[0032] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0033] Example 1

[0034] Please combine Figure 1 The vehicle-mounted multi-axis anchor bolt drilling rig includes a body (not marked), a drilling rig moving guide rail 2, a drilling rig hydraulic motor 3, an auxiliary boom 4, a drill rod 16, and a docking device. The auxiliary boom 4 is located in the body. The drilling rig moving guide rail 2 is mounted on the auxiliary boom 4. The drilling rig hydraulic motor 3 is mounted on the drilling rig moving guide rail 2 and can move relative to it. The drill rod 16 is driven by the motor output shaft 15 of the drilling rig hydraulic motor 3 and rotates synchronously with the motor output shaft 15.

[0035] In addition, the vehicle-mounted multi-axis anchor bolt drilling rig of this embodiment also includes a drill bit holder 1, a drill rod thrust cylinder 5, a secondary boom power joint 6, a telescopic boom 7, a main boom 8, a main boom power joint 9, a turntable 10, a vehicle platform 11, a KST track assembly 12, and a support cylinder 13.

[0036] The drill bit holder 1 is installed on the drilling rig moving guide rail 2 at the end away from the drilling rig hydraulic motor 3. The KST track assembly 12 and the vehicle platform 11 form the walking assembly. The turntable 10 is driven by the rotation drive assembly under the vehicle platform to achieve 360° rotation. The main boom power joint 9 is driven to rotate by the reduction hydraulic motor assembly, causing the main boom 8 to rotate 180 degrees. The telescopic boom 7 is driven by the telescopic power inside the main boom to extend and retract along the main boom. The auxiliary boom power joint 6 drives the auxiliary boom 4 to rotate 180°. The drilling rig moving guide rail 2 is fixed on the auxiliary boom 4. Driven by the drill rod thrust cylinder, the drilling rig hydraulic motor 3 drives the moving base 14 to move linearly along the drilling rig moving guide rail 2, thereby advancing the drill rod 16, which is connected to the drilling rig hydraulic motor 3 and rotates. The drill bit holder 1 is used to fix the direction of drill rod 16 advancement. The four corner support cylinders 13 of the vehicle body are used for vehicle body positioning. At a system pressure of 20MPa, the torque is 2000Nm. The vehicle body is 1.2m wide and can climb slopes of ≤25°.

[0037] Please combine Figures 2 to 6 The docking device includes a first cylinder 17 and a locking mechanism. The first cylinder 17 has a first insertion port (not marked) and a second insertion port (not marked) at both ends. The first insertion port and the second insertion port can be used to insert the motor output shaft 15 and the drill rod 16 into the first cylinder 17, respectively. The locking mechanism is used to lock and fix the motor output shaft 15 and the drill rod 16, so as to realize the effective transmission of the motor output shaft 15 to the drill rod 16.

[0038] The locking mechanism includes a second rocker arm 30 housed within the first cylindrical body 17. The second rocker arm 30 is distributed along the axial direction of the first cylindrical body 17. One end of the second rocker arm 30 is disposed on the inner wall of the first cylindrical body 17, and the other end is rotatable radially relative to the first end. A second locking block 31 is disposed on the side of the other end of the second rocker arm 30 facing the central axis of the first cylindrical body 17.

[0039] One end of the motor output shaft 15 is provided with a rod slot 34 for inserting the drill rod 16. The outer periphery of the drill rod 16 is provided with a second groove 33 that cooperates with the second locking block 31. The outer periphery of the motor output shaft 15 is provided with a second through groove 32 for the second locking block 31 to pass into the rod slot 34.

[0040] In this embodiment, the motor output shaft 15 and the drill rod 16 are respectively inserted into the first cylinder 17 through the first socket and the second socket, and one end of the drill rod 16 is inserted into the rod slot 34 on the motor output shaft 15. Then, the second rocker arm 30 is guided to rotate centripetally so that the second locking block 31 on it passes through the second through slot 32 and is locked into the second locking slot 33, so as to achieve relative fixation between the motor output shaft 15 and the drill rod 16, and to synchronize the movement of the three components: the motor output shaft 15, the drill rod 16 and the first cylinder 17.

[0041] A fixing block 28 is radially arranged in the first cylinder 17. A first gear 21 and a second gear 29 are meshed opposite each other on the fixing block 28. In this embodiment, two rotating shafts 35 are rotatably inserted into the fixing block 28. The first gear 21 and the second gear 29 are fixedly sleeved on the outside of the two rotating shafts 35 to move synchronously with the two rotating shafts 35. A rotating hole (not shown) is opened on the fixing block 28, and the rotating shaft 35 is inserted into the rotating hole. A coil spring (not shown) is arranged between the outer wall of the rotating shaft 35 and the inner wall of the rotating hole. When the coil spring does not deform, the separated ends of the first rocker arm 22 and the second rocker arm 30 are centrifugally distributed.

[0042] The second rocker arm 30 is fixed to the second gear 29 at the end away from the second locking block 31 and rotates synchronously with the second gear 29. The first rocker arm 22 is fixed on the first gear 21 and rotates synchronously with it.

[0043] The outer circumference of the first cylinder 17 is provided with an arc-shaped first through groove 27, and a first ring body 25 is rotatably sleeved on the outer circumference of the first cylinder 17, the first ring body 25 corresponding to the outer position of the first through groove 27. A first pressure block 26 is provided on the inner side of the first ring body 25, the first pressure block 26 movably passes through the first through groove 27 and extends into the first cylinder 17.

