Description

Technical Field

[0001] The utility model relates to the technical field of pipeline installation, in particular to a pipeline connection docking device. Background Art

[0002] Oil pipeline installation refers to the installation of a pipeline system underground or underwater for the transportation of oil and oil products. This installation process involves steps such as selecting appropriate pipe materials, laying out and connecting the pipes, and conducting necessary tests and inspections. Through oil pipeline installation, oil can be transported over long distances to meet energy needs.

[0003] At present, most oil pipeline installations use hoisting connections. However, since there is only one fulcrum during hoisting, the pipeline is prone to shaking, which requires multiple position adjustments during docking. The docking operation is cumbersome and can easily lead to unbalanced force on the pipeline and a lot of residual internal stress, causing the risk of oil pipeline rupture. Utility Model Content

[0017] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0018] See also Figure 1 to Figure 5 A pipe connection device comprises a base 1, on which a supporting structure and two lifting structures respectively located at two ends of the supporting structure are arranged.

[0019] The supporting structure is provided with an arc-shaped support plate 21 that matches the pipeline, and horizontal flanges 22 are provided on both sides of the arc-shaped support plate 21. The horizontal flanges 22 are supported by shock absorbers 23. The arc-shaped support plate 21 is supported by an arc-shaped slide rail 24, and the arc-shaped slide rail 24 is installed on a support frame 25. The two are slidably matched, and the support frame 25 and the shock absorber 23 are fixed on the base 1.

[0020] The lifting structure is provided with an arc-shaped lifting plate 31 that matches the pipeline. The arc-shaped lifting plate 31 is supported by a bracket 32. The bracket 32 ​​is placed on the base 1. A lifting screw 33 is provided below the arc-shaped lifting plate 31. A driven gear 34 threadedly connected to the lifting screw 33 is provided on the lifting screw 33. The driven gear 34 is installed in a fixing ring 35, and the two are rotatably connected. The fixing ring 35 is fixed on the base 1. The driven gear 34 is meshed with a driving gear 36. The driving gear 36 is driven by a motor 37, and the motor 37 is fixed on the base 1.

[0021] When in use, the two butted pipe sections are hoisted onto the arc-shaped support plate, and the force is transmitted to the arc-shaped slide rail through the arc-shaped support plate. The arc-shaped slide rail slides under the force until the two pipe sections are in a force balance state, which can reduce the stress generated in the pipeline; the height of the pipe section is adjusted by using the lifting structure, so that the two pipe sections are coaxial. The lifting structure adopts a gear set to drive the spiral transmission mechanism to achieve lifting, which has a simple structure, convenient operation and high efficiency.

[0022] In this embodiment, each horizontal flange 22 is supported by three shock absorbers 23. There are two arc-shaped slide rails 24, which are arranged symmetrically on the left and right. There are two lifting screws 33, which are arranged symmetrically on the front and back.

[0023] Use of this utility model:

[0024] The two butt-jointed pipe sections are placed on the arc-shaped support plate 21 by a crane. The arc-shaped support plate 21 is subjected to downward pressure, which is transmitted to the shock absorber 23 and the arc-shaped slide rail 24. The arc-shaped slide rail 24 slides until the pipe sections are balanced in force, thereby reducing the generation of internal stress.

[0025] Then the motor 37 is started to adjust the top height of the lifting screw rod 33 until the two butt-jointed pipe sections are aligned.

[0026] Although the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive.
