[0056] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0057] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the utility model provides a rock drilling assembly, including: a mounting seat 1, an angle adjustment assembly 2, a mounting assembly 3, a rotating assembly 4, a slide rail assembly 5, a mobile trolley 6 and a rock drilling mechanism 7. The mounting seat 1 is rotatably mounted on the end of the lifting arm of the trolley that drives the rock drilling assembly to move (it can be understood that the mobile trolley is similar to the base of an excavator and the telescopic arm of an excavator.). One end of the angle adjustment assembly 2 is hinged to the lifting arm of the trolley that drives the rock drilling assembly to move, and the other end of the angle adjustment assembly 2 is hinged to the mounting seat 1. The mounting assembly 3 is mounted on the mounting seat 1. The rotating assembly 4 is mounted on the top of the mounting assembly 3. The slide rail assembly 5 is mounted on the rotating assembly 4. The mobile trolley 6 is mounted on the slide rail assembly 5, and the mobile trolley 6 can reciprocate on the slide rail assembly 5. The rock drilling mechanism 7 is mounted on the mobile trolley 6, and the construction surface is constructed under the drive of the mobile trolley 6.

[0058] When constructing the side wall of the tunnel, the trolley is moved to the designated position, and then the height is adjusted by the telescopic arm on the trolley. During the adjustment process, the angle of the rock drilling mechanism 7 is adjusted by the angle adjustment component 2. Since the side wall of the tunnel is an arc-shaped structure, in order to facilitate the angle adjustment during the construction process, the rock drilling assembly 4 is adjusted, and after the adjustment, the rock drilling assembly installed on the slide rail assembly 5 better fits the arc structure of the tunnel. During construction, the mobile trolley 6 drives the rock drilling mechanism 7 to move toward one side of the construction surface, and the rock drilling mechanism 7 completes the construction of the construction surface.

[0059] More specifically, if Figure 1 and Figure 2 As shown, the rock drilling mechanism 7 includes: a rotary mechanism 71, a tool holder 72, a plurality of pneumatic rock drills 73 and a tool 74. The rotary mechanism 71 is mounted on the top of the mobile vehicle 6. The tool holder 72 is mounted on the movable end of the rotary mechanism 71. A plurality of pneumatic rock drills 73 are mounted side by side on the tool holder 72, and the movable ends of the pneumatic rock drills 73 are arranged toward the construction surface. A tool 74 is arranged on the movable end of each pneumatic rock drill 73.

[0060] When in use, the rotary mechanism 71 drives the tool holder 72 to rotate, and during the rotation process, the tool 74 installed on the starting rock drill is more closely matched with the processed arc surface. After the adjustment is completed, the pneumatic rock drill 73 drives the tool 74 to perform construction. During the construction process, since each pneumatic rock drill 73 drives the tool 74 to move independently, the impact is divided, so that the back force acting on the base is small.

[0061] In one embodiment, if Figure 1 and Figure 2 As shown, the angle adjustment assembly 2 includes: a linear drive mechanism 21, a first connecting rod 22 and a second connecting rod 23. One end of the linear drive mechanism 21 is hinged to an end of the lifting arm of the trolley that drives the rock drilling assembly to move away from the mounting seat 1, and the other end is arranged toward the mounting seat 1. One end of the first connecting rod 22 is hinged to the other end of the linear drive mechanism 21, and the other end of the first connecting rod 22 is hinged to an end of the lifting arm of the trolley that drives the rock drilling assembly to move close to the mounting seat 1. One end of the second connecting rod 23 is hinged at the hinge of the first connecting rod 22 and the linear drive mechanism 21, and the other end of the second connecting rod 23 is hinged to the mounting seat 1.

[0062] When in use, the linear drive mechanism 21 is telescopically driven to drive the first connecting rod 22 and the second connecting rod 23 to rotate around their hinges, and the first connecting rod 22 and the second connecting rod 23 rotate around the hinges at the same time, driving the mounting seat 1 and the structural member mounted on the mounting seat 1 to rotate during the rotation process.

