[0002] The six-strand nylon composite rope has extraordinary abrasion resistance, which is more than twice that of ordinary chemical fiber ropes. Coupled with its resistance to seawater, chemical corrosion, ultraviolet radiation, temperature difference, etc., it has been widely used in ship mooring and towing. During the production process of the six-strand nylon composite rope, in order to ensure the safety and quality of the six-strand nylon composite rope, the tensile test is usually carried out on the produced six-strand nylon composite rope.

[0003] According to a nylon rope tensile testing device disclosed in a Chinese patent with the publication number "CN221883294U", which includes a test bench. A fixed plate is fixedly installed on the left side of the top of the test bench. A protective mechanism is movably installed on the upper surface of the test bench. A tensile sensor is fixedly installed on the right side surface of the fixed plate. A first rope end fixing mechanism is fixedly installed on the right side surface of the tensile sensor. A moving plate is movably installed on the right side of the top of the test bench. A second rope end fixing mechanism is fixedly installed on the left side surface of the moving plate. The first rope end fixing mechanism includes a fixed seat and a cover plate. By installing devices such as the first rope end fixing mechanism, fixed seat, clamping groove, resistance-increasing teeth, top plate, spring, clamping column group, anti-slip pattern, sliding groove, and abutting column, it is convenient to fix the nylon rope, with strong resistance, which can prevent the rope end from falling off, and at the same time can prevent the problem that the rope end is stuck in the device and difficult to take out after the test.

A limiting groove is provided on the inner wall of the friction block 96, and the inner wall of the limiting groove is slidably connected to the inner wall of the limiting strip.

[0028] Working principle: By rotating the fixing bolt 98, removing the fixing block 97, and replacing the friction block 96 with different friction coefficients, one end of the three composite ropes 10 is fixed by the fixing rope clip 2. Then, the three composite ropes 10 are passed through the frame body 6, and the other end of the composite ropes 10 is fixed by the movable rope clip 5. According to the rain situation at the place where the composite ropes 10 are used, acid-base solution is added to the water tank 71. By starting the driving motor 79 to drive the first crown gear 710 to rotate, the face gear 711 is driven to rotate. The rotation of the face gear 711 drives the rotating cylinder 75 to rotate, thereby driving the water outlet pipe 76 to rotate. By starting the water pump 72, the acid-base solution in the water tank 71 enters the gap between the fixed cylinder 78 and the rotating cylinder 75 through the connecting pipe 73. Mechanical seals are used to prevent the leakage of the acid-base solution. The acid-base solution enters the water outlet pipe 76 through the through hole 77 and is then sprayed onto the composite ropes 10 through the water outlet pipe 76 to simulate the rain situation at the place of use. At the same time, when the rotating cylinder 75 rotates, it drives the connecting block 85 to move through the surrounding groove 81, and drives the slider 84 to reciprocate under the action of the sliding rod 83, thereby driving the heating ring 86 to move outside the composite ropes 10 to heat the composite ropes 10, so as to simulate the temperature situation at the place of use. When the face gear 711 rotates, it drives the second crown gear 92 to rotate, thereby driving the first rotating rod 91 to rotate. The rotation of the first rotating rod 91 drives the second rotating rod 94 to rotate through the transmission 93, and further drives the friction block 96 on the fixed seat 95 to rotate, rubbing the composite ropes 10, so as to simulate the influence of the wear generated by the contact of the composite ropes 10 with different materials, such as pulley, drum and other materials, on the tensile force. By starting the telescopic hydraulic cylinder 3 to drive the tensile force sensor to move, the tensile force sensor drives the moving plate 4 to move, thereby driving the movable rope clip 5 to move to conduct a tensile force test on the composite ropes 10. By the difference values on the three tensile force sensors, the influence of different environments on the tensile force value of the same composite ropes 10 is judged to ensure that the composite ropes 10 can better adapt to the use in different environments.

[0029] It should be noted that the mechanical seal mentioned in this application is composed of structures such as a dynamic ring, a static ring, a sealing ring, and a spring, which is a relatively mature existing technology. Therefore, this application does not make redundant introductions and is only used for sealing between the rotating cylinder 75 and the fixed cylinder 78.

[0030] The present invention provides a tensile force test device for the production of composite ropes. There are many methods and ways to specifically implement this technical solution. The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. Each component not clearly defined in this embodiment can be implemented by using existing technologies.
