Description

Technical Field

[0001] This utility model relates to a fixing frame, specifically a fixing frame for stacking transformers. Background Technology

[0002] After a transformer is manufactured, it needs to be transported short or long distances before installation and use. During transportation, the transformer is placed in a carriage or container and protected using certain securing methods.

[0003] like Figure 1 The diagram shows the structure of a transformer, which mainly includes a lower main housing 1 and an upper bushing section 2. A housing cover is provided between the main housing 1 and the bushing section 2. A ring of bolts is distributed around the edge of the housing cover to fix the housing cover and the main housing 1. At the bottom of the transformer main housing 1, two parallel bottom rods 4 are welded and fixed to place and support the transformer. The bottom rods 4 are long grooved channel steels. Bolt holes for transformer installation are opened at both ends of the two bottom rods 4. The transformer can be installed and fixed in the specified position by the cooperation of bolts and nuts through the bolt holes.

[0004] Due to the bushing section 2 above the transformer, transformers are generally placed in a single layer, and this is also the case when transporting transformers in a wagon or container. They are then simply secured with wire, straps, or a dedicated transformer securing device. Chinese utility model patent CN 210039829 U discloses a protective device for transformer transportation, including a transport box, a securing mechanism, and a positioning mechanism, which can secure the transformer. However, this transformer securing device has a complex structure, making installation and disassembly time-consuming and labor-intensive. It is also only applicable to a specific type of transformer, limiting its applicability. Furthermore, it occupies a large amount of space. In summary, whether using a simpler method or a dedicated transformer securing device, transformers are always placed in a single layer. When transporting transformers in bulk, and when existing wagons or containers have sufficient height space, the single-layer placement method limits the total number of transformers that the wagon or container can carry, necessitating additional vehicles and significantly increasing transportation costs. Utility Model Content

[0005] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a mounting frame that can be used for stacking transformers, allowing transformers to be stacked vertically inside a vehicle or container, and enabling rapid installation and disassembly, thus solving the problem of high transportation costs when transporting transformers in bulk.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a fixing frame for stacking transformers, including a vertical frame, the vertical frame including a first frame and a second frame, the first frame and the second frame being rectangular frames arranged parallel to each other on both sides of the transformer; a plurality of lower fixing holes for bolting the lower transformer base rod are opened on the lower frame of the vertical frame, and a plurality of upper fixing holes for bolting the upper transformer base rod are opened on the upper frame.

[0007] As a limitation of this utility model: the vertical frame is detachably provided with a fixing rod for connecting and fixing the vertical frame to the transformer box cover below.

[0008] As a limitation of this utility model: the fixing rod is arranged horizontally, and several center fixing holes are opened in the middle of the vertical frame of the vertical frame. A first connecting hole for bolt connection is opened at one end of the fixing rod, which matches the center fixing hole. Several second connecting holes for bolt connection with the transformer box cover below are opened at the other end of the fixing rod.

[0009] As a limitation of this utility model: a horizontally arranged internal connecting rod is detachably connected between the two vertical frames on the same side of the first frame and the second frame, and several third connecting holes are respectively opened at both ends of the internal connecting rod so as to be connected to the central fixing hole bolt.

[0010] As a limitation of this utility model: a horizontally arranged external connecting rod is detachably connected between the fixing frame and another adjacent fixing frame, and several fourth connecting holes are respectively opened at both ends of the external connecting rod so as to be connected to the central fixing hole bolt.

[0011] As a limitation of this utility model: the third connecting hole and the fourth connecting hole are oblong holes.

[0012] As a limitation of this utility model: the vertical frame is welded from channel steel, and the fixing rod, internal connecting rod, and external connecting rod are made of channel steel.

[0013] As a limitation of this utility model: a support part is fixedly provided at the lower end of the vertical frame, and the support part is composed of support rods arranged horizontally.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0015] (1) This utility model utilizes the structural characteristics of the transformer itself. The original openings on the bottom rod of the transformer and the bolt holes on the edge of the middle tank cover are fixed to the lower fixing holes and the middle fixing holes provided by this device with bolts and nuts, thereby fixing the lower transformer. After the lower transformer is fixed, the upper transformer is placed on the fixing frame, and the openings on the bottom rod of the upper transformer are fixed to the upper fixing holes with bolts and nuts, thereby fixing the upper transformer. This fixing structure is simple in construction, the bolt and nut fixing method is convenient, and the overall frame has low manufacturing cost. It can meet the requirements for fixing the transformer during transportation, and at the same time realizes the purpose of stacking two transformers, making full use of the height space of the carriage or container, doubling the transportation quantity, and greatly reducing transportation costs.

