[0057] Combined with attachment Figure 1-Figure 7 As shown, according to some embodiments of the present application, a tunnel drilling rig and drill rod device suitable for use in a narrow space includes:

[0058] A drilling rig 1 is provided with a driving frame 2;

[0059] A power assembly 3, the power assembly 3 is arranged on the driving frame 2, a first drill rod 4 is arranged in the power assembly 3, and the power assembly 3 is used to drive the first drill rod 4 to move;

[0060] A clamping assembly 5, wherein the clamping assembly 5 is used to clamp a second drill rod 6;

[0061] The position adjustment component 7 is arranged between the drilling rig 1 and the clamping component 5. The position adjustment component 7 is used to rotate and adjust the position of the second drill rod 6 so that the axis of the second drill rod 6 is the same as that of the first drill rod 4.

[0062] Specifically, the drilling rig 1 is placed in the drilling site 10. The outline of the drilling site 10 is a wedge-shaped structure, which limits the space for loading drill rods at the rear of the drilling rig 1. The driving frame 2 is installed on the drilling rig 1, which provides a drilling platform for the power component 3. The power component 3 is installed on the driving frame 2. The power component 3 clamps the first drill rod 4 and rotates to drill into the coal seam in the drilling site 10. During the continuous drilling of the first drill rod 4, it is necessary to install a second drill rod 6 at the rear end of the first drill rod 4 to continue drilling. The position adjustment component 7 is installed at the rear of the drilling rig 1. By adjusting the position of the clamping component 5 and the second drill rod 6, the second drill rod 6 is located directly behind the first drill rod 4, and the axis of the second drill rod 6 is the same as the axis of the first drill rod 4, thereby realizing the operation of automatically loading drill rods in a narrow space. Compared with the traditional manual drill rod adding method, the entire drill rod adding process is smooth and efficient, thereby improving the efficiency of drilling operations.

[0063] The clamping assembly 5 is used to clamp and fix the second drill rod 6 to prevent the second drill rod 6 from moving during the process of adjusting the position of the second drill rod 6.

[0064] Combine Figure 3 、 Figure 4 、 Figure 5 As shown, the position adjustment component 7 includes:

[0065] A first driving unit 71 , wherein the first driving unit 71 is provided on the drilling rig 1 ;

[0066] A sliding base 72 , the sliding base 72 being disposed on the first driving portion 71 , and the first driving portion 71 being used to drive the sliding base 72 to rotate and rise and fall;

[0067] A frame rail 73 , wherein the frame rail 73 is disposed on the sliding base 72 , and the clamping assembly 5 is disposed on the frame rail 73 ;

[0068] The second driving part is provided between the sliding base 72 and the frame rail 73 , and the second driving part is used to drive the frame rail 73 to slide on the sliding base 72 .

[0069] Specifically, the power assembly 3 and the axis of the first drill rig 1 installed in the power assembly 3 are located in the center of the drill rig 1, and the first drive unit 71 is installed in the center directly behind the drill rig 1. The first drive unit 71 can drive the sliding base 72, the frame rail 73 and the clamping assembly 5 to rotate and lift, and can move the axis of the second drill rod 6 to the same as the first drill rod 4. The second drive unit can drive the frame rail 73 and the clamping assembly 5 to slide on the sliding base 72, thereby realizing the position adjustment of the second drill rod 6.

[0070] During use, the second driving unit first drives the frame rail 73 and the clamping assembly 5 to move on the sliding base 72 to the side away from the driving frame 2. At this time, at least the end of the frame rail 73 facing the driving frame 2 is flush with the end of the sliding base 72 facing the driving frame 2. Then the first driving unit 71 drives the sliding base 72 to rise to a height above the driving frame 2. At this time, the second driving unit drives the frame rail 73 to move within the sliding base 72, so that the end of the frame rail 73 away from the driving frame 2 is at least moved to a position away from the sliding base 72. One end of the drive frame 2 is level, and then the first drive unit 71 drives the sliding base 72 to rotate, and adjusts the angle of the sliding base 72 so that the frame rail 73 is located directly behind the drilling rig 1. Through the above adjustment, the frame rail 73 has been moved to the top of the drilling rig 1 before the sliding base 72 is rotated. Therefore, when the first drive unit 71 rotates the sliding base 72, the space required behind it needs to be smaller, thereby realizing the movement of the clamping assembly 5 and the second drill rod 6 to the top of the drilling rig 1 and to be located on the same vertical plane as the axis of the first drill rod 4.

