Description

Technical Field

[0001] The invention belongs to the technical field of ship anchor chain detection, and in particular relates to a tensile strength test device for ship anchor chain production. Background Art

[0002] Ship anchor chain is an important equipment for mooring. It is usually composed of a series of underwater metal links, which are connected by welding or other means to form a chain. It mainly forms sufficient tension at the anchor position and anchoring point of the ship through the weight and length of the anchor chain, so that the ship can be safely kept in the desired position. Ship anchor chain plays an important role in the process of ship mooring and anchoring, so it is of great significance to test its tension performance.

[0003] However, in the prior art, when testing the tensile strength of the anchor chain, external tension is mainly applied to both ends of the anchor chain to observe whether the anchor chain breaks. The current tensile strength test generally only applies horizontal tension on both sides, that is, only simulates the stress condition of the anchor chain in a static state. However, when the anchor chain is actually used, one end of the anchor chain will shake up and down due to the action of waves. In addition, when the anchor sinks to the bottom of the sea, the hull will continue to move, so the angle between the anchor chain and the hull is also constantly changing, which makes the test data obtained by the test inaccurate. Summary of the invention

[0008] In the above technical solution, further, a No. 2 motor is fixedly connected to the top of the base, and an output end of the No. 2 motor is fixedly connected to one side of the cam.

[0009] In the above technical solution, further, the side extrusion mechanism includes a disc, which is fixedly connected above the movable seat, the outer wall of the disc is fixedly connected to a worm gear, the inner part of the disc is slidably connected to a limit block, and one side of the limit block is fixedly connected to a fixed seat.

[0010] In the above technical solution, further, a worm is rotatably connected inside the fixed seat, the worm is meshed with the outer wall of the worm wheel, the fixed seat is slidably connected to the outer wall of the disc, a No. 3 motor is fixedly connected to one side of the fixed seat, and the output end of the No. 3 motor is fixedly connected to one end of the worm.

[0011] In the above technical solution, further, a No. 2 electric cylinder is fixedly connected to one side of the fixing seat, and an output end of the No. 2 electric cylinder is fixedly connected to an extrusion rod.

[0012] In the above technical solution, further, the changing mechanism includes a connecting plate, one side of the fixed plate is fixedly connected to an electric cylinder No. 1, the output end of the electric cylinder No. 1 is fixedly connected through the fixed plate and one side of the connecting plate, one side of the connecting plate is fixedly connected to a motor No. 4, the motor No. 4 and some rotations of the connecting plate are connected to a turntable, and one side of the turntable is fixedly connected to a protrusion.

[0013] In the above technical solution, further, the outer wall of the turntable and the output end of the fourth motor are fixedly connected with bevel gears, the two bevel gears are meshed, one side of the connecting plate is slidably connected with a slider, one side of the slider is slidably connected with a slide plate, one side of the slide plate is provided with a horizontal groove and a vertical groove, and the two protrusions are slidably connected inside the horizontal groove and the vertical groove respectively.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the staff can hang the two ends of the anchor chain on the mounting plate and the hook on one side of the slide plate respectively, and then start the No. 1 electric cylinder. After starting, the No. 1 electric cylinder will pull the anchor chain. During the pulling process of the anchor chain, the No. 2 motor can be started. After starting, the No. 2 motor will drive the cam to rotate. During the rotation of the cam, since the two ends of the connecting rod are respectively connected with the sliding rod and the internal rotation of the cam, the No. 2 motor will drive the sliding rod to slide back and forth in the up and down directions after starting, so as to achieve the purpose of vibrating the mounting plate. Through the up and down movement of the mounting plate, one end of the anchor chain is made to shake up and down to simulate the tensile strength of the anchor chain under the action of waves, so as to ensure that the test is more accurate.

[0015] 2. In the present invention, if it is necessary to squeeze the side wall of the anchor chain, the staff can start the No. 2 electric cylinder to extend the output end of the No. 2 electric cylinder, and then the arc-shaped side of the squeezing rod will complete the squeezing of the side of the anchor chain, thereby improving the comprehensiveness of the anchor chain detection. In addition, when the staff can start the No. 3 motor, the No. 3 motor will drive the worm to rotate after it is started. Because the worm and the worm wheel are meshed and the worm wheel is fixedly connected to the outer wall of the disc and cannot rotate, the worm will drive the fixed seat to slide on the outer wall of the disc when it rotates. The sliding of the fixed seat on the outside of the disc can change the angle between the output end of the No. 2 electric cylinder, i.e., the squeezing rod and the anchor chain, so that the squeezing rod can complete the squeezing of the anchor chain from different angles, thereby simulating the situation that the anchor chain touches the reef in the sea.

