[0020] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0021] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0022] In actual use, it is found that in the prior art, the fixation of steel wire ropes mostly relies on manual operation, which is not only time-consuming and laborious, but also difficult to ensure the consistency and reliability of each fixation, and it is easy to cause deviations in test results due to human factors. In today's increasingly automated era, the traditional manual fixation method has been difficult to meet the requirements of efficient, accurate and safe detection, especially when facing a large number of high-intensity steel wire rope detection tasks, its limitations are becoming more and more prominent. To solve the above problems, the following structure is specifically invented.

[0023] As Figures 1-9A wire rope strength detection device shown in the figure includes a detector 1 and a sliding table 2 arranged on the detector 1. Fixed disks 3 are fixedly connected to the top ends inside the detector 1 and the top end of the sliding table 2. Fixed cylinders 4 are fixedly connected to both ends inside the detector 1. Upper electric telescopic cylinders 5 are fixedly connected to the inner sides of the fixed cylinders 4. A cross 6 is fixedly connected between the output ends of the upper electric telescopic cylinders 5. Rope wheels 7 are rotatably connected to the front sides of the fixed disks 3. A pair of side grooves are formed through the side walls of the rope wheels 7. Locking blocks 8 are arranged on the side walls of the rope wheels 7. Middle grooves are formed through the side walls of the locking blocks 8. The locking blocks 8 are inserted into the side grooves through the middle grooves. Circular grooves are formed in the side walls of the fixed disks 3. A pair of tapered rings 9 with inclined surfaces are fixedly connected to the inner sides of the circular grooves. A number of locking grooves 10 with inclined surfaces are equidistantly formed in the side walls of the tapered rings 9 on the side far from the locking blocks 8. A sliding groove is formed in the side wall of the locking block 8. A limiting block 11 is slidably connected in the sliding groove. A tightening mechanism for pushing and then tightening the rope wheels 7 is arranged on the cross 6; An upper inclined groove 12 is formed in the side of the limiting block 11 close to the tapered ring 9. A lower inclined groove 13 is formed in the side wall of the limiting block 11. After the locking block 8 is pushed in, the lower inclined groove 13 is attached to the inclined surface of the locking groove 10. A limiting spring 14 is fixedly connected between the inner side of the sliding groove and the side wall of the limiting block 11. The inclined surface directions of the locking grooves 10 on the two fixed disks 3 are arranged in opposite directions. Only by rotating the two rope wheels 7 in two directions can the wire rope be locked. Otherwise, a phenomenon of one paying out and one taking in will occur. An outlet 15 is formed in the side wall of the rope wheel 7. Through the arrangement of the outlet 15, it is convenient to insert the wire rope wound on the rope wheel 7 into the middle groove; A rotating ring 26 is rotatably connected to the rear side of the fixed disk 3. A guide rod 27 is fixedly connected to the rear side of the locking block 8. The rear side of the guide rod 27 penetrates through the side wall of the fixed disk 3. A rear plate 28 is fixedly connected to the rear end of the guide rod 27. A return spring 29 is fixedly connected between the side wall of the rear plate 28 and the rotating ring 26. Through the arrangement of the guide rod 27 and the return spring 29, it is convenient to quickly push the locking block 8 to reset after unlocking; The tightening mechanism includes tightening motors 16. There are a pair of tightening motors 16. Fixed frames 17 are fixedly connected to both the upper and lower sides of the cross 6. The tightening motors 16 are fixedly connected to the inner sides of the fixed frames 17. The output ends of the tightening motors 16 pass through the rear sides of the fixed frames 17 and are fixedly connected to circular frames 18. A circular ring 19 is rotatably connected to the side wall of the circular frame 18. A number of push plates 20 are fixedly connected to the side wall of the circular ring 19 at equal intervals. A pair of positioning blocks 21 are fixedly connected to the outer wall of the locking block 8. An arc groove 22 is formed in the side wall of the circular frame 18. An arc-shaped block 23 is fixedly connected to the side wall of the circular ring 19; Both ends of the front side of the positioning block 21 are inclined. The rear ends of the several push plates 20 are set as smooth arc surfaces. The arc-shaped block 23 is rotatably connected to the inner side of the arc groove 22. Arc springs 24 are fixedly connected between both ends of the inner side of the arc groove 22 and the outer wall of the arc-shaped block 23; Pressure sensors 25 are fixedly connected to the side ends of the arc-shaped blocks 23, and the pressure sensors 25 are electrically connected to the tightening motor 16 through a controller; When performing a strength test on the steel wire rope, first insert one end of the steel wire rope into the middle groove on the