Description

Technical Field

[0001] This utility model relates to the field of chemical pipeline technology, and in particular to a chemical pipeline anti-fracture protection mechanism for chemical equipment. Background Technology

[0002] A search revealed that application number 202222775249.2 discloses a chemical pipeline anti-fracture protection mechanism, including a pipeline body. A first upper fixing component is sleeved on the left side of the outer surface of the pipeline body. A first lower fixing component is movably installed on the rear side of the outer surface of the first upper fixing component via a hinge. A second upper fixing component is sleeved on the right side of the outer surface of the pipeline body. A second lower fixing component is movably installed on the rear side of the outer surface of the second upper fixing component via a hinge. Two mounting components are interlocked at the upper ends of both the first and second upper fixing components.

[0003] The chemical pipeline anti-fracture protection mechanism in this patent application uses an upper fixing ring and a lower fixing ring to form a protective effect at the welded joint of the pipeline body. The upper and lower fixing rings are then fixed by a screw and a sleeve threaded connection. However, in this way, only one end of the upper and lower fixing rings is fixed, while the other end is in a movable state, which affects the fixing effect on the pipeline body and reduces the practicality of the device. Therefore, we propose a chemical pipeline anti-fracture protection mechanism for chemical equipment. Utility Model Content

Mounting brackets are symmetrically fixedly installed at both ends of the bottom of the upper fixing ring. Movable grooves are symmetrically opened in the middle of the two mounting brackets. Two movable blocks, fixedly installed at the top ends of the lower fixing ring, are movably disposed inside the two movable grooves. Two positioning slots are opened through the middle of the front wall of the two movable blocks. Two positioning slots and two movable grooves are respectively opened on the front and rear side walls of the two movable grooves, corresponding to the positions of the two positioning slots. A positioning mechanism is provided inside each of the two positioning slots. The positioning mechanism includes a first positioning rod and a second positioning rod, which are slidably connected to the front and rear ends of the positioning slots, respectively. The ends of the first and second positioning rods that are far apart from each other are inserted into the positioning slots and movable grooves, respectively. A hexagonal sliding post is fixedly connected to the front end of the first positioning rod, abutting against the rear end of the second positioning rod. An adjusting bolt for driving the second positioning rod to move back and forth is threadedly connected inside the movable groove.

[0006] Furthermore, two mounting plates are fixedly connected to the bottom of the two movable blocks.

[0007] Furthermore, one end of each of the two mounting plates is fixedly connected to the top two ends of the lower fixing ring.

[0008] Furthermore, the outer wall of the hexagonal sliding column is slidably connected to a fixing ring that is fixedly connected to the middle of the inner side of the positioning through groove.

[0009] Furthermore, a return spring is sleeved on the outer wall of the rear end of the positioning through groove, and the two ends of the return spring are fixedly connected to the front end of the first positioning rod and the rear wall surface of the fixing ring, respectively.

[0010] Furthermore, the outer wall of the end of the adjusting bolt is threaded with an adjusting nut that is fixedly installed with the inner front end of the movable through groove.

[0011] Furthermore, the rear end of the adjusting bolt is fixedly installed with the front end of the second positioning rod.

[0012] Furthermore, both the upper and lower fixing rings have rubber pads fixedly connected inside.

[0014] Beneficial effects:

[0015] 1. This chemical equipment pipeline anti-breakage protection mechanism, through the setting of a positioning mechanism, in use, first inserts the movable block on the top end of the lower fixed ring into the movable groove, and then tightens the adjusting bolt. Due to the threaded installation between the adjusting bolt and the adjusting nut, the adjusting bolt drives the second positioning rod to move backward and insert into the front end of the positioning through groove. The rear end of the second positioning rod pushes the hexagonal sliding column, which drives the first positioning rod to move backward and insert into the positioning slot, thus stretching the return spring. This causes the mounting bracket and the movable block to rotate around the first and second positioning rods as the axis, thereby making the upper fixed ring... Pre-installation is completed by rotating one end of the upper and lower fixing rings together. The welded joint of the pipe is placed between the upper and lower fixing rings. The other end of the lower fixing ring is rotated to contact the other end of the upper fixing ring. The above operation is repeated to complete the connection between the other ends of the upper and lower fixing rings. The two ends of the upper and lower fixing rings are connected and fit over the welded joint of the pipe to form a stable protective effect. The upper and lower fixing rings can be easily disassembled by reversing the operation. The above operation is simple and practical, and the structure is reasonable and compact, which improves the stability of the equipment for fixing the pipe and enhances the practicality of the equipment.

