The invention relates to the technical field of cargo hoisting, and discloses a cargo crane which comprises a mounting base, a hoisting mechanism, a traction mechanism and a synchronous rotating mechanism, the hoisting mechanism comprises a first suspension plate arranged on the side, close to the ground, of the end of the mounting base, the first suspension plate is rotationally connected with a first transmission rod, a first winding roller is arranged in the middle of the first transmission rod, a suspension rope is wound around the first winding roller, and a first fixing head is arranged at the free end of the suspension rope; and the traction mechanism comprises extending beams arranged on the two sides of the mounting base, the extending beams are rotationally connected with driven driving rods, second winding rollers are arranged in the middles of the driven driving rods, and tensioning ropes are wound around the outer portions of the second winding rollers. By arranging the two sliding plates and the buffer spring capable of deforming, when the tension of the tensioning rope is too large, the second winding roller can rotate a few circles less than the first winding roller, and therefore the tensioning rope arranged in an inclined mode can be continuously kept in the traction state.
本发明涉及货物起吊技术领域,公开了一种货物起重机,包括安装基座、起吊机构、牵拉机构和同步旋转机构;起吊机构,包括设置于安装基座端部靠近地面一侧的第一悬挂板,第一悬挂板转动连接有第一传动杆,第一传动杆的中部设置有第一收卷辊,第一收卷辊外部缠绕有悬吊绳,悬吊绳的自由端设置有第一固定头;牵拉机构,包括设置于安装基座两侧的伸出梁,伸出梁转动连接有从动驱动杆,从动驱动杆的中部设置有第二收卷辊,第二收卷辊外部缠绕有涨紧绳。本发明通过设置两个滑动板以及可以形变的缓冲弹簧,使得涨紧绳的张力过大时第二收卷辊可以相较于第一收卷辊少转动几圈,从而使得倾斜设置的涨紧绳可以持续的保持牵拉的状态。
