[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0025] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0026] Example 1: As Figure 1 , Figure 2As shown, the present invention provides a traveling operation device for a bidirectional rotary drilling rig in a mine, comprising: The walking base 1 is used for walking on the mine road surface, and the drilling rig through hole 4 is set in the center of the walking base 1; 2. Two-way rotary drilling rig; Support frame 3 is mounted on the traveling base 1 and is used to support the upper part of the bidirectional rotary drilling rig 2; An auxiliary positioning unit is set on the traveling base 1 and surrounds the drilling rig through hole 4, and is used to position the bidirectional rotary drilling rig 2 to the center.

[0027] The bidirectional rotary drilling rig 2 is a pneumatic anchor drilling rig. The bidirectional rotary drilling rig 2 is equipped with a switching handle, which can switch between left and right rotary drilling operations.

[0028] The support frame 3 is connected to the upper part of the traveling base 1 via a column. The support frame 3 is set as a ring frame. The bidirectional rotary drilling rig 2 is hung inside the support frame 3 and extends into the drilling rig through hole 4.

[0029] The working principle and beneficial effects of the above technical solution are as follows: This invention provides a walking operation device for a bidirectional rotary drilling rig in a mine. In use, the bidirectional rotary drilling rig 2 is hoisted above a support frame 3, then lowered and anchored at the center of the support frame 3, with the bottom of the bidirectional rotary drilling rig 2 positioned above the drilling through-hole 4. After moving to the working position, the bidirectional rotary drilling rig 2 is activated, causing its bottom air leg to extend downwards and insert its bottom conical head into the ground. It then continues to extend upwards. After insertion, an auxiliary positioning unit positions the bottom of the air leg of the bidirectional rotary drilling rig 2 to the center of the drilling through-hole 4, maintaining the bidirectional rotary drilling rig 2 in a neutral position. During the extension of the air leg, a certain distance is maintained between the air leg and the drilling through-hole 4 and the support frame 3.

[0030] Through the above structural design, the present invention has the following beneficial effects: Based on the existing pneumatic anchor drilling rig auxiliary vehicle, improvements were made by setting up a tracked walking base to adapt to the uneven road surface in the mine, improve the stability of the drilling rig's movement, and achieve rapid and energy-saving operation in the mine.

[0031] The bidirectional rotary drilling rig 2 is configured as a pneumatic anchor drilling rig with left and right rotation, which facilitates switching between left and right rotation during anchor drilling, improves work efficiency, and achieves energy saving.

[0032] The bidirectional rotary drilling rig 2 is attached to the traveling base 1, which makes it easy to move to the working position. The machine body does not need to be disassembled during operation, which improves the convenience of operation.

[0033] During drilling operations, the bidirectional rotary drilling rig 2 is positioned in the center by the auxiliary positioning unit to prevent collisions between the drilling rig and the device during lifting, hoisting, and operation, thus improving the operational safety of the device. The auxiliary positioning unit is not activated during drilling rig movement; the bidirectional rotary drilling rig 2 is attached to the device, avoiding prolonged stress on the bottom of the drilling rig and the auxiliary positioning unit, thereby extending the service life of the auxiliary positioning unit.

[0034] Example 2: Figure 2 , Figure 3 As shown, based on the above embodiment 1, the auxiliary positioning unit includes: Support plate 11 is installed at the bottom of the air leg of the bidirectional rotary drilling rig 2; Auxiliary positioning plates 12, multiple auxiliary positioning plates 12 are evenly installed in the circumferential direction of the support plate 11; Telescopic cylinder 13, multiple telescopic cylinders 13 are vertically installed on the top surface of the walking base 1; The sliding positioning frame 14 is installed on the telescopic end of the telescopic cylinder 13, and the end is connected to the positioning roller 15.

[0035] The working principle and beneficial effects of the above technical solution are as follows: When the bidirectional rotary drilling rig 2 is attached to the support frame 3, the direction of the bidirectional rotary drilling rig 2 is manually adjusted so that the auxiliary positioning plate 12 corresponds to the direction of the sliding positioning frame 14, ensuring that the two can contact each other during the positioning process. During positioning, the telescopic cylinder 13 is activated to drive the sliding positioning frame 14 to move, pressing the positioning roller 15 against the outside of the inclined auxiliary positioning plate 12, pushing the offset auxiliary positioning plate 12 towards the center, so that the bottom of the air leg of the bidirectional rotary drilling rig 2 is located at the center of the drilling through hole 4. Through the above structural design, a combination structure of support plate 11 and auxiliary positioning plate 12 is set at the bottom of the air leg of the bidirectional rotary drilling rig 2. The auxiliary positioning plate 12 provides a sufficiently large pressing surface so that the positioning roller 15 can press the support plate 11 back to the center position.

[0036] Example 3: As Figure 5 As shown, based on the above embodiment 2, the positioning roller 15 is configured to rotate in one direction; After the bidirectional rotary drilling rig 2 is inserted into the ground, the telescopic cylinder 13 drives the end of the sliding positioning frame 14 to descend, causing the positioning roller 15 to roll downward and abut against the side of the auxiliary positioning plate 12. When the bidirectional rotary drilling rig 2 is pulled out, the telescopic cylinder 13 drives the end of the sliding positioning frame 14 to rise, moving the positioning roller 15 upward and pushing out the auxiliary positioning plate 12.

