Anti-earthquake support system provided with steel wire ropes and used for rectangular air pipe

Abstract

The invention discloses an anti-earthquake support system provided with steel wire ropes and used for a rectangular air pipe. The anti-earthquake support system provided with the steel wire ropes andused for the rectangular air pipe comprises a lower support, wherein the rectangular air pipe is placed on the lower support, and L-shaped limit plates are arranged at the two sides of the rectangularair pipe; a rubber push plate is arranged below a rubber rod, and a earthquake absorption spring is arranged between the rubber push plate and an upper support in a connection manner; the upper support is symmetrically provided with fixing blocks at the two sides of the rubber push plate, an L-shaped piston cavity is formed in each fixing block, and a second clamping rod is fixedly arranged at one side away from the corresponding L-shaped piston cavity, of a second piston plate; an annular plate is fixedly arranged at the outer side of a connection element, and a plurality of thread holes areformed in the annular plate; and the steel wire ropes are symmetrically arranged on the upper support in a penetrating manner. The invention provides an anti-earthquake support system provided with steel wire ropes and used for a rectangular air pipe. The anti-earthquake support system provided with the steel wire ropes and used for the rectangular air pipe is more stable in support, and capableof uniformly limiting an allowable swing amplitude, an elastic extrusion state and the like of the rectangular air pipe; and therefore, a plurality of anti-earthquake supports are capable of uniformlydispersing an action force during an earthquake, and the anti-earthquake support system is worthy of popularization.

Description

Technical field [0001] The invention relates to the technical field of air duct anti-seismic devices, in particular to a rectangular air duct steel wire rope seismic support system. Background technique [0002] In the prior art, a flexible anti-seismic support system for air duct equipment with the application number "201710464652.4" includes: an upper support rod and a lower support rod arranged at intervals, and fixed columns whose ends are respectively connected to the upper support rod and the lower support rod , And the flexible anti-seismic system arranged on both sides of the fixed column, the flexible anti-seismic system, including steel wire rope connector one, steel wire rope connector two, support rope, steel wire rope connector three, compression rope, locking column and compression rope suspension mechanism , The compression rope suspension mechanism is connected to the middle of the compression rope. The compression rope suspension mechanism includes a slider, a sp...

Problems solved by technology

[0003] However, there are still obvious defects in its use: 1. The above-mentioned device is mainly suitable for the anti-seismic of circular air ducts, but not for the anti-seismic of rectangular air ducts. This is because rectangular air ducts usually have edges and corners. When placed on the support rope, there are only contact points at the edges and corners, and the contact area is small, which will lead to unstable placement, and the edges and corners are easy to cut the support rope, and the local pressure is too large, which may easily cause the support rope to break; 2. The air duct in the above device The allowable shaking range is too large, and the shock absorption effect is weak. When a slight vibration occurs, the air duct will easily drive the related structure to shake to a large extent, making its connecting structure very easy to be pulled and broken.