[0063] In one embodiment, if Figure 1 and Figure 2As shown, the slide rail assembly 5 includes: a rail body 51, a connecting plate 53 and a limiting plate 54. A slide groove 52 is provided on the opposite side walls of the rail body 51, and the moving trolley 6 is installed in the slide groove 52. The connecting plate 53 is installed at the bottom of the rail body 51, and the connecting plate 53 is connected to the rotating assembly 4. The limiting plate 54 is installed at one end of the rail body 51 away from the construction surface.

[0064] During use, in order to facilitate the installation of the track body 51, a connecting plate 53 is provided below the track body 51, and the connecting plate 53 is connected to the movable end of the rotating assembly 4. The rotating assembly 4 drives the track body 51 to rotate during use, so that the angle of the structural parts installed on the track body 51 changes. Slide grooves 52 are provided on the opposite side walls of the track body 51, and the mobile trolley 6 is installed in the slide grooves 52 of the track body 51. The mobile trolley 6 is limited by the slide grooves 52 on the track body 51 to prevent it from deviating during movement. The limiting plate 54 is provided at one end of the track body 51 away from the construction surface to prevent the mobile trolley 6 from falling off the track body 51 during installation.

[0065] In one embodiment, if Figure 1 and Figure 2 As shown, the mobile trolley 6 comprises: a trolley body 61, a moving wheel 62 and a reciprocating mechanism 63. A mounting opening is provided at the bottom of the trolley body 61, and the trolley body 61 is clamped on the slide rail assembly 5 through the mounting opening. The moving wheels 62 are mounted on opposite sides of the mounting opening, and the moving wheels 62 slide in the slide groove 52 of the track body 51 after being mounted. The reciprocating mechanism 63 is mounted at one end of the slide rail assembly 5 away from the slide rail assembly 5 toward the construction surface, and the movable end of the reciprocating mechanism 63 is connected to the trolley body 61.

[0066] When in use, the reciprocating mechanism 63 drives the trolley body 61 to slide on the slide rail assembly 5. During the sliding process, the moving wheel 62 installed on the trolley body 61 slides in the slide groove 52 of the track body 51. Since the moving wheel 62 slides in the slide groove 52, the trolley body 61 will not deviate when moving, thereby improving the stability of the rock drilling assembly when in use.

[0067] In one embodiment, the mounting assembly 3 includes: a rotating seat 31, a first driving member 32, a mounting frame 33 and a second driving member 34. The rotating seat 31 is rotatably mounted on the mounting seat 1, and the rotation axis of the rotating seat 31 is perpendicular to the rotation axis of the mounting seat 1. One end of the first driving member 32 is hinged to the mounting seat 1, and the other end is hinged to the rotating seat 31, and the extension and contraction of the first driving member 32 drives the rotating seat 31 to rotate around the rotation point of the mounting seat 1. One end of the mounting frame 33 is rotatably connected to the rotating seat 31, and the rotation direction of the mounting frame 33 is the same as the rotation direction of the mounting seat 1. One end of the second driving member 34 is hinged to the rotating seat 31, and the other end is hinged to an end of the mounting frame 33 away from the rotating seat 31.

[0068] Since the side wall of the tunnel is an arc-shaped structure, in order to facilitate angle adjustment during construction, a first driving member 32, a second driving member 34 and a rotating assembly 4 are provided. After adjustment, the rock drilling assembly installed on the slide rail assembly 5 better fits the arc-shaped structure of the tunnel.

[0069] In one embodiment, in order to prevent the pneumatic rock drill 73 from contacting the inner wall of the tunnel during the rock drilling process and affecting the feeding of the pneumatic rock drill 73, the highest surface of the teeth of the tool 74 is higher than the height of the highest position of the pneumatic rock drill 73 after installation.

[0070] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
