Description

Technical Field

[0001] This application relates to the technical field of round-link chains, and in particular to a tensile test device for round-link chain detection. Background Art

[0002] In modern industrial production, as a key structural component, the round-link chain is widely used in multiple fields such as mines, metallurgy, transportation, etc. The performance and quality of the round-link chain are directly related to the safe operation of equipment and production efficiency. Therefore, it is particularly important to conduct comprehensive and accurate detection on it; the detection of round-link chains usually involves the detection of multiple mechanical properties such as tensile strength, breaking strength, fracture strength, reduction of area, and tensile load to ensure that it has sufficient load-bearing capacity in the actual working environment.

[0003] In the related art, during the detection process of round-link chains, a tensile test device is an indispensable tool; however, in the tensile test link of traditional tensile test devices, since the round-link chain is prone to break when reaching the ultimate tensile force, the fragments or fracture surfaces of the round-link chain may splash instantaneously during the break, which not only damages the test equipment but also poses a safety threat to the operators. The splashing fragments may cause equipment failures, distorted test data, and even pose potential hazards to the life safety of the operators. Therefore, it needs to be improved. Utility Model Content

[0004] In order to solve the problem of easy splashing during tensile test fracture, this application provides a tensile test device for round-link chain detection.

[0005] The tensile test device for round-link chain detection provided by this application adopts the following technical solutions:

[0006] A tensile test device for round-link chain detection includes a workbench, on which a tensile mechanism and a protection mechanism are arranged. The protection mechanism includes an opening and closing baffle and two protection plates. The two protection plates are respectively arranged on both sides of the tensile mechanism, and both protection plates are connected to the workbench. The opening and closing baffle is arranged between the two protection plates, and the opening and closing baffle is located in front of the tensile mechanism. A protection area is formed between the two protection plates and the opening and closing baffle. One end of the opening and closing baffle is rotatably arranged with one of the protection plates, and the other end of the opening and closing baffle is provided with a connection component for connecting with the other protection plate. The connection component includes a socket and a plug. The plug is connected to the opening and closing baffle, an insertion block is arranged at the end of the plug, and a slot for inserting the insertion block is opened on the socket.

[0007] Since the round-link chain is prone to breakage when reaching the ultimate tensile force, the fragments or fracture surfaces of the round-link chain may splash at the moment of fracture. This not only causes damage to the testing equipment, but also poses a safety threat to the operators. The splashing fragments may lead to equipment failures, distorted test data, and even pose potential hazards to the life safety of the operators. By adopting the above technical solution, the tensile mechanism and the protection mechanism are installed on the workbench. The protection mechanism includes an opening and closing baffle and two protection plates. During the round-link chain tensile test, as the tensile force gradually increases, the round-link chain begins to bear an increasing tension. The tester closely monitors the display data on the tensile mechanism and the state changes of the round-link chain. At this time, the protection mechanism on the workbench plays a key role. The protection area formed by the opening and closing baffle and the two protection plates effectively isolates the test area. When the tensile force reaches the limit of the round-link chain, the round-link chain suddenly breaks, making a crisp sound. Due to the protection of the protection mechanism, the fragments or fracture surfaces generated by the fracture are firmly blocked within the protection area and do not splash out. After the test, the tester turns off the tensile mechanism, opens the opening and closing baffle, and the insertion block disengages from the slot and enters the protection area to clean and inspect the test site. Through the settings of the opening and closing baffle, the protection plates and the connection components, the test area can be effectively isolated, and the splashing of the fragments or fracture surfaces generated when the round-link chain breaks is reduced, thus ensuring the safety of the testing equipment and the operators. At the same time, the design of the opening and closing baffle enables the tester to conveniently enter the protection area for cleaning and inspection after the test, improving the work efficiency.

[0008] Optionally, mounting parts are respectively arranged at both ends of the socket, and mounting holes for bolts to pass through are formed in the mounting parts.

[0009] By adopting the above technical solution, the mounting parts are integrally formed on the socket, and the mounting holes are penetratingly formed in the mounting parts. Through the settings of the mounting parts and the mounting holes, the stable connection between the socket and the protection plate is realized, ensuring the stability and reliability of the entire protection mechanism. The installation is convenient, and the installation of the socket and the protection plate can be quickly completed, improving the installation efficiency.

[0010] Optionally, a T-shaped mounting plate for fixing to the workbench is arranged on each protection plate. The protection plate is connected to the vertical end of the T-shaped mounting plate, and the flat end of the T-shaped mounting plate is connected to the workbench.

[0011] By adopting the above technical solution, the protection plate is installed on the workbench through the T-shaped mounting plate. Through the setting of the T-shaped mounting plate, the tester can easily realize the quick installation and disassembly of the protection plate by adjusting the connection between the T-shaped mounting plate and the workbench, which not only improves the work efficiency, but also makes the device more convenient for maintenance and component replacement.

