Description

Technical Field

[0001] This utility model relates to the field of wire rope testing technology, and in particular to a non-contact testing device for mining wire ropes. Background Technology

[0002] Mining wire ropes are widely used in various fields such as mining, transportation, and hoisting, and are a crucial component of mining equipment. Wire ropes are woven from steel wires in a specific arrangement, possessing excellent properties such as high strength, wear resistance, and tensile strength, enabling them to operate stably for extended periods under complex and harsh environmental conditions. Mining wire ropes are primarily used in mine hoisting systems, responsible for transporting ore, personnel, and other equipment, bearing enormous loads and repeated impacts. During the mining process, wire ropes not only face the challenges of moisture and corrosion in the underground environment but also must withstand frequent bending and stretching, requiring excellent fatigue resistance and a long service life.

[0003] To ensure the safe operation of mining wire ropes under high loads and complex environments, quality control of wire ropes is crucial. However, despite continuous improvements in modern wire rope manufacturing technology, defects such as cracks and inclusions can still easily appear on the surface of wire ropes during long-term use, leading to sudden breakage and serious safety accidents. In addition, inclusions may affect the uniformity and stability of the wires, thereby reducing the overall strength and tensile strength.

[0004] Therefore, there is an urgent need to provide a non-contact detection device for steel wire ropes in mines to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a non-contact detection device for steel wire ropes in mining.

[0006] To solve the above-mentioned technical problems, the present invention provides a non-contact detection device for steel wire ropes in mines, including a main body and symmetrical adjustment frames disposed thereon. The main body is provided with a support frame adjacent to the adjustment frame, and both the support frame and the adjustment frame are provided with support rollers.

[0007] The main body is provided with a segmented rotation detection mechanism located between the support rollers. The segmented rotation detection mechanism includes a drive component and a moving component disposed on the main body adjacent to the support frame, which are used for segmented detection of mining wire rope. A detection component is disposed between the drive component and the moving component for flipping detection, so as to realize all-round detection.

[0008] The present invention is further configured such that: the detection component includes a first hexagonal plate and a second hexagonal plate, and the thickness of the second hexagonal plate is greater than that of the first hexagonal plate; a plurality of rotatably connected links are provided between the first hexagonal plate and the second hexagonal plate; and a detection probe device is provided between the links.

[0009] The present invention is further configured such that: a rope hole is provided on the second hexagonal plate, a first hydraulic cylinder is provided on the second hexagonal plate with the rope hole as the center of symmetry, and a clamp is provided on the piston end of the first hydraulic cylinder.

[0010] The present invention is further configured such that: the driving assembly includes a motor fixed to the bottom surface of the main body and a drive shaft disposed thereon; the main body is provided with a first support plate adjacent to the support frame; and a first synchronous pulley and a second synchronous pulley are disposed on the first support plate and the drive shaft; and a synchronous belt penetrating the main body is disposed between the first synchronous pulley and the second synchronous pulley.

[0011] The present invention is further configured such that: the first hexagonal plate is fixed to the second synchronous wheel and passes through the first support plate.

[0012] The present invention is further configured such that: the moving component includes a slide groove formed on the main body, a second hydraulic cylinder is provided on the bottom surface of the main body, and a second support plate is fixed at the piston rod end of the second hydraulic cylinder, which passes through the slide groove and is rotatably connected to the second hexagonal plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through the design of a drive component, a detection component, and a moving component, enables segmented non-contact detection when inspecting mining wire ropes. For long-length wire ropes, segmented detection can achieve axial segment-by-segment scanning, avoiding missed detections at distant ends due to signal attenuation and interference superposition during continuous long-distance detection, and ensuring that every segment from the beginning to the end of the wire rope is accurately covered.