[0016] 3. In the present invention, the staff can control the rotation of the two No. 4 motors. After the No. 4 motor is started, it will drive the turntable to rotate. When the turntable rotates, the protrusions will squeeze the inner walls of the horizontal groove and the vertical groove. When the turntable on one side of the horizontal groove rotates, the inner wall of the horizontal groove is squeezed by the protrusions, and the slide plate will move in the vertical direction. Similarly, when the turntable on one side of the vertical groove rotates, the inner wall of the vertical groove is squeezed by the protrusions. At this time, the slide plate will move laterally. The slide plate can be used to move laterally and vertically at the same time, so the angle between the anchor chain and the mounting plate can be changed, thereby simulating the pulling of the anchor chain by the hull when it moves after the anchor is fixed to the seabed, so as to more realistically simulate the actual situation of the anchor chain in the sea.

[0022] In this embodiment, the staff can hang the two ends of the anchor chain on the mounting plate 11 and the hook 12 on one side of the slide plate 47 respectively, and then start the No. 1 electric cylinder 17. After starting, the No. 1 electric cylinder 17 will pull the anchor chain. During the pulling process of the anchor chain, the No. 2 motor 25 can be started. After starting, the No. 2 motor 25 will drive the cam 22 to rotate. During the rotation of the cam 22, since the two ends of the connecting rod 23 are respectively connected with the sliding rod 24 and the internal rotation of the cam 22, the No. 2 motor 25 will drive the sliding rod 24 to slide back and forth in the up and down directions after starting, so as to achieve the purpose of vibrating the mounting plate 11. Through the up and down movement of the mounting plate 11, one end of the anchor chain is made to shake up and down to simulate the tensile strength of the anchor chain under the action of waves, thereby ensuring that the test is more accurate.

[0023] Embodiment 2 like Figure 1 - Figure 7The tensile strength test device for ship anchor chain production shown in the figure comprises a side extrusion mechanism 3 including a disc 31, the disc 31 is fixedly connected above the movable seat 16, a worm gear 32 is fixedly connected to the outer wall of the disc 31, a limit block 35 is slidably connected inside the disc 31, a fixed seat 33 is fixedly connected to one side of the limit block 35, a worm 34 is rotatably connected inside the fixed seat 33, the worm 34 is meshed with the outer wall of the worm gear 32, the fixed seat 33 is slidably connected to the outer wall of the disc 31, a No. 3 motor 36 is fixedly connected to one side of the fixed seat 33, the output end of the No. 3 motor 36 is fixedly connected to one end of the worm gear 34, a No. 2 electric cylinder 37 is fixedly connected to one side of the fixed seat 33, and an extrusion rod 38 is fixedly connected to the output end of the No. 2 electric cylinder 37.

[0024] In this embodiment, if it is necessary to squeeze the side wall of the anchor chain, the staff can start the No. 2 electric cylinder 37 to extend the output end of the No. 2 electric cylinder 37, and then the arc-shaped side of the squeezing rod 38 will complete the squeezing of the side of the anchor chain, thereby improving the comprehensiveness of the anchor chain detection. In addition, when the staff can start the No. 3 motor 36, the No. 3 motor 36 will drive the worm 34 to rotate after it is started. Because the worm 34 and the worm wheel 32 are meshed and the worm wheel 32 is fixedly connected to the outer wall of the disc 31 and cannot rotate, the worm 34 will drive the fixing seat 33 to slide on the outer wall of the disc 31 when it rotates. The sliding of the fixing seat 33 on the outside of the disc 31 can change the angle between the output end of the No. 2 electric cylinder 37, that is, the squeezing rod 38 and the anchor chain, so that the squeezing rod 38 can complete the squeezing of the anchor chain from different angles, further improving the detection range of the anchor chain.

[0025] Embodiment 3 like Figure 1 - Figure 7 A tensile strength test device for ship anchor chain production is shown, and the changing mechanism 4 includes a connecting plate 41, one side of the fixed plate 13 is fixedly connected to the No. 1 electric cylinder 17, the output end of the No. 1 electric cylinder 17 passes through the fixed plate 13 and is fixedly connected to one side of the connecting plate 41, one side of the connecting plate 41 is fixedly connected to the No. 4 motor 42, the No. 4 motor 42, one side of the connecting plate 41 is rotatably connected to a turntable 43, one side of the turntable 43 is fixedly connected to a protrusion 45, the outer wall of the turntable 43 and the output end of the No. 4 motor 42 are both fixedly connected to a bevel gear 44, the two bevel gears 44 are meshed, one side of the connecting plate 41 is slidably connected to a slider 46, one side of the slider 46 is slidably connected to a slide plate 47, one side of the slide plate 47 is provided with a transverse groove 48 and a vertical groove 49, and two protrusions 45 are slidably connected to the inside of the transverse groove 48 and the vertical groove 49 respectively.

