The invention relates to the technical field of cranes, and discloses an adjustable crane boom which comprises a stand column, a rope fixing assembly and a buckle assembly. A rotating shaft is fixedlyinstalled on the inner wall of the stand column, a cable reel is fixedly installed on the left side of the stand column, and a steel cable is movably connected to the inner wall of the cable reel. After a user adjusts a first arm frame and a second arm frame to unfold a whole crane, a steel cable is put down and firmly hangs an object to be hoisted, and the first arm frame and the second arm frame are continuously adjusted to hoist the object, the steel cable is finally extruded into a groove in the bottom of the second arm frame along with upward movement of a pay-off wheel, meanwhile, a sensor is touched to start a motor to start reverse operation, at the moment, the steel cable and a hoisting rod can be preliminarily clamped, and the situation that the object is driven by inertia generated during object moving to swing is prevented. Then, through the buckle assembly, a fixed shell begins to move upwards along a hanging rod, and finally, the whole fixed shell is fixed between the second arm frame and the hoisting rod.

    本发明涉及起重机技术领域,且公开了一种可调节的起重机臂架,包括立柱、固绳组件与卡扣组件,所述立柱的内壁固定安装有转轴,所述立柱的左侧固定安装有线缆盘,所述线缆盘的内壁活动连接有钢缆,当使用者通过调节第一臂架与第二臂架将整个起重机展开,并将钢缆放下挂牢待吊物品之后再继续调节第一臂架与第二臂架将物品吊起时随着放线轮上移最终将钢缆挤压到第二臂架底部凹槽并同时触碰感应器启动电机开始反向运转,此时可以初步将钢缆与吊杆之间初步夹紧,防止物品移动时产生的惯性带动物品晃动,之后再通过卡扣组件,使固定壳开始顺着吊杆上移,最终使整个固定壳在第二臂架与吊杆之间固定。
