Bridge shock absorption and falling prevention device

Abstract

The invention discloses a bridge shock absorption and falling prevention device, and belongs to the field of bridge shock absorption. The bridge shock absorption and falling prevention device body includes two-way hinged supports 1, protective sleeves 5, a pair of piston rods 6, oil cylinders 7 and damp fluids 8, wherein the pair of piston rods are arranged in the bridge shock absorption and falling prevention device, the oil cylinders are filled with the damp fluids, and the hinged supports 1 are connected to panels at the ends of a bridge. Under the action of an earthquake or other external force, the displacement of the bridge can drive the piston rods 6 to move in the damp fluids 8, so that a role of reducing the effect of external forces can be played and it is ensured that the two-way hinge supports at both ends can play a role under the action of external forces in most directions, and meanwhile when the tension reaches the limit, the bridge is locked, thus falling of the bridge is effectively prevented. According to the bridge shock absorption and falling prevention device, the energy brought by the external force is consumed, the large displacement of the bridge is limited, the bridge can be locked to be prevented from falling when the bridge moves beyond the displacement, the fatigue property is good, installation and disassembly are convenient, and the application range is wide.

Description

technical field [0001] The invention relates to the field of shock absorption of civil engineering bridges, in particular to a shock absorption and fall prevention device. Background technique [0002] Earthquake is a natural disaster that poses a great threat to the safety of engineering structures. [0003] If the bridge displaces more than expected due to earthquakes, floods, impacts, etc., the bridge may fall, which will cause huge casualties, economic losses, and also affect the follow-up rescue work. [0004] With the economic development of our country and the innovation of various industries, the anti-seismic technology of bridges has developed rapidly in recent years. From the past, relying solely on damaged structural components to resist adverse forces such as earthquakes, it has developed to the use of energy-consuming damping technology to reduce external forces. consume energy. [0005] The existing anti-seismic devices of bridges in our country are mainly an...