[0037] The working principle and beneficial effects of the above technical solution are as follows: The positioning roller 15 is configured to rotate in one direction only, that is, the positioning roller 15 can only rotate downwards and upward rotation is restricted. This can be achieved by setting a ratchet structure on the rotation axis of the positioning roller 15.

[0038] After the bidirectional rotary drilling rig 2 is inserted into the ground, the telescopic cylinder 13 drives the end of the sliding positioning frame 14 to descend, causing the positioning rollers 15 to roll downwards. The positioning rollers 15 abut against the side of the auxiliary positioning plate 12 and gradually roll downwards as the sliding positioning frame 14 rotates, reducing resistance during the positioning process and facilitating the contact between the multiple positioning rollers 15 and the auxiliary positioning plate 12, thus stabilizing the support plate 11 from all sides. Simultaneously, the rotating positioning rollers 15 reduce damage to the auxiliary positioning plate 12 during the positioning process.

[0039] When the bidirectional rotary drilling rig 2 is pulled out, the telescopic cylinder 13 drives the end of the sliding positioning frame 14 to rise, moving the positioning roller 15 upward. Since the positioning roller 15 itself cannot rotate upward, there is a certain friction between the positioning roller 15 and the auxiliary positioning plate 12. Multiple sets of positioning rollers 15 use this friction to push the auxiliary positioning plate 12 upward.

[0040] Through the above structural design, positioning rollers 15, which can only rotate in one direction, are installed on the sliding positioning frame 14, which can adapt to both the insertion and extraction of the bidirectional rotary drilling rig 2 from the ground. After the bidirectional rotary drilling rig 2 is inserted into the ground, it is positioned from all sides to avoid collision damage to the device during drilling operations, while ensuring accurate positioning of the bottom of the drilling rig, which helps to improve the positioning accuracy of the anchor bolts. When the bidirectional rotary drilling rig 2 is extracted, the multiple positioning rollers 15 provide additional jacking force to assist its upward movement, solving the problem of the bottom of the bidirectional rotary drilling rig 2 getting stuck after operation, and facilitating its removal from the ground.

[0041] Example 4: Figure 4 , Figure 5 As shown, based on the above embodiment 3, the sliding positioning frame 14 includes: Rack 16, the top of rack 16 is connected to the telescopic end of telescopic cylinder 13, and a locking tooth is provided on the side of rack 16 near auxiliary positioning plate 12; Gear frame 17 is connected to the outer wall of telescopic cylinder 13. Rack 16 slides relative to one end of gear frame 17. Gear mounting space is formed in the middle of gear frame 17. The first transmission gear 18 is rotatably connected to the gear carrier 17 and meshes with the rack 16. The second transmission gear 19 is rotatably connected to the gear carrier 17 and meshes with the other side of the first transmission gear 18. The first swing arm 21 has U-shaped portions at both ends. The U-shaped portion at the first end is connected to the gear shaft of the second transmission gear 19, and the U-shaped portion at the second end is connected to the rotating shaft of the positioning roller 15. The second swing arm 22 is hinged to the second end of the first swing arm 21; The guide slide 23 is connected to the bottom end of the second swing arm 22, and the guide slide 23 is slidably connected to the guide groove on the top of the traveling base 1.

[0042] The working principle and beneficial effects of the above technical solution are as follows: When the auxiliary positioning unit is in use, multiple telescopic cylinders 13 shorten synchronously. The telescopic cylinders 13 drive the rack 16 to move downward. The rack 16 meshes with the first transmission gear 18, and the first transmission gear 18 meshes with the second transmission gear 19, thereby driving the first swing arm 21 to rotate downward. The first swing arm 21 drives the positioning roller 15 at its end to move downward while rotating itself, pressing the auxiliary positioning plate 12 for positioning. At the same time, it drives the second swing arm 22 to rotate downward, pushing the guide slide 23 to slide in the guide groove and move away from the drilling rig through hole 4.

[0043] Conversely, multiple telescopic cylinders 13 extend synchronously, driving the rack 16 to move upward. The rack 16 meshes with the first transmission gear 18, which in turn meshes with the second transmission gear 19, thereby driving the first swing arm 21 to rotate upward. The first swing arm 21 drives the positioning roller 15 at its end to move upward without rotating itself, so that the positioning roller 15 pushes the auxiliary positioning plate 12 upward under the action of friction, assisting the bidirectional rotating drill 2 to be pulled out. At the same time, it drives the second swing arm 22 to rotate downward, pushing the guide slide 23 to slide in the guide groove and approach the drill through hole 4.

[0044] Through the above structural design, the transmission direction is flexibly changed by using gear transmission, which improves the stability of the operation. The first swing arm 21 and the second swing arm 22 jointly support the positioning roller 15. The bottom of the second swing arm 22 slides along a preset path, which improves the movement stability of the positioning roller 15 and ensures accurate positioning. After the positioning roller 15 rises to the preset height, it separates from the bidirectional rotary drilling rig 2 and the distance between them increases, leaving space for the bidirectional rotary drilling rig 2 to be removed from the traveling base 1.

