Description

Technical Field

[0001] The invention relates to the technical field of a launching cradle, in particular to a launching cradle for a lifeboat. Background Art

[0002] A lifeboat is a special lifeboat installed on a ship for rescuing passengers in the event of a shipwreck. It is propelled by paddling, sails, and power engines. An air box is often installed in the boat so that the boat still has sufficient buoyancy after taking on water to ensure the safety of the boat and the people on board. The lifeboat of a seagoing ship is also equipped with a certain amount of fresh water, food, and daily necessities. Lifeboats can usually be divided into three categories according to their structure: open lifeboats, partially enclosed lifeboats, and fully enclosed lifeboats. They can also be divided into three categories according to their materials: galvanized steel boats, aluminum alloy boats, and fiberglass boats. Among them, fiberglass boats are made of glass fiber woven into cloth and then bonded to the inside of the structure with resin glue. Fiberglass boats have the advantages of light weight, high strength, durability, and no corrosion from seawater. They are widely used and are currently the most commonly used lifeboats.

[0003] Chinese patent CN221519957U discloses a lifeboat launching bracket with high safety performance, comprising: a lifeboat hull, four groups of running structures are installed on the lower wall of the lifeboat hull, two groups of track structures are movably installed inside the four groups of running structures, fixed structures are installed on the side walls of the two groups of track structures, and a pull rope structure is installed between the fixed structure and the track structure, and eight groups of seat structures are installed inside the lifeboat hull; the four groups of running structures include: two running frames, two running shafts and two running wheels; the two running frames are respectively installed on the lower wall of the lifeboat hull, and the two running shafts are respectively installed between the two running frames; when the utility model lowers the lifeboat, it does not need to rely on external energy, so when an accident occurs in the mother ship and the power is cut off, the lifeboat can still be lowered, and the crew can be guaranteed to escape safely and quickly.

[0035] A pushing component is provided on the side of the lifeboat 25 close to the mother ship, and the pushing component includes an ear block 26 and a hydraulic rod 27. The ear block 26 is provided in two groups, each group is provided with two pieces, and the two groups of ear blocks 26 are respectively fixedly installed on the outer walls of the left and right ends of the lifeboat 25. There are two hydraulic rods 27, one end of the hydraulic rod 27 is inserted between the two ear blocks 26 and is rotatably connected through a circular shaft, and a circular plate 28 is fixedly installed on the other end of the hydraulic rod 27.

The push plate 2 36 is slidably sleeved on the outer end of the support track 2 through the sliding hole 37. A damper 2 38 is fixedly installed between the push plate 2 36 and the fixed plate 1. The outer end of the damper 2 38 is sleeved with a spring 4 39. One end of the spring 4 39 is fixedly installed on the outer wall of the fixed plate 1, and the other end is fixedly installed on the outer wall of the push plate 2 36. The side of the support track 2 close to the lower slide track 10 is connected with a U-shaped block 14 through a clamping component. The inner walls of the left and right ends of the U-shaped block 14 are slidably sleeved on the outer wall of the support track 2. One end of the U-shaped block 14 is fixedly installed with a damper 15. The damper 11 5 is fixedly mounted with a push plate 16 at the outer end, and the push plate 16 is slidably connected to the upper end of the support track 2. The outer end of the damper 15 is sleeved with a spring 17, one end of the spring 17 is fixedly mounted on the outer wall of the U-shaped block 14, and the other end of the spring 17 is fixedly mounted on the outer wall of the push plate 16. The two sliders 24 on the same side of the lifeboat 25 are respectively located between the push plate 16 and the push plate 2 36, and the spring 17 and the spring 4 39 are both in a compressed state, limiting the slider 24 and the lifeboat 25. When the lifeboat 25 slides, the spring 17 and the damper 15 or the spring 4 39 and the damper 2 38 are squeezed or stretched, thereby starting the buffering effect on the lifeboat 25.

[0037] A plurality of reinforcing rods 33 are evenly and fixedly installed between the descending tracks 10. The reinforcing rods 33 play the role of reinforcing the descending tracks 10 and can also be used as a ladder, so that the personnel on the boat mother can climb up the supporting track 2 through the ladder 4 and then enter the lifeboat 25 that has fallen into the water through the reinforcing rods 33 between the descending tracks 10. When the descending track 10 is erected, a safety rope 35 is fixedly connected between the reinforcing rod 33 and the ladder 4 to fix the descending track 10. When escaping, the personnel go down into the lifeboat 25 and cut the safety rope 35 by the hydraulic clamps placed in the lifeboat 25 in advance. Under the gravity of the descending track 10, the descending track 10 automatically falls.

[0038] The card-connecting components include an inserting slot 7, a groove 8, a push block 13 and a fixed block 18. The inserting slot 7 is arranged on the left and right sides of the connecting slot 6, the groove 8 is arranged on the upper side of the outer end of the supporting rail 2, and the inserting slot 7 is connected to the groove 8. The inner end of the inserting slot 7 is arranged with a limiting slot 34, and the limiting slot 34 is also connected to the groove 8.

A limit block 21 is slidably inserted into the slide groove 20, and a spring 22 is fixedly installed between the inner end of the limit block 21 and the inner end of the slide groove 20. A guide slope is provided at the lower side of the outer end of the limit block 21. When the fixed block 18 is slidably inserted into the groove 8, the clearance groove 19 is located on the inner side of the limit groove 34, and the limit block 21 is inserted into the limit groove 34 by squeezing the spring 22. At the same time, the U-shaped block 14 is clamped at the upper end of the support rail 2. The compression spring three 23 is in a compressed state, thereby fixing the U-shaped block 14 to the upper end of the support track 2. When escaping, when the downward slide track 10 is lowered, the movable plate 12 rotates into the connecting groove 6, and at the same time, the push block 13 is inserted into the plug-in groove 7 and the limit groove 34 and contacts the guide slope at the lower end of the limit block 21. The limit block 21 is pushed out of the limit groove 34 by squeezing the spring two 22. At the same time, the escaping personnel slide the lifeboat 25. When the lifeboat 25 moves toward one side of the push plate one 16, the U-shaped block 14 is pushed out of the outer end of the support track 2 under the action of the rebound force of the spring three 23, and the lifeboat 25 can slide down from the support track 2 and the downward slide track 10.

[0040] When the device is working, the lifeboat 25 is fixed on the support track 2, and the two sliders 24 on the same side of the lifeboat 25 are respectively located between the push plate 16 and the push plate 2 36, and the spring 17 and the spring 4 39 are both in a compressed state, so that the slider 24 and the lifeboat 25 are limited. When the lifeboat 25 slides, the spring 17 and the damper 15 or the spring 4 39 and the damper 2 38 are squeezed or stretched, and the buffering effect on the lifeboat 25 is started. When escaping is needed, the personnel quickly climb into the lifeboat 25 fixed at the upper end of the support track 2 through the ladder 4. , cut the safety rope 35 through the hydraulic pliers, lower the descending track 10, and push the reaction force generated by the mother boat to slide the lifeboat 25 into the water. If the mother boat tilts and the lifeboat 25 cannot be pushed by manpower, the hydraulic rod 27 is pulled out of the elastic clamp 29, and then the hydraulic rod 27 is rotated so that the end with the circular plate 28 faces the side of the mother boat, and then the hydraulic handle of the hydraulic rod 27 is driven back and forth quickly. The output end of the hydraulic rod 27 pushes the circular plate 28 toward the mother boat, and the lifeboat 25 is pushed into the water under the reaction force of the hydraulic rod 27, which is convenient for rapid escape.
