[0042] The rod unloading assembly 500 is configured to be able to receive external force to drive the two clamping blocks 300 to slide away from each other to loosen the drill rod 200. The rod unloading assembly 500 is also configured to be able to reset under the action of the elastic member 400 after the external force is removed, that is, the two clamping blocks 300 are reset and the drill rod 200 is clamped again.

[0043] When installing the rod, first use the rod unloading assembly 500 to drive the two clamping blocks 300 to slide away from each other until the drill rod 200 can be inserted between the two clamping blocks 300, then remove the external force to reset the rod unloading assembly 500 and the clamping blocks 300, and use the two clamping blocks 300 to clamp the drill rod 200. When unloading the rod, use the rod unloading assembly 500 to drive the two clamping blocks 300 to slide away from each other until the drill rod 200 is released.

[0044] The drill rod loading and unloading device for a well drilling rig of the utility model is provided with two clamping blocks 300, and two embedding portions 310 are provided on the clamping blocks 300 to respectively embed into two adjacent clamping grooves 201 on the drill rod 200, and an elastic member 400 is provided to apply elastic force to the clamping block 300 so that the embedding portion 310 of the clamping block 300 can be embedded in the clamping groove 201, thereby clamping the drill rod 200 by the two clamping blocks 300, and a rod unloading assembly 500 is provided, and the two clamping blocks 300 are driven by the rod unloading assembly 500 to slide in a direction away from each other to loosen the drill rod 200, thereby realizing the rod unloading operation, and the structure is very simple.

[0045] Reference Figure 2 As shown, it can be understood that the guide rod 320 is fixedly connected to the side of the block 300 away from the guide hole 101, and the guide rod 320 is horizontally slidably arranged on the base 100. The elastic member 400 is configured as a compression spring and is sleeved on the guide rod 320. The two ends of the compression spring respectively abut the block 300 and the base 100 to apply an elastic force toward the guide hole 101 to the block 300. The structure is simple and practical. Specifically, the guide rod 320 is radially slidably arranged on the base 100 along the guide hole 101.

[0046] Reference Figure 2 , Figure 4 and Figure 5As shown, it can be understood that the outer wall of the base 100 is provided with a mounting hole 102 extending horizontally to the guide hole 101, the mounting hole 102 is provided with an internal thread and threadedly assembled with an adjusting cylinder 110, the adjusting cylinder 110 is provided with an external thread to be threadedly installed in the mounting hole 102, the adjusting cylinder 110 is located on the side of the block 300 away from the guide hole 101, and the adjusting cylinder 110 is at least partially located on the outer peripheral side of the base 100, and a sliding hole is provided in the adjusting cylinder 110 to slide and install the guide rod 320, and the two ends of the compression spring respectively abut the end faces of the adjusting cylinder 110 and the block 300 facing each other. Through the above arrangement, the compression degree of the compression spring when the block 300 clamps the drill rod 200 can be adjusted by screwing the adjusting cylinder 110, that is, the elastic force applied to the drill rod 200 by the adjusting spring through the block 300 can be adjusted, and the flexibility is high. Specifically, the mounting holes 102 are distributed along the radial direction of the guide hole 101.

[0047] Reference Figure 2 As shown, it can be understood that a knob 111 is fixedly provided at one end of the adjustment cylinder 110 facing outward away from the base 100, so that it is convenient for an operator to turn the knob 111 to rotate the adjustment cylinder 110, thereby improving the convenience of use.

[0048] Reference Figure 2 and Figure 4 As shown, it can be understood that the guide rod 320 is threadedly connected with a limit nut 321, and the limit nut 321 is used to limit the end of the adjustment tube 110 away from the base 100, thereby preventing the guide rod 320 from being separated from the adjustment tube 110, and the structure is simple and easy to disassemble and assemble. Of course, the limit nut 321 can be replaced by a pin, so that the pin is penetrated on the guide rod 320.

[0049] Reference Figure 2 , Figure 4 and Figure 6 As shown, it can be understood that the base 100 is provided with a receiving cavity 103 extending to the guide hole 101, and the upper and lower side walls of the receiving cavity 103 are respectively fitted with the upper and lower side walls of the block 300, and the block 300 always remains at least partially located in the receiving cavity 103 during the activity. In this way, the receiving cavity 103 can play a certain guiding and limiting role on the block 300, preventing the block 300 from rotating around the axis of the guide rod 320, thereby improving the stability and reliability of the structure. Specifically, there are two receiving cavities 103, each for accommodating two blocks 300.