[0016] (2) The lower fixing hole, upper fixing hole, middle fixing hole, first connecting hole, second connecting hole, third connecting hole, and fourth connecting hole of this utility model can be set in multiple ways, and can be set to different hole spacings as needed to meet the fixing requirements of transformers of different sizes; the third connecting hole and the fourth connecting hole are set to the shape of an elongated oval hole, so that the position of the bolt can be finely adjusted to improve the fixing accuracy.

[0017] (3) After the first frame, the second frame and the fixing rod of this utility model are fixed, they are almost attached to the transformer, without occupying extra space, which further improves the space utilization rate. Moreover, after transportation, the first frame and the second frame can be quickly disassembled. The first frame and the second frame are split structures, which makes the overall volume of the disassembled fixing frame small, which is convenient for handling, storage and transportation.

[0018] (4) The present invention strengthens the fixing effect between the first frame and the second frame by internal connecting rods; the fixing frame is connected and fixed with the adjacent fixed frame by external connecting rods, so that the fixed frame forms an integral structure, further enhancing the stability effect; and the frame structure also facilitates the secondary fixing of the fixed frame by fixing straps (pulling straps), so that the fixed frame is fixed to the carriage or container as one unit.

[0019] In summary, this utility model has a simple structure and low manufacturing cost. It can realize the stacking of transformers, fix different types of transformers, and can be quickly fixed and disassembled. It is suitable for bulk transportation of transformers in carriages or containers, which improves the space utilization of carriages or containers and significantly reduces transportation costs.

Detailed Implementation

[0025] The preferred embodiments of this utility model are described below with reference to the accompanying drawings. It should be understood that the fixing frame for stacking transformers described herein is a preferred embodiment and is only used for illustration and explanation of this utility model, and does not constitute a limitation thereof.

[0026] The directional terms or positional relationships used in this utility model, such as "up," "down," "left," and "right," are based on the positional relationships in the accompanying drawings of this utility model. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model. Example

[0027] This implementation example Figure 2 , Figure 3 The image shows a mounting frame for stacking transformers, comprising a vertical frame, which includes a first frame 5 and a second frame 6. The first frame 5 and the second frame 6 are independent rectangular frames, arranged parallel to each other on both sides of the transformer. The transformers that can be stacked on this mounting frame are a lower transformer 7 (located at the bottom) and an upper transformer 8 (located at the top).

[0028] like Figure 2As shown, the first frame 5 and the second frame 6 each include an upper frame, a lower frame, and two vertical frames. Several lower fixing holes 9 are formed along the length of the lower frame. These holes 9 are matched with bolt holes on the bottom rod 4 of the lower transformer 7, facilitating the bolting of the lower transformer 7 to the vertical frame using bolts and nuts (the bolt and nut structures are omitted in the figure to show the holes). Several upper fixing holes 10 are formed along the length of the upper frame. These holes 10 are matched with bolt holes on the bottom rod 4 of the upper transformer 8, facilitating the bolting of the upper transformer 8 to the vertical frame using bolts and nuts. In addition, detachable fixing rods 11 are provided on the vertical frame of the vertical frame. The fixing rods 11 are used to connect and fix the vertical frame to the transformer 7 tank cover 3 below. Specifically, the fixing rod 11 is a long channel steel that is horizontally arranged and has its opening facing one side. Several center fixing holes 12 are opened along its length on the vertical frame. A first connecting hole 14 for bolt connection is opened on the wall along the height direction at one end of the fixing rod 11, which matches the center fixing hole 12. A second connecting hole 15 for bolt connection to the transformer 7 tank cover 3 is opened on the bottom wall at the other end of the fixing rod 11. The second connecting hole 15 matches the original bolt hole on the transformer 7 tank cover 3 below. That is, one end of the fixing rod 11 is connected to the vertical frame and the other end is connected to the transformer 7 tank cover 3 below.

