The invention relates to the field of coal mine down-hole lifting equipment, in particular to a self-climbing-type four-hook hydraulic lifting device. The self-climbing-type four-hook hydraulic lifting device is used for disassembling and assembling coal mine down-hole fully-mechanized mining equipment. Two traveling foundations are oppositely and parallelly arranged, a lower box is mounted on each traveling foundation, the two lower boxes are oppositely and parallelly arranged, and vertical sleeves are mounted at the top of each lower box in the vertical direction, wherein every two verticalsleeves serve as a set; two inverted-U-shaped upper boxes are oppositely and parallelly arranged, the two inverted-U-shaped ends of the lower part of each upper box correspond to the vertical sleevescorrespondingly and are in sliding fit with the vertical sleeves, and the inner sides of the upper parts of the two upper boxes are connected through two opposite and parallel power unit fixing crossbeams to form a portal frame; lifting power units are arranged at the tops of the two power unit fixing cross beams, four lifting oil cylinders are arranged at the bottom of each lifting power unit, and the outer end of a telescopic rod of each lifting oil cylinder bypasses a chain wheel through a transmission chain A to be provided with a lifting hook; and a traveling oil cylinder and a self-contained track are mounted in each traveling foundation to form a self-climbing-type traveling foundation.

    本发明涉及煤矿井下起吊设备领域,具体为一种自爬式四钩液压起吊装置,用于煤矿井下综采设备的分解和组装。两个行走地脚相对平行设置,每个行走地脚上安装下箱体,两个下箱体相对平行设置,每个下箱体顶部沿竖向安装两个一组的立柱套筒,两个倒U型上箱体相对平行设置,每个上箱体下部的倒U型两端分别与立柱套筒相对应、并呈滑动配合,两个上箱体上部内侧之间通过相对平行的两个动力单元固定横梁连接,形成龙门架;两个动力单元固定横梁的顶部设置起吊动力单元,起吊动力单元的底部设置四个起吊油缸,每个起吊油缸的伸缩杆外端分别通过传动链A绕过链轮安装一个吊钩。每个行走地脚的内部安装行走油缸和自带轨道,形成自爬式行走地脚。
