Abstract
A hydraulic excavator in a coal mine comprises a rack provided with a running gear, a rotating support on the rack and a horizontal shaft. A working device formed by a big arm, a small arm and a bucket is hinged at the front end of the horizontal shaft, wherein the big arm, the small arm and the bucket are hinged in sequence. The big arm is provided with two sections, namely, a front section and a back section. A rotary connection device and a rotary driving device are connected between the front section and the back section. The horizontal shaft is connected with the rotary driving device. The rotary driving device connected with the horizontal shaft is provided with a round disc connected on the horizontal shaft. The outer periphery of the round disc and the upper face of the rotation side of the rotating support are connected with a rotary hydraulic cylinder. The hydraulic excavator in the coal mine not only can clear away inventories on the ground and conduct a bottom-cutting operation on the ground of a tunnel, but also can conduct a side-chopping operation on the lateral side of the tunnel and a top-removing operation on the ceiling of the tunnel. The small arm of the working device is in an integral structure without divided sections so that the small arm is strong in intensity. A driving device of the horizontal shaft is a rotary hydraulic cylinder connected in the radial direction of the horizontal shaft. The driving device of the horizontal shaft is low in manufacture and installation cost, high in usage safety and reliability and small in maintenance quantity.
