Description

Technical Field

[0001] The invention relates to a cable testing technology, in particular to a polyethylene fiber cable tension testing tool. Background Art

[0002] Ships and marine structures require mooring with cables and rigging when docked at a pier, and also when docked at a floating dock. Cables and rigging are also required, forming an elastic constraint system between the cable, the ship, and the bollard. The mooring pattern and pretension within this system are key to the mooring system. When moored at a pier or floating dock, ships and marine structures experience a certain amount of motion due to external loads such as wind, waves, and currents. The initial force and pretension of the cables affect the ship's motion under different external forces, further affecting the variation in the cable force under these external forces, thus impacting the mooring safety of the ship or marine structure.

[0003] Chinese invention patent publication number CN116891159A discloses an adaptive cable pretension adjustment device. This device uses a series spring to simulate the cable's stiffness curve, driving a servo motor to extend and retract the spring assembly to adjust and calibrate the mooring pretension. A tension sensor measures the tension acting on the cable in real time, determining the initial pretension. This ensures that the mooring force is minimally affected by friction, resulting in more realistic test results. This device is primarily used for mooring model testing in shipbuilding and marine engineering.

[0004] When used, existing equipment cannot meet the requirements of tensile testing at different angles, resulting in a single test result and an inability to obtain relatively accurate results, which in turn affects the actual data of the cable. At the same time, during the test, the cable may slip under the action of tension, causing the cable to fall off during the test, causing the operator to be impacted. Therefore, a polyethylene fiber cable tensile test tool has been developed. Summary of the Invention

The adjustment component 2 is used to perform tension tests on the cable at different angles.

[0036] In this solution, the telescopic member 12 is a component with a telescopic function such as an electric telescopic rod, and is connected to an external control device. When the telescopic member 12 is started, it can drive the adjustment component 2 set at its output end to move until it reaches the optimal position and stops.

A movable groove is provided at the end of the movable plate 282, and the inner wall of the movable groove is slidingly connected to the outer surface of the lower end of the limit block 281. Since the end of the push plate 27 is rotationally connected to the outer surface of the positioning plate 28, and the outer surface of the positioning plate 28 is slidingly connected to one side of the limit block 281, when the swing block 26 rotates, the positioning plate 28 and the limit block 281 are driven to move on the inner wall of the movable groove until the positioning plate 28 reaches the optimal position.

At the same time, when the telescopic rod 242 is started, it synchronously drives the adjustment ring 24 set at its output end to move, wherein an annular groove is provided at the end of the adjustment ring 24, and the inner wall of the annular groove is slidably connected to the outer surface of the output end of the telescopic rod 242, so that when the adjustment ring 24 rotates, it will not be interfered with by the telescopic rod 242.

[0046] The inner wall of the adjustment ring 24 is provided with a guide block, the outer surface of the driving rod 23 is provided with a driving groove, and the inner wall of the driving groove is slidably connected to the outer surface of the guide block, so that the adjustment ring 24 can be driven to rotate when the driving rod 23 rotates.

[0050] Specifically, when the slider 25 moves along the inner wall of the arc plate 231, it synchronously drives the connecting block 251 to move. Since the connecting block 251 is rotationally connected to the swing block 26, when the arc plate 231 rotates following the driving rod 23, it drives the swing block 26 to rotate around the positioning axis 261.

[0051] Furthermore, a guide groove 13 is formed at the upper end of the bottom plate 11 , and the inner wall of the guide groove 13 is slidably connected to the outer surface of the lower end of the movable plate 21 .

[0052] Specifically, when the movable plate 21 moves, the push plate 27 cooperates to drive the positioning plate 28 to move up and down along the inner wall of the limit block 281, thereby adjusting the angle of the cable to make it suitable for different scenarios.

[0056] Specifically, the power member 32 is a component with telescopic function such as an electric telescopic rod, and the power member 32 drives the power rod 34 to move. Since the end of the power rod 34 is connected to the outer surface of the power block 35, when the power rod 34 moves, the power block 35 is synchronously driven to move, wherein the power block 35 is slidably installed on the inner wall of the slide groove 36, so that when the power block 35 is subjected to force, the power block 35 is driven to move along the inner wall of the slide groove 36 until it reaches the optimal position.

[0057] Furthermore, a first arc groove 37 is symmetrically opened at the end of the protective plate 33, and a second arc groove 38 is symmetrically opened on the protective plate 33 and located on one side of the first arc groove 37; two stretching rods 351 are rotatably installed on the outer surface of the power block 35, and the ends of the two stretching rods 351 are rotatably installed with a splint 39, and the outer surface of the splint 39 is slidingly connected to the inner walls of the first arc groove 37 and the second arc groove 38 respectively.

[0059] The control device can use a single-chip microcomputer as the control terminal. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (MCU), consisting of an arithmetic unit, a controller, memory, and input / output devices, equivalent to a miniature computer. Compared to the general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings.
