[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0040] The frame 11 is the body frame of the anchoring and digging machine, and the frame 1 can be formed by welding profiles. Figure 1 and Figure 2 As shown, the frame 11 may be arranged to extend generally along the front-to-back direction.

[0041] The top support assembly 2 can be fixed above the frame 1 along the up and down direction. The top support assembly 2 has a minimum lowering height and a maximum lifting height. At the lowest lowering height, the top support assembly 2 is suitable for advancing the anchor and digger machine along the extension direction of the coal seam to stabilize the body of the anchor and digger machine. At the highest lifting height, the top support assembly 2 is suitable for supporting the roof of the tunnel.

[0042] Specifically, Figures 2 to 4 As shown, the top support assembly 2 is arranged above the rack 1, and the top support assembly 2 may include a lifting member 21, a supporting member 22 and a stabilizing member 23; wherein the rack 1 extends in the front-to-back direction, and the lower end of the lifting member 21 is connected to the rear end of the rack 1. For example, the lower end of the lifting member 21 may be connected to the front end of the rack 1 through a fixing seat 212, wherein the lower end of the lifting member 21 is fixed in the fixing seat 212, and the fixing seat 212 is fixedly connected to the top of the rack 1 through bolts, and the top end of the lifting member 21 can be adjusted relative to the height of the rack 1 by the lifting member 21 itself. The lower end of the stabilizing member 23 is connected to the front end of the bottom of the rack 1, for example, the lower end of the stabilizing member 23 may be connected to the front end of the rack 1 through a fixing seat 212, wherein the lower end of the stabilizing member 23 is fixedly connected to the rack 1, and the top end of the stabilizing member 23 can be adjusted relative to the height of the rack 1 by the lifting member 21 itself.

[0043] It should be noted that the upper end of the lifting member 21 and the upper end of the stabilizing member 23 are respectively arranged at the rear end and the front end of the bottom of the supporting member 22, for example Figure 3 As shown, the upper end of the lifting member 21 and the upper end of the stabilizing member 23 are respectively connected to the rear end and the front end of the bottom of the supporting member 22 through axle pins. The lifting and lowering of the lifting member 21 and the stabilizing member 23 are synchronized, and the height of the supporting member 22 relative to the frame 1 is adjusted by the lifting and lowering of the lifting member 21 and the stabilizing member 23, so that it can be used to support the top plate of the tunnel.

[0044] Specifically, Figure 2 The side support assembly 3 is located on the side of the frame 1, facing the side wall of the tunnel for realizing side support. The side support assembly 3 is fixed to the right side of the frame 1, and the side support assembly 3 is retractable, so as to support between the frame 1 and the side wall of the tunnel to realize side support.

[0045] In some embodiments, the support member 22 includes a ceiling 221, an inner ceiling 222 and an outer ceiling 223; the inner ceiling 222 is movably connected to one side of the ceiling 221, away from the side wall of the tunnel; the outer ceiling 223 is movably connected to the other side of the ceiling 221, facing the side wall of the tunnel; the lifting member 21 and the stabilizing member 23 are respectively located at the two ends of the front and rear directions of the bottom of the ceiling 221.
