我国框架式液压支架搬运车装备与关键技术发展综述

Review of equipment and key technology development of frame-type hydraulic support carrier in China

为改变依赖进口支架搬运车的现状,随着对进口装备的技术研究和使用经验的不断积累,结合我国综采工作面搬家倒面工艺,对大功率防爆柴油机技术、带湿式制动的轮边减速器技术、链轮+圆环链敞开式载荷提升技术、矿用重载实心轮胎压力释放技术等多项关键技术进行了难点攻关、适应性改进和自主创新,实现了相关技术的零壁垒,部分技术已经处于领先水平。经过十余年的发展,我国框架式支架搬运车的系列化车型已经实现了30~100t载重范围的全覆盖,技术先进,性能稳定,满足了我国煤炭生产企业的使用需求。随着国家煤炭开采战略的转移和蓄电池动力等技术的进步,未来框架式支架搬运车装备将会在薄煤层和纯电动等方向上有更大的发展。

With the continuous accumulation of technical research and application experience of imported equipment, combining with the moving and reversing technology of fully mechanized coal mining face in China, the crucial problems of the key technologies, such as high-power explosion-proof diesel engine technology, wheel reducer technology with wet brake, sprocket+ring chain open load lifting technology, mining heavy-duty solid tire pressure release technology, etc., are tackled, the technological adaptability is improved and independent innovation is carried out, eliminating the related technology barriers, and some of the technologies are already in the leading position. After more than ten years’ development, the series models of the frame support carrier in China have fully covered the 30~100 t load range, with its advanced technology and stable performance, the requirements of coal production enterprises in China is fully satisfied. With the shift of national coal mining strategy and the advancement of battery power technology, the future frame support carrier equipment will have greater development in thin coal seam and pure electric direction.
