Description

Technical Field

[0001] The invention relates to the field of transformers, in particular to an integral lifting device for a large transformer cooling device. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core. Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc.

[0003] When the transformer is running, a lot of heat will be generated inside the transformer, causing the transformer temperature to rise. The heat will be transferred to the cooling oil through the coil and the core. The cooling oil will then pass through the cooling device to dissipate the heat into the air. The cooling device can ensure that the transformer can operate within a reliable and safe temperature range and extend the service life of the transformer. It is an essential component for the operation of the transformer. However, since the cooling device needs to be disassembled and reassembled in each link of the transformer's initial trial installation, testing, transportation and on-site installation, a lot of manpower and material resources are wasted.

[0004] Therefore, an integral lifting device for a large transformer cooling device is proposed to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide an integral lifting device for a large transformer cooling device in order to solve the above problems, thereby improving the problem that the cooling device in the traditional transformer needs to be constantly disassembled and assembled during lifting and transportation, which consumes manpower and time.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] When implementing: Figure 1-4 As shown, a large transformer cooling device integral lifting device comprises: a bracket 1 and a collector 2 respectively arranged above and inside the bracket 1; a support assembly 4, the support assembly 4 is arranged on both sides of the bracket 1 and can support and position the sheet;

[0025] It should be noted that: after the installation of the pieces and the connection valve 3 are completed, the two manifolds 2 can be connected to the upper and lower parts of the transformer respectively through the re-piping lines. The re-piping lines can be directly installed at both ends of the two manifolds 2, or other pipe joints can be welded at the upper and lower parts of the two manifolds 2 for connection;

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the support assembly 4 includes a pull screw 401 arranged on the surface of the bracket 1, a support plate 402 is arranged below the pull screw 401, a contact shell 403 is arranged on the surface of the pull screw 401, and a two-way synchronous debugging rod 404 is movably connected to one side of the contact shell 403 through a rotating shaft; a plurality of pipe joints are welded on the surfaces of the two manifolds 2, wherein a connecting valve 3 for connecting with the sheet is installed in the pipe joint; the support plate 402 is set as a stainless steel triangular plate, and the length of the support plate 402 is consistent with that of the manifold 2; four movable shells 405 are arranged on one side of the manifold 2, and the movable shell 405 is arranged between the two connecting valves 3; two two-way synchronous debugging rods 404 are arranged, and the movable shell 405 is movably connected between the other ends of the two two-way synchronous debugging rods 404 through a rotating shaft, and one side of the movable shell 405 is fixedly connected to the manifold 2 inside the bracket 1;

[0027] It should be noted that the bidirectional synchronous debugging rod 404 is composed of two screw rods and a sleeve. The two screw rods are located between the sleeves. The threads of the two screw rods are arranged in opposite directions. The inner wall of the sleeve is provided with a pattern matching the screw rods. When the sleeve is turned forward, the two screw rods move away from each other. Similarly, when the sleeve is turned in the reverse direction, the two screw rods move closer to each other.

[0028] First, adjust the height of the support plate 402 on the surface of the pull screw 401 according to the position of the sheet after installation. After the adjustment is completed, screw the nut to the lower end of the pull screw 401 to position the support plate 402. Finally, raise the two two-way synchronous adjustment rods 404, one of which is angled upward, and the other is set horizontally. The two-way synchronous adjustment rod 404 with an upward angle can resist the pull screw 401 through extended adjustment, thereby improving the supporting strength of the pull screw 401. At the same time, it can also be used to adjust the angle of the pull screw 401 in the later stage. The horizontal two-way synchronous adjustment rod 404 can abut and limit the lower end of the pull screw 401, thereby improving the supporting effect of the pull screw 401 and the support plate 402 on the sheet;

[0029] A hanging plate 5 is arranged on the upper surface of the bracket 1, and a hanging hole is opened on the surface of the hanging plate 5;

[0030] The surface of the support plate 402 is provided with holes corresponding to the number of the pull screws 401, and the lower ends of the pull screws 401 penetrate into the holes of the support plate 402;

[0031] The lower end of the pull screw 401 passes through the hole of the support plate 402. When personnel need to install the sheet-type scatterers of different sizes, they only need to move the support plate 402 upwards on the surface of the pull screw 401 to the bottom of the sheet-type scatterer according to the installation height of the corresponding connecting valve 3 of the sheet-type scatterer, and then use the nut to lock the lower side of the support plate 402 on the surface of the pull screw 401, so as to achieve the effect of positioning the support plate 402, which can effectively improve the overall practicality and adaptability of the device;

[0032] Working principle: First, install the two manifolds 2 to the inside and top of the bracket 1 respectively, and set the connecting valve 3 on the surface of the manifold 2. Then install the plate slack on one side of the connecting valve 3. At this time, the personnel can adjust the height of the support plate 402 on the surface of the pull screw 401 through the position of the plate slack after installation. After the adjustment is completed, screw the nut to the lower end of the pull screw 401 to position the support plate 402. Finally, raise the two two-way synchronous debugging rods 404, one of which is angled upward and the other is horizontally set. The two-way synchronous debugging rod 404 with an upward angle passes The extended debugging can resist the pulling screw 401, improve the supporting strength of the pulling screw 401, and can also be used to adjust the angle of the pulling screw 401 in the later stage. The horizontal two-way synchronous debugging rod 404 can abut and limit the lower end of the pulling screw 401, thereby improving the supporting effect of the pulling screw 401 and the supporting plate 402 on the scattered pieces. After the scattered pieces are installed, the entire cooling system is completed. When the cooling system needs to be transferred in the subsequent stages such as the initial trial installation, testing, transportation and on-site installation of the transformer, it only needs to be lifted and transported using the lifting plate 5 without re-disassembly and reassembly.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
