The other side of the connecting rod 20 is rotatably connected to the surface of the hydraulic base 22 via the tenth rotating shaft 21. The top of the hydraulic base 22 is rotatably connected to the surface of the adjusting arm 13 via a rotating shaft assembly. In this design, the rock drill frame 2 constitutes the main body of the rock drill, and a large number of related components are installed in the main body of the rock drill. Since these are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution.
[0022] Preferably, a "U"-shaped slide is provided on one side of the rock drill frame 2, the shape and size of which are adapted to the protrusions on the surface of the moving block 1.
[0023] In practical use, the sliding block 1 connected to one side of the rock drill frame 2 is used to adjust the angle and orientation of the sliding block 1 under the extension and retraction of the connected first hydraulic cylinder 4 and second hydraulic cylinder 7.
[0024] Preferably, the first rotating shaft 3, the first hydraulic cylinder 4, the second rotating shaft 5, the third rotating shaft 6, and the second hydraulic cylinder 7 form a rotary connection structure.
[0025] In practical use, when the first hydraulic cylinder 4 and the second hydraulic cylinder 7 extend and retract simultaneously, the first rotating shaft 3 and the third rotating shaft 6 and the second rotating shaft 5 connected to their two ends can rotate on the connected rock drill frame 2, thereby facilitating stable support and adjustment of the angle of the rock drill frame 2.
[0026] Preferably, a rectangular groove is provided on one side of the adjusting arm 13, the shape and size of which are adapted to the second connecting arm 10.
[0027] In practical use, the second connecting arm 10, which is easily rotated and connected by the groove on one side of the adjusting arm 13, can rotate on the adjusting arm 13 to adjust the angle under the action of the connected sixth rotating shaft 14.
[0028] Preferably, the adjustment frame 18 has a "V" shaped integrated structure.
[0029] In practical use, the rotating shaft assembly and connecting rod 20 connected to both sides of the adjusting frame 18 are respectively connected to its two sides, so that the adjusting frame 18, which is rotatably connected to the hydraulic base 22, can be stably supported and rotated for adjustment.
[0030] Preferably, the second connecting arm 10, the adjusting arm 13, and the sixth rotating shaft 14 form a rotary connection structure.

[0032] Working principle: When using the drill bit of the rock drill frame 2 to process the rock wall or tunnel surface to be drilled, the hydraulic base 22 is installed on the transfer device by bolts and other components. Then, the hydraulic base 22 is transported to the area where rock drilling is required. When it is necessary to adjust the position and height of the moving block 1, the power switch connected to the outside of the hydraulic base 22 is activated according to the set parameters. This causes the telescopic component rotatably connected to the adjusting frame 18 at its top telescopic end to rotate the adjusting frame 18. At this time, the adjusting frame 18 rotatably connected to the hydraulic base 22 can rotate on top of the hydraulic base 22. During its rotation, the connecting rod 20 rotatably connected between the hydraulic base 22 and the adjusting frame 18 can rotate through the ninth rotating shaft 1 connected at both ends. The first hydraulic cylinder 9 rotates under the action of the tenth rotating shaft 21, thereby providing stable support for the adjustment frame 18 for rotation adjustment. At the same time, the fourth hydraulic cylinder 16 rotatably connected to the adjustment frame 18 starts to extend and retract, which allows the second connecting arm 10 rotatably connected to the other side to extend, retract and rotate under the action of the connected fourth hydraulic cylinder 16 and the seventh rotating shaft 15, thereby adjusting the height and angle of the rock drill frame 2. In addition, the extension and retraction end of the third hydraulic cylinder 11 connected to the connecting ear of the rock drill frame 2 can extend and retract together. At the same time, when the second hydraulic cylinder 7 and the first hydraulic cylinder 4 connected to the first connecting arm 9 extend and retract, they can drive the connected moving block 1 to move on the rock drill frame 2, thereby adjusting the position of the rock drill frame 2 to meet the rock drilling needs of different environments and positions.
