Detailed Implementation

[0029] The following non-limiting examples are used to illustrate the present invention.

[0030] Example 1:

[0031] refer to Figure 1 and Figure 2 As shown, a pressure pipeline installation docking auxiliary device includes a base 1, a mounting plate 2, a mounting platform 3, a first fixing frame 4, a fixing platform 7, a second fixing frame 8, and a support base 9.

[0032] The base 1 supports the mounting plate 2 via a shock-absorbing assembly, which in turn reduces vibrations transmitted from the mounting plate 2 to the base 1. A fixed platform 7 is fixedly mounted on the left side of the mounting plate 2. A second fixed frame 8, which rotates axially (horizontally and longitudinally) along the pipeline, is mounted on the fixed platform 7. The second fixed frame 8 secures the left-side raw material pipeline, and its rotation allows for adjustment and alignment of the connecting holes on the left-side raw material pipeline. A mounting platform 3, movable away from or near the fixed platform 7, is mounted on the right side of the mounting plate 2. A first fixed frame 4 is mounted on the mounting platform 3, securing the right-side raw material pipeline. The movement of the first fixed frame 4, driven by the mounting platform 3, allows the right-side raw material pipeline to approach and connect with the left-side raw material pipeline. Both the first fixed frame 4 and the second fixed frame 8 are equipped with inwardly and outwardly movable pipe clamping components. The pipe clamping components move inward to clamp the pipeline onto the fixed frames, and move outward to release the pipeline.

[0033] The top of the mounting plate 2 is provided with a movable groove 5 arranged in a horizontal longitudinal direction. The mounting platform 3 is slidably disposed in the movable groove 5. The mounting plate 2 or the fixed platform 7 is connected to the mounting platform 3 through a sliding drive component. The sliding drive component is an electric telescopic rod 6. The electric telescopic rod 6 provides power to pull the mounting platform 3 and the first fixed frame 4 together toward or push away from the second fixed frame 8.

[0034] refer to Figure 3 As shown, both the first fixing frame 4 and the second fixing frame 8 are circular rings with the axis of horizontal longitudinal direction. Both the first fixing frame 4 and the second fixing frame 8 are provided with several pipe clamping components arranged in the circumferential direction. The circumferentially arranged pipe clamping components are used to achieve stable clamping of the circular pipe.

[0035] Two support plates 11 are fixed on the fixed platform 7, located on the front and rear sides respectively. A mounting ring 12 is fixed between the two support plates 11. The axis of the mounting ring 12 is horizontal and vertical. The second fixed frame 8 is rotatably sleeved inside the mounting ring 12, which supports the second fixed frame 8 and allows it to rotate. The fixed platform 7 is equipped with a rotation drive assembly connected to the second fixed frame 8, which controls the rotation of the second fixed frame 8 on the fixed platform 7.

[0036] The rotary drive assembly includes a gear ring 13, a mounting port 14, a drive gear 15, and a drive motor 16. The drive motor 16 is fixed on the fixed platform 7, and the mounting port 14 is opened on the fixed platform 7. The rotating drive gear 15 is located inside the mounting port 14. The drive motor 16 is connected to the drive gear 15. The gear ring 13 is fixed on the outer circumference of the second fixed frame 8. The drive gear 15 meshes with the gear ring 13. The drive motor 16 drives the drive gear 15 to rotate, and the drive gear 15 then drives the gear ring 13 to rotate. The second fixed frame 8 and the gear ring 13 rotate synchronously, thereby adjusting the position of the connection hole on the left raw material pipeline.

[0037] Start the drive motor 16, which drives the drive gear 15 to rotate. Since the drive gear 15 meshes with the gear ring 13 on the second fixed frame 8, it drives the second fixed frame 8 to rotate, thereby rotating the pressure pipeline. When there are flanges on the surface of the pressure pipeline, the drive motor 16 can drive one of the pressure pipelines to rotate, ensuring precise alignment of the bolt holes on the flanges of the two pressure pipelines. This facilitates docking by operators without the need for manual adjustment before docking, thus improving the flexibility of the device during use.

