Moreover, the tools required for overhauling can only be carried, and it is not convenient to take the tools from the ladder.

[0004] In the present application, an overhauling platform for a transformer substation is provided, which comprises a support column. The support column is mainly composed of a plurality of assembled short columns arranged in a vertical direction. Adjacent two assembled short columns are detachably connected. The height of the support column can be adjusted by increasing or decreasing the number of the assembled short columns. A support plate is arranged at the bottom end of the support column to contact the ground. An overhauling table is arranged on the front side of the support column in a vertical sliding manner. Guardrails are arranged around the overhauling table. A fixed pulley is arranged at the upper end of the support column. A winding roller with a steel cable wound thereon is arranged on the rear side of the support column. The rotation shaft of the winding roller is in a horizontal direction. One end of the steel cable is wound on the winding roller, and the other end of the steel cable is connected to the overhauling table through the fixed pulley. A driving motor is arranged to drive the winding roller to rotate. The driving motor is used to control the lifting of the overhauling table.

[0005] In one embodiment, a connecting column is fixedly arranged on the upper end of each assembled short column, and an installation groove is arranged in the lower end of each assembled short column. The connecting column is inserted into the installation groove to achieve detachable connection between adjacent two assembled short columns.

[0006] In one embodiment, a sliding groove is arranged on the front side of the support column in a vertical direction. A sliding block is fixedly arranged on the overhauling table, and the sliding block is connected to the sliding groove in a vertical sliding manner.

[0007] In one embodiment, a counterweight is arranged on the support plate of the rear side of the support column.

[0008] In one embodiment, the guardrail is provided with an openable gate.

[0009] In one embodiment, the inspection platform is provided with a tool box for placing tools.

[0010] In summary, the application provides a maintenance platform for substations, which has the following advantages over the prior art:

[0011] (1) When the power equipment to be maintained is relatively high, the worker can go to the inspection platform, and the drive motor can control the inspection platform to reach the required height next to the maintenance position, making the maintenance work more convenient and labor-saving, and the tools needed for maintenance can be placed on the inspection platform for easy access.

[0012] (2) The height of the support column can be adjusted by increasing or decreasing the number of assembled short columns to adapt to different site conditions, which is more flexible. BRIEF DESCRIPTION OF DRAWINGS
