Description

Technical Field

[0001] This utility model relates to the field of pipeline handling technology, and in particular to a pipeline lifting device and pipeline handling equipment. Background Technology

[0002] In the workplace, traditional pipeline handling (including lifting and transportation) mainly relies on manual labor and hydraulic forklifts. Manual handling has the following disadvantages:

[0003] (1) High labor intensity: For pipelines that are heavy and long, the physical requirements for workers are extremely high, and long-term work can easily lead to fatigue and injury.

[0004] (2) Low handling efficiency: Compared with mechanized handling, manual handling is slower and less efficient, which affects the progress of the project.

[0005] (3) Poor safety: During the handling process, personnel may cause safety accidents such as pipeline falling or collision due to physical exhaustion or improper operation.

[0006] However, hydraulic forklifts have the following disadvantages in handling:

[0007] (1) High equipment costs: Forklifts and other mechanical equipment are expensive and require regular maintenance and upkeep, which increases operating costs;

[0008] (2) Limited flexibility: In narrow or complex terrain, forklifts occupy a large area and are inconvenient to turn, which affects the efficiency of handling.

[0009] (3) Poor stability: Hydraulic forklifts lack a curved surface fixed structure, and pipelines are prone to tipping over or rolling on the forklift, which can easily lead to safety accidents. Utility Model Content

[0010] The technical problem to be solved by this utility model is to provide a pipeline lifting device and pipeline handling equipment, addressing at least one defect of the related technologies mentioned in the background: manual pipeline lifting suffers from high labor intensity, low efficiency and poor safety.

[0013] At least one tube carrier groove has two ports along its length and is rotatably connected to the top of the main body for adjusting the orientation of the two ports by rotation; the tube carrier groove has a slot along its depth and the slot is oriented opposite to the main body.

[0014] A moving mechanism, rotatably connected to both sides of the main body mechanism; and,

[0015] A steering mechanism is connected to the main body and extends away from the main body. The vertical distance from the end of the steering mechanism to the moving mechanism is greater than the vertical distance from the end of the carrying tube groove to the moving mechanism.

[0016] In some embodiments, the carrier groove is arc-shaped.

[0017] In some embodiments, the opening of the carrier tube groove is 300-450 mm.

[0018] In some embodiments, the carrier tube is a sheet made of a rigid material.

[0020] Alternatively, the lengths from the two ends of the carrier tube to the rotating connection are not equal.

[0021] In some embodiments, the steering mechanism is a long, curved rod that extends in a direction away from the main body.

For example, they can refer to fixed connections or detachable connections, mechanical connections or chemical connections, direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] On offshore oil platforms, pipeline lifting and transportation is a demanding and high-risk task. Because the platforms are far from land, the working space is limited, and large, precision lifting and transportation equipment is scarce, traditional manual lifting methods are labor-intensive, inefficient, and unsafe. Therefore, if... Figure 1 As shown, some embodiments of this utility model disclose a pipeline lifting device, including a main body mechanism 1, at least one pipe-carrying groove 2, a moving mechanism 3, and a steering mechanism 4. It can be understood that at least one can be one, two, three, or any number, as detailed below:

[0039] The tube carrier 2 has two ports 21 along its length L. The tube carrier 2 is rotatably connected to the top of the main body 1, and is used to adjust the orientation of the two ports 21 by rotation. Figure 2 As shown. The pipe-carrying groove 2 has a slot 22 in the depth direction D, and the slot 22 faces away from the main body mechanism 1. The moving mechanism 3 is rotatably connected to both sides of the main body mechanism 1. The steering mechanism 4 is connected to the main body mechanism 1 and is used to change the orientation of the pipeline lifting device. The steering mechanism 4 extends away from the main body mechanism 1, and the vertical distance from the end of the steering mechanism 4 to the moving mechanism 3 is greater than the vertical distance from the end of the pipe-carrying groove 2 to the moving mechanism 3; that is, the steering mechanism 4 is a long arm, and the pipe-carrying groove 2 is a short arm.

