Description

Technical Field

[0001] This utility model relates to the field of air cannon technology, specifically a falling hammer air cannon launching device. Background Technology

[0002] The principle of an air cannon is based on gas dynamics. It is a method of generating vibration by using the instantaneous pressure generated by compressing air. It was originally invented by German scientists at the end of the 19th century and has since been widely used in hydraulic acoustics, military, and industrial manufacturing.

[0003] An air cannon can be divided into three steps: inflation, deflation, and replenishment. First, we need to use a gas injection device to compress and inject gas into the air cannon to increase its volume. Then, we can use a programmable control device to control the opening and closing of the gas inlet and outlet to regulate the gas flow, thereby creating different pressure fields. Finally, the air cannon must also have a replenishment system to compensate for the gas loss that occurs over time and to ensure that the air cannon can maintain a constant pressure.

[0004] Traditional air cannon launching devices have low kinetic energy, complex structure, and generally inconvenient firing angle adjustment. In actual use, when restricted by terrain, it is not easy to adjust to use in a vertical or horizontal direction, which hinders the normal operation of the air cannon and makes the device have certain limitations.

[0005] A falling hammer air gun launching device was proposed to address the problems mentioned above. Utility Model Content

The pump pipe is connected to the air inlet, and the air inlet is connected to the interior of the inner spherical shell.

[0011] A sliding cavity is provided between the outer spherical shell and the inner spherical shell. A horizontal air outlet is provided in the middle of the side of the inner spherical shell away from the air inlet. A vertical air outlet is provided in the middle of the bottom of the inner spherical shell. An adjustment block is connected inside the sliding cavity.

The bottom end of the sliding rod is fixedly connected to the top of the drop hammer, and the top end of the sliding rod passes through the acceleration tube and is fixedly connected to a mounting plate. A lifting ring is fixedly connected to the top of the mounting plate.

[0015] Preferably, a vertical plate is fixedly connected to the top center of the falling hammer, and a fixing rod is fixedly connected to the inner top surface of the acceleration tube. A vertical groove is opened inside the vertical plate, and the fixing rod is located inside the vertical groove. The fixing rod is slidably connected to the vertical groove.

[0019] Compared with the prior art, the beneficial effects of this utility model are: by setting an outer spherical shell 8, an inner spherical shell 9, an air inlet 10, a horizontal air outlet 12, a vertical air outlet 13, an adjusting block 14, a connecting pipe 15, a sliding groove 16, and a launching tube 17, it can be easily adjusted to vertical or horizontal launching, improving the flexibility of the device. The specific details are as follows:

[0020] 1. By setting up an outer spherical shell 8, an inner spherical shell 9, an air inlet 10, a horizontal air outlet 12, a vertical air outlet 13, an adjusting block 14, a connecting pipe 15, a sliding groove 16, and a launching tube 17, when the device is restricted by terrain, it needs to be adjusted from the horizontal direction to the vertical direction. By loosening the bolts on the horizontal fixing plate 29, the launching tube 17 is separated from the fixing plate 29. Then, the launching tube 17 is rotated, which drives the connecting pipe 15 and the adjusting block 14 to rotate. The adjusting block 14 rotates inside the sliding cavity 11, so that the connecting pipe 15 is rotated to the position of the vertical air outlet 13. Then, the launching tube 17 is fixed by the longitudinal fixing plate 29, which can easily adjust to vertical firing. This improves the flexibility of the device and solves the problem that the firing angle of traditional air cannon launching devices is generally not easy to adjust during use. In specific use, when restricted by terrain, it is not easy to adjust to the vertical or horizontal direction, which hinders the normal operation of the air cannon.

