The invention belongs to the technical field of fixing frames for transportation, particularly relates to a fixing frame for bridge steel structure transportation, and aims to solve problems that a protective coating on a steel plate is easily abraded, the service life of the steel plate is shortened, and steel plates with different sizes are inconvenient to fix during transportation of an existing fixing frame for bridge steel structure transportation. According to the scheme, the frame comprises a movable base, two symmetrical supporting plates are fixed to the top of the movable base, a fixed box is connected between the two supporting plates in a sliding mode, and guide blocks are fixed to the two side walls of the fixed box. A one-way screw rod is rotated through an adjusting mechanism and a first hand wheel, the one-way screw rod is in threaded connection with the lifting plate of the one-way screw rod, then the lifting plate can move upwards or downwards on a sliding groove in the inner wall of the fixed box through the sliding block, and meanwhile a spline sleeve moves upwards or downwards on a spline shaft; and the distance between the lifting plate and the fixing plate can be conveniently adjusted according to steel plates with different sizes.
本发明属于运输用固定架技术领域,尤其是一种桥梁钢结构运输用固定架,针对现有的桥梁钢结构运输用固定架,在运输时,容易对钢板上的防护涂层造成磨损,降低钢板使用寿命,且不方便对不同大小尺寸的钢板进行固定的问题。现提出如下方案,其包括移动底座,所述移动底座的顶部固定有两个相对称的支撑板,两个支撑板之间滑动连接有固定箱,固定箱的两侧壁上均固定有导向块。本发明通过调节机构,并通过手轮一转动单向丝杆,由于单向丝杆与之升降板螺纹连接,继而使升降板能够通过滑块在固定箱内壁上的滑槽上进行上移或下移,且同时花键套在花键轴上上移或下移,便于针对不同尺寸的钢板对其升降板与之固定板之间的距离进行调节。
