[0002] In the routine inspection and maintenance of power equipment, especially for the replacement of current transformers (CTs) and voltage transformers (PTs) at voltage levels of 35kV and above, auxiliary hoisting or support devices are often required. In recent years, with the advancement of intensive maintenance in power systems, the quality problems of aging equipment have become increasingly prominent, with frequent failures such as CT saturation and equipment damage, leading to a significant increase in the replacement frequency of CTs and PTs.

[0003] Currently, common maintenance support methods mainly include cranes, single-pole climbing poles, or tripod-type lifting point devices. However, in actual substations or distribution rooms, due to limited space, cranes often cannot enter the work area. Using climbing poles or tripod structures requires high lifting point heights, involves long poles, is inconvenient to transport, and has a cumbersome installation process. Furthermore, there is a risk of tipping over during operation, which can easily cause equipment damage or personal injury. In addition, existing devices lack flexible adjustment capabilities and cannot be adapted to the site environment, resulting in low maintenance efficiency and difficulty in meeting the diverse and complex operational needs. Summary of the Invention

[0004] In view of the aforementioned problems that existing devices lack flexible adjustment capabilities and cannot be adapted to the site environment, resulting in low maintenance efficiency and difficulty in meeting the operational needs under diverse and complex working conditions, this invention is proposed.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include the three-dimensional spatial dimensions of length, width, and depth.

[0029] Example Reference Figure 1 - Figure 6According to an embodiment of the present invention, an adjustable auxiliary device is provided. This device includes a mobile platform 1, including a support member 11; and an adjustment component 2 disposed on the mobile platform 1. The adjustment component 2 includes a positioning member 21 disposed on the support member 11, and a primary adjustment member 22 disposed on the positioning member 21. The primary adjustment member 22 moves within the range of the support member 11 by being limited by the positioning member 21. A secondary adjustment member 23 is disposed on the primary adjustment member 22. The secondary adjustment member 23 is adjusted on the primary adjustment member 22 to be flush with the bottom of the support member 11. As the primary adjustment member 22 and the secondary adjustment member 23 move, they are used to increase the force-bearing points of the support member 11.

[0030] Reference Figure 3 The positioning component 21 includes a first positioning plate 211 and a second positioning plate 212 fixedly installed on the carrier 11. The first positioning plate 211 and the second positioning plate 212 are spaced apart. The first positioning plate 211 and the second positioning plate 212 are fixed on the frame 111 on the carrier 11, so as to facilitate the installation of the rotating component 3 and the lifting component 4 on them.

[0031] Reference Figure 1 and Figure 2 In this embodiment, the carrier 11 includes a frame 111 for fixed installation of the first positioning plate 211 and the second positioning plate 212. The bottom of the frame 111 is equipped with rollers 112, and a handle 113 is installed on one side of the frame 111. The frame 111 has a gate-shaped structure with an opening on one side. The first positioning plate 211 and the second positioning plate 212 are installed on the frame 111, and the first positioning plate 211 and the second positioning plate 212 do not touch the ground. The rollers 112 are located at the four corners of the frame 111 and adopt a combination design of directional wheels and universal wheels, which facilitates movement within the station and can bear the load when the device is moved. The handle 113 is made of stainless steel and is set on the side of the frame 111. The overall structure is a gate-like structure with an arc-shaped upper part, which facilitates manual operation and saves effort.

[0032] In this embodiment, the primary adjustment member 22 includes a first adjustment plate 221 rotatably connected to the first positioning plate 211, and a second adjustment plate 222 rotatably connected to the first positioning plate 211. The first adjustment plate 221 and the second adjustment plate 222 are spaced apart. The first adjustment plate 221 and the second adjustment plate 222 are located below the first positioning plate 211 and are not in contact with the ground like the support member 11. The first adjustment plate 221 and the second adjustment plate 222 can be rotated and adjusted in position as needed below the first positioning plate 211. Reference Figure 4In this embodiment, the first adjusting plate 221 and the second adjusting plate 222 can rotate arbitrarily within the frame 111 to achieve different position changes, thereby increasing the stress points within the frame 111 and improving the load-bearing capacity of the frame 111. With the addition of the first adjusting plate 221 and the second adjusting plate 222, the stress points of the entire frame 111 are not only the frame 111 itself. By adding the first adjusting plate 221 and the second adjusting plate 222 to the frame 111, multiple load-bearing modes of different shapes can be formed. The first adjusting plate 221 and the second adjusting plate 222 are both parallel to the two sides of the frame 111, which can form a parallel mode with a reduced gap to facilitate the placement of small objects. The first adjusting plate 221 and the second adjusting plate 222 can also be moved to contact each other, which can form a stable triangular shape mode.

[0033] Reference Figure 1 - Figure 3 In this embodiment, the secondary adjustment component 23 includes a first adjusting bolt 231 connected to one side of the first adjusting plate 221, a second adjusting bolt 232 connected to one side of the second adjusting plate 222, a first support plate 233 mounted on the first adjusting bolt 231, and a second support plate 234 mounted on the second adjusting bolt 232. The first adjusting bolt 231 can be rotated up and down on the first adjusting plate 221 to adjust its position. Similarly, the second adjusting bolt 232 and the second adjusting plate 222 can also be rotated up and down to adjust their positions. The first support plate 233 and the second support plate 234 are respectively mounted on the first adjusting bolt 231 and the second adjusting bolt 232, and the first support plate 233 and the second support plate 234 can also be displaced up and down on the first adjusting plate 221 and the second adjusting plate 222.

[0034] Therefore, when the device stops moving, the first support plate 233 and the second support plate 234 can move to be close to the ground, just like the rollers 112 on the frame 111. This increases the friction when the first support plate 233 and the second support plate 234 are in contact with the ground, thereby improving the stability of the device in its fixed state.

