[0040] Combined with Figures 1 to 4 As shown, according to a specific embodiment of the present application, an oilfield trailer-mounted automated multi-functional pipe arrangement system is provided.

[0041] The oilfield trailer-mounted automated multi-functional pipe arrangement system includes a tubing storage box 1, a pipe gripping device 2, and a chassis 4. The tubing storage box 1 has a tubing installation position for accommodating at least one tubing 3. The pipe gripping device 2 at least includes a pipe gripper 21, and the pipe gripper 21 is used for gripping the tubing 3. A conveying track 41 is provided on the chassis 4.

[0043] Furthermore, at least one of the oil pipe storage box 1 and the pipe grasping device 2 is movably connected to the chassis 4, so that at least one of the oil pipe storage box 1 and the pipe grasping device 2 has a working state perpendicular to the chassis 4 and a storage state lying flat on the chassis 4. This can facilitate the transportation of the oilfield trailer-mounted automated multi-functional pipe arranging system.

[0044] In an exemplary embodiment of the present application, both the oil pipe storage box 1 and the pipe grasping device 2 are movably connected to the chassis 4. When the oilfield trailer-mounted automated multi-functional pipe arranging system is in the working state, both the oil pipe storage box 1 and the pipe grasping device 2 are in the vertically placed state, and the oil pipe storage box 1 and the pipe grasping device 2 are located on both sides of the conveying track 41 parallel to each other to achieve efficient and accurate grasping of the oil pipe for operation; when the oilfield trailer-mounted automated multi-functional pipe arranging system is in the storage state, the oil pipe storage box 1 and the pipe grasping device 2 are laid down on the chassis 4, which is convenient for efficient mobile transportation and equipment deployment.

[0045] Preferably, the oil pipe storage box 1 is connected to the chassis 4 through a hinge 5, which is convenient for the assembly and maintenance of the oil pipe storage box 1; the pipe grasping device 2 is designed with a folding structure and can be folded and laid down on the chassis 4, with flexible operation and improved space utilization rate of the oilfield trailer-mounted automated multi-functional pipe arranging system.

[0046] Specifically, the oil pipe storage box 1 includes a box body 10 and a box body support assembly. The box body 10 has at least one oil pipe installation position. A pipe feeding hole 100 is opened on the side wall of the box body 10 facing the pipe grasping device 2. The oil pipe 3 grasped by the pipe grasping device 2 enters the box body 10 through the pipe feeding hole 100; the box body support assembly is arranged on the outer side wall of the box body 10, and the box body 10 is fixed to the ground through the box body support assembly. The arrangement that the pipe feeding hole 100, the pipe grasping device 2 and the grasped oil pipe 3 are in the same plane can accurately and efficiently place the oil pipe 3 into the oil pipe storage box 1 during the pipe grasping operation, improving the operation efficiency. The box body support assembly is provided to fix the box body 10 and enable the operation process to proceed stably, avoiding the influence of the shaking of the box body 1 on the oil pipe storage operation.

[0047] Among them, a plurality of oil pipe installation positions are provided in the box body 10, and each oil pipe installation position is used to install an oil pipe 3. The plurality of oil pipe installation positions are arranged in an array. The plurality of oil pipe installation positions can be used to install and store a plurality of oil pipes 3. The array arrangement of the plurality of oil pipe installation positions can increase the storage quantity of the oil pipes 3 inside the box body 10, make the arrangement of the oil pipes neat, improve the space utilization rate, and further improve the operation efficiency.

[0048] Specifically, the oil pipe storage box 1 further includes a limiting rod 12. One end of the limiting rod 12 is connected to the box body 10. The limiting rod 12 extends along the length direction of the box body 10. A plurality of oil pipe clamping grooves 120 are provided on the limiting rod 12. The oil pipe clamping grooves 120 are used to clamp the oil pipe 3 along the circumferential direction of the oil pipe 3. The plurality of oil pipe clamping grooves 120 are arranged at intervals along the axial direction of the limiting rod 12. There are a plurality of limiting rods 12, and the plurality of limiting rods 12 are arranged at intervals along the width direction of the box body 10. The setting of the limiting rod 12 is used to divide the internal space of the box body 10, so that the oil pipes 3 are arranged in an array. The oil pipe clamping grooves 120 are used to fix the position of the oil pipe 3 in the box body 10 and prevent the oil pipes 3 from colliding with each other and causing damage.

