一种综采工作面液压支架回撤设备

Fully-mechanized coal mining face hydraulic support retracting equipment

Abstract

The utility model relates to a set of fully-mechanized coal mining face hydraulic support retracting equipment. The retracting equipment mainly comprises an inclined arc platform, a main platform, walking structures, lug seat devices, a top prop, a guide wheel, a side prop and a lifting platform and is a retracting device of a coal mine fully-mechanized coal mining face complete set of equipment. The fully-mechanized coal mining face hydraulic support retracting equipment solves the problems that a pushing hydraulic cylinder of existing retracting equipment cannot be conveniently manufactured, the existing retracting equipment is huge in size and bolts for connection are prone to fracture. The fully-mechanized coal mining face hydraulic support retracting equipment is provided with lug seats, a hydraulic support is moved onto the retracting equipment through a pushing device of the hydraulic support, the equipment is provided with three lug seats which are used in sequence, and thus the hydraulic support can rotate by a certain angle. An inclined shovel plate and an arc platform are welded together, bolt connection is saved, and the structure is more compact and simpler. The inclined arc platform and the main platform are connected through wedge-shaped structures and hinge pins; the main platform and the lug seat devices are connected through wedge-shaped structures and hinge pins; the main platform and the lifting platform are connected through wedge-shaped structures and hinge pins, and thus connection is firmer. The fully-mechanized coal mining face hydraulic support retracting equipment has the advantages of being simple in structure and high in practicality.
本实用新型涉及一种综采工作面液压支架回撤设备,它主要由斜弧平台、主平台、行走结构、耳座装置、支顶、导向轮、支邻和抬升平台组成,属于煤矿综采工作面成套设备的回撤装置。它解决了现有回撤设备推移液压缸制造不便、体积庞大且螺栓连接易断裂的问题。本综采工作面液压支架回撤设备安装耳座,利用液压支架自身的推移装置使液压支架移动到回撤设备上,设备上有三个耳座,依次使用,使液压支架转动一定角度。斜铲板和弧平台焊接在一起,省去了螺栓连接,结构更加紧凑、简单。斜弧平台与主平台间用楔形结构和销轴连接;主平台与耳座装置间用楔形结构和销轴连接;主平台与抬升平台间用楔形结构和销轴连接,更加牢靠。本综采工作面液压支架回撤设备具有结构简单、实用性强的优点。