[0021] 2. The device is equipped with a drop hammer 2, a connecting rod 3, a piston 5, a first strength membrane 6, a second strength membrane 7, a sliding rod 20, a mounting plate 25, and a lifting ring 26. In use, an external hoisting device serves as the power source. After being fixed to the hook by the lifting ring 26, the hoisting device is activated to pull the lifting ring 26 and the mounting plate 25 upwards. The mounting plate 25 then drives the sliding rod 20 and the drop hammer 2 upwards. The drop hammer 2 drives the connecting rod 3 and the piston 5 upwards. The drop hammer 2 causes the vertical plate 21 to press against the fixing rod 23, causing the fixing rod 23 to contract under pressure. After reaching a certain height, the hoisting tension is released. At this point, the weight of the drop hammer 2 itself causes it to press down, which in turn drives the piston 5 and the connecting rod 3 downwards. The elastic force of the spring 24 assists in the downward pressure. Using the hoisting device as the power source facilitates the use of the larger drop hammer 2, thus improving the device's applicability.

[0022] 3. It is equipped with a vertical plate 21, a vertical groove 22, a fixing rod 23, an auxiliary groove 27 and an auxiliary block 28. When the drop hammer 2 slides, the fixing rod 23 slides inside the vertical groove 22, which assists the drop hammer 2 in sliding. At the same time, when the drop hammer 2 slides, the symmetrically arranged auxiliary block 27 slides inside the auxiliary groove 28, which can assist in limiting the drop hammer 2 and further assist the smooth sliding of the drop hammer 2.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 The present invention provides a technical solution: a falling hammer air cannon launching device, including an acceleration tube 1, a projectile 18 and a falling hammer 2 slidably connected inside the acceleration tube 1, with a connecting rod 3 fixedly connected to the bottom of the falling hammer 2.

[0031] The bottom of the acceleration tube 1 is fixedly connected to the pump tube 4, the bottom of the connecting rod 3 is fixedly connected to the piston 5, the piston 5 is slidably connected to the pump tube 4, the middle of the inner wall of the pump tube 4 is provided with a first strength membrane 6, the bottom of the inner side of the pump tube 4 is provided with a second strength membrane 7, and the bottom of the pump tube 4 is connected to the outer spherical shell 8.

[0032] An inner spherical shell 9 is fixedly connected to the inner side of the outer spherical shell 8. An air inlet 10 is provided on the side of the outer spherical shell 8 near the second strength membrane 7. The pump pipe 4 is connected to the air inlet 10, and the air inlet 10 is connected to the interior of the inner spherical shell 9.

[0033] A sliding cavity 11 is provided between the outer spherical shell 8 and the inner spherical shell 9. A horizontal air outlet 12 is provided in the middle of the side of the inner spherical shell 9 away from the air inlet 10. A vertical air outlet 13 is provided in the middle of the bottom of the inner spherical shell 9. An adjusting block 14 is connected inside the sliding cavity 11.

[0034] The adjusting block 14 is slidably connected to the sliding cavity 11, and a connecting pipe 15 is connected through the middle of the adjusting block 14. A sliding groove 16 is opened on the outer side of the outer spherical shell 8 away from the air inlet 10, and the connecting pipe 15 is slidably connected to the sliding groove 16.

[0035] When the device is restricted by terrain, it needs to be adjusted from horizontal to vertical. This is done by loosening the bolts on the horizontal fixing plate 29 to separate the launch tube 17 from the fixing plate 29, and then rotating the launch tube 17. The launch tube 17 drives the connecting tube 15 and the adjusting block 14 to rotate. The adjusting block 14 rotates inside the sliding cavity 11, causing the connecting tube 15 to rotate to the position of the vertical air outlet 13. Then, the launch tube 17 is fixed by the longitudinal fixing plate 29, which can easily adjust it to vertical launch and improve the flexibility of the device.

[0036] A transmitting tube 17 is installed on the side of the connecting tube 15 away from the outer spherical shell 8. The inside of the connecting tube 15 is connected to the transmitting tube 17. A sealing cap 19 is snapped onto the outside of the transmitting tube 17 away from the connecting tube 15.

[0037] The top of the accelerator tube 1 is slidably connected to a slide rod 20. There are two slide rods 20 symmetrically arranged. The bottom end of the slide rod 20 is fixedly connected to the top of the drop hammer 2. A vertical plate 21 is fixedly connected to the middle of the top of the drop hammer 2.

