The embodiment of the invention provides a control method and device for a lifting mechanism, a processor and a readable storage medium, and belongs to the technical field of engineering equipment. The method comprises the steps that the system pressure value of a hydraulic system and the first dip angle value of a shear fork connecting rod are obtained, and the system pressure value comprises the inlet pressure value of a telescopic oil cylinder and the front end pressure value of an electromagnetic proportional valve; determining a target pressure value based on the first dip angle value and a preset lifting speed; determining an oil cylinder flow value of a telescopic oil cylinder based on the target pressure value and a system pressure value; determining a target rotating speed of the driving motor based on the oil cylinder flow value; and controlling the driving motor to operate at the target rotating speed until the system operates stably. The target rotating speed of the driving motor is further determined by comparing the system pressure value obtained in real time with the oil cylinder flow value calculated by the first inclination angle value, real-time control over the lifting speed of the working platform is achieved, and the operation stability and use safety of the working platform are improved.
