Process and arrangement for introducing an automatic cleaning mechanism into a gun barrel

摘要

A process and arrangement for introducing an automatic cleaning device into the open end of a gun barrel so that the cleaning device may reciprocably move through the gun barrel and clean it. The cleaning device includes a drive motor, drive rollers, a pair of oppositely rotating brush members and sensing means. The arrangement for introducing the cleaning device into the gun barrel includes a lower trough-like member adapted to be joined to the muzzle of the gun barrel and an upper complementary member which jointly form a composite pipe member having essentially the same caliber than the gun barrel. A centering and tensioning mechanism is mounted on the muzzle of the gun barrel and serves to connect the composite pipe member to the gun barrel in axial alignment therewith. The cleaning device is positioned on the trough-like member and thereafter the complementary member is mounted on the trough-like member and connected thereto. The cleaning device is then introduced into the gun barrel in a last process step. The process and arrangement of the invention for introducing an automatic cleaning device can also be used to clean cylindrical surfaces other than gun barrels such as, for example, pipe lines which can be disassembled.
