Description

Technical Field

[0001] This utility model relates to the field of artillery recoil technology, specifically an artillery recoil device. Background Technology

[0002] The recoil mechanism connects the gun barrel and the gun carriage. Through the recoil motion of the gun barrel, the force acting on the gun barrel, which was hundreds of tons, is reduced to tens of tons acting on the gun carriage. This allows the gun to have great power while keeping the gun carriage very light, thus greatly alleviating the contradiction between the gun's power and mobility. Structurally, the recoil mechanism has three functions, specifically undertaken by three basic components. The first function is to dissipate the recoil energy during gun barrel recoil, stopping the gun barrel after it has recoiled a certain distance; this function is accomplished by the recoil brake. The second function is to store energy during gun barrel recoil, pushing the gun barrel forward to return it to its original position after recoil stops; this function is accomplished by the recoil mechanism. The third function is to dissipate energy during the recoil of the gun barrel, stopping it when it has returned to its original position; this function is accomplished by the recoil control mechanism. Domestic artillery often combines the recoil brake and recoil control mechanism into a single recoil mechanism, while placing the recoil mechanism separately. Countries like the United States typically combine all three basic components into a single recoil-return mechanism. No matter how they are combined, these three basic components of the recoil mechanism are indispensable, working together to complete the three functions of the recoil mechanism.

[0003] Regardless of whether a recoil mechanism and a return mechanism are used, or a recoil-return mechanism is used, there is currently a problem with artillery recoil systems: when the gun barrel and the return mechanism are connected by a connecting rod (there is one recoil mechanism and the return mechanism is located on the side of the gun barrel), the line of action of the force generated by the recoil mechanism is always misaligned with the axis of the barrel (the direction of barrel recoil and return movement). This causes the gun carriage to twist during recoil and return, resulting in a deviation of the aiming line, which is not conducive to continuous firing of the artillery. This problem is even more pronounced when the spade is not set properly (such as in soft soil). Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a recoil device for artillery in response to the above-mentioned shortcomings.

[0005] To solve the above technical problems, the present invention adopts the following technical solution:

[0006] A recoil mechanism for artillery includes a housing, a first recoil chamber, a second recoil chamber, and a third recoil chamber. The housing is mounted on the top of the gun barrel. The first recoil chamber is located in the middle of the housing. The second and third recoil chambers are located on the left and right sides of the first recoil chamber, respectively. The first, second, and third recoil chambers are all cylindrical and their axes are parallel to each other. A first recoil valve and a first recoil valve are provided between the first recoil chamber and the second recoil chamber. A second recoil valve and a second return valve are provided between the three recoil chambers. A traveling piston is provided inside both the second and third return chambers. The traveling piston separates the second and third return chambers into a compressed gas chamber and a hydraulic oil chamber. When the gun barrel is tilted upwards, the compressed gas chamber is located at the top of the second and third return chambers. The first recoil valve, the second recoil valve, the first return valve, and the second return valve are all connected to the hydraulic oil chamber. A pull rod is provided inside the first recoil chamber. The piston rod extends through the rear end of the housing and is fixedly connected to the gun cradle. When the gun fires, the piston rod moves backward, squeezing the hydraulic oil inside the first recoil chamber into the second and third recoil chambers. When the piston rod moves backward in the first recoil chamber, it pushes open the first and second recoil valves via hydraulic oil, delivering hydraulic oil to the hydraulic oil chambers of the second and third recoil chambers respectively. Simultaneously, it pushes the traveling piston backward, compressing the air in the compressed gas chamber. The gun barrel's backward movement distance is reduced. After the gun stops moving backward, the compressed gas chambers of the second and third recoil chambers are used to push the moving piston forward to squeeze the hydraulic oil chambers of the second and third recoil chambers. The hydraulic oil is then delivered to the first recoil chamber through the first and second recoil valves to push the gun barrel back to its original position. The first recoil valve, the second recoil valve, the first recoil valve, and the second recoil valve are all one-way valves. The inner sides of the second and third recoil chambers are equipped with inclined baffles for assisting recoil control.

[0007] Furthermore, the inclined baffle is installed inside the hydraulic oil chamber, and the upper end of the inclined baffle is tilted forward to enhance the flow resistance when the hydraulic oil chamber flows into the compressed gas chamber.

[0008] Furthermore, the housing is fixedly connected to the barrel by a retaining ring.

[0009] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0010] This invention mounts the recoil mechanism on top of the gun barrel. This structural design alters the line of force application, making the recoil mechanism's force application line closer to the bore axis compared to the traditional method of placing the recoil mechanism and the recoil arm on the side of the gun barrel. This reduces the torsion of the gun carriage during recoil and return, decreases the deviation of the aiming line, and facilitates continuous firing, especially in situations where the spade placement is not ideal, such as in soft soil. The inclined baffles inside the second and third recoil chambers enhance the flow resistance when hydraulic oil flows into the compressed gas chamber, thus assisting in recoil control and further optimizing the recoil performance of the recoil mechanism, contributing to better control of the gun barrel's recoil distance.

