Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the specific drawings.

As shown in FIGS. 1-5,

when the natural gas pipeline vibration damping device works, the support frame 1 can be fixed through the fixing column 17, then a natural gas pipeline is placed inside the support frame 1, the natural gas pipeline is supported by the vibration damping seat 9, meanwhile, the fixing clamping ring 2 is placed at the top end of the support frame 1, and the natural gas pipeline and the support frame 1 are fixed through the fixing screw 18, so that the fixing clamping ring 2 can fix the natural gas pipeline, when the natural gas pipeline vibrates, the natural gas pipeline applies pressure to the vibration damping seat 9 to enable the natural gas pipeline to slide inside the support frame 1, and the vibration damping is applied to the second vibration damping spring 13 through the positioning column 12, so that the vibration force transmitted by the vibration damping seat 9 can be buffered by the second vibration damping spring 13, the vibration of the natural gas pipeline can be reduced, wherein the second vibration damping spring 13 can be well limited through the sliding plate 14, so that the bottom of the support frame 1 is not easy to wear, and through the combination of the second limiting bulge 10 and the second limiting chute 11, the shock absorption seat 9 can be effectively prevented from position deviation during sliding, the normal work of the device is prevented from being influenced, secondly, when the natural gas pipeline vibrates, the vibration force at the top of the pipeline can be well buffered through the combination of the limiting snap ring 5 and the first damping spring 8, so that the vibration force of the pipeline is reduced, and through the combination of the sliding rod 4 and the limiting plate 20, the limiting snap ring 5 can be effectively prevented from being separated from the inner bottom end of the sliding sleeve 3 during moving, meanwhile, through the combination of the first limiting bulge 6 and the first limiting chute 7, the position of the limiting snap ring 5 can be well limited, so that the limiting snap ring is not easy to rotate during working, the shock absorption effect of the limiting snap ring 5 on the pipeline is prevented from being influenced, the device is practical, and the surface of the pipeline can be well protected through the rubber protective layer 15, the pipeline is not easy to rub against the device when being vibrated, and the pipeline is prevented from being damaged.
