Gantry crane for road and bridge construction
The invention relates to the technical field of gantry cranes for bridge construction, and particularly relates to a gantry crane for road and bridge construction. The gantry crane comprises a supporting plate and two fixing plates, wherein the two fixing plates are symmetrically arranged; the top ends of the two fixing plates are fixedly connected with two supporting columns; a connecting rod isfixedly connected between the two supporting columns; first sliding grooves are formed in the top ends of the supporting columns; square columns are slidably connected to the interiors of the first sliding grooves; threaded holes are formed in the bottom ends of the square columns; first screw rods are arranged in the threaded holes in a threaded mode; square grooves are formed in the positions, below the first sliding grooves, of the interiors of the supporting columns; the bottom ends of the first screw rods extend into the square grooves and are fixedly connected with first bevel gears; rotating shafts are arranged on the outer sides of the supporting columns; and the ends, extending into the square grooves, of the rotating shafts are fixedly connected with second bevel gears. The gantry crane is simple in structure and convenient to disassemble and transport, the height of the gantry crane can be adjusted, meanwhile, the angle of the gantry crane can be conveniently adjusted, the practicability of the gantry crane in use is improved, and the use limitation of the gantry crane is reduced.
本发明涉及桥梁施工用龙门吊架技术领域，具体为一种道路桥梁施工用龙门吊架，包括支撑板和两个固定板，两个所述固定板对称设置，两个固定板的顶端均固定连接有两个支柱，两个支柱之间固定连接有连接杆，支柱的顶端设置有第一滑槽，第一滑槽的内部滑动连接有方柱，方柱的底端设置有螺纹孔，螺纹孔内螺装有第一螺杆，支柱的内部在第一滑槽的下方设置有方槽，所述第一螺杆的底端延伸至方槽的内部固定连接有第一锥形齿轮，支柱的外侧设置有转轴，转轴延伸至方槽内部的一端固定连接有第二锥形齿轮；其结构简单，便于拆卸运输，能对其高度进行调节，同时便于对其角度进行调节，提高了其使用的实用性，降低其使用局限性。
