Description

Technical Field

[0001] This invention relates to the field of anchor chain wear testing technology, specifically to a buoy anchor chain wear testing inspection table and its usage method. Background Technology

[0002] A buoy anchor chain is a device consisting of a chain and an anchor, typically used to secure a buoy so that it can be moored in a designated location. The chain of a buoy anchor chain is usually made of high-strength steel, which has high tensile strength and wear resistance, and can withstand the impact and abrasion of natural conditions such as waves and tides.

[0003] Under current technology, buoy anchor chains need to undergo regular wear tests to promptly identify the wear condition of the anchor chain and replace it in time to avoid buoy loss due to breakage. There are many testing methods available today, among which the length measurement method is commonly used. The standard length is taken as the length after stretching a newly produced standard buoy anchor chain. Then, the anchor chain to be tested is stretched and its length is measured to obtain the amount of deformation, thereby determining whether it is excessively worn.

[0004] However, when conducting tests on current testing benches, we have found that the anchor chain is generally quite long, so the overall length or height of the testing bench is also very long and high. When fixing it, we find that due to the angle of twisting or the fixed position, certain errors will occur in the measurement, and it is not convenient to measure multiple sections.

[0005] Therefore, we propose a buoy anchor chain wear testing platform and its usage method that can accurately fix the anchor chain to avoid errors and perform multi-section testing, in order to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a buoy anchor chain wear testing and inspection platform and its usage method to solve the problems mentioned in the background art.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A buoy anchor chain wear testing platform includes a testing platform. Slide grooves are formed on both sides of the top of the testing platform. A fixed column is slidably connected to one side of each slide groove. A fixed limiting plate is hinged to the top of the testing platform on one side of the fixed column. A movable column is slidably connected to the middle position inside the slide groove. Insert rods are slidably connected to the upper ends of both the movable and fixed columns. A nut is threaded onto one side of each insert rod, and a fixing member is fixedly connected to the other side. An intermediate frame is fixedly connected to the middle position of the top of the testing platform. A scale is fixedly connected to the top of the intermediate frame. Indicator rods are fixedly connected to the top of the movable column on one side of the scale.

[0009] As a further embodiment of the present invention: a fixed box is symmetrically fixedly connected to the bottom end of the inspection table, a servo motor is fixedly connected to one side of the fixed box, a lead screw is fixedly connected to the output end of the servo motor, a lead screw nut is threadedly connected to the outer surface of the lead screw, and a movable limiting plate is hinged to the top end of the lead screw nut.

[0010] As a further aspect of the present invention: both sides of the slide groove penetrate the sidewall of the inspection table, and the bottom ends of the movable column and the fixed column are both I-shaped and matched with the slide groove.

[0011] As a further embodiment of the present invention: hinge plates are symmetrically hinged on both sides of the inspection table, and a support plate is fixedly connected to the bottom end of the side wall of the inspection table on one side of the hinge plate, and the hinge plate is located on one side of the slide groove.

[0012] As a further aspect of the present invention: a support column is uniformly slidably connected to the other side of the slide groove, a slide rod is slidably connected to the upper end of the support column, and a threaded sleeve is threadedly connected to one side of the slide rod.

[0013] As a further aspect of the present invention: the upper ends of the movable column, the fixed column and the supporting column are all provided with placement grooves, and the height of the placement grooves is equal to the diameter of the anchor chain ring.

[0014] As a further aspect of the present invention: the outer wall of the fixing member near the insertion rod is provided with a cut edge, and both sides of the fixing member are in contact with the middle stop of an anchor chain and the outer wall of another anchor chain ring.

[0015] As a further aspect of the present invention: one side of the indicator rod is in contact with the side wall of the scale.

[0016] As a further aspect of the present invention: the shape of the fastener is T-shaped, and the height of one side of the fastener is equal to the width of the anchor chain ring.

[0017] A method for using a buoy anchor chain wear testing bench includes the following steps:

[0018] S1: First, place the end anchor chain ring of the standard buoy anchor chain and the adjacent anchor chain ring vertically on the upper end of the fixed column, so that the adjacent anchor chain ring is horizontally inserted into the placement groove for limitation, and then insert the rod through the fixed column to limit the end anchor chain ring of the fixing component, and rotate the nut to fix it.

[0019] S2: Then fix any one link in the anchor chain to the movable column according to the above steps, and record the number of links from the end anchor chain link to this anchor chain link;

[0020] S3: Rotate the fixed limit plate and the movable limit plate to limit the fixed column and the movable column respectively, and align the subsequent anchor chain ring with the upper end of the support column. By passing through and fixing the slide rod, the subsequent anchor chain is supported and fixed.

[0021] S4: Start the servo motor to work with the lead screw and nut to drive the movable column until the anchor chain is straightened. At this time, read the length by the indicator on the scale and record the length.

[0022] S5: Change the number of anchor chain sections from the end anchor chain ring to the side of the movable column, and conduct the test according to the above steps, and record the length;

[0023] S6: Test the anchor chain ring to be tested according to the above steps, record the length, and then compare it with the length measured by the standard anchor chain to calculate the deformation rate, thereby determining whether the wear exceeds the standard.

[0024] S7: Based on the corresponding number of sections, promptly determine if a section of the anchor chain is worn beyond the standard.

