It is understood that the following embodiments are only exemplary descriptions of the utility model and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0022] This application is based on the research and development ideas of "5G" smart mines. Traditional mining operations require a lot of manpower and material resources, and the working environment is harsh. There is no reasonable planning and the mining efficiency is low. Therefore, it is particularly important to combine the current 5g technology for the technical research and development of mining operations, which plays a vital role in greatly improving the efficiency and safety of mining operations. At present, the main operations of open-pit mines are "drilling, shoveling, and driving", among which unmanned drilling rigs are particularly important. During the use of the drilling rig, the drill rod needs to be disassembled and assembled frequently. It is very necessary to provide an auxiliary tooling that can realize fully automatic unmanned mechanical loading and unloading of the drill rod for the construction of smart mines.

[0023] This embodiment provides a drilling rig automatic rod connection and disconnection tooling, which has a plurality of slots arranged at intervals along the circumferential direction at the threaded connection end of the drill rod, see Figures 1 to 4 The automatic rod-loading tooling for drilling rigs includes an upper clamping member 1 fixed on the power head of the drilling rig and a lower clamping member 2 fixed on the drilling platform 4 of the drilling rig, see Figure 1 , Figure 2 As shown, the upper clamp 1 is provided with a first through hole 11 for the drill rod to pass through, the sleeve 3 of the drilling rig power head is connected to the first through hole 11 and fixed on the upper clamp 1, and a rotatable drill rod fixing piece is provided on the upper clamp 1. The drill rod fixing piece is centrally symmetrical with the center of the first through hole 11 as the symmetry point, and the drill rod fixing piece is rotated to be clamped into the clamping groove of the drill rod. The centrally symmetrical drill rod fixing piece provides a pair of reverse forces for the drill rod to achieve the effect of clamping and fixing the drill rod; specifically, the drill rod fixing piece includes a clamping claw 12 and a claw cylinder 13, the claw 12 is hingedly mounted on the upper clamp 1 through a pin shaft Ⅰ 14, the claw cylinder 13 is fixedly mounted on the upper clamp 1 through a pin shaft Ⅱ 15, the claw 12 and the cylinder head of the claw cylinder 13 are hinged together through a pin shaft Ⅲ 16, and the extension and retraction action of the claw cylinder 13 can drive the claw 12 to rotate along the center point of the pin shaft Ⅰ 14 and clamp it into the clamping groove of the drill rod, so as to adapt to the clamping of drill rods of different specifications and sizes, and the claw cylinder 13 provides a continuous force for the claw 12.

[0024] See also Figure 3 , Figure 4As shown, the lower clamping member 2 includes a base plate 21, a clamping plate 22 and a clamping cylinder 23. The base plate 21 is fixed on the drilling platform 4. The clamping cylinder 23 is fixed on the drilling platform 4 through a cylinder seat 231. The base plate 21 is provided with a second through hole 211 for the drill rod to pass through. A stabilizing rod sleeve 212 is sleeved in the second through hole 211. A bayonet 221 and a cylinder connecting sleeve 222 are provided on the clamping plate 22. The clamping plate 22 is connected to the clamping cylinder 23 through the cylinder connecting sleeve 222. The cylinder head of the clamping cylinder 23 is fixed in the cylinder connecting sleeve 222 by a bolt 24, so that the clamping plate 22 is extended through the extension action of the clamping cylinder 23 to make the drill rod clamped in the bayonet 221. The bayonet 221 clamps the drill rod by cooperating with the stabilizing rod sleeve 212. The clamping oil cylinder 23 is equipped with a magnetostrictive displacement sensor, which can accurately measure and control the displacement of the clamping plate 22 to ensure the clamping of the drill rod. Baffles 25 are fixed on both sides of the bottom plate, and the pressure strip 26 is fixed on the baffle 25 by screws 27 to form a clamping device. The clamping plate 22 is set in the groove between the pressure strip 26 and the bottom plate 21.

