[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] Please see Figures 1 to 4 This embodiment proposes a wire rope testing device for bridge and gantry cranes, including a mounting plate 1, an auxiliary roller 2, a test column 3, a ball bearing 4, an auxiliary spring 5, a moving plate 6, a connecting frame 7, a placement box 8, an absorption layer 9, a discharge plate 10, a discharge hole, and a mounting rod 11.

[0026] like Figure 3 and Figure 4As shown, the auxiliary roller 2 is installed on the side of the mounting plate 1. The test column 3 passes through the inside of the mounting plate 1. The test column 3 is rotatably connected to a ball bearing 4. The auxiliary spring 5 is installed on the outer side of the mounting plate 1. The outer surface of the test column 3 passes through the auxiliary spring 5. A movable plate 6 is installed on the outer end of the test column 3 and the auxiliary spring 5. A connecting frame 7 is installed on the side of the movable plate 6. The connecting frame 7 passes through the inside of the mounting plate 1. A placement box 8 is installed on the lower surface of the connecting frame 7. An absorbent layer 9, which is a sponge block, is slidably connected inside the placement box 8. During use, the absorbent layer 9... The device needs to absorb the water-based paint first. After the device is tested, the absorption layer 9, mounting rod 11, discharge plate 10 and placement box 8 need to be cleaned immediately to prevent the water-based paint from drying out. The discharge plate 10 is slidably connected to the inside of the placement box 8. The discharge plate 10 has a discharge hole inside. When the discharge plate 10 squeezes the absorption layer 9, the squeezed water-based paint is discharged along the discharge hole and adheres to the area below the broken wire rope. The mounting rod 11 is installed on the side of the discharge plate 10. The outer surface of the mounting rod 11 penetrates the placement box 8 and the absorption layer 9 respectively.

[0027] like Figure 4 As shown, a first connecting piece 12 is installed on the side of the placement box 8, a connecting spring 13 is installed on the side of the first connecting piece 12, a second connecting piece 14 is installed on the outer end of the connecting spring 13, the outer surface of the mounting rod 11 passes through the first connecting piece 12 and the connecting spring 13 respectively, the outer end of the mounting rod 11 passes through the second connecting piece 14, a fixing pin 15 is threaded through the side of the second connecting piece 14, and one end of the fixing pin 15 threaded through the second connecting piece 14 is threaded through the mounting rod 11.

[0028] like Figure 3 As shown, an adjustment post 16 is installed on the outer side of the mounting plate 1. An adjustment frame 17 is slidably connected to the outer side of the adjustment post 16. An adjustment pin 18 is threaded through the upper surface of the adjustment frame 17. One end of the adjustment pin 18, which is threaded through the adjustment frame 17, abuts against the adjustment post 16.

[0029] In this embodiment, as Figure 1 and Figure 2 As shown, a lifting column 19 is installed on the lower surface of the adjusting frame 17. A lifting frame 20 is slidably connected to the outer side of the lifting column 19. A push rod motor 21 is installed inside the lifting frame 20. The push rod motor 21 requires an external single-control switch to control its start and stop. The push rod motor 21 requires an external power supply. The outer surface of the push rod motor 21 passes through the lifting column 19. The output end of the push rod motor 21 is installed on the inner wall of the top of the lifting column 19. A support plate 22 is installed on the lower surface of the lifting frame 20. A universal self-locking wheel 25 is installed on the lower surface of the support plate 22. A fixing frame 23 is installed on the inner side of the support plate 22. A reinforcing plate 24 is installed on the upper surface of the support plate 22. The inner side of the reinforcing plate 24 is installed on the outer side of the lifting frame 20.

[0030] Working principle: The device is moved to the detection point by the universal self-locking wheel 25. The absorbent layer 9 that absorbs water-based paint is placed into the placement box 8. The discharge plate 10 is manipulated to make the mounting rod 11 pass through the absorbent layer 9 and into the placement box 8. The mounting rod 11 passes through the first connecting piece 12 and is inserted into the second connecting piece 14. The discharge plate 10 slides into the placement box 8. The fixing pin 15 is manipulated to pass through the second connecting piece 14 and be inserted into the mounting rod 11. Then, the fixing pin 15 is rotated clockwise to fix the mounting rod 11 in the second connecting piece 14.

[0031] Loosen the adjusting pin 18 counterclockwise, and move the adjusting column 16 inward along the adjusting frame 17. The inward movement of the adjusting column 16 causes the mounting plate 1 to move inward, which in turn causes the auxiliary roller 2 to move inward and contact the wire rope. The inward movement of the mounting plate 1 causes the test column 3 to move inward, which in turn causes the ball 4 to move inward and contact the wire rope. This causes the test column 3 to move outward along the mounting plate 1, which in turn causes the moving plate 6 to move outward. The outward movement of the moving plate 6 stretches the auxiliary spring 5. After adjustment, rotate the adjusting pin 18 clockwise to tighten the adjusting column 16.

[0032] Start the push rod motor 21. The output end of the push rod motor 21 moves upward, causing the lifting column 19 to move upward. The lifting column 19 moves upward along the lifting frame 20. The upward movement of the lifting column 19 causes the adjusting frame 17 to move upward. The upward movement of the adjusting frame 17 causes the adjusting column 16 to move upward. The upward movement of the adjusting column 16 causes the mounting plate 1 to move upward, so that the auxiliary roller 2 and the ball 4 roll upward along the wire rope.

[0033] When the ball bearing 4 encounters the damaged area, it moves inward and sinks into the damaged area. The auxiliary spring 5 rebounds, causing the moving plate 6 to move inward. The moving plate 6 moves inward, causing the test column 3 to move inward. The moving plate 6 moves inward, causing the connecting frame 7 to move inward. The connecting frame 7 moves inward, causing the placement box 8 to move inward. The placement box 8 moves inward, causing the discharge plate 10 to move inward and come into contact with the wire rope. This causes the discharge plate 10 to squeeze the absorption layer 9 and squeeze the water-based coating out along the discharge hole, marking the area below the damaged location.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
