Seismic bracing

Abstract

The invention provides a seismic bracing. The seismic bracing comprises an anchoring part, a vertical bearing hanging rod, an inclined supporting rod, a pipe bundle and a cable-stayed connecting piece, the pipe bundle comprises connecting plates, connecting rods, an upper pipe clamp, a lower pipe clamp and a lower bottom plate, the cable-stayed connecting piece comprises a U-shaped rod, a pin roller and a first fixing plate, the first connecting plates are fixed to the two ends of the inclined supporting rod correspondingly, the first connecting plate at the lower end of the inclined supporting rod is fixed to the first fixing plate, and the first connecting plate at the upper end of the inclined supporting rod is fixed to the anchoring part. According to the seismic bracing, the angle of the inclined supporting rod can be flexibly adjusted and controlled, and good damping effect is achieved while mounting and fixing are convenient; and the device is suitable for pipelines with different pipe diameters, the application range of the device is widened, and meanwhile unified production is facilitated.

Description

technical field [0001] The invention relates to the technical field of hangers, in particular to an anti-seismic hanger. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. The most harmful natural disaster to the pipeline is the earthquake. During the earthquake, the pipeline is easily shaken and shaken, which will cause the pipeline to rupture, causing leakage and loss. If the leakage is oil or natural gas, it will not only cause environmental pollution, but also may Cause fire, bring great harm to people. Therefore, in the pipeline installation process, people usually add anti-seismic hangers to the pipeline to reduce the impact of earthquakes on the pi...

Problems solved by technology

First, the cable-stayed connectors of seismic support hangers in the prior art often use multi-directional connectors, which are fixed on the tube bundles, and the vertical load-bearing suspenders and diagonal braces to be connected are fixed on multiple directional connectors, but the connection strength is low, and it is easy to deform when vibration occurs, and the vertical load-bearing suspenders and diagonal braces are rigidly connected to the tube bundle, so it cannot achieve a good seismic effect, and the multi-directional connectors The angles of the diagonal braces connected in each direction are often fixed, and the installation is not easy. When the installation plane is small, the diagonal braces with fixed angles cannot be used, and the method of setting the diagonal braces on one side is often used, which leads to the installation of seismic supports and hangers. unstable, tilts

Second, due to the different diameters of the pipelines used to transport materials, the existing anti-seismic support hangers often use fixed-structure tube bundles. When the fixed-structure tube bundles are in use, the inner diameter of the tube bundles is fixed. , cannot be applied to pipes of different sizes. When the diameter of the pipe bundle does not match the pipe, it is necessary to disassemble and install a new pipe bundle that matches it. Pipe bundles of different diameters are used for installation of different pipes. Some pipe bundles of non-standard sizes even need to be customized. The production is complicated and cannot be produced uniformly.
