[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Referring to Figures 1, 4, 5, and 6, a quick connection and sealing device for oil and gas pipelines includes a fixed plate 1. A clamping mechanism and an adjusting mechanism are fixed on the fixed plate 1. Two arc-shaped support plates 12 are fixed on the adjusting mechanism. The adjusting mechanism includes a linear motor 10, which is fixed to the fixed plate 1. A connecting frame 11 is fixed to the slider of the linear motor 10. Both support plates 12 are fixed to the connecting frame 11. With the assistance of the linear motor 10, the movement of the two support plates 12 can be adjusted, facilitating the adjustment of their positions. Multiple guide wheels 13 are equidistantly fixed on each support plate 12. The arrangement of the multiple guide wheels 13 facilitates the adjustment of the support plates. The lifting oil and gas pipelines placed on the pallet 12 are moved with assistance, making it easier for them to move. Two connecting mechanisms are symmetrically fixed on the pallet 12 near the clamping mechanism. A cylinder 17 is fixed on both connecting mechanisms. A sealing rubber ring 18 is coaxially fixed on the inner wall of the cylinder 17. With the assistance of the cylinder 17 and the sealing rubber ring 18, the sealing between the two oil and gas pipelines can be ensured when they are spliced. After the two oil and gas pipelines are installed on the cylinder 17, the cylinder 17 is welded to the two oil and gas pipelines to further ensure the sealing between them.

[0023] The two support plates 12 are arc-shaped and are coaxially arranged with the cylinder 17. When the two oil and gas pipelines are spliced, they can be quickly aligned. The connecting mechanism includes a connecting rod 14, one end of which is fixed to the support plate 12 and the other end is fixed to an electromagnet 15. A fixing block 16 is magnetically fixed to the electromagnet 15 and fixed to the cylinder 17. The electromagnet 15 and the linear motor 10 are both connected to a battery through wires. The battery powers the electromagnet 15 and the linear motor 10. After the two oil and gas pipelines are inserted into the cylinder 17 and installed, the two electromagnets 15 are de-energized. When the two support plates 12 need to be removed from the oil and gas pipelines, the two electromagnets 15 can keep the cylinder 17 in its original position as it is removed.

[0024] In use, the clamping mechanism is clamped onto the fixed oil and gas pipeline. At this time, the axes of the two support plates 12 are coaxial with the fixed oil and gas pipeline. With the assistance of the linear motor 10, the cylinder 17 is fitted onto the fixed oil and gas pipeline. The hoisted oil and gas pipeline is placed on the two support plates 12. With the assistance of multiple guide wheels 13, it is easy to push the hoisted oil and gas pipeline to move, so that the hoisted oil and gas pipeline is also inserted into the cylinder 17. The two oil and gas pipelines contact the sealing rubber ring 18. While quickly and accurately connecting the two oil and gas pipelines together, it can also ensure the sealing between the two oil and gas pipelines.

[0025] Example 2: Based on Example 1, referring to Figures 1-5, as another preferred embodiment of this utility model, the difference from Example 1 is that the clamping mechanism includes a first clamping plate 2 and a second clamping plate 3. The first clamping plate 2 is fixed on the fixed plate 1. Both the first clamping plate 2 and the second clamping plate 3 are arc-shaped structures, and the two support plates 12, the cylinder 17, the first clamping plate 2 and the second clamping plate 3 are all coaxially arranged, so that the two pipes can be quickly aligned coaxially when splicing. Two clamping components are symmetrically fixed on the first clamping plate 2 and the second clamping plate 3.

[0026] The clamping assembly includes two edge plates 4, which are respectively fixed on the first clamping plate 2 and the second clamping plate 3. An insert rod 6 is provided through the first clamping plate 2 and the second clamping plate 3. A baffle 5 is fixed on one end of the insert rod 6, and a positioning assembly is provided on the other end together with the edge plate 4. The positioning assembly includes a groove 7 and a rotating shaft 9. The groove 7 is provided on the insert rod 6, and the rotating shaft 9 is fixed on the edge plate 4. A limiting rod 8 is rotatably provided on the rotating shaft 9. The limiting rod 8 is inserted into the groove 7. The limiting rod 8 is made of a self-lubricating rod. When the limiting rod 8 is made of a self-lubricating rod, it can reduce the friction with the inner wall of the groove 7, so that the limiting rod 8 rotates more smoothly.

[0027] In use, the first clamping plate 2 and the second clamping plate 3 are clamped onto the fixed oil and gas pipeline. The two limiting rods 8 are rotated to the two grooves 7, thereby clamping and limiting the first clamping plate 2 and the second clamping plate 3 onto the fixed oil and gas pipeline. At this time, the fixing plate 1 is directly below the fixed oil and gas pipeline, and the height of the two support plates 12 is fixed along with the fixing plate 1. This makes it very convenient to install or remove the first clamping plate 2 and the second clamping plate 3 on the fixed oil and gas pipeline.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
