[0031] A moving mechanism, movably mounted inside the slotted fixed block 2;
[0032] The protection mechanism is fixedly mounted on the front of the rectangular block 9 and is fixedly connected to the moving mechanism;
[0033] Among them, the protection mechanism includes an L-shaped protection plate 1 8 fixedly installed on the front of the moving block 6, and an L-shaped protection plate 2 10 is fixedly installed on the front of the rectangular block 9, and the L-shaped protection plate 2 10 is slidably connected to the L-shaped protection plate 1 8.
[0034] By arranging the L-shaped protective plate 2 10 and the L-shaped protective plate 1 8, the design of the L-shaped protective plate 1 enables it to fit tightly on the moving block, and the L-shaped protective plate 1 8 moves with the movement of the moving block 6, so as to always remain in the position where protection is required, which not only ensures the continuity and effectiveness of the protection, but also improves the structural stability of the entire clamp, and it is connected by a sliding connection, so that it can move within a certain range to adapt to different lengths of wire ropes or different test requirements, which not only improves the adaptability of the clamp, but also makes it more convenient and quick for the operator to install and remove the protective mechanism. Compared with traditional devices, when the wire rope tensile testing machine is working, the L-shaped protective plate 1 and the L-shaped protective plate 2 together form a protective barrier, which effectively prevents the fragments or broken parts splashed due to the breakage of the wire rope from causing damage to the operator or equipment, and at the same time, they can also prevent other external objects from entering the inside of the clamp to ensure the accuracy and safety of the test.
[0035] When preparing for the tension test, the staff first starts the motor 4. The output shaft of the motor 4 drives the threaded rod 5 to rotate, and the threaded rod 5 drives the moving block 6 to move in the vertical direction, thereby realizing the precise stretching operation of the wire rope. At the same time, the movement of the moving block 6 drives the L-shaped protective plate 8 to move together, and a protective barrier is formed by the L-shaped protective plate 18 and the L-shaped protective plate 2 10, which effectively prevents the fragments or broken parts splashed out due to the breakage of the wire rope from causing damage to the operator or equipment.
[0036] Among them, a clamp 11 is slidably installed on the front of the moving block 6.
[0037] The upper clamping mechanism is arranged inside the clamp 11;
[0038] A lower clamping mechanism is slidably mounted on the top of the rectangular block 9;

The two clamping blocks 14 are fixedly installed with threaded rods 13 on the sides away from each other.

[0040] By rotating the two handles 15, the two handles 15 drive the two clamps 11 to approach each other, and the two clamps 11 respectively drive the two clamping blocks 14 to move, so as to clamp or release the wire rope. Compared with the traditional device, by setting the handle 15, the operator can have a stable gripping point when rotating the threaded rod 2 13 to clamp or release, which improves the convenience and stability of the operation. The traditional holding mechanism may lack such a design, making the operation process relatively cumbersome and difficult to control. The clamping block 14 can be slidably adjusted in the clamping movable groove 12 to adapt to steel wires with different diameters or different clamping requirements. It has stronger adaptability and can cope with a variety of different test scenarios.
[0041] The staff first wraps one end of the steel wire rope to be tested around the outer wall of the fixed column 16, and then rotates the two handles 15. The two handles 15 drive the two clamps 11 to approach each other, and the two clamps 11 respectively drive the two clamping blocks 14 to move, thereby firmly clamping the rope head and rope body of the steel wire rope. Then, the end of the steel wire rope is placed on the side where the clamp 2 17 and the clamping block 20 are close to each other, and then the handle 21 is rotated to push the clamping block 20 to move in the clamping movable groove 2 18, so that the end of the steel wire rope is also firmly clamped.
[0042] Among them, the moving mechanism includes a partition 3 fixedly installed in the grooved fixed block 2, a motor 4 is fixedly installed on the top of the base 1, a threaded rod 5 is rotatably installed in the grooved fixed block 2, the bottom end of the threaded rod 5 passes through the partition 3, the output shaft of the motor 4 is fixedly connected to the bottom end of the threaded rod 5, and the outer wall of the threaded rod 5 is threadedly connected to the moving block 6.
[0043] By starting the motor 4, the output shaft of the motor 4 drives the threaded rod 5 to rotate, and the threaded rod 5 drives the moving block 6 to move in the vertical direction, thereby realizing the precise stretching and release of the wire rope, and is an important component of the wire rope tension testing machine fixture.
[0044] Among them, a limiting slide bar 7 is fixedly installed on the inner wall of the grooved fixed block 2, the bottom end of the limiting slide bar 7 is fixedly connected to the top of the partition 3, and the limiting slide bar 7 passes through the moving block 6 and is slidably connected to the moving block 6.
[0045] By providing the limiting slide bar 7, the moving block 6 can move smoothly and accurately along the limiting slide bar 7, thereby improving the stability and safety of the device.

[0047] By setting up the lower clamping mechanism and rotating the second handle 21, the second clamping block 20 is pushed to move in the second clamping movable groove 18, so as to achieve a stable support for the wire rope. The design is not only easy to operate, but also improves the applicability of the device.
[0048] Among them, two limit blocks 23 are fixedly installed on the side of the L-shaped protective plate 1 8, and two limit grooves 24 are opened on the inner wall of the L-shaped protective plate 2 10, and the two limit blocks 23 are adapted to the corresponding limit grooves 24.
[0049] By installing two limit blocks 23, the functions of positioning and fixing are provided to prevent unnecessary movement or misalignment between the L-shaped protective plate 1 8 and the L-shaped protective plate 2 10. By setting two limit grooves 24, it is ensured that the two limit blocks 23 can be stably embedded therein, thereby enhancing the connection stability between the L-shaped protective plate 1 and the L-shaped protective plate 2.
[0050] A tooth groove 22 is respectively formed on one side of the two clamping blocks 14 that are close to each other, and a fixing column 16 is fixedly installed on the inner wall of the back side of the clamping movable groove 12 .
[0051] By providing the tooth grooves 22, the friction between the two clamping blocks 14 and the steel wire rope is increased to ensure that when tension is applied, the steel wire rope can be stably and firmly clamped to prevent it from sliding or falling off, which helps to improve the accuracy and reliability of the tension test. Through the fixed column 16, when the steel wire rope is supported, it is first wrapped around the outer wall of the fixed column 16 and then passed through the two clamping blocks 14, which further enhances the fixing effect of the clamp on the steel wire rope.

[0053] When preparing for the tension test, the staff first starts the motor 4. The output shaft of the motor 4 drives the threaded rod 5 to rotate, and the threaded rod 5 drives the moving block 6 to move in the vertical direction, thereby realizing the precise stretching operation of the wire rope. At the same time, the movement of the moving block 6 drives the L-shaped protective plate 8 to move together, and a protective barrier is formed by the L-shaped protective plate 18 and the L-shaped protective plate 2 10, which effectively prevents the fragments or broken parts splashed out due to the breakage of the wire rope from causing damage to the operator or equipment.
[0054] The staff first wraps one end of the steel wire rope to be tested around the outer wall of the fixed column 16, and then rotates the two handles 15. The two handles 15 drive the two clamps 11 to approach each other, and the two clamps 11 respectively drive the two clamping blocks 14 to move, thereby firmly clamping the rope head and rope body of the steel wire rope. Then, the end of the steel wire rope is placed on the side where the clamp 2 17 and the clamping block 20 are close to each other, and then the handle 21 is rotated to push the clamping block 20 to move in the clamping movable groove 2 18, so that the end of the steel wire rope is also firmly clamped.
