Description

Technical Field

[0001] This invention belongs to the technical field of transformer manufacturing equipment, specifically relating to an integrated transformer cooler assembly and its transfer device. Background Technology

[0002] Transformers and coolers are inseparable core components in power systems. Simply put, transformers are responsible for transmitting electrical energy and transforming voltage, while coolers are responsible for dissipating the heat generated by the transformer during operation, ensuring its safe operation.

[0003] For large-capacity transformers with multiple cooler groups, the installation of coolers requires transporting and installing each cooler individually onto the transformer body. This means the cooler installation is done one unit at a time, hoisting them one by one. During the installation process, the installation of other components of the transformer body is halted. This method is not only time-consuming and lengthy, but the transportation, positioning, and securing of each cooler requires repeated allocation of lifting equipment, specialized installation personnel, and auxiliary tooling, resulting in a significant drain on equipment and human resources. Furthermore, the turnover, temporary storage, and individual installation of multiple coolers occupy a large amount of space in the transformer installation area, further exacerbating the pressure on site scheduling. Especially in confined installation spaces, this can easily lead to overlapping and interfering work processes, severely hindering construction efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a transformer integrated cooler assembly and its transfer device that are simple in structure and reasonably designed in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: In a first aspect, the present invention provides a transformer integrated cooler assembly, including a cooler assembly body, a frame and a mounting bracket. Multiple cooler assembly bodies are provided, and the multiple cooler assembly bodies are fixedly mounted on the mounting bracket. The mounting bracket is fixedly mounted on the frame. When the frame is in the installation position, the cooler assembly body is located on the side of the frame away from the transformer body.

[0006] As a further optimization of the present invention, the frame is fixedly mounted on an integral mounting bracket, and the frame is fixedly mounted on the transformer body by the integral mounting bracket.

[0007] As a further optimization of the present invention, a transformer bracket is fixedly provided on one side of the transformer body, and an overall mounting bracket is correspondingly provided with the transformer bracket. When the frame is in the installation position, the overall mounting bracket and the transformer bracket are fixedly installed.

[0008] As a further optimization of the present invention, multiple mounting supports are provided, and the multiple mounting supports are symmetrically arranged on both sides of the corresponding cooler assembly body.

[0009] As a further optimization of the present invention, the frame has a manifold for circulating oil between the cooler assembly body and the transformer body.

[0010] As a further optimization of the present invention, a support fixing seat is fixedly installed at the bottom of the frame, and multiple support fixing seats are provided, which are arranged in an orderly manner along the arrangement direction of multiple cooler assembly bodies.

[0011] As a further optimization of the present invention, the upper end face dimension of the support fixing seat is smaller than the lower end face dimension of the support fixing seat.

[0012] As a further optimization of the present invention, the center of gravity of the support fixing seat is located on the side of the frame facing the cooler assembly body.

[0013] Secondly, the present invention also provides a transfer device for an integrated transformer cooler assembly, applied to the aforementioned integrated transformer cooler assembly. The transfer device includes a transfer mechanism for transferring the integrated cooler assembly to the installation position of the transformer. The transfer mechanism includes a transfer trolley and an installation platform, and the integrated cooler assembly is placed on the installation platform.

[0014] As a further optimization of the present invention, the installation platform is a lifting and adjusting mechanism, the output end of which has a horizontally placed platform, and the support and fixing seat of the integrated cooler assembly is placed flat on the horizontally placed platform.

[0015] The present invention has at least the following beneficial effects: The present invention provides an integrated transformer cooler assembly and its transfer device. The integrated cooler assembly includes a cooler assembly body, a frame and a mounting bracket. By pre-installing multiple cooler assembly bodies on the mounting brackets on the frame, and then transferring the frame as a whole onto the transformer body, multiple cooler assembly bodies can be assembled individually, saving transformer installation space, simplifying the installation process of the transformer cooler assembly, reducing the input of workers, and improving the performance of the installation process. Moreover, the frame is fixedly installed with an overall mounting bracket. The frame is fixedly installed on the transformer body through the overall mounting bracket. By fixing the mounting bracket to the transformer bracket, the pre-assembled multiple cooler units can be moved to the installation position as a whole and connected to the transformer body in one go. That is, during installation, it can be directly aligned and positioned without repeated adjustments and calibrations, which significantly shortens the overall construction cycle. It is especially suitable for installation scenarios with limited space and multiple processes running in parallel. In addition, a support base is fixedly installed at the bottom of the frame. The upper end face of the support base is smaller than the lower end face, while the lower end face is larger, which can form a larger contact area with the ground. This effectively prevents the support base from sinking into soft ground or platform surface, ensuring that the frame is placed stably without tilting or shaking during the installation of the cooler body on the frame.

It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

Therefore, they should not be construed as limitations on this application.

[0020] like Figure 1 , Figure 2As shown, the present invention provides an integrated transformer cooler assembly, including a cooler assembly body 11, a frame 5, and a mounting bracket 7. Multiple cooler assembly bodies 11 are provided, and multiple cooler assembly bodies 11 are fixedly mounted on the mounting bracket 7. The mounting bracket 7 is fixedly mounted on the frame 5. When the frame 5 is in the installation position, the cooler assembly body 11 is located on the side of the frame 5 away from the transformer body.

[0021] By pre-installing multiple cooler unit bodies 11 on the frame 5, and then moving the frame 5 as a whole onto the transformer body, multiple cooler unit bodies 11 can be assembled individually, saving transformer installation space, simplifying the installation process of transformer cooler units, reducing manpower input, and improving installation process performance.