[0040] It should be noted that the pipeline lifting device is used to assist in the lifting (i.e., grabbing and lifting) of pipelines during the pipeline handling process. Understandably, when there are at least two pipe-carrying tanks 2, the pipeline lifting device can also be directly used for the lifting and transportation of short pipelines.

[0041] In this embodiment, the pipe-carrying groove 2 of the pipeline lifting device can rotate 360°. This rotation adjusts the orientation of the two ports 21 to accommodate pipelines placed in different directions, enabling multi-degree-of-freedom lifting of pipelines and improving lifting flexibility and adaptability. The curved surface of the pipe-carrying groove 2 effectively prevents pipelines from tipping over, rolling, slipping, or being damaged during lifting, enhancing safety. This pipeline lifting device employs a mechanized lifting method. In practical use, the steering mechanism 4 acts as the power arm, the pipe-carrying groove 2 as the resistance arm, and the moving mechanism 3 as the fulcrum. Utilizing the lever principle, it can easily lift heavy and bulky pipelines, effectively reducing the labor intensity of operators, improving work efficiency, and avoiding complex and expensive hydraulic or mechanical devices, resulting in low equipment cost. This pipeline lifting device has a simple structure and high flexibility, making it suitable for work sites with limited space resources, such as offshore oil platforms and narrow passageways. It can move freely in the limited and complex space of offshore oil platforms, easily handling narrow passageways, crowded equipment rooms, and uneven decks, greatly improving work efficiency.

[0042] In practical use, the operator operates the steering mechanism 4 according to the orientation of the placed pipeline, so that the direction of the connecting line on both sides of the main body mechanism 1 is consistent with the orientation of the pipeline. The operator then rotates the pipe carrier 2 so that the orientation of the two ends 21 of the pipe carrier 2 is consistent with the orientation of the pipeline, i.e. Figure 2 As shown, the operator then lifts the steering mechanism 4. At this time, the pipe-carrying groove 2 is tilted and the groove opening 22 is aligned with the pipeline. After the operator operates the steering mechanism 4 to push it forward, the pipe-carrying groove 2 fits against the bottom of the pipeline. Using the moving mechanism 3 as the lifting fulcrum, the operator lowers the steering mechanism 4 to make the pipe-carrying groove 2 tilt the pipeline. The pipeline is accommodated in the pipe-carrying groove 2, thereby realizing the lifting of the pipeline. At the same time, the pipe-carrying groove 2 can well support the pipeline.

[0043] In some embodiments, such as Figure 1 and Figure 2 As shown, the carrier groove 2 is arc-shaped, such as a semi-circular shape. The circular shape here is just an example and is not intended to limit this application. It can also be other shapes.

[0044] In some embodiments, such as Figure 1 and Figure 2As shown, the opening 22 of the slot 2 of the carrier tube 2 is 300-450mm, preferably 450mm. The 450mm here is just an example and is not intended to limit this application. Other sizes are also possible.

[0045] In some embodiments, such as Figure 1 and Figure 2 As shown, the carrier tube 2 is a sheet made of a rigid material, such as metal, aluminum alloy, copper, etc. The metal here is just an example and is not intended to limit this application; it can also be other materials.

[0046] In some embodiments, such as Figure 1 and Figure 2 As shown, the two ends of the carrier tube 2 have the same length and shape from the rotating connection. In some other embodiments, the two ends of the carrier tube 2 have different lengths from the rotating connection.

[0047] In some embodiments, such as Figure 1 and Figure 2 As shown, the steering mechanism 4 is a long strip rod that extends or bends away from the main mechanism 1. The longer the rod, the easier it is to lift the pipeline using the leverage effect. Of course, a longer rod is not necessarily better.

[0048] In some embodiments, such as Figure 3 As shown, in order to achieve 360° rotation of the pipe-carrying tank 2, the pipeline lifting device also includes a bearing 5. The bottom of the pipe-carrying tank 2 is provided with a connecting shaft 23, and the top of the main body mechanism 1 is provided with a bearing column 11. The outer ring of the bearing 5 is fixed in the bearing column 11, and the connecting shaft 23 is inserted into the inner ring of the bearing 5. The connecting shaft 23 can rotate freely around the bearing 5.