[0050] Reference Figure 1 , Figure 3 , Figure 4As shown, it can be understood that the rod unloading assembly 500 includes two abutting rods 510, and the two abutting rods 510 are respectively arranged corresponding to the two blocks 300. The first end of the abutting rod 510 is hinged to the base 100 and the hinge axis of the two is vertically distributed. The abutting rod 510 can swing around the hinge axis of the abutting rod 510 and the base 100, wherein the abutting rod 510 can abut and push the corresponding block 300 away from the guide hole 101 to slide outward when it swings outward, so that the block 300 releases the drill rod 200, and the rod unloading assembly 500 also includes a manual part, which is configured to be able to receive external force to drive the two abutment rods 510 to swing outward synchronously away from the guide hole 101, thereby simultaneously causing the two clamping blocks 300 to swing outward away from the guide hole 101 to loosen the drill rod 200. The manual part is also configured to be able to reset under the action of the elastic member 400 after the external force is removed, wherein, when the external force applied to the manual part is removed, the elastic force pushes the clamping block 300 to reset and re-clamp the drill rod 200. In this process, the direction of the clamping block 300 pushes the manual part to reset, and the structure is simple and practical.

[0051] Further, see Figure 1 , Figure 3 , Figure 4 As shown, the unloading rod assembly 500 also includes a slider 520 and two transmission connecting rods 530. The slider 520 is horizontally slidable along the radial direction of the guide hole 101 and is arranged on the base 100. The first ends of the two transmission connecting rods 530 are respectively hinged to the second ends of the two abutting rods 510, and the hinge axes are vertically distributed. The second ends of the two transmission connecting rods 530 are both hinged to the slider 520, and the hinge axes are vertically distributed. Obviously, when the slider 520 slides, the abutting rod 510 can be driven to swing through the transmission connecting rod 530. In addition, the manual part is used to abut and push the slider 520 to slide to drive The two abutting rods 510 are synchronously swung outward away from the guide hole 101, thereby pushing the two clamping blocks 300 to slide in a direction away from each other, thereby releasing the drill rod 200. The structure is simple and the operation is convenient. When the external force applied to the manual part is removed, the elastic force pushes the clamping block 300 to reset and re-clamp the drill rod 200. In this process, the clamping block 300 resets the manual part through the abutting rod 510, the transmission connecting rod 530, and the slider 520. Through the above arrangement, the two clamping blocks 300 are synchronously swung outward away from the guide hole 101, and the structure is simple and the operation is convenient. In some specific embodiments, an abutting column 330 is provided on the clamping block 300 on the side of the abutting rod 510 away from the guide hole 101, so as to abut against the abutting rod 510.

[0052] Reference Figures 3 to 5As shown, it can be understood that the manual part includes a push rod 540, which is horizontally slidably arranged on the base 100 and the sliding direction is the same as the sliding direction of the slider 520, that is, the push rod 540 is radially slidably arranged on the base 100 along the guide hole 101, wherein a handle 541 is provided at one end of the push rod 540, and the other end is used to abut against the side of the slider 520 away from the guide hole 101, and the push rod 540 is slid relative to the base 100 by operating the handle 541, thereby pushing the slider 520 to slide, and the structure is simple and easy to operate.

[0053] Reference Figures 3 to 5 As shown, it can be understood that the push rod 540 can rotate around its own axis while sliding relative to the base 100. Specifically, the push rod 540 is configured as a cylindrical rod, and the hole on the base 100 for cooperating with the push rod 540 is a cylindrical hole, so that the push rod 540 can rotate around its own axis while sliding relative to the base 100; in addition, an abutment block 542 protruding from the peripheral wall of the push rod 540 is provided at one end of the push rod 540, and the abutment block 542 is used to abut and push the slider 520 to slide. The base 100 is provided with vertically distributed limit grooves 104. When the abutment block 542 slides to align with the limit groove 104, it can rotate to partially embed into the limit groove 104, thereby limiting the sliding of the push rod 540, so as to keep the two blocking blocks 300 in a state of releasing the drill rod 200. In this way, the operator can free his hands to perform operations on the drill rod 200, thereby improving work efficiency.
