[0028] In the present embodiment, it also includes a second telescopic column 16, a support plate 17 on the top outer surface of the second telescopic column 16, a threaded rod 18 is rotatably connected to the top outer surface of the support plate 17, a threaded tube 19 is threadedly connected to the outer surface of the threaded rod 18, a side plate is fixedly connected to the top outer surface of the support plate 17, a rotating shaft 20 is rotatably penetrated through the outer surface of the side plate, a driving bevel gear 21 is fixedly sleeved on one side of the rotating shaft 20, a driven bevel gear 22 is fixedly sleeved on the outer surface of the threaded rod 18, and a crank is fixedly connected to the side of the rotating shaft 20 away from the driving bevel gear 21.

[0032] Embodiment 2:

[0033] Please refer to Figure 1-Figure 7 The present invention provides a technical solution: in this embodiment, the bottom outer surface of the intermediate support shaft 7 is fixedly connected with a fixing plate 9, the bottom outer surface of the fixing plate 9 is fixedly connected with a connecting column 10, the bottom outer surface of the connecting column 10 is fixedly connected with an adjusting plate 11, the bottom outer surface of the adjusting plate 11 is fixedly connected with a first spring 12, the bottom outer surface of the first spring 12 is fixedly connected with a connecting plate, the bottom outer surface of the adjusting plate 11 and the top outer surface of the connecting plate are both rotatably connected with a plurality of adjusting plates 13 in a circular array, a connecting plate 14 is rotatably connected between the upper and lower adjusting plates 13, and the bottom outer surface of the adjusting plate 11 Several fixed plates are fixedly connected, and a second spring 15 is fixedly connected between the several fixed plates and the connecting plate 14. Specifically, when oil flows in the oil pipeline, the connecting column 10 is subjected to force to make the adjusting disk 11 move downward, so that the first spring 12 is deformed, and the two adjusting plates 13 change their angles between the connecting plates 14, and drive the connecting plates 14 to deform the second spring 15, and the friction between the connecting plate 14 and the adjusting plate 13 eliminates the force of the first spring 12 and the second spring 15, so that the unstable force generated when the oil flows is buffered by the first spring 12 and the second spring 15.

[0034] In this embodiment, the bottom outer surfaces of the support shafts 7 on both sides are rotatably connected to the third telescopic columns 24, and the other ends of the two third telescopic columns 24 are rotatably connected to the rotating cylinders 23. The two rotating cylinders 23 are arranged up and down and rotatably sleeved on the outer surface of the connecting column 10. Specifically, the force of the oil flow is transmitted to the lower arc-shaped clamping plate 2, and the lower arc-shaped clamping plates 2 on both sides transmit the force to the rotating cylinders 23 through the third telescopic columns 24, and finally transmit it to the connecting column 10. By adjusting the length of the third telescopic columns 24, the distance between multiple lower arc-shaped clamping plates 2 can be adjusted, thereby adjusting the supporting position of the lower arc-shaped clamping plates 2 on the oil pipeline.

[0035] In the present embodiment, the first telescopic column 8, the second telescopic column 16 and the third telescopic column 24 all include a fixed rod and a movable rod. The outer surfaces of the fixed rod and the movable rod are provided with screw holes. There are several screw holes on the surface of the movable rod and they are arranged in a linear array. The screw holes corresponding to the fixed rod and the movable rod are threadedly connected with an adjusting hand wheel. Specifically, by unscrewing the adjusting hand wheel, adjusting the position of the movable rod in the fixed rod, and then screwing the adjusting hand wheel into the corresponding screw hole, the fixed rod and the movable rod are limited, and the overall length of the telescopic column is adjusted.

[0036] In this embodiment, a fixing nail is fixedly connected to the bottom outer surface of the second telescopic column 16, and a plurality of reinforcing rods 25 are arranged in a circular array on the outer surface of the second telescopic column 16. The bottom outer surfaces of the plurality of reinforcing rods 25 are rotatably connected to fixing feet 26, and the bottom outer surfaces of the fixing feet 26 are fixedly connected to inserting nails 27. Specifically, when fixing the supporting device, the fixing nails at the bottom of the second telescopic column 16 are inserted into the ground, and the reinforcing rods 25 are rotated on the surface of the second telescopic column 16, and the inserting nails 27 are inserted into the ground. The second telescopic column 16 is supported around by the reinforcing rods 25, thereby increasing the stability of the device.

