Upright high-voltage line maintaining ladder
The invention discloses an upright high-voltage line maintaining ladder. A supporting seat of the upright high-voltage line maintaining ladder is fixed through being matched with an outer conical surface located at the lower end of a supporting column body through a middle inner conical hole, and the outer conical surface of the supporting column body is fixed through being matched with the inner conical surface of the inner conical hole of the supporting column body; the inner conical surface and the outer conical surface which are fitted are automatically locked through the matching of a locking slot in the inner conical surface and the locking end of a right-angled body after the inner conical hole is fixed through being matched with the outer conical surface; and the surface of the supporting column body is fixedly provided with steps on which antiskid rubber is adhered, and antiskid rubber is also adhered to the bottom of the supporting seat. The upright high-voltage line maintaining ladder is simple in structure and very convenient to assemble and use, and no tools are needed in the assembling and disassembling processes when the ladder is used; after the upright serially-connected high-voltage line maintaining ladder is adopted, the problems on the aspects of uprightly climbing and standing of high-voltage line maintaining personnel are solved, and the high-voltage line maintaining ladder is rapid, convenient, safe and reliable to assemble and convenient to climb when being used for climbing; and after being used, the upright high-voltage line maintaining ladder is conveniently disassembled, packaged and transported, so that the production and use costs are reduced.