[0049] In some embodiments, the moving mechanism 3 is a swivel wheel or a directional wheel, and the number of wheels on each side of the main body mechanism 1 is at least one. Understandably, at least one can be one, two, three or any number.

[0050] In some embodiments, such as Figure 4 As shown, in order to avoid wear or damage to the pipeline during lifting or transportation, the inner surface of the pipe-carrying groove 2 is provided with a buffer layer 24, such as a rubber layer. The rubber layer here is just an example and is not intended to limit this application. Other types are also possible.

[0051] In other embodiments, such as Figure 5As shown, in order to avoid wear or damage to the pipeline during lifting or transportation, and to make the pipe-carrying groove 2 adapt to pipelines of different sizes, so that the pipe-carrying groove 2 fits the pipeline that needs to be lifted more closely and prevents the pipeline from shaking, the inner surface of the pipe-carrying groove 2 is provided with at least two elastic support members 25 along its radial direction. It can be understood that at least two can be two, three or any number. The elastic support member 25 includes a support surface and an elastic element that fixes the support surface and the inner surface of the pipe-carrying groove 2. For example, the elastic element is a spring. The spring here is only an example and is not intended to limit this application. Other elements may also be used.

[0052] In some embodiments, such as Figure 4 and Figure 5 As shown, when the pipeline is housed in the pipeline carrier 2, in order to further avoid problems such as the pipeline falling during transportation, the outer surfaces of the two ends of the pipeline carrier 2 are respectively provided with outward-extending "T"-shaped connectors 26 for binding straps to secure the pipeline in the pipeline carrier 2.

[0053] In some other embodiments, one end of the carrier tube groove 2 is connected to a locking groove (not shown) via a shaft. The locking groove is also arc-shaped and is a sheet made of rigid material. The locking groove and the other end of the carrier tube groove 2 are detachably connected, for example, by a snap-fit ​​connection. The snap-fit ​​connection here is only an example and is not intended to limit this application. Other connections are also possible.

[0054] Some embodiments of this utility model disclose a pipeline handling device, including at least two pipeline lifting devices as described in any of the above embodiments. The two pipeline lifting devices lift both ends of the pipeline. When an operator pushes or pulls the steering mechanism 4 of the pipeline lifting device, the pipeline can be transported. It is understood that "at least two" can be two, three, or any number. For example, when four pipeline lifting devices are included, two are located at both ends of the pipeline, and the other two are located between the two ends of the pipeline.

[0055] In this embodiment of the pipeline handling equipment, the pipe-carrying groove 2 of the pipeline lifting device can rotate 360°. This rotation adjusts the orientation of the two ports 21 to accommodate pipelines placed in different directions, enabling multi-degree-of-freedom lifting and transportation of pipelines, thus improving the flexibility and adaptability of lifting and transportation. The pipe-carrying groove 2 of this pipeline lifting device has a curved surface, effectively preventing pipelines from tipping over, rolling, slipping, or being damaged during lifting and transportation, enhancing the safety of the lifting and transportation process. This pipeline lifting device adopts a mechanized lifting and transportation method. In practical use, the steering mechanism 4 can act as a power arm, the pipe-carrying groove 2 as a resistance arm, and the moving mechanism 3 as a fulcrum. Utilizing the lever principle, it can easily lift heavy and large pipelines, effectively reducing the labor intensity of operators, improving work efficiency, and avoiding complex and expensive hydraulic or mechanical devices, resulting in low equipment cost. This pipeline lifting device has a simple structure and high flexibility, making it suitable for work sites with limited space resources, such as offshore oil platforms and narrow passageways. It can move freely in the limited and complex space of offshore oil platforms, easily handling narrow passageways, crowded equipment rooms, and uneven decks, greatly improving work efficiency.

[0056] It is understood that the above embodiments only illustrate some implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can freely combine the above embodiments or technical features without departing from the concept of this utility model, and can also make several modifications and improvements, all of which fall within the protection scope of this utility model. That is, the embodiments described "in some embodiments" can be freely combined with any of the preceding and following embodiments.