[0038] refer to Figure 4 As shown, the pipe clamping assembly includes a fixing component 17, a mounting component 18, an electric push rod 19, a connecting plate 20, an elastic pressure rod 21, a fixing rod 22, a fixing plate 23, a rubber flexible plate 24, a mounting bracket 25, an adjusting spring rod 26, and an adjusting rod 27. The fixing component 17 and the mounting component 18 are both fixed to the inner circumference of either the first fixing frame 4 or the second fixing frame 8. The fixing component 17 is hinged to the outer end of the adjusting rod 27, the mounting component 18 is hinged to the inner end of the electric push rod 19, and the inner end of the adjusting rod 27 is hinged to the outer end of the electric push rod 19. The upper end of the adjusting rod 27 is provided with a connecting plate 20 that rotates tangentially along the outer wall of the pipe. The outer side of the connecting plate 20 is provided with a mounting bracket 25, and an adjusting spring rod 26 is hinged between the mounting bracket 25 and the upper end face of the adjusting rod 27. The connecting plate 20 is provided with a fixing rod 22, and the fixing rod 22 is provided with a fixing plate 23. Rubber flexible plates 24 extend from both outer sides of the fixing plate 23. An elastic pressure rod 21 is provided between the rubber flexible plate 24 and the connecting plate 20. The upper surfaces of the fixing plate 23 and the rubber flexible plate 24 are textured to improve the contact effect.

[0039] During fixing, the two pressure pipes that need to be connected are placed inside the first fixing frame 4 and the second fixing frame 8, respectively. After placement, the electric push rod 19 is extended and retracted, causing the electric push rod 19 to drive the adjusting rod 27 to rotate. In turn, the adjusting rod 27 drives the connecting plate 20 to rotate, and the connecting plate 20 drives the fixing plate 23 to move, so that the fixing plate 23 contacts the surface of the pressure pipe, thereby fixing the raw material pipe. At the same time, when the fixing plate 23 fixes the pressure pipe, the elastic pressure rod 21 causes the rubber flexible plate 24 to deform, so that the rubber flexible plate 24 fits against the surface of the pressure pipe.

[0040] By setting up multi-directional fixing plates 23, the contact area between the fixing plates 23 and the pipe surface is increased during fixing, improving the stability of the fixing process. Furthermore, during fixing, the elastic pressure rod 21 drives the rubber flexible plate 24 to fit against the pressure pipe surface, thus avoiding gaps between the fixing device and the pipe surface, improving the fixing effect and increasing the accuracy of the connection. Simultaneously, the angle of the adjusting rod 27 can be adjusted by the electric push rod 19 during fixing, allowing the device to be used with pressure pipes of different sizes, thereby increasing its practicality. Adjusting the spring rod 26 ensures that the surface of the fixing plate 23 always faces the pressure pipe surface when the electric push rod 19 adjusts the angle of the adjusting rod 27, guaranteeing the fixing effect.

[0041] refer to Figure 5 As shown, the mounting plate 2 is provided with four support seats 9, and two are arranged on the outer side of the mounting platform 3 and the fixing platform 7. The support seats 9 are provided with internal and external adjustable pipe support components. The pipes are supported by two opposing pipe support components.

[0042] The pipe support assembly includes a support member 28, a connector 29, an adjusting screw 30, and a limiting rod 31. The upper end face of the support member 28 is an arc-shaped end face that contacts the pipe. The support member 28 is rotatably connected to the adjusting screw 30, which is threadedly engaged with the connector 29. The connector 29 is fixed to the support base 9. Rotating the adjusting screw 30 adjusts the distance between the support member 28 and the support base 9. The support member 28 is fixedly connected to the limiting rod 31, which slides through a limiting hole in the support base 9. The limiting rod 31 limits and guides the support member 28, and together with the adjusting screw 30, maintains the posture of the support member 28.

[0043] While fixing the pipe, rotating the adjusting screw 30 moves the support member 28, causing it to contact the surface of the pressure pipe and support it. This support reduces warping caused by the pipe's length and weight, further improving the accuracy of the connection. The adjusting screw 30 allows for adjustment of the support member 28's position according to the size of the pressure pipe, enhancing the device's effectiveness. Simultaneously, the limiting rod 31 limits the support member 28's position, eliminating the need for manual support during pipe fixing and reducing worker workload.

[0044] refer to Figure 6 As shown, the mounting platform 3 is equipped with a platform buffer assembly opposite to the fixed platform 7. When the distance between the mounting platform 3 and the fixed platform 7 is too close, the platform buffer assembly is used to buffer the transition and avoid rigid collision between the two.

[0045] The platform cushioning assembly includes a mounting rod 32, a cushioning spring rod 33, a cushioning element 34, a fixing port 35, a rubber pad 36, and a cushioning rod 37. The fixing port 35 is located on the mounting platform 3. The lower end of the cushioning rod 37 is hinged to the fixing port 35 via the mounting rod 32. The upper outer side of the cushioning rod 37 is provided with a rubber pad 36. The cushioning element 34 is located inside the fixing port 35. The cushioning spring rod 33 is hinged between the upper inner side of the cushioning rod 37 and the cushioning element 34.