[0026] In this embodiment, the staff can control the rotation of the two No. 4 motors 42. Since the output end of the No. 4 motor 42 and the turntable 43 are connected by the bevel gear 44, the No. 4 motor 42 will drive the turntable 43 to rotate after it is started. When the turntable 43 rotates, the protrusion 45 will squeeze the inner walls of the horizontal groove 48 and the vertical groove 49. When the turntable 43 on one side of the horizontal groove 48 rotates, the inner wall of the horizontal groove 48 is squeezed by the protrusion 45, and the slide plate 47 will move in the vertical direction. Similarly, when the turntable 43 on one side of the vertical groove 49 rotates, the inner wall of the vertical groove 49 is squeezed by the protrusion 45. At this time, the slide plate 47 will move laterally. The slide plate 47 can be used for both horizontal and vertical movement at the same time, so that the angle between the anchor chain and the mounting plate 11 can be changed, thereby simulating the pulling of the anchor chain by the hull when it moves after the anchor is fixed to the seabed, so as to more realistically simulate the actual situation of the anchor chain in the sea, thereby improving the accuracy of the anchor chain detection.

[0027] Working principle: the staff can hang the two ends of the anchor chain on the mounting plate 11 and the hook 12 on one side of the slide plate 47, and then start the No. 1 electric cylinder 17. After starting, the No. 1 electric cylinder 17 will pull the anchor chain. During the pulling process of the anchor chain, the No. 2 motor 25 can be started. After starting, the No. 2 motor 25 will drive the cam 22 to rotate. During the rotation of the cam 22, because the two ends of the connecting rod 23 are respectively connected to the sliding rod 24 and the internal rotation of the cam 22, the No. 2 motor 25 will drive the sliding rod 24 to slide back and forth in the up and down directions after starting, so as to achieve the purpose of vibrating the mounting plate 11. 11 moves up and down, thereby making one end of the anchor chain shake up and down to simulate the tensile strength of the anchor chain under the action of waves, ensuring that the test is more accurate. If it is necessary to squeeze the side wall of the anchor chain, the staff can start the No. 2 electric cylinder 37 to extend the output end of the No. 2 electric cylinder 37, and then the arc-shaped side of the squeezing rod 38 will complete the squeezing of the side of the anchor chain, thereby improving the comprehensiveness of the anchor chain detection. In addition, when the staff can start the No. 3 motor 36, the No. 3 motor 36 will drive the worm 34 to rotate after it is started. Because the worm 34 is meshed with the worm wheel 32 and the worm wheel 32 is fixedly connected to the outer wall of the disc 31 and cannot rotate, the worm When the No. 34 rotates, the fixing seat 33 will be driven to slide on the outer wall of the disc 31. The sliding of the fixing seat 33 on the outside of the disc 31 can change the angle between the output end of the No. 2 electric cylinder 37, that is, the squeezing rod 38 and the anchor chain, so that the squeezing rod 38 can squeeze the anchor chain from different angles, further improving the detection range of the anchor chain. In addition, the staff can control the rotation of the two No. 4 motors 42. Because the output end of the No. 4 motor 42 and the turntable 43 are connected by the bevel gear 44, the No. 4 motor 42 will drive the turntable 43 to rotate after it is started. When the turntable 43 rotates, the protrusion 45 will contact the transverse groove 48 and The inner wall of the vertical groove 49 is squeezed, and when the turntable 43 on one side of the transverse groove 48 rotates, the inner wall of the transverse groove 48 is squeezed by the protrusion 45, and the slide plate 47 will move in the vertical direction. Similarly, when the turntable 43 on one side of the vertical groove 49 rotates, the inner wall of the vertical groove 49 is squeezed by the protrusion 45, and the slide plate 47 will move laterally. The slide plate 47 can move laterally and vertically at the same time, so that the angle between the anchor chain and the mounting plate 11 can be changed, thereby changing the direction of the pulling force on the anchor chain, so as to more realistically simulate the actual situation of the anchor chain in the sea, thereby improving the accuracy of the anchor chain detection.
