Abstract

The invention relates to a pre-supporting mechanism and a tunneling machine. The pre-supporting mechanism is mounted on a rear support of the tunneling machine through a mounting seat, a telescopic main arm is arranged on the mounting seat, and a supporting top plate is hinged at the top of the telescopic main arm. The mounting seat is arranged on the rear support of the tunneling machine, the telescopic main arm is connected on the mounting seat, and the supporting top plate is hinged at the top of the telescopic main arm, so that the pre-supporting mechanism can swing without swinging along with a cutting portion, working of the tunneling machine is not affected, demounting of a cover plate of the tunneling machine is not impeded, and system maintenance of the tunneling machine is not affected; the pre-supporting mechanism does not need manual supporting, so that working intensity is reduced, and safety of working personnel can be effectively protected.
