Description

Technical Field

[0001] The utility model relates to the technical field of maintenance platforms, in particular to a maintenance construction platform for distribution transformers. Background Art

[0002] The maintenance platform is used to assist maintenance personnel in performing maintenance on transformers at heights. However, the maintenance platform in the prior art has certain drawbacks when used. For example, the publication number: CN219591995U discloses "an insulated dry-type transformer matching maintenance tool, including a base, a scissor-type lifting platform is provided on the upper end surface of the base, a fence is fixedly connected to the scissor-type lifting platform, a door body is hingedly connected to one side of the fence by a hinge, a mounting groove is provided on the side wall of the door body, a storage mechanism for placing disassembled parts is provided in the mounting groove, and the support rod serves as a support member for the storage plate";

[0003] The device manually rotates the support rod, and stops rotating the support rod when the storage plate remains in a horizontal state. The support rod is then fixed by a set limit mechanism to support the storage plate. When the transformer is inspected and repaired, larger devices such as the transformer outer shell are removed, and then the devices are placed on the storage plate to inspect the internal components. The storage plate can be folded and stored in the installation groove when not in use, and will not take up space. The installation is convenient and quick when in use. However, many tools are required for transformer maintenance. Therefore, tools are placed in the installation groove before maintenance. When the device is used, the position of the installation groove remains unchanged relative to the maintenance personnel. For example, the maintenance personnel are facing the transformer and may have to take the tools with their backs turned, which makes it inconvenient for the staff to take the tools.
