Description

Technical Field

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

[0002] Horizontal tensile testing machines are crucial equipment for evaluating the breaking strength and safety performance of webbing (such as lifting slings and binding straps). They typically consist of a guide rail with two sliding platforms mounted on it. During testing, one platform (fixed end) is locked in a specific hole on the guide rail by inserting a metal retaining pin (often weighing up to 50 catties); the other platform (drive end) is connected to a screw drive system, responsible for applying and measuring the tensile force. However, in actual use, because different lengths of webbing need to be tested, operators must frequently adjust the position of the fixed-end platform on the several-meter-long guide rail. Each adjustment requires using a crane or gantry crane used for heavy material handling in the workshop to lift the retaining pin, push the platform to the new position, and finally lift the retaining pin to insert it into the corresponding positioning hole. This method of lifting not only wastes valuable lifting equipment but also occupies critical lifting equipment intended for production, severely impacting the normal production process. Utility Model Content

[0015] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0016] Please refer to Figure 1 and Figure 2 As shown, this utility model discloses a tensile testing machine, including a testing machine body 1 and a hoisting device located on one side of the testing machine body 1. The hoisting device includes a transfer trolley 2, a hanger 3, and a first guide rail 4. The transfer trolley 2 is slidably mounted on the first guide rail 4. The hanger 3 is mounted on the transfer trolley 2 and is equipped with a winch 31 and a fixed pulley 32. The first guide rail 4 is laid along the length of the testing machine body 1 on one side of the testing machine body 1, and the fixed pulley 32 is located above the testing machine body 1.

[0017] Working principle: A transfer trolley 2 equipped with a lifting frame 3 is added to one side of the testing machine body 1. During operation, the winch 31 on the lifting frame 3 winds up and unwinds the wire rope, guiding the hook to rise and fall through the fixed pulley 32, thereby pulling the fixing pin off the guide rail of the testing machine body 1. Then, the operator can move the slide (fixed end) of the testing machine body 1 to a new fixed point. Next, the transfer trolley 2 moves along the first guide rail 4 to transfer the fixing pin to the corresponding positioning hole, and re-fixes the slide (fixed end) on the rail. This eliminates the dependence on the workshop overhead crane.

[0018] It is worth noting that the moving speed of the transfer trolley 2 is controlled between 0.3 m / s and 0.8 m / s during the movement. The transfer trolley 2 can be in the form of a handcart or a motor-driven mechanism. The first guide rail 4 is fixed to the ground by bolts or expansion bolts.

[0019] Please refer to Figure 2 As shown, the hanger 3 includes a column 33 and a rod 34. One end of the column 33 is connected to the transfer trolley 2, and the other end of the column 33 is connected to the rod 34. The fixed pulley 32 is mounted on the rod 34.

[0020] In some implementations, please refer to Figure 3 As shown, the first guide rail 4 includes two parallel and spaced steel bars, and grooves 41 are formed on the opposite side surfaces of the two steel bars; a pulley 21 is installed at the bottom of the transfer trolley 2, and the pulley 21 is slidably disposed in the groove 41. The transfer trolley 2 rolls by placing the pulley 21 in the groove 41 to ensure the direction of movement of the transfer trolley 2.

[0021] In some implementations, please refer to Figure 4As shown, the tensile testing machine also includes limiting blocks 5, which are detachably mounted at both ends of the first guide rail 4 along its length. The limiting blocks 5 restrict movement at both ends of the first guide rail 4 along its length to prevent the transfer trolley 2 from overtraveling.

[0022] It is worth noting that the limiting block 5 is fixed to the ground with bolts. When derailment maintenance is required, the transfer trolley 2 can be moved out of the first guide rail 4 by removing the limiting block 5.

[0023] In some implementations, please refer to Figure 1 As shown, a protective cover 6 is slidably mounted on the test machine body 1 along its length. During the tensile test, the webbing will break at the moment it is pulled apart, and will be thrown out of the test machine body 1. Therefore, the protective cover 6 is used to cover the webbing to ensure safe testing. Of course, during the actual testing process, relevant personnel should avoid approaching the test machine body 1.

[0024] In some implementations, please refer to Figure 5 As shown, the protective cover 6 includes a metal grid cage 61 and a metal plate 62, with the metal plate 62 disposed on the outer side wall of the metal grid cage 61. The protective effect is improved by the cooperation of the metal grid cage 61 and the metal plate 62.

[0025] It is worth noting that the thickness of the metal plate 62 is 1.5mm to 3mm. The metal grid cage 61 and the metal plate 62 are made of high-strength metals such as steel and iron. Alternatively, a hemp rope net can be placed over the metal plate 62 to further improve the protective effect.

[0026] In some implementations, please refer to Figure 5 and Figure 6 As shown, the testing machine body 1 is provided with a second guide rail 11, and the protective cover 6 is slidably mounted on the second guide rail 11. The second guide rail 11 guides the movement direction of the protective cover 6.

[0027] In some implementations, please refer to Figure 5 As shown, the second guide rail 11 includes two parallel and spaced steel bars, and the protective cover 6 is provided with a slider 63 that is slidably disposed between the two steel bars. The protective cover 6 moves smoothly on the testing machine body 1 by sliding between the two parallel and spaced steel bars via the slider 63.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
