The invention discloses a small crane grabbing device for loading coiled steel bars. The small crane grabbing device for loading the coiled steel bars comprises a lower circular plate, an upper circular plate, a driving mechanism, an extrusion mechanism and a force application feedback mechanism. The small crane grabbing device for loading the coiled steel bars is placed in the middle hollow position of the coiled steel bar through a crane, and then a motor is started, the motor drives a worm to rotate, the worm drives three double-end lead screws to rotate at the same time by being meshed with three worm wheels, the rotation of the double-end lead screws drives two nuts on the same double-end lead screw to move close to each other, and under the connection effect of connecting rods, extrusion plates can expand outwards and make extrusion contact with the inner side of the coiled steel bar; through the arrangement of inserting rods, the inserting rods are inserted into tight gaps in the extrusion process of the extrusion plates, so that stable supporting force is provided when reinforcing steel bars are hoisted, the situation that the reinforcing steel bars slide off is avoided, and the use safety of the small crane grabbing device for loading the coiled steel bars is improved; and according to the small crane grabbing device for loading the coiled steel bars, through cooperation of the driving mechanism and the extrusion mechanism, the coiled steel bars can be rapidly and stably grabbed.

    本发明公开了一种用于盘绕钢筋装车用的小型起重机抓取装置,包括下圆板、上圆板、驱动机构、挤压机构和施力反馈机构,通过吊车将本发明放置在盘绕钢筋的中间空心位置,接着启动电机,电机带动蜗杆转动,蜗杆通过与三个涡轮的啮合设置同时带动三个双头丝杆转动,双头丝杆的转动驱动同个双头丝杆上的两个螺母相互靠近移动,在连杆的连接作用下,挤压板会向外扩张并与盘绕钢筋的内侧挤压接触,通过插杆的设置,使得挤压板在挤压过程中将插杆带入赶紧的间隙中,使得在对钢筋进行吊运时提供稳定的支撑力,避免钢筋发生滑落的情况,提高了本发明的使用安全性;本发明中通过驱动机构和挤压机构的配合设置能够对盘绕钢筋进行快速稳定地抓取。
