Description

Technical Field

[0001] This utility model relates to the field of artillery maintenance equipment, and in particular to a solid grease liquefaction spraying device for artillery barrels. Background Technology

[0002] During the maintenance and storage of artillery, lubricating grease is applied to the inside of the gun barrel to prevent rust and lubricate it. Commonly used lubricating grease is solid at room temperature and has poor fluidity, so it needs to be heated and liquefied before being sprayed. After being heated, the lubricating grease dissipates heat quickly through the pipeline and is prone to solidifying again, which affects the spraying efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a solid grease liquefaction spraying device for gun barrels. By setting a heating chamber to heat the grease, the grease can be sprayed more smoothly from the nozzle, and the grease can be sprayed more evenly on the inner wall of the gun barrel. It is simple and convenient to operate and has a very high working efficiency.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a solid lubricating grease liquefaction spraying device for gun barrel, including a support assembly and a spraying assembly;

[0005] The support assembly includes a main body and a plurality of pulleys distributed around the periphery of the main body;

[0006] The spray assembly includes a heating chamber, a nozzle, and a ceramic heating module;

[0007] The heating chamber is disposed on the main body, the rear end of the heating chamber is connected to the liquid supply pipe, the front end of the heating chamber is connected to the nozzle, and a plurality of ceramic heating modules are disposed around the heating chamber.

[0008] The main body is placed inside the gun barrel by pulleys and moves in a straight line along the gun barrel. The grease is delivered to the heating chamber by a pump. The heating chamber is equipped with a ceramic heating module on the side wall, which can heat the grease in the heating chamber, so that the grease is melted and then sprayed outward from the nozzle onto the inner wall of the gun barrel.

[0009] Preferably, the ceramic heating module is embedded in the side wall of the heating cavity. This facilitates the transfer of heat from the ceramic heating module into the heating cavity.

[0010] Preferably, the main body has a cylindrical structure, and the heating cavity is disposed within the inner cavity of the main body. This facilitates the fixing of the heating cavity.

[0011] Preferably, a variable diameter mechanism is provided between the pulley and the main body to facilitate adaptation to gun barrels with different inner diameters.

[0012] Preferably, the diameter-changing mechanism includes a fixed ring seat, a movable ring seat, an adjusting nut, and several sets of support members;

[0013] The fixed ring seat is disposed at the first end of the main body, and the movable ring seat is slidably fitted at the second end of the main body. The second end of the main body is provided with an external thread section, and the adjusting nut is threadedly adapted to the external thread section. The adjusting nut pushes the movable ring seat to slide towards the first end. The fixed ring seat and the movable ring seat are connected by a number of sets of support members. The pulley is disposed on the support member. When the movable ring seat approaches the fixed ring seat, the support member deforms, causing the diameter of the pulley to increase.

[0014] By rotating the adjusting nut, the movable ring seat is pushed, which in turn squeezes the support, making the diameter of the pulley larger, so as to accommodate a larger inner diameter gun barrel.

[0015] Preferably, the support member includes a first support arm and a second support arm. One end of the first support arm is hinged to the fixed ring seat, and the other end of the first support arm is provided with a pulley. One end of the second support arm is hinged to the movable ring seat, and the other end of the second support arm is also provided with a pulley. The middle portions of the first and second support arms are hinged relative to each other. When the movable ring seat approaches the fixed ring seat, the first and second support arms push outwards in a cross motion, thereby completing the diameter change.

[0016] Preferably, the support members comprise three sets, which can provide more stable support.

[0017] Preferably, the nozzle is an atomizing nozzle, which increases the area of ​​spray lubrication.

[0018] The beneficial effects of this utility model are:

[0019] This solution, by setting up a heating chamber to heat the grease, facilitates the smoother spraying of the grease from the nozzle, and allows for more even spraying of the grease onto the inner wall of the gun barrel. It is simple and convenient to operate and has very high work efficiency. Attached Figure Description

[0027] The main body 1 is placed inside the gun barrel by pulley 9 and moves in a straight line along the gun barrel. The grease is pumped to the heating chamber 2. The side wall of the heating chamber 2 is equipped with a ceramic heating module 3, which can heat the grease in the heating chamber 2, so that the grease is melted and then sprayed outward from the nozzle 4 onto the inner wall of the gun barrel.

[0028] The ceramic heating module 3 is embedded in the side wall of the heating cavity 2, facilitating the transfer of heat from the ceramic heating module 3 into the heating cavity 2.

[0029] The main body 1 adopts a cylindrical structure, and the heating cavity 2 is disposed in the inner cavity of the main body 1. This facilitates the fixing of the heating cavity 2.

The middle portions of the first support arm 8 and the middle portions of the second support arm 7 are hinged relative to each other. When the movable ring seat 6 approaches the fixed ring seat 5, the first support arm 8 and the second support arm 7 push outwards in a cross motion, thus completing the diameter change. The support component includes three sets, providing more stable support.

[0035] The nozzle 4 is an atomizing nozzle, which increases the area for spraying lubrication.

[0036] The beneficial effects of this utility model are:

[0037] This solution uses a heating chamber 2 to heat the grease, which allows the grease to be sprayed more smoothly from the nozzle 4 and more evenly onto the inner wall of the barrel. It is simple and convenient to operate and has very high work efficiency.
