Truss type wheel-rail bridge deck crane and large-span steel box bridge construction method
The invention relates to the technical field of building equipment, and discloses a truss type wheel-rail bridge deck crane and a large-span steel box bridge construction method. A first truss beam, a second truss beam, a first supporting assembly and a second supporting assembly are all of a truss structure, the bending strength and the shearing resistance of the truss structure are high, and the bearing capacity of the first truss beam and the second truss beam is improved. Therefore, the hoisting stability of the bridge deck crane can be guaranteed without arranging an inclined supporting rod, and the working space during hoisting operation is effectively increased. In addition, a walking assembly is rotationally connected with the first supporting assembly and the second supporting assembly, and the included angle between the walking assembly and the first supporting assembly and the included angle between the walking assembly and the second supporting assembly can be adaptively changed, so that the walking assembly is in rolling fit with a walking rail all the time, different slope changes of a bridge deck, bending and turning of the bridge deck and the like are adapted, a curved bridge deck and a variable-slope bridge deck can be constructed, the walking efficiency of the truss type wheel-rail bridge deck crane is high, and the construction convenience and the construction efficiency are improved.
本发明涉及建筑设备技术领域，公开一种桁架式轮轨桥面吊及大跨度钢箱桥施工方法，第一桁架梁、第二桁架梁、第一支撑组件和第二支撑组件均为桁架结构，桁架结构的抗弯强度和抗剪能力强，提高了第一桁架梁和第二桁架梁的承载能力。因此无需设置斜撑杆即可保证桥面吊的吊装稳定性，有效增加吊装作业时的工作空间。此外，走行组件与第一支撑组件和第二支撑组件均为转动连接，走行组件与第一支撑组件和第二支撑组件之间的夹角可以适应性改变，以使走行组件与走行轨道始终滚动配合，从而适应桥面的不同坡度变化以及桥面的弯曲转弯等，可对曲线桥面和变坡度桥面进行施工，桁架式轮轨桥面吊的行走效率高，提高了施工便利性和施工效率。