[0049] In an exemplary embodiment of the present application, the length direction of the box body 10 is the direction parallel to the horizontal plane and parallel to the plane formed by the pipe feeding hole 100 and the pipe grasping device 2. The width direction of the box body 10 is the direction perpendicular to the plane formed by the pipe feeding hole 100 and the pipe grasping device 2. The extension of the limiting rod 12 along the length direction of the box body 10 can enable the oil pipe 3 to reach any space inside the box body 10 without obstruction after entering the box body 10 from the pipe feeding hole 100.

[0050] Furthermore, at least two layers of oil pipe installation layers are arranged at intervals along the height direction of the box body 10. Each oil pipe installation layer includes a plurality of limiting rods 12 arranged at intervals along the width direction of the box body 10, and the limiting rods 12 in the same oil pipe installation layer are all in the same plane. The limiting rods 12 corresponding to each other along the height direction of the box body 10 together form an oil pipe installation position. The height direction of the box body 10 is the direction perpendicular to the horizontal plane. The setting of multiple layers of oil pipe installation layers can enable each oil pipe installation position to firmly and stably place the oil pipe 3, avoid the oil pipes 3 from being disorderly and crossed inside the box body 10 and colliding, and improve the stability and safety of the box body 10.

[0051] Specifically, the oil pipe 3 located at the oil pipe installation position is arranged at an angle with the vertical direction. The angle between the oil pipe 3 located at the oil pipe installation position and the vertical direction is A. Preferably, 1.5° ≤ A ≤ 2°. Since there is a certain horizontal offset between the upper and lower parts of the storage array inside the box body 10 of the oil pipe storage box 1, the arrangement of the oil pipe 3 located at the oil pipe installation position at an angle with the vertical direction can achieve inclined vertical temporary storage by relying on gravity. The selection of the angle A satisfying 1.5° ≤ A ≤ 2° can maximize the utilization efficiency of the internal space of the box body 10 while adjusting the horizontal offset of the upper and lower parts of the storage array.

[0052] Furthermore, the oil pipe storage box 1 further includes an in-box pipe grasping mechanism 13. The in-box pipe grasping mechanism 13 includes at least one gripper 131 and a gripper fixing frame 132. The gripper 131 is connected to the gripper fixing frame 132.

The gripper fixing frame 132 is movably arranged inside the box body 10 to transport the oil pipe 3 to any one of the oil pipe installation positions. Through the setting of the in-box pipe grasping mechanism 13, the oil pipe 3 can move freely inside the box body 10, and the grasped oil pipe 3 can be placed at a preset position.

[0053] In an exemplary embodiment of the present application, the gripper fixing frame 132 is a gripper fixing rod extending along the height direction of the box body 10. The gripper 131 is slidably connected to the gripper fixing rod to adjust the height of the gripper 131. The rod-shaped structure of the gripper fixing rod ensures the stable connection of the gripper 131 during the movement of the gripper 131 along the gripper fixing rod, improving the operation stability. Preferably, two grippers 131 are provided to make the grasping and moving of the oil pipe 3 more stable.

The gripper fixing rod slides along the track assembly 14 to transport the oil pipe 3 to any one of the oil pipe installation positions. The setting of the track assembly 14 provides support for the movement of the gripper fixing rod inside the box body 10. The connection of the two track assemblies 14 to the gripper fixing rod shares the operation force of the gripper 131 from both ends of the box body 10, improving the movement operation stability of the gripper fixing rod.

[0055] Specifically, the rail assembly 14 includes a first guide rail 141 and a second guide rail 142.

Through the communicative arrangement of the first guide rail 141 and the second guide rail 142, the gripper fixing rod can move arbitrarily inside the box body 10, driving the gripper 131 to place the oil pipe 3 in any oil pipe slot 120.

[0056] Optionally, the first guide rail 141 and the second guide rail 142 are slidably arranged relative to each other. It includes a scheme where the first guide rail 141 can slide along the second guide rail 142, a scheme where the second guide rail 142 can slide along the first guide rail 141, and a scheme where both the first guide rail 141 and the second guide rail 142 can slide relative to each other along another guide rail.

[0057] In an embodiment of the present application, there is one second guide rail 142 and two first guide rails 141.
