The invention discloses a lifting appliance with a positioning function for laying municipal culvert pipes, and relates to the technical field of culvert pipe lifting. The technical problem that when an existing U-shaped lifting appliance is used for transporting a culvert pipe, the culvert pipe is likely to deviate and slide off, and workers are injured is solved. The invention provides a municipal culvert pipe laying lifting appliance with a positioning function, which comprises a support frame, the support frame is slidably connected with a sliding bracket, the sliding bracket is slidably connected with a sliding block and a fixed rod, a spring is fixedly connected between the fixed rod and the sliding bracket, the sliding block is rotatably connected with a power hydraulic cylinder, and the power hydraulic cylinder is rotatably connected with the sliding bracket. A power piston is connected into the power hydraulic cylinder in a sliding mode, the power piston is fixedly connected with a supporting rod, and the supporting rod is fixedly connected with a hanging ring. The position of the lifting ring of the supporting frame is changed when the culvert pipe is lifted to adapt to the positions of the gravity centers of different culvert pipes, and it is avoided that in the culvert pipe moving process, the culvert pipe deviates and slides off, and injuries are caused to workers below the culvert pipe.

    本发明公开了涉及涵管吊装技术领域的一种市政涵管铺设用具有定位功能的吊具。为解决现有U型吊具在运输涵管时容易使涵管偏移滑落,导致工作人员受伤的技术问题。本发明提供一种市政涵管铺设用具有定位功能的吊具,包括有支撑架,所述支撑架滑动连接有滑动支架,所述滑动支架滑动连接有滑块和固定杆,所述固定杆与所述滑动支架之间固接有弹簧,所述滑块转动连接有动力液压筒,所述动力液压筒内滑动连接有动力活塞,所述动力活塞固接有支撑杆,所述支撑杆固接有吊环。本发明通过改变吊装涵管时支撑架吊环的位置,来适应不同涵管重心的位置,避免在移动涵管的过程中,涵管发生偏移滑落,对下方的工作人员造成伤害。
