The invention relates to a supporting head assembly. The supporting head assembly comprises a main frame, an oil tank arranged in the main frame, a controller, a pump station, a hydraulic motor, a threaded rod, a center hole jack and a bearing device; the center hole jack comprises a cylinder body and a piston, the center of the cylinder body is through, and a through center hole is formed in thecylinder body; the bearing device comprises a bearing piece, a ball head support clamped at the end of the bearing piece and a bearing plate connected to the bearing piece through the ball head support; the hydraulic motor and the threaded rod are arranged at the rear end of the center hole of the center hole jack, the bearing device is arranged at the front end of the center hole of the center hole jack. The front end of the piston abuts against the bearing piece, the controller is used for controlling the pump station to load or unload the center hole jack so as to drive the bearing device to move front and back, and the controller is also used for controlling the hydraulic motor to drive the threaded rod to advance and retreat forwards and backwards so as to lock or unlock the bearing device.