[0071] Among them, the sliding base 72 is a U-shaped structure, and a limit bar is installed on the inner side of its open end. The frame rail 73 is installed inside the sliding base 72, and the first slide bar is installed at the lower part of the frame rail 73. The limit bar can limit the first slide bar, thereby making the frame rail 73 slide more stably in the sliding base 72.

[0072] Combine Figure 4 、 Figure 5 As shown, the first driving unit 71 includes:

[0073] A connecting seat 711, the connecting seat 711 is provided on the drilling rig 1, and a rotating oil cylinder 712 is provided on the connecting seat 711;

[0074] The sleeve 713 is disposed on the connecting seat 711 and includes an outer tube 7131 and an inner tube 7132 disposed within the outer tube 7131 . The rotating cylinder 712 is connected to the outer tube 7131 , and the top of the inner tube 7132 is rotatably connected to the first end of the sliding base 72 .

[0075] a first oil cylinder 714 , which is disposed on the outer tube 7131 and has an output end connected to the inner tube 7132 ;

[0076] The second oil cylinder 715 is provided on the outer tube 7131 , and an output end thereof is connected to the second end of the sliding base 72 .

[0077] Specifically, the first driving part 71 includes a connecting seat 711, a rotating cylinder 712, a sleeve 713, a first cylinder 714 and a second cylinder 715. The connecting seat 711 is fixedly connected to the middle part of the rear side of the drilling rig 1 by bolts, and the rotating cylinder 712 is fixedly installed on the connecting seat 711. When the rotating cylinder 712 rotates, it can drive the outer tube 7131 to rotate and then drive the sliding base 72 to rotate, thereby realizing the adjustment of the angle of the sliding base 72 and the components installed on the sliding base 72. At the same time, the bottom of the first oil cylinder 714 is installed on the outer tube 7131, and the output end thereof is installed on the inner tube 7132. A second oil cylinder 715 is installed between the other end of the sliding base 72 and the outer tube 7131. Therefore, the first oil cylinder 714 can drive the inner tube 7132 to move up and down relative to the outer tube 7131, and the second oil cylinder 715 can also drive the sliding base 72 to move up and down, thereby realizing the height adjustment of the sliding base 72 and the components installed on the sliding base 72. Moreover, the inner tube 7132 supports the bottom of the first end of the sliding base 72, and the second oil cylinder 715 supports the second end of the sliding base 72, thereby improving the stability of the sliding base 72 during adjustment.

[0078] The first oil cylinder 714 and the second oil cylinder 715 may also be replaced by a first electric push rod and a second electric push rod.

[0079] Combine Figure 4 、 Figure 5 As shown, the second driving unit includes:

[0080] A driving motor is provided on the sliding base 72 , and a driving hole is provided at the bottom of the sliding base 72 ;

[0081] A gear, the gear being arranged on the output end of the driving motor;

[0082] The rack is arranged at the bottom of the frame rail 73, and the gear passes through the driving hole and is engaged with the rack.

[0083] Specifically, the second driving part includes a driving motor, a gear and a rack. The driving motor is installed at the bottom of the sliding base 72 to provide power for the rotation of the gear. The gear can be engaged with the rack installed at the bottom of the frame rail 73 through the driving hole. Therefore, when the driving motor drives the gear to rotate, the cooperation of the gear and the rack can drive the frame rail 73 to move relative to the sliding base 72. The position of the frame rail 73 on the sliding base 72 can be adjusted according to usage requirements to avoid interference with obstacles when driving the second drill rod 6 to load.

[0084] Combine Figure 3 、 Figure 6As shown, a lifting assembly 8 is also included. The lifting assembly 8 is arranged between the frame rail 73 and the clamping assembly 5 and is used to adjust the height of the second drill rod 6.

