Technical Field

[0001] This utility model relates to the field of artillery technology, specifically a multi-functional barrel measuring instrument. Background Technology

[0002] In the field of artillery technology, the maintenance and inspection of gun barrels are crucial to ensuring the performance and safety of artillery. Traditional gun barrel inspection methods often rely on manual visual inspection or simple tools, which are not only inefficient but also difficult to accurately measure key parameters such as barrel curvature and expansion. With technological advancements, higher demands are placed on gun barrel inspection, requiring equipment capable of comprehensively and accurately measuring the condition of the gun barrel. However, existing measuring tools are often limited in function and cannot meet the needs of comprehensive gun barrel inspection.

[0003] Therefore, the development of a barrel measuring instrument that integrates multiple functions, capable of simultaneously measuring the barrel's curvature and expansion, and inspecting internal defects, has become an urgent need in this field. Utility Model Content

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0036] Example 1

[0037] This embodiment discloses a multifunctional tube body measuring instrument, including a central tube 1, and a plurality of detection rings 2 are provided on the central tube 1, the detection rings 2 being detachably connected to the central tube 1.

[0038] The central tube 1 is equipped with an expansion measuring component 3 at its tail end, and a 360° infrared camera 4 is located at the bottom of the expansion measuring component 3. The expansion measuring component 3 is equipped with wires for power supply and data transmission, which pass through the interior of the central tube and have a connector 11 at the front end of the central tube.

[0039] The central tube 1 is provided with multiple connecting parts 12 for connecting the detection ring 2. One side of the connecting part 12 is provided with a limiting ring 13, and the other end is provided with a threaded part 14 and a pressure ring 15 that mates with the threaded part 14. After the detection ring 2 is sleeved on the central tube 1 from one side, it is pressed and fixed from both sides by the limiting ring 13 and the pressure ring 15.

[0040] The expansion detection component 3 includes a connecting end 31, a guide part 32, and a measuring part 33. The connecting end 31 is screwed to the central tube 1.

[0041] The guide part 32 is a disc sleeved on the outside of the connecting end 31. The outer diameter of the disc is similar to the inner diameter of the gun barrel. The disc is detachably connected to the connecting end 31. A second pressure ring 34 is provided on the outside of the connecting end 31. The second pressure ring 34 is screwed to the connecting end 31 and presses the disc onto the expansion measuring component 3.

[0042] The measuring unit 33 includes a circular housing 331, and the outer surface of the housing 331 is provided with a measuring unit 332 and a zero adjustment knob 333; the measuring unit 332 is provided with a spring and a pressure sensor.

[0043] The central tube 1 is provided with a straight section 16. The straight section 16 can be used to place a level.

[0044] The measuring instrument is also equipped with a data display component 5, which is electrically connected to the expansion measuring component 3 via a connector 11 and a wire, and is used to display the pipe diameter data measured by the expansion measuring instrument 3 and the images captured by the 360° infrared camera.

[0045] The various functions of this utility model are described below:

[0046] 1. Measurement of pipe bending degree

[0047] As shown in the figure, the central tube 1 is a straight rod, and the diameters of each detection ring 2 on it are approximately the same as the inner diameter of the gun barrel. When the gun barrel 6 is not bent, the measuring instrument can pass through the gun barrel smoothly; however, when the barrel is bent, the measuring instrument cannot pass through the barrel.

[0048] 2. Measurement of tube expansion

[0049] Because this utility model has an expansion detection element 3 at its end, after zeroing, the measuring instrument is placed inside the barrel. The measuring part 332 is pressed against the inner wall of the barrel by the action of a spring. Therefore, during the pulling of the measuring instrument, the pressure sensor reading will change according to the barrel diameter. For example, as shown in the figure, when the inner wall of the barrel expands, the measuring part 332 will change its reading as it passes through the expansion point, thereby achieving the purpose of measuring the barrel expansion. The reading monitored by the pressure sensor can be displayed on the data display component 5.

[0050] 3. Detection of internal defects in the gun barrel

[0051] This invention features a 360° infrared camera at the end of the expansion detection component 3, which can photograph the inner wall of the gun barrel and quickly detect defects such as ablation marks. The captured images can be displayed on the data display component 5.

[0052] 4. Muzzle leveling check

[0053] When this invention is inserted into the gun barrel, the leveling section 16 can be moved to the muzzle position. Then, the level 7 is placed on the leveling section 16 to check the levelness of the muzzle.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
