Movable supporting platform and urea synthesis tower hoisting device

The utility model relates to a mobile support platform and a urea synthesis tower hoisting device, the mobile support platform comprises a frame platform which can be used for supporting a horizontally placed urea synthesis tower, the bottom of the frame platform is provided with pulleys, and the pulleys are matched with tracks laid on the ground at the bottom of a structural frame; a gantry crane is fixedly arranged at one end of the frame platform. And the urea synthesis tower hoisting device comprises a movable supporting platform and a hydraulic lifter which is arranged at the top of the structural frame and is used for hoisting the urea synthesis tower. The frame platform in the movable supporting platform is adopted to move the urea synthesis tower, and the gantry crane is used for replacing an existing tail-slipping crane and is matched with hoisting equipment at the top of the structural frame, so that the urea synthesis tower is gradually lifted to be in a vertical state from a horizontal state, the
