Description

Wiping brush for inner bore of directional tube of remote rocket gun

Technical Field

The utility model belongs to the field of gun maintenance, and particularly relates to a wiping brush for a bore of a remote rocket gun directional tube.

Background

The remote rocket gun is an important weapon system for army remote striking, and has the characteristics of long range, high precision, strong firepower, large coverage and the like. The remote rocket gun directional pipe is a main stressed carrier in the launching process, provides support and guiding functions for rocket projectiles, and endows a certain initial speed and shooting direction. The directional pipe is an important component in a remote rocket gun system, so that maintenance and maintenance work of the directional pipe in use, particularly maintenance and maintenance work of a directional pipe bore, are very important, and directly influence the service efficiency and service life of the remote rocket gun system.

Currently, the brush used for wiping the inner bore of the directional tube of the remote rocket gun is a pig bristle brush. The brush has certain effects in oil removal and oiling, but has unsatisfactory effects and efficiency in dirt removal and clean wiping. There are mainly the following problems:

firstly, the brush body is large in quality, short in service life and inconvenient to operate and use. Because the wooden brush seat body and the steel structural member are adopted, the quality of a single brush is very large, and the operation and the use are inconvenient. Meanwhile, the wooden brush base is not resistant to oil-water soaking, and the brush base is easy to deform and crack, so that the brush cannot be used and is scrapped.

Secondly, the bristle has small rigidity and poor dirt removing effect. The bristle of the bristle brush has good toughness, but has poor rigidity, when the bristle enters the bore, the lower bristles are fully pressed down, and the upper bristles are not contacted with the bore of the remote rocket gun (the overlapping amount of the bristles and the inner surface of the directional tube is small), so that the bristles cannot be fully contacted with the inner surface of the directional tube to generate friction in the bore wiping process of the bristle brush, and the wiping effect is poor and the working efficiency is low when the refractory stains such as rust and gunpowder residues are removed.

Thirdly, the single brush has long working wiping time and low efficiency. Because of structural design, the wiping brush equipped by the army at present can only work with a single brush, and can not work with several brushes connected in series, but the directional tube length of the remote rocket gun is long and the number of tubes is large, and a great deal of manpower and time are spent on general maintenance wiping or decontamination or clean wiping.
