Description

Technical Field

[0001] This utility model relates to the field of ship anchor testing, specifically to a ship anchor testing device. Background Technology

[0002] Anchoring is a safe operation in which a ship releases its anchorage to the seabed and uses the anchor's holding power to secure itself in a fixed position. Anchoring tests are scientific testing procedures that verify the structural strength, holding power performance, and reliability of the anchorage. They need to simulate the stress state under actual sea conditions. Anchoring test equipment is a specialized device for performing these tests, such as adjustable dual-axis anchor claw fixing mechanisms and gear-linked dynamic simulation devices. These devices use physical structures to test the anchor claw clamping, anchor chain tension, and winding tension. These three elements form a logical chain of "operational requirements - performance verification - tool support": the safe implementation of anchoring depends on the scientific verification of anchoring tests, and the test equipment, as a verification tool, ensures that the test results meet international standards through physical structural innovation, ultimately guaranteeing the safety of ship anchoring.

[0003] Existing ship anchor testing equipment lacks the ability to comprehensively test multiple anchor sizes, which leads to the need for manual adjustment of clamps, the inability to automatically adapt to different anchor head sizes, and limited functionality. The equipment also requires frequent replacement of test modules and cannot simulate the dynamic winding process, resulting in test results that cannot fully reflect the performance of the anchor in actual anchoring.

[0004] Therefore, it is necessary to invent a ship anchor testing device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a ship anchor pulling test device. Through an anchor head contact fixing block, a central measuring groove, a telescopic cylinder, a first conical block, a pulling screw, a second conical block, and a total winding and pulling plate, the device enables comprehensive testing of multiple anchor sizes. The adjustable spacing design of the anchor head contact fixing block allows for compatibility with anchors of different sizes, avoiding the need for switching between multiple devices or frequent adjustments, thus improving testing efficiency. Simultaneously, multi-specification testing can reveal differences in anchor holding power under different conditions, avoiding performance misjudgments caused by single-specification testing. This addresses the shortcomings of existing technologies that lack comprehensive testing capabilities for multiple anchor sizes. Such technologies often require manual adjustment of clamps, cannot automatically adapt to different anchor head sizes, have limited functionality, require frequent changes of test modules, and cannot simulate dynamic winding processes, resulting in test results that do not fully reflect the anchor's performance during actual anchor pulling.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ship anchor pulling test device, including a test bench and a main body for ship anchor pulling tests;

[0007] A fixed adjustment groove is provided above the test bench for anchor head fixing. A micro motor is fixedly installed on the outside of the fixed adjustment groove. A bidirectional screw is fixedly installed at the output end of the micro motor. An external threaded sleeve is connected to the external threaded sleeve. An anchor head abutment fixing block is fixedly installed above the external threaded sleeve. A center measurement groove is provided at the center of the top of the test bench.

[0008] A telescopic cylinder is fixedly installed inside the intermediate test groove for conducting intermediate chain tests. A first conical block is fixedly installed at the front end of the telescopic cylinder, and a pulling screw is passed through the external thread of the first conical block.

[0009] A fixed frame is fixedly installed above the test bench for overall anchor testing of ships. A servo motor is fixedly installed on the outside of the fixed frame, and a main winding and pulling plate is fixedly installed at the output end of the servo motor.

[0010] Preferably, the anchor head abutting the fixing block is slidably connected to the test bench, and the two ends of the bidirectional screw have opposite thread directions.

[0011] Preferably, a display screen is fixedly installed on the outside of the test bench, and two sets of anchor head abutting fixing blocks are internally connected with pull anchor heads, and pull anchor chains are fixedly connected to the outside of the pull anchor heads.

[0012] Preferably, the first conical block is telescopically connected to the central groove, and the pulling screw passes through the middle of the anchor chain.

[0013] Preferably, the other end of the pulling screw is threadedly connected to a second conical block, and the first and second conical blocks are symmetrically arranged about the central axis of the central groove.

[0014] Preferably, a chain-linked spiked roller is fixedly installed inside the main winding measuring plate, and an anchor chain is wound around the outside of the chain-linked spiked roller.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] This utility model includes an anchor head contact fixing block, a central measuring groove, a telescopic cylinder, a first conical block, a pulling screw, a second conical block, and a main winding and measuring plate. When using this ship anchor pulling test device, the spacing between the two sets of anchor head contact fixing blocks can be adjusted according to the different sizes and spacings of the current anchor heads, allowing anchor heads of different sizes to be positioned between the two sets of anchor head contact fixing blocks. Before conducting the overall test, one set of the first and second conical blocks can be connected to one end of the anchor pulling chain via the pulling screw, while the other end is operated in the same way with the other set. This allows the telescopic cylinder to extend and retract, thus testing the tension of the anchor chain. The main winding test plate can then wind up the anchor chain, while the anchor head contact fixing block holds the anchor head in place, testing the overall tensile strength of the ship's anchor. This gives the ship's anchor testing device the ability to comprehensively test multiple anchor sizes. Furthermore, the adjustable spacing of the anchor head contact fixing block allows for compatibility with anchors of different sizes, avoiding the need for switching between multiple devices or frequent adjustments, thus improving testing efficiency. Simultaneously, multi-specification testing can reveal differences in anchor holding power under different conditions, avoiding performance misjudgments caused by testing only one specification.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-5 The device shown is a ship anchor pulling test device, including a test bench 1 and a main body for ship anchor pulling tests;

[0027] A fixed adjustment groove 2 is provided above the test bench 1 for anchor head fixing. A micro motor 3 is fixedly installed on the outside of the fixed adjustment groove 2. A bidirectional screw 4 is fixedly installed at the output end of the micro motor 3. An external threaded sleeve 5 is connected to the external threaded sleeve 4. An anchor head abutment fixing block 6 is fixedly installed above the external threaded sleeve 5. A center measurement groove 10 is provided at the center of the top of the test bench 1.

