Abstract:
An apparatus for cleaning a gun barrel having striations formed on an inner surface of the gun barrel includes a cleaning means that is in contact with the inner surface of the gun barrel as being moved by a drive means installed inside a cylindrical main body. The cleaning means includes a main member having a circular plate on which a plurality of insertion holes is formed along its circumference; a rotating member formed inside the circular plate and having a motor and a rotating gear interlocking with the motor; and cleaning members formed to be inserted into the insertion holes, respectively, to clean the inner surface of the gun barrel and having lower sides interlocking with the rotating gear, respectively, to be rotated. The apparatus for cleaning a gun barrel is rotated at high speed with an appropriate pressure along the groove part of the gun barrel accurately, and thus a wide area can be cleaned in a short time. Even if the brusher is worn out, an appropriate pressure is maintained by the spring, and thus the amount of wear is compensated for. Since the brusher does not secede from the barrel, the accuracy is increased, and since the respective brushers are replaceable and it is not required to replace the whole cleaning member, the cost is saved.
Abstract:
An apparatus for cleaning a gun barrel having striations is provided, which can uniformly clean an inner surface of the gun barrel by making cleaning members in contact with the inner surface of the gun barrel. The apparatus includes a cleaning device being in contact with the inner surface of the gun barrel as it is moved by a drive device installed inside a cylindrical main body. The cleaning device includes a plurality of divided plates dividedly provided inside the gun barrel in the form of a saddle and being slanted to correspond to a slope of the striations, cleaning members fixed to outer peripheries of the respective divided plates and being in contact with the inner surface of the gun barrel, a cam device converting a rotation of a drive motor installed inside the main body into a rectilinear movement in order to move the respective divided plates upward/downward, and a direction changing part coupling the cam device to the divided plates so that the divided plates go and return along the striations formed on the inner surface of the gun barrel and distributing a frictional force according to the movement of the divided plates forward/backward.
Abstract:
An apparatus for cleaning a gun barrel having striations, which includes a cleaning device that comes in contact with the inner surface of the gun barrel as it is moved by a drive device installed inside a cylindrical main body. The cleaning device includes (i) a plurality of divided plates that fit atop the striations as a saddle and are slanted to correspond to a slope of the striations, (ii) cleaning members fixed to outer peripheries of the respective divided plates that come in contact with the inner surface of the gun barrel, and (iii) a cam device that converts a rotation of a drive motor installed inside the main body into a rectilinear movement in order to move the respective divided plates upward and downward.
Abstract:
An apparatus for removing a dud is disclosed, which makes it possible to safely remove a dud from various kinds of guns used as long-range firepower when a shell is caught in the inner diameter of a gun barrel and thus is not discharged. The apparatus includes a forward driving means providing a propulsive force for forwarding the apparatus along an inner surface of a gun barrel, a press driving part directly connected to the forward driving means and having a built-in motor to provide a rotating force, a sticking means connected to the press driving part and extended to an outside to be tightly stuck on the inner surface of the gun barrel by a main shaft being rotated by the motor, and a pushing part having one end part connected to the sticking means and the other end part coupled to a cap that is in contact with the dud, and pushing the cap through a forward movement of the main shaft after the sticking on the inner surface of the gun barrel is performed by the sticking means.
Abstract:
An automatic cleaning apparatus for a gun barrel is disclosed, which includes a wheel contacting an inner surface of the gun barrel and a brush or non-woven fabric rotating against the inner surface of the gun barrel which is applied with a cleaning solution or anti-corrosive oil, and moves forward by rotation of the wheel. The automatic cleaning apparatus includes a gear housing interposed between a front wheel and a rear wheel which are rotated in cooperation with a motor, and having a penetrated axial center part, a main shaft installed in the center part of the gear housing, and coupled to the motor and rotated by the motor, a sun gear disposed in a direction perpendicular to an axial direction of the gear housing, and coupled to the main shaft, a plurality of planetary gears positioned in a through-hole formed on the gear housing, restrained by a fastening bolt to mesh with the sun gear to rotate on its axis, and an external gear meshed with outer surfaces of the planetary gears, the brush or non-woven fabric being detachably engaged to the external gear.