[0037] In the specific implementation process, when the oil pipeline is transporting oil, the flow of oil in the oil pipeline may cause an offset effect on the device. At this time, the force of the oil flow is transmitted to the lower arc clamping plate 2, and the lower arc clamping plates 2 on both sides transmit the force to the rotating drum 23 through the third telescopic column 24, and finally transmit it to the connecting column 10. The connecting column 10 is subjected to force to make the adjustment disk 11 move downward, so that the first spring 12 is deformed, and the two adjustment plates 13 change their angles between the connecting plates 14, and drive the connecting plates 14 to deform the second spring 15. The friction between the connecting plate 14 and the adjustment plate 13 eliminates the force of the first spring 12 and the second spring 15, so that the unstable force generated by the flow of oil is buffered by the first spring 12 and the second spring 15, and when fixing the support device, the fixing nail at the bottom of the second telescopic column 16 is inserted into the ground, and the reinforcing rod 25 is rotated on the surface of the second telescopic column 16, and the nail 27 is inserted into the ground, and the surrounding of the second telescopic column 16 is supported by the reinforcing rod 25, thereby increasing the stability of the device.

[0038] Working principle: When the present invention is in use, when it is necessary to support the bent pipe, the positions between the multiple groups of lower arc-shaped clamps 2 are adjusted. At this time, force is applied to the lower arc-shaped clamps 2, so that the multiple groups of rotating blocks 5 rotate on the damping rotating rod 4, so that the middle lower arc-shaped clamp 2 is located at the bent pipe, and the other two groups of lower arc-shaped clamps 2 are located at the two connected straight pipes. By adjusting the degree of rotation between each connecting block 3 and the rotating block 5, the distance between the three lower arc-shaped clamps 2 can be adjusted. When the three lower arc-shaped clamps 2 are adjusted, the first telescopic column 8 rotates on the support shaft 7, and when adjusting the distance between the three lower arc-shaped clamps 2, the length of the first telescopic column 8 is adjusted, and then by Adjust the height of the second telescopic column 16, roughly adjust the height of the lower arc splint 2, and then turn the crank to drive the shaft 20 to rotate, the shaft 20 drives the active bevel gear 21 to rotate, and drives the driven bevel gear 22 to rotate the threaded rod 18, and the threaded rod 18 drives the threaded cylinder 19 to move, and fine-tune the height of the arc splint, so that the lower arc splint 2 moves upward, so that the lower arc splint 2 fits with the bottom of the oil pipeline, and then align the connecting hole on the upper arc splint 1 with the connecting hole on the lower arc splint 2, screw the connecting bolt 6 into the corresponding connecting hole, and then screw the nut into the connecting bolt 6 to connect the upper arc splint 1 and the lower arc splint 2.

[0039] When the oil pipeline is transporting oil, the flow of oil in the oil pipeline may cause an offset effect on the device. At this time, the force of the oil flow is transmitted to the lower arc clamping plate 2, and the lower arc clamping plates 2 on both sides transmit the force to the rotating drum 23 through the third telescopic column 24, and finally transmit it to the connecting column 10. The connecting column 10 is subjected to force to make the adjusting disk 11 move downward, so that the first spring 12 is deformed, and the two adjusting plates 13 change their angles between the connecting plates 14, and drive the connecting plates 14 to deform the second spring 15. The friction between the connecting plates 14 and the adjusting plates 13 eliminates the force of the first spring 12 and the second spring 15, so that the unstable force generated by the flow of oil is buffered by the first spring 12 and the second spring 15, and when fixing the supporting device, the fixing nail at the bottom of the second telescopic column 16 is inserted into the ground, and the reinforcing rod 25 is rotated on the surface of the second telescopic column 16, and the nail 27 is inserted into the ground, and the surrounding of the second telescopic column 16 is supported by the reinforcing rod 25, thereby increasing the stability of the device.
