[0002] Flange is a part that connects shafts to each other and is mainly used for connecting pipe ends. The flange sleeve is easily vibrated by the impact of the external environment during use. Long-term vibration of the flange can easily cause the bolts that fix the flange to loosen. A vibration absorbing device can be installed on the flange surface to absorb and reduce the vibration caused by the impact on the flange, thereby achieving vibration reduction of the flange.
[0003] The existing flange-connected vibration absorbing device is prone to fatigue damage after a long period of vibration reduction on the flange, and needs to be disassembled, repaired and replaced regularly. Since the vibration absorbing device is generally directly welded and fixed to the flange surface, it cannot be disassembled at will. Therefore, modification is required. Utility Model Content

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a flange-connected vibration absorbing device, comprising a flange sleeve 1, six groups of limit strips 2 are fixedly installed at equal angles on the surface of the flange sleeve 1, six groups of connecting holes 3 are provided at equal angles on the surface of one end of the flange sleeve 1, and a fixing hole 4 is provided on the surface of one end of the flange sleeve 1 between two adjacent groups of connecting holes 3. Because of the fixing hole 4, after the fixing stud 8 on one side of the mounting frame 5 is passed through the corresponding fixing hole 4, the fixing nut 9 is tightened to clamp the fixing stud 8 inside the fixing hole 4, thereby installing and fixing the mounting frame 5 on the surface of the flange sleeve 1, ensuring that the mounting frame 5 will not deflect arbitrarily on the surface of the flange sleeve 1.
[0021] A mounting frame 5 is provided on the surface of the flange sleeve 1, and six groups of fixing studs 8 are fixedly installed at equal angles on both sides of the mounting frame 5. The fixing studs 8 pass through the fixing holes 4 and a fixing nut 9 is provided on one side of the fixing pressure ring 10. By providing the fixing nut 9, after the fixing stud 8 passes through the corresponding fixing hole 4 and the fixing pressure ring 10, the fixing nut 9 is tightened to connect and fix the flange sleeve 1, the mounting frame 5 and the fixing pressure ring 10.
[0022] Six groups of mounting grooves 6 are provided at equal angles on the surface of the mounting frame 5, and T-shaped slots 7 are symmetrically provided on both sides of the inner wall of the mounting groove 6, and the T-shaped slots 7 correspond to the T-shaped inserting strips 13. Because the T-shaped slots 7 and the T-shaped inserting strips 13 are provided, when the mounting plate 12 is inserted into the mounting groove 6, the T-shaped inserting strips 13 are inserted into the corresponding T-shaped slots 7 to ensure that the mounting plate 12 will not shake at will when it is stuck in the mounting groove 6.
[0023] A fixed pressure ring 10 is provided on one side of the mounting frame 5, and six groups of limiting grooves 11 are provided at equal angles on the inner wall of the fixed pressure ring 10, and the limiting grooves 11 correspond to the limiting strips 2. By providing the limiting grooves 11 and the limiting strips 2, when the fixed pressure ring 10 is sleeved on the surface of the flange sleeve 1, the limiting grooves 11 are stuck on the corresponding surface of the limiting strips 2 to ensure that the fixed pressure ring 10 is stuck on the surface of the flange sleeve 1 and will not rotate at will.
[0024] A mounting plate 12 is provided inside the mounting groove 6, and T-shaped inserts 13 are symmetrically fixedly installed on both sides of the mounting plate 12. Three groups of vibration dampers 14 are equidistantly inlaid and fixedly installed inside the mounting plate 12, and a vibration damper rod 15 is slidably installed inside the vibration damper 14. Because the vibration damper 14 is provided, the vibration damper rod 15 slides inside the vibration damper 14, so that the vibration damper 14 rubs on the surface of the vibration damper rod 15, thereby realizing the consumption of the elastic potential energy of the vibration damper spring 18, and achieving the effect of vibration reduction;
[0025] One end of the three groups of vibration-damping rods 15 passes through the vibration-damping damper 14 and is fixedly installed with a connecting plate 16, and one end of the three groups of vibration-damping rods 15 away from the connecting plate 16 is fixedly installed with a vibration-damping plate 17. The side of the vibration-damping plate 17 away from the vibration-damping rod 15 is in an arc shape and corresponds to the surface of the flange sleeve 1. Because the vibration-damping plate 17 is provided, the arc surface of the vibration-damping plate 17 is closely attached to the surface of the flange sleeve 1, thereby increasing the contact area between the vibration-damping plate 17 and the flange sleeve 1, and ensuring that the vibration of the flange sleeve 1 can be transmitted to the vibration-damping rod 15 through the vibration-damping plate 17 to the maximum extent.
[0026] A damping spring 18 is provided on the surface of the damping rod 15 between the mounting plate 12 and the damping plate 17 . The damping spring 18 is squeezed and rebounded between the mounting plate 12 and the damping plate 17 , thereby pressing the damping plate 17 against the surface of the flange sleeve 1 .
[0027] The working principle of the utility model is:
[0028] After the fixing nut 9 is removed from the surface of the fixing stud 8, the mounting frame 5 is correspondingly sleeved on the surface of the flange sleeve 1 so that the fixing stud 8 can pass through the corresponding fixing hole 4, and the fixing nut 9 is tightened to clamp and fix the fixing stud 8 inside the fixing hole 4, thereby clamping and fixing the mounting frame 5, and pulling the connecting plate 16 to control the vibration reduction plate 17 to approach the mounting plate 12, inserting the mounting plate 12 into the mounting groove 6, so that the T-shaped insert 13 can be inserted into the corresponding T-shaped slot 7, until the six groups of mounting plates 12 are respectively inserted into the bottom of the corresponding mounting groove 6, and then the connecting plate 16 is loosened. Under the rebound effect of the vibration reduction spring 18 Press the vibration damping plate 17 onto the surface of the flange sleeve 1, and put the fixing pressure ring 10 onto the surface of the flange sleeve 1 and close to one side of the mounting frame 5, so that the fixing stud 8 passes through the fixing pressure ring 10, and tighten the fixing nut 9 to clamp and fix the mounting plate 12 inside the mounting groove 6. When the flange sleeve 1 vibrates, the vibration pushes the vibration damping plate 17 to approach the mounting plate 12 through the vibration damping plate 17, so that the vibration damping spring 18 is squeezed and rebounded to deform, and the vibration damping rod 15 is driven to slide inside the vibration damping 14. Under the friction effect of the vibration damping 14 on the vibration damping rod 15, the elastic potential energy of the vibration damping spring 18 is consumed, thereby absorbing the vibration of the flange sleeve 1.
[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
[0030] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