[0045] Example 5: Figure 3 , Figure 6 , Figure 7 As shown, based on the above embodiment 2, a balance limiting seat 30 is provided on the outer side of the auxiliary positioning plate 12. The balance limiting seat 30 includes: The lower seat 31 and the upper seat 32 are connected to the outside of the auxiliary positioning plate 12. The upper seat 32 is movably disposed above the lower seat 31 and multiple vibration damping components are disposed between the two. The top of the upper seat 32 is provided with a V-shaped notch and a rubber pad 33 is provided at the top of the upper seat 32.

[0046] The working principle and beneficial effects of the above technical solution are as follows: During operation, the bottom of the bidirectional rotary drilling rig 2 is inserted into the ground. Insufficient insertion depth can severely affect the stability of the rig. Therefore, a balance limit seat 30 is installed on the auxiliary positioning plate 12. When the insertion depth is insufficient, a gap exists between the positioning roller 15 and the auxiliary positioning plate 12, preventing accurate contact. In this case, the balance limit seat 30 blocks the positioning roller 15, causing it to contact the top of the upper body 32. The V-shaped notch reduces the lateral movement of the positioning roller 15. As the positioning roller 15 moves downward, it presses against the upper body 32 until it contacts the auxiliary positioning plate 12 and reaches the preset positioning position. At this point, under the pressure of the positioning roller 15, the bidirectional rotary drilling rig 2 inserts deeper and reaches the preset insertion depth. The rubber pad 33 is used to reduce impact damage between the positioning roller 15 and the upper body 32.

[0047] Through the above structural design, a balance limit seat 30 is set on the auxiliary positioning plate 12 to form an outward bending structure. During the positioning process, the bidirectional rotary drilling rig 2 is assisted to reach the preset insertion depth, ensuring effective contact between the positioning roller 15 and the auxiliary positioning plate 12, and improving the positioning stability of the bottom of the bidirectional rotary drilling rig 2.

[0048] Example 6: As Figure 6 , Figure 7 As shown, based on the above embodiment 5, the vibration damping component includes: Piston cylinder 34 is mounted on lower seat 31 and has an opening at the top. A floating piston 35 is slidably connected to the upper part of the piston cylinder 34, and the piston rod 36 at its top extends out of the piston cylinder 34 and is connected to the bottom of the upper seat 32. The damping spring 37 is sleeved on the outside of the piston cylinder 34 and the piston rod 36, and its two ends are respectively connected to the lower seat body 31 and the upper seat body 32. A variable piston 38 is slidably connected to the lower part of the piston cylinder 34. An adjusting screw 39 is connected to the bottom of the variable piston 38 and is screwed to the bottom of the piston cylinder 34.

[0049] The working principle and beneficial effects of the above technical solution are as follows: During operation, the positioning roller 15 and the auxiliary positioning plate 12 are in contact. When vibration occurs during operation, the bidirectional rotary drilling rig 2 will move up and down, and the positioning roller 15 will press against the upper seat 32. When the upper seat 32 moves downward under pressure, it presses against the piston rod 36, causing the floating piston 35 to slide inside the piston cylinder 34. At the same time, the elasticity of the damping spring 37 plays a role in damping and buffering the upper seat 32, ensuring accurate positioning while reducing the transmission of vibration to the traveling base 1 and reducing the risk of resonance. For vibrations of different amplitudes in different drilling modes, the variable piston 38 is driven to slide inside the piston cylinder 34 by rotating the adjusting screw 39, adjusting the volume and pressure of the medium inside the piston cylinder 34, and thus adjusting the stiffness of the piston cylinder 34 so that its damping can adapt to vibrations of different frequencies, ensuring the vibration reduction effect in different drilling modes.

[0050] Example 7: As Figure 6 , Figure 7 As shown, based on the above embodiment 1, the top of the lower seat 31 is connected to a limit post 41, and the top of the limit post 41 is connected to a pressure sensor; an alarm is installed on the walking base 1, and the pressure sensor and the alarm are electrically connected to the controller.

[0051] The working principle and beneficial effects of the above technical solution are as follows: A limiting post 41 is installed on the lower seat 31 to limit the sinking distance of the upper seat 32. A pressure sensor is installed on the limiting post 41. During the operation of the bidirectional rotary drilling rig 2, if the force exceeds the limit, causing the bidirectional rotary drilling rig 2 to deflect around the support plate 11, the limiting post 41 in one direction will contact the upper seat 32, while the limiting post 41 in the opposite direction will separate from the upper seat 32. The pressure sensor detects the pressure on the limiting post 41. The controller receives and analyzes the detection signal. When the pressure data deviation exceeds the preset value, it indicates that the support plate 11 is unbalanced, that is, the bidirectional rotary drilling rig 2 has deflected. At this time, the controller activates the alarm to prompt the operator to take action, preventing the bidirectional rotary drilling rig 2 from deflecting further or even colliding with the traveling base 1 and causing danger, thus improving the safety of the operation.
