Description

Technical Field

[0001] This utility model relates to the field of drilling rigs, and in particular to a double-tube automatic rod changing mechanism. Background Technology

[0002] In traditional drilling operations, the pipe changing process relies heavily on manual handling and docking of drill pipes and outer casings. This is not only labor-intensive and inefficient, but also prone to affecting alignment accuracy due to human experience, posing safety hazards. Some automated equipment can only dock a single drill pipe or outer casing, lacking a structural design to handle both sets of components simultaneously. This requires completing the pipe changing process in two separate steps, resulting in long downtime and hindering the continuity of pipe changing operations. Utility Model Content

[0003] The purpose of this invention is to provide a dual-tube automatic rod changing mechanism with a high degree of automation and high tube changing efficiency.

[0004] The purpose of this utility model is achieved as follows: a dual-tube automatic rod changing mechanism, including a bottom frame, and a tube storage mechanism and a clamping mechanism placed on the bottom frame.

[0005] The main body of the storage mechanism is fixed to the bottom frame by U-bolts. The storage mechanism is provided with multiple sets of fixing sleeves. The fixing sleeves are provided with outer protective sleeves. A drill rod is fitted inside the outer protective sleeve, and the drill rod protrudes outside the outer protective sleeve.

[0006] The clamping mechanism consists of a horizontal moving seat, an X-axis moving seat, and a Y-axis moving seat. A vertical guide rail is connected to the horizontal moving seat. The Y-axis moving seat is slidably mounted on the vertical guide rail. A horizontal guide rail is provided on the Y-axis moving seat. An X-axis moving seat is provided on the horizontal guide rail. A support rod is connected to the X-axis moving seat. An outer casing clamping manipulator is provided on the side of the support rod near the storage mechanism, and a drill pipe clamping manipulator is provided on the other side away from the storage mechanism.

[0007] Preferably, the lateral moving seat and the bottom frame are connected in a sleeve structure, and the lateral moving seat is driven by a hydraulic cylinder.

[0008] Preferably, the outer sleeve gripping robot is composed of an L-shaped plate and an arc-shaped plate, and the arc-shaped plate is driven by a hydraulic mechanism.

[0009] Preferably, the drill pipe gripping robot is composed of symmetrical clamping plates, and a hydraulic mechanism is hinged between the symmetrical clamping plates; the clamping plates are provided with V-shaped grooves on opposite sides, and multiple sets of anti-slip protrusions are provided in the V-shaped grooves.

[0010] Preferably, the inner surfaces of the L-shaped plate and the arc-shaped plate are provided with a rubber layer. The arc-shaped plate is composed of a vertical surface and an arc-shaped surface, with the arc-shaped surface located below the vertical surface and bent toward the L-shaped plate.

[0011] Preferably, the opening angle of the drill pipe gripping robot is greater than the diameter of the outer casing.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This utility model utilizes a dual-manipulator design (outer casing gripper and drill pipe gripper) in the gripping mechanism to simultaneously grasp the pre-assembled outer casing and drill pipe in the storage mechanism. Combined with the step-by-step docking of the drilling rig docking platform, the entire process requires no manual intervention, effectively reducing manual operation steps and waiting time, and significantly improving the automation level and overall efficiency of pipe changing operations. It is especially suitable for drilling scenarios with high-frequency pipe changing. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1-3 As shown, a dual-tube automatic rod changing mechanism includes a bottom frame 1, a tube storage structure 2 and a clamping mechanism 3 placed on the bottom frame 1.

[0022] The main body of the storage mechanism 2 is fixed to the bottom frame 1 by U-bolts 4. The storage mechanism 2 is provided with multiple sets of fixing sleeves 201. The fixing sleeves 201 are provided with outer protective sleeves 5. Drill rods 6 are fitted inside the outer protective sleeves 5. Drill rods 6 protrude from the outside of the outer protective sleeves 5.

[0023] The clamping mechanism 3 consists of a horizontal moving seat 301, an X-axis moving seat 302, and a Y-axis moving seat 303. A vertical guide rail 7 is connected to the horizontal moving seat 301. The Y-axis moving seat 303 is slidably mounted on the vertical guide rail 7. A horizontal guide rail 8 is provided on the Y-axis moving seat 7. An X-axis moving seat 302 is provided on the horizontal guide rail 8. A support rod 9 is connected to the X-axis moving seat 302. An outer sleeve clamping robot 10 is provided on the side of the support rod 9 closest to the storage mechanism 2, and a drill rod clamping robot 11 is provided on the other side away from the storage mechanism 2. When the support rod is set, it is parallel to the base frame and the fixed sleeve below.

[0024] like Figure 1As shown, the transverse moving seat 301 and the bottom frame 1 are connected by a sleeve structure. The transverse moving seat 301 is driven by the hydraulic cylinder 12. The hydraulic cylinder can drive the transverse moving seat to move on the bottom frame, thereby realizing the overall movement of the clamping mechanism.

[0025] like Figure 2 As shown, the outer casing gripper 10 is composed of an L-shaped plate 1001 and an arc-shaped plate 1002. The arc-shaped plate 1002 is driven by a hydraulic mechanism. Since the outer casing has a large diameter, the arc-shaped plate can be driven by the hydraulic mechanism to grip the outer casing together with the L-shaped plate.

[0026] like Figure 3 As shown, the drill pipe clamping robot 11 is composed of symmetrical clamping plates 1101, and a hydraulic mechanism is hinged between the symmetrical clamping plates 1101. V-grooves 11011 are provided on opposite sides of the clamping plates 1101, and multiple sets of anti-slip protrusions are provided in the V-grooves 11011. The small-diameter drill pipe can be clamped more stably through the V-grooves to avoid loosening.

[0027] like Figure 2 As shown, the inner surfaces of the L-shaped plate 1001 and the arc-shaped plate 1002 are provided with a rubber layer (not shown in the figure). The arc-shaped plate 1002 is composed of a vertical surface 10021 and an arc-shaped surface 10022. The arc-shaped surface 10022 is located below the vertical surface 10021. The arc-shaped surface 10022 is bent toward the L-shaped plate 1001 and can extend into the bottom of the outer protective cylinder to cooperate with the L-shaped plate.

[0028] like Figure 1-3 As shown, the opening angle of the drill pipe gripping manipulator 11 is greater than the diameter of the outer casing 5. A drilling rig docking platform (not shown in the figure, which can move left and right) is provided on the right side of the gripping mechanism. After the outer casing and drill pipe are gripped at the same time, the drilling rig docking platform first docks with the drill pipe at the first docking point. After docking is completed, the drilling rig platform moves to the second docking point and docks with the outer casing. When the whole assembly is released from the gripping mechanism, the large opening angle ensures that the outer casing can pass through the range between the drill pipe gripping manipulators without collision.

[0029] The working principle of this utility model is described as follows: The outer casing and drill rod are stored in the storage mechanism. The clamping mechanism is driven to move laterally by a hydraulic cylinder. Combined with the X and Y axis moving seats, the positions are adjusted so that the outer casing clamping robot and the drill rod clamping robot are respectively aligned with the target. The outer casing clamping robot clamps the outer casing, and the drill rod clamping robot clamps the drill rod. After being transferred to the docking area, the drilling platform first docks with the drill rod, and then moves to dock with the outer casing. After completion, the clamping mechanism resets, realizing an automated rod changing cycle.
