Description

Technical Field

[0001] This utility model relates to the field of underwater engineering equipment technology, and in particular to a positioning ring for a diving cage. Background Technology

[0002] A diving cage is a closed or semi-closed structure made of a metal frame, mainly used to carry divers, underwater tools or materials, and to transport them between the underwater and surface via lifting equipment. It is widely used in underwater engineering, marine exploration, underwater rescue and other scenarios, providing a safe carrying and transfer space for underwater operations. The positioning ring for the diving cage is a ring-shaped component installed on the diving cage, usually set at the top edge or side of the cage for easy connection. Its core function is to work with the lifting rope (or steel cable). When the lifting rope passes through the middle of the positioning ring, the ring can constrain the sway of the lifting rope, thereby reducing the large swing of the diving cage during lifting, descent, underwater operation or ascent, ensuring the safety and accuracy of underwater operations.

[0003] In actual operation of diving cages, the positioning rings installed on the sides are key components to ensure the stable operation of the cage. However, the inner diameter of existing positioning rings is mostly fixed, which can only be used with specific diameter lifting ropes or steel cables. When it is necessary to change to different specifications of lifting ropes in the operation (such as adjusting the rope diameter due to load-bearing requirements), the fixed-size positioning rings cannot effectively cooperate with the new lifting ropes. If the diameter of the lifting rope is smaller than the inner diameter of the positioning ring, a large gap will be generated between the two, and the lifting rope will easily sway inside the ring, which will weaken the restraining effect of the positioning ring on the cage. This will make the cage prone to large swings during water flow impact or hoisting. If the diameter of the lifting rope is larger than the inner diameter of the positioning ring, it cannot be smoothly inserted, and the entire positioning ring must be replaced. This not only increases equipment costs but also prolongs the preparation time for operation and reduces the efficiency and flexibility of underwater operations. In addition, when the fixed-size positioning ring contacts the lifting rope, it is often a rigid contact. Long-term use can easily lead to accelerated wear of the lifting rope due to friction, which poses a safety hazard.

[0004] Therefore, this application provides a positioning ring for a diving cage. Utility Model Content

[0005] This utility model provides a positioning ring for a diving cage to solve the problem that existing positioning rings are difficult to adapt to different diameter suspension ropes or steel cables due to their fixed size. Specifically, it can solve the problem of poor positioning stability and easy swinging of the cage caused by the suspension rope swaying inside the ring when the diameter of the suspension rope does not match the inner diameter of the positioning ring.

[0006] This utility model provides a positioning ring for a diving cage, including a diving cage and positioning rings. Multiple positioning rings are symmetrically fixedly installed on the left and right sides of the diving cage, and each of the multiple positioning rings is provided with a connecting limiting component inside.

[0007] The connecting and limiting assembly includes a fixed cylinder, a connecting moving rod, a roller bracket, a limiting roller, a connecting plate, and a return spring. Multiple fixed cylinders are fixedly installed through the inner wall of the positioning ring, and a connecting moving rod is movably installed through the middle of each of the multiple fixed cylinders. A roller bracket is fixedly installed at one end of each of the multiple connecting moving rods that is close to each other. Two limiting rollers are rotatably connected inside the roller bracket. A connecting plate is fixedly installed on the outer surface of the end of the connecting moving rod away from the roller bracket. A return spring is fixedly installed on one side of the connecting plate, and the end of the return spring away from the connecting plate is in contact with the inner wall of the positioning ring.

[0008] In a positioning ring for a diving cage according to one embodiment of the present invention, a cage top plate is fixedly installed on the top surface of the diving cage, and a main connecting ring is fixedly installed on the top surface of the cage top plate near the middle.

[0009] In a positioning ring for a diving cage according to one embodiment of the present invention, a reinforcing support plate is fixedly installed on the top and bottom surfaces of the positioning ring, and the reinforcing support plate is fixed to the side of the diving cage by bolts.

