Movable support device for variable cross-section box girder bridge detection
The invention discloses a movable support device for detecting a variable cross-section box girder bridge, which comprises guardrails mounted on two sides of a bridge deck pavement, and the guardrails on two sides and F-shaped supports arranged at equal intervals in the length direction of the guardrails form guardrail anchoring combinations. The bottom of the guardrail anchoring combination is connected with a longitudinal rail laid in the length direction of the bridge, a transverse detection channel is installed on the lower portion of the bridge, maintenance supports are installed at the two ends of the transverse detection channel respectively, and crown blocks capable of moving on the longitudinal rail are installed at the tops of the maintenance supports. The device has the advantages of being easy to anchor and install, capable of effectively reducing the influence on the existing traffic operation condition under the bridge in construction engineering, convenient for maintainers to smoothly arrive at the bottom plate of the variable cross-section prestressed concrete beam, capable of smoothly achieving detection and maintenance on the lower portion of the large-span variable cross-section continuous box beam, safe, reliable and high in practicability. And the working effect is greatly improved.
本发明公开了一种用于变截面箱梁桥梁检测的移动支架装置，其构成部件包括安装在桥面铺装两侧的护栏，两侧所述的护栏均与其长度方向等间隔排布的F型支撑构成护栏锚固组合，所述护栏锚固组合的底部连接沿所述桥梁长度方向铺设的纵向轨道，桥梁的下部安装横向检测通道，横向检修通道的两端分别安装检修支架，检修支架的顶部安装可在所述的纵向轨道上移动的天车。本发明的优点在于：易于锚固和安装，可有效减少施工工程中对桥下既有交通运行状况的影响，方便检修人员顺利抵达变截面预应力混凝土梁的底板处，顺利实现对大跨径变截面连续箱梁下方的检测、检修，不仅安全可靠，而且还使工作成效得到大幅度提高。
