Long-distance steel box girder dragging system crossing existing line
The invention relates to the field of bridge construction, and provides a long-distance steel box girder dragging system crossing an existing line. Dragging construction equipment comprises a supporting device, a dragging device and a deviation rectifying device. The supporting device comprises a rolling device; the dragging device comprises a first steel wire rope fixed pulley assembly, a movablepulley assembly and a first winding device; the deviation rectifying device comprises an installation support and a second winding device. The installation support comprises two support bodies, fixedpulleys are arranged on the support bodies, a second steel wire rope is wound on the second winding device, and a connecting piece used for being connected with the steel box girder is arranged at the end of the second steel wire rope. The steel box girder is supported by the rolling device; sliding friction is converted into rolling friction, the friction force of the contact position is reduced, so that the power of the dragging device is reduced and the service life of each component is prolonged; the position of the steel box girder is adjusted through the deviation rectifying device, thesteel box girder moves in the designed direction, so that the matching difficulty between the steel box girder and the supporting device is reduced, and construction is smoothly conducted.
本发明涉及桥梁施工领域，提供了一种跨越既有线路长距离钢箱梁拖拉系统。该拖拉施工设备包括支撑装置、拖拉装置和纠偏装置，支撑装置包括滚动装置；拖拉装置包括第一钢丝绳定滑轮组件、动滑轮组件和第一卷扬装置；纠偏装置包括安装支架和第二卷扬装置，安装支架包括两个支架本体，支架本体上设有定滑轮，第二卷扬装置上缠绕有第二钢丝绳，第二钢丝绳的端部设有用于与钢箱梁连接的连接件。本申请通过滚动装置支撑钢箱梁，将滑动摩擦转换成滚动摩擦，减少接触位置的摩擦力，进而减少拖拉装置的动力，增加各个部件的使用寿命，并通过纠偏装置调整钢箱梁位置，使得钢箱梁按照设计方向移动，降低钢箱梁和支撑装置之间的配合难度，使得施工顺利进行。
