Description

Device for maintaining gun barrel

Technical Field

the utility model relates to a cleaning device, in particular to a device for maintaining barrel.

Background

In the prior art, devices for cleaning the barrel of an artillery generally comprise: the cleaning head, the rotating rod and the driver, the driver drives the cleaning head extending into the gun barrel to rotate by the rotating rod so as to clean the attachments on the inner wall of the head of the gun barrel.

In order to reduce the damage of the cleaning head to the inner wall of the gun barrel when the cleaning head cleans the gun barrel, for example, the diameter of the inner wall of the gun barrel is increased, in the prior art, the hardness of a cleaning layer of the cleaning head is smaller than that of the inner wall of the gun barrel, and then the abrasion speed of the cleaning layer is larger than that of the inner wall of the gun barrel, so that the damage of the inner wall of the gun barrel can be effectively reduced.

However, the increase in the wear rate of the cleaning layer tends to increase the frequency of replacement of the cleaning head, which is not because the outer layer of the cleaning layer is used up, but because the inner diameter of the cleaning head is too small to be suitable for cleaning because it is much smaller than the inner diameter of the gun barrel.

To maintain the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and components may be omitted.

As shown in fig. 1 and 2, the present invention discloses an apparatus for maintaining a gun barrel, the apparatus comprising: the cleaning head, the wand 60, the driver, the wand 60 and the driver are all of the same type and function as the wand 60 and driver of the prior art. The utility model discloses in, the cleaning head includes: retaining sleeve 10, cleaning block 20, tapered column 30, top nut 40, front end cap 11, rear end cap 12 and spring 50. The retaining sleeve 10 is formed by buckling two half sleeves, a plurality of guide grooves are formed in the retaining sleeve 10, and the plurality of guide grooves are uniformly distributed in the circumferential direction. The cleaning blocks 20 comprise a plurality of cleaning blocks which are the same as the guide grooves in number, the cleaning blocks 20 are respectively arranged in a penetrating mode in the guide grooves, a conical guide cavity 21 is formed by the inner sides of the cleaning blocks 20 in a surrounding mode, a cleaning layer 22 is formed on the outer side of each cleaning block 20, the cleaning layers 22 form the periphery of the cleaning head, and the cleaning head removes attachments on the inner wall of the gun barrel through the periphery. The conical column 30 extends from the head of the retaining sleeve 10 into the conical guide cavity 21. The front end cover 11 is arranged at the head of the retaining sleeve 10, a threaded sleeve 111 is formed on the front end cover 11, the top nut 40 extends into the threaded sleeve 111, and a top pillar 41 is formed on the top nut 40, the top pillar 41 is used for abutting against the conical pillar 30, so that the conical pillar 30 is in contact with the conical guide cavity 21.
