[0024] A pin 6 is rotatably mounted on one side of the circular plate 4. A connecting body 7 is fixedly mounted on one side of the pin 6, and a drilling mast 8 is detachably mounted on one side of the connecting body 7.

[0025] A pushing component 9 is installed on one side of the circular plate 4 and is used to push the connecting body 7 to rotate slightly left and right to adjust the angle. The pushing component 9 includes a hydraulic cylinder 91 rotatably installed on one side of the circular plate 4, and the telescopic end of the hydraulic cylinder 91 is rotatably connected to the connecting body 7. A rotating shaft 10 is fixedly installed on one side of the connecting body 7 at a position off the center line, and the rotating shaft 10 is rotatably inserted into the telescopic end of the hydraulic cylinder 91.

[0026] During rotary drilling rig construction, to achieve precise mast angle adjustment and ensure its stability, this device is installed on top of the drilling rig via a base 1, providing a stable support foundation for the entire device. The boom 2 is installed on top of the base 1, and the two are connected by a shock-absorbing component 3. The shock-absorbing component 3 can effectively absorb the vibration generated during drilling operations, preventing damage to the mast connection structure due to large-scale vibrations, thereby avoiding damage to the mast due to prolonged vibration, extending its service life, and reducing equipment maintenance costs.

[0027] One side of the circular plate 4 is rotatably installed on one side of the movable arm 2, and a driving assembly 5 on the movable arm 2 is used to drive the circular plate 4 to rotate forward and backward. When it is necessary to adjust the angle of the drilling rig mast 8, the driving assembly 5 is started to drive the circular plate 4 to rotate, and then drive the pin shaft 6, the connecting body 7 and the drilling rig mast 8 to rotate as a whole, so as to realize large-angle adjustment of the drilling rig mast 8, so as to meet the basic requirements of the angle of the mast in different construction scenes. In addition, in order to realize small-angle adjustment of the drilling rig mast 8, a pushing piece 9 is installed on one side of the circular plate 4. The pushing piece 9 comprises an oil cylinder 91 which is rotatably installed on one side of the circular plate 4, and the telescopic end of the oil cylinder 91 is rotatably connected with the connecting body 7.
