Disclosed is a self-moving tunnel support canopy, comprising a front arch frame (1), a rear arch frame (2), front moving jacks (3) and support jacks (4). The front arch frame (1) comprises more than three front longitudinal beams (10) and more than three front arch beams (11), with all the front longitudinal beams (10) placed longitudinally along the arched upper surface of the front arch beams (11), each front longitudinal beam (10) connected to all the front arch beams (11), and the support jacks (4) being provided below the front arch frame (1). The rear arch frame (2) comprises more than three rear longitudinal beams (20) and more than three rear arch beams (21), with all the rear longitudinal beams (20) placed longitudinally along the arched upper surface of the rear arch beams (21), each rear longitudinal beam (20) connected to all the rear arch beams (21), and the support jacks (4) being provided below the rear arch frame (2). The front longitudinal beams (10) are spaced apart from the rear longitudinal beams (20), and the front arch beams (11) are spaced at a distance from the adjacent rear arch beams (21) at the front. One end of the front moving jacks (3) is connected to the front arch frame (1) and the other end of the front moving jacks (3) is connected to the rear arch frame (2). The front arch beams (11) and the rear arch beams (21) are all arched beams. Using the present self-moving tunnel support canopy saves time and effort, and is safe and reliable. |
