The invention relates to the field of pipe culvert hoisting, in particular to a reinforced concrete circular pipe culvert hoisting device which comprises a hoisting rope, a hoisting tool and a distance adjusting rod. The number of the lifting ropes is two, the number of the lifting appliances is two, and each lifting rope is connected with one lifting appliance. One end of the lifting rope is connected to the lifting appliance, and the other end is connected with lifting equipment; the two ends of the distance adjusting rod are in sliding connection with the lifting ropes respectively; the distance adjusting rod is used for adjusting the lifting rope in a tensioned state from a linear posture to a broken line posture: in the linear posture, the lifting rope is tensioned by the lifting appliance and the lifting equipment and is linear; and in the broken line posture, the lifting ropes are tensioned by the lifting appliance, the lifting equipment and the distance adjusting rod and are in a broken line shape, and the two lifting ropes are bent to form an included angle towards the sides close to each other. The round pipe culvert has the effect of reducing damage to the ends of the round pipe culvert.

    本申请涉及一种钢筋混凝土圆管涵吊装装置,涉及管涵吊装的领域,其包括吊绳、吊具和调距杆;所述吊绳和所述吊具各设有两个,每一所述吊绳各连接有一个所述吊具;所述吊绳一端连接于吊具,另一端用于连接起吊设备;所述调距杆两端各与一个所述吊绳滑动连接;所述调距杆用于将张紧状态的所述吊绳由直线姿态调整为折线姿态:直线姿态下,所述吊绳被所述吊具和起吊设备张紧,呈直线型;折线姿态下,所述吊绳被所述吊具、起吊设备和调距杆张紧,呈折线形,且两个所述吊绳弯折形成夹角朝向相互靠近的一侧。本申请具有减少圆管涵端部损坏的效果。
