Tensioner for cleaning tank gun bore

Abstract

The invention discloses a tensioner for a cleaning tank gun bore. The tensioner for the cleaning tank gun bore comprises a front tensioning assembly connected to a spray brush head, a main shaft and arear tensioning assembly connected with the main shaft, wherein the main shaft penetrates through the front tensioning assembly and the rear tensioning assembly; the end of the rear tensioning assembly is provided with a guiding rail; the central axis of the main shaft is provided with a first air intake pipe leading to the spray brush head, a second air intake pipe leading the end of the front tensioning assembly, and a third air intake pipe leading to the rear tensioning assembly; the end of the first air intake pipe is provided with a first air outlet; the end of the second air intake pipeis provided with a second air outlet; the end of the third air intake pipe is provided with a third air outlet; each start end of the first air intake pipe, the second air intake pipe and the third air intake pipe is connected with an air inlet connection; and each air inlet connection is fixedly arranged on the guiding rail and connected with a corresponding air cylinder. By means of the tensioner, the spray brush head can be fixedly combined with the wall of a pipe, and the friction with the wall of the pipe is increased through the arrangement of a tensioning piece, so that the contact area is increased, the structure is simple, and tension and reset are achieved.

Description

technical field [0001] The invention relates to the technical field of tank gun bore cleaning equipment, in particular to a tensioning device for tank gun bore cleaning. Background technique [0002] In modern warfare, science and technology are widely used in the upgrading and development of weapons. While seeking better science and technology to help weapons improve combat effectiveness and battlefield survivability, military experts are developing new weapons and trying to destroy them in battle. Tanks, a heavy-duty high-tech weapon, have always been called killers by military experts on the battlefield because of their powerful combat effectiveness and deterrence. As we all know, tanks not only have powerful fire control capabilities, but also have excellent protective armor so that some conventional shells and anti-tank missiles cannot cause damage to it. With the development of science and technology, tanks have higher and higher anti-strike capabilities of protective...