[0016] 2. This chemical pipeline anti-breakage protection mechanism for chemical equipment, by setting a rubber pad, allows the upper and lower fixing rings to fit more tightly through the elasticity of the rubber pad, further improving the fixing effect of the equipment on the pipeline and improving the overall structural stability of the equipment.

[0024] A chemical pipeline anti-breakage protection mechanism for chemical equipment, such as Figure 1-4As shown, the device includes a straight rod 10, an upper fixing ring 11 fixedly mounted to the bottom of the straight rod 10, and a lower fixing ring 12 disposed at the bottom of the upper fixing ring 11. Mounting brackets 13 are symmetrically fixedly mounted at both ends of the bottom of the upper fixing ring 11. Movable grooves 14 are symmetrically opened in the middle of the two mounting brackets 13. Two movable blocks 15, fixedly mounted to the top ends of the lower fixing ring 12, are movably disposed inside the two movable grooves 14. Two positioning slots 17 are opened through the middle of the front wall of the two movable blocks 15. Two positioning slots 18 and two movable grooves 19, corresponding to the positions of the two positioning slots 17, are respectively opened on the front and rear side walls of the two movable grooves 14. A positioning mechanism is provided inside each of the two positioning slots 17. The positioning mechanism includes a first positioning rod 22 and a second positioning rod 26 slidably connected to the front and rear ends of the positioning slots 17, respectively. The ends of the first positioning rod 22 and the second positioning rod 26 that are far apart from each other are respectively inserted into the positioning slots 18 and the movable grooves 19. Inside, the front end of the first positioning rod 22 is fixedly connected to a hexagonal sliding column 21 that abuts against the rear end of the second positioning rod 26. The movable through groove 19 is threadedly connected to an adjusting bolt 25 for driving the second positioning rod 26 to move back and forth. The bottom of the two movable blocks 15 is fixedly connected to two mounting plates 16. One end of the two mounting plates 16 is fixedly connected to the top two ends of the lower fixing ring 12, respectively. The outer wall of the hexagonal sliding column 21 is slidably connected to a fixing ring 20 that is fixedly connected to the middle of the inner side of the positioning through groove 17. The outer wall of the rear end of the positioning through groove 17 is sleeved with a return spring 23. The two ends of the return spring 23 are fixedly connected to the front end of the first positioning rod 22 and the rear wall of the fixing ring 20, respectively. The outer wall of the end of the adjusting bolt 25 is threadedly installed with an adjusting nut 24 that is fixedly installed to the front end of the movable through groove 19. The rear end of the adjusting bolt 25 is fixedly installed to the front end of the second positioning rod 26. Both the upper fixing ring 11 and the lower fixing ring 12 are fixedly connected to rubber pads 27.

[0025] The working principle of this utility model is as follows: In use, first insert the movable block 15 at the top end of the lower fixing ring 12 into the movable slot 14. Tighten the adjusting bolt 25. Due to the threaded installation between the adjusting bolt 25 and the adjusting nut 24, the adjusting bolt 25 drives the second positioning rod 26 to move backward and insert into the front end of the positioning through slot 17. The rear end of the second positioning rod 26 pushes the hexagonal sliding column 21, causing the first positioning rod 22 to move backward and insert into the positioning slot 18, thus stretching the return spring 23. This causes the mounting bracket 13 and the movable block 15 to rotate and connect around the first positioning rod 22 and the second positioning rod 26 as the axis, thereby causing one end of the upper fixing ring 11 and the lower fixing ring 12 to rotate and connect, completing the pre-installation. Place the welded joint of the pipe on the upper fixing ring 11 and the lower fixing ring 12. Between the two fixing rings 12, rotate the other end of the lower fixing ring 12 to contact the other end of the upper fixing ring 11. Repeat the above operation to complete the connection between the other ends of the upper fixing ring 11 and the lower fixing ring 12. This connection between the two ends of the upper fixing ring 11 and the lower fixing ring 12 forms a stable protective effect at the welded joint of the pipe. The upper fixing ring 11 and the lower fixing ring 12 can be easily disassembled by reversing the operation. The above operation is simple and practical, and the structure is reasonable and compact, which improves the stability of the device for fixing the pipe and enhances the practicality of the device. The rubber pad 27, through its own elasticity, allows the upper fixing ring 11 and the lower fixing ring 12 to fit more tightly, further improving the fixing effect of the device on the pipe and enhancing the overall structural stability of the device.
