[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a pipeline erection support device for chemical engineering construction.

[0034] Example 1

[0035] Reference Figure 1 and Figure 2 A chemical engineering construction pipeline erection support device comprises a support mechanism 1, a limiting mechanism 2 and a lifting mechanism 3. The support mechanism 1 is used to connect with the ground, the limiting mechanism 2 is used for pipeline installation, the two ends of the lifting mechanism 3 are respectively connected to the support mechanism 1 and the limiting mechanism 2, and the lifting mechanism 3 is used to drive the limiting mechanism 2 to rise and fall.

[0036] Specifically, the support mechanism 1 includes a base plate 11 and fixing bolts 12 . A plurality of fixing bolts 12 are provided. The plurality of fixing bolts 12 are arranged at intervals around the central axis of the base plate 11 . The fixing bolts 12 are used to fix the base plate 11 to the ground.

[0038] A connecting rope 15 is fixedly connected to the top of the fixing bolt 12 , and one end of the connecting rope 15 away from the fixing bolt 12 is fixedly connected to the top of the positioning pin 14 to reduce the risk of losing the positioning pin 14 .

[0039] The lifting mechanism 3 includes a hollow column 31, a lifting column 32 and a cylinder 33. The hollow column 31 is fixed to the center of the bottom plate 11. One end of the hollow column 31 close to the bottom plate 11 is closed, and the other end has a sliding opening. The lifting column 32 is located in the hollow cavity of the hollow column 31, and the outer wall of the lifting column 32 abuts against the inner wall of the sliding opening, so that the lifting column 32 is slidably connected to the hollow column 31 along the length direction of the hollow column 31. The cylinder 33 is fixed to the bottom wall of the hollow column 31, and the output end of the cylinder 33 is connected to the lifting column 32, so that the lifting column 32 is driven by the cylinder 33 to move along the height direction of the hollow column 31.

[0040] To improve the connection stability between the hollow column 31 and the bottom plate 11, a plurality of reinforcing plates 16 are fixedly connected to the circumference of the hollow column 31. The plurality of reinforcing plates 16 are arranged at intervals along the circumference of the hollow column 31. The reinforcing plates 16 are arranged in a triangular shape, and the other side of the reinforcing plates 16 is fixedly connected to the bottom plate 11.

[0041] The limiting mechanism 2 includes a fixed frame 21, a movable frame 22 and a positioning assembly 23. The fixed frame 21 is connected to one end of the lifting column 32 away from the bottom plate 11, and the fixed frame 21 is used to set up the pipeline. A back plate 211 is fixedly connected to one side of the fixed frame 21, and the movable frame 22 is slidably connected to the back plate 211 along the height direction of the lifting column 32, and the movable frame 22 is used for the upper part of the pipeline to abut. The positioning assembly 23 is used to fix the movable frame 22 to the back plate 211 after the movable frame 22 slides relative to the back plate 211, so as to clamp the pipeline with the fixed frame 21 and the movable frame 22, thereby limiting the pipeline.

[0042] Reference Figure 2 and Figure 3 In this embodiment, the positioning assembly 23 includes a first support plate 231, a second support plate 232, a threaded rod 233, a servo motor 234 and a connecting plate 235. The first support plate 231 and the second support plate 232 are both connected to the surface of the back plate 211 away from the movable frame 22, and the second support plate 232 is located above the first support plate 231. The two ends of the screw rod are rotatably connected to the first support plate 231 and the second support plate 232 respectively through bearings, and the servo motor 234 is connected to the upper surface of the second support plate 232, and the servo motor 234 is used to drive the threaded rod 233 to rotate. The connecting plate 235 is provided with a threaded hole for threaded engagement with the threaded rod 233, and the back plate 211 is provided with a through slot 222, and the connecting plate 235 is fixedly connected to the upper surface of the movable frame 22 through the through slot 222.

[0043] When laying the pipeline, first lay the pipeline on the fixed frame 21, then start the servo motor 234, and use the servo motor to drive the threaded rod 233 to rotate, so that the connecting plate 235 threadedly connected to the threaded rod 233 moves downward, and then drives the movable frame 22 to move downward. Finally, the movable frame 22 abuts against the pipeline to achieve the clamping of the fixed frame 21 and the movable frame 22 on the pipeline. The structure is simple and easy to operate.

[0044] The implementation principle of Example 1 is as follows: when erecting a pipeline, first start the cylinder 33, and use the cylinder 33 to drive the lifting column 32 to move upward or downward, and move the limiting mechanism 2 to a suitable height; then erect the pipeline on the fixed frame 21; then start the servo motor 234, and the servo motor 234 drives the threaded rod 233 to rotate, and then drives the movable frame 22 to move downward through the connecting plate 235, so that the movable frame 22 abuts against the pipeline, completing the clamping and limiting of the pipeline, which is simple to operate and effectively improves the efficiency of pipeline erection.

[0045] Example 2

[0046] Reference Figure 4 The difference between this embodiment and embodiment 1 is that the limiting mechanism 2 also includes an air cylinder 24, a first air bag 25 and a second air bag 26, the air cylinder 24 is connected to the first support plate 231, and the end of the connecting plate 235 away from the back plate 211 is connected to the piston rod of the air cylinder 24.

[0047] The first airbag 25 is connected to the surface of the movable frame 22 facing the fixed frame 21, and the inner cavity of the first airbag 25 is connected to the air outlet of the air cylinder 24. The second airbag 26 is connected to the surface of the fixed frame 21 facing the movable frame 22, and the inner cavity of the second airbag 26 is connected to the air outlet of the air cylinder 24.

[0048] When the servo motor 234 drives the threaded rod 233 to rotate and then drives the connecting plate 235 to move downward, the connecting plate 235 drives the piston rod to move downward, pressing the gas in the gas cylinder 24 into the first airbag 25 and the second airbag 26. Finally, the first airbag 25 and the second airbag 26 filled with gas are respectively in contact with the upper and lower surfaces of the pipeline, so that there are deformable flexible contact points between the pipeline and the movable frame 22; thereby, in a vibrating environment, on the one hand, the risk of damage to the pipeline by collision with the limiting mechanism 2 is reduced, and on the other hand, a shock-absorbing effect is played to reduce the risk of pipeline rupture.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