[0038] A fixing rod 23 is fixedly connected to the middle of the inner top surface of the acceleration tube 1. A vertical groove 22 is opened inside the vertical plate 21. The fixing rod 23 is located inside the vertical groove 22 and is slidably connected to the vertical groove 22. When the drop hammer 2 slides, the fixing rod 23 slides inside the vertical groove 22, which plays an auxiliary role in the sliding of the drop hammer 2.

[0039] A spring 24 is slidably connected to the outside of the fixed rod 23. The top end of the spring 24 is fixedly connected to the acceleration tube 1, and the bottom end of the spring 24 is fixedly connected to the top of the vertical plate 21. The top end of the slide rod 20 passes through the acceleration tube 1 and is fixedly connected to the mounting plate 25. The top of the mounting plate 25 is fixedly connected to the lifting ring 26.

[0040] When the device is in use, it uses an external hoisting device as a power source. After being fixed to the hook by the hoisting ring 26, the hoisting device is started to pull the hoisting ring 26 and the mounting plate 25 to rise. The mounting plate 25 drives the sliding rod 20 and the drop hammer 2 to rise. The drop hammer 2 drives the connecting rod 3 and the piston 5 to rise. The drop hammer 2 drives the vertical plate 21 to press the fixed rod 23, and the fixed rod 23 contracts under force.

[0041] After reaching a certain height, the hoisting tension is released. At this time, the weight of the drop hammer 2 itself causes it to press down, which in turn causes the piston 5 and connecting rod 3 to press down. The elastic force of the spring 24 plays an auxiliary role in pressing down. By using the hoisting device as a power source, it is easy to handle the use of the larger weight drop hammer 2, thus improving the applicability of the device.

[0042] The accelerator tube 1 has symmetrical auxiliary grooves 27 on both sides inside. The drop hammer 2 has symmetrical auxiliary blocks 28 fixed on both sides. The auxiliary blocks 28 are slidably connected to the auxiliary grooves 27. When the drop hammer 2 slides, the symmetrically arranged auxiliary blocks 27 slide inside the auxiliary grooves 28, which can assist in limiting the drop hammer 2 and further assist the smooth sliding of the drop hammer 2.

[0043] A fixing plate 29 is horizontally fixed to the side of the outer spherical shell 8 away from the pump tube 4, and a fixing plate 29 is vertically fixed to the bottom side of the outer spherical shell 8. The fixing plate 29 is used to fix the position of the launching tube 17.

[0044] Working principle:

[0045] Before using this falling hammer air cannon launcher, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 5 As shown, when the device is in use, an external hoisting device is used as the power source. After being fixed to the hook by the hoisting ring 26, the hoisting device is started to pull the hoisting ring 26 and the mounting plate 25 to rise. The mounting plate 25 drives the sliding rod 20 and the drop hammer 2 to rise. The drop hammer 2 drives the connecting rod 3 and the piston 5 to rise. The drop hammer 2 drives the vertical plate 21 to squeeze the fixed rod 23. The fixed rod 23 is compressed under force. After rising to a certain height, the hoisting tension is released.

[0046] At this time, the weight of the drop hammer 2 itself causes it to press down, which in turn causes the piston 5 and connecting rod 3 to press down. The elastic force of the spring 24 plays an auxiliary role in pressing down, which compresses the air in the pump pipe 4. Under the action of air pressure, the first strength membrane 6 ruptures, and the piston 5 continues to slide, which causes the second strength membrane 7 to rupture as well. This generates air pressure inside the inner spherical shell 9. The air pressure reaches the inside of the launching tube 17 through the connecting pipe 15, which causes the projectile 18 to be launched from the launching tube 17, thus realizing the operation of the device.

[0047] When the device is restricted by terrain, it needs to be adjusted from horizontal to vertical. This is done by loosening the bolts on the horizontal fixing plate 29 to separate the launch tube 17 from the fixing plate 29, and then rotating the launch tube 17. The launch tube 17 drives the connecting tube 15 and the adjusting block 14 to rotate. The adjusting block 14 rotates inside the sliding cavity 11, causing the connecting tube 15 to rotate to the position of the vertical air outlet 13. Then, the launch tube 17 is fixed by the longitudinal fixing plate 29, which can easily adjust it to vertical launch and improve the flexibility of the device.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