[0022] For example, see [link to relevant documentation]. Figure 2 and Figure 3 The frame 5 is fixedly mounted with an integral mounting bracket 8, and the frame 5 is fixedly mounted on the transformer body via the integral mounting bracket 8. Specifically, a transformer bracket 10 is fixedly installed on one side of the transformer body, and the integral mounting bracket 8 is correspondingly installed with the transformer bracket 10. When the frame 5 is in the installation position, the integral mounting bracket 8 and the transformer bracket 10 are fixedly installed. Through the corresponding fixing of the integral mounting bracket 8 and the transformer bracket 10, multiple pre-assembled cooler unit bodies 11 (already fixed to the frame 5) can be moved to the installation position as a whole, and the connection with the transformer body can be completed in one go. That is, during installation, it can be directly aligned and positioned without repeated adjustments and calibrations, significantly shortening the overall construction cycle, and is especially suitable for installation scenarios with limited space and multiple parallel processes.

[0023] For example, see [link to relevant documentation]. Figure 2 and Figure 3 Multiple mounting supports 7 are provided, and the multiple mounting supports 7 are symmetrically arranged on both sides of the corresponding cooler assembly body 11. The cooler assembly body 11 is limited between the mounting supports 7 by the symmetrically arranged mounting supports 7. The mounting supports 7 serve as the connection medium of the frame 5 of the cooler assembly body 11. The symmetrical arrangement structure can provide a clear installation reference for the cooler assembly body 11. Specifically, the installation stability of the cooler assembly body 11 is achieved by bolting the mounting ears on both sides of the cooler assembly body 11 to the mounting supports 7.

[0024] Continue reading Figure 3The frame 5 has a manifold 9, which is used to circulate the oil between the cooler assembly body 11 and the transformer body. Specifically, the manifold 9 is integrated into the frame 5 and assembled with the frame 5 as a whole. Each cooler assembly body 11 is provided with an oil inlet and an oil outlet. The manifold 9 is divided into two paths: an "oil inlet manifold" and an "oil outlet manifold". The oil inlets of all cooler assembly bodies 11 are connected to the "oil inlet manifold" through branch pipes, and the oil outlets of all cooler assembly bodies 11 are connected to the "oil outlet manifold" through branch pipes, realizing parallel connection of multiple coolers and ensuring that each cooler can obtain a stable oil flow supply.

[0025] For further reference Figure 2 and Figure 3 The bottom of the frame 5 is fixedly equipped with a support base 6, and multiple support bases 6 are provided, which are arranged in an orderly manner along the arrangement direction of multiple cooler assembly bodies 11. Thus, before all cooler assembly bodies 11 are installed, the frame 5 can be placed stably on the ground with the help of the support bases 6, which facilitates the subsequent installation of the cooler assembly bodies 11 on the frame 5.

[0026] For example, see [link to relevant documentation]. Figure 3 The upper surface dimension of the support base 6 is smaller than the lower surface dimension of the support base 6. The core function of the support base 6 is to support the overall weight of the frame 5 and the multiple cooler unit bodies 11. The larger lower surface dimension allows for a larger contact area with the ground. According to the principle of force, the larger the contact area, the smaller the pressure per unit area. This effectively prevents the support base 6 from sinking into soft ground (such as ground that is not fully hardened on the construction site) or the platform surface, ensuring that the frame 5 is placed stably without tilting or shaking.

[0027] Moreover, such as Figure 3 As shown, the center of gravity of the support base 6 is located on the side of the frame 5 facing the cooler assembly body 11. Since multiple cooler assembly bodies 11 are concentrated on the outside of the frame 5, the center of gravity of the overall structure is naturally biased towards the cooler side. The center of gravity of the support base 6 is actively biased towards the cooler side (outer side), which is equivalent to adding an "outer counterweight" at the support end. This can form a counterbalancing torque with the outer center of gravity of the cooler assembly body 11, offsetting part of the overturning force, so that the overall center of gravity of the structure falls within the support range of the support base 6 (rather than biased towards the outer edge), significantly improving the standing stability. Whether it is temporarily stored on the ground, transported under bumps, or installed and connected, it can effectively resist external interference and avoid the risk of tipping over.

[0028] In another embodiment, the present invention also provides a transfer device for an integrated transformer cooler assembly, applied to the aforementioned integrated transformer cooler assembly. The transfer device includes a transfer mechanism 2, which is used to transfer the integrated cooler assembly to the installation position of the transformer. The transfer mechanism 2 includes a transfer trolley 3 and an installation platform 4, and the integrated cooler assembly is placed on the installation platform 4.

[0029] Among them, the installation platform 4 is a lifting and adjusting mechanism, and the output end of the lifting and adjusting mechanism has a horizontally placed platform. The support and fixing seat 6 of the integrated cooler group is placed flat on the horizontally placed installation platform 4.

[0030] After multiple cooler unit bodies 11 are pre-installed on the frame 5, the integrated cooler unit is hoisted onto the installation platform 4 and the support fixing seat 6 is fixed to the installation platform 4. At this time, with the help of the transfer trolley 3, the installation platform 4 carries the integrated cooler unit to one side of the transformer bracket 10 on the transformer body. Then, by adjusting the height of the installation platform 4, the installation height of the transformer bracket 10 is consistent with that of the overall installation bracket 8, so that the overall installation bracket 8 can be successfully installed on the transformer bracket 10.

[0031] In other embodiments, the support fixing base 6 is first fixed to the mounting platform 4, and then multiple cooler assembly bodies 11 are pre-installed on the frame 5. Then, the transfer trolley 3 is driven, and the mounting platform 4 carries the integrated cooler assembly to one side of the transformer bracket 10 on the transformer body. At this time, the height position of the mounting platform 4 is adjusted so that the installation height position of the transformer bracket 10 is consistent with that of the overall mounting bracket 8, so that the overall mounting bracket 8 can be successfully installed on the transformer bracket 10.

[0032] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
