The utility model relates to the technical field of oil rigs, in particular to a long-distance hydraulic installation connecting mechanism. An inner cylinder of the long-distance hydraulic installation connecting mechanism is installed in a cylinder barrel and can slide in the cylinder barrel in a left-and-right mode under the effect of hydraulic oil, a pin is fixed in the inner cylinder, the pin and the inner cylinder can slide together, a centering mechanism is fixed in the pin, a connecting flange is installed on an end face of the cylinder barrel, an oil inlet and an oil outlet are formed on the cylinder barrel, and the cylinder barrel and the pin are sealed through a sealing ring. The long-distance hydraulic installation connecting mechanism can remotely complete stretching of a pin shaft and jointing of a whole set of device through hydraulic control, removes damagers of manual operation and overcomes the shortcoming that the existing operation of high-position installation of the connecting pin is high
