A Rectangular Air Duct Steel Wire Rope Anti-seismic Support System

Abstract

The invention discloses a rectangular air duct steel wire rope anti-seismic support system, which comprises a lower support on which a rectangular air duct is placed, and L-shaped limiting plates are arranged on both sides of the rectangular air duct; A rubber push plate is arranged below, and a damping spring is connected between the rubber push plate and the upper bracket; the upper bracket is symmetrically provided with fixed blocks on both sides of the rubber push plate, and an L-shaped fixed block is arranged in the fixed block. Piston cavity, the side of the second piston plate away from the L-shaped piston cavity is fixedly provided with a second clamping rod; the outer side of the connector is fixedly provided with a ring plate, and the ring plate is provided with a plurality of threaded holes ; The upper bracket is symmetrically threaded with steel wire ropes. The invention provides a rectangular air duct steel wire rope anti-seismic support system with more stable support, which can uniformly limit the allowable shaking range and elastic extrusion state of the rectangular air duct, so multiple anti-seismic supports can evenly disperse the force during an earthquake, which is very It is worth promoting.

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 anti-seismic support system. Background technique [0002] In the prior art, the application number is "201710464652.4", a flexible anti-seismic support system for air duct equipment, including: an upper support rod and a lower support rod arranged at intervals, and a fixing column whose two 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 includes the first wire rope connector, the second wire rope connector, the support rope, the third wire rope connector, the compression rope, the locking column and the compression rope suspension mechanism , the middle part of the compression rope is connected with a compression rope suspension mechanism, the compression rope suspensio...

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.
