Abstract

A device for pulling out the stuck dud shells contains a square base, a top frame, mounted between the traction clamping mechanism, interacting with the shell, a rod connecting the base with the upper frame, lower, in the form of a circle, a frame formed with four diametrically disposed heads interconnected by arcs. In the heads of the threaded holes with installed screws with lock nuts, with the possibility threaded ends to enter in the technological trenches, placed on the outer surface of the projectile. Thrust in the form of struts with the upper frame are connected rigidly, but with a rectangular lower base ends and a middle part, with additionally installed braces, hinged. Frame is made out of the first and second parts, divided by a horizontal septum, of which the first part is on the bulkhead on the motor. The motor is coupled to a source of electric power associated with it through the coupling, reducer, the output shaft of which is mounted the driving toothed gear which is in mesh with a driven gear mounted on the shaft of the winch drum, placed in the second part of the upper frame. Associated with the drum at one end of the traction cable, the opposite end via the additionally installed hard thrust, coupled with four associated arcs heads of the locking mechanism of the projectile. On the threaded tips of the screws hinged arc plate, the inner surface of which is equipped with tilted up sharp notches, with the ability to interact with the outer surface of the projectile.
