Steel structure bridge box girder angle adjusting device facilitating clamping length adjustment
The invention relates to the field of bridge box girders, in particular to a steel structure bridge box girder angle adjusting device capable of conveniently adjusting clamping length, which comprises a portal frame, two groups of hydraulic winding mechanisms are mounted on the portal frame, the hydraulic winding mechanisms are connected with clamping blocks below through hydraulic steel ropes, the clamping blocks are clamped on two sides of a box girder, and the hydraulic steel ropes are connected with the clamping blocks through hydraulic steel ropes. A supporting rope is arranged between the bottoms of the clamping blocks on the two sides. The hydraulic steel ropes on the two sides are sleeved with wire fixing devices, through grooves are formed in the wire fixing devices, elastic pressing pieces are installed in the through grooves, friction blocks are arranged in the middles of the elastic pressing pieces, and after the friction blocks are extruded by external force, the elastic pressing pieces deform to drive the friction blocks to move towards the inner sides to be in friction extrusion locking with the hydraulic steel ropes. According to the box girder butt-joint installation device, the box girder can be stably clamped and installed through the hydraulic suction cups, the clamping blocks and the clamping block hydraulic rods, the box girder is stably hoisted in cooperation with the hydraulic steel rope, angle adjustment can be conducted through the wire fixing devices on the hydraulic steel rope, and therefore the box girder can be rapidly installed in a butt-joint mode.
本发明涉及桥梁箱梁领域，尤其涉及便于调节装夹长度的便于调节装夹长度的钢结构桥梁箱梁角度调节装置，包括龙门架，所述龙门架上安装有两组液压收卷机构，液压收卷机构通过液压钢绳与下方的夹块连接，夹块夹设在箱梁的两侧，且两侧夹块的底部之间设置有托绳；两侧所述液压钢绳上均套设安装有固线器，固线器上设置有通槽，通槽内安装有弹性压片，弹性压片的中部设置有摩擦块，当摩擦块受外力挤压后，弹性压片形变驱使摩擦块往内侧移动与液压钢绳摩擦挤压锁紧。本发明中，通过液压吸盘、夹块、夹块液压杆可稳定装夹安装箱梁，配合液压钢绳将箱梁稳定吊起，且通过液压钢绳上的固线器可进行角度调节，从而可将箱梁快速对接安装。
