[0086] With reference to Figure 2 , the second rotating shafts 24 are horizontally arranged, correspond in number to the first rotating shafts 22 and are located directly above the first rotating shafts 22, the second rotating shafts 24 are rotationally arranged in the detection box 1, six adjusting grooves 13 are symmetrically formed in the detection box 1, the two ends of the second rotating shafts 24 are slidingly arranged in the adjusting grooves 13, the driven rollers 25 correspond in number to the second rotating shafts 24, the driven rollers 25 are the same in shape and size as the driving rollers 23, the driven rollers 25 are fixedly sleeved on the second rotating shafts 24, the chain wheels 26 correspond in number to the first rotating shafts 22, the chain wheels 26 are coaxially fixedly sleeved on the first rotating shafts 22, and the chains 27 are sequentially wound on all the chain wheels 26 to form a closed loop.

[0087] When the steel wire rope is subjected to nondestructive testing, the motor 21 is started, the motor 21 starts to rotate and drives the first rotating shafts 22 connected therewith to rotate, the chain wheels 26 are sleeved on the first rotating shafts 22, and the chain wheels 26 on the three first rotating shafts 22 are connected in a closed loop through the chains 27, so that when the first rotating shafts 22 rotate, the other two first rotating shafts 22 are driven by the chains 27 to rotate synchronously, and the three driving rollers 23 are driven to rotate synchronously, the driving roller 23 is composed of a middle cylinder and two side circular tables, and the shape is conducive to better clamping and guiding the steel wire rope.

[0088] The steel wire rope to be tested enters from the rope inlet 11 and is placed between the driving rollers 23 and the driven rollers 25, when the driving rollers 23 rotate, the second rotating shafts 24 and the driven rollers 25 also rotate under the action of friction, the second rotating shafts 24 and the driven rollers 25 assist in supporting and guiding the steel wire rope to move smoothly, the driving rollers 23 and the driven rollers 25 drive the steel wire rope to move towards the rope outlet 12 through the friction between the driving rollers 23, the driven rollers 25 and the steel wire rope, so as to realize the conveying of the steel wire rope in the detection box 1, ensure that the steel wire rope can continuously and stably pass through the detection box 1, and provide stable conveying conditions for the subsequent nondestructive testing assembly 3 to test the steel wire rope.

The two ends of the third communication pipe 37 are in communication with the oil tank 36 and the first communication pipe 34, respectively. The two ends of the fourth communication pipe 38 are in communication with the oil tank 36 and the second communication pipe 35, respectively. Two valves 39 are fixedly installed on the third communication pipe 37 and the fourth communication pipe 38, respectively.

[0097] In the detection using the steel wire rope nondestructive testing device, the steel wire rope to be detected enters the detection box 1 through the rope inlet 11, the conveying assembly 2 drives the steel wire rope to move stably by friction, when the steel wire rope passes through the detection area, the detection assembly 3 works, the detection rod 33 is always in abutment with the steel wire rope, when the steel wire rope has defects, such as local protrusions, depressions or changes in thickness, the steel wire rope will exert an external force on the detection rod 33, after the detection rod 33 is forced, the movable end of the detection telescopic rod 31 is displaced, the depression will make the detection telescopic rod 31 elongate, the oil in the rod cavity enters the injection assembly 4 through the first communication pipe 34, and the protrusion will make the detection telescopic rod 31 contract, the oil in the rod cavity enters the injection assembly 4 through the second communication pipe 35, which triggers the injection marking, and the pigment is sprayed on the corresponding defect position of the steel wire rope, so that the detection and marking of the defects of the steel wire rope are realized, and an intuitive basis is provided for subsequent maintenance or replacement.

[0098] With reference to Figure 4 and Figure 5 , the injection assembly 4 includes a pigment tank 41, a pigment pipe 42, a high-pressure nozzle 43, a control telescopic rod 44 and a second spring 45. The pigment tank 41 is arranged at the top of the detection box 1, the pigment pipe 42 is arranged vertically, one end of the pigment pipe 42 is in communication with the pigment tank 41, the high-pressure nozzle 43 is fixedly installed at the end of the pigment pipe 42 away from the pigment tank 41, the specific injection mode and injection principle of the high-pressure nozzle 43 are the existing technology in the field, therefore, in the embodiment of the application, they are not described in detail, the fixed end of the control telescopic rod 44 is fixedly installed on the outer wall of the pigment pipe 42, the first communication pipe 34 and the second communication pipe 35 are both in communication with the rod cavity of the control telescopic rod 44 through pipes, the movable end of the control telescopic rod 44 is arranged in the pigment pipe 42, when the control telescopic rod 44 is in the elongated state, the movable end of the control telescopic rod 44 abuts against the inner wall of the pigment pipe 42, and the second spring 45 is arranged in the rod cavity of the control telescopic rod 44.

[0099] Before the steel wire rope starts to be detected, the control telescopic rod 44 is in the elongated state, the movable end of the control telescopic rod 44 abuts against the inner wall of the pigment pipe 42 tightly, at this time, the second spring 45 is in a natural state or a pre-compressed state. The pigment tank 41 stores the pigment used for marking, due to the blockage of the movable end of the control telescopic rod 44, the pigment cannot flow from the pigment pipe 42 to the high-pressure nozzle 43, and the injection assembly 4 is in a triggered state.

