The invention provides a hydraulic auxiliary lifting device, and belongs to the technical field of intelligent cranes. The technical problem that a cylindrical object cannot be hoisted is solved. Thehydraulic auxiliary lifting device comprises a mounting frame, a first supporting piece and a second supporting piece, the first supporting piece and the second supporting piece are arranged on the left side and the right side of the mounting frame correspondingly, a pressurizing device is fixed to the mounting frame, a hook matched with an intelligent crane is arranged at the upper end of the pressurizing device, a hydraulic cylinder is fixed to the left side of the mounting frame, the first supporting piece is connected with a driving rod of the hydraulic cylinder, a liquid inlet of the hydraulic cylinder is communicated with the upper end of the pressurizing device through a liquid conveying pipe, and a valve capable of controlling on-off of the liquid conveying pipe is arranged in themiddle of the liquid conveying pipe. When the intelligent crane lifts the object, upward pulling force borne by the object is converted into supporting force in the horizontal direction, enough upwardfriction force is generated through the supporting force to resist the gravity of the object, therefore, the lifting action on the cylindrical object is achieved, the structure is simple, and stability is high.
本发明提供了一种液压式的辅助提升装置,属于智能吊技术领域。它解决了无法吊起筒状物件等技术问题。本液压式的辅助提升装置包括安装架以及分别设置于安装架左右两侧的第一支撑件和第二支撑件,安装架上固定有增压装置,增压装置的上端设有与智能吊配合的挂钩,安装架的左侧固定有液压缸,第一支撑件与液压缸的驱动杆相连,液压缸的进液口通过输液管与增压装置的上端部连通,输液管的中部设有能够控制输液管通断的阀门。本发明将智能吊吊取物件时该物件受到的向上拉力转化成水平方向的支撑力,并通过支撑力产生足够的向上摩擦力来对抗物件的重力,从而实现对筒状物件的吊取动作,结构简单,稳定性较高。