[0012] Optionally, the tensile mechanism includes a power cylinder, a tensile fixture, and a fixed anchor. The fixed anchor is arranged between the two protective plates and is connected to the workbench. The tensile fixture is arranged directly above the fixed anchor, and the power cylinder is arranged on the workbench. The output end of the power cylinder is connected to the tensile fixture.

[0013] By adopting the above technical solution, the tensile mechanism includes a power cylinder, a tensile fixture, and a fixed anchor. When testing the tensile force of the ring chain, place the ring chain to be tested on the fixed anchor to ensure it is firmly fixed on the workbench. Then place the tensile fixture at the other end of the ring chain to ensure that the fixture can firmly grip the ring chain. Subsequently, start the power cylinder. The power cylinder serves as the power source for providing the tensile force, and its output end is connected to the tensile fixture. As the power cylinder starts, it gradually applies a tensile force to the ring chain, simulating the stress situation in actual use. During the test, the tester needs to closely monitor the display data on the tensile mechanism. These data can reflect in real-time the magnitude of the tensile force borne by the ring chain, thereby helping the tester judge the performance and limit of the ring chain. As the tensile force gradually increases, when the tensile force reaches the preset limit of the ring chain or the ring chain breaks, the tester needs to immediately stop the operation of the power cylinder and record the final data on the tensile mechanism. These data are of great significance for evaluating the performance of the ring chain and determining its quality grade. Through the settings of the power cylinder, tensile fixture, and fixed anchor, various stress situations of the ring chain in actual use can be simulated, which helps to achieve efficient, accurate, and safe tensile testing of the ring chain, improving the efficiency and reliability of the test.

[0014] Optionally, a support base is arranged between the tensile fixture and the power cylinder, and rib plates for enhancing the structural strength are arranged on the support base.

[0015] By adopting the above technical solution, the support base is installed between the tensile fixture and the power cylinder, and the rib plates are welded and fixed on the support base. Through the settings of the support base and the rib plates, the support base provides a stable support platform for the tensile fixture, ensuring that during the test, the tensile force can be applied to the ring chain stably and accurately, which helps to reduce errors caused by unstable support and improve the accuracy of the test. At the same time, as a key component for enhancing the structural strength, the rib plates significantly improve the bearing capacity and anti-deformation ability of the support base.

[0016] Optionally, guide rods are arranged on the workbench. The guide rods are arranged along the running direction of the tensile fixture, and the support base is slidably connected to the guide rods.

[0017] By adopting the above technical solution, the guide rod is vertically installed on the workbench, and the support seat is slidably connected to the guide rod; through the setting of the guide rod, it has a positioning and guiding function, ensuring that the tension clamp can move along a predetermined and stable path when the tension is applied, reducing the test error caused by offset or shaking.

[0018] Optionally, the workbench is further provided with two stroke limiting blocks for controlling the stroke of the tension clamp, and the two stroke limiting blocks are arranged opposite to each other along the running direction of the tension clamp.

[0019] By adopting the above technical solution, two stroke limit blocks are installed on the workbench; through the setting of the two stroke limit blocks, the main function of the stroke limit blocks is to limit the stroke range of the tension clamp, ensuring that it moves within the preset track, which helps to prevent the clamp from exceeding the safety range during the test, causing equipment damage or inaccurate testing, while improving the safety of the test process.

[0020] Optionally, an adjustment plate is provided on each of the travel limiting blocks, a strip hole is formed through the adjustment plate, a plurality of through holes for installing the adjustment plate are formed on the workbench, and the plurality of through holes are arranged along the height direction of the workbench.

[0021] By adopting the above technical solution, the adjustment plate is installed on the stroke limiting block, and the adjustment plate realizes the change of the position of the stroke limiting block through the bar holes corresponding to the through holes in different positions; through the setting of the adjustment plate, the bar holes and the through holes, the operator can quickly and accurately adjust the stroke range of the tension clamp according to actual needs to meet the needs of different testing or production scenarios, with good flexibility and adaptability.

[0032] The following will Figures 1-5 further elaborate on the present application in conjunction with the attached

[0033] The embodiment of the present application discloses a tensile test device for ring chain detection.

[0035] Referring toFigure 1 , the opening and closing baffle 31 is installed between the two protective plates 32. A handle for gripping is installed on the opening and closing baffle 31. In this embodiment, a protective area is formed between the opening and closing baffle 31 and the two protective plates 32. The protective area effectively isolates the test area and plays a protective role when the round-link chain suddenly breaks when the pulling force reaches the limit of the round-link chain.

[0036] Refer to Figure 1 and Figure 3 , one end of the opening and closing baffle 31 is rotatably installed on one of the protective plates 32. In this embodiment, the opening and closing baffle 31 can be rotatably installed through a hinge structure.

[0037] Refer to Figure 1 and Figure 4 , mounting parts 5 are integrally formed at both ends of the socket 41. The mounting parts 5 are attached to the corresponding protective plate 32. Mounting holes 51 are formed through the mounting parts 5. The socket 41 can be installed on the protective plate 32 by passing fixing parts such as bolts through the mounting holes 51.

