Problems solved by technology

However, when the device is subjected to severe impact loads, it is easily damaged and has poor impact resistance.
[0004] At present, there are no shock-resistant components and standard hangers to choose from in my country, and the standards and specifications for the impact-resistant design of pipeline systems, the development and layout of impact-resistant components, and the impact test acceptance of pipeline systems are still blank.

Embodiment example 1

[0027] Implementation case 1: When the pipeline installation needs to be arranged in a suspended manner according to the space characteristics, such as figure 1 and figure 2 Shown, be a kind of pipeline hanger of the present invention for marine vibration damping and impact resistance, by pipeline 1, wire mesh washer 2, movable baffle 3, shock absorber 4, damping metal sticking board 5, non-slip rubber pad 7, pipe Card 8, bracket 6, small spring 9, elastic body 10, sealing ring 11, large spring 12, damping cylinder 13, piston rod 14, piston cylinder 15, damping piston 16, damping liquid 17, sealing ring 2 18, barrel Cover 19, shell 20 are formed.

[0028] A movable baffle 3 attached to the pipeline 1 is arranged between the pipeline 1 and the bracket 6 , and the other plane of the movable baffle 3 is provided with a shock absorber connected to the bracket 6 through a non-slip rubber pad 7 . A wire mesh gasket 2 is also arranged between the pipeline 1 and the pipe clip 8; th...

Embodiment example 2

[0036] Implementation case 2: Large-diameter pipeline work is also required in the ship pipeline system due to working conditions, such as image 3 As shown, the implementation of the present invention relates to the installation method of large-diameter pipelines in the ship pipeline system. During work, the wire mesh gasket 2 wraps the pipeline 1 and places it on the plane of the movable baffle 3. On the other plane of the movable baffle 3, a shock absorber 4 connected to the bracket 6 is placed on the other plane of the movable baffle 3. Anti-slip rubber pad 7 is installed between 6 and shock absorber 4 to keep the balance and stability of shock absorber 4; when the pipeline vibrates, it passes through movable baffle 3 and is transmitted to piston rod 14, pushing damping piston 16 to compress damping fluid 17 , through the through hole at the lower end of the piston cylinder 15, it flows into the gap cavity between the piston cylinder 15 and the damping cylinder 13, and the...

Abstract

The invention discloses a damping type elastic pipe hanger for marine damping, vibration reduction and impact resistance, which includes a U-shaped pipe clip set on the pipe and a bracket for fixing and installing the pipe clip. A movable baffle is arranged between the brackets and attached to the pipe, and on the other plane of the movable baffle, a shock absorber connected with the bracket is arranged through a non-slip rubber pad; between the pipe and the pipe clamp There is also a wire mesh gasket between them. The invention has the advantages of simple structure, low cost and good effect of vibration reduction and impact resistance, which improves the safety of the pipeline and prolongs the service life of the pipeline; moreover, the invention has the advantages of simple and compact structure, low cost and convenient installation. It has good engineering application prospect.

Description

technical field [0001] The invention relates to the field of ship vibration reduction, in particular to a pipeline hanger structure with good vibration reduction and impact resistance on the ship. Background technique [0002] The vibration problem of the ship power transmission piping system has a broad engineering background, and is an important factor affecting the safety performance of the ship engine room. As the transport body of oil, water, gas and other fluids between various power The power equipment is connected and arranged in the engine room of the ship. The vibration of the pipeline due to various reasons seriously affects the service life of the piping system and threatens the safety of the engine room of the ship. Since the two factors of liquid pressure pulsation and pipe wall structure vibration exist in the transportation piping system, as well as the fluid-solid coupling during the transportation process, they will become important factors for the vibratio...
