Description

Technical Field

[0001] The utility model relates to the technical field of feed frames, specifically referring to the feed frame of a tunnel drill rig. Background Art

[0002] A tunnel drill rig is a device specifically used for drilling in underground roadways (tunnels), mainly used for the construction of other projects such as deep geological exploration, gas drainage, water injection and drainage, and ventilation in roadways (tunnels).

[0003] During processing and use, the tunnel drill rig has relatively high requirements for the volume of the roadway and requires a separate excavation and placement site to accommodate the installation and placement of the drill rig.

[0004] Among them, in order to adapt to the drilling operation of the front and back push and pull movement of the tunnel drill rig head during the drilling process, a feed frame is generally required for cooperation. The head is connected by screws and sits on the support plate, and the support plate sits on the feed frame for sliding. The feed frames in the prior art are often welded and spliced by simple plates, which are not easy to discharge drilling waste and have poor adjustability. Content of the Utility Model
