Description

Technical Field

[0001] This utility model relates to the field of ship platform structure strength verification technology, and in particular to a tooling for ship platform structure strength verification. Background Technology

[0002] The strength verification of the hull platform structure is a core part of the ship design, construction and operation and maintenance stages. Its purpose is to ensure that the platform structure does not suffer from strength failure, excessive deformation or fatigue failure under various expected loads, so as to ensure the safety of ship navigation and service life. During this process, a scaled-down model of the hull is typically positioned on a structural strength verification fixture on the hull platform for strength verification. If the hull is not properly designed and results in insufficient stability, the hull may break. In the test, the hull and the fixture platform are subjected to strong shaking due to simulated wind, waves, and impacts. Therefore, broken parts are prone to flying out, causing damage to electronic equipment and injuries to personnel. To address this, protective structures are provided. Currently, most protective structures use materials such as steel plates and tempered glass as interceptors. These relatively hard materials rely on their own rigidity to directly block broken parts, which can easily cause parts to bounce back rigidly, creating a secondary flying hazard. Additionally, the interceptors themselves may break or shatter upon impact, generating new sources of debris hazards. Therefore, this application provides a tooling for verifying the structural strength of a ship platform to meet the requirements. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a tooling for verifying the structural strength of a ship platform, thereby solving the technical problem of secondary launch of ship parts, impact fracture and breakage of the interceptor itself, and the generation of new debris hazard sources.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A structural strength verification fixture for a ship platform includes a fixture body, a protective structure on the outside of the fixture body, a collection box, an annular water bladder in the collection box, and an annular plate connected to the surface of the annular water bladder. The outside of the collection box is provided with a support assembly; A water injection assembly is provided on one side of the tool body. The water injection assembly includes a water tank located in the collection box, a first water pump, and a second water pump. The input end of the first water pump is equipped with a first water pipe that communicates with the inside of the water tank, and the output end of the first water pump is equipped with a second water pipe that communicates with the annular water bladder. A water collection component is installed on the outside of the collection box.

[0005] By filling the annular water bladder inside the protective structure with water through the water injection component, the annular water bladder expands and bulges, making the annular water bladder stand on the outside of the tool body. This can achieve gradient dissipation of impact load and avoid secondary risks caused by broken parts bouncing back or intercepting parts breaking apart.

[0006] Optionally, the support assembly includes a support frame on which a hydraulic rod is mounted, and a connecting plate is mounted on the telescopic end of the hydraulic rod, the connecting plate being connected to an annular plate.

[0007] The support frame is used to support the hydraulic rod, and the hydraulic rod is also used to adjust the height of the top of the annular water bladder via the connecting plate, making it easy to stand the annular water bladder upright.

[0008] Optionally, a base plate is installed at the bottom of the support frame, and a positioning hole is provided through the base plate.

[0009] By setting positioning holes and using fasteners such as bolts, the base plate is fixed in a designated position to effectively support the hydraulic rod.

[0010] Optionally, the input end of the second water pump is equipped with a fourth water pipe that communicates with the inside of the annular water bladder, and the output end of the second water pump is equipped with a third water pipe that communicates with the inside of the water tank.

[0011] By setting up a fourth and third water pipe, and cooperating with a second water pump, after the hull strength test is completed, the water in the annular water bladder is pumped back into the water tank, causing the annular water bladder to deflate, thus utilizing the retraction of the annular water bladder.

[0012] Optionally, the water collection assembly includes an interception box with an annular groove, a cover plate placed on the annular groove, and multiple filter holes through the cover plate.

[0013] By designing the interception box, annular trough, cover plate, and multiple filter holes, if the annular water bladder ruptures, the water inside can be discharged into the interception box for collection, minimizing the risk of water flowing everywhere.

[0014] Optionally, a water pumping pipe is installed on the cover plate, and a threaded plug is connected to the internal thread of the water pumping pipe.

[0015] By installing a water pump pipe, the hose connected to the pump's pumping end can be inserted into the interception box, making it easier to pump out the water collected in the interception box. The presence of a threaded plug is also used to block the inside of the water pump pipe.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects: By setting up a protective structure and water injection components, the first water pump is started to fill the water tank into the annular water bladder, thereby causing the annular water bladder to expand and stand on the outside of the tool body. When the hull parts are launched, the elasticity of the annular water bladder and the water inside it will buffer the hull parts and minimize the secondary launch of the hull parts. If the annular water bladder is punctured by the hull parts, no new fragments or dangerous parts will be generated. By setting up a support component, while water is being filled into the annular water bladder, the hydraulic rod is activated, causing its telescopic end to pull up the top of the annular water bladder, thereby assisting in the standing of the annular water bladder and improving its stability. By setting up a water collection component, if the annular water bladder is punctured by a hull part, water will flow out from inside the annular water bladder. At this time, the water will enter the interception box through the filter holes for collection, thus minimizing water spillage. Attached Figure Description

[0026] The hull platform structure strength verification fixture provided in this embodiment of the invention aims to solve the problem of secondary ejection of hull parts, impact fracture and breakage of the interceptor components, and the generation of new debris hazard sources by providing the following technical solution. The hull platform structure strength verification fixture is composed of a protective structure, a water injection assembly, and other components. These components work together to minimize secondary ejection of hull parts and the generation of new debris hazard sources by the interceptor components.

