Example 7

On the basis of embodiment 5, a sliding mechanism is added, and the sliding mechanism comprises a rail mechanism 1 and a moving seat mechanism 2. The large arm rotary table 3 of the large arm mechanism is arranged on the movable seat mechanism 2, the movable seat mechanism 2 is arranged on the track mechanism 1, and the large arm rotary table 3 can be driven to move in the longitudinal direction of the track mechanism 1. The large arm mechanism, the bearing template mechanism 9, the spray head assembly 8, the fine adjustment mechanism and other related mechanisms and assemblies on the large arm mechanism can move along the longitudinal direction of the excavated rock surface along with the large arm mechanism, and a mold cavity formed between the template mechanism 8 and the rock surface can be adjusted along the longitudinal direction of the rock surface. For example, in the early-stage tunnel supporting die spraying, continuous multi-section rock face die spraying can be carried out under the condition that a carrier mechanism (such as a trolley) is moved by a single time, the defect that single-section rock face die spraying can only be carried out by single-section moving is avoided, and the construction efficiency of die spraying is greatly improved.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
