A pipeline steel flexible anti-seismic support

Abstract

The invention discloses a pipeline steel flexible anti-seismic support which comprises a main U-shaped support body, a supporting pillar, a pipeline sleeve and a steel wire rope. The middle of the bottom wall of the main U-shaped support body is fixedly connected with the supporting pillar. The pipeline sleeve comprises an upper pipe sleeve and a lower pipe sleeve which are arranged in an up-down aligning mode. The steel wire rope is symmetrically erected on the lower pipe sleeve and located at the two sides of connecting blocks. A hinged rod is arranged between a connecting rod and the upper pipe sleeve. One end of the hinged rod is fixedly connected with the connecting rod, and the end, far away from the connecting rod, of the hinged rod is connected with the upper pipe sleeve in a rotating mode. A mounting groove is formed in the lower pipe sleeve and corresponds to the supporting pillar. Radial springs are fixed between the supporting pillar and the side wall of the mounting groove in the radial direction of the pipeline sleeve. Axial springs are fixed between the supporting pillar and the side wall of the mounting groove in the axial direction of the pipeline sleeve. According to the pipeline steel flexible anti-seismic support, the pipeline sleeve can be supported through a rigid supporting piece and a flexible supporting piece at the same time, the supporting effect on the pipeline sleeve by the whole support is better, and the anti-seismic action is made better and more effective.

Description

technical field [0001] The invention relates to the technical field of anti-seismic support, in particular to a pipeline steel flexible anti-seismic support. Background technique [0002] In many places where pipelines need to be installed, multi-section pipeline splicing is used to achieve long-distance transportation. Therefore, in order to make the structure of the splicing more stable, a bracket must be installed at the splicing of the pipeline. This bracket usually includes mechanical joints connecting two pipes ( That is, the pipe sleeve), and the support used to connect the pipe sleeve. [0003] In order to provide sufficient support for the pipe sleeve, the support is generally directly connected to a permanent structure, such as the ceiling. In the prior art, the support can be divided into two types according to the steel flexibility of the support: 1. Steel support; 2. Flexible bracket. [0004] For the existing two supports, there are obviously the following de...

Problems solved by technology

[0004] For the existing two supports, there are obviously the following defects: 1. When only rigid supports are used, although the rigid support will provide a sufficient supporting force for the pipe sleeve, when an earthquake or any impact force acts When it is attached to the pipeline, the pipe sleeve may produce a reaction force on the rigid support, causing rigid fracture of the rigid support, resulting in damage to the entire support; 2. When only using flexible supports, flexible supports such as steel wire ropes will not Rigid fracture occurs, but it is difficult to provide sufficient support for the pipe sleeve, and a large amount of steel wire rope is required to provide support, which is a waste of material
