北京煤机厂生产的ZM Z_2—17型装煤机在煤巷掘进时使用效果好。但是,在装煤机安装使用之前,最大的困难问题是本机运输。如,本机中最宽的部件是装煤台,在装煤爪曲柄园盘处机体最宽为1460毫米(这个宽度比架线式电机车宽400毫米以上),高为1030毫米,长为2170毫米,重量约为1100公斤。在中小型煤矿,巷道断面较小,特别是在巷道拐弯处,平放在车盘上的装煤台很容易被卡住,很难通过。如将其宽度方向改为竖直放置,又容易触碰架空线,极不安全;当需要通过风门时,还需拆掉风门、风墙,待机器过去后重垒。由于运输困难,工
ZM Z_2-17 coal charging machine produced by Beijing Coal Factory has good effect when heading in coal roadway. However, the biggest difficulty before the installation of a coal loader is local transport. For example, the widest part of the machine is the coal loading station, with a maximum body width of 1460 mm at the crankshaft of the coal charging claw (this width is 400 mm wider than the overhead motor vehicle), 1030 mm high and 2170 mm, weighs about 1100 kg. In small and medium-sized coal mines, roadway cross-section is small, especially in the corner of the roadway, flat on the car plate loading station is easy to get stuck, it is difficult to pass. If the width direction is changed to be vertical and it is easy to touch the overhead line, it is extremely unsafe. When it is needed to pass through the damper, the damper and the wind wall need to be removed, and the machine will pass through the heavy barrier when it passes. Due to transportation difficulties, workers
