[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0029] As Figures 1 to 5 shown, the present utility model provides a boiler pipeline support device, including a mounting plate 1 fixedly arranged at the bottom of the beam or the top plate through bolts. Both sides of the lower surface of the mounting plate 1 are fixedly provided with pillars 2, and the pillars 2 are symmetrically arranged on the lower surface of the mounting plate 1. Both sides of the lower surface of the mounting plate 1 are provided with bolt holes corresponding to the first bolts 10. The upper part of the pillar 2 is threadedly penetrated with the first bolts 10, and the pillar 2 is fixedly connected with the reserved holes of the mounting plate 1 through threaded connection of the first bolts 10. The structures of the two pillars 2 are the same, and the installation methods are also the same (as Figure 2 shown), and a lifting mechanism 4 is arranged in the inner cavities of both pillars 2.

[0030] The lifting mechanism 4 includes two second pulleys 46 rotatably arranged on both sides of the upper surface of the inner cavity of the support column 2, and the two second pulleys 46 are symmetrically arranged. The surfaces of the middle grooves of the two second pulleys 46 are both slidably arranged with the first steel wire rope 41. One end of the first steel wire rope 41 passes through the groove surface of the sun gear disc 43 and is fixedly connected to the second lifting ring 47, and the second lifting ring 47 is welded and fixed to the top of the inner cavity of the support column 2. On both sides of the outer surface of the middle part of the sun gear disc 43, they are both rotatably arranged with the connecting rods 48, and the two connecting rods 48 are symmetrically arranged. The middle part of the lower surface of the connecting rod 48 is fixedly connected to one end of two second steel wire ropes 42, and the other ends of the two second steel wire ropes 42 are both fixedly connected to two first lifting rings 45, and the two first lifting rings 45 are symmetrically welded side by side and fixed on one side of the upper surface of the reinforcing rib 12;

[0031] On the side of the two connecting rods 48 away from the sun gear disc 43, they are rotatably connected to the outer surface of the middle part of the first pulley 44. The surface of the middle groove of the first pulley 44 is slidably connected to the first steel wire rope 41. One end of the first steel wire rope 41 is fixedly connected to the second lifting ring 47, and the other end of the first steel wire rope 41 passes through the lower groove surface of the sun gear disc 43, then passes through the upper groove surface of the second pulley 46 fixedly arranged on the upper surface of the inner cavity of the support column 2 on the right side (as Figure 5 shown), and then passes through the lower groove surface of the first pulley 44, and then passes through the upper groove surface of the second pulley 46 fixedly arranged on the upper surface of the inner cavity of the support column 2 on the left side (as Figure 5 shown). Finally, one end of the first steel wire rope 41 is fixedly connected to the wire reel 36 in the locking mechanism 3. As described above, this connection method can form a movable pulley group, making it more labor-saving when longitudinally moving the pipeline.

[0032] The locking mechanism 3 includes a rotating shaft 32 fixedly arranged on one side of the outer surface of the lower part of the support column 2. The outer surface of one side of the rotating shaft 32 is rotatably connected to the inner surface of the rotating end of the ratchet pawl 34. The side of the ratchet pawl 34 away from the rotating shaft 32 is engaged with the ratchet wheel 31. The inner surface of the ratchet wheel 31 is fixedly connected to the outer surface of one side of the rotating rod 35, and the side of the rotating rod 35 away from the ratchet wheel 31 is fixedly connected to one side surface of the wire reel 36. On the outer side of the outer surface of the ratchet wheel 31, a handle 33 is fixedly arranged. When the handle 33 rotates the ratchet wheel 31, it drives the wire reel 36 to rotate, thereby realizing the tightening or releasing of the first steel wire rope 41. To sum up, this connection method can play a role in limiting and fixing when winding and unwinding the wire reel 36.

[0033] The outer surface of the lower end of the support column 2 is attached to the upper surface of one side of the reinforcing rib 12, and the surface of the side of the reinforcing rib 12 away from the support column 2 is fixedly connected to the outer surface of one side of the lower U-shaped clamp 14. The opening surface of the lower U-shaped clamp 14 is attached to the opening surface of the upper U-shaped clamp 6. Shock-absorbing foam 7 is adhesively provided on the inner cavity surfaces of both the lower U-shaped clamp 14 and the upper U-shaped clamp 6. The shock-absorbing foam 7 can be used to absorb the vibration of the pipeline during transportation and isolate the friction between the pipeline and the upper U-shaped clamp 6 and the lower U-shaped clamp 14. The outer surfaces on both sides of the opening of the upper U-shaped clamp 6 are fixedly connected to the surface of one side of the fixing block 5, and a second bolt 11 is threadedly penetrated through the middle of the fixing block 5. A threaded groove 13 is provided on the upper surface of the side where the reinforcing rib 12 is fixedly connected to the lower U-shaped clamp 14. The position of the threaded groove 13 corresponds to that of the second bolt 11 and they are threadedly connected to each other (as Figure 4 shown). To sum up, this connection method can fix the pipeline and prevent frictional loss between the pipeline and the upper U-shaped clamp 6 and the lower U-shaped clamp 14.

[0034] Two fixing columns 9 are fixedly provided on the outer surfaces on both sides of the lower part of the support column 2, and two opening hooks 8 are fixedly provided on the outer surfaces on both sides of one end of the reinforcing rib 12 away from the lower U-shaped clamp 14. The two opening hooks 8 correspond to the two fixing columns 9 and are engaged with each other (as Figure 1 shown). The engagement of the opening hook 8 and the fixing column 9 can fix the reinforcing rib 12 at the lower end of the support column 2 to prevent the pipeline from falling downward due to gravity and vibration.

[0035] The principle and process of the present utility model:

[0036] Generally, when installing the pipeline, the staff will first determine the pipeline layout route according to the drawing, measure the distance according to the specification, and then fix the mounting plate 1 in the present device to the top plate or the bottom of the beam by bolts. After fixing, the staff first separates the opening hook 8 from the fixing column 9, then separates the pawl 34 from the ratchet wheel 31, and at the same time rotates the handle 33 to drive the ratchet wheel 31 to rotate. The rotation of the ratchet wheel 31 drives the rotating rod 35 to rotate, and further drives the wire reel 36 to rotate to release the first steel wire rope 41. The first steel wire rope 41 can easily move the reinforcing rib 12 attached to the bottom of the support column 2 downward through the labor-saving pulley group composed of the first pulley 44, the second pulley 46, and the sun gear disc 43.

[0037] When the reinforcing rib 12 moves to a position convenient for installing the pipeline, the staff can engage the pawl 34 with the ratchet wheel 31, then use a wrench to remove the second bolt 11 that is threadedly penetrated through the fixing block 5 and threadedly fixed in the threaded groove 13, remove the upper U-shaped clamp 6, then place the pipeline inside the lower U-shaped clamp 14, then align and attach the upper U-shaped clamp 6 and the lower U-shaped clamp 14 so that the shock-absorbing foam 7 completely wraps the pipeline, and then tighten the second bolt 11 with a wrench;

[0038] Subsequently, the staff releases the pawl 34 and rotates the handle 33 in the reverse direction, driving the ratchet wheel 31 and the wire reel 36 to rotate in the reverse direction, thereby tightening the first steel wire rope 41. After the upper surface of the reinforcing rib 12 is completely fitted with the lower surface of the pillar 2, the ratchet wheel 31 and the pawl 34 are engaged with each other and limited, and then the opening hook 8 is engaged and fixed with the fixed column 9, and the entire installation process is completed. The same steps are also applicable for replacing the pipeline.
