[0027] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0028] Please refer to Figures 1 to 3 The present invention provides a rock drilling arm, which is used to drill blast holes and anchor holes. The blast holes are parallel to the axis of the inclined shaft, and the anchor holes are perpendicular to the shaft wall. The rock drilling arm 70 includes a swing seat 71, a boom assembly 73, a rotating arm assembly 75, and a rock drilling propulsion device 77. The bottom of the boom assembly 73 is rotatably connected to the swing seat 71, and the end is rotatably connected to the rotating arm assembly 75. The boom assembly 73 controls the pitch of the rotating arm assembly 75 to different angles. The rotating arm assembly 75 rotates to different angles to drive the rock drilling propulsion device 77 to rotate to different angles for drilling holes in the face and shaft wall of the inclined shaft.

[0029] like Figure 4 As shown, the swing seat 71 is fixed on the trolley frame 10, and the trolley frame 10 moves back and forth along the track installed in the inclined shaft. The entire drilling arm 70 can be moved to different positions for operation under the drive of the moving trolley. Figure 2As shown, the swing seat 71 includes a swing base 711 and a swing cylinder 713 integrally mounted on the swing base 711. The bottom of the boom assembly 73 is hinged to the swing base 711. The swing cylinder 713 controls the left and right movement of the swing base 711, allowing the boom assembly 73 to change its drilling position as it moves left and right. This provides a flexible structure and a wider range of operation.

[0030] like Figure 3 As shown, specifically, one end of the swing cylinder 713 is hinged to the swing base 711 through a connecting bracket 712 to achieve the left and right swinging movement of the swing base 711.

[0031] Specifically, the boom assembly 73 includes a boom 731, a boom pitch cylinder 733, and a support base 735. One end of the boom pitch cylinder 733 is hinged to the swing base 71, and the other end is hinged to the boom 731. The boom 731 and the rotating platform base 751 are rotatably connected via the support base 735. The boom pitch cylinder 733 controls the amplitude of the boom 731, thereby achieving the pitching movement of the entire boom. The boom assembly 73, combined with the rotating arm assembly 75, can achieve pitching and rotation angles, thereby simultaneously realizing the functions of drilling blasting holes and anchor holes. Among them, the boom 731 is composed of multiple sections of telescopic booms to achieve length changes. The inner diameters of the multiple sections of the booms are different, and the multiple sections of the telescopic booms are integrated to achieve length changes, thereby flexibly changing the length of the boom. This telescopic structure is a conventional technology and will not be described in detail in this embodiment.

[0032] Specifically, the support base 735 is L-shaped to facilitate the connection between components. Specifically, a portion of the support base is mounted on the arm 731 and the rotating platform base 751, and the other portion is bent outward to extend to connect to other positionable components.

[0033] Furthermore, the bottom of the boom 731 is also fixedly connected to a mounting support 737, and the boom pitch cylinder 733 and the swing seat 71 are both hinged on the mounting support 737. Installation through the mounting support 737 can improve the stability of the structure and make the structure more reasonable.

[0034] Specifically, the rotating arm assembly 75 includes a rotating platform seat 751, a slewing mechanism 753, a rotating arm 755, a platform seat pitch cylinder 757, a rotating arm swing cylinder 758 and a rotating arm pitch cylinder 759. The rotating platform seat 751 is hinged to the boom assembly 73, and the slewing mechanism 753 is assembled at the bottom of the rotating platform seat 751. One end of the rotating arm 755 is hinged to the bracket at the bottom of the slewing mechanism 753, and the other end is connected to the rotating arm swing cylinder 758. One end of the platform seat pitch cylinder 757 is hinged to the support seat 735 of the boom assembly, and the other end is hinged to the rotating platform seat 751. The rock drilling propulsion device 77 is connected to the rotating arm swing cylinder 758. One end of the rotating arm pitch cylinder 759 is hinged to the bottom of the rotating platform seat 751, and the other end is hinged to the rotating arm 755. The rotating arm 755 is extended and retracted to control the operational range of the rock drilling propulsion device 77. The rotating arm pitch cylinder 759 is extended and retracted to control the pitch angle of the rotating arm 755. Simultaneously, the platform base pitch cylinder 757 is extended and retracted to adjust the pitch angle of the rotating platform base 751, thereby controlling the pitch angle and rotation angle of the rock drilling propulsion device 77. The slewing mechanism 753 is controlled to rotate 360°. The slewing mechanism 753 drives the rotating arm 755 and the rotating arm pitch cylinder 759 to rotate, thereby driving the rock drilling propulsion device connected to the rotating arm 755 to rotate 360°. The rock drilling propulsion device 77 has an operational range with the boom assembly 73 and the rotating arm assembly 75 as the radius. This greatly increases the operating range of the rock drilling propulsion device 77 in the inclined shaft, allowing for wide-range operations without moving the entire drilling arm, effectively improving work efficiency.

