The traction force test requires the use of a bending wheel to limit the traction. Different cables require different bending wheels for limiting, so the bending wheel needs to be changed frequently to test cables of different specifications.

[0012] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0013] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 A bending wheel replacement device includes a frame 1, and further includes a quick-change device 2 and a testing mechanism 3. The testing mechanism 3 is installed on the upper side of the frame 1, and the quick-change device 2 is located on the right side of the frame 1. The quick-change device 2 includes a polygonal frame 21, a gearbox 22, a first reduction motor 23, and a rotating spindle 24. The polygonal frame 21 is located on the right side of the frame 1. The outer shell of the gearbox 22 is fixedly installed on the middle side of the polygonal frame 21. The first reduction motor 23 is fixedly installed on the outer shell of the gearbox 22. The output shaft of the first reduction motor 23 is fixedly connected to the input end of the gearbox 22. The rotating spindle 24 is fixedly installed on the output end of the gearbox 22, and a rotating frame 25 is fixedly installed on the rotating spindle 24.

[0014] The quick-change device 2 further includes a rotating component, which is installed in a circumferential array at equal intervals on the side of the rotating frame 25.

[0015] The rotating assembly includes an extension plate 26 and a limiting strip 27. The two extension plates 26 are fixedly mounted on the rotating frame 25, and the limiting strip 27 is fixedly mounted on the extension plate 26. The extension plate 26 has an arc-shaped slot 28 for accommodating the shaft of the lower bending wheel 34.

[0016] The quick-change device 2 further includes a flip-lifting assembly, which is installed on the left side of the polygonal frame 21. The flip-lifting assembly includes a flip bar 29, a second reduction motor 210, and a limiting plate 211. The flip bar 29 is rotatably connected to the left side of the polygonal frame 21 via a rotating shaft. The second reduction motor 210 is fixedly installed on the left side of the polygonal frame 21, and the output shaft of the second reduction motor 210 is fixedly connected to the rotating shaft of the flip bar 29. The limiting plate 211 is fixedly installed on the upper side of the flip bar 29. The flip bar 29 is a telescopic rod that can be extended and retracted.

[0017] When the bending wheel needs to be replaced, the output shaft of the first reduction motor 23 of the testing mechanism 3 rotates, causing the input end of the gearbox 22 to rotate. The rotation of the input end of the gearbox 22 causes the output end of the gearbox 22 to rotate. The rotation of the output end of the gearbox 22 causes the rotating main shaft 24 to rotate. The rotation of the rotating main shaft 24 causes the rotating frame 25 to rotate. The rotation of the rotating frame 25 causes the extension plate 26 and the limiting strip 27 to rotate. When the arc-shaped slot 28 of the extension plate 26 is empty, the extension plate 26 is rotated to the left side of the polygonal frame 21. The bearing seat 33 is removed. The output shaft of the second reduction motor 210 of the flipping lifting assembly rotates, causing the flipping strip 29 and the limiting plate 211 to rotate. The flipping strip 29 rotates to the lower bending wheel 34 in the left frame 1. The flipping strip 29 extends. The rotation of the flipping strip 29 causes the lower bending wheel 34 in the left frame 1 to be lifted, so that the lower bending wheel 34 rolls along the flipping strip 29 into the arc-shaped slot 28 of the extension plate 26. The limiting plate 211 limits the front and rear positions of the lower bending wheel 34.

[0018] The rotation of the output shaft of the first geared motor 23 drives the input end of the gearbox 22 to rotate. The rotation of the input end of the gearbox 22 causes the output end of the gearbox 22 to rotate. The rotation of the output end of the gearbox 22 drives the rotating main shaft 24 to rotate. The rotation of the rotating main shaft 24 drives the rotating frame 25 to rotate. The rotation of the rotating frame 25 drives the extension plate 26 and the limiting strip 27 to rotate. The extension plate 26 on the lower side of the lower bending wheel 34 to be replaced rotates to the left side of the polygonal frame 21. The rotation of the output shaft of the second geared motor 210 drives the flipping strip 29 to rotate. The right side of the flipping strip 29 rotates to lift the lower bending wheel 34 to be replaced from the arc-shaped slot 28 and rotates it on the flipping strip 29 into the bearing seat 33. After installing the bearing seat 33, the quick replacement of the lower bending wheel 34 can be completed.

[0019] Example 2: In some embodiments, such as Figures 1-5 In a preferred embodiment of the present invention, the testing mechanism 3 includes: an upper bending wheel 31, a bracket 32, a bearing seat 33, and a lower bending wheel 34.

The bearing seat 33 is fixedly installed on the bracket 32. The lower bending wheel 34 is rotatably connected to the bearing seat 33 via a rotating shaft.

[0020] The upper bending wheel 31 and the lower bending wheel 34 are both slidably connected to the cable to be tested, and the two ends of the cable to be tested are fixedly connected together by the connecting clamp 35.

[0021] The upper bending wheel 31 and the lower bending wheel 34 are used to support the cable under test. The bracket 32 ​​moves up and down on the frame 1, which drives the bearing seat 33 and the lower bending wheel 34 to move up and down. The lower bending wheel 34 moves away from the upper bending wheel 31, causing the cable to be stretched. The bending of the cable under test is observed.
