For the convenience of understanding, in this embodiment, the length of the chain 330 that is parallel to the limiting groove 210 is defined as the parallel section; referring to Figure 2 As shown, the chain 330 is composed of multiple chain links, and limiting pieces 331 are installed on the chain links of the parallel section. The distance between adjacent limiting pieces 331 is basically equal to the diameter of the drill pipe. The forward and reverse rotation of the chain 330 will drive the drill pipe to be sent out or stored in the limiting groove 210.

[0040] In an embodiment of the present utility model, the chain-type limiting structure 300 further includes a driving wheel 310 and a driven wheel 320. The chain 330 is wound around the driving wheel 310 and the driven wheel 320, and the driving wheel 310 is connected to a driving structure 340 that drives it to rotate. The driving structure 340 is preferably a device such as a motor. The main body structure 200 includes a mounting plate 230, and the driving structure 340 is mounted on the mounting plate 230.

[0041] In an embodiment of the present utility model, the clamping structure 400 includes a fixed seat 410, a clamping member 420, and a third telescopic structure 430. The middle of the clamping member 420 is hinged to the fixed seat 410. The bottom of the clamping member 420 is used to clamp the drill pipe, and the third telescopic structure 430 is used to drive the top of the clamping member 420 to move, so as to drive the bottom of the clamping member 420 to clamp or release the drill pipe. Specifically, referring to Figure 3 、 Figure 4As shown, the clamping member 420 includes a first clamping piece 421 and a second clamping piece 422. The first clamping piece 421 and the second clamping piece 422 are arranged oppositely, and the middle parts of the first clamping piece 421 and the second clamping piece 422 are both hinged to the fixed seat 410; a first claw is provided at the bottom of the first clamping piece 421, and a second claw is provided at the bottom of the second clamping piece 422. The telescopic movement of the movable end of the third telescopic structure 430 can drive the first claw and the second claw to approach or move away from each other. The fixed seat 410 is hinged to the mounting plate 230; the first clamping piece 421 and the second clamping piece 422 have the same shape and size, and the first claw and the second claw also have the same shape and size. The third telescopic structure 430 drives the tops of the first clamping piece 421 and the second clamping piece 422 to approach or move away from each other, thereby driving the first claw at the bottom of the first clamping piece 421 and the second claw at the bottom of the second clamping piece 422 to approach or move away from each other; when the first claw and the second claw approach each other, they can clamp the drill pipe, and when the first claw and the second claw move away from each other, they can release the clamping of the drill pipe.

[0042] Further, in the embodiment of the present invention, the fixed seat 410 includes a mounting piece 411. The mounting piece 411 is arranged between the first clamping piece 421 and the second clamping piece 422. A first elastic structure 440 is provided between the first clamping piece 421 and the mounting piece 411, and a second elastic structure 450 is provided between the second clamping piece 422 and the mounting piece 411; the third telescopic structure 430 includes a cylinder body 431 and a telescopic rod 432. The telescopic rod 432 passes through the first clamping piece 421, the mounting piece 411 and the second clamping piece 422. Both the first elastic structure 440 and the second elastic structure 450 are sleeved on the outer periphery of the telescopic rod 432. Specifically, referring to Figure 3 、 Figure 4 As shown, the first end of the telescopic rod 432 is slidably installed in the cylinder body 431, and the cylinder body 431 drives the telescopic rod 432 to slide through connecting pneumatic or hydraulic power. The mounting piece 411 is integrally connected with the fixed seat 410. Through holes for the telescopic rod 432 to pass through are provided at the tops of both the first clamping piece 421 and the second clamping piece 422. However, it should be noted that the diameters of the through holes for the telescopic rod 432 to pass through at the tops of the first clamping piece 421 and the second clamping piece 422 are both larger than the diameter of the telescopic rod 432. The first elastic structure 440 is preferably a spring, and the second elastic structure 450 is also preferably a spring. The first elastic structure 440 is used to drive the first claw to move towards the second claw, and the second elastic structure 450 is used to drive the second claw to move towards the first claw.

[0043] In the embodiment of the present invention, a locking nut 433 is connected to the end of the telescopic rod 432. A first conical washer 460 and a first spherical washer 461 are provided between the locking nut 433 and the first clamping piece 421. Both the first conical washer 460 and the first spherical washer 461 are sleeved on the telescopic rod 432, and the first spherical washer 461 can rotate relative to the first conical washer 460. Specifically, referring toFigure 4 , Figure 5 As shown in Figure 5 , the aperture of the hole in the first conical washer 460 through which the telescopic rod 432 passes is larger than the diameter of the telescopic rod 432, and the aperture of the hole in the first spherical washer 461 through which the telescopic rod 432 passes is basically the same as the diameter of the telescopic rod 432. Since the middle part of the first clip 421 is hinged to the fixed seat 410, when the first clip 421 rotates around its hinge with the fixed seat 410, that is, when the top of the first clip 421 moves towards the second clip 422, part of the top of the first clip 421 will rise. And the telescopic rod 432 is straight, so it is necessary to set the first conical washer 460 and the first spherical washer 461, and the first conical washer 460 and the first spherical washer 461 can rotate relative to each other. In this way, the relative rotation of the first conical washer 460 and the first spherical washer 461 can balance the change in the height of the top of the first clip 421 when the top of the first clip 421 moves towards the top of the second clip 422.

[0044] It should be noted that both the first conical washer 460 and the first spherical washer 461 are arranged on the side of the first clip 421 facing away from the second clip 422. The first conical washer 460 has a conical surface, and the first spherical washer 461 has a spherical surface. The spherical surface of the first spherical washer 461 contacts the conical surface of the first conical washer 460.

[0045] In the embodiment of the present utility model, a first retaining ring 462 is further provided between the lock nut 433 and the first conical washer 460. A second conical washer, a second spherical washer and a second retaining ring are provided between the cylinder block 431 and the second clip 422. The second conical washer is the same in shape, size and structure as the first conical washer 460, and the second spherical washer is the same in shape, size and structure as the first spherical washer 461. The second conical washer cooperates with the second spherical washer, and the function it plays is the same as that played by the first conical washer 460 and the first spherical washer 461. Since the lock nut 433 is provided, when part of the telescopic rod 432 retracts into the cylinder block 431, the first elastic structure 440 and the second elastic structure 450 will be compressed, and then drive the first claw and the second claw to move away from each other to loosen the drill pipe; when the telescopic rod 432 slides in the direction away from the cylinder block 431, it will drive the first claw and the second claw to move closer to each other to clamp the drill pipe.

[0046] A drill rig according to an embodiment of the second aspect of the present utility model includes the above drill pipe storage assembly; specifically, the drill pipe storage assembly of this embodiment is only used for storing drill pipes and driving the drill pipes to move, and then the position of the drill pipes is fixed by the clamping structure 400; the drill rig according to an embodiment of the second aspect of the present utility model includes a rock drill disposed above the drill pipe storage assembly. After the rock drill is connected to the drill pipe clamped by the clamping structure 400, the clamping structure 400 releases the drill pipe, and the rock drill drives the drill pipe to perform further drill pipe operations.
