Abstract

A gear-track-detachable driving device in a monorail crane for a steep slope includes a driving mechanism, a traveling mechanism, a four-bar linkage mechanism, a connection mechanism, a meshing track plate and transition track plates. The driving mechanism includes driving motors, meshing gears, a bearing rod, and a bearing plate. The traveling mechanism includes traveling wheels, clamping wheels, a shell and telescopic struts. The linkage mechanism includes first and second rockers, a linkage, and a cylinder. The connection mechanism includes fixation plates, a connection plate and connection bolts. When the crane travels to the slope front, the cylinder drives the linkage mechanism to send the meshing gears onto the transition track and adjusts the linkage mechanism into a dead point state, and the telescopic struts are locked. After the crane enters the slope, the meshing gears cooperate with the meshing track plate to provide an auxiliary drive for the crane.
