The invention provides an elevator car roof driving balance structure with an adjustable counterweight position, which comprises a car frame, an upper main beam, a lower main beam, a first traction rope, a second traction rope, a first counterweight frame and a second counterweight frame, the upper main beam and the lower main beam are located above the car frame, and the lower main beam is connected to the upper main beam through a hinge part; the lower main beam can rotate relative to the upper main beam through the hinge part, and a certain angle is formed between the lower main beam and the upper main beam; the upper main beam is provided with an upper guide wheel set; the lower main beam is provided with a lower guide wheel set; a traction device is fixed to the top of the lift car frame; and a traction wheel is arranged on the traction device. The installation angle of the upper main beam and the installation angle of the lower main beam are variable, the requirements of variousinstallation spaces for various installation modes can be met, and installation is flexible. According to the elevator car roof driving balance structure with the adjustable counterweight position provided by the invention, the counterweight space can be flush with the guide rail space, the occupied thickness space is reduced, and the requirement influence on the height of a hoistway is reduced. The stress distribution of the car frame is more reasonable, and the comfort of an elevator is improved.
