Cable-crossing crane of suspension bridge as well as application and using method of cable-crossing crane
The invention belongs to the technical field of bridge engineering. The invention relates to a cable-crossing crane of a suspension bridge as well as application and a using method of the cable-crossing crane. The cable-crossing crane comprises hoisting units, a hydraulic control unit and a cross beam; the number of the hoisting units is three; the three sets of hoisting units are sequentially connected through the cross beam from left to right; the hydraulic control unit is connected with the middle hoisting unit. According to a three-main-cable suspension bridge in the prior art, during thehoisting construction of a stiffening beam, if a two-supporting-point hoisting mode of a conventional cable-crossing crane is adopted, the requirement on the hoisting capacity of a hoisting unit is very high, and the stiffening beam is largely deformed in the hoisting process. With the cable-crossing crane of the suspension bridge as well the application and using method of the cable-crossing crane adopted, the above problem in the prior art can be solved. According to the cable-crossing crane of the suspension bridge as well the application and using method of the cable-crossing crane, one hoisting unit is arranged at each of the left position, the middle position and the right position, the hoisting unit in the middle shares loads of the hoisting units on the two sides, and therefore, the deformation of the stiffening beam is within a controllable range. The cable-crossing crane has high practical significance and research value.
本发明属于桥梁工程技术领域，具体涉及一种悬索桥的跨缆吊机及其应用和使用方法，包括吊装单元、液压控制单元、横梁，吊装单元的数量为3套，3套吊装单元自左向右依次通过横梁连接，液压控制单元连接中间的吊装单元，解决了现有技术中三主缆悬索桥，在进行加劲梁吊装施工时，若采用常规跨缆吊机的两支点起吊形式，对吊装单元的起吊能力要求非常高，且起吊过程中加劲梁的变形比较大的问题，本发明在左、中、右三个位置各设置1套吊装单元，中间的吊装单元分担了两边吊装单元的荷载，且加劲梁的变形也在可控范围内，该结构具有较高的实际意义和研究价值。
