[0026] A fixing plate 13 is fixedly connected to the top of the first slide plate 4 , and a guide slot 14 is provided on the fixing plate 13 . A guide rod 15 is fixedly connected to each of the second clamping plates 12 , and the guide rod 15 is slidably connected to the guide slot 14 .

[0027] When the above scheme is put into actual use, the staff will respectively put the two ends of the sling into the sleeve rod 3, and make the sling between the first roller 7 and the second roller 8. When testing, under the action of the first spring 10, the second roller 8 will press the sling against the first roller 7, and then start the first driving assembly, so that the first driving assembly drives the second slide plate 5 on the first slide plate 4 to move forward. Figure 1 As shown in the figure, the second slide plate 5 will drive the first roller 7, the second roller 8, the first clamping plate 11 and the second clamping plate 12 to move synchronously through the C-shaped mounting plate 6; the second clamping plate 12 will drive the guide rod 15 to slide in the guide slot 14; Figure 3As shown, the guide rod 15 will first move obliquely upward in the guide slot 14, then move horizontally, then move obliquely downward, and then move horizontally, and the height of the oblique downward movement is greater than the height of the oblique upward movement, and the guide rod 15 will drive the second clamping plate 12 and the second roller 8 to move upward first while moving backward, so that the first roller 7 and the second roller 8 cancel the clamping of the sling, and then the first clamping plate 11 and the second clamping plate 12 will be in an open state, and the first clamping plate 11 and the second clamping plate 12 will move backward to move the sling between the first clamping plate 11 and the second clamping plate 12, and then the second clamping plate 12 will move downward under the cooperation of the guide slot 14 and the guide rod 15, and the second clamping plate 12 will cooperate with the first clamping plate 11 to clamp the sling; then start the second driving assembly, so that the second driving assembly drives the first clamping plate 11 and the second clamping plate 12 to move toward each other first and then away from each other, and the movement toward each other is to move the second clamping plate 12 to the side away from the sleeve rod 3 to pull the second clamping plate 12 and the sleeve rod 3 The purpose of moving backwards is to make the two second clamping plates 12 pull the lifting sling between them outwards, and after the detection is completed, the second clamping plate 12 and the first clamping plate 11 are moved back to the initial position, and then the first driving assembly drives the C-shaped mounting plate 6 to move forward back to the initial position, and the first roller 7 and the second roller 8 are replaced to clamp the lifting sling, and then the third driving assembly is started, and the third driving assembly drives the two first rollers 7 to rotate synchronously. After the first roller 7 and the second roller 8 clamp the lifting sling, the friction between the first roller 7 and the lifting sling is large. When the lifting sling cannot move, the friction between the first roller 7 and the lifting sling will drive the first roller 7 to move along the lifting sling, and the first roller 7 will drive the entire test assembly to move, and after the first roller 7 moves a detection length, the first driving assembly drives the first clamping plate 11 and the second clamping plate 12 to clamp the lifting sling, and then the second driving assembly drives the two second clamping plates 12 to move and detect the lifting sling; it should be noted that, Figure 1 As shown, the distance between the left sleeve rod 3 and the test assembly is smaller than the distance between the right sleeve rod 3 and the test assembly. When the length of the sling is greater than the distance between the two sleeve rods 3, the portion of the sling between the right sleeve rod 3 and the test assembly is in a relaxed state. When the friction between the first slide plate 4 and the bottom plate 1 is sufficient, the rotation of the first roller 7 and the second roller 8 will drive the portion of the sling between the right sleeve rod 3 and the test assembly to move leftward until the portion of the sling between the right sleeve rod 3 and the test assembly is in a taut state. Thereafter, when the first roller 7 and the second roller 8 rotate again, the first roller 7 will drive the first slide plate 4 to overcome the friction of the bottom plate 1 and move rightward. Through the setting of the test assembly, the present invention can test the sling section by section, which can make the detection result of the sling more accurate, and through the setting of the first roller 7 and the second roller 8, the present invention can be applied to the testing of slings of different lengths.

[0029] When the above scheme is put into practical use, Figure 2 As shown, when the third driving assembly is working, the motor 31 drives the pulley 17 on the left to rotate, and the pulley 17 on the left drives the pulley 17 and the tensioning pulley 19 on the right to rotate through the transmission belt 21. The two pulleys 17 will respectively drive the two first rollers 7 to rotate synchronously in the same direction, so that the first roller 7 can drive the first slide plate 4 to move or drive the lifting sling to move. At the same time, through the arrangement of the second slider 18 and the tensioning spring 20, the pulley 17 can work more stably.

[0030] As a further solution of the present invention, the second driving assembly includes two connecting rods 22, and the two connecting rods 22 are rotatably connected to the two second clamping plates 12 respectively.

The top end of the second cylinder 24 is fixedly connected to the second slide plate 5 through a second mounting plate 25.

[0031] When the above scheme is put into practical use, Figure 2 As shown, when the second driving assembly is working, the second cylinder 24 drives the driving block 23 to move in the vertical direction, and the driving block 23 can drive the two second clamping plates 12 to move toward or away from each other through the two connecting rods 22, so that the second clamping plates 12 can cooperate with the first clamping plates 11 to pull the test sling, and in this solution, the distance between the two second clamping plates 12 can be adjusted by starting the driving block 23 in the vertical direction through the cylinder, and the length of each sling detection can be adjusted according to actual needs, which can greatly improve the detection efficiency of the sling.