[0035] The rotating arm 755 is comprised of multiple, retractable arms that can be adjusted in length. These arms have varying inner diameters, and the multiple retractable arms are telescopically integrated to allow for flexible length adjustment. This retractable structure is well known in the art and will not be further described in this embodiment.

[0036] Specifically, in this embodiment, the slewing mechanism 753 is a turntable. The turntable is an operating platform that performs controlled slewing motion, and the slewing arm assembly 75 rotates 360° driven by the turntable. Furthermore, the slewing mechanism 753 is composed of a slewing bearing and a slewing drive, wherein the slewing drive comprises a reducer and a motor.

[0037] like Figure 2As shown, specifically, the rock drilling propulsion device 77 includes a connecting seat 771, a propulsion pitch cylinder 773, a propulsion swing cylinder 775 and a rock drilling mechanism 777. The propulsion swing cylinder 775 is connected to the rotating arm assembly 75. One end of the connecting seat 771 is fixedly connected to the propulsion swing cylinder 775, and the other end is hinged to the rock drilling mechanism 777. One end of the propulsion pitch cylinder 773 is hinged to the connecting seat 771, and the other end is hinged to the rock drilling mechanism 777.

[0038] like Figure 4 Specifically, when the trolley is traveling or performing other operations, the boom assembly 73 and the rotary arm assembly 75 are fully retracted, and the drilling arm is retracted by operating the pitch cylinders and the swing cylinders, without affecting other boom operations or trolley travel.

[0039] like Figure 5 The figure shows a drilling arm in a blasthole drilling position. By adjusting the length of the swing cylinder 713, boom pitch cylinder 733, and boom 731, while also adjusting the length of the platform pitch cylinder 757 and the movement of the slewing mechanism 753, the length of the rotating arm pitch cylinder 759 and rotating arm 755 are adjusted, and the rotating arm swing cylinder 758, the propulsion swing cylinder 775, and the propulsion pitch cylinder 773 are operated, the rock drilling propulsion device 77 is aligned parallel to the axis of the inclined shaft. The rock drilling propulsion device 77 is operated to drill the drill rod into the blasthole. After completing the drilling of one blasthole, the various cylinders or the swing cylinder 713 are operated to move the drill rod to the next blasthole location for drilling.

[0040] like Figure 6 As shown in FIG, the figure shows another posture of the rock drilling arm drilling a blasthole; after the rotary mechanism 753 rotates the angle, the adjustment method of the rock drilling arm is the same as the above-mentioned method of drilling a blasthole.

[0041] like Figure 7 and Figure 8 The figure shows two different positions of the rock drilling arm during anchor drilling. By adjusting the arm's position so that the slewing drive is positioned perpendicular to the shaft axis, the hydraulic cylinders and the swing cylinder are operated to align the rock drilling propulsion device 77 perpendicularly with the rock wall. The rock drilling propulsion device 77 is then operated to drill the drill rod into the hole. After completing one anchor hole, the next anchor hole can be drilled simply by rotating the slewing mechanism 753.

[0042] Furthermore, the actions and functions of each cylinder are as follows: by operating the swing cylinder 713, the entire arm assembly can be swung left and right, and by operating the boom pitch cylinder 733, the entire arm can be pitched. The platform seat pitch cylinder 757 can adjust the angle of the rotating platform seat 751, and the rotating arm pitch cylinder 759 can adjust the posture of the rotating arm assembly 75. The rotating arm swing cylinder 758 can make its front end part rotate within a range of 360°, and the thrust swing cylinder can make its front end part swing within a range of 360° as a whole. The thrust pitch cylinder 773 can make the entire rock drilling propulsion device 77 pitch as a whole. The entire rock drilling arm structure is flexible and has a wide range of operability.

[0043] The present invention also provides an underground operation trolley, which includes the above-mentioned rock drilling arm 70 and a trolley frame 10, on which the rock drilling arm is mounted. A track is installed in the well, and the trolley frame 10 runs along the track, carrying the rock drilling arm 70 to operate at different positions in the well.

[0044] The rock drilling boom provided by the present embodiment controls the operating range of the rock drilling propulsion device 77 by extending and retracting the rotating arm 755. The pitch angle of the rotating arm 755 is controlled by extending and retracting the rotating arm pitch cylinder 759. Simultaneously, the pitch angle of the rotating platform 751 is adjusted by the platform pitch cylinder 757, thereby controlling the pitch and rotation angles of the rock drilling propulsion device 77. The slewing mechanism 753 is controlled to rotate 360°, driving the rotating arm 755 and the rotating arm pitch cylinder 759 to rotate, thereby driving the rock drilling propulsion device connected to the rotating arm 755 to rotate 360°. Furthermore, the rock drilling propulsion device 77 has an operating range within a radius of the boom assembly 73 and the rotating arm assembly 75. This significantly increases the operating range of the rock drilling propulsion device 77 in deviated wells, enabling both blasthole drilling and anchor bolt drilling, achieving mechanized drilling and enabling wide-area operations without moving the entire work platform, effectively improving work efficiency.

[0045] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
