The invention belongs to the technical field of tunneling equipment, and particularly provides a special-shaped tunnel corner excavation device and a tunneling machine. The excavation device comprises a main beam, a movable seat capable of moving front and back is installed on the main beam, installation frames used for installing a rock breaking device are installed on the left side and the right side of the movable seat, and each installation frame is provided with a leveling compensation mechanism used for adjusting the horizontal angle of the corresponding installation frame so as to compensate the offset of the wheel type trailer. The main beam is provided with a hinged connection portion used for being hinged to a wheel type trailer, one end of the leveling driving device is used for being connected with the main beam, the other end of the leveling driving device is used for being connected with a wheel type supporting trailer, or the installation frame is hinged to the movable base, one end of the leveling driving device is used for being connected with the installation frame, and the other end of the leveling driving device is used for being connected with the movable base. The heading machine comprises the excavating device. The rock breaking device can be driven to rotate through the leveling compensation mechanism, it is guaranteed that the rock breaking device is horizontal, and the shape of an excavated section is guaranteed. And meanwhile, the rock breaking device can actively escape.

    本发明属于掘进设备技术领域,具体提供了一种异形隧道边角开挖装置及掘进机。该开挖装置包括主梁,主梁上安装有可前后活动的活动座,活动座的左右两侧安装有用于安装破岩装置的安装架,安装架配置有用于调整安装架水平角度以补偿轮式拖车偏移量的调平补偿机构,调平补偿机构包括调平驱动装置,主梁具有用于与轮式拖车铰接的铰接连接部,调平驱动装置一端用于与主梁连接,另一端用于与轮式支撑拖车连接,或安装架铰接在活动座上,调平驱动装置一端用于与安装架连接,另一端用于与活动座连接。该掘进机包括上述开挖装置。本发明可通过调平补偿机构带动破岩装置转动,保证破岩装置水平,保证了开挖断面形状。同时还可以主动实现破岩装置脱困。
