Suspender counterweight system in bridge girder assembly process

LI SHIYA / WANG XU

The invention relates to the field of suspension bridges, and particularly discloses a suspender counterweight system in the bridge girder assembly process, which comprises a steel suspender, a lower hinged support, a counterweight unit and a steel girder, the lower hinged support is fixedly arranged below the steel suspender; each counterweight unit comprises two L-shaped counterweight bases, a connecting steel cable, a sling and a counterweight block, each counterweight base comprises a horizontal part and a vertical part, the slings are fixedly arranged at the bottoms of the vertical parts of the counterweight bases, the counterweight blocks are fixedly arranged on the slings, the two counterweight bases are arranged on the two opposite lower hinged supports respectively, and the connecting steel cables are arranged on the lower hinged supports. A plurality of connecting rings are arranged on the opposite sides of the horizontal parts of the two counterweight bases, and the two sides of the connecting steel cable are arranged on the connecting rings correspondingly; the steel main beam comprises a beam body and a connecting hinged support, the connecting hinged support is arranged on the beam body, and a vertical groove is formed in the upper end of the connecting hinged support. The invention aims to solve the technical problem of how to realize smooth transition and replacement of the main beam and the substitute.

本发明涉及悬索桥领域，具体公开了桥梁主梁装配过程中吊杆配重系统，钢吊杆、下部铰支座、配重单元和钢主梁；下部铰支座固定设置在钢吊杆的下方；配重单元包括两块L字形状的配重底座、连接钢缆、吊索和配重块，配重底座包括水平的水平部和竖直的竖直部，吊索固定设置在配重底座的竖直部底部，配重块固定设置在吊索上，两块配重底座分别设置在相对的两个下部铰支座上，两块配重底座水平部相对的一侧均设置有若干连接环，连接钢缆的两侧分别设置在连接环上；钢主梁包括梁体和连接铰支座，连接铰支座设置在梁体上，连接铰支座的上端设置有竖向凹槽。本发明的目的在于解决如何使主梁与代替物平稳过渡替换的技术问题。
