Metal elastic suspension

Abstract

The invention discloses a metal elastic suspension which comprises a sleeve (5), a tension and compression rod (9) and a spiral rod (4), wherein one end of the tension and compression rod (9) is connected with a hoisting element, and the other end of the tension and compression rod (9) extends into the sleeve (5) through an opening at the upper end of the sleeve (5) to be fixedly connected with a cushion block (6); a steel wire gauze pad (7) and a spring (8) are arranged between the upper end of the sleeve (5) and the cushion block (6); the steel wire gauze pad (7) is arranged at the periphery of the tension and compression rod (9); the spring (8) is sleeved on the steel wire gauze pad (7); one end of the spiral rod (4) is connected with the hoisting element, and the other end of the spiral rod (4) is fixed on the lower end part of the sleeve (5). The metal elastic suspension provided by the invention has the advantages that structure is simple, installation is convenient, environment adaptability is strong, and the like; and pipeline damage caused by pipeline vibration is reduced, and meanwhile, noise caused by pipeline vibration can be reduced.

Description

technical field [0001] The invention relates to a metal elastic hanger, which is used for the vibration-isolation support of the diesel engine exhaust pipeline to fix the pipeline and avoid the vibration of the pipeline, especially for the hoisting of the horizontal pipeline. Background technique [0002] The continuous expansion of trade globalization has led to the continuous growth of the shipping industry. In order to maximize the carrying capacity of a single ship, shipyards continue to increase ship power during shipbuilding, and the power comes directly from diesel engines. In addition, in order to provide heat sources, they will be equipped with Oil-fired boilers, only diesel engines and boilers, will produce a large amount of exhaust gas, which requires an exhaust system to smoothly discharge the exhaust gas generated by the two overboard. The main component of the exhaust system is the exhaust pipe; Trouble-free exhaust pipelines are a crucial prerequisite to ensur...

[0002] The continuous expansion of trade globalization has led to the continuous growth of the shipping industry. In order to maximize the carrying capacity of a single ship, shipyards continue to increase ship power during shipbuilding, and the power comes directly from diesel engines. In addition, in order to provide heat sources, they will be equipped with Oil-fired boilers, only diesel engines and boilers, will produce a large amount of exhaust gas, which requires an exhaust system to smoothly discharge the exhaust gas generated by the two overboard. The main component of the exhaust system is the exhaust pipe; Trouble-free exhaust pipelines are a crucial prerequisite to ensure the normal operation of diesel engines and boilers. However, the pipelines are affected by the outside world and the flow of internal media to produce varying degrees of vibration, and are even affected by their own thermal expansion. The vibration of the flange can cause the loosening of the flange connection, resulting in the leakage of the pipeline medium, and the pipeline itself will also produce fatigue damage, which will affect the service life
