一种用于掘进机机载锚索张拉机具的自动增压装置,能有效地控制锚索张拉机具的运行速度,提高井下锚索支护及掘进工作效率。该装置由冀中装备集团石煤机公司技术中心研发成功,并应用于该公司生产的EBZ150半煤岩掘进机上。使用锚索支护时要用到锚索张拉机具,而以往的外置张拉机具普遍存在流量小、效率低、占用人员多、工人劳
An automatic supercharging device used for the boring machine airborne anchor cable tensioning device can effectively control the operating speed of the anchor cable tensioning device and improve the work efficiency of underground anchor cable support and driving. The device by the Jizhong Equipment Group Stone Company Technology Center successfully developed and applied to the company’s EBZ150 semi-coal boring machine. When using the anchor cable support, it is necessary to use the anchor cable tensioning device, whereas the conventional external tensioning device is ubiquitous with small flow rate, low efficiency and occupying more workers.