[0025] The beneficial effects of this invention are:

[0026] 1. The present invention relates to a buoy anchor chain wear testing platform and its usage method, wherein the end anchor chain ring of the standard buoy anchor chain and the adjacent anchor chain ring are vertically placed on the upper end of a fixed column or a movable column, so that the adjacent anchor chain rings are horizontally locked into the placement groove for limiting, thereby ensuring that the anchor chain rings will not be misaligned or shifted initially. Then, a fixing member is inserted to fix the anchor chain rings, thereby ensuring that no large errors will occur during subsequent anchor chain testing.

[0027] 2. The present invention provides a buoy anchor chain wear testing and inspection platform and its usage method. By changing the number of anchor chain links from the end anchor chain ring to the movable column side, the length of multiple anchor chain links can be tested. This allows for timely identification of which anchor chain link has significant wear, enabling precise positioning and facilitating subsequent replacement.

[0028] 3. The buoy anchor chain wear testing and inspection platform and its usage method in this invention limit the fixed column by a fixed limiting plate and the movable column by a movable limiting plate. Then, the servo motor drives the lead screw to move the lead screw nut and the movable limiting plate, thereby moving the movable column and achieving good tension on the anchor chain.

[0029] 4. The buoy anchor chain wear testing platform and its usage method in this invention fix the subsequent anchor chain ring to the upper end of the support column by means of a sliding rod, so that the overall movement will not be affected by the excessive length of the subsequent anchor chain ring during the test, thus bringing certain convenience to the test.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

A fixed limiting plate 10 is hinged to the top of the inspection platform 1 on one side of the fixed column 9. A movable column 4 is slidably connected to the middle position inside the slide groove 6. Insert rods 19 are slidably connected to the upper ends of both the movable column 4 and the fixed column 9. A nut 20 is threaded onto one side of the insert rod 19, and a fixing member 15 is fixedly connected to the other side of the insert rod 19. An intermediate frame 7 is fixedly connected to the middle position of the top of the inspection platform 1. A scale 8 is fixedly connected to the top of the intermediate frame 7.

A lead screw 16 is fixedly connected to the output end of the servo motor 11. A lead screw nut 17 is threadedly connected to the outer surface of the lead screw 16. A movable limiting plate 3 is hinged to the top of the lead screw nut 17. The servo motor 11 drives the lead screw 16 to move the lead screw nut 17 and the movable limiting plate 3, thereby driving the movable column 4 to move and achieving good tensioning of the anchor chain.

[0042] In this embodiment, both sides of the slide 6 penetrate the side wall of the inspection table 1.

[0051] S2: Then fix any one link in the anchor chain to the movable column 4 according to the above steps, and record the number of links from the end anchor chain link to this anchor chain link;

[0052] S3: Rotate the fixed limiting plate 10 and the movable limiting plate 3 to limit the fixed column 9 and the movable column 4 respectively, and align the subsequent anchor chain ring with the upper end of the supporting column 5. By passing through and fixing the slide rod 22, the subsequent anchor chain is supported and fixed.

[0053] S4: Start the servo motor 11 to work with the lead screw 16 and lead nut 17 to drive the movable column 4 to move until the anchor chain is straightened. At this time, read the length by the indicator rod 14 on the scale 8 and record the length.

[0054] S5: Change the number of anchor chain sections from the end anchor chain ring to the anchor chain on one side of the movable column 4, and conduct the test according to the above steps, and record the length;

[0055] S6: Test the anchor chain ring to be tested according to the above steps, record the length, and then compare it with the length measured by the standard anchor chain to calculate the deformation rate, thereby determining whether the wear exceeds the standard.

[0056] S7: Based on the corresponding number of sections, promptly determine if a section of the anchor chain is worn beyond the standard.

[0057] The complete usage steps and working principle of this invention are as follows:

[0058] First, place the end anchor chain ring and the adjacent anchor chain ring of the standard buoy anchor chain vertically on the upper end of the fixed column 9, so that the adjacent anchor chain ring is horizontally inserted into the placement groove 18 for limiting. Then, pass the insertion rod 19 through the fixed column 9 to limit the end anchor chain ring with the fixing member 15, and rotate the nut 20 to fix it. Then, fix any ring of the anchor chain to the movable column 4 according to the above steps, and record the number of links from the end anchor chain ring to this anchor chain ring. Then, rotate the fixed limiting plate 10 and the movable limiting plate 3 to fix the fixed column 9 and the movable column 4 respectively. Limit the position and align the subsequent anchor chain ring with the upper end of the support column 5. By passing through and fixing the slide rod 22, the subsequent anchor chain is supported and fixed. Start the servo motor 11 to work with the lead screw 16 and lead nut 17 to drive the movable limit plate 3 to move the movable column 4 until the anchor chain is straightened. At this time, read the value on the scale 8 through the indicator rod 14 and record the length. Change the number of anchor chain sections from the end anchor chain ring to the side of the movable column 4, and conduct the test according to the above steps, and record the length to provide comparison parameters for the subsequent anchor chain.

[0059] Then, the anchor chain ring to be tested is tested according to the above steps, and the length is recorded. The length is then compared with that of the standard anchor chain to calculate the deformation rate. This is used to determine whether the wear exceeds the standard, and the wear of a certain section of the anchor chain is promptly determined based on the corresponding number of sections.
