The crane comprises a stand column, a suspension arm, a main hook and an auxiliary hook, the suspension arm is arranged on one side of the outer wall of a main shaft, a winch is arranged on one side of the bottom of the suspension arm, a steel wire rope is wound on the winch, a pulley block is arranged at the bottom of the steel wire rope, and supports are arranged on the two sides of the outer wall of the middle of the pulley block; when goods are hoisted, hoisting is conducted through the main hook, auxiliary hoisting is conducted on the two sides of the goods through the auxiliary hook, in the hoisting walking process, through cooperation of the spring sleeve rod and the auxiliary hook, shaking generated by the goods is buffered, impact on the main hook is reduced, and the goods can be hoisted through the main hook and the auxiliary hook. Meanwhile, when the main hook is impacted, the spherical pad and the rubber pad between the coupling shaft and the supporting plate are used for buffering, so that the impact on the main hook is further reduced, the stress concentration at the hooking part of the main hook is reduced, and the service life and the use safety of the main hook are ensured.
本发明公开了一种带有挂钩应力抵消的起重机,包括:立柱、吊臂、主钩和副钩,所述主轴外壁一侧设有吊臂,所述吊臂底部一侧设有卷扬机,所述卷扬机上缠绕有钢丝绳,所述钢丝绳底部设有滑轮组,所述滑轮组中部外壁两侧设有支架,所述支架底部之间设有支撑板,所述支撑板中央设有联结轴,本发明在吊运货物时,通过主钩进行吊运,通过副钩对货物两侧进行辅助吊运,在吊运行走过程中,通过弹簧套杆与副钩的配合,缓冲货物产生的晃动,减少对主钩的冲击,同时在主钩受到冲击时,通过联结轴与支撑板之间的球形垫以及橡胶垫进行缓冲,进一步减少主钩受到的冲击,减少主钩挂接处的应力集中,保证主钩的使用寿命与使用安全。