[0028] Telescopic cylinder 11 is fixedly installed inside the intermediate test groove 10 for intermediate chain test, and a first conical block 12 is fixedly installed at the front end of telescopic cylinder 11, and a pulling screw 13 passes through the external thread of the first conical block 12.

[0029] A fixed frame 15 is fixedly installed above the test bench 1 for overall anchor testing of the ship. A servo motor 16 is fixedly installed on the outside of the fixed frame 15. A total winding and tension testing plate 17 is fixedly installed at the output end of the servo motor 16. Before the overall test, a set of first conical blocks 12 and second conical blocks 14 can be connected to pull one end of the anchor chain 9 through the pulling screw 13. The other end is operated in the same way by another set. This causes the telescopic cylinder 11 to extend and retract, thereby testing the tension of the anchor chain 9. Then, the total winding and tension testing plate 17 can be used to wind up the anchor chain 9. The anchor head abuts against the fixed block 6, which abuts against the anchor head 8, thereby testing the overall tensile strength of the ship's anchor. This gives the ship's anchor testing device the ability to comprehensively test multiple specifications of anchors.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, the anchor head contact fixing block 6 is slidably connected to the test bench 1. The two ends of the bidirectional screw 4 have opposite thread directions. According to the different sizes and spacing of the current anchor heads 8, the spacing between the two sets of anchor head contact fixing blocks 6 can be adjusted to allow different sizes of anchor heads 8 to be locked in the middle of the two sets of anchor head contact fixing blocks 6. A display screen 7 is fixedly installed on the outside of the test bench 1. The anchor heads 8 are internally connected to the two sets of anchor head contact fixing blocks 6. An anchor chain 9 is fixedly connected to the outside of the anchor head 8. The display screen 7 can display the tensile strength of the chain and the overall tensile strength test data of the ship's anchor, so as to facilitate external operators to observe and record.

[0031] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the first conical block 12 is telescopically connected to the central measuring groove 10. The pulling screw 13 passes through the middle of the anchor chain 9, allowing a set of first conical blocks 12 and second conical blocks 14 to be connected to one end of the anchor chain 9 via the pulling screw 13. The other end is operated in the same way, thus extending and retracting the telescopic cylinder 11 to test the tension of the anchor chain 9. The other end of the pulling screw 13 is threadedly connected to the second conical block 14. The first conical block 12 and the second conical block 14 are symmetrically arranged about the central axis of the central measuring groove 10. The overall structure of the pulling screw 13 is simple and easy to operate, and it is convenient for maintenance personnel to replace it in time if a fault occurs. The chain spike roller 18 is fixedly installed inside the main winding and tension testing plate 17. The anchor chain 9 is wound around the outside of the chain spike roller 18. The chain spike roller 18 can make the chain wound more tightly when the main winding and tension testing plate 17 rotates, thereby improving the stability of the overall tension test.

[0032] The working principle of this practical system is as follows: First, connect the external power supply and place the ship's anchor to be tested on the test bench 1. Place the anchor chain 9 in the center test groove 10, and wrap the other end of the anchor chain 9 around the chain spike roller 18 of the main winding test plate 17. Then, depending on the size and spacing of the anchor heads 8, turn on the switch of the micro motor 3 to drive the bidirectional screw 4 to rotate, so that the bidirectional screw 4 drives the anchor head to abut against the fixing block 6, thereby adjusting the spacing between the two sets of anchor head abutting fixing blocks 6, so that anchor heads 8 of different sizes are stuck in the middle of the two sets of anchor head abutting fixing blocks 6. Then, before the overall test, a set of first conical blocks 12 and second conical blocks 14 can be connected to one end of the anchor chain 9 through the pulling screw 13, and the other end is operated in the same way with another set. Then, extend and retract the telescopic cylinder 11 to test the tension of the anchor chain 9. Afterwards, the switch of the servo motor 16 can be turned on to allow... The main winding and testing plate 17 winds up the anchor chain 9, and the anchor head abutting the fixing block 6 abuts the anchor head 8, thus testing the overall tensile strength of the ship's anchor. This gives the ship's anchor testing device the ability to comprehensively test multiple specifications of anchors. Through the adjustable spacing design of the anchor head abutting the fixing block 6, it can be compatible with anchors of different sizes, avoiding switching between multiple devices or frequent adjustments, thus improving testing efficiency. At the same time, multi-specification testing can reveal the differences in the holding force of anchors under different conditions, avoiding performance misjudgments caused by single-specification testing. The test data can be displayed on the screen 7, which is convenient for external operators to observe and record. Finally, after completing the installation and use of the ship's anchor testing device according to the above operations, turn off the switch of the micro motor 3, the switch of the telescopic cylinder 11, and the switch of the servo motor 16. If it is not used for a long time, simply disconnect the external power supply. In this way, the use of the ship's anchor testing device is completed.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
