Abstract

The utility model relates to a linkage locking device of a garbage truck with a detachable compartment, which is mounted on a pulling arm mechanism; the pulling arm mechanism comprises a pulling arm, an overturn frame and a garbage truck compartment; the rear end of the pulling arm is hinged and fixed with the front part of the overturn frame; and main longitudinal beam compression channels are fixed on the two sides of the bottom part of the garbage truck compartment. The linkage locking device is characterized in that a linkage locking mechanism comprises a double-lock mechanism and a transverse locking mechanism. The utility model adopts a reasonable and novel structure and has strong practicability; when the linkage locking mechanism is in the full-extending state, the pulling arm and the overturn frame are connected into a whole via the double-lock mechanism; the garbage truck compartment is locked by the transverse locking mechanism, so that the garbage truck can work reliably; however, when the linkage locking mechanism is in the full-retracting state, the overturn frame and an auxiliary frame are connected into a whole via the double-lock mechanism; the overturn frame releases the pulling arm, so that the pulling arm can rotate freely; meanwhile, the transverse locking mechanism releases the garbage truck compartment, so the compartment can be lifted or lowered through the pulling arm; and the linkage locking device can also be applied to other similar machines and has high level of generalization.
