Description

Technical field:

[0001] The utility model relates to the technical field of pipeline support, in particular to a support structure for branch pipelines. Background technology:

[0002] At present, main pipelines with large deformation, such as steam pipelines, generally use spring supports as fixed supports for the main pipelines. Small-diameter branch pipelines are usually set horizontally on the steam pipelines for other purposes, so brackets are usually not set for support.

[0003] The current problem is: during the use of the steam pipe, the deformation of the steam pipe due to thermal expansion and contraction is much greater than the deformation of the branch pipe, which causes high-frequency vibration in the branch pipe. Long-term high-frequency vibration can easily cause cracks in the welds at the connection between the branch pipe and the steam pipe, posing a safety hazard to the surrounding environment. Utility model content:

[0004] The purpose of the present invention is to provide a support structure for branch pipes to solve the problems raised in the above background technology.

[0005] The utility model is implemented by the following technical solutions:

[0006] A support structure for branch pipes, including a steam pipe, multiple branch pipes are horizontally fixed on the surface of the steam pipe, and multiple support structures equal to the number of branch pipes are fixed on the outer surface of the steam pipe, the support structure includes a first clamp, a second clamp, a limit baffle, a support pipe and a tension spring in a C-shaped structure; the first clamp and the second clamp are fixed to the steam pipe by bolts, a through hole is opened in the middle position of the surface of the first clamp, so that the branch pipe passes through the through hole, two first lifting ears distributed up and down are fixed on the outer surfaces of the two sides of the first clamp relatively away from the through hole, two vertically arranged limit baffles are horizontally distributed on the outer surfaces of the two sides of the first clamp relatively close to the through hole, a support pipe is provided on the outer surface of the branch pipe that passes through, and two second lifting ears distributed up and down are fixed on the middle outer surface of the support pipe, and the adjacent first lifting ears and second lifting ears are connected by a tension spring.

[0007] Preferably, the support tube is movably placed between two limit baffles.

[0008] The advantages of the utility model are: the first clamp and the second clamp are fixed to the steam pipe in a fixed relative position, and the support pipe is kept fixed relative to the steam pipe under the pulling of the two tension springs in opposite directions, and the branch pipe is supported by the support pipe; thereby greatly reducing the vibration frequency of the branch pipe, effectively extending the time period for cracks to appear at the connection between the branch pipe and the steam pipe, extending the service life of the branch pipe, and reducing safety hazards to the surrounding environment.

[0013] See also Figure 1-2 , the utility model provides a technical solution for a support structure of a branch pipeline:

[0014] A support structure for branch pipes, including a steam pipe 1, with multiple branch pipes 2 fixed horizontally on the surface of the steam pipe 1, and multiple support structures equal to the number of branch pipes 2 fixed on the outer surface of the steam pipe 1, the support structure including a first clamp 3, a second clamp 4, a limit baffle 5, a support pipe 6 and a tension spring 7 in a C-shaped structure; the first clamp 3 and the second clamp 4 are fixed to the steam pipe 1 by bolts, and a through hole 3.1 is opened in the middle position of the surface of the first clamp 3, so that the branch pipe 2 passes through the through hole 3.1, and two first hanging ears 3.2 distributed up and down are fixed on the outer surfaces of the two sides of the first clamp 3 relatively away from the through hole 3.1, and two vertically arranged limit baffles 5 are horizontally distributed on the outer surfaces of the two sides of the first clamp 3 relatively close to the through hole 3.1, and a support pipe 6 is slidingly sleeved on the outer surface of the branch pipe 2 that passes through, and the support pipe 6 is movably placed between the two limit baffles 5, so that when the steam pipe 1 is deformed, the branch pipe 2 cannot swing horizontally.

[0015] Two second lifting ears 6.1 distributed upper and lower are fixed to the middle outer surface of the support tube 6, and the adjacent first lifting ears 3.2 and second lifting ears 6.1 are connected by a tension spring 7, so that when the steam pipe 1 is deformed, the first clamp 3 and the second clamp 4 remain stationary relative to the steam pipe 1, and under the pulling of the two upper and lower tension springs 7 in opposite directions, the support tube 6 remains stationary relative to the steam pipe 1. At the same time, since the branch pipe 2 remains stationary relative to the support pipe 6, the branch pipe 2 is supported by the support pipe 6; thereby greatly reducing the vibration frequency of the branch pipe, effectively extending the time period for cracks to occur at the connection between the branch pipe and the steam pipe, extending the service life of the branch pipe, and reducing safety hazards to the surrounding environment.

[0016] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
