Description

Technical Field

[0001] This utility model relates to the field of projectile technology, and in particular to a marine rescue projectile device. Background Technology

[0002] A rescue thrower is a key piece of equipment used for maritime distress rescue. It can quickly project rescue supplies such as lifebuoys and ropes to the target location using compressed air or gunpowder power, and is widely used in ships, offshore oil platforms and other locations.

[0003] Traditional launchers rely on handheld operation, which is extremely unstable. However, in a maritime environment, platforms are often subject to swaying due to wind and waves, making it difficult for operators to maintain a stable posture when using a handheld launcher. This results in difficulty in precisely controlling the launching angle and force. This not only reduces the accuracy of rescue supplies but also poses safety hazards to the operators themselves due to unstable operation, seriously hindering the smooth progress of rescue operations.

[0004] Existing launchers are equipped with supports to improve operational stability. However, these supports are mostly flat structures placed on the platform surface with very low foundations. In locations like oil platforms with fencing, these supports are easily obstructed by fences, equipment, and other objects on the platform. This not only hinders the launcher's trajectory, preventing the successful delivery of rescue supplies, but also may cause deviations in the launch direction due to obstructions, increasing the uncertainty and difficulty of the rescue operation.

[0005] Therefore, we propose a marine rescue projectile device. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a marine rescue projectile device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a marine rescue launching device, comprising a counterweight base and a launcher, wherein a column is fixedly connected to the top of the counterweight base, and a movable frame is provided on the top and side of the column, and a height adjustment component is installed between the movable frame and the column.

[0008] The inner walls on both sides of the movable frame are rotatably connected to a screw-type telescopic component. A rotating component is fixedly installed on the movable end of the screw-type telescopic component. A support sleeve is fixedly connected to the movable end of the rotating component. A support plate is rotatably connected to both sides of the outer surface of the support sleeve, and the support plate is fixedly installed on the top of the movable frame.

[0009] The gas cylinder end of the thrower is inserted into the support sleeve. The top of the support sleeve is provided with a hand-tightening bolt that extends into the interior, and the hand-tightening bolt is threadedly connected to the thrower.

[0010] Furthermore, the outer surface of the launcher is pre-drilled with threaded holes, and the hand-tightening bolts match the threaded holes. This design allows the launcher to be quickly installed and disassembled, while ensuring that it remains stable and does not loosen during launch.

[0011] Furthermore, the height adjustment assembly includes a first bearing housing, and a movable frame is fixedly sleeved on the outer surface of the first bearing housing. The inner ring of the bearing housing is fixedly connected to a first screw, and a first nut is threaded onto the outer surface of the first screw. The column is fixedly sleeved on the outer surface of the first nut. This structure achieves smooth lifting and lowering through screw and nut transmission.

[0012] Furthermore, a first handwheel is fixedly connected to the top of the first screw, which facilitates manual driving of the first screw to rotate.

[0013] Furthermore, the screw-type telescopic component includes a connecting block, which is rotatably connected to the inner walls on both sides of the movable frame. A hollow tube is fixedly connected to the top of the connecting block, and a second nut is fixedly embedded in the top of the hollow tube. A second screw is threadedly connected to the inner surface of the second nut, and a second handwheel is fixedly sleeved on the outer surface of the second screw. The second handwheel facilitates manual driving of the second screw to rotate.

[0014] Furthermore, the rotating component includes a connecting rod, which is fixedly installed on the top of the second screw, and the connecting rod serves as the connection base between the rotating component and the screw-type telescopic component.

[0015] Furthermore, the rotating component also includes an assembly block, which is fixedly connected to the support sleeve. The two assembly blocks are rotatably connected to a second bearing seat. The inner ring of the bearing built into the second bearing seat is fixedly sleeved on the outer surface of the connecting rod. The second bearing seat can reduce the rotational resistance of the connecting rod.

[0016] The beneficial effects of this utility model are:

[0017] 1. In use, this utility model effectively solves the technical problem of obstructed launch paths in environments with obstacles such as fences by using a combination of a counterweight base and a height-adjustable movable frame. This structure allows the launcher to flexibly adjust its operating height, either lowering it to a conventional operating position or raising it to a launch position above obstacles, significantly improving its adaptability to rescue operations in complex maritime environments and providing a reliable guarantee for the smooth deployment of rescue supplies.