[0100] When the detection assembly 3 detects the steel wire rope, if the detection telescopic rod 31 detects that the steel wire rope changes in thickness due to defects, the detection telescopic rod 31 is driven to act, and the change in the hydraulic pressure in the rod cavity and the rodless cavity of the detection telescopic rod 31 causes the hydraulic pressure in the rod cavity of the control telescopic rod 44 to change, and the change in the hydraulic pressure in the rod cavity of the control telescopic rod 44 causes the movable end of the control telescopic rod 44 to start to contract against the elastic force of the second spring 45. As the movable end of the control telescopic rod 44 contracts, a channel is formed between the movable end and the inner wall of the material spraying pipe 42, and the paint in the paint box 41 flows to the high-pressure spray head 43 through the material spraying pipe 42 under the action of gravity, and the paint is sprayed to the defect position of the steel wire rope, and the marking of the defect is completed.

[0101] When the defect position of the steel wire rope passes through the detection area, the detection telescopic rod 31 returns to the initial state, and the hydraulic pressure in the rod cavity and the rodless cavity also returns to normal. The change in the hydraulic pressure in the rod cavity of the control telescopic rod 44 causes the second spring 45 to push the movable end of the control telescopic rod 44 to elongate again until the movable end abuts against the inner wall of the material spraying pipe 42 to block the flow channel of the paint, and the spraying assembly 4 returns to the initial trigger state and waits for the next detection of defects to work again.

[0102] Referring to Figure 4 The pressure assembly 6 includes a color sensor 61, an electric push rod 62, a pressing block 63, and a paint disc 64. The color sensor 61 is fixedly installed on the top wall of the detection box 1 and located behind the second driven roller 25 along the movement direction of the steel wire rope. The electric push rod 62 is vertically arranged, and the fixed end of the electric push rod 62 is fixedly installed on the top wall of the detection box 1. The color sensor 61 and the electric push rod 62 are sequentially and spaced apart along the movement direction of the steel wire rope. The pressing block 63 is fixedly installed on the movable end of the electric push rod 62. The paint disc 64 is fixedly installed in the detection box 1 and located between the two driven rollers 23 with the upper surface slightly lower than the driven rollers 23. The paint disc 64 is arranged directly below the pressing block 63.

[0103] When the steel wire rope is driven by the conveying assembly 2 to pass through the rope inlet 11, the detection assembly 3, and the spraying assembly 4 in sequence, the defect position marked on the steel wire rope moves to the detection area of the pressure assembly 6. When the color sensor 61 captures the color of the paint sprayed on the defect position of the steel wire rope by the spraying assembly 4, a signal is immediately sent to the electric push rod 62. The electric push rod 62 receives the signal and starts to move downward, driving the pressing block 63 to synchronously descend and apply pressure to the steel wire rope below. The pressing block 63 simulates the dynamic load condition of the steel wire rope in actual use to detect the tensile strength of the steel wire rope under the pressure.

[0104] If the steel wire rope is stretched and deformed under the pressure of the pressure block 63, the steel wire rope will move downward and contact the upper surface of the pigment disc 64. Since the upper surface of the pigment disc 64 is slightly lower than the driving roller 23, and the surface has pigment, after the steel wire rope contacts the pigment disc 64, the pigment will adhere to the steel wire rope, marking the defect part again, prompting that the section of the steel wire rope is insufficient in tensile strength under the current pressure. If the steel wire rope does not obviously stretch and deform under the pressure of the pressure block 63, it indicates that the tensile strength of the section of the steel wire rope meets the requirements, the steel wire rope will not contact the pigment disc 64, and no additional pigment mark will be left. After completing the first pressure detection, the electric push rod 62 drives the pressure block 63 to rise and reset to the initial position, waiting for the next marked defect part of the steel wire rope to enter the detection area of the pressure assembly 6, and repeating the above detection process to continuously detect the tensile strength of the steel wire rope at the marked defect part, ensuring the comprehensiveness and accuracy of the quality control of the steel wire rope.

[0105] The implementation principle of the steel wire rope nondestructive testing device is as follows: during detection, the steel wire rope enters from the wire inlet 11, the cleaning assembly 7 operates first, and the first rotating shaft 22 in the conveying assembly 2 drives the cleaning ring 71 to rotate through a series of gear transmissions, so that the brush 72 cleans the surface of the steel wire rope. At the same time, the conveying assembly 2 is driven by the motor 21, the motor 21 drives the first rotating shaft 22, and the three first rotating shafts 22 are synchronously rotated through the chain wheel 26 and the chain 27, so that the driving roller 23 rotates, and the driven roller 25 adjusts the distance from the driving roller 23 under the action of the adjusting part 5, and the two cooperate to move the steel wire rope stably by using friction.

[0106] The plurality of detection assemblies 3 are arranged in sequence along the movement direction of the steel wire rope. In each detection assembly 3, the two symmetrical detection telescopic rods 31 can sensitively respond to the change in the thickness of the steel wire rope, cooperate with the first spring 32, convert the detected defect information into a hydraulic signal, and transmit the signal to the spraying assembly 4 through the communication pipe. After receiving the signal, the spraying assembly 4 controls the telescopic rod 44 to act, so that the pigment is sprayed from the pigment tank 41 to the defect part of the steel wire rope through the spraying pipe 42 and the high-pressure nozzle 43, and visual marking is realized.

[0107] During detection, the pressure assembly 6 operates synchronously, and the color sensor 61 detects the marking pigment, triggers the electric push rod 62 to drive the pressure block 63 to press down, applies a dynamic load to the steel wire rope, and judges the tensile strength of the steel wire rope by observing whether the steel wire rope contacts the pigment disc 64.

[0108] The whole device realizes the full-process damage detection of the steel wire rope from cleaning, conveying, detection to marking and tensile strength evaluation through the close cooperation of each assembly, effectively improves the efficiency and reliability of the nondestructive testing of the steel wire rope, reduces the detection cost, and has a wide range of applications and is convenient to maintain and overhaul.

[0109] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