[0011] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0016] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0018] like Figure 1-2As shown, a recoil mechanism for artillery includes a housing 1, a first recoil chamber 2, a second recoil chamber 3, and a third recoil chamber 4. The housing 1 is mounted on the top of the gun barrel. The first recoil chamber 2 is located in the middle of the housing 1. The second recoil chamber 3 and the third recoil chamber 4 are located on the left and right sides of the first recoil chamber 2, respectively. The first recoil chamber 2, the second recoil chamber 3, and the third recoil chamber 4 are all cylindrical and their axes are parallel to each other. A first recoil valve 7 and a first recoil valve 8 are provided between the first recoil chamber 2 and the second recoil chamber 3. A second recoil valve 9 and a second return valve 10 are provided between the three return chambers 4. A traveling piston 6 is provided inside both the second return chamber 3 and the third return chamber 4. The traveling piston 6 is used to separate the second return chamber 3 and the third return chamber 4 into a compressed gas chamber 12 and a hydraulic oil chamber 13. When the gun barrel is tilted upwards, the compressed gas chamber 12 is located at the top of the second return chamber 3 and the third return chamber 4. The first recoil valve 7, the second recoil valve 9, the first return valve 8, and the second return valve 10 are all connected to the hydraulic oil chamber 13. The first recoil chamber 2 is provided inside... A pull rod piston 5 is provided, with its pull rod passing through the rear end of the housing 1 and fixedly connected to the gun cradle. The pull rod piston 5 can move backward upon impact during firing, squeezing the hydraulic oil inside the first recoil chamber 2 into the second recoil chamber 3 and the third recoil chamber 4. When the pull rod piston 5 moves backward in the first recoil chamber 2, it can push open the first recoil valve 7 and the second recoil valve 9 via hydraulic oil, delivering hydraulic oil to the hydraulic oil chambers 13 of the second recoil chamber 3 and the third recoil chamber 4 respectively. Simultaneously, it pushes the floating piston 6 backward, compressing the air in the compressed gas chamber 12. The gun barrel's backward movement distance is reduced. After the gun stops moving backward, the compressed gas chambers 12 of the second recoil chamber 3 and the third recoil chamber 4 are used to push the moving piston 6 forward to squeeze the hydraulic oil chambers 13 of the second recoil chamber 3 and the third recoil chamber 4. The hydraulic oil is then delivered to the first recoil chamber 2 through the first recoil valve 8 and the second recoil valve 10 to push the gun barrel to reset. The first recoil valve 7, the second recoil valve 9, the first recoil valve 8 and the second recoil valve 10 are all one-way valves. The inner sides of the second recoil chamber 3 and the third recoil chamber 4 are provided with inclined baffles 11 for assisting recoil control.

[0019] In one embodiment, the inclined baffle 11 is installed inside the hydraulic oil chamber 13. The upper end of the inclined baffle 11 is inclined forward and is used to enhance the flow resistance when the hydraulic oil chamber 13 flows into the compressed gas chamber 12.

[0020] In one embodiment, the housing 1 is fixedly connected to the barrel by a fixing ring 14.

[0021] In this utility model, the first recoil valve 7 and the second recoil valve 9, and the first return valve 8 and the second return valve 10 are symmetrically arranged. The first recoil valve 7, the second recoil valve 9, the first return valve 8 and the second return valve 10 are all existing one-way valves.

[0022] The working process of this utility model is as follows: The gun barrel moves backward under the action of the propellant gas, driving the pull rod piston 5, which is fixedly connected to the gun cradle, to move backward in the first recoil chamber 2, compressing the hydraulic oil in the first recoil chamber 2. Under pressure, the hydraulic oil compressed in the first recoil chamber 2 enters the hydraulic oil chambers 13 of the second recoil chamber 3 and the third recoil chamber 4 through the first recoil valve 7 and the second recoil valve 9, respectively. The hydraulic oil pushes the traveling piston 6 in the second recoil chamber 3 and the third recoil chamber 4 to move, compressing the gas in the corresponding compressed gas chamber 12. During this process, the flow of hydraulic oil is enhanced by the oblique baffle 11, which increases the flow resistance and assists in recoil control, thereby consuming the recoil kinetic energy of the gun barrel and reducing the backward movement distance of the gun barrel. When the recoil of the gun barrel stops, the gas in the compressed gas chamber 12 expands, pushing the traveling piston 6 to move in the opposite direction, pushing the hydraulic oil in the hydraulic oil chamber 13 back into the first recoil chamber 2 through the first recoil valve 8 and the second recoil valve 10, respectively. The hydraulic oil pushes the pull rod piston 5 forward, thereby pushing the gun barrel to return to its original position. The aforementioned recoil and return processes are repeated cyclically, enabling the artillery recoil device to operate continuously and meeting the requirements for recoil control during artillery firing.