[0035] The aforementioned secondary adjustment component 23 can also be understood as follows: when the device is moved, the first adjustment bolt 231 and the second adjustment bolt 232 can be removed so that the first adjustment plate 221 and the second adjustment plate 222 do not affect the movement of the device. Alternatively, the first adjustment bolt 231 and the second adjustment bolt 232 can be rotated upwards so that they do not contact the ground, thus not affecting the movement of the device. When the first adjustment bolt 231 and the second adjustment bolt 232 move upwards and the exposed part increases, the device can provide additional protection when carrying objects.

[0036] Reference Figure 5In another embodiment, the secondary adjustment member 23 may also include a toothed groove 235 formed on the first support plate 233 and the second support plate 234. As the first adjustment plate 221 moves relative to the first support plate 233 and the second adjustment plate 222 moves relative to the second support plate 234, the toothed groove 235 of the first support plate 233 and the toothed groove 235 of the second support plate 234 and the first support plate 233 and the second support plate 234 engage with each other, so that the first adjustment plate 221 and the second adjustment plate 222 are connected, further improving the stability of the first adjustment plate 221 and the second adjustment plate 222.

[0037] Reference Figure 1 and Figure 6 In this embodiment, the positioning component 21 on the adjustment component 2 is also provided with a rotating component 3. The rotating component 3 includes a limiting plate 31 installed on the positioning component 21, a rotating component 32 installed on the limiting plate 31, a support arm 33 installed on the rotating component 32, and the rotating component 32 fixedly installed on the support arm 33. The support arm 33 is rotatably connected to the limiting plate 31. The rotating component 3 improves the flexibility of the device and increases the working range. The rotating component 32 includes a rotating disk 321 fixedly installed on the limiting plate 31, a driver 322 installed on the rotating disk 321, and the support arm 33 and the driver 322 fixedly installed. The support arm 33 is rotatably connected to the rotating disk 321 on the limiting plate 31. Thus, when the driver 322 is activated, it drives the support arm 33 to rotate on the rotating disk 321.

[0038] In this embodiment, a lifting assembly 4 is installed on the rotating assembly 3. The lifting assembly 4 includes a hydraulic valve 41 installed on the rotating component 32, an extension component 42 connected to the hydraulic valve 41, and a hook 43 installed on the extension component 42. The extension component 42 includes an upper and lower adjusting rod 422 connected to the hydraulic valve 41, and a front and rear adjusting rod 423 installed on the adjusting arm 421. The upper and lower adjusting rod 422 is hinged to the adjusting arm 421 and the support arm 33 respectively. The hook 43 is installed on the front and rear adjusting rod 423. The lower side of the upper and lower adjusting rod 422 is hinged to the lower side of the support arm 33, the upper side of the adjusting arm 421 is hinged to the upper side of the support arm 33, and the upper side of the upper and lower adjusting rod 422 is hinged to the adjusting arm 421. The hydraulic valve 41 can activate the upper and lower adjusting rod 422 and the front and rear adjusting rod 423 to move.

[0039] Therefore, by activating the hydraulic valve 41, the upper and lower adjusting rods 422 are raised, pushing the adjusting arm 421 to move upward. The front and rear adjusting rods 423 on the adjusting arm 421 can also be activated, allowing the hook 43 to detach from the adjusting arm 421 and extend to reach the object being worked on.

[0040] During operation, first push the handle 113 to move the device to the working position. The rollers 112 at the bottom of the frame 111 are a combination of directional wheels and swivel wheels, which are flexible and easy to push in the equipment area aisle. After it is in place, loosen the locking bolts on the first adjusting plate 221 and the second adjusting plate 222, and turn the two adjusting plates out from the bottom of the frame 111 to the sides or front. Adjust the angle of the first adjusting plate 221 and the second adjusting plate 222 according to the flatness of the ground and the load-bearing requirements, so that they contact the ground respectively. Then, unscrew the first adjusting bolt 231 and the second adjusting bolt 232, so that the first support plate 233 and the second support plate 234 are also lowered to the ground. The teeth 235 on the two support plates can mesh with each other when they move relative to each other, ensuring that the left and right adjusting plates are connected as one, increasing the support area. At this time, the frame 111, the adjusting plates and the support plates together form a stable force-bearing platform that will not shake or tip over.

[0041] Then start the driver 322 to make the support arm 33 rotate on the rotary table 321, align the lifting assembly 4 with the CT equipment to be replaced, operate the hydraulic valve 41 to control the upper and lower adjusting rods 422 to lift, and push the adjusting arm 421 to move upward; then control the front and rear adjusting rods 423 to extend, so that the hook 43 extends directly above the equipment, and hook the hook 43 to the lifting ring of the equipment.

[0042] Operate hydraulic valve 41 again, first slightly tighten the sling, and after confirming that the hook is secure, slowly lift the equipment. Using the coordination of the front and rear adjusting rods 423 and the upper and lower adjusting rods 422, smoothly pull the equipment out of the mounting base. By rotating the support arm 33, transfer the lifted equipment to the temporary placement area next to it, lower the equipment, and remove the hook 43.

[0043] When installing a new CT scanner, follow the reverse order: hook 43 onto the new equipment, lift it up, rotate the support arm 33 to the installation position, fine-tune the alignment using the up / down and front / back adjustment rods 423, slowly lower it, and tighten the base bolts.

[0044] After completion, retract the front and rear adjustment rods 423 and the up and down adjustment rods 422, rotate the support arm 33 back to the initial position, and screw up the first adjustment bolt 231 and the second adjustment bolt 232 to lift the first support plate 233 and the second support plate 234 off the ground. Then you can push the handle 113 to move the device.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
