Description

Technical Field

[0001] This utility model relates to the field of oil pipeline technology, and more specifically, it relates to a conveying and docking device for welding and assembling oil pipelines. Background Technology

[0002] Nowadays, most oil pipelines are joined by welding. To ensure the flatness of the connection surface during welding, a docking auxiliary device is needed to connect the two sections of oil pipeline. Then, the connection between the two sections of oil pipeline is made by welding to complete the assembly of the oil pipeline.

[0003] Patent CN222944875U discloses a docking device for oil pipeline installation. The device can clamp and fix pipelines of different sizes through the setting of clamping components, which improves the practicality of the device. In addition, the device can transport the pipeline to be docked to the right through the setting of driving components, which saves a lot of labor and improves work efficiency. Furthermore, the height of the second rotating wheel in the middle is consistent with the height of the inner bottom side of the two sets of first fixing seats, ensuring that the height of the two sets of pipelines is consistent during the welding process, which facilitates subsequent welding.

[0004] While the aforementioned device can transport oil pipes and connect two sections of oil pipe, the oil pipes cannot rotate to facilitate welding during the subsequent welding process. This results in uneven weld seams at the pipe joints, reducing the overall strength of the assembled oil pipe connection. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a conveying and docking device for oil pipe welding assembly that can transport two sections of oil pipe for docking and drive the oil pipe to rotate and cooperate in welding during the subsequent welding process, thereby improving the connection strength of the oil pipe joint after assembly.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A conveying and docking device for welding and assembling oil pipes includes an installation platform, a rotating mechanism installed in the middle of the installation platform, a limiting mechanism, and conveying mechanisms installed on both sides of the installation platform. The installation platform includes interconnected installation beams and installation plates connected to the installation beams. The conveying mechanism includes a linear slide rail installed on the installation plate, a sliding plate connected to the linear slide rail, a main conveying assembly located in the middle of the sliding plate, and side conveying assemblies located on both sides of the main conveying assembly. The rotating mechanism includes a fixed plate installed at the bottom of the installation beams, rotating frames symmetrically arranged on the fixed plate, and rotating wheels rotatably installed on the rotating frames.

[0008] The present invention is further configured such that: multiple mounting beams are connected to form a frame structure, and the two sides of the mounting plate are respectively connected to the mounting beams.

[0009] The present invention is further configured such that: the side conveying assembly includes a side fixing frame mounted on a sliding plate, a side conveying wheel rotatably mounted on the side fixing frame, and a side connecting frame disposed between the side conveying wheel and the side fixing frame, wherein a side buffer spring is provided at the bottom of the side connecting frame.

[0010] The present invention is further configured such that: the main conveying assembly includes a main fixed frame mounted on a sliding plate and a main conveying wheel rotatably mounted on the main fixed frame; a main connecting frame is connected between the main conveying wheel and the main fixed frame; and the bottom of the main connecting frame abuts against the sliding plate.

[0011] The present invention is further configured such that: the rotating mechanism includes a mounting frame and a drive motor mounted on the mounting frame, the output end of the drive motor is connected to an output wheel, an auxiliary frame is mounted on the bottom of the fixed plate, and an auxiliary wheel is rotatably mounted on the auxiliary frame.

[0012] The present invention is further configured such that: a belt is fitted on the output wheel, and the belt is connected to the rotating wheel and the auxiliary wheel respectively.

[0013] By adopting the above technical solution, the drive motor drives the output wheel to rotate, and the belt drives the two rotating wheels and the auxiliary wheel to rotate respectively. The auxiliary wheel is used to tension the belt to ensure the normal rotation of the rotating wheels. When the oil pipe is placed between the two rotating wheels, the rotation of the two rotating wheels can drive the oil pipe to rotate synchronously, thereby cooperating to perform welding.

[0014] The present invention is further configured such that: the limiting mechanism is symmetrically arranged about the rotating mechanism, and the limiting mechanism includes a base mounted on the mounting beam, a side frame rotatably connected to the base, and a limiting wheel rotatably mounted on the side frame.

[0015] The present invention is further configured such that: the side frame is inclined, a connecting rod is provided at the connection between the side frame and the base, a torsion spring is sleeved on the connecting rod, one end of the torsion spring abuts against the top of the base, and the other end of the torsion spring abuts against the bottom of the side frame.

