Embodiment 1
[0014] Such as figure 1 As shown, a multi-stage gas cannon anti-recoil device includes: cylinder body I1, cylinder body II3, buffer rod 5, gas injection valve 6, balance valve 7;
[0015] Cylinder Ⅰ1 is fixedly connected with the gun body, as the retention basis of the whole device, there is no relative movement with the gun body during the firing process of the gas cannon; cylinder Ⅱ3 is fixedly installed on the cylinder Ⅰ1, and the cylinder Ⅰ1 is divided into two airtight chambers One end of the buffer rod 5 is movably connected with the cylinder body II3, and the cylinder body II3 is divided into two airtight chambers; Pressure gas, each chamber is connected through the balance valve, and the pressure of each chamber is adjusted through the balance valve 7 at different stages during the firing process of the gas cannon, so as to realize the buffering of recoil and forward momentum.
Embodiment 2
[0017] Such as figure 2 As shown, a multi-stage air cannon anti-recoil device consists of cylinder body I1, cover plate 2, cylinder body II3, fixed seat 4, buffer rod 5, gas injection valve 6, balance valve 7, gas injection valve I8, balance valve Ⅰ9 composition;
[0018] (1) Cylinder block I1 is connected to the gun body (specifically, the barrel of the gas gun), and there is no relative movement with the gun body during the firing of the gas gun;
[0019] (2) The cover plate 2 is used as the connecting cover plate after the assembly of the cylinder body I1 and the cylinder body II3, so that a closed gas chamber is formed between the cylinder body I1 and the cylinder body II3; here, between the cover plate 2 and the cylinder body I1 It can be a separate structure, connected by a sealed connection, or an integrated structure connected by welding, or other structures thought of by those skilled in the art;
[0020] (3) Cylinder body II3, used to connect cylinder body I1 and ...

Abstract
The invention relates to a multi-stage gas cannon anti-recoil device, belonging to the technical field of mechanical processing; comprising: cylinder body I (1), cylinder body II (3), buffer rod (5), gas injection valve (6), balance valve (7); Cylinder body I is fixedly connected to the gun body, cylinder body II is fixedly connected to cylinder body I, one end of the buffer rod is movably connected to cylinder body II, and the other end is connected to the gun body. The body II chambers are filled with gases of different pressures, and each chamber is connected through a balance valve. At different stages of the gas cannon firing process, the pressure of each chamber is adjusted through the balance valve to achieve buffering of recoil and forward momentum. Compared with the prior art, the present invention can accurately return to zero the displacement generated by different working conditions in a short period of time during the firing process of the air cannon, absorb the peak force generated by different force directions gently, and reduce the rigidity requirement and the bearing strength of the foundation; The structure is simple, and it replaces the combined working effect of multiple retreating machines and re-entrying machines of the original air cannon.
Description
technical field [0001] The invention relates to a multi-stage gas cannon anti-recoil device, which belongs to the technical field of gas cannon anti-recoil devices. Background technique [0002] The recoil force and forward momentum generated by the gas guns of two or more levels (abbreviated as multi-stage gas guns) during the firing process are too large to cause damage to the gun body itself and the foundation. The existing anti-recoil structure uses a combination of multiple parking machines and re-entry machines to reduce the impact force of the recoil. The structure is complex, and the anti-recoil resistance is adjusted through fluid holes of different sizes. The buffer function fails, destroying the gun body and foundation. The forward momentum that occurs at different stages of the firing process can only be absorbed by the gun body, which affects the rigidity of the gun body. Contents of the invention [0003] The purpose of the present invention is to overcome t...
