Description

Technical Field

[0001] This utility model relates to the field of wire rope performance testing technology, specifically to a mining wire rope performance testing device. Background Technology

[0002] In the complex system of the mining industry, mining wire ropes are like an invisible yet resilient "lifeline," running through every key link of mine production and serving as a core component to ensure the safe and efficient operation of mines. From deep underground ore extraction to surface material transportation, mining wire ropes play an indispensable role in various types of mining equipment.

[0003] During the manufacturing process, wire ropes need to undergo performance sampling inspections. The performance test is generally a breaking tensile test, which involves pulling the wire rope sample until it breaks, recording the maximum breaking tensile force, and determining whether its load-bearing capacity meets the standards.

[0004] However, the moment it breaks, it releases enormous elastic potential energy, and the end of the wire rope will rebound and swing at high speed, which can easily hit people or equipment. Moreover, when it breaks, it may be accompanied by the ejection of rope strands, clamp fragments or end fixing parts, causing puncture and impact injuries, which can easily pose a danger to the surrounding inspection personnel. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a mining wire rope performance testing device to solve the technical problem that wire rope breakage during tensile testing can easily cause harm to surrounding personnel.

At the same time, the tension detector 7 can detect the tension when the wire rope breaks, so the performance of the wire rope can be detected by the tension feedback.

[0024] Reference Figures 1-3The protective mechanism includes a protective tube 10, a protective ring 11, a first protective mechanism, and a second protective mechanism. The protective tube 10 is disposed between the top plate 2 and the base 1. The protective ring 11 is fixedly disposed on the outer wall of the protective tube 10. The support column 3 passes through the protective ring 11 and is fixedly connected to the protective ring 11. The first protective mechanism is disposed on the protective tube 10 and is used to protect the gap between the protective tube 10 and the top plate 2. The second protective mechanism is disposed on the bottom side of the protective tube 10 and is used to protect the gap between the protective tube 10 and the fixed base 6. The first protective mechanism includes a second protective mechanism. A sleeve 12 and a support spring 14 are provided. The first sleeve 12 is fitted onto the protective tube 10. A first positioning ring 13 is fixedly provided on the top side wall of the first sleeve 12. The support spring 14 is fitted onto the first sleeve 12. The two ends of the support spring 14 are fixedly connected to the first positioning ring 13 and the protective ring 11, respectively. Specifically, the support spring 14 can push the top end of the first protective sleeve to contact the top plate 2, while the bottom end of the first protective sleeve is fitted onto the protective tube 10, thereby protecting the gap between the wire rope and the protective tube 10 and the top plate 2.

[0025] Reference Figures 1-4 The second protective mechanism includes a second sleeve 15, a second positioning ring 16, and a positioning mechanism. The second sleeve 15 is slidably disposed inside the protective tube 10. The second positioning ring 16 is fixedly disposed at the bottom of the outer wall of the second sleeve 15. The positioning mechanism is disposed between the second positioning ring 16 and the fixed seat 6 and is used to position the fixed seat 6 and the second positioning ring 16. Specifically, the bottom end of the second protective sleeve can be fixed to the fixed seat 6 by the positioning mechanism, so that the second protective mechanism can protect the protective tube 10 and the fixed seat 6. In turn, the first protective sleeve, the second protective sleeve, and the protective tube 10 can protect the wire rope.

[0026] Reference Figure 4 and Figure 5The positioning mechanism includes a positioning groove 17, a first gear 19, a positioning block 20, and a synchronous rotation mechanism. Multiple positioning grooves 17 are formed on the inner wall of the fixed groove 8. A rotating shaft 18 is rotatably mounted within each positioning groove 17. The first gear 19 is coaxially and fixedly mounted on the rotating shaft 18. The positioning block 20 is fixedly mounted on the side wall of the first gear 19. The synchronous rotation mechanism is mounted on the fixed base 6 and is used to drive the multiple first gears 19 to rotate synchronously. The synchronous rotation mechanism includes an annular groove and a drive ring 21. The annular groove is formed on the outer wall of the fixed base 6 and communicates with the positioning groove 17. The drive ring 21 is rotatably mounted within the annular groove, and its inner wall is fixedly mounted... A first gear ring is provided, which meshes with the first gear 19. A torsion spring 22 is fitted on the rotating shaft 18. The two ends of the torsion spring 22 are fixedly connected to the first gear 19 and the side wall of the positioning groove 17, respectively. The outer wall of the drive ring 21 is provided with anti-slip texture. Specifically, after the second positioning ring 16 is inserted into the fixing groove 8, the first gear ring can be rotated by the rotation of the drive ring 21. At the same time, the first gear 19 is rotated by the meshing of the first gear 19. Thus, the positioning block 20 can be inserted into the fixing groove 8 and abut against the top side wall of the second positioning ring 16, thereby achieving the fixation between the second protective sleeve and the fixing seat 6.

[0027] In this embodiment, during use, the operator inserts the wire rope through the protective tube 10 and pulls the first protective sleeve to fix both ends of the wire rope with the wire rope clamp 9. Afterwards, the operator releases the first protective sleeve, which is pushed by the support spring 14 to contact the top of the first protective sleeve with the top plate 2. Simultaneously, the bottom of the first protective sleeve is fitted onto the protective tube 10, thus protecting the gap between the wire rope and the protective tube 10 and the top plate 2. Then, the operator rotates the drive ring 21, which in turn rotates the first gear ring. Simultaneously, the meshing of the first gear 19 with the first gear 19 causes the first gear 19 to rotate, thereby causing the positioning block 20 to retract into the fixing groove 8. Afterwards, the operator... The operator inserts the second positioning ring 16 into the fixing groove 8 and releases the drive ring 21. At this time, the torsion spring 22 can drive the first gear 19 and the positioning block 20 to reset, so that the positioning block 20 can extend into the fixing groove 8 and abut against the top side wall of the second positioning ring 16, thereby fixing the second protective sleeve and the fixing seat 6. Thus, the first protective sleeve, the second protective sleeve and the protective tube 10 can protect the wire rope. Afterwards, the operator controls the hydraulic rod 5 to work, and the operation of the hydraulic rod 5 can pull the wire rope until it breaks. At the same time, the tension detector 7 can detect the tension when the wire rope breaks, so the performance of the wire rope can be detected through tension feedback.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