[0016] The beneficial effects of this utility model are:

[0017] The sliding plate is moved by the linear slide rail, so that the two oil pipes are placed on the rotating wheel to complete the docking. After docking, the rotation of the two rotating wheels drives the oil pipes to rotate synchronously, so that the oil pipes cooperate to weld the oil pipe joint during the rotation process, ensuring that the weld at the joint is uniform and improving the connection strength of the oil pipes after assembly.

[0031] Please refer to Figure 1 A conveying and docking device for welding and assembling oil pipes includes an installation platform 1, a rotating mechanism 3 installed in the middle of the installation platform 1, a limiting mechanism 4, and conveying mechanisms 2 installed on both sides of the installation platform 1. Two sections of oil pipe are placed on the conveying mechanisms 2 on both sides, and the conveying mechanisms 2 transport the two sections of oil pipe to the rotating mechanism 3 to complete the docking. During the welding process, the rotating mechanism 3 drives the oil pipe to rotate to cooperate with the welding, ensuring that the weld at the oil pipe joint is uniform.

[0032] Please refer to Figure 1-2 The mounting platform 1 includes interconnected mounting beams 11 and mounting plates 12 connected to the mounting beams 11. Multiple mounting beams 11 are connected to form a frame structure. A rotating mechanism 3 is installed in the middle of the two top mounting beams 11, and mounting plates 12 are symmetrically arranged on both sides of the rotating mechanism 3. The mounting plates 12 are connected to the side walls of the vertically arranged mounting beams 11 on both sides, and the height of the mounting plates 12 is lower than the height of the two top mounting beams 11.

[0033] Please refer to Figure 1-2 and Figure 6The conveying mechanism 2 includes a linear slide rail 21 mounted on a mounting plate 12, a sliding plate 22 connected to the linear slide rail 21, a main conveying assembly 24 disposed in the middle of the sliding plate 22, and side conveying assemblies 23 disposed on both sides of the main conveying assembly 24. The linear slide rail 21 is symmetrically arranged along the axis of the mounting plate 12. Two sliding plates 22 are mounted on the top of the linear slide rail 21. The linear slide rail 21 can drive the sliding plates 22 to move along the length direction of the linear slide rail 21. The linear slide rail 21 and the sliding plate 22 are built-in drive linear guide rail structures in the prior art, and the specific internal structure will not be described in detail in this application. The side conveying assembly 23 includes a side fixing frame 231 mounted on the sliding plate 22, a side conveying wheel 235 rotatably mounted on the side fixing frame 231, and a side connecting frame 232 disposed between the side conveying wheel 235 and the side fixing frame 231. The side fixing frame 231 is arranged perpendicular to the sliding plate 22, and the side conveying wheel 235 is rotatably mounted between the two side fixing frames 231. The side connecting frame 232 is connected to the side fixed frame 231. The side fixed frame 231 has a U-shaped groove, and the side connecting frame 232 can slide along the U-shaped groove. The side conveying wheel 235 is rotatably connected to the side connecting frame 232. A side connecting rod 233 is connected to the bottom of the side connecting frame 232. The side connecting rod 233 is fixedly connected to the bottom of the side connecting frame 232 and slides downward to the sliding plate 22, passing through the sliding plate 22. A side buffer spring 234 is provided at the bottom of the side connecting frame 232. The side buffer spring 234 is sleeved between the side connecting frame 232 and the sliding plate 22. When the side conveying wheel 235 is pressed, the pressure can be transmitted to the side buffer spring 234 for buffering through the sliding of the side connecting frame 232. The main conveying assembly 24 includes a main fixed frame 241 mounted on the sliding plate 22 and a main conveying wheel 243 rotatably mounted on the main fixed frame 241. The main fixed frame 241 is vertically mounted in the middle of the sliding plate 22, and the main conveying wheel 243 is rotatably mounted between the two main fixed frames 241. A main connecting frame 242 is connected between the main conveying wheel 243 and the main fixed frame 241. The main connecting frame 242 is fixedly connected to the main fixed frame 241, and the bottom of the main connecting frame 242 abuts against the sliding plate 22.

