The invention provides a perforation robot which is provided with a self-climbing rail and can realize all-around perforation in a building. The perforation robot is used as a decoration engineering robot, achieves the goals of freely walking to a specified position through a self program control walking trolley, and moves an impact drill to the corresponding direction and position of the perforation operation through a perforation module and a self-climbing rail-provided tensioning frame arranged on the program control walking trolley; operations such as perforation in a ceiling board, perforation in a side wall surface and perforation in the ground can be realized; and after a tensioning fixing mode is used for fixation, the operation of perforation in the building is completed through the perforation module, wherein the self-climbing rail-provided tensioning frame can ascend or descend according to the height of the building; and in order to realize the precise alignment of the perforation position, the perforation position is confirmed through a laser beam emitted by an infrared crossed laser beam generator arranged on the perforation module. In the whole perforation operation process, the all-around perforation operation on the building can be completed only through manually confirming the precise perforation position on the ground.
