The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model provides a transformer auxiliary installation device, such as Figure 1-4 As shown, the transformer auxiliary installation device includes: a base plate 1, on the top of which is fixedly mounted a first electric hydraulic rod 2 for regulating lifting; a mounting frame 3 arranged on the output rod of the first electric hydraulic rod 2; a retractable steel wire rope 4 arranged on the mounting frame 3; a hanger 5 fixed on the steel wire rope 4 for assisting in lifting a transformer body 8, on which a lifting rope 6 is symmetrically fixedly mounted, and a lifting hook 7 is fixedly mounted on the bottom end of the lifting rope 6; and a retracting mechanism arranged on the mounting frame 3 for retracting and releasing the steel wire rope 4.

[0023] It should be noted that the current reliance on large mechanical equipment such as cranes in the auxiliary installation of transformers does bring many challenges and limitations, which can be explained in detail from the following aspects: The crane needs sufficient working space to unfold the boom and perform precise operations. If the installation site is small, the movement and rotation of the crane will be restricted, which will affect the accurate placement of the transformer; buildings, trees or other obstacles that may exist on site will limit the field of view and operating range of the crane, increasing the difficulty and risk of operation; the weight of the crane itself plus the weight of the load imposes strict requirements on the bearing capacity of the ground. If the ground is soft or uneven, it may cause the crane to sink or tilt, and even rollover accidents may occur in severe cases; in some cases, temporary reinforcement of the ground may be required, which not only adds additional costs and workload, but may also extend the construction period; cranes are usually large in size and have specific requirements for road width and turning radius. Narrow or winding roads may prevent the crane from reaching the installation site; Road quality: Poor road conditions, such as potholes, mud or steep slopes, will affect the stability and safety of the crane; Severe weather conditions, such as strong winds, heavy rain, etc., will increase the risk of lifting operations, and operations may need to be suspended and wait for the weather to improve. Power lines: In urban or industrial areas, dense power lines may become obstacles to lifting operations, and special attention needs to be paid to avoid touching them; Due to the various restrictions mentioned above, the original installation plan may need to be adjusted frequently, resulting in project delays; Safety risks: Operating large-scale mechanical equipment itself has certain safety risks, and the uncontrollable factors of the external environment significantly increase the risk level of the entire installation process; In summary, the current transformer auxiliary installation relies on large-scale mechanical equipment such as cranes and does face multiple challenges. These challenges not only affect the installation efficiency and cost, but more importantly, increase the uncertainty and safety risks during the installation process.
