Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] see figure 1 , figure 2 , the present embodiment includes utilizing the box-type steel box girder 17 on the bridge structure, the bottom of the steel box girder 17 is processed with a square cavity 18, and the square cavity 18 includes a top plate and side plates around; it also includes a square Hanging blue 19, hanging blue 19 comprises hanging blue bottom plate 5 and the surrounding side wall 8 that is fixedly connected on it, hangs blue bottom plate 5 and has some water holes 6, is hinged with cover plate 7 on the water hole 6, not During operation, the cover plate 7 is in a closed state by the torsion spring (not shown in the figure), and the pre-tightening force of the torsion spring is small, so that the water flow under the cover plate 7 can easily wash away the cover plate 7; see also Figure 4, the four corners of the upper...

Abstract

The invention discloses a self-opening velocity type hydraulic energy absorption and consumption device. The self-opening velocity type hydraulic energy absorption and consumption device mainly comprises a steel box girder and a hanging basket, wherein the hanging basket is arranged in a square concave hole at the bottom of the steel box girder; the hanging basket comprises a hanging basket bottom plate and peripheral side walls; the hanging basket bottom plate is provided with a plurality of water through holes; a cover plate is hinged above the water through holes; one rope is connected with each of four corners at the upper part of the hanging basket; after the four ropes are bound together, the four ropes are connected with a hanging rope; the other end of the hanging rope is wound on one side of a rotary barrel; the rotary barrel is fixedly arranged on a top plate of the steel box girder; a pressing device and a friction sheet are mounted above the rotary barrel; a horizontal supporting plate is arranged at each of four corners of the bottom of the square concave hole; a vertical baffle is arranged on each horizontal supporting plate; the vertical baffles are connected with a side plate at the bottom of the square concave hole through limiting springs; and the four corners of the hanging basket bottom plate are supported on the four horizontal supporting plates at the bottom of the square concave hole through round balls. An energy consumption device can be automatically opened when a bridge starts to vibrate, and the vibration of the bridge is inhibited through hydraulic energy consumption.

Description

technical field [0001] The invention belongs to the technical field of structural dampers for large-span suspension bridges, and in particular relates to a self-opening speed type hydraulic energy absorber. Background technique [0002] Long-span suspension bridges can cross large rivers and can avoid the construction of deep-water foundations and are widely used. However, due to its large span and small damping of the main girder and main cable, it is easy to cause large torsion or combined bending-torsional vibration under the action of strong winds, resulting in bridge damage. The problem of its wind resistance stability is the main influence that limits the further increase of its span. factor. Increasing the damping of the suspension bridge can significantly improve its wind resistance stability, but the super-long-span suspension bridges are mostly located on the channel with heavy traffic. In order to ensure the safety of navigation, it is difficult to install perman...
