The invention discloses a mining dump truck folding step ladder and a using method thereof, and belongs to the field of mining machineries. The mining dump truck folding step ladder comprises a folding ladder body connected with a small platform through a fixing plate, and a driving mechanism used for driving the fixing plate and the folding ladder body to rotate together is arranged in the smallplatform and comprises an oscillating cylinder, a flange plate, a long pin shaft and a short pin shaft; the oscillating cylinder is fixed on a support inside the small platform, the flange plate is fixed on a rotor of the oscillating cylinder, one end of the long pin shaft penetrates through the oscillating cylinder and is connected with the flange plate through a key, and the other end of the long pin shaft is inserted into the short pin shaft and fixedly connected with the short pin shaft, the opposite ends of the short pin shaft and the flange plate respectively extend to the outer parts ofthe corresponding sides of the small platform and are fixedly connected with the fixing plate on the side; and through the arrangement of an arc-shaped toothed bar, a driven gear, a driving chain wheel, a transmission chain, a driven chain wheel and a rotating shaft, a pedal can be driven to deflect. Deformation caused by collision between the step ladder and an obstacle on a mine road surface can be avoided, and people can conveniently get on the vehicle; and pedal can be protected.
本发明公开了一种矿用自卸车折叠蹬梯及其使用方法,属于矿用机械领域,包括通过固定板与小平台连接的折叠梯,小平台内设有用于驱动固定板和折叠梯一起转动的驱动机构,驱动机构包括摆动缸、法兰盘、长销轴、短销轴,摆动缸固定在小平台内部的支架上,法兰盘固定在摆动缸的转子上,长销轴的一端穿过摆动缸并通过键与法兰盘连接,长销轴的另一端插入短销轴内并与短销轴固定连接,短销轴和法兰盘的相背端分别延伸至小平台相应侧的外部并与该侧的固定板固定连接;并通过弧形齿条、被动齿轮、主动链轮、传动链、从动链轮及转动轴的设置,可带动踩踏板发生偏转。本发明既能避免蹬梯与矿山路面的障碍物相撞而变形,又能方便人员登车;且能防护踩踏板。
