second clearance opening. By adding clearance openings corresponding to the hoisting holes, the existence of the clearance openings has two advantages: firstly, during the hoisting and merging process, when the hook enters the clearance opening during lowering, it is considered that the position adjustment between the two inflatable cabinets is completed, which facilitates the operation of workers; secondly, the hook can be accommodated in the clearance opening during the hoisting and merging process and will not be blocked by the merging component. The hoisting and merging can be completed in one complete lifting and lowering operation, which is simple and convenient, shortens the hoisting and merging time, improves the hoisting and merging efficiency, and also helps to reduce collisions between the two inflatable cabinets and reduce safety hazards during the hoisting and merging process.

Description

Technical Field

[0001] This utility model relates to the technical field of hoisting and cabinet merging devices, and in particular to a hoisting and cabinet merging assembly and an inflatable cabinet. Background Technology

[0002] With the development of the power industry, the application of gas-insulated switchgear (GES) is becoming increasingly widespread. Because the structural requirements for GES are more stringent than those for air-insulated switchgear, especially considering that a single GES unit can weigh up to 1 ton, and installation and paralleling are more complex, it is difficult to move a GES unit once it is placed on the foundation. Therefore, direct hoisting and paralleling is the most convenient and quickest method. Thus, the hoisting and paralleling scheme for GES is particularly important. Existing hoisting and paralleling schemes utilize the hoisting holes on the GES unit, typically a pair of lifting lugs welded to the top of the GES unit, with the hoisting holes on the two lugs arranged correspondingly. When two gas-insulated cabinets are far apart, the actual hoisting and merging process requires two lifting and lowering operations. The first lifting and lowering is to adjust the position of one of the gas-insulated cabinets so that the two hoisting holes align. During the second lifting and lowering, the hook is passed through the two hoisting holes to hoist and merge the cabinets. This is not only cumbersome, but also, because the hook has a certain width, it is impossible to completely fit the two gas-insulated cabinets together during the merging adjustment step. A gap still needs to be left for the hook to be removed. If the gap is too large, the hook may not be able to pass through the two hoisting holes at the same time. Using a small hook for adjustment and a large hook for merging undoubtedly increases the cost of hoisting and merging the cabinets. Relying on manual secondary operation for adjustment also poses certain safety hazards. Utility Model Content

[0008] In one embodiment, the cabinet assembly further includes a first bolt hole and a second bolt hole located between the first lifting hole and the second clearance opening, wherein the distance between the first bolt hole and the lifting hole is equal to the distance between the second bolt hole and the second clearance opening; and / or

[0009] The cabinet assembly also has a third bolt hole and a fourth bolt hole located outside the first lifting hole and the second clearance opening, wherein the distance between the third bolt hole and the first lifting hole is equal to the distance between the fourth bolt hole and the second clearance opening.

[0010] In one embodiment, the cabinet component further has a fifth bolt hole, the distance between the fifth bolt hole and the first hoisting hole being equal to the distance between the fifth bolt hole and the second clearance opening.

[0011] In one embodiment, the cabinet assembly has an abutment surface and a mounting surface perpendicular to the abutment surface, the abutment surface being used to abut the abutment surface of another cabinet assembly, and the first lifting hole, the first clearance opening, the second lifting hole and the second clearance opening are all located on the abutment surface.

[0012] In one embodiment, the cabinet assembly includes a mounting plate providing the mounting surface and an abutment plate extending perpendicularly from the edge of the mounting plate and providing the abutment surface.

[0013] In one embodiment, the mounting plate has a plurality of assembly holes, and the hoisting and cabinet assembly further includes a lifting lug inserted into the assembly holes and fixedly connected to the mounting plate and the abutment plate.

[0018] In summary, the hoisting and merging unit provided in this application adds a clearance opening corresponding to the hoisting hole. Due to the existence of the clearance opening, on the one hand, during the hoisting and merging process, after lifting, the hook approaches the clearance opening, and when lowering, the hook enters the clearance opening, which is regarded as the merging of two gas-filled ...