[0025] The lower clamp 2 clamps drill rods of different specifications by using rod stabilizing sleeves of different sizes and clamping plates with different sizes of bayonet. The clamping operation of drill rods of different specifications can be achieved by replacing the rod stabilizing sleeve and the clamping plate. The rod stabilizing sleeve 212 can be sleeved and fixed in the second through hole 211 by sleeve connection, bolt fixing, etc. The clamping plate 22 is connected to the clamping cylinder 23 through the cylinder connecting sleeve 222. The replacement method of the rod stabilizing sleeve and the clamping plate is simple and easy to operate. The rod stabilizing sleeve positions and guides the drill rod toward the center, and is preferably made of cast iron or cast steel.

[0026] The action flow of loading and unloading the drill pipe using the tooling provided in this embodiment is as follows:

[0027] 1. Drill rod connection: When the drilling rig has drilled the first drill rod to the depth required to connect the second drill rod, the clamping cylinder 23 of the lower clamp 2 extends, driving the clamping plate 22 to extend so that the bayonet 221 clamps the first drill rod. The first drill rod is clamped and fixed by the bayonet 221 and the rod stabilizing sleeve 212. The power head reverses and retracts the buckle to separate the first drill rod from the power head (unloading the rod), then the power head rises, the rod magazine extends, the power head descends, the power head forwardly rotates and connects with the second drill rod (connecting the rod), the power head rises, the rod magazine is retracted, and the power head is reversed. The power head descends, and the power head forwardly turns the buckle to connect the second drill rod with the first drill rod (connecting rod). After the connection is completed, the clamping cylinder 23 retracts, driving the clamping plate 22 to retract the drill rod and disengage the drill rod from the clamping groove 221. Then, drilling continues until the second drill rod is drilled to a depth that requires the third drill rod to be connected. The above-mentioned action is repeated, and the lower clamp 2 clamps the second drill rod to disengage the second drill rod from the power head. Then, the power head connects the third drill rod, and the third drill rod is connected to the second drill rod, and the third drill rod is connected to the second drill rod, and the connection of the third drill rod is completed. In this way, multiple drill rods can be connected.

[0028] 2. Disassembly of drill rods: For the convenience of description, the drill rods are divided into the first drill rod, the second drill rod, and the Nth drill rod from top to bottom with the power head as the starting point. It can be understood that the "first drill rod" and "second drill rod" here are only used for description purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. After the drilling rig has drilled all the drill rods to the depth, the power head rises and first drives the first drill rod and the second drill rod to extend out of the borehole, the lower clamp 2 clamps the second drill rod, and the upper clamp 1 clamps the first drill rod. The power head reverses the shackle to separate the second drill rod from the first drill rod (unloading the rod), the power head rises, the rod warehouse extends the manipulator to grab the first drill rod, the power head reverses the shackle to separate the first drill rod from the power head (unloading the rod), the power head rises, the rod warehouse retracts the first drill rod, the power head descends, and the power head forwards the buckle to connect with the second drill rod (connecting the rod), completing the disassembly of the first drill rod and the second drill rod. Repeat the above actions several times to complete the disassembly of multiple drill rods.

[0029] All of the above actions can be controlled through the remote control operation platform.

[0030] In summary, the automatic connecting and unloading tooling for drilling rigs provided in the above embodiments can cooperate with the power head to complete the actions of forward connection (connecting rod) and reverse withdrawal (unloading rod) by providing upper and lower clamps fixed on the drilling rig equipment to clamp the two drill rods to be loaded and unloaded respectively, thereby realizing the mechanical and automated loading and unloading operations of the drill rods of the drilling rig; the action of the upper clamp is driven by the air cylinder, and the action of the lower clamp is driven by the oil cylinder, and the action is stable and can be remotely controlled, thereby realizing unmanned operation of drilling rod loading and unloading, and facilitating the construction of smart mines.