[0027] like Figures 1-3 As shown, an embodiment of this utility model provides a hull platform structure strength verification fixture. The fixture includes a fixture body 5, a protective structure 1 on the outer side of the fixture body 5, a collection box 101, and an annular water bladder 102. The bottom surface of the annular water bladder 102 is connected to the inner bottom wall of the collection box 101, and an annular plate 103 is connected to the surface of the annular water bladder 102. A support assembly 2 is provided on the outer side of the collection box 101, and a water injection assembly 3 is provided on one side of the fixture body 5. The water injection assembly 3 includes a water tank 301 located in the collection box 101, a first water pump 302, and a second water pump 305. The water tank 301 is used to hold water, and the first water pump 302... The input end of the first pump 302 is equipped with a first water pipe 303 that is connected to the inside of the water tank 301, and the output end of the first pump 302 is equipped with a second water pipe 304 that is connected to the annular water bladder 102. According to the above technical solution, specifically, by starting the first pump 302, water is drawn out of the water tank 301 through the first water pipe 303, and then water is filled into the annular water bladder 102 through the second water pipe 304, thereby causing the annular water bladder 102 to expand and stand on the outside of the tool body 5. When the hull parts are launched, the elasticity of the annular water bladder 102 and the water inside it are used to buffer the hull parts, so as to avoid secondary launch of the hull parts. If the annular water bladder 102 is punctured by the hull parts, no new fragments or dangerous parts will be generated. It should be noted that the annular water bladder 102 is made of high-strength reinforced rubber composite material of model XC-HC-08 produced by Qingdao Xincheng Rubber Products Co., Ltd., with a thickness of 1000mm. In addition, a pit is dug in the ground, and the collection box 101 is located in the pit. When the annular plate 103 is attached to the top of the collection box 101, the top of the annular plate 103 should be level with the ground.

[0028] like Figure 2 As shown, the support assembly 2 includes a support frame 201, on which a hydraulic rod 204 is mounted. A connecting plate 205 is mounted on the telescopic end of the hydraulic rod 204. The connecting plate 205 is connected to the annular plate 103. When water is filled into the annular water bladder 102, the hydraulic rod 204 is activated, causing its telescopic end to move the connecting plate 205 upward. The upward movement of the connecting plate 205 causes the annular plate 103 to move upward. The upward movement of the annular plate 103 causes the top of the annular water bladder 102 to be pulled up, thereby assisting the annular water bladder 102 to stand up, which is beneficial to improving the stability of the annular water bladder 102. A base plate 202 is installed at the bottom of the support frame 201. A positioning hole 203 is provided through the base plate 202. The positioning hole 203 is used in conjunction with fasteners, such as bolts, to fix the base plate 202 in a designated position for effective support of the hydraulic rod 204.

[0029] like Figure 2 As shown, the input end of the second water pump 305 is equipped with a fourth water pipe 307 that communicates with the inside of the annular water bladder 102, and the output end of the second water pump 305 is equipped with a third water pipe 306 that communicates with the inside of the water tank 301. When the tooling body 5 completes the strength verification of the hull, the second water pump 305 is started to draw water out of the annular water bladder 102 through the fourth water pipe 307, and then discharged back into the water tank 301 for collection through the third water pipe 306.

[0030] like Figure 1 , Figure 4 and Figure 5 As shown, a water collection assembly 4 is provided on the outside of the collection box 101. The water collection assembly 4 includes an interception box 401. The support assembly 2 is located between the water collection assembly 4 and the protective structure 1. An annular groove 402 is provided on the interception box 401. A cover plate 403 is placed on the annular groove 402. Multiple filter holes 404 are provided through the cover plate 403. According to the above technical solution, if the annular water bag 102 is punctured by a hull part, water will flow out from the inside of the annular water bag 102. At this time, the water enters the interception box 401 through the filter holes 404 for collection, thus avoiding water overflow as much as possible. A water-drawing pipe 405 is installed on the cover plate 403. The internal thread of the water-drawing pipe 405 is connected to a threaded plug 406, which allows the hose connected to the water pump's pumping end to be inserted into the interception box 401 to facilitate the extraction of water collected in the interception box 401. The threaded plug 406 is used to block the inside of the water-drawing pipe 405. The ground needs to be dug again, and the interception box 401 is placed in the pit. The top of the cover plate 403 should be level with the ground.

[0031] Working principle like Figures 1-5 As shown, by starting the first water pump 302, water is drawn out of the water tank 301 through the first water pipe 303, and then water is filled into the annular water bladder 102 through the second water pipe 304, thereby causing the annular water bladder 102 to expand and stand on the outside of the tool body 5. When the hull parts are launched, the elasticity of the annular water bladder 102 and the water inside it buffer the hull parts, thus avoiding secondary launch of the hull parts as much as possible. If the annular water bladder 102 is punctured by the hull parts, no new fragments or dangerous parts will be generated. While water is being filled into the annular water bladder 102, the hydraulic rod 204 is activated, causing its telescopic end to move the connecting plate 205 upward. The upward movement of the connecting plate 205 causes the annular plate 103 to move upward, and the upward movement of the annular plate 103 causes the top of the annular water bladder 102 to be pulled up, thereby assisting the annular water bladder 102 to stand up, which is beneficial to improving the stability of the annular water bladder 102. If the annular water bladder 102 is punctured by a hull part, water will flow out from inside the annular water bladder 102. At this time, the water will enter the interception box 401 through the filter hole 404 for collection, thus avoiding water overflow as much as possible.
