Claims

[Scope of utility model registration request]

H steel rails of the required unit length are connected in the vertical direction on the sloping bedrock surface using horizontal pins, and two H steel rails that match the sloped bedrock surface are laid.
A bridge type trestle that can run on the rail of the strip is provided, and the end of the traveling bogie of the bridge type trestle is suspended and supported by the rope of a hoist installed at the top of the bedrock so that it can run up and down, and furthermore, the bridge The girder part of the bridge-shaped pedestal is supported on a leg frame equipped with an inclination adjustment mechanism that rotates the lower part in a vertical plane about the fulcrum on the upper bogie of the bridge-shaped pedestal, and a hole is bored above the girder part so that it can be moved laterally. An automatic drilling device for sloped rock surfaces characterized by being equipped with a machine.
