Description

Technical Field

[0001] The invention relates to the technical field of artillery maintenance, and in particular to a hydraulic universal artillery maintenance stand. Background Art

[0002] Cannon refers to the use of mechanical energy, chemical energy (gunpowder), electromagnetic energy and other energy to project projectiles. The range exceeds the range of individual weapons. It consists of two major parts: the barrel and the gun carriage. The rifling of the cannon barrel is also called the windmill line. The rifling can be said to be the soul of the barrel. The function of the rifling is to give the bullet the ability to rotate, so that the bullet can still maintain a predetermined direction after leaving the barrel.

[0003] After the artillery is used, the burning gunpowder will release a lot of heat. The high temperature will burn the rifling of the artillery barrel, causing the rifling to be blocked by gunpowder residue. Therefore, the artillery barrel must be maintained and repaired regularly;

[0004] The artillery maintenance stand is a necessary tool for the maintenance and repair of gun barrels. Its purpose is to support the lifting of disassembled gun barrels and serve as a maintenance platform for the convenience of staff operation. However, different types of artillery barrels have different calibers and are relatively long. Moving the barrel is time-consuming and laborious, making it difficult to maintain or repair the obstructed parts of the barrel. At present, it is not possible to mechanically remove the slag from the rifling of gun barrels of different calibers, resulting in low rifling cleaning efficiency and long maintenance cycles. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art that the gun barrel is inconvenient to move, the shielding parts are difficult to repair and maintain, and the rifling slag cannot be removed for gun barrels of different calibers, the technical problem to be solved by the present invention is a hydraulic universal artillery maintenance stand.

[0007] The purpose is to drive the guide wheel to move inward and clamp the barrel through the guide wheel. The clamping mechanism includes: a base, fixedly connected to the right end of the upper surface of the platform along the front-to-back direction; a guide rod, fixedly connected to the top of the inner cavity of the base along the front-to-back direction; a first motor, installed on the front side of the base; a screw, one end of which is installed on the output end of the first motor, and the other end is connected to the rear side of the inner cavity of the base through a bearing; two moving blocks, which are respectively screwed on the front and rear ends of the outer wall of the screw, and the moving blocks are sleeved on the outer wall of the guide rod; four support frames, each two of which are installed in a group at the left and right ends of the upper surface of the moving block, and the two support frames facing each other are symmetrically arranged front and back; a guide wheel is rotatably installed in the inner cavity of the support frame through a bearing.

[0008] Preferably, the threads on the front and rear sides of the outer wall of the screw are positive and negative threads.

[0011] Preferably, the second connecting rod is located at the outer edge of the upper surface of the first rotating disk.

[0012] Preferably, the purpose is to mechanically clean the residues produced by the combustion of gunpowder in the rifling of the barrel to ensure the effect of the rifling on the fired shells, and the slag removal mechanism includes: an outer shell, which can be rotatably installed on the output end of the push hydraulic cylinder; a third motor, which is installed on the left side of the inner cavity of the outer shell; a second turntable, which is installed on the output end of the third motor; a threaded line, which is installed on the right side wall of the second turntable; a number of limit cylinders, which are respectively fixedly connected to the right side of the outer wall of the outer shell; a limit rod, which can be slidably inserted into the inner cavity of the limit cylinder; a number of teeth, which are all installed on the inner side of the left side wall of the limit rod, and the teeth are meshed with the threaded line; a slag removal block, which is fixedly connected to the outside of the limit rod.

Under the traction of the second connecting rod, the first turntable drives the guide wheel to rotate, so that the two guide wheels relative to each other rotate in the opposite direction.

The position of the slag removal block is changed according to the caliber of the barrel, and the rifling of barrels of different calibers can be mechanically removed. The rifling cleaning efficiency is high and the maintenance cycle is shortened. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The clamping mechanism 5 includes a base 51, a guide rod 52, a first motor 53, a screw 54, a moving block 55, a support frame 56 and a guide wheel 57.

The outer shell 91 is rotatably installed on the output end of the push hydraulic cylinder 8; the third motor 92 is installed on the left side of the inner cavity of the outer shell 91, and the third motor 92 is a forward and reverse motor for driving the second turntable 93 to rotate clockwise or counterclockwise; the second turntable 93 is installed at the output end of the third motor 92; the threaded wire 94 is installed on the right side wall of the second turntable 93, and the threaded wire 94 rotates under the drive of the third motor 92, and the threaded wire 94 can make the limiting rod 96 rotate by turning the teeth 97 96 moves, when the thread line 94 rotates clockwise or counterclockwise, the thread line 94 can move the limit rod 96 inward or outward by toggling the teeth 97; there are a number of limit tubes 95, which are respectively fixedly connected to the right side of the outer wall of the shell 91, and play a limiting role on the limit rod 96 to prevent the limit rod 96 from rotating; the limit rod 96 can be slidably inserted into the inner cavity of the limit tube 95; there are a number of teeth 97, all of which are installed on the inner side of the left side wall of the limit rod 96, and the teeth 97 are meshed with the thread line 94; the slag removal block 98 is fixedly connected to the outer side of the limit rod 96, and the slag removal block 98 is made of metal with higher hardness and is used to scrape off the gunpowder combustion residue remaining in the rifling of the barrel;

[0033] According to the caliber of the barrel, the second turntable 93 is driven to rotate clockwise or counterclockwise by the third motor 92, thereby rotating the thread line 94. Since the thread line 94 is meshed with the teeth 97, the rotation of the thread line 94 can drive the limit rod 96 to move inward or outward along the limit tube 95. The circular diameter formed by several slag removal blocks 98 can change according to the barrel rifling, allowing the slag removal blocks 98 to enter the barrel rifling, and the outer shell 91 is pushed left and right by pushing the hydraulic cylinder 8.