[0010] In a positioning ring for a diving cage according to one embodiment of the present invention, the outer surface of the limiting roller is provided with a wear-resistant layer, which can be made of high molecular weight polyethylene material.

[0011] In a positioning ring for a diving cage according to one embodiment of the present invention, a plurality of protective partitions are fixedly installed on the inner side wall of the diving cage, and a plurality of water-permeable holes are evenly spaced on one side of the plurality of protective partitions.

[0012] In a positioning ring for a diving cage according to one embodiment of the present invention, a plurality of reinforcing connecting rods are symmetrically fixedly installed on the side of the top plate of the cage, and the ends of the plurality of reinforcing connecting rods away from the top plate of the cage are all fixed to the top surface of the diving cage.

[0013] In a positioning ring for a diving cage according to one embodiment of the present invention, multiple auxiliary lifting rings are fixedly installed on the top surface of the cage top plate near the corners.

[0014] The technical solution provided in this application embodiment can include the following beneficial effects: This application designs a positioning ring for a diving cage. When the sling or steel cable passes through the positioning ring, it will contact and squeeze the inner limiting roller. At this time, the connecting moving rod slides outward in the fixed cylinder, driving the connecting plate to compress the return spring. The reaction force of the return spring is transmitted to the roller bracket through the connecting plate and the connecting moving rod, so that the limiting roller is tightly attached to the surface of the sling, forming an adaptive clamping, which can effectively adapt to slings of different diameters. The return spring can adjust the clamping force through different degrees of extension and retraction to ensure that the limiting roller is always in effective contact with the sling, avoiding sling sway. This positioning ring can effectively achieve adaptive positioning for slings of different specifications, improving the stability and safety of the diving cage in complex underwater environments.

[0023] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] like Figures 1 to 4 As shown, this application provides a positioning ring for a diving cage, comprising:

[0025] A positioning ring for a diving cage includes a diving cage 1 and a positioning ring 2. A cage top plate 4 is fixedly installed on the top surface of the diving cage 1. A main connecting ring 5 is fixedly installed near the center of the top surface of the cage top plate 4. Multiple auxiliary rings 10 are fixedly installed near the corners of the top surface of the cage top plate 4. Multiple reinforcing connecting rods 9 are symmetrically fixedly installed on the sides of the cage top plate 4, and the ends of the multiple reinforcing connecting rods 9 away from the cage top plate 4 are all fixed to the top surface of the diving cage 1. The main connecting ring 5 can be connected to the lifting equipment on the hull, thus serving as the main lifting point and ensuring the overall force balance of the cage. The auxiliary rings 10 can assist in lifting under special working conditions, improving lifting flexibility. The reinforcing connecting rods 9 can enhance the connection strength between the cage top plate 4 and the diving cage 1, preventing structural deformation due to excessive force during lifting.

[0026] Multiple protective partitions 8 are fixedly installed on the inner wall of the diving cage 1, and multiple water-permeable holes are evenly spaced on one side of the multiple protective partitions 8. The protective partitions 8 can separate and protect the personnel or materials in the cage, reduce mutual collisions, and the water-permeable holes can balance the internal and external water pressure when the cage dives or floats, reduce the impact of water flow on the cage, and improve the stability of operation.

[0027] Multiple positioning rings 2 are symmetrically fixedly installed on the left and right sides of the diving cage 1, and each positioning ring 2 is equipped with a connecting limiting component 3. Reinforcing support plates 6 are fixedly installed on the top and bottom surfaces of the positioning rings 2, and the reinforcing support plates 6 are fixed to the sides of the diving cage 1 by bolts. The symmetrically distributed positioning rings 2 can constrain the hoisting rope from both sides, improving the overall positioning stability of the cage. The reinforcing support plates 6 can further strengthen the fixing effect between the positioning rings 2 and the diving cage 1 by bolt connection, preventing the positioning rings 2 from loosening and falling off when under force.

