我室是一个正在筹建中的矿山科研单位,在英明领袖华主席“抓纲治国”的伟大战略决策鼓舞下,我们深入狠揭猛批“四人帮”,在有关单位的支持下,坚持边筹建,边搞科研。为加速实现矿山平巷掘进的高效率、高速度,我们自行设计制造了液压立爪式装岩机,自1976年9月到现在,在2.4×2.7M~2的主要运输平巷开拓工程中进行了试验,试验表明,对该机实行三班连续作业,除间断进行维修外,不断进行试验,装岩达3000M~3以上。这台装岩机的性能良好、效率高、作业安全、操作简易、劳动强度低、适合在坑下(高)大于2.2M;(宽)2.2～2.8M的平巷中作业。这台液压立爪装岩机的工作原理是:机器前端装有两只由液压控制,同步运行
Inspired by the great strategic decision of Chairman Hua, who wise leader is “grasping the basic rule of the country,” we are going to criticize and severely criticize the “Gang of Four,” and with the support of the relevant units, we insist on building a scientific and technological research institute, Engage in scientific research. In order to speed up the high efficiency and high speed of mine roadway driving, we design and manufacture the hydraulic vertical claw rock loader. Since September 1976 till now, in the main transport laneway project of 2.4 × 2.7M ~ 2 Carried out tests, tests show that the implementation of the machine three consecutive operations, in addition to intermittent maintenance, continuous testing, loading up to 3000M ~ 3 rock. This rock loader with good performance, high efficiency, safe operation, easy operation, low labor intensity, suitable for pit (height) is greater than 2.2M; (width) 2.2 ~ 2.8M Lane job. The working principle of hydraulic hydraulic claw rock loader is as follows: the front of the machine is equipped with two hydraulic control, synchronous operation