[0034] Please refer to Figure 1-5The rotating mechanism 3 includes a fixed plate 35 mounted on the bottom of the mounting beam 11, rotating frames 36 symmetrically arranged on the fixed plate 35, and rotating wheels 37 rotatably mounted on the rotating frames 36. The fixed plate 35 is connected to two top mounting beams 11 on both sides. The rotating frames 36 are symmetrically arranged along the fixed plate 35, and each of the two rotating frames 36 has a rotating wheel 37 mounted on it. One end of each rotating wheel 37 is connected to a pulley. The rotating mechanism 3 also includes a mounting frame 31 and a drive motor 32 mounted on the mounting frame 31. The mounting frame 31 is installed inside the frame structure formed by the mounting beams 11. The output end of the drive motor 32 is connected to an output wheel 33, which can drive the output wheel 33 to rotate. An auxiliary frame 39 is mounted on the bottom of the fixed plate 35, and an auxiliary wheel 38 is rotatably mounted on the auxiliary frame 39. The auxiliary wheel 38 is located between the two rotating wheels 37 and below them. A belt 34 is fitted onto the output wheel 33, and the belt 34 is connected to the pulley at the end of the rotating wheel 37 and the auxiliary wheel 38, respectively. After the drive motor 32 drives the output wheel 33 to rotate, the belt 34 drives the pulleys and auxiliary wheel 38 at the ends of the two rotating wheels 37 to rotate. The auxiliary wheel 38 is used to tension the belt 34 to ensure the normal rotation of the rotating wheels 37. When the oil pipe is placed between the two rotating wheels 37, the rotation of the two rotating wheels 37 can drive the oil pipe to rotate synchronously, thereby cooperating to perform welding.

[0035] Please refer to Figure 1-5 and Figure 7 The limiting mechanism 4 is symmetrically arranged about the rotating mechanism 3. The limiting mechanism 4 includes a base 41 mounted on the mounting beam 11, a side frame 42 rotatably connected to the base 41, and a limiting wheel 45 rotatably mounted on the side frame 42. The base 41 is respectively mounted on both sides of the rotating mechanism 3. A connecting rod 43 is provided at the connection between the side frame 42 and the base 41. The side frame 42 and the connecting rod 43 are fixedly connected. The connecting rod 43 is rotatably mounted on the base 41, and its two ends are respectively provided through the base 41 to strengthen the connection between the base 41 and the side frame 42. A torsion spring 44 is sleeved on the connecting rod 43. One end of the torsion spring 44 abuts against the top of the base 41, and the other end of the torsion spring 44 abuts against the bottom of the side frame 42. When the torsion spring 44 is in the relaxed state, the side frame 42 is tilted towards the center of the rotating mechanism 3. The limiting wheel 45 is offset from the two rotating wheels 37. When the oil pipe is placed between the two rotating wheels 37, the limiting wheel 45 at the end of the side frame 42 can press the oil pipe downward through the pressure generated by the torsion spring 44, thereby abutting against the side wall of the oil pipe and limiting its movement. At the same time, it can also assist the oil pipe in rotating synchronously through the rotation of the limiting wheel 45. When it is necessary to loosen the limiting wheel 45's restriction on the oil pipe, the side frame 42 can be rotated to compress the torsion spring 44, causing the side frame 42 to tilt away from the center of the rotating mechanism 3, making it easier to remove the oil pipe.

[0036] Specifically, two oil pipes are placed on the conveying mechanisms 2 on both sides of the rotating mechanism 3. At this time, the side walls of the oil pipes abut against the side conveying wheels 235 on the two side conveying components 23, and the bottom of the oil pipes abuts against the main conveying wheel 243 on the main conveying component 24. The pressure from the oil pipes on the side conveying wheels 235 is transmitted to the side buffer springs 234 for buffering through the side connecting frame 232. The linear slide rail 21 can drive the sliding plate 22 to move, so that the two oil pipes are connected. At this time, the oil pipe connection is located inside the rotating mechanism 3, and the limiting wheel 45 abuts against the side wall of the oil pipe to limit the oil pipe.

[0037] After the docking is completed, during the welding process, the drive motor 32 drives the output wheel 33 to rotate, and the belt 34 drives the two rotating wheels 37 and the auxiliary wheel 38 to rotate respectively. The rotation of the two rotating wheels 37 can synchronously drive the oil pipe to rotate. During the rotation of the oil pipe, the limit wheel 45, the main conveying wheel 243 and the side conveying wheel 235 can be driven to rotate at the same time, and the oil pipe can be rotated to assist in the welding.

[0038] The linear slide rail 21 drives the sliding plate 22 to move, so that the two oil pipes are placed on the rotating wheel 37 to complete the docking. After docking, the rotation of the two rotating wheels 37 drives the oil pipes to rotate synchronously, so that the oil pipes cooperate to weld the oil pipe joint during the rotation process, ensuring that the weld at the joint is uniform and improving the connection strength of the oil pipes after assembly.