[0028] The connecting and limiting assembly 3 includes a fixed cylinder 301, a connecting moving rod 302, a roller bracket 303, limiting rollers 304, a connecting disc 305, and a return spring 306. Multiple fixed cylinders 301 are fixedly installed through the inner wall of the positioning ring 2, and a connecting moving rod 302 is movably installed through the middle of each of the multiple fixed cylinders 301. A roller bracket 303 is fixedly installed at one end of each connecting moving rod 302 that is close to the others. Two limiting rollers 304 are rotatably connected inside the roller bracket 303. The outer surface of the limiting rollers 304 is provided with a wear-resistant layer 7, which can be made of high molecular weight polyethylene. The fixed cylinder 301 provides a stable sliding channel for the connecting moving rod 302, ensuring smooth and unobstructed movement when the connecting moving rod 302 reciprocates within it. A sealing structure is also provided inside the fixed cylinder 301. It can effectively prevent external liquid from entering the interior of the positioning ring 2. The sealing structure can be made by setting an O-ring rubber seal at the gap between the fixed cylinder 301 and the connecting moving rod 302, and using the elasticity of the rubber to tightly fit the surfaces of the two to form a seal. Alternatively, a lip seal can be used, which has a lip-shaped cross section and can maintain a sealed state by its own elasticity when the connecting moving rod 302 moves. The limiting roller 304 will rotate with the movement of the lifting rope when it comes into contact with the lifting rope. The rolling of the limiting roller 304 can greatly reduce the frictional resistance between the two and avoid the wear caused by rigid sliding. The high molecular weight polyethylene wear-resistant layer 7 on the outer surface of the limiting roller 304 can make the roller surface smoother, reduce the coefficient of friction when in contact with the lifting rope, and reduce surface wear after long-term use through its excellent wear resistance, thus reducing the wear on the lifting rope.

[0029] A connecting plate 305 is fixedly installed on the outer surface of the end of the connecting moving rod 302 away from the roller bracket 303. A return spring 306 is fixedly installed on one side of the connecting plate 305. The end of the return spring 306 away from the connecting plate 305 is in contact with the inner wall of the positioning ring 2. The connecting plate 305 can effectively transmit the elastic force of the return spring 306. When the lifting rope is inserted, the return spring 306 can drive the connecting moving rod 302 and the limiting roller 304 to adaptively adjust their positions through extension and retraction, so that the limiting roller 304 is always tightly attached to the lifting rope of different diameters, realizing stable clamping of the lifting rope and improving the adaptability of the positioning ring 2 to lifting ropes of different specifications.

[0030] The diving cage uses a positioning ring; when the hoisting rope (or steel cable) passes through the positioning ring 2, the hoisting rope will contact the inner limiting roller 304 and be squeezed. At this time, the connecting moving rod 302 slides outward in the fixed cylinder 301, driving the connecting plate 305 to compress the return spring 306. The reaction force of the return spring 306 is transmitted to the roller bracket 303 through the connecting plate 305 and the connecting moving rod 302, so that the limiting roller 304 is tightly attached to the surface of the hoisting rope, forming an adaptive clamping, which can effectively adapt to hoisting ropes of different diameters. The return spring 306 can adjust the clamping force through different degrees of extension and retraction to ensure that the limiting roller 304 is always in effective contact with the hoisting rope and to prevent the hoisting rope from swaying.

[0031] During hoisting or underwater operations, the positioning ring 2 is securely connected to the diving cage 1 via the reinforcing support plate 6. The symmetrically distributed positioning rings 2 on both sides, together with the clamping action of the limiting rollers 304, constrain the swing space of the hoisting rope laterally. The main connecting ring 5 and the auxiliary ring 10 on the top plate 4 of the cage ensure balanced hoisting force. The reinforcing connecting rod 9 enhances the strength of the top structure. At the same time, the wear-resistant layer 7 outside the limiting rollers 304 reduces friction loss. This device can effectively achieve adaptability positioning for hoisting ropes of different specifications, improving the stability and safety of the diving cage in complex underwater environments.