[0029] In order to make the vertical frame of this embodiment adaptable to transformers of different sizes, the above-mentioned lower fixing hole 9, upper fixing hole 10, middle fixing hole 12, first connecting hole 14, and second connecting hole 15 are set to multiple, and the size of their hole spacing can be set according to actual needs.

[0030] To ensure the stability of the vertical frame structure, an internal connecting rod 13 is connected between the first frame 5 and the second frame 6. Specifically, a horizontally arranged internal connecting rod 13 is connected between the two vertical frames on the same side of the first frame 5 and the second frame 6. Several third connecting holes 16 are opened at both ends of the internal connecting rod 13, which can be bolted to the center fixing hole 12. At this time, the number of center fixing holes 12 on the vertical frame should be at least two, so that the vertical frame can be connected and fixed to the fixing rod 11 and the internal connecting rod 13 respectively.

[0031] In the batch transportation of transformers, there are multiple sets of fixing frames according to this embodiment. An external connecting rod (not shown in the figure) can also be provided between the fixing frames. The external connecting rod is horizontally positioned between the fixing frames to fix adjacent fixing frames. Specifically, each end of the external connecting rod has several fourth connecting holes (not shown in the figure) that can be bolted to the center fixing hole 12, so that one end of the external connecting rod connects to the vertical frame of one fixing frame, and the other end connects to the vertical frame of another fixing frame placed adjacent to this fixing frame. At this time, the number of center fixing holes 12 on the vertical frame should be at least three, allowing the vertical frame to be connected and fixed to the fixing rod 11, the internal connecting rod 13, and the external connecting rod, respectively. The length of the external connecting rod can be set according to the actual situation such as the placement distance between two adjacent fixing frames.

[0032] The aforementioned third connecting hole 16 and fourth connecting hole are configured in multiple ways, and the size of each hole spacing can be set as needed; to further improve the accuracy of the positional correspondence between the holes, the shape of the third connecting hole 16 and fourth connecting hole can be selected as an oblong hole, so that the position of the bolt can be finely adjusted.

[0033] A support portion 17 is fixedly provided at the lower end of the vertical frame. The support portion 17 provides horizontal stability to the vertical frame, preventing it from swaying during transportation. In this embodiment, the support portion 17 consists of a support rod fixed to the lower end of the vertical frame. The support rod is horizontally positioned, can contact the ground, and is perpendicular to the plane of the first or second frame. The support rod can be directly fixed to the lower end of the vertical frame by welding. The support portion 17 can also consist of two cross-arranged support rods. Of course, the support portion 17 can also adopt other support structures from the prior art.

[0034] To reduce manufacturing costs, the vertical frame is welded from channel steel, and the fixing rod 11, internal connecting rod 13, and external connecting rod are also made of channel steel. The structure of the channel steel facilitates the drilling of bolt holes and can meet the strength and other performance requirements of the fixing frame.

[0035] When using this embodiment, as Figure 3As shown, the lower transformer is placed in the designated position, and the first frame 5 is installed on the side perpendicular to the base rod 4 fixed at the bottom of the transformer. Specifically, the lower fixing hole 9 of the first frame 5 is fixed with bolts and nuts to the bolt holes of the transformer base rod 4. Then, the fixing rod 11 is installed, and the first connecting hole 14 and the middle fixing hole 12 on the fixing rod 11 are fixed with bolts and nuts. The fixing position of the fixing rod 11 should be above the edge of the transformer tank cover 3 and in contact with the transformer tank cover 3, so that the second connecting hole 15 can be aligned with a bolt hole on the edge of the transformer tank cover 3. Before alignment, the bolt and nut in the bolt hole have been removed. After alignment, the second connecting hole 15 is fixed with the bolt hole on the edge of the cover with bolts and nuts. At this time, the fixing of the first frame 5 is completed. Then, the second frame 6 on the other side is installed in the same way. At this time, the lower transformer 7 is fixed by the first frame 5 and the second frame 6. Finally, the upper transformer is placed on top of the first frame 5 and the second frame 6, and the bolt holes of the upper transformer's base rod 4 are fixed to the upper fixing holes 10 of the first frame 5 and the second frame 6 with bolts and nuts, thus completing the fixing of the upper transformer. An internal connecting rod 13 is connected and fixed between the first frame 5 and the second frame 6, and an external connecting rod is connected and fixed between adjacent frames.
