The invention discloses an intelligent pressure welding platform suitable to high voltage power transmission lines and belongs to the field of power delivery line construction devices. The platform includes a guide rail pressure welding carriage, a horizontal moving oil cylinder, a pressing jaw trolley, a pressing jaw, a displacement sensor, a gasoline engine hydraulic pump and a programmable controller. The guide rail pressure welding carriage includes a pedestal and a line clamp. The horizontal moving oil cylinder is arranged on the guide rail pressure welding carriage. The horizontal moving oil cylinder is connected to the gasoline engine hydraulic pump through a hydraulic pipe. The pressing jaw trolley is fixed on the horizontal moving oil cylinder. The pressing jaw is installed on the pressing jaw trolley and is connected to the gasoline engine hydraulic pump. The displacement sensor is disposed on the guide rail pressure welding carriage and is in separate connection to the pressing jaw trolley and the programmable controller. The programmable controller is connected to the gasoline hydraulic pump. Compared with prior art, the platform can use the programmable controller to realize digital control in the process of pressure welding, and a pressure sensor acquires pressure signals to achieve accurate control in the process of pressure welding. The platform increases construction efficiency, safety and reliability.
