[0027] This utility model proposes a drill rod disassembly and assembly device for drilling rigs, aiming to solve the problem of low efficiency in disassembling and assembling drill rods during drilling operations in existing drilling equipment.

[0028] Example 1

[0029] See Figure 1 and Figure 2 A drill rod disassembly and assembly device for drilling rigs is disclosed, used for disassembling and assembling drill rods on drilling rigs. It includes a drill rod disassembly and assembly mechanism 1 and a drive mechanism 2. The disassembly and assembly mechanism 1 includes a mounting base 1.1 and a disassembly and assembly component 1.2. The mounting base 1.1 is mounted on the drilling rig. The drive mechanism 2 is mounted on the mounting base 1.1. The first end of the disassembly and assembly component 1.2 is connected to the drive mechanism 2, and the second end is used to grip the drill rod. The drive mechanism 2 can rotate the disassembly and assembly component 1.2 in a vertical plane perpendicular to the drilling direction to install or remove the drill rod from the drilling rig. By using the drive mechanism 2 to drive the disassembly and assembly component 1.2 to rotate in a vertical plane perpendicular to the drilling direction, the gripped drill rod to be installed can be delivered to the drill rod installation position, or the drill rod to be disassembled can be removed from the drilling rig. This avoids the need for construction personnel to carry the drill rod to the drilling height position, effectively improving the efficiency of drill rod disassembly and assembly during the drilling process and reducing the labor intensity and high-altitude operation risks for construction personnel.

[0030] The assembly / disassembly component 1.2 includes a boom 1.2.1, a clamping rod drive 1.2.2, a fixed clamping arm 1.2.3, and a movable clamping arm 1.2.4. The first end of the boom 1.2.1 is connected to the drive mechanism 2, and the second end is connected to the fixed clamping arm 1.2.3. The clamping rod drive 1.2.2 is rotatably connected to the second end of the boom 1.2.1. The movable clamping arm 1.2.4 is rotatably connected to the fixed clamping arm 1.2.3 and also rotatably connected to the output shaft of the clamping rod drive 1.2.2. The clamping rod drive 1.2.2 can drive the movable clamping arm 1.2.4 to move closer to or further away from the fixed clamping arm 1.2.3 to grip or release the drill rod. The clamping rod drive 1.2.2 allows adjustment of the distance between the movable clamping arm 1.2.4 and the fixed clamping arm 1.2.3, enabling both gripping and releasing of the drill rod and accommodating the disassembly / assembly of drill rods of different specifications, effectively improving the applicability of the drilling rod disassembly / assembly device.

[0031] Specifically, the movable clamping arm 1.2.4 includes a hinged section A1 and a clamping rod section A2 connected together. The end of the hinged section A1 away from the clamping rod section A2 is connected to the output shaft of the clamping rod drive 1.2.2, and the middle part of the hinged section A1 is rotatably connected to the fixed clamping arm 1.2.3. The clamping rod section A2 can cooperate with the fixed clamping arm 1.2.3 to grip the drill rod. Under the action of the clamping rod drive 1.2.2, the movable clamping arm 1.2.4 can rotate around the middle part of the hinged section A1, thereby cooperating with the fixed clamping arm 1.2.3 to grip and release the drill rod. The structure is simple, avoiding the need for construction personnel to directly disassemble and assemble the drill rod of the drilling rig, thus ensuring the safety of the construction personnel.

[0032] In this embodiment, both the fixed clamping arms 1, 2, and 3 and the clamping rod section A2 have arc-shaped contact surfaces on their opposite sides. The arc-shaped contact surfaces facilitate the fit between the fixed clamping arms 1, 2, and 3 and the clamping rod section A2 and the drill rod, ensuring stable and secure gripping of the drill rod.

[0033] Furthermore, the drive mechanism 2 includes a drive component 2.1 and a drive shaft 2.2. The drive component 2.1 is mounted on the drive base 1.3; the drive shaft 2.2 is rotatably mounted on the mounting base 1.1 along the drilling direction of the drill pipe, and the first end of the boom 1.2.1 is connected to the drive shaft 2.2. The drive component 2.1 drives the boom 1.2.1 to rotate via the drive shaft 2.2, so as to facilitate the assembly and disassembly of the drill pipe by the boom 1.2.1.

[0034] Furthermore, the drill pipe assembly / disassembly mechanism 1 also includes a drive base 1.3 and an adjustment assembly 1.4. The drive base 1.3 is detachably mounted on the mounting base 1.1. The adjustment assembly 1.4 is located between the drive base 1.3 and the mounting base 1.1, and can adjust the distance between the drive base 1.3 and the drilling rig. The drive base 1.3 has two spaced-apart hinge plates, and the drive shaft 2.2 is rotatably mounted on the two hinge plates. The boom 1.2.1 is connected to the drive shaft 2.2 and located between the two hinge plates. The adjustment assembly 1.4 includes an adjustment bolt and two adjustment plates. The two adjustment plates are respectively mounted on the drive base 1.3 and the mounting base 1.1. The adjustment bolt passes through the two adjustment plates and is rotatably connected to one adjustment plate and threadedly connected to the other adjustment plate. By rotating the adjustment bolt, the distance between the two adjustment plates can be adjusted, thereby adjusting the distance between the drive base 1.3 and the drilling rig. After the drill rod disassembly and assembly device is installed on the drill rig, the distance between the drive seat 1.3 and the drill rig can be adjusted by adjusting component 1.4, which can effectively improve the accuracy of drill rod disassembly and assembly.

[0035] In this embodiment, the mounting base 1.1 has a horizontal support surface 1.1.1, a vertical connecting surface 1.1.2, and an inclined limiting surface 1.1.3. The drive base 1.3 is disposed on the horizontal support surface 1.1.1, and the end of the horizontal support surface 1.1.1 away from the drilling rig forms a clearance groove 1.1.4 for the boom 1.2.1 to pass through. The vertical connecting surface 1.1.2 is connected to the drilling rig by fasteners. The inclined limiting surface 1.1.3 is disposed between the horizontal support surface 1.1.1 and the vertical connecting surface 1.1.2, and the inclined limiting surface 1.1.3 is inclined towards the vertical connecting surface 1.1.2 in the vertically upward direction. The clearance groove 1.1.4 can play a clearance role when the boom rotates downward to grab or release the drill rod. The inclined limiting surface 1.1.3 can abut against the boom 1.2.1 to limit the disassembly assembly 1.2. In this embodiment, the mounting base 1.1 can provide a mounting platform for the drive mechanism 2 and the disassembly assembly 1.2, and can also limit the boom 1.2.1 through the inclined limiting surface 1.1.3, thereby ensuring the drilling rod disassembly and assembly accuracy of the disassembly assembly 1.2.

[0036] Furthermore, the number of drill pipe assembly / disassembly mechanisms 1 is one or more, and each drill pipe assembly / disassembly mechanism 1 is spaced apart along the drilling direction of the drill pipe. In this embodiment, the number of drill pipe assembly / disassembly mechanisms 1 is two, and the two drill pipe assembly / disassembly mechanisms 1 cooperate to perform drill pipe assembly / disassembly operations, further improving operational stability.

[0037] Example 2

[0038] The difference from Embodiment 1 is that the drill rod disassembly and assembly device for the drilling rig also includes a limiting mechanism. The limiting mechanism includes two limiting blocks respectively disposed on the inclined limiting surface and the boom. The two limiting blocks abut against each other to control the disassembly and assembly components. The boom is limited by the limiting mechanism to achieve precise positioning of the drill rod disassembly and assembly position.

[0039] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
