[0024] A control panel 25 is installed on the top side of the detector body 1, and the control panel 25 is electrically connected to the electrode sheet 6, the electric sheet 7 and the indicator light 11, wherein the control panel 25 is used for signal transmission between the electrode sheet 6 and the electric sheet 7, and signal transmission to the indicator light 11; during operation, in actual applications, when the wire rope is detected, it is not possible to provide timely feedback to remind the staff of wire breakage, which will affect the detection efficiency of the wire rope and cause quality problems in the produced wire rope. When the wire rope needs to be detected, the wire rope is passed between the auxiliary roller 10 and the conveying roller 14 in the installation frame 2, and is brought into contact with the auxiliary roller 10. In this process, the movable rod 5 will be squeezed by the wire rope and shrink into the sleeve 3, while compressing the elastic rod 5. The spring 4 will also be compressed. When the movable rod 5 moves inward, the electric sheet 7 will contact the electrode sheet 6 to form a complete circuit. At this time, the indicator light 11 will receive the electrical signal and emit light, prompting the staff that the wire rope has been detected. The signals of the electrode sheet 6 and the electric sheet 7 can be transmitted and processed through the control panel 25, and the detection results can be displayed on the indicator light 11. If the wire rope is broken during the detection process, the electrode sheet 6 and the electric sheet 7 are separated, and the indicator light 11 goes out.

The wire rope is composed of steel wire, rope core and grease. During its production process, by detecting the broken wire situation, possible defects of the steel wire in the twisting process can be discovered in time, thereby ensuring the quality of the wire rope. When testing it, the wire rope needs to be conveyed. By starting the driving motor 12, the driving motor 12 can drive the rotating shaft 13 and the conveying roller 14 to rotate, so that the wire rope moves through the detector body 1 under the drive of the conveying roller 14, so that the wire rope can be automatically conveyed, the detection efficiency can be improved, and the labor intensity of manual operation can be reduced.

[0026] Furthermore, the rotating shaft 13 is provided with a first active bevel gear 15 on the outside of the mounting frame 2, a fixing block 16 is fixedly provided on the outer wall of one side of the detector body 1, a connecting shaft 17 is movably provided on one end of the fixing block 16, a first driven bevel gear 18 is provided on one end of the connecting shaft 17, and the first active bevel gear 15 and the first driven bevel gear 18 are meshed with each other;

The rotation of the feed roller 23 can send the wire rope out from the outlet of the conveying chamber 24, so as to realize automatic conveying and detection of the wire rope, and can effectively protect and support the wire rope to avoid interference and damage by external factors during the conveying process.

[0028] Working principle: In practical applications, when testing the wire rope, it is not possible to provide timely feedback to remind the staff of wire breakage, which will affect the detection efficiency of the wire rope and cause quality problems in the produced wire rope. When the wire rope needs to be tested, the wire rope is passed between the auxiliary roller 10 and the conveying roller 14 in the installation frame 2, and is brought into contact with the auxiliary roller 10. During this process, the movable rod 5 is squeezed by the wire rope and contracts into the sleeve 3, and the compression spring 4 is also compressed.

The control panel 25 can transmit and process the signals of the electrode sheet 6 and the electric sheet 7, and the detection result will be displayed on the indicator light 11.

The staff can judge whether the wire rope has a broken wire problem according to the on and off situation of the indicator light 11, and can give timely feedback to the staff, so that the staff can handle it in time, speed up the production efficiency of the wire rope, and avoid quality problems in the production of the wire rope.

[0029] At the same time, by starting the driving motor 12, the driving motor 12 can drive the rotating shaft 13 and the conveying roller 14 to rotate, so that the steel wire rope moves through the detector body 1 under the drive of the conveying roller 14, which can realize the automatic conveying of the steel wire rope, improve the detection efficiency, and reduce the labor intensity of manual operation;

[0030] The conveying roller 14 can deliver the steel wire rope from the entrance of the conveying chamber 24 and convey it in the conveying chamber 24. When the rotating shaft 13 rotates, it drives the rotation of the No. 1 active bevel gear 15. Through the meshing transmission of the No. 1 active bevel gear 15 and the No. 1 driven bevel gear 18, the No. 1 driven bevel gear 18 is driven, so that the connecting shaft 17 drives the movement of the No. 2 active bevel gear 19. Through the meshing transmission of the No. 2 active bevel gear 19 and the No. 2 driven bevel gear 22, the No. 2 driven bevel gear 22 is driven to rotate, so that the connecting shaft 21 drives the feeding roller 23 to rotate. The rotation of the feeding roller 23 can deliver the steel wire rope from the outlet of the conveying chamber 24, so as to realize automatic conveying and detection of the steel wire rope, and effectively protect and support the steel wire rope to prevent it from being disturbed and damaged by external factors during the conveying process.
