[0002] The expansion joint is also called compensator or expansion joint in the habit, is composed of the corrugated pipe (a elastic element) of constituting its work main part and end pipe, support, flange, guide pipe and the like accessories. Expansion joint is a flexible structure arranged on the vessel shell or pipeline to compensate additional stress caused by temperature difference and mechanical vibration. The effective expansion and contraction of the corrugated pipe, the working main body, is used to absorb the size change of pipeline, guide pipe, vessel and the like caused by thermal expansion and contraction, or compensate the axial, lateral and angular displacement of pipeline, guide pipe, vessel and the like. It can also be used for noise reduction and shock absorption, heat supply. In order to prevent the deformation or damage of the pipeline due to thermal elongation or temperature stress when the heating pipeline is heated, a compensator needs to be arranged on the pipeline to compensate the thermal elongation of the pipeline, thereby reducing the stress of the pipeline wall and the force acting on the valve or support structure. When the compensator is working, a stable environment is needed. External vibration or vibration generated by the compensator during operation can cause the corrugated pipe to leak due to fatigue after long-term use, thereby shortening the service life of the compensator.

However, when the compensator is in use, the medium fluid flowing through the corrugated pipe can easily cause the corrugated pipe at the medium inflow end of the compensator to be stretched, and the corrugated pipe at the medium outflow end of the compensator to be compressed. In addition, the pressure of the medium fluid in the corrugated pipe on the pipe wall, the stress on the corrugated pipe body is not weakened, so that the corrugated pipe at the wave crest or wave trough is still prone to leakage due to fatigue when subjected to vibration, thereby reducing the shock absorption effect.

[0021] In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific implementation, structure, features and effects according to the utility model are described in detail as follows in combination with the drawings and preferred embodiments.
[0022] Please refer to Figs. 1-3 The utility model provides a kind of technical scheme: a compensator shock absorbing base, including bottom plate 1, support part 2, connecting part 3, first spring 41 and second spring 42, the support part 2 is two, two support part 2 is connected on the bottom plate 1 upper end surface, two support part 2 is used to support the both ends pipe 82 of compensator, the connecting part 3 is multiple, multiple connecting part 3 upper end one-to-one corresponding connection the multiple wave crest outer surfaces of the bellows 81 of compensator, multiple connecting part 3 lower end can all be slidably connected bottom plate 1, first spring 41 is located between adjacent two connecting part 3, the both ends of first spring 41 are connected with adjacent two connecting part 3 respectively, second spring 42 is two, one end of two second spring 42 is connected with two outermost connecting part 3 in the arrangement direction of multiple connecting part 3 respectively, the other end of two second spring 42 is connected with two support part 2 respectively.
[0023] When the compensator shock absorbing base of the utility model is used to shock-absorb compensator, first, the end pipe 82 of compensator is placed on the support part 2, so that the support part 2 supports the whole compensator, then the connecting part 3 is used to connect the wave crest outer surface of the bellows 81 of compensator, so that when the bellows 81 of compensator is extruded or stretched, the displacement of the position where the wave crest is located can drive the displacement of the connecting part 3, since the both ends of first spring 41 are connected with adjacent two connecting part 3 respectively, when the displacement of two adjacent wave crests of the bellows 81 of compensator occurs, the displacement of wave crest drives the displacement of connecting part 3 to generate extrusion or stretching to first spring 41, since first spring 41 elastically supports the stretching or shortening of the wave crest of the bellows 81 of compensator, it can make the bellows 81 of compensator not excessively elongate at inflow end or excessively compress at outflow end due to the lack of elastic support of the wave crest of the bellows 81 of compensator when the bellows 81 of compensator is impacted by medium fluid, so as to weaken the stress on the pipe body of the bellows 81 of compensator, to a certain extent, reduce the possibility that the wave crest or wave trough of the bellows 81 of compensator is still prone to leakage due to fatigue when it is vibrated, and to a certain extent, improve the shock-absorbing effect.
[0024] In the embodiment, the connecting part 3 comprises two abutting blocks 31 and a torsion spring 32. The two abutting blocks 31 are oppositely arranged, and the upper ends of the two abutting blocks 31 abut the two side surfaces of the outer surface of the wave crest of the corrugated pipe 81 of the compensator.

[0025] Since the lower ends of the two abutting blocks 31 are rotatably connected to the bottom plate 1, and the two ends of the torsion spring 32 are connected to the lower ends of the two abutting blocks 31, the upper ends of the two abutting blocks 31 can be pushed away from each other. When the corrugated pipe 81 needs to be connected, the two abutting blocks 31 are first pushed to rotate, so that the upper ends of the two abutting blocks 31 are away from each other, the distance between the upper ends of the two abutting blocks 31 is increased, until the distance between the upper ends of the two abutting blocks 31 is sufficient to place the corrugated pipe 81 of the compensator, at this time the torsion spring 32 is compressed due to the pushing force of the two abutting blocks 31. Then, the position of the wave crest of the corrugated pipe 81 of the compensator is aligned with the position of the two abutting blocks 31, and then the two abutting blocks 31 are released. The torsion spring 32 drives the abutting blocks 31 to rotate towards the corrugated pipe 81 of the compensator due to the cancellation of the pressure of the abutting blocks 31 on the torsion spring 32, until the upper ends of the two abutting blocks 31 abut the two side surfaces of the outer surface of the wave crest of the corrugated pipe 81 of the compensator.

[0030] In the embodiment, the recessed surface of the abutting block 31 is provided with a non-slip pad 7, and the non-slip pad 7 can be a soft ceramic fiber non-slip pad 7. With the structure, the possibility of scratching the outer wall of the corrugated pipe 81 of the compensator by the abutting block 31 can be reduced to a certain extent, and the service life of the corrugated pipe 81 of the compensator can be ensured to a certain extent.
