Description

Technical Field

[0001] This utility model relates to the field of testing machine technology, and in particular to a chain tensile testing device. Background Technology

[0002] Chain tensile testing is a crucial step in ensuring the safe use of chains and is widely applied in various fields requiring chain drive or load-bearing. Existing chain tensile testing equipment suffers from several problems in practical applications: In terms of assembly and disassembly, traditional devices rely heavily on bolt fastening or complex transmission structures to secure the chain, resulting in cumbersome operation and multiple adjustments required for each test, severely impacting testing efficiency and making them unsuitable for batch testing. Regarding structural strength, the cross braces supporting the chain lack effective reinforcement design, making them prone to deformation under prolonged tensile stress, affecting testing accuracy and shortening equipment lifespan. In terms of safety, the limiting measures in existing devices are unreliable, allowing the chain to easily shift laterally or even detach during the tensile process. Furthermore, some devices lack anti-detachment structures, further increasing safety hazards during testing.

[0003] Therefore, a testing device is needed that can enable rapid loading and unloading of chains, has high-strength support, and reliable limiting, in order to overcome the shortcomings of existing technologies. Utility Model Content

[0015] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0016] Example 1 See Figures 1 to 6 A chain tensile strength testing device includes a clamping block 1 and a clamping part 2, wherein the clamping part 2 is disposed on the top of the clamping block 1; it also includes a placement groove 3, wherein the placement groove 3 is disposed on the clamping block 1, and a cross brace 4 is disposed at the lower part of the placement groove 3, wherein a through hole 42 is disposed on the cross brace 4.

[0017] like Figures 1 to 6 As shown, a reinforcing hoop 41 is provided below the cross brace 4.

[0018] like Figures 3 to 6 As shown, it also includes a limiting component.

[0019] like Figure 5 and Figure 6 As shown, the limiting component includes a crossbar 5 and a limiting groove 6. The limiting groove 6 is disposed on one side of the placement groove 3 along its length. The crossbar 5 is rotatably connected to the other side of the limiting groove 6 along its length via a rotating shaft 7. The free end of the crossbar 5 is placed in the limiting groove 6.

[0020] like Figure 3 and Figure 4 As shown, the limiting component includes a crossbar 5 and a limiting groove 6. The limiting groove 6 is disposed on both sides of the placement groove 3 along its length, and the crossbar 5 is placed on the two limiting grooves 6.

[0021] like Figure 3 and Figure 4 As shown, a stop block 61 is provided at the end of the limiting groove 6 away from the placement groove 3.

[0022] like Figures 1 to 6 As shown, the cross brace 4 is provided with a recessed portion 43.

[0023] Working principle This invention achieves efficient and safe chain tensile testing through optimized structural design. The placement groove 3 provides positioning space for the chain, and the cross brace 4 connects to the chain end via a through hole 42, bearing the tensile force during testing. The reinforcing hoop 41 enhances the cross brace 4's resistance to deformation, ensuring stable support strength over long-term use. The limiting component, through the cooperation of the cross bar 5 and the limiting groove 6, constrains the chain's lateral displacement during the stretching process, preventing it from falling off. The stop block 61 further prevents the cross bar 5 from accidentally detaching, improving safety. The recessed portion 43 on the cross brace 4 guides the chain to center, reducing the risk of lateral deviation. The clamping part 2 connects to an external tensile testing device, transmitting the tensile force to the chain through the clamping block 1 to complete the tensile performance test.

[0024] In the first type of limiting component, the limiting groove 6 is located on one side of the placement groove 3 along its length, and the crossbar 5 is rotatably connected to the other side of the limiting groove 6 along its length via a rotating shaft 7. During testing, rotating the crossbar 5 causes its free end to fall into the limiting groove 6, forming a lateral constraint on the chain and preventing chain deviation. Furthermore, the rotating shaft 7 is designed for quick opening and closing, improving operational convenience.

[0025] In the second type of limiting assembly, limiting grooves 6 are respectively located on both sides of the placement groove 3 along its length, and the crossbar 5 is placed directly on the two limiting grooves 6. Through the cooperation of the crossbar 5 and the limiting grooves 6 on both sides, a stable limit is formed from both sides of the chain to prevent lateral disengagement. The end of the limiting groove 6 is provided with a stop 61, which can further prevent the crossbar 5 from slipping off during the test and enhance safety.

[0026] Detailed operating procedures Adjust the chain according to the specifications. If a limiting assembly with a pivot 7 is used, flip the crossbar 5 to disengage it from the limiting groove 6; if it is a double limiting groove 6 structure, remove the crossbar 5.

[0027] Place the end of the chain into the placement groove 3, aligning the chain with the through hole 42 of the cross brace 4, ensuring that the chain fits against the surface of the cross brace 4. If there is a recess 43, place the chain in the center of the recess.

[0028] For the pivot-type limiting assembly, rotate the crossbar 5 so that its free end falls into the limiting groove 6; for the double limiting groove 6 structure, place the crossbar 5 on both sides of the limiting groove 6, ensuring that the crossbar 5 is in contact with the top of the chain. If there is a limiting groove 6 stop 61, after placement, both ends of the crossbar 5 should contact the stop 61 to prevent slippage.

[0029] The device is fixed to the tensile testing equipment by clamping part 2, and the connection parts are checked to ensure that they are secure.

[0030] Start the tensioning equipment, apply tension to the preset value, and monitor the chain status and test data in real time.

[0031] Stop the tensioning equipment and wait for the device to reset. Then, release the limiting component (flip or remove the crossbar 5), take the chain out of the placement slot 3, and complete the test.

[0032] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not a limitation on the scope of protection of the present utility model. Based on the technical solution of the present utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the present utility model.