[0038] Refer to Figure 1 and Figure 4 , the plug 42 is installed and fixed on the opening and closing baffle 31. The plug 42 corresponds to the socket 41. A plug block 421 is integrally formed on the plug 42. A slot 411 is formed in the socket 41. The plug block 421 is inserted and fixed in the slot 411. In this embodiment, the number of the plug blocks 421 can be multiple groups.

[0039] Refer to Figure 1 , the pulling force mechanism 2 includes a power cylinder 21, a pulling force clamp 22 and a fixed anchor 23. The fixed anchor 23 is installed on the workbench 1. The fixed anchor 23 is located between the two protective plates 32. One end of the round-link chain is fixed on the fixed anchor 23. The pulling force clamp 22 is installed directly above the fixed anchor 23. The pulling force clamp 22 is connected to the other end of the round-link chain. The power cylinder 21 is installed on the workbench 1. A support seat 7 is installed at the output end of the power cylinder 21. The pulling force clamp 22 is installed on the support seat 7. In this embodiment, a corresponding pulling force sensor is provided in the pulling force mechanism 2. The pulling force sensor is usually installed on the power transmission path of the pulling force mechanism 2 for real-time monitoring and measurement of the magnitude of the pulling force.

[0040] Refer to Figure 5 , a rib plate 71 is welded and fixed on the support seat 7. The rib plate 71, as a key component for enhancing the structural strength, significantly improves the bearing capacity and anti-deformation ability of the support seat 7.

[0041] Refer to Figure 5, a guide rod 8 is vertically installed on the workbench 1. In this embodiment, the number of guide rods 8 is two, and the two guide rods 8 are symmetrically installed on both sides of the support base 7, and the support base 7 is slidably connected to the two guide rods 8; to achieve the positioning and guiding function, ensuring that the tensile fixture 22 can move along a predetermined and stable path when applying tensile force, reducing the test error caused by deviation or shaking.

[0042] Referring to Figure 5 , two stroke limit blocks 9 are installed on the frame of the workbench 1. The two stroke limit blocks 9 are arranged oppositely along the running direction of the tensile fixture 22. The range between the two stroke limit blocks 9 is the stroke range of the tensile fixture 22. The support base 7 corresponds to the two stroke limit blocks 9, ensuring that it moves within the preset track, which helps to avoid the fixture exceeding the safety range during the test, resulting in equipment damage or inaccurate testing.

[0043] Referring to Figure 5 , an adjusting plate 10 is fixedly installed on each stroke limit block 9. A strip-shaped hole 101 is penetrated through the adjusting plate 10. A number of through holes 11 are opened on the frame of the workbench 1. The number of through holes 11 are sequentially opened along the height direction of the workbench 1 frame. The adjusting plate 10 realizes the change of the position of the stroke limit block 9 by corresponding the strip-shaped hole 101 to the through holes 11 at different positions, allowing the operator to quickly and accurately adjust the stroke range of the tensile fixture 22 according to actual needs to meet the requirements of different test or production scenarios, with good flexibility and adaptability.

[0044] The implementation principle of a tensile test device for ring chain detection in an embodiment of this application is as follows: during the ring chain tensile test, the ring chain to be tested is placed on the fixed anchor 23 to ensure it is firmly fixed on the workbench 1. Then, the tensile fixture 22 is placed at the other end of the ring chain to ensure that the fixture can firmly hold the ring chain. Subsequently, the power cylinder 21 is started. The power cylinder 21 serves as the power source for providing tensile force, and its output end is connected to the tensile fixture 22. As the power cylinder 21 is started, it gradually applies tensile force to the ring chain, simulating the stress situation in actual use. During the test, the tester needs to closely monitor the display data on the tensile mechanism 2, and these data can reflect the tensile force magnitude borne by the ring chain in real time, thereby helping the tester judge the performance and limit of the ring chain;

[0045] As the pulling force gradually increases, when the pulling force reaches the preset limit of the ring chain or the ring chain breaks, the protection mechanism 3 on the workbench 1 plays a key role at this time. The protection area formed by the opening and closing baffle 31 and the two protection plates 32 effectively isolates the test area. When the ring chain suddenly breaks, a clear sound is made. Due to the protection of the protection mechanism 3, the fragments or fractures generated by the break are firmly blocked within the protection area and do not fly out. After the test, the tester turns off the pulling force mechanism 2, opens the opening and closing baffle 31, and the insertion block 421 disengages from the slot 411 and enters the protection area to clean and inspect the test site. Through the settings of the opening and closing baffle 31, the protection plate 32 and the connection component 4, the test area can be effectively isolated, and the splashing of fragments or fractures generated when the ring chain breaks is reduced, thus ensuring the safety of the test equipment and the operator. At the same time, the design of the opening and closing baffle 31 enables the tester to conveniently enter the protection area for cleaning and inspection after the test, improving the work efficiency.

[0046] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