[0044] The first pressure block 26 has a centripetal curved crescent-shaped structure, and the radial length of the crescent-shaped structure gradually increases in its bending direction. When the first pressure block 26 rotates with the first ring body 25, it will gradually apply a centripetal squeezing force to one end of the first swing rod 22, causing the first swing rod 22 to rotate.

[0045] In this embodiment, by rotating the first ring body 25, the first pressure block 26 is driven to slide and squeeze the first swing rod 22, forcing one end of the first swing rod 22 to rotate radially inward, and the other end drives the first gear 21 to rotate. The first gear 21 drives the second swing rod 30 to rotate through the second gear 29, so that the end of the second swing rod 30 away from the first swing rod 22 rotates radially inward, so that the second locking block 31 is locked into the second locking groove 33.

[0046] The outer side of the first cylinder 17 is fitted with a second ring 37 that can move relative to it along its axial direction. The second ring 37 is located on the side of the first ring 25 away from the drilling rig hydraulic motor 3. The ring wall of the second ring 37 facing the first ring 25 is provided with an axially extending third locking block 38. The first ring 25 is provided with at least one third locking groove 36 that cooperates with the third locking block 38.

[0047] In this embodiment, by inserting the third locking block 38 on the second ring body 37 into the third locking groove 36 of the first ring body 25, the rotation of the first ring body 25 can be prevented, so that the first ring body 25 always remains stationary, thereby maintaining the connection stability between the motor output shaft 15 and the drill rod 16.

[0048] The outer periphery of the first cylinder 17 is provided with an axially extending limiting groove 39. A guide rod 41 is axially arranged in the limiting groove 39. A limiting block 40 that can move relative to the limiting groove 39 is slidably sleeved on the outer side of the guide rod 41. The centrifugal end of the limiting block 40 is fixedly connected to the corresponding inner wall of the second ring 37. A spring 42 is sleeved on the outer side of the guide rod 41. The two ends of the spring 42 are respectively fixed on the side of the limiting block 40 away from the drilling rig hydraulic motor 3 and on the corresponding inner wall of the limiting groove 39. When the spring 42 does not deform, the third locking block 38 on the second ring 37 is engaged in the third locking groove 36 of the first ring 25.

[0049] In this embodiment, the elastic force of the spring 42 can always provide the second ring 37 with a thrust in the direction of the drilling rig hydraulic motor 3, so that the third locking block 38 on the second ring 37 is always locked in the third locking groove 36.

[0050] During disassembly, the second ring 37 needs to be temporarily manually moved away from the first ring 25 to temporarily compress the spring 42, so that the third locking block 38 can disengage from the third locking groove 36. Then, the first ring 25 is rotated in the opposite direction to gradually release the downward pressure of the first pressure block 26 on the first rocker arm 22. Under the action of the spring on the rotating shaft 35, the first rocker arm 22 is driven to gradually return to the initial position, thereby causing the second locking block 31 to disengage from the second locking groove 33, thus releasing the locking state between the motor output shaft 15 and the drill rod 16.

[0051] In this embodiment, a first locking block 23 is provided on the side of the first rocker arm 22 away from the second rocker arm 30 and facing the central axis of the first cylinder 17. A first slot 24 is provided on the outer side of the drill rod 16 to engage with the first locking block 23. When the first rocker arm 22 is pressed, the first locking block 23 on it will be engaged in the first slot 24 to achieve relative fixation between the first cylinder 17 and the drill rod 16, making the connection between the motor output shaft 15, the drill rod 16, and the first cylinder 17 more stable.

[0052] The bottom of the hydraulic motor 3 of the drilling rig is provided with a first bracket 19, which is supported and fixed to the top of the movable base 14. The outer periphery of the first cylinder 17 is fitted with a second cylinder 18, which can rotate relative to the second cylinder 18. The bottom of the second cylinder 18 is provided with a second bracket 20, which is supported and fixed to the top of the movable base 14.

[0053] Example 2

[0054] Please combine Figures 7 to 10 In this embodiment, which is an improvement on embodiment 1, a third ring 44 is sleeved on the outer periphery of the first cylinder 17. The third ring 44 acts on the second ring 37, causing the second ring 37 to move toward the first ring 25, so that the third locking block 38 is engaged in the third locking groove 36 of the first ring 25. The third ring 44 can move axially along the outer periphery of the first cylinder 17, providing a squeezing force to the second ring 37, so that the third locking block 38 is always locked in the third locking groove 36, which is stable and reliable.

[0055] A second pressure block 45 is provided on the side of the third ring body 44 facing the second ring body 37, and a pressure-bearing slope 43 is provided on the outer periphery of the second ring body 37 facing the third ring body 44.

[0056] In this embodiment, the second pressure block 45 has a right-angled trapezoidal cross-section. The hypotenuse of the right-angled trapezoidal structure faces the center of the third ring 44, and the inclination direction is from the side of the third ring 44 closest to the second ring 37 toward the side away from the second ring 37. The pressure-bearing slope 43 has a slope surface (not shown) that matches the inclination direction of the hypotenuse of the trapezoidal structure.

[0057] By using the active compression of the second pressure block 45 and the pressure-bearing slope 43, the third ring 44 can effectively compress the second ring 37, thus preventing accidental loosening.

[0058] A connecting groove 46 is provided around the outer periphery of the first cylinder 17 at the end away from the hydraulic motor 3 of the drilling rig. The third ring 44 is threadedly connected to the connecting groove 46. The third ring 44 can be moved on the connecting groove 46 by screwing to provide a stable extrusion force for the second ring 37, which is safe and reliable.

[0059] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