[0085] The lifting assembly 8 includes:

[0086] A first fixing plate 81 , wherein the first fixing plate 81 is disposed on the frame rail 73 ;

[0087] A second fixing plate 82, the second fixing plate 82 is arranged at the bottom of the clamping assembly 5;

[0088] a swing rod 83 disposed between the first fixing plate 81 and the second fixing plate 82;

[0089] The third oil cylinder 84 is disposed between the first fixing plate 81 and the second fixing plate 82 .

[0090] Specifically, the lifting assembly 8 is installed between the frame rail 73 and the clamping assembly 5, and is used to drive the clamping assembly 5 to rise and fall on the frame rail 73, adjust the second drill rod 6 to the same height as the first drill rod 4, and load the second drill rod 6 onto the first drill rod 4.

[0091] The lifting assembly 8 includes a first fixed plate 81, a second fixed plate 82, a rocker arm 83, and a third oil cylinder 84. The first fixed plate 81 is installed on the frame rail 73, and the second fixed plate 82 is installed on the clamping assembly 5. A rocker arm 83 and a third oil cylinder 84 are installed between the first fixed plate 81 and the second fixed plate 82. Both ends of the rocker arm 83 are movably connected to the first fixed plate 81 and the second fixed plate 82. There are two rocker arms 83 to improve the stability of the rocker arm 83 during the lifting process. The third oil cylinder 84 is installed between the first fixed plate 81 and the second fixed plate 82. The third oil cylinder 84 is used to provide power to drive the first fixed plate 81 and the second fixed plate 82 to lift and lower, thereby adjusting the height of the second drill rod 6 and achieving loading alignment.

[0092] Combine Figure 3 、 Figure 6 As shown, the clamping assembly 5 includes:

[0093] A fixing block 51, wherein a fixing groove is formed in the middle of the fixing block 51;

[0094] Clamping plates 52, the clamping plates 52 are disposed in the fixing grooves, and the second drill rod 6 is located between the clamping plates 52;

[0095] The fourth oil cylinder 53 passes through the fixing block 51 and is connected to the clamping plate 52 .

[0096] Specifically, there are at least two clamping assemblies 5, and they are installed at intervals on the second fixed plate 82. The clamping assembly 5 is used to clamp and fix the second drill rod 6. The clamping assembly 5 includes a fixed block 51, a clamping plate 52 and a fourth oil cylinder 53. The fixed block 51 is installed on the second fixed plate 82, and a fixed groove is provided thereon to provide space for clamping the second drill rod 6. The clamping plate 52 is installed on both sides of the fixed groove. The fourth oil cylinder 53 is located on the outside of the fixed block 51, and its output end passes through the fixed block 51 and is connected to the clamping plate 52, which is used to drive the clamping plate 52 to move in the fixed groove, thereby clamping and fixing the second drill rod 6, improving the stability of the fixation of the second drill rod 6, and facilitating the subsequent alignment of the axes of the first drill rod 4 and the second drill rod 6 and the rod adding operation.

[0097] The fixing block 51 may be connected to the second fixing plate 82 by welding or bolts.

[0098] Combine Figure 1 、 Figure 2 、 Figure 3 As shown, the power assembly 3 includes:

[0099] A power head 31, the power head 31 is slidably disposed on the driving frame 2;

[0100] A water feeder 32 is provided on the power head 31 and is connected to the first drill rod 4 .

[0101] Specifically, the power assembly 3 comprises a power head 31 and a water feeder 32. The power head 31 slides on the drive frame 2, which provides a sliding track and stable support for the power head 31. The power head 31 integrates a drive motor, a gear transmission system, and a torque adjustment device. The drive motor outputs power, which is transmitted to the first drill rod 4 via the gear transmission system. This provides rotational torque for drilling operations, ensuring that the drill rod can quickly and stably penetrate the coal seam. The torque adjustment device can flexibly adjust the output torque according to different geological conditions and drilling requirements, preventing damage to the drill tool due to excessive torque or affecting drilling efficiency due to insufficient torque.

[0102] The water feeder 32 is mounted on the power head 31 and connected to the first drill rod 4. It can also be connected to the second drill rod 6 after being disassembled. During drilling, high-pressure flushing fluid is injected into the first drill rod 4 through the water feeder 32 and ejected through the drill bit's jet holes, cooling the drill bit, lubricating the drill rod, and carrying rock cuttings, effectively extending the service life of the drill tool and improving drilling efficiency.

