The invention relates to the technical field of coal mine fully mechanized mining, in particular to a coal face large-mining-height hydraulic support overhauling device which comprises a base, lifting rods are fixedly connected to the left side and the right side of the upper surface of the base, a mounting plate is fixedly connected to the output ends of the upper surfaces of the lifting rods, and stand columns are arranged on the left side and the right side of the upper surface of the mounting plate in a rolled mode. Extension columns are movably connected into the upper surfaces of the stand columns, and extension assemblies are arranged on one sides of the stand columns. The extension assembly comprises a groove, the groove is formed in one side of the stand column, and a rotating shaft is rotationally connected to the interior of the groove. The extension assembly is composed of the groove, the rotating shaft, a material collecting disc, a chain and a first connecting ring, when the extension assembly is used, a worker uses the rotating disc to rotate the rotating shaft, and the rotating shaft is driven to rotate; the chain in the material receiving disc can be tightened and put down, so that the expansion table can be put down, the maintenance space of workers is increased, and the workers can stand in the mounting plate conveniently during use.

    本发明涉及煤矿综采技术领域,具体为一种采煤工作面大采高液压支架检修装置,包括底座,底座上表面的左右两侧固接有升降杆,升降杆上表面的输出端固接有安装板,安装板上表面的左右两侧辊有立柱,立柱上表面的内部活动连接有延伸柱,立柱的一侧设有延伸组件;延伸组件包括凹槽,凹槽的位置设在立柱一侧的内部,凹槽的内部转动连接有转动轴,本发明通过延伸组件由凹槽、转动轴、收料盘、链条和第一连接环组成的,在使用的时候,由工作人员使用转动盘对转动轴进行运转,从而让在收料盘内的链条可以进行收紧和放下,从而使扩展台能够放下,从而增加工作人员维修的空间,而且使用的时候,还方便工作人员站在安装板内。
