The invention discloses a large mechanical cargo boom, and belongs to a lifting device. The large mechanical cargo boom comprises a base and a rotary table, the middle part of the base is fixedly connected with a first motor, the left side of the upper surface of the rotary table is fixedly connected with a big arm, the top of the big arm is rotatably connected with a small arm, the left end partof the small arm is rotatably connected with a lifting head, and a pulley hook is arranged on the bottom side of the lifting head. A support is fixedly connected to the right side of the upper surfaceof the rotary table, a roller is rotatably connected to the top of the support, a driven bevel gear is fixedly connected to the front side of the roller, a second motor is arranged on the left side of the roller, and a driving bevel gear is fixedly connected to the right end of the second motor. Compared with the prior art, the large mechanical cargo boom has the beneficial effects that the largemechanical cargo boom is simple in structure and convenient to use, a hydraulic supporting rod is erected in the middle of the large arm to support the small arm to be lifted, a steel wire rope arranged on the pulley hook is connected with an idler wheel, the lifting weight range of the mechanical cargo boom is greatly widened, and the motors and a rotating shaft sleeve are arranged in the base and the rotary table to achieve lifting and transferring of weights in any direction.

    本发明公开了一种大型机械起重臂,属于一种起重装置,包括底座和旋转台,所述底座中部固定连接有一号电机,旋转台上表面左侧固定连接有大臂,大臂顶部转动连接有小臂,小臂左端部转动连接起重头,起重头底侧设有滑轮挂钩,所述旋转台上表面右侧固定连接有支架,支架顶部转动连接滚轮,滚轮前侧固定连接有从动锥齿轮,所述滚轮左侧设有二号电机,二号电机右端部固定连接有主动锥齿轮,与现有技术相比,本发明的有益效果是:本发明结构简单、使用方便,通过在大臂中部架设液压支杆支撑小臂抬起,滑轮挂钩上设有钢丝绳与滚轮连接,极大提升机械起重臂提升的重量范围,底座与旋转台中设有电机和转动轴套,可实现任意方向重物的起重转移工作。