[0103] Combine Figure 3 、 Figure 7 As shown, a fixing clip 9 is also included. The fixing clip 9 is arranged on the frame rail 73, and the fixing clip 9 includes:

[0104] A clamping frame 91 slidably disposed on the frame rail 73 ;

[0105] A clamping roller 92 , the clamping roller 92 being disposed on the clamping frame 91 ;

[0106] The fifth oil cylinder 93 is provided on the clamping frame 91 , and an output end thereof is connected to the clamping roller 92 .

[0107] Specifically, the clamp 9 comprises a clamping frame 91, a clamping roller 92, and a fifth hydraulic cylinder 93. The clamping frame 91 slides on the frame rail 73, which provides a guide path for its sliding. The clamping frame 91 is connected to the frame rail 73 via a sliding rail or roller structure, ensuring smooth and stable sliding of the clamping frame 91.

[0108] The clamping roller 92 is mounted on the clamping frame 91 and typically features a metal wheel core wrapped in wear-resistant rubber. The rubber outer layer increases friction with the drill rod surface, preventing the water dispenser 32 from slipping during the clamping process. Multiple clamping rollers 92 are mounted on the clamping frame 91, enabling the water dispenser 32 to be clamped from multiple directions, evenly distributing the clamping force and ensuring smooth movement. A fifth oil cylinder 93 is mounted on the clamping frame 91, its output end connected to the clamping roller 92. Driven by a hydraulic system, the fifth oil cylinder 93 adjusts the output thrust to securely secure the water dispenser 32. Once the water dispenser 32 is secured to the fixing clamp 9, it can be connected to the second drill rod 6 to supply water to the interior of the second drill rod 6.

[0109] Combine Figure 3 As shown, a sixth oil cylinder is provided between the power assembly 3 and the driving frame 2 , and the sixth oil cylinder is used to drive the power assembly 3 to move on the driving frame 2 .

[0110] Specifically, the sixth oil cylinder is connected between the driving frame 2 and the power assembly 3. When it is necessary to drive the power assembly 3 forward to drive the first drill rod 4 to perform drilling operations, the sixth oil cylinder drives the power assembly 3 to slide along the driving frame 2. In the drill rod adding link, when the power assembly 3 needs to move backward to make room for the access of the second drill rod 6 or to achieve docking, the power assembly 3 is pulled backward.

[0111] A method for using a tunnel drilling rig and a drill rod device suitable for use in a narrow space, comprising:

[0112] Step 1: Control the clamping plate 52 in the clamping assembly 5 to open, place the second drill rod 6 into the clamping plate 52, and clamp the second drill rod 6 with the clamping plate 52;

[0113] Step 2, adjust the position: the second driving part first drives the frame rail 73 and the clamping assembly 5 to move on the sliding base 72 to the side away from the driving frame 2. At this time, at least the end of the frame rail 73 facing the driving frame 2 is flush with the end of the sliding base 72 facing the driving frame 2. Then the first driving part 71 drives the sliding base 72 to rise to a height above the driving frame 2. At this time, the second driving part drives the frame rail 73 to move in the sliding base 72, and the end of the frame rail 73 away from the driving frame 2 is at least flush with the sliding base. The end of the seat 72 away from the driving frame 2 is level, and then the first driving part 71 drives the sliding base 72 to rotate, and adjusts the angle of the sliding base 72 so that the frame rail 73 is located directly behind the drilling rig 1. Through the above adjustment, the frame rail 73 has been moved to the top of the drilling rig 1 before the sliding base 72 is rotated. Therefore, when the first driving part 71 rotates the sliding base 72, the space required behind it needs to be smaller, thereby achieving the second drill rod 6 being moved to the top of the drilling rig 1 and being located on the same vertical plane as the axis of the first drill rod 4;

[0114] Step 3. Adjust the height of the second drill rod 6 through the lifting assembly 8 so that the second drill rod 6 has the same axis as the first drill rod 4, that is, the second drill rod 6 is located directly behind the first drill rod 4, remove the water feeder 32 from the power head 31, and install it in the fixing clamp 9. The second driving part drives the frame rail 73 to slide on the sliding base 72, and loads the second drill rod 6 to the rear side of the first drill rod 4 to realize the loading of the drill rod.
