[0003] In order to ensure comprehensive protection, stairwells in residential buildings or office buildings need to carry out some monitoring, fire protection and other installation work. These things are generally installed at a high position, and workers need to use an operating platform to install them. The existing stairwell operating platform is generally a combined frame structure and does not have the ability to move. When moving between floors, workers are generally required to manually carry the stairs. The transportation of each floor is time-consuming and labor-intensive, which greatly affects the construction efficiency. Utility Model Content

[0004] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A stair operating platform with automatic climbing function comprises a platform frame, a lifting mechanism, a transmission mechanism, a driving climbing wheel and a moving climbing wheel. The platform frame is an operating platform and a working platform for workers to work in the stairwell. The lifting mechanism is arranged at the bottom of the platform frame.

The wheel frame is a cross-shaped structure with four equal ends, and the inner side of the end of each end is rotatably provided with a climbing wheel. Because the wheel frame is a cross structure, the angles between adjacent climbing wheels are all ninety degrees. When the wheel frame rotates as a whole, the adjacent climbing wheels will touch the top side of the step on the stairs in turn. Under the action of the driving force, the wheel frame The lifting of the lifting device is assisted by a lifting device, and the lifting device is connected with the lifting device to the lifting device to the lifting device, and the lifting device is connected with the lifting device to the lifting device to the lifting device, so that the lifting device can be turned off and the rest of the stairs can be turned off.