[0046] During docking, the electric telescopic rod 6 extends and retracts, causing the mounting platform 3 to move within the movable slot 5, thereby bringing the two pressure pipes closer together. This allows the operator to dock the pressure pipes. If the electric telescopic rod 6 extends too far during this close-up maneuver, the buffer rod 37 and buffer spring rod 33 cushion the impact on the fixed platform 7 and mounting platform 3. The buffer rod 37 and buffer spring rod 33 absorb energy during this process, ensuring the device can effectively cushion the impact on the fixed platform 7 and mounting platform 3. The buffer rubber pad 36 prevents damage to the fixed platform 7 and mounting platform 3 and avoids collisions between the pressure pipes during use, thus improving the safety of the device during operation.

[0047] refer to Figure 7 As shown, the shock absorption assembly includes a connecting spring rod 10, a shock absorption spring 38, a movable member 39, a support rod 40, a shock absorber 41, and a guide slide rod 42. A vertical connecting spring rod 10 is provided between the base 1 and the mounting plate 2. A horizontal guide slide rod 42 is provided on the base 1, and a movable member 39 is slidably mounted on the guide slide rod 42. A shock absorption spring 38 is provided between the base 1 and the movable member 39. The movable member 39 is hinged to the support rod 40, the support rod 40 is hinged to the shock absorber 41, and the shock absorber 41 is connected to the mounting plate 2.

[0048] When the device is subjected to impact and vibration, the connecting spring rod 10 reduces the vibration. Simultaneously, the vibration is transmitted to the support rod 40 via the damping element 41. This causes the support rod 40 to move the movable element 39 along the guide slide rod 42, compressing the damping spring 38. The friction between the movable element 39 and the guide slide rod 42 further reduces the vibration. The connecting spring rod 10 provides initial cushioning, and the support rod 40 and damping spring 38 further enhance the device's damping effect, enabling rapid vibration elimination. This increases the device's stability during use, reduces noise during impacts, and enhances its functionality.

[0049] The working process of this invention:

[0050] In use, the two pressure pipes that need to be connected are placed inside the first fixing frame 4 and the second fixing frame 8, respectively. After placement, the electric push rod 19 is extended and retracted, causing the electric push rod 19 to drive the adjusting rod 27 to rotate. In turn, the adjusting rod 27 drives the connecting plate 20 to rotate, and the connecting plate 20 drives the fixing plate 23 to move, so that the fixing plate 23 comes into contact with the surface of the pressure pipe, thereby fixing the raw material pipe. At the same time, when the fixing plate 23 fixes the pressure pipe, the elastic pressure rod 21 can drive the rubber soft plate 24 to deform, so that the rubber soft plate 24 fits against the surface of the pressure pipe.

[0051] Furthermore, while the device is fixed, the adjusting screw 30 is rotated to move the support member 28, thereby bringing the support member 28 into contact with the surface of the pressure pipeline and supporting the pressure pipeline.

[0052] During docking, the electric telescopic rod 6 extends and retracts, causing the mounting platform 3 to move inside the movable groove 5, thereby bringing the two pressure pipes closer together, allowing the workers to dock the pressure pipes. When the electric telescopic rod 6 extends too much when they get close, the buffer rod 37 and the buffer spring rod 33 can buffer the fixed platform 7 and the mounting platform 3.

[0053] When a flange is present on the surface of the pressure pipeline, the drive motor 16 is started, which drives the drive gear 15 to rotate. Since the drive gear 15 meshes with the gear ring 13 on the second fixed frame 8, the drive gear 15 can drive the second fixed frame 8 to rotate, thereby driving the pressure pipeline to rotate.

[0054] When the device is impacted and vibrates, the vibration can be reduced by connecting spring rod 10. At the same time, the vibration is transmitted to the support rod 40 through the shock absorber 41, which in turn causes the support rod 40 to drive the movable part 39 to move on the guide slide rod 42, and the movable part 39 to compress the shock absorber spring 38. Due to the friction between the movable part 39 and the guide slide rod 42, the vibration of the device is reduced.

[0055] The foregoing basic examples and their further alternative examples of the present invention can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed by the present invention. In the present invention, each alternative example can be arbitrarily combined with any other basic example and alternative example.