[0037] The existing hoisting and merging scheme relies on the hoisting holes on the original gas-filled cabinets. The merging process requires two hoisting and lowering operations. Since the hooks have a certain width, a gap still needs to be reserved between the two gas-filled cabinets for the hooks to be removed during the actual hoisting and merging process. If the gap is large and the hooks are small, there may be a problem that the hooks cannot pass through the two hoisting holes at the same time during the second hoisting and lowering operation. As a result, the hoisting and merging still requires manual adjustment, which poses certain safety hazards.

[0038] Therefore, it is necessary to provide a hoisting and merging assembly and an inflatable cabinet 30 that are easy to operate and make the hoisting and merging process safer.

[0039] Please see Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 In one embodiment provided in this application, the hoisting and cabinet assembly includes a cabinet assembly 10 and a lifting lug 20; wherein, the cabinet assembly 10 has a first hoisting hole 101, a first clearance opening 102, a second hoisting hole 103, and a second clearance opening 104 arranged sequentially at intervals along the horizontal direction, and the distance d1 between the first hoisting hole 101 and the second hoisting hole 103 is equal to the distance d2 between the first clearance opening 102 and the second clearance opening 104. Figure 7 and Figure 8As shown, the two gas-filled cabinets 30 that need to be combined are respectively equipped with two hoisting and combining assemblies at the edge of the top wall 31. In the hoisting and combining assembly on the left, the holes on the combining component 10 are arranged in the order of second clearance opening 104, second hoisting hole 103, first clearance opening 102, and first hoisting hole 101. In the hoisting and combining assembly on the right, the holes on the combining component 10 are arranged in the order of first hoisting hole 101, first clearance opening 102, second hoisting hole 103, and second clearance opening 104. The actual hoisting and combining process is as follows: the gas-filled cabinet 30 on the left has been lowered, and at this time the hook on the left combining component 10 does not need to be removed, that is, the hook can still be... Using the second lifting hole 103 on the left-side cabinet assembly 10, the right-side gas cabinet 30 moves closer to the left-side gas cabinet 30 before being lowered. At this time, the hook is still inserted through the first lifting hole 101 on the right-side cabinet assembly 10. During cabinet assembly, the second clearance opening 104 on the left-side cabinet assembly 10 makes way for the hook on the right-side cabinet assembly 10, and the first clearance opening 102 on the right-side cabinet assembly 10 makes way for the hook on the left-side cabinet assembly 10. When the hooks on both sides are located in the corresponding clearance openings, the cabinet assembly is considered complete. This facilitates worker operation. The entire cabinet assembly process only requires one lifting and lowering operation, which is highly efficient and also helps to reduce the safety hazards caused by frequent lifting.

[0040] Please see Figure 3 Optionally, the first clearance opening 102 is an arc-shaped groove that matches the shape of the second lifting hole 103, and the second clearance opening 104 is an arc-shaped groove that matches the shape of the first lifting hole 101. This arrangement is intended to facilitate the entry of the hook into the first clearance opening 102 and the second clearance opening 104. On the other hand, both cabinet components 10 can limit the hook after being combined, ensuring accuracy during the lowering process. Furthermore, the outlet of the first clearance opening 102 or the second clearance opening 104 is an outwardly flared opening, which facilitates guiding the hook into the clearance opening during lowering.

[0041] like Figure 3 As shown, furthermore, in order to facilitate the machining of holes on the cabinet component 10, the center of the first lifting hole 101, the center of the first clearance opening 102, the center of the second lifting hole 103, and the center of the second clearance opening 104 are arranged coaxially.

[0042] like Figure 3As shown, to facilitate the connection of two gas-filled cabinets 30 after merging, the merging component 10 is provided with various bolt holes. The merging component 10 also has a first bolt hole 105 and a second bolt hole 106 located between the first lifting hole 101 and the second clearance opening 104. The distance d3 between the first bolt hole 105 and the first lifting hole 101 is equal to the distance d4 between the second bolt hole 106 and the second clearance opening 104. The merging component 10 also has a third bolt hole 107 and a fourth bolt hole 108 located outside the first lifting hole 101 and the second clearance opening 104. The distance d5 between the third bolt hole 107 and the first lifting hole 101 is equal to the distance d6 between the fourth bolt hole 108 and the second clearance opening 104. The merging component 10 also has a fifth bolt hole 109. The distance d7 between the fifth bolt hole 109 and the first lifting hole 101 is equal to the distance d8 between the third bolt hole 107 and the second clearance opening 104.