[0015] 2. This utility model, through the design of the detection components, allows the detection probe device to cover all directions around the circumference of the wire rope when rotating 360° around it. This avoids the omission of defects on the inner side of the rope strands or the side away from the probe due to obstructed vision when performing fixed unidirectional detection. At the same time, when performing segmented detection, each segment has a clear length mark, and the defect detection results will be directly associated with the specific segment number. The defect location can be directly located based on the segment number, which greatly shortens the repair and search time. Attached Figure Description

Detailed Implementation

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0021] Please see Figures 1-3 A non-contact testing device for mining wire ropes includes a main body 11 and symmetrically arranged adjustment frames 12 on the main body 11. A support frame 13 adjacent to the adjustment frame 12 is arranged on the main body 11, and support rollers 14 are arranged on both the support frame 13 and the adjustment frame 12. A segmented rotation testing mechanism is arranged on the main body 11 between the support rollers 14. The segmented rotation testing mechanism includes a drive component 2 and a moving component 4 arranged on the main body 11 adjacent to the support frame 13 for segmented testing of mining wire ropes. A testing component 3 is arranged between the drive component 2 and the moving component 4 for flipping testing to achieve all-round testing.

[0022] like Figure 2 As shown, the drive assembly 2 includes a motor 21 fixed to the bottom surface of the main body 11 and a drive shaft 22 disposed thereon. The main body 11 is provided with a first support plate 26 adjacent to the support frame 13, and a first synchronous pulley 23 and a second synchronous pulley 25 are disposed on the first support plate 26 and the drive shaft 22. A synchronous belt 24 passing through the main body 11 is disposed between the first synchronous pulley 23 and the second synchronous pulley 25. The first hexagonal plate 31 is fixed to the second synchronous pulley 25 and passes through the first support plate 26.

[0023] In use, the mining wire rope is passed between the two support rollers 14, and the drive assembly 2 drives the detection assembly 3 to rotate, so as to perform all-round detection on the wire rope. Specifically, the start motor 21 drives the first synchronous pulley 23 on the drive shaft 22 to rotate, and the second synchronous pulley 25 rotates under the connection of the synchronous belt 24.

[0024] like Figure 2 and Figure 3As shown, the detection component 3 includes a first hexagonal plate 31 and a second hexagonal plate 32, and the second hexagonal plate 32 is thicker than the first hexagonal plate 31. A plurality of rotatably connected rods 33 are arranged between the first hexagonal plate 31 and the second hexagonal plate 32, and a detection probe device 37 is arranged between the rods 33. A rope hole 35 is opened on the second hexagonal plate 32, and a first hydraulic cylinder 34 is arranged on the second hexagonal plate 32 with the rope hole 35 as the center of symmetry. A clamp 36 is provided at the piston end of the first hydraulic cylinder 34.

[0025] When the second synchronous pulley 25 starts to rotate, it will drive the first hexagonal plate 31 and the second hexagonal plate 32 to rotate, which in turn drives the detection probe device 37 on the connecting rod 33 to perform non-contact all-round detection of the wire rope, thereby avoiding the risk of missed detection on one side and improving the traditional wire rope rotation detection, which is prone to knotting.

[0026] like Figure 2 As shown, the moving component 4 includes a slide groove 43 opened on the main body 11, a second hydraulic cylinder 41 is provided on the bottom surface of the main body 11, and a second support plate 42 is fixed at the piston rod end of the second hydraulic cylinder 41, which passes through the slide groove 43 and is rotatably connected to the second hexagonal plate 32.

[0027] When the detection probe device 37 is constantly rotating, the second hydraulic cylinder 41 is activated to drive the second hexagonal plate 32 on the second support plate 42 to move along the slide groove 43. At the same time, the two first hydraulic cylinders 34 are activated to drive the clamp 36 to clamp the wire rope. Then, the reciprocating motion of the second hydraulic cylinder 41 makes the wire rope form a segmented detection, which can quickly detect defects such as cracks and debris on the surface of the wire rope and avoid safety hazards during use.

[0028] It is important to understand that when the second hexagonal plate 32 moves the wire rope closer to the first hexagonal plate 31, the clamp 36 clamps the wire rope. When the second hexagonal plate 32 moves the wire rope away from the first hexagonal plate 31, the clamp 36 remains relaxed. This completes the movement of the wire rope in one operation. The combination of these two methods forms a three-dimensional full-coverage detection system with axial segmentation and circumferential rotation, completely eliminating axial and circumferential blind spots. This is the core prerequisite for ensuring zero missed detection of wire rope defects.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
