The invention relates to the technical field of bridge prefabricated part hoisting, and discloses a bridge prefabricated part hoisting device which comprises a main winch, the main winch is fixedly connected to the middle of the bottom end of the interior of a cross beam, auxiliary winches are fixedly connected to the left side and the right side of the bottom end of the interior of the cross beam, and a mounting plate is arranged at the bottom of the cross beam; a plurality of mooring ropes are arranged on the left side and the right side of the top of the mounting plate, the main winch and the auxiliary winch are fixedly connected with the mounting plate through the mooring ropes, and a first gear is rotationally connected to the inner side of the mounting plate. The main winch is started, the height of the mounting plate is adjusted through the cable to hoist a workpiece, the auxiliary winches on the two sides are synchronously started to assist in transmission of the cable to reduce starting slippage, and if the center of the workpiece deviates to incline the mounting plate, the second gear and the telescopic plate are rotated to push the balancing weight to the inclined reverse side, so that the mounting plate is aligned to keep stable hoisting.

    本发明涉及桥梁预制构件吊装技术领域,公开了一种桥梁预制件起吊装置,包括主卷扬机,所述主卷扬机固定连接在所述横梁的内部底端中部,所述横梁的内部底端左右侧均固定连接有副卷扬机,所述横梁的底部设置有安装板,所述安装板的顶部左右侧设置有多个缆绳,所述主卷扬机与所述副卷扬机之间均通过所述缆绳与所述安装板固定连接,所述安装板的内侧转动连接有齿轮一。通过启动主卷扬机,借缆绳调整安装板高低以起吊工件,同步启动两侧副卷扬机辅助传动缆绳减少启动滑移,若工件中心偏移使安装板倾斜,之后转动齿轮二及伸缩板转动,推动配重块至倾斜反侧,使安装板回正保持起吊稳定。
