Both the front and rear ends of the lower side of the arc-shaped backing plate 1 are fixedly connected with baffles 9. The lower ends of the arc-shaped clamping plates 3 are in close fit with the inner wall of the arc-shaped backing plate 1. An opening 8 is provided in the middle of the upper end of the arc-shaped backing plate 1. The arc-shaped clamping plates 3 are respectively movably connected inside the opening 8. Grooves 4 are provided on the opposite sides of the arc-shaped clamping plates 3. Bolt holes 5 are provided in the upper end of the arc-shaped backing plate 1. Pin bolts 6 are inserted into the bolt holes 5. The outer wall of the pin bolt 6 is in close fit with the inner wall of the groove 4. Limit rods 7 are inserted into the ends of the pin bolts 6.

[0025] The provided arc-shaped clamping plate 3 can rotate through the rotating shaft 2 to open the top of the arc-shaped clamping plate 3. The provided arc-shaped clamping plate 3 rotates through the rotating shaft 2 and can be closely attached to form a circle and closely adhere to the surface of the pipeline. The pipeline is placed from the upper side of the arc-shaped backing plate 1. The descending pipeline contacts the lower end of the arc-shaped clamping plate 3 and drives the arc-shaped clamping plate 3 to rotate and closely adhere to the outer wall of the pipeline, thereby fixing the pipeline. Compared with the traditional bolt fixation, the operation is more convenient, improving the efficiency of pipeline installation. Passing the pin bolt 6 through the bolt hole 5 can limit and fix the arc-shaped clamping plate 3 and improve the strength of pipeline fixation.

[0026] Refer to Figure 1 、 Figure 3 and Figure 4 As shown in, a fixing ear 10 is fixedly connected to the top of the arc-shaped clamping plate 3. A semi-threaded hole 11 is arranged inside the fixing ear 10. A connecting plate 12 is arranged on the upper side of the fixing ear 10. Sliding blocks 13 are slidably connected to the left and right ends of the lower side of the connecting plate 12. An adjusting groove 14 is formed on the upper side of the connecting plate 12. An inner hexagon bolt 15 is movably connected to the inside of the adjusting groove 14. The lower ends of the inner hexagon bolts 15 respectively penetrate through the middle parts of the sliding blocks 13 and are fixedly connected to the inside of the semi-threaded hole 11. A protective cover plate 16 is arranged on the upper side of the connecting plate 12. Fasteners 17 are respectively arranged through the left and right ends of the protective cover plate 16. The lower ends of the fasteners 17 are threadedly connected to the left and right ends of the connecting plate 12.

[0027] When installing the pipeline, the position is adjusted by sliding the provided sliding blocks 13 in the connecting plate 12 and then sleeving them outside the fixing ears 10. When the two fixing ears 10 are attached together, the semi-threaded holes 11 on both sides form a complete threaded hole. The lower ends of the inner hexagon bolts 15 penetrate through the sliding blocks 13 and are threadedly connected to the semi-threaded holes 11 to fix the connecting plate 12 on the top of the fixing ears 10. The provided fasteners 17 are connected to the adjusting groove 14, and the protective cover plate 16 can be fixed on the upper side of the connecting plate 12. The provided protective cover plate 16 can protect the pipeline, reducing the possibility of the pipeline being impacted, thereby avoiding pipeline damage and increasing the service life of the pipeline.

[0028] Refer to Figure 1 and Figure 5 As shown in, support columns 18 are arranged below the arc-shaped backing plate 1. Lifting rods 19 are respectively arranged through the front and rear sides of the upper ends of the support columns 18. The top parts of the lifting rods 19 are respectively fixedly connected to the lower side of the arc-shaped backing plate 1. The bottom of the support column 18 is fixedly connected to a first bottom plate 20. Second bottom plates 21 are fixedly connected to the front and rear ends of the lower side of the first bottom plate 20. A rotating disk 22 is rotatably connected to the middle part of the upper side of the support column 18. A threaded rod 23 is threadedly connected to the middle part of the rotating disk 22.

[0029] The provided rotating disk 22 can rotate on the top of the support column 18. The threaded rod 23 is fixed to the lower side of the arc-shaped backing plate 1. The provided arc-shaped backing plate 1 is restricted by the lifting rod 19 and cannot rotate, so that the threaded rod 23 cannot rotate. When the rotating disk 22 rotates, it can drive the rotating disk 22 to move up and down, thereby driving the arc-shaped backing plate 1 to lift and adjust the height, so as to adjust according to requirements, which is convenient for fixing the pipeline at different heights.

[0030] Working principle: The support column 18 is fixed to the ground through the provided first bottom plate 20 and second bottom plate 21. Rotate the provided U-shaped rod 24, and drive the arc-shaped backing plate 1 to rise through the cooperation of the U-shaped rod 24 and the threaded rod 23 to adjust the height. Place the chemical pipeline from the upper side of the arc-shaped backing plate 1 and between the two arc-shaped clamping plates 3 on both sides. The falling pipeline contacts the upturned end at the lower end of the arc-shaped clamping plate 3. Apply a force through the pipeline and act on the lower end of the arc-shaped clamping plate 3, driving the arc-shaped clamping plate 3 to rotate on the arc-shaped backing plate 1 through the rotating shaft 2, so that the two arc-shaped clamping plates 3 form a circle and closely adhere to the outer wall of the pipeline. Then pass the bolt 6 through the bolt hole 5, and then insert the limiting rod 7 into the through hole provided at the end of the bolt 6. Cover the sliding block 13 on the top of the fixed ear 10, and pass the hexagon socket head bolt 15 through the sliding block 13 and thread it into the semi-threaded hole 11 to fix the connecting plate 12 on the top of the fixed ear 10.
