The invention provides an auxiliary hoisting device for bridge construction. The device comprises a connecting frame and a hoisting frame; the interior of a base is of a hollow structure, and a planebearing is arranged inside the base; the bottom of a main frame body is connected into the base, a winch is fixedly arranged on the outer side of the main frame body, and the winch is connected with an external control circuit; a lead screw is rotationally connected to the top of the main frame body, and one end of the lead screw is connected with a transmission belt; and an adjusting motor is arranged at the top of the main frame body, and the adjusting motor is connected with the external control circuit. According to the device, according to the requirements of placing angles of a hoisted object, a transmission motor drives a worm inside the connecting frame to rotate, and the worm drives a worm wheel to rotate, so that the worm wheel drives the hoisting frame to rotate, the hoisting frame drives the hoisted object to rotate, and then the requirements of different placing angles of the hoisted object are well met; and after the hoisting frame completes rotating adjusting, through the self-locking characteristic of the worm and the worm wheel, the hoisting frame is fixed, and the stability of the hoisting frame in use is guaranteed.

    本发明提供一种桥梁施工用辅助吊装装置,包括连接架和吊装架;所述底座内部为中空状结构,平面轴承安装于底座内部;所述主架体底部连接于底座内,且主架体外侧固定安装有一处卷扬机,卷扬机与外部控制线路相连;所述丝杆转动连接于主架体顶部,丝杆一端与传动带相连;所述调节电机安装在主架体顶部,调节电机与外部控制线路相连;本发明可根据吊装物品放置角度所需,通过传动电机带动连接架内部蜗杆转动,蜗杆进一步带动蜗轮转动,从而通过蜗轮带动吊装架转动,吊装架带动吊装物品转动,更好的满足于吊装物品不同角度放置需求,并在吊装架转动调节完毕后,通过蜗杆与蜗轮自锁特性,对吊装架进行固定,保障吊装架使用时的稳定性。
