    摘要: The invention relates to an anchoring device wherein a positioning plate (5), intended for bearing on the ground surface, is mounted onto a hollow rod (2). The rod consecutively supports, from the positioning plate (5) to the free end (22), at least one helical force disk (6) then one helical penetration disk (8). Said anchoring device is characterized in that the rod extends after the helical penetration disk opposite the plate (5). Said anchoring device is moreover characterized in that a bit (4) is placed on the free end of said rod so that a first portion of the rod (2), capable of being screwed into at least one first ground layer, extends from the plate (5) to the helical penetration disk and moreover so that a second portion of the rod (2), capable of being anchored in a second ground layer, extends from the helical penetration disk (8) to the bit (4).

    摘要: A drilling rig includes a base and a rotation unit for drilling a hole in a mine surface. The rotation unit is moveably coupled to the base. The drilling rig further includes a cable feed device for feeding a cable bolt into the hole created by the rotation unit. The cable feed device is moveably coupled to the base and includes a pair of wheels and a transmission. The cable bolt is received between the pair of wheels. The transmission is coupled between the rotation unit and at least one of the wheels to transmit power from the rotation unit to at least one of the wheels.

    摘要: A drill rig includes a frame and a pair of cylinder rods provided laterally spaced relative to each other. The pair of cylinder rods is configured to extend and retract relative to the frame along an axial direction. The drill rig includes a carriage unit mounted to the frame. The carriage unit includes a pair of slide blocks laterally spaced relative to each other. Each of the pair of slide blocks includes an axial channel therein. The carriage unit includes a support member provided slidably within each of the axial channels. The carriage unit includes a center member coupled to and provided between the support members. The center member is configured to reinforce the support member. The carriage unit includes a slide rail longitudinally spaced relative to the support member. The drill rig includes a drilling unit slidably mounted on the slide rail.