[0032] As a further solution of the present invention, the first driving assembly includes a first cylinder 26 , an output end of the first cylinder 26 is fixedly connected to the second slide 5 , and a fixed end of the first cylinder 26 is fixedly connected to the first slide 4 .

[0033] When the above solution is put into practical use, the first slide plate 4 can be driven to slide on the second slide plate 5 by the extension and contraction of the first cylinder 26 .

[0034] As a further solution of the present invention, a sponge 27 is fixedly connected to the outer circumferential wall of the first roller 7 and the second roller 8 .

[0035] When the above scheme is put into practical use, the sponge body 27 can be provided to make the sling better fit with the first roller 7 and the second roller 8, and the first roller 7 and the second roller 8 can better move relative to the sling.

[0036] As a further solution of the present invention, a third slider 28 is slidably connected to the first mounting plate 2, a clamping block 29 is slidably connected to the third slider 28, and a second spring 30 for resetting the clamping block 29 is fixedly connected to the clamping block 29.

[0037] When the above scheme is put into actual use, after the two ends of the sling are inserted into the sleeve rod 3, the staff can push the third slider 28 toward one end close to the sling, so that the clamping block 29 presses the sling under the action of the second spring 30, which can make the sling more stable during testing.

[0038] Working principle: The staff inserts the two ends of the sling into the sleeve rod 3 respectively, and places the sling between the first roller 7 and the second roller 8. When testing, under the action of the first spring 10, the second roller 8 presses the sling against the first roller 7, and then starts the first drive assembly, so that the first drive assembly drives the second slide 5 on the first slide 4 to move to the position as shown in the figure. Figure 1 As shown in the figure, the second slide plate 5 will drive the first roller 7, the second roller 8, the first clamping plate 11 and the second clamping plate 12 to move synchronously through the C-shaped mounting plate 6; the second clamping plate 12 will drive the guide rod 15 to slide in the guide slot 14; Figure 3As shown, the guide rod 15 will first move obliquely upward in the guide slot 14, then move horizontally, then move obliquely downward, and then move horizontally, and the height of the oblique downward movement is greater than the height of the oblique upward movement, and the guide rod 15 will drive the second clamping plate 12 and the second roller 8 to move upward first while moving backward, so that the first roller 7 and the second roller 8 cancel the clamping of the sling, and then the first clamping plate 11 and the second clamping plate 12 will be in an open state, and the first clamping plate 11 and the second clamping plate 12 will move backward to move the sling between the first clamping plate 11 and the second clamping plate 12, and then the second clamping plate 12 will move downward under the cooperation of the guide slot 14 and the guide rod 15, and the second clamping plate 12 will cooperate with the first clamping plate 11 to clamp the sling; then start the second driving assembly, so that the second driving assembly drives the first clamping plate 11 and the second clamping plate 12 to move toward each other first and then away from each other, and the movement toward each other is to move the second clamping plate 12 to the side away from the sleeve rod 3 to pull the second clamping plate 12 and the sleeve rod 3 The purpose of moving backwards is to make the two second clamping plates 12 pull the lifting sling between them outwards, and after the detection is completed, the second clamping plate 12 and the first clamping plate 11 are moved back to the initial position, and then the first driving assembly drives the C-shaped mounting plate 6 to move forward back to the initial position, and the first roller 7 and the second roller 8 are replaced to clamp the lifting sling, and then the third driving assembly is started, and the third driving assembly drives the two first rollers 7 to rotate synchronously. After the first roller 7 and the second roller 8 clamp the lifting sling, the friction between the first roller 7 and the lifting sling is large. When the lifting sling cannot move, the friction between the first roller 7 and the lifting sling will drive the first roller 7 to move along the lifting sling, and the first roller 7 will drive the entire test assembly to move, and after the first roller 7 moves a detection length, the first driving assembly drives the first clamping plate 11 and the second clamping plate 12 to clamp the lifting sling, and then the second driving assembly drives the two second clamping plates 12 to move and detect the lifting sling; it should be noted that, Figure 1 As shown, the distance between the left sleeve rod 3 and the test assembly is smaller than the distance between the right sleeve rod 3 and the test assembly. When the length of the sling is greater than the distance between the two sleeve rods 3, the portion of the sling between the right sleeve rod 3 and the test assembly is in a relaxed state. When the friction between the first slide plate 4 and the bottom plate 1 is sufficient, the rotation of the first roller 7 and the second roller 8 will drive the portion of the sling between the right sleeve rod 3 and the test assembly to move leftward until the portion of the sling between the right sleeve rod 3 and the test assembly is in a taut state. Thereafter, when the first roller 7 and the second roller 8 rotate again, the first roller 7 will drive the first slide plate 4 to overcome the friction of the bottom plate 1 and move rightward. Through the setting of the test assembly, the present invention can test the sling section by section, which can make the detection result of the sling more accurate, and through the setting of the first roller 7 and the second roller 8, the present invention can be applied to the testing of slings of different lengths.
