Three-dimensional positioning platform based on substation operators

The invention discloses a three-dimensional positioning platform based on substation operators, belongs to the technical field of positioning platforms, and aims to solve the problems that the stability of a lifting platform becomes poor due to abrasion and aging of a lifting frame, the lifting platform is inconvenient to extend due to bearing force when a worker stands on the top of the lifting platform, soil near a telegraph pole is loose, and the working efficiency is low. The problem that the lifting platform is inconvenient to fix when being used is solved; the clamping mechanism comprises a first clamping assembly arranged on one side of the base and further comprises a second clamping assembly movably arranged on one side of the supporting table, the other end of a first sliding plate is fixedly connected with a first U-shaped plate, and the other end of a second sliding plate is fixedly connected with a second U-shaped plate; linkage is achieved through the first clamping assembly in the process of ti
