Arrangement construction method of hoisting device of steel truss girder
The invention relates to an arrangement construction method of a hoisting device of a steel truss girder, and belongs to the field of hoisting of steel truss girders. The method comprises the steps that a transport ship loads a steel truss to be close to a branch trestle, and the transport ship leans against a ship berthing pile on the side of the branch trestle through anchor chain mooring of the transport ship; the two floating cranes fix the limiting rod pieces between the cable columns through shackles; the two floating cranes are hinged to be close to the transport ship through floating crane anchor chains and form a splayed position towards the transport ship, and lifting hooks on the floating cranes and the gravity center of a steel truss girder are located on the same vertical plane; the lifting hook is connected with the steel truss girder lifting lug, and the floating crane lifts the steel truss girder to the top of the bow of the transport ship; after the transport ship is driven away, the floating crane continues to hoist the steel truss girder to be above the designed elevation; and the steel truss girder is located above the pier-side bracket, the lifting hook descends, and the steel truss girder is placed on a slide way beam at the top of the pier-side bracket. And the width of the front part of the floating crane is reduced, the hoisting positions are increased, and the hoisting efficiency is improved.
本申请涉及一种钢桁梁的吊装装置的布置施工方法，属于钢桁梁的吊装领域。本方法包括运输船装载钢桁梁靠近支栈桥，通过运输船锚链绞锚，使运输船靠在所述支栈桥边靠船桩上；两台浮吊通过卸扣将限位杆件固定于缆绳柱之间；两台所述浮吊通过浮吊锚链铰锚靠近所述运输船，朝向所述运输船形成八字形站位，并使所述浮吊上的吊钩与钢桁梁重心位于同一竖直面上；所述吊钩与所述钢桁梁吊耳连接，所述浮吊起吊钢桁梁至所述运输船船头顶部；所述运输船驶离后，所述浮吊继续起吊所述钢桁梁至设计高程以上；钢桁梁位于墩旁托架上方，所述吊钩下降，将所述钢桁梁放置在墩旁托架顶部滑道梁上。浮吊前部的宽度会变小，吊装位置增多，利于吊装效率的提高。
