Description

Technical Field

[0001] The present invention relates to the technical field of wire rope detection, and in particular to a multi-source collaborative detection system and method for multi-rope friction hoisting wire ropes. Background Art

[0002] Wire rope is widely used as an important component of transportation, lifting and carrying equipment. Due to its advantages such as strong overload capacity and light weight, it plays a role in personnel lifting, material transportation and equipment transmission. It is widely used in many important fields of the national economy such as coal, metallurgy, water conservancy, transportation, etc. However, as a key component in engineering, the working environment of wire rope is usually very harsh. In actual use, various friction, extrusion and impact phenomena will cause damage to the wire rope to a certain extent, which will cause equipment failure and even threaten the life safety of the user. Therefore, in order to ensure the safety of production, it is necessary to study and optimize the non-destructive testing technology of wire rope.

[0003] Damage detection of wire ropes can be roughly divided into three categories: cross-sectional loss detection, local damage detection, and structural defect detection. Common methods for nondestructive testing of wire ropes include electromagnetic detection, visual detection, acoustic emission detection, ultrasonic detection, eddy current detection, infrared detection, and X-ray detection. However, the existing nondestructive testing technologies each have their own limitations and cannot fully meet the high requirements of modern production. The friction lifting system includes two layouts: floor-standing and well tower. The movement directions of the wire ropes are different. The angle between the floor-standing wire rope and the horizontal plane is less than 90°, while the well tower wire rope is perpendicular to the horizontal plane. The existing device can only detect a single type of friction hoist and cannot be used for the detection of two systems at the same time, which has the problem of a narrow application range. Summary of the invention

[0010] By adopting the above-mentioned technical solution, the two groups of translation components can drive the two parts of the visual-electromagnetic collaborative detection device to move, and the sliding direction of the translation component is consistent with the long side direction of the detection hole. This setting ensures that the translation component will not interfere with the wire rope to be detected during the process of driving the visual-electromagnetic collaborative detection device to move.

[0013] By adopting the above technical solution, when testing the steel wire rope, two sets of second linear transmission drive members drive the two bearing plates to abut against each other, and the two semicircular grooves are spliced ​​into a circular hole. At this time, the steel wire rope to be tested and the circular hole spliced ​​by the two semicircular grooves are coaxial.

At this time, the excitation device 7 can simultaneously excite multiple steel wire ropes to be detected. The first semicircular positioning groove 10 and the second semicircular positioning groove 11 have a limiting effect on the steel wire rope, which can reduce the possibility of interference between adjacent steel wire ropes during the excitation process.

[0063] In the present embodiment, the first linear transmission drive member 511, the second linear transmission drive member 611 and the third linear transmission drive member 73 have the same structure. In the present embodiment, the specific structure can adopt the motor-screw linear transmission mechanism commonly used in the field to realize linear transmission, which can be controlled by an electrical control system. Specifically, the electrical control system can control the action of the motors of the first linear transmission drive member 511, the second linear transmission drive member 611 and the third linear transmission drive member 73 through PLC, thereby controlling the action of the detection system. Since this control method is well known to those skilled in the art, it will not be described in detail here.

[0064] It should be added that the structures of the first linear transmission driver 511, the second linear transmission driver 611 and the third linear transmission driver 73 are not limited to the above description, and their structures can also be transmission structures such as linear motors or cylinders that can achieve linear movement.

[0065] The implementation principle of a multi-rope friction lifting wire rope multi-source collaborative detection system of the embodiment of the present invention is as follows: when detecting the wire rope, multiple wire ropes to be detected are inserted into the detection hole 4, and then the angle of the working platform 3 is adjusted by the angle adjustment mechanism 2, so that the working platform 3 and the wire rope to be detected remain vertical, and then the visual-electromagnetic collaborative detection device 6 is driven to move to the test position by the translation mechanism 5, so that the wire rope to be detected is located in the middle area of ​​the visual-electromagnetic collaborative detection device 6, and the multiple wire ropes to be detected are excited by the excitation device 7, and then the visual data and electromagnetic data of the wire rope are collected by the camera 616 and the Hall element array 614, and the data of the wire rope to be detected is collected one by one in the same way. The staff analyzes the collected data, and after processing, the surface damage and internal damage of the wire rope are obtained, and the quality of the wire rope can be judged. The present invention can detect multiple multi-rope friction lifting wire ropes at different angles to the horizontal plane, has a wide range of applications, and can ensure the accuracy of the test results.

[0066] Reference Figures 1 to 7 The present invention also provides a multi-source collaborative detection method for multi-rope friction lifting wire ropes, comprising the following steps:

[0067] S1. After the multiple steel wire ropes to be tested are in place, the lifting drive 22 drives the working platform 3 to change its angle until the working platform 3 and the steel wire ropes to be tested are kept vertical. In this process, the position of the steel wire ropes can be manually detected.

[0068] S2. The two groups of first linear transmission driving members 511 drive the visual-electromagnetic cooperative detection device 6 to move to the test position.

[0069] S3. The two supporting plates 613 are driven to move closer by two sets of second linear transmission drive members 611. After the two supporting plates 613 are in contact, the Hall element array 614, the light source 615 and the camera 616 surround the steel wire rope to be tested, so as to more accurately collect the visual data and electromagnetic data of the steel wire rope.

[0070] S4. The driving motor 6251 drives the transmission screw 6252 to rotate, and drives the encoder support frame 622 to move, so that the speed measuring wheel 624 contacts the steel wire rope to be measured.

[0071] S5. The plurality of third linear transmission driving members 73 drive the first excitation part 71 to move close to the second excitation part 72. The excitation device 7 in the closed state excites the steel wire rope to be tested, and simultaneously starts the camera 616 and the light source 615. The Hall element array 614 and the camera 616 collect electromagnetic and visual data respectively. During the detection process, the steel wire rope to be tested moves, driving the speed measuring wheel 624 to rotate synchronously. The encoder 623 converts the angular displacement of the speed measuring wheel 624 into an electrical signal, and then into a counting pulse.

[0072] S6. The staff analyzes the collected electromagnetic and visual data to determine whether the wire rope can be used normally, and determines the damaged location of the wire rope based on the counting pulses.

[0073] S7. After the inspection of one steel wire rope is completed, S2 to S6 are repeated until the inspection of multiple steel wire ropes is completed.

[0074] By adopting the above technical scheme, the present invention can detect multiple multi-rope friction lifting wire ropes at different angles to the horizontal plane, has a wide range of applications, and can quickly and reliably grasp the surface and internal damage of the wire ropes.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