[0043] like Figure 1 and Figure 2 As shown, the cabinet component 10 has an abutment surface 121 and a mounting surface perpendicular to the abutment surface 121 (not visible from the viewpoint shown). The abutment surface 121 is used to abut against the abutment surface 121 of another cabinet component 10. The first lifting hole 101, the first clearance opening 102, the second lifting hole 103, and the second clearance opening 104 are all located on the abutment surface 121. The mounting surface facilitates the determination of the installation position of the cabinet component 10, ensuring assembly accuracy and simplifying assembly difficulty.

[0044] like Figure 1 and Figure 2 As shown, the cabinet assembly 10 includes a mounting plate 11 providing a mounting surface and an abutment plate 12 extending perpendicularly from the edge of the mounting plate 11 and providing an abutment surface 121. Specifically, the cabinet assembly 10 is made of angle steel, which further reduces processing costs.

[0045] like Figure 1 and Figure 4As shown, to increase the structural strength of the cabinet assembly 10, the mounting plate 11 has multiple assembly holes 112. The cabinet assembly also includes lifting lugs 20 that are inserted into the assembly holes 112 and fixedly connected to the mounting plate 11 and the abutment plate 12. The lifting lugs 20 have third lifting holes 201 that correspond to and communicate with the first lifting hole 101 and / or the second lifting hole 103. The lifting lugs 20 can be regarded as reinforcing ribs of the cabinet assembly. Specifically, the lifting lugs 20 include two parts: a connector 21 and an extension head 22. The connector 21 has a first contact surface 211 that fits against the mounting plate 11 and a second contact surface 212 that fits against the abutment plate 12. The extension head 22 has a third contact surface 221 for fitting against the side wall 32 of the cabinet. In order to accommodate the perpendicular arrangement of the mounting plate 11 and the abutment plate 12 in the cabinet component 10, the side of the connector 21 in the lifting lug 20 is triangular, so that the connector 21 can be accommodated in the groove formed by the perpendicular arrangement of the mounting plate 11 and the abutment plate 12.

[0046] like Figure 8 As shown, furthermore, in order to avoid the extension head 22 of the lifting lug 20 interfering with the merging of the two cabinets, the two side walls 32 of the cabinet are also provided with clearance grooves 301. When the cabinets are merged, the two clearance grooves 301 are connected to each other. It can be understood that the length of the clearance groove 301 extending vertically can be the same as the vertical extension length of the extension head 22, or it can be the same as the vertical height of the side wall 32 of the cabinet.

[0047] like Figure 5 and Figure 6 As shown, in one embodiment provided in this application, the gas-insulating cabinet 30 includes a cabinet body and two hoisting and merging assemblies. The two hoisting and merging assemblies are respectively fixed to both sides of the top wall 31 of the cabinet body, and the abutment surfaces 121 of the two hoisting and merging assemblies are arranged facing away from each other. Referring to the hoisting and merging process described above, this is to make way for the two hooks connecting different gas-insulating cabinets 30. It can be understood that if only one crane is used, that is, only to make way for the hook on the gas-insulating cabinet 30 to be hoisted later, the two hoisting and merging assemblies can also be fixedly connected to the cabinet body with the abutment surfaces 121 arranged in the same direction.

[0048] Optionally, in one embodiment provided in this application, the above-mentioned cabinet assembly 10, lifting lug 20, and cabinet body are connected by welding to facilitate manufacturing. It is understood that in other embodiments, if it is not necessary to rely on the lifting cabinet assembly to connect the two cabinet bodies, the lifting cabinet assembly and the cabinet body can also be connected by a detachable method, such as snap-fit, fastening, locking, etc.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
