Movable portal frame used on road
The movable portal frame used on the road comprises a cross rod, stand columns are rotatably connected to the two ends of the cross rod, supporting columns are connected to the interiors of the stand columns in a sleeved mode, fixing mechanisms for supporting the supporting columns are arranged at the bottoms of the supporting columns, and driving mechanisms for controlling the heights of the stand columns are embedded in the outer end faces of the supporting columns. Compared with a portal frame, the device is more convenient to adjust, the problem of corrosion of an adjusting assembly is avoided, meanwhile, the device is convenient to disassemble and use for the second time, and the requirement for the road surface is low.
本发明公开一种用于道路上的可移动龙门架，包括横杆，所述横杆的两端转动连接有立柱，所述立柱的内部套接连接有支撑柱，所述支撑柱的底部设有对支撑柱进行支撑的固定机构，所述支撑柱的外端面嵌设有控制立柱高度的驱动机构，所述驱动机构的内部转动卡接有控制驱动机构转动的驱动转杆，该装置相较于龙门架调节更加便捷，其避免了调节组件锈蚀的问题，同时便于装置的拆卸和二次使用，对路面要求较低。
