[0002] Crawler-type fully automatic drilling rigs are increasingly used in underground drilling operations in coal mines. Usually, a mounting platform is set on the crawler vehicle for installing the drill rod box, manipulator and drilling device. When drilling: the drill rod is transported from the drill rod box to the drilling device by the manipulator; when unloading the drill rod, the drill rod is transported from the drilling device back to the drill rod box.

[0003] The existing drilling system has the following disadvantages:

[0004] 1. The connection seats with many weldments on the rotary platform cause large deformation of the platform.

[0005] 2. The drill pipe box is welded together with welded parts. Because there are many welds, the shape of the box cannot be guaranteed after welding.

[0006] 3. The width of the drill rod box is fixed, and the drill rod cannot be centered, so the manipulator grabs different drill rods, not all of which are in the center of the drill rod.

[0007] 4. When the drilling frame is arranged on the outside of the column, when the arrangement position of the drilling frame is changed according to the site needs, the drilling frame needs to be disassembled and reinstalled, which is a large workload. Summary of the invention
