The invention discloses hoisting equipment for bridge construction. The hoisting equipment structurally comprises fixed plates, a rotating sliding rods, switching sliding blocks, movable shafts, sliding grooves, hooks and adjusting rods, wherein the upper surface of each fixed plate is in threaded connection with the corresponding hooks, the sliding grooves are formed in the fixed plates, the rotating sliding rods are movably connected in the sliding grooves, and the rotating sliding rods are movably connected with the switching sliding blocks through the movable shafts; the two ends of the adjusting rod are fixedly connected to the inner sides of the transfer sliding blocks, each transfer sliding block is provided with a fastening rod, a clamping block and a transfer opening, each fastening rod is connected to the interior of the corresponding clamping block in a nested manner, and the surface of the outer end of each clamping block is fixedly connected with the corresponding transfer opening; and the movable shafts are adjusted, the rotating sliding rods are swung, and by means of the fixing blocks in the fastening rods, steel pipes of different sizes are automatically adjusted and fixed, the situation that the steel pipes slide and fall off in the moving process to threaten the life safety of personnel is prevented, and the operation difficulty of the hoisting equipment is reduced.

本发明公开一种桥梁施工用吊装设备，其结构设有固定板、转动滑杆、转接滑块、活动轴、滑槽、挂钩、调节杆，固定板上方表面螺纹连接着挂钩，固定板内部设有滑槽，转动滑杆活动连接在滑槽内部，转动滑杆通过活动轴与转接滑块活动连接，调节杆两端固定连接在转接滑块内侧，转接滑块设有紧固杆、卡块、转接口，紧固杆嵌套连接在卡块内部，卡块外端表面固定连接着转接口，本发明通过紧固杆在转接滑块内部进行移动沿着钢管外壁进行调整固定，对活动轴进行调整与对转动滑杆进行摆动，借助紧固杆内部的固定块对不同尺寸的钢管进行自动调整固定，防止钢管在移动过程中发生滑动掉落对人员的生命安全造成威胁，减小对吊装设备的操作难度。
