[0003] While this device reduces labor intensity, it has significant shortcomings: First, it relies on precision electrical and transmission components such as motors and lead screws, resulting in a complex structure. In the harsh environment of oilfields, characterized by dust, humidity, and explosiveness, it suffers from a high failure rate, is difficult to maintain, and poses safety hazards. Second, the electric drive method is severely limited in field operations where there is no electricity or the power supply is unstable. Furthermore, its clamps are usually of fixed size, making it difficult for one set of devices to adapt to pipes of different diameters, resulting in poor versatility.

[0004] Therefore, it is necessary to provide a new pipeline connection device for oil extraction to solve the above-mentioned technical problems. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1 , Figure 2 and Figure 3,in, Figure 1 This is a schematic diagram of the structure of this utility model;

[0021] Figure 2 This is a schematic diagram of the convex slider in this utility model; Figure 3 This is a schematic diagram of the clamping and positioning mechanism in this utility model. It includes: a U-shaped base 1, a docking mechanism, and a clamping and positioning mechanism.

[0022] refer to Figure 1 and Figure 3 As shown, a docking mechanism is connected to the U-shaped base 1. The docking mechanism includes a sliding rod 3, a convex slider 5, and a locking bolt 6. Two parallel sliding rods 3 are fixedly connected inside the U-shaped base 1. Two parallel convex sliders 5 are provided inside the U-shaped base 1. The convex sliders 5 are slidably sleeved on the two sliding rods 3. Two symmetrically arranged locking bolts 6 are threaded onto the convex sliders 5. Two parallel anti-retraction grooves 4 are formed on the upper surface of the U-shaped base 1. The lower inner surface of the anti-retraction grooves 4 is provided with anti-slip texture. The lower end of the locking bolt 6 abuts against the lower inner surface of the anti-retraction groove 4. The convex slider 5 is connected to a clamping and positioning mechanism, which includes a V-shaped block 7, an arc plate 9, a fixed plate 10, and a fixing bolt 11. A matching V-shaped block 7 is fixedly connected to the upper surface of the convex slider 5. A matching arc plate 9 is provided above the V-shaped block 7. Fixed plates 10 are fixedly connected to both sides of the arc plate 9. Two symmetrically arranged fixing bolts 11 are threadedly connected to the fixed plate 10. A threaded hole matching the fixing bolt 11 is opened on the upper surface of the V-shaped block 7. The lower end of the fixing bolt 11 is screwed into the corresponding threaded hole.

[0023] It should be noted that: First, place the two sections of oil pipeline to be connected on the V-shaped blocks 7 of the clamping and positioning mechanism on both sides, press down the arc plate 9 to make it fit the upper part of the pipeline, and then tighten the fixing bolts 11 on the fixing plates 10 on both sides. The lower end of the fixing bolts 11 is screwed into the threaded hole of the V-shaped block 7, thereby firmly clamping the pipeline between the V-shaped block 7 and the arc plate 9. The design of the V-shaped block 7 allows it to be naturally centered and initially support pipelines of different diameters.

[0024] It should be further explained that: the operator then manually pushes the convex slider 5, causing it to slide along the slide rod 3 towards the center of the device, initially aligning the pipe. When the pipe end reaches the docking position, the locking bolt 6 on the convex slider 5 is tightened. The lower end of the locking bolt 6 presses tightly against the anti-slip groove 4 on the upper surface of the U-shaped base 1, which has anti-slip texture. The resulting huge frictional force completely locks the convex slider 5. The reaction force generated during this locking process also acts as a continuous thrust, ultimately ensuring that the two pipe sections are tightly and accurately docked with the fixed butt joint located in the center of the device and the sealing ring is pressed, completing the sealed connection. The entire process requires no electricity and can be completed manually.

[0025] refer to Figure 1 As shown, the U-shaped base 1 has fixing holes 2 at all four corners, which facilitate the installation and fixing of the U-shaped base 1.

[0026] refer to Figure 1 As shown, two symmetrically arranged ribs 13 are fixedly connected to the bends on both sides of the U-shaped base 1. The ribs 13 make the structure of the U-shaped base 1 more stable.

[0027] refer to Figure 1 As shown, two symmetrically arranged guide rods 12 are fixedly connected to the upper surface of the V-shaped block 7. The guide rods 12 slide through the adjacent fixed plate 10. Through the guide rods 12, the clamping force of the arc plate 9 is ensured to be vertically downward, preventing the arc plate 9 from tilting. At the same time, it plays an auxiliary alignment role and facilitates operation.

[0028] The upper surface of the V-shaped block 7 and the lower surface of the arc plate 9 are both provided with anti-slip textures, which make the clamping of the pipe more stable.

[0029] refer to Figure 2 As shown, two wear-resistant copper sleeves 8 are slidably sleeved on the slide rod 3, and two convex sliders 5 are respectively fixedly sleeved on the two wear-resistant copper sleeves 8. The wear-resistant copper sleeves 8 reduce friction and make the sliding smoother.

[0030] The working principle of this utility model is as follows: First, the two sections of oil pipeline to be connected are placed on the V-shaped blocks 7 of the clamping and positioning mechanism on both sides. The arc plate 9 is pressed down to make it fit the upper part of the pipeline. Then, the fixing bolts 11 on the fixing plates 10 on both sides are tightened. The lower end of the fixing bolt 11 is screwed into the threaded hole of the V-shaped block 7, thereby firmly clamping the pipeline between the V-shaped block 7 and the arc plate 9. The design of the V-shaped block 7 allows it to naturally center and initially support pipelines of different diameters. Then, the operator manually pushes the convex slider 5 to slide it along the slide rod 3 towards the center of the device, initially driving the pipeline to center. When the pipeline end reaches the docking position, the locking bolt 6 on the convex slider 5 is tightened. The lower end of the locking bolt 6 presses tightly against the anti-slip groove 4 with anti-slip texture on the upper surface of the U-shaped base 1. The huge friction force generated completely locks the convex slider 5. The reaction force generated in this locking process also acts as a continuous pushing force. The force ensures that the two pipe sections are tightly and precisely connected to the fixed butt joint located at the center of the device, and the sealing ring is pressed to complete the sealed connection. The entire process requires no electricity and can be completed manually. In summary, this device completely eliminates complex electrical and transmission components such as motors and lead screws, and adopts a purely mechanical design of convex slider 5, locking bolt 6 and clamping mechanism. The structure is simple, the manufacturing cost is low, the failure rate is extremely low, and it completely avoids electrical safety hazards in flammable and explosive environments. It has extremely strong environmental adaptability. Moreover, the slider is locked and finally connected by manually tightening the locking bolt 6 to press against the anti-retraction groove 4. The locking force is huge and reliable, ensuring the stability of the connection and the durability of the seal. In addition, the combination clamping mechanism of V-block 7 and arc plate 9 can firmly clamp multiple diameter pipes within a certain size range by simply tightening and loosening the bolts, which greatly enhances the versatility and reduces the equipment investment cost.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
