TECHNICAL FIELD
[0001] The utility model belongs to tension test technical field, especially relate to a steel wire rope tension test device. BACKGROUND
[0002] Steel wire ropes are widely used in construction, mining, shipping, elevators and other industries, and they usually bear important load tasks, and their safety is directly related to the safety of personnel and property. With the development of industry and the progress of technology, the strength, durability and safety of steel wire ropes are increasingly demanding.
[0003] Traditional tension tests mainly focus on measuring the maximum breaking strength of steel wire ropes, which can only provide performance data under extreme conditions. However, in practical applications, steel wire ropes also need to withstand repeated loads, bending and twisting and other complex stresses, so relying solely on single tensile testing cannot fully assess their durability and reliability.
[0004] Therefore, the above situation needs to be solved. INVENTION CONTENT
[0005] The utility model aims at overcoming the above-mentioned defects, and provides a rubber tension testing machine, which can test the tension effect of steel wire ropes after bearing complex stress, improve the comprehensiveness and accuracy of testing, and better understand the actual performance of steel wire ropes.
[0006] Technical scheme: a steel wire rope tension test device, comprising a cylinder assembly, a first steel wire rope clamp, a second steel wire rope clamp, a gear assembly, a first sliding mechanism and a second sliding mechanism; the cylinder assembly is connected to the first steel wire rope clamp, and the second steel wire rope clamp is arranged correspondingly with the first steel wire rope clamp; the gear assembly is arranged between the first steel wire rope clamp and the second steel wire rope clamp; the first sliding mechanism and the second sliding mechanism are arranged on a work platform; the gear assembly is slidably connected with the first sliding mechanism; and the second steel wire rope clamp is slidably connected with the second sliding mechanism. The present application can simulate various complex stress environments that steel wire ropes may encounter in actual use, and can more realistically reflect the performance of steel wire ropes under different working conditions, thereby providing more comprehensive performance evaluation.
[0007] Further, the first steel wire rope clamp and the second steel wire rope clamp each include a pressing piece, a bracket, a first sleeve rod, a second sleeve rod, and a set of clamp fasteners; the pressing piece is movably arranged on the top of the bracket, the first sleeve rod and the second sleeve rod are respectively sleeved on the two sides of the bracket, and are fixed by the clamp fasteners. The steel wire rope clamp of the present application has a simple structure and is easy to disassemble and install. The first sleeve rod and the second sleeve rod are firmly fixed on the bracket by using the clamp fasteners, which can ensure the stability of the entire clamp structure. This design enables the clamp to withstand a larger tensile force without displacement or loosening, thereby ensuring the reliability during the test process.
[0008] Further, the first sleeve rod and the second sleeve rod are connected with the steel wire rope, and the second sleeve rod is screwed with the end of the steel wire rope on the first sleeve rod. The present application creates a more secure and reliable connection point by screwing the second sleeve rod with the end of the steel wire rope on the first sleeve rod. This design reduces the risk of slipping or breaking that may occur during high-tension testing, ensuring the safety of the testing process and the accuracy of the results.
[0009] Further, the steel wire rope is wound on the first sleeve rod and the second sleeve rod, and covers the end thereof. The present application can significantly enhance the fixing effect of the steel wire rope by winding the steel wire rope directly on the first sleeve rod and the second sleeve rod, and covering the end thereof. The winding method helps to more evenly distribute the tensile force applied on the steel wire rope. Compared with simple end fixing, winding can disperse stress points and reduce local stress concentration, thereby reducing the risk of steel wire rope breaking and providing more realistic performance test results.
[0010] Further, the pressing piece is arranged opposite to the steel wire rope, and the diameter of the pressing piece is greater than the winding width of the steel wire rope. Since the diameter of the pressing piece is greater than the winding width of the steel wire rope, it means that the pressing piece can more comprehensively cover and apply pressure on the steel wire rope. This design can ensure that the steel wire rope is uniformly stressed throughout the width range, avoiding local stress concentration, thereby enhancing the stability and firmness of the clamp on the steel wire rope.
[0011] Further, the gear assembly includes a gear, and a groove is formed on the gear along a circumference of a wheel shaft; the width of the groove is greater than the diameter of the steel wire rope, and the steel wire rope is arranged in the groove. The present application can ensure that the steel wire rope moves along a predetermined path during the tensile test by arranging a groove on the gear for accommodating the steel wire rope. This design greatly improves the guiding accuracy of the steel wire rope, avoiding the problems of deviation or misalignment that may occur under high stress.
[0012] Further, the gear assembly is provided with at least two sets, and the gear teeth are engaged with each other. The present application can realize more stable transmission process by designing at least two sets of gear assemblies and engaging the gear teeth with each other.
[0013] Further, the first sliding mechanism and the second sliding mechanism each comprise a driving device, a sliding rail and a sliding block. The first sliding mechanism is linear, and the second sliding mechanism is arc-shaped. The present application can simulate more complex curved paths that may occur in real-world application scenarios, and is beneficial to the research on the tensile performance test of the steel wire under the bending condition, by virtue of the arc-shaped design of the second sliding mechanism. In combination with the linear and arc-shaped sliding mechanisms, comprehensive tensile test can be performed.
[0014] Further, transparent protective covers are arranged around the working platform. The transparent protective covers arranged around the working platform can significantly improve the safety of operation and guarantee good visibility.
[0015] The above technical scheme can have the following beneficial effects:
[0016] 1. The present application relates to a steel wire tensile test device, and the sliding mechanism and the gear assembly involved in the present application can ensure that each stress applied to the steel wire can be accurately controlled and measured, thereby improving the accuracy of the test results. Compared with the traditional device that can only measure the maximum breaking strength of the steel wire, the device can more accurately measure the performance of the steel wire under complex stress conditions.
[0017] 2. The present application relates to a steel wire tensile test device. The present application adopts a triple fastening steel wire connecting means, and the second sleeve rod and the end of the steel wire are screwed to the first sleeve rod, so as to create a more secure and reliable connection point. The steel wire is directly wound on the first sleeve rod and the second sleeve rod, and covers the end thereof, so as to significantly enhance the fixing effect of the steel wire. The diameter of the compression piece is greater than the width of the steel wire winding, which means that the compression piece can more comprehensively cover and apply pressure to the steel wire.
[0018] 3. The present application relates to a steel wire tensile test device. The present application can ensure that the steel wire moves along the predetermined path during the tensile test process by providing a groove on the gear for accommodating the steel wire. This design greatly improves the guiding accuracy of the steel wire and avoids the problems of deviation or misplacement that may occur under high stress conditions.
[0019] 4. The present application relates to a steel wire tensile test device. The second sliding mechanism is arc-shaped, which can simulate more complex curved paths that may occur in real-world application scenarios, and is beneficial to the research on the tensile performance test of the steel wire under the bending condition.
