The invention discloses a screw type self-balancing operation platform for side slope construction. The screw type self-balancing operation platform comprises an elevator fixedly installed at the flat part of a slope crest and a fixing support, wherein the fixing support is located below the elevator; one end of a steel wire rope is connected to a slope operation trolley on a slope, and the other end of the steel wire rope winds around a fixed pulley on the fixing support for being connected to the elevator; in the slope operation trolley, front wheels and rear wheels are installed at the two ends of a rectangular frame body respectively, one front wheel and the rear wheel located on the same side as the front wheel are connected through a transmission shaft, the two sides of a square operation platform are connected to the transmission shafts through screw structures, and the screw structures are composed of hinged structures at the lower part and nut transmission systems horizontally arranged close to the front wheels. According to the screw type self-balancing operation platform for side slope construction, the operation platform can be always horizontal and adapt to side slope operation of different gradients. In addition, the operation platform is simple in structure and convenient to operate and can guarantee the safety of constructors.
