Abstract
The invention discloses a cart walking trolley with a broken shaft protection device. The cart walking trolley comprises a balance beam 1, a half hinge 2, a trolley frame 6, a driving motor 9, a driving motor bracket 11, a motor protection frame 12, a driving shaft 4, a driven shaft 5, the broken shaft protection device 3, a driving wheel 7, a driven wheel 8, a hinge support 10, a baffling block I 13, a baffling block II 14 and a rail 15. The broken shaft protection device and a wheel on the other one unbroken driven shaft or driving shaft push against the rail, so that the trolley and parts above the trolley are temporarily and effectively supported to prevent a wheel on the broken shaft from directly pushing against an upper cover plate at the top of the trolley frame or to prevent one side of the lower part of the trolley frame from directly pushing against the rail to damage the trolley frame and even cause inclining or collapsing of a whole crane, and the whole trolley is effectively protected. Furthermore, gaps between the two sides of a groove of the broken shaft protection device and the rail are smaller than gaps between the two sides of rims of the driving wheel and the driven wheel and the rail, so that the abrasion of the wheels and the rail is prevented or alleviated, the service life of the wheels is prolonged, and the replacing frequency of the wheels is reduced.