[0018] 2. This utility model employs a multi-directional adjustable mechanical structure design, fundamentally overcoming the technical defects of poor stability in handheld operation. Through the synergistic effect of the column support structure and the screw-type telescopic component, the height and angle of the launcher are stably adjusted, enabling operators to maintain the stability of the launching trajectory in a maritime platform environment, significantly improving the safety and reliability of maritime rescue operations.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-4As shown, a marine rescue launching device is disclosed, comprising a counterweight base 1 and a launcher 4. A column 2 is fixedly connected to the top of the counterweight base 1. A movable frame 9 is provided on the top and side of the column 2. The outer wall of the movable frame 9 slides against the outer wall of the column 2 to ensure stable movement of the movable frame 9. A height adjustment component is installed between the movable frame 9 and the column 2. The height adjustment component includes a first bearing seat 11, and the movable frame 9 is fixedly sleeved on the outer surface of the first bearing seat 11. A first screw 13 is fixedly connected to the inner ring of the bearing inside the first bearing seat 11. A first nut 12 is threaded onto the outer surface of the first screw 13, and the column 2 is fixedly sleeved on the outer surface of the first nut 12. A first handwheel 8 is fixedly connected to the top of the first screw 13. The thread helix angle of the first screw 13 is smaller than the friction angle, which enables the first screw 13 to have a self-locking capability and prevent it from shifting due to vibration or load.

[0028] The inner walls on both sides of the movable frame 9 are rotatably connected to a screw-type telescopic component. The screw-type telescopic component includes a connecting block 10, which is rotatably connected to the inner walls on both sides of the movable frame 9. A hollow tube 3 is fixedly connected to the top of the connecting block 10, and a second nut 17 is fixedly embedded in the top of the hollow tube 3. A second screw 16 is threadedly connected to the inner surface of the second nut 17, and a second handwheel 19 is fixedly sleeved on the outer surface of the second screw 16. The thread helix angle of the second screw 16 is smaller than the friction angle, which gives the second screw 16 a self-locking ability and can prevent it from shifting on its own due to vibration or load.

[0029] A rotating component is fixedly installed on the movable end of the screw-type telescopic component. A support sleeve 6 is fixedly connected to the movable end of the rotating component. The rotating component includes a connecting rod 15, which is fixedly installed on the top of the second screw 16. The rotating component also includes an assembly block 18, which is fixedly connected to the support sleeve 6. The two assembly blocks 18 are rotatably connected to a second bearing seat 14. The inner ring of the bearing inside the second bearing seat 14 is fixedly sleeved on the outer surface of the connecting rod 15. Support plates 7 are rotatably connected to both sides of the outer surface of the support sleeve 6, and the support plates 7 are fixedly installed on the top of the movable frame 9. The support plates 7 provide support for the support sleeve 6 and are the center point for adjusting the angle of the support sleeve 6.

[0030] The gas cylinder end of the thrower 4 is inserted into the support sleeve 6. The top of the support sleeve 6 is provided with a hand-tightening bolt 5 that extends into the interior. The hand-tightening bolt 5 is threadedly connected to the thrower 4. The outer surface of the thrower 4 has a pre-set threaded hole, and the hand-tightening bolt 5 matches the threaded hole. The hand-tightening bolt 5 and the threaded hole cooperate to fix the thrower 4 and the support sleeve 6.

[0031] Working principle: The counterweight base 1 provides stable support for the entire device through its own weight, and the column 2 is vertically fixed to the top of the counterweight base 1 as the main support structure. The movable frame 9 is connected to the column 2 through the first bearing seat 11. When the operator rotates the first handwheel 8, it drives the first screw 13 to rotate, and through the threaded first nut 12, it drives the movable frame 9 to move up and down along the column 2, thereby adjusting the overall height of the movable frame 9.

[0032] The screw-type telescopic component is rotatably connected to the movable frame 9 via the connecting block 10. A second nut 17 is provided inside the hollow tube 3. When the second handwheel 19 is rotated, the second screw 16 is driven to spirally rise and fall within the second nut 17, realizing telescopic movement. The connecting rod 15 at the top of the second screw 16 is connected to the support sleeve 6 via the second bearing seat 14, so that the support sleeve 6 swings around the rotational connection point between the support sleeve 6 and the support plate 7, thereby adjusting the launching angle of the thrower 4.

[0033] The gas cylinder end of the thrower 4 is inserted into the support sleeve 6 and locked in place by the hand-tightening bolt 5. In use, the operator first adjusts the first handwheel 8 to bring the thrower 4 to a suitable height, then adjusts the telescopic length using the second handwheel 19, and adjusts the launching angle using the support sleeve 6, ultimately ensuring that the thrower 4 launches rescue supplies at the optimal angle and position.

[0034] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
