Detailed Description

example 1

As shown in fig. 1, the present embodiment discloses a belleville spring pipe clamp, including: support body 1, fastening nut subassembly 2, support bottom plate 3 and dish spring elastic structure 456, support body 1 includes: two longitudinal connecting rods 11 and a transverse connecting rod 12 connecting the two longitudinal connecting rods; the two longitudinal connecting rods 11 are respectively and fixedly connected with the bracket bottom plate 3 through the fastening nut components 2; the pipeline passes through the space between the bracket body 1 and the bracket bottom plate 3; the plurality of disc spring elastic structures 456 are connected with one side of the bracket body 1/the bracket bottom plate 3 facing the pipeline, and the plurality of disc spring elastic structures 456 are circumferentially arranged to clamp and fix the pipeline; the disc spring elastic structure 456 counteracts the impact force on the pipeline by compression/restoration; the amount of pretension and the compression stroke of the disc spring elastic structure 456 are adjusted by tightening the nut assembly 2.

Specifically, the disc spring elastic structure is used for stably clamping the pipeline, and strong impact force generated when the marine power system and the boiler system run is buffered through the elastic structure, so that the pipeline is prevented from being damaged. The core component of the disc spring elastic structure 456 is a disc spring, the disc spring has the characteristics of short stroke, large load, small required space, convenience in combination and use and easiness in maintenance and replacement, a marine pipe clamp cannot select a spring with overlarge elasticity, impact force generated when a marine power system and a boiler system operate is very strong, the stability of a clamping pipeline is influenced when the elasticity of the spring is overlarge, and the pipeline is damaged when the elasticity of the spring is overlarge. The disc spring can bear extremely large load in a small space, has good buffering and shock absorbing capacity, and particularly has more remarkable effects of absorbing impact and dissipating energy due to the surface friction resistance effect when the disc spring is combined in a folding mode. Furthermore, the size of each disc of the disc spring is not large, which facilitates manufacturing and heat treatment, and when some discs are damaged, only individual replacement is required, thereby facilitating maintenance and repair. The number of the disc spring elastic structures 456 can be more than one, but 3 or 4 are usually enough to stably clamp the pipeline, 3 or 4 pipe clamps are adopted, which are mainly determined by the outer diameter of the pipeline, and 3 disc spring elastic structures 456 are easily adopted when the outer diameter of the pipeline is phi 22-phi 76; when the outer diameter of the pipe is phi 89-phi 325, 4 pipe clamps with disc spring elastic structures 456 are easy to adopt.

The main effect of the fastening nut component 2 is to adjust the pre-tightening amount and the compression stroke of the disc spring elastic structure 456, because when the fastening nut component 2 is screwed, the bracket body 1 is driven to move towards the bracket bottom plate 3, so that the disc springs on the disc spring elastic structure 456 on the bracket body 1 and the bracket bottom plate 3 are compressed, and meanwhile, the pipeline can be clamped more tightly. However, the compression stroke of the disc spring is shortened due to the over-tight clamping pipeline, and the effect of dissipating stress of the disc spring is influenced due to the over-short clamping pipeline; but also can not be clamped too loosely so as to avoid influencing the effective fixation of the pipeline, therefore, the disk spring is kept to have a certain compression stroke by reasonably adjusting the pre-tightening amount of the fastening nut component 2 on the premise of effectively fixing the pipeline, and the effect of buffering and absorbing shock of the pipeline can be achieved. The pre-tightening amount is within the range of 3-5 mm and the compression stroke is within the range of 3-6 mm according to data obtained by tests, so that the effect can be achieved. The two longitudinal connecting rods 11 are provided with pre-tightening position lines, and the pre-tightening amount can be adjusted through the fastening nut component 2 according to the pre-tightening position lines during field installation. If the pipeline is dismantled, under the ordinary condition, need not to carry out secondary pretension, avoid influencing pipe clamp because of secondary pretension and eliminate the thermal expansion stress effect.

As shown in fig. 3-6, the tightening nut assembly 2 additionally functions to secure the pipe clamp to the cleat or bulkhead of the vessel.
