蟹爪式装煤机是煤矿里应用较为广泛的一种连续装载设备,其特点是能在较小断面的巷道内工作,并且效率高,机动性强,操作方便等。在井下作业的装煤机,作业条件十分恶劣,要对蟹爪式装煤机在井下装煤过程中的一些参数(例如生产率、蟹爪的驱动功率、机器的牵引力与蟹爪每分钟摆动次数之间的关系)进行测试是相当困难的,要作这样的试验需要大量的材料和经费。为此,我们 Crab claw loader is a kind of continuous loading equipment which is widely used in coal mines. It is characterized by being able to work in roadway with small section and high efficiency, strong maneuverability and easy operation. Working coal mine downhole, operating conditions are very poor, the crab claw loader coal charging process in the process of some of the parameters (such as productivity, crab claw driving power, the machine’s traction and crab claws per minute swings The relationship between) is very difficult to test, to be such a test requires a lot of materials and funding. For this, we
