The invention relates to the technical field of building production, and discloses a waste paper recovery pretreatment device. The waste paper recovery pretreatment device comprises a crane boom; a storage sleeve is hinged to the bottom of the left end of the crane boom, and the bottom ends of the front inner wall and the rear inner wall of the storage sleeve are both provided with skewed slots, and the left ends of the interiors of the skewed slots are fixedly connected with first telescopic rods; one ends of the first telescopic rods are fixedly connected with supporting arms, and the two opposite surfaces of the two supporting arms are fixedly connected with the front end and the rear end of a transverse rod correspondingly, and a user can conveniently hang a lifting hook on the transverse rod; the storage sleeve is rotated by 90 degrees under pull force of a second telescopic rod and connected to the bottom of the outer wall of the crane arm in a sleeving mode, so that a driver hasa wide visual field to observe the road condition, and in addition, the situation that normal running of surrounding vehicles is influenced by the lifting hook is avoided; when the vehicle is drivenon an uneven road surface, the lifting hook is clamped in the middle by two baffles and buffer springs, thus, the lifting hook is conveniently limited, the left-right swing amplitude of the lifting hook is reduced, and the situation that the running stationarity of the vehicle is influenced by large-amplitude left-right swing is avoided.
本发明涉及建筑生产技术领域,且公开了一种废纸回收预处理装置,包括起重臂,所述起重臂左端的底部铰接有收纳套,所述收纳套前后内壁的底端均开设有斜槽,所述斜槽内部的左端固定连接有第一伸缩杆,所述第一伸缩杆的一端固定连接有支撑臂,两个所述支撑臂相对的两面分别与横杆的前后两端固定连接,便于使用者将吊钩挂在横杆上,收纳套在第二伸缩杆的拉力下转动90°并套接在起重臂外壁的底部,使得驾驶人员有开阔的视野观察路况,且避免吊钩影响周边车辆的正常行驶,车辆在不平的路面上行驶时,两个挡板和缓冲弹簧将吊钩夹在中间,便于对吊钩进行限位和减缓吊钩的左右摇摆幅度,避免吊钩大幅度的左右摇摆影响车辆的行驶平稳性。
