The invention discloses an operation platform for tunnel top maintenance, and relates to the technical field of engineering construction equipment. The operation platform for tunnel top maintenance comprises a base and a working platform, wherein a first sliding support and a first fixed support are arranged on the base; a telescopic connecting rod is rotationally connected to the first sliding support and the first fixed support; the upper end of the telescopic connecting rod is rotationally connected with a second fixed support and a second sliding support; the upper end of the second fixedsupport is fixedly connected with the working platform; supporting rods are arranged at the four corners of the working platform and are tightly attached to the top of a tunnel; wheels at the lower end of the base are controlled to contract through a scissor jack, so that the four bottom feet of the base are in contact with and are tightly attached to the ground; the operation platform is ensuredto be fixed up and down; the stability of the operation platform is improved; the working efficiency is improved; and meanwhile, the operation platform can be prevented from being turned over, and theconstruction safety is improved.
