Description

Portable bore oiling station

Technical Field

The utility model relates to a technical field is maintained in the maintenance of artillery, especially relates to a portable bore oiling station.

Background

Artillery is an important combat weapon in modern war, and is used for launching artillery shells to kill and destroy enemy vitality, defense works and the like. The traditional gun is characterized in that a rifling gun or a smooth-bore gun adopted by modern military affairs is launched by chemical energy, so that flame and smoke emerge during each firing of the gun, meanwhile, some gunpowder residues are remained in the gun bore, and a layer of paint black residues are remained in the gun bore in the past.

The bore of the large-scale artillery needs to be cleaned and maintained when the bore is unsealed or sealed and after the cannonball is launched because the bore is not cleaned completely, copper hanging and carbon deposition are caused, and the movement of the shot in the bore is blocked, so that bore explosion occurs. And cleaning the bore, including removing foreign matters in the bore and performing rust prevention treatment on the bore. The foreign matter in the bore includes metal such as copper, zinc, lead, and aluminum, oxidation residue of aluminum, and combustion residue of the explosive in the bore, such as soot and graphite attached to the inner wall of the bore, which are detached from the projectile, and foreign matter generated by rusting in the bore. The foreign matter is liable to block and corrode the inner wall of the bore, which aggravates the wear and corrosion of the inner wall of the bore. Especially in the course of firing the artillery, residues (carbon deposits) attached to the inner wall of the bore, which are generated at high temperature and high pressure, are tightly bonded with the bore; in addition, because the length of bore is greater than bore inner wall diameter far away again, consequently, the residue not only can influence the shooting precision, still can reduce the barrel life-span, consequently, wash the bore and be a very important work, also be one of the indispensable procedure of artillery daily maintenance, the artillery need wash and fat liquoring protection to the bore after using.

However, the currently used oiling technology is still manual oiling, and cloth strips are tied on a long rod and are dipped with grease and then wiped back and forth on the inner wall of the gun barrel. This kind of bore fat liquoring not only has the problem that wastes time and energy, and the fat liquoring is inhomogeneous moreover, causes the very big waste of grease, and in addition, to the barrel that has the rifling, there is the unable condition of scribbling the oil of rifling root even to lose the safeguard effect.
