Trackless maintenance car for simply supported girder bridge of high-speed rail
The invention discloses a trackless maintenance car for a simply supported girder bridge of a high-speed rail, and relates to the technical field of maintenance cars for simply supported girder bridges of high-speed rails, the trackless maintenance car comprises a concrete beam, both sides of the concrete beam are provided with walking pendants, and the bottoms of the walking pendants are provided with trackless walking system assemblys.The trackless maintenance car has the beneficial effects that conventional rail arrangement is effectively simplified; the load of the track weight on the beam body is greatly reduced, meanwhile, aiming at the continuous beam body with dense holes, the maintenance car can be rotated by a certain angle or folded, passes through the bridge pier and then is unfolded, so that one maintenance car does not need to be arranged in each bridge opening, the configuration number of the maintenance cars is effectively reduced, namely, the budget cost is reduced, and the maintenance efficiency is improved. Meanwhile, under the action of the lifting system, the horizontal frame can always keep a certain height from the bottom of the variable cross-section beam, so that the operation risk caused by the fact that a fixed frame needs to be overhauled by a worker at a high cross-section position is avoided, and the safety of the worker or the property safety is effectively guaranteed.
本发明公开了一种高铁简支梁桥无轨式检修车，涉及高铁简支梁桥检修车技术领域，包括混凝土梁，混凝土梁的两侧均设置有走形挂件，走形挂件的底部安装有无轨式走行系统组件，本发明的有益效果为：有效的简化了常规轨道布置，极大的降低了因轨道重量带给梁体的荷载，同时针对孔洞密集的连续梁体，可将检修车旋转一定的角度或折叠，通过桥墩以后再展开，这就不需要每个桥洞都设置一台检修车，有效降低了检修车配置数量，即降低了预算成本，同时在升降系统的作用下，水平框架可以始终与变截面梁底保持一定高度，避免了固定式的框架，在高截面位置，人员还需要搭很高的梯子才能检修，而带来的操作风险，有效保障了，人员的安全或财产安全。
