Embodiment Construction
[0020] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0021] Such as figure 1 and figure 2 As shown, the present invention provides a pipeline vibration-isolation and shock-resistant elastic support hanger, including a vulcanized clamp, a support 5 and a dynamic vibration-absorbing assembly;
[0022] The vulcanized clamp is a ring structure, which is formed by connecting the upper half ring 1 of the vulcanized clamp and the lower half ring 3 of the vulcanized clamp through bolts I2. The upper half ring 1 of the vulcanized clamp and the lower half ring 3 of the vulcanized clamp are two A semi-circular clamp ring, the inner diameter of the vulcanized clamp is consistent with the outer diameter of the pipeline, and the inner side of the vulcanized clamp is vulcanized rubber. When the pipeline is fixed in the vulcanized clamp, the vulcanized rubber is in close contact with the pipeline to realize the pipeline ...

The invention discloses a pipeline vibration-insulation antishock elastic supporting suspension rack comprising a vulcanization clamp, a supporting member and a power dynamic absorbing assembly. The vulcanization clamp is in a circular ring structure; the supporting member is in a 8-shaped structure and consists of an upper steel ring and a lower steel ring; the upper and lower steel rings are fixedly connected with each other; the power vibration absorbing assembly is formed by a quality block, an upper frequency modulation spring, a lower frequency modulation spring and an adjusting stud; the adjusting stud orderly passes through the upper frequency spring, the quality block and the lower frequency adjusting spring; the bottom of the lower steel ring of the supporting member is fixedly connected to a base seat; the top of the upper steel ring of the supporting member is connected with the vulcanization clamp via a bolt; the upper end of the adjusting stud of the power vibration absorbing assembly is fixedly connected to the middle of the supporting member; and the supporting suspension rack can effectively prevent pipeline vibration transmitting to a ship body structure. Upon external impact to a ship, impact stress to the system pipeline by the external impact and damage can be effectively reduced by elasticoplastic deformation of the elastic support, so system integrity and reliability can be guaranteed.
Description
technical field [0001] The invention belongs to the technical field of vibration and noise control, and in particular relates to a pipeline vibration-isolation and shock-resistant elastic support and hanger. Background technique [0002] There are many system pipelines on the ship, which are widely arranged in the internal space of the ship in a network shape, and become the arteries and blood vessels to ensure the normal operation of the ship. Since the system pipeline is connected with the power equipment, the system pipeline has become the most important channel for the vibration transmission of mechanical equipment after the large-scale vibration damping device is widely used in the power equipment. At present, in the design of pipeline vibration and noise control, the method of setting flexible pipe joints and pipeline elastic supports is mainly used to effectively isolate the vibration and radiation noise caused by the vibration transmission of the system pipeline. The...
