[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] refer to Figures 1 to 7A fast rod-raising and lowering drilling rig includes a chassis 1, a drill frame 2, a tower cylinder 3, a feed frame 4, a power head 5 and a clamp 6. The drill frame 2 is hinged to the chassis 1, and the drill frame 2 can adjust its angle relative to the chassis 1. The tower cylinder 3 is movably connected to the chassis 1 and the drill frame 2 respectively. The tower cylinder 3 is used to drive the drill frame 2 to adjust its angle relative to the chassis 1. The feed frame 4, the power head 5 and the clamp 6 are all located on the drill frame 2; the feed frame 4 is used to drive the power head 5 to reciprocate along the drill frame 2, the power head 5 is used to realize the axial movement and rotation of the drill rod, and the clamp 6 is used to clamp and release the drill rod.

[0032] The above-mentioned fast rod-up and down drilling rig also includes a drill rod box mechanism 7 and a drill rod manipulator 8, both of which are located on the chassis 1, and the drill rod manipulator 8 is located between the drill frame 2 and the drill rod box mechanism 7; the drill rod box mechanism 7 is used to store and supply drill rods; the drill rod manipulator 8 is used to load and unload drill rods onto the power head 5, thereby realizing automated drill rod up and down operations.

[0033] The drill rod box mechanism 7 includes a box frame 71 , which is hinged to the chassis 1 ; the box frame 71 is used to store drill rods.

[0034] The drill rod manipulator 8 is hinged to the chassis 1, and the drill rod manipulator 8 can be flipped up or down relative to the chassis 1; the feed frame 4, the power head 5 and the clamp 6 are all located on the side of the drill frame 2 facing the drill rod manipulator 8 to reduce the path length of the drill rod manipulator 8 for loading and unloading drill rods.

[0035] When the drill rig 2 is driven to an upright position by the tower cylinder 3, the drill rod manipulator 8 can rise and flip from a position close to the drill rod box mechanism 7 to a position close to the power head 5 on the drill rig 2, thereby realizing convenient and fast loading and unloading of the drill rod.

[0036] The box frame 71 is in the form of a frame with an opening facing upwards, which is convenient for taking and placing the drill rod; when the box frame 71 is flipped relative to the chassis 1, the opening of the box frame 71 is tilted toward the drill rod manipulator 8, so that the drill rod manipulator 8 can take out or put in the drill rod.

[0037] The drill rod box mechanism 7 also includes a box seat 73 and a flip cylinder 75. The box seat 73 is located on the chassis 1, and the box frame 71 is hinged to the box seat 73; the two ends of the flip cylinder 75 are respectively hinged to the chassis 1 and the box frame 71, and the flip cylinder 75 is used to drive the box frame 71 to flip relative to the box seat 73.

[0038] A movable hook 72 is provided on the box frame 71. The movable hook 72 is specifically located at one side of the opening of the box frame 71 close to the box seat 73. The movable hook 72 is L-shaped and moves together with the box frame 71 to position the drill rod.

[0039] A fixing hook 74 is provided on the box seat 73. The fixing hook 74 is specifically located at the top of the box seat 73 and is close to the movable hook 72. The fixing hook 74 is L-shaped and is fixedly provided on the box seat 73 for positioning the drill rod.

[0040] The drill rod manipulator 8 includes a telescopic arm 81, a lifting cylinder 82 and a drill rod clamp 84. The drill rod manipulator 8 is used to clamp and carry the drill rod; the flip axis of the telescopic arm 81 is in the same straight line as the flip axis of the drill rig 2, so that when the telescopic arm 81 and the drill rig 2 are flipped and raised at the same angle, the axis of the drill rod on the drill rod manipulator 8 is in the same axis or parallel to the axis of the output shaft of the power head 5, thereby eliminating the operation of adjusting the angle, orientation and posture, which is conducive to shortening the moving path of the drill rod, and further conducive to quickly raising and lowering the drill rod.

[0041] The two ends of the lifting cylinder 82 are respectively hinged to the chassis 1 and the telescopic arm 81. The lifting cylinder 82 is used to drive the telescopic arm 81 to flip up or down. The drill rod clamp 84 is located at the end of the telescopic arm 81. The drill rod clamp 84 is used to clamp or release the drill rod.

[0042] When the telescopic arm 81 is lowered, the drill rod gripper 84 aligns with the position of the box frame 71. When the telescopic arm 81 is raised, the drill rod gripper 84 aligns with the position of the power head 5 on the drill rig 2, thereby facilitating the transfer of the drill rod. A clamping block 841 is movably provided at the end of the drill rod gripper 84, which is used to clamp or release the drill rod from both sides.

[0043] The telescopic arm 81 is also provided with a positioning plate 83, which corresponds to the position of the drill rod clamp 84; the positioning plate 83 is provided with a positioning groove, which corresponds to the position of the clamping block 841. The positioning groove is used to position the drill rod to reduce the chance of the drill rod falling.

[0044] It also includes a tower lifting mechanism 9, which includes a tower lifting cylinder 91 and a guide turning frame 92; the guide turning frame 92 is hinged to the chassis 1, and the tower lifting cylinder 3 drives the guide turning frame 92 to turn up and down. The drilling rig 2 can be movably set on the guide turning frame 92, and the guide turning frame 92 can provide guidance for the movement of the drilling rig 2.

[0045] Both ends of the tower lifting cylinder 91 are hinged to the drill frame 2 and the guide turning frame 92 respectively. The tower lifting cylinder 91 is used to drive the drill frame 2 to reciprocate relative to the guide turning frame 92.

[0046] The specific working sequence of this utility model is:

[0047] The crawler tracks of the chassis 1 are used for walking. When the chassis 1 reaches the designated working position, the chassis 1 stops and the supporting legs on the side of the chassis 1 are lowered to fix the chassis 1.

[0048] Then the piston rod of the tower lifting cylinder 3 is extended to drive the guide turning frame 92 to rise upward relative to the chassis 1 until the drilling frame 2 is perpendicular to the ground or at a specific angle.

[0049] The piston rod of the tower lifting cylinder 91 moves, driving the drill frame 2 to move relative to the guide turning frame 92 until it reaches a suitable position and stops.

[0050] The drill rod is manually placed horizontally into the box frame 71 of the drill rod box mechanism 7; when the drill rod needs to be put on, the piston rod of the flip cylinder 75 is extended, driving the upper open end of the box frame 71 to flip toward the drill rod manipulator 8 until the upper drill rod in the box frame 71 rolls into the movable hook 72 on the top of the box frame 71.

[0051] When the drill rod rolls into the movable hook 72, it also enters the fixed hook 74 on the box seat 73; then the piston rod of the lifting cylinder 82 extends, driving the telescopic arm 81 to flip and rise upward, and the positioning groove on the positioning plate 83 and the clamping block 841 of the drill rod clamp 84 remove the drill rod from the movable hook 72 and the fixed hook 74.

[0052] The clamping block 841 moves to clamp the drill rod until the telescopic arm 81 is parallel to the drill frame 2, at which time the drill rod is facing the output shaft of the power head 5.

[0053] Feed frame 4 drives power head 5 downward along drill frame 2. The output shaft of power head 5 screws into the top of the drill rod. Clamp block 841 is then released, and lift cylinder 82 lowers telescopic arm 81 to reset it. Power head 5 then drives the drill rod downward and rotates it, engaging it with another drill rod in gripper 6. Power head 5 continues to drive the drill rod downward and rotate, completing the drilling operation.

[0054] The drill rod disassembly process is the opposite and will not be described in detail.

[0055] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention should be understood to be within the scope of protection of the present invention.