upper rope wheel 7, pass through the outlet 15 and wind it around the rope wheel 7 (it should be noted here that the number of winding turns on the two rope wheels 7 is the same, and the number of winding turns is operated according to the detection regulations). Then wind the other end of the steel wire rope around the lower rope wheel 7, and then pass the other end of the steel wire rope through the outlet 15 and insert it into the middle groove (it should be noted here that due to the elasticity of the steel wire rope itself, the steel wire rope bent and inserted into the middle groove from the outlet 15 will be stuck between the outlet 15 and the inner side of the middle groove under its own elastic force, playing a certain supporting role. Therefore, when the steel wire rope is loosened, it will not fall off). Then, the upper electric telescopic cylinder 5 can be controlled to start, driving the cross 6 and the fixed frame 17 to move, and at the same time driving the ring 19 to move beside the locking block 8. At this time, if the push plate 20 is located beside the positioning block 21; Thus, under the action of the inclined surface of the positioning block 21 squeezing the arc surface of the push plate 20, the push plate 20 will flip up or down, driving the ring 19 to rotate on the side wall of the circular frame 18, and driving the arc-shaped block 23 to rotate in the arc groove 22. At the same time, since arc-shaped springs 24 are fixedly connected to both sides of the arc-shaped block 23, one side of the arc-shaped spring 24 will be compressed and the other side will be stretched. Then the push plate 20 is stuck beside the positioning block 21. Subsequently, with the continuous movement of the upper electric telescopic cylinder 5, the locking block 8 will be pushed to move, inserted into the circular groove on the fixed disk 3, and at the same time drive the limiting block 11 to move backward to one side. At this time, the inclined surface of the conical ring 9 will squeeze the upper inclined groove 12 on the limiting block 11, causing the limiting block 11 to slide into the chute and compress the limiting spring 14. Then, when the limiting block 11 moves out from beside one of the conical rings 9, the extrusion on the limiting block 11 will be released, and then under the elastic force of the limiting spring 14, the limiting block 11 will be pushed to reset and stuck at the rear end of the front conical ring 9. Subsequently, the locking block 8 continues to move, causing the limiting block 11 to be stuck in the locking groove 10 of the rear conical ring 9. At the same time, the locking block 8 tightly squeezes the steel wire rope inserted into the middle groove against the side wall of the rope wheel 7. During this process, the movement of the rope wheel 7 will drive the guide rod 27 and the rear plate 28 to move, and gradually stretch the return spring 29; Finally, the tightening motor 16 can be controlled to start and drive the circular frame 18 to rotate (it should be noted here that the rotation directions of the tightening motors 16 beside the two rope pulleys 7 are opposite). Then, the side end of the arc groove 22 on the circular frame 18 rotates to beside the arc-shaped block 23 and compresses the corresponding arc-shaped spring 24. Subsequently, the arc groove 22 pushes the arc-shaped block 23 to drive the ring 19 to rotate, and drives the positioning block 21 to move through the push plate 20. Then, it drives the locking block 8 and the rope pulley 7 to rotate on the side wall of the fixed disk 3, and at the same time drives the limit block 11 to rotate. At this time, the inclined plane of the locking groove 10 will squeeze the lower inclined groove 13 on the limit block 11, and then compress the limit block 11 into the sliding groove and compress the limit spring 14. Subsequently, when the limit block 11 moves to beside the other locking groove 10, it will be pushed to reset under the elastic force of the limit spring 14 and get stuck in the corresponding locking groove 10. Repeating this process, the steel wire rope can be tightly wound around the rope pulley 7, and the locking groove 10 will restrict the reverse rotation and forward movement and reset of the limit block 11, thereby restricting the reverse rotation of the rope pulley 7 and the forward movement and reset of the locking block 8, avoiding the release of the winding of the steel wire rope. During this process, the pressure sensor 25 in the arc groove 22 will push the arc-shaped block 23 to drive the locking block 8 and the rope pulley 7 to rotate and wind the steel wire rope. Then, as the steel wire rope is wound closer and closer, the winding force will become larger and larger. Thus, the pressure transmitted by the arc-shaped block 23 to the pressure sensor 25 will become larger and larger. When the pressure sensor 25 detects that the pressure reaches the specified value, it will automatically control the tightening motor 16 to stop running, so as to wind the steel wire rope to the specified strength and ensure the accuracy of the detection result. Then, control the upper electric telescopic cylinder 5 to drive the cross 6 to move forward. Subsequently, the testing machine 1 can be controlled to start and drive the rope pulley 7 at the bottom to move downward to detect the strength of the steel wire rope.

[0024] In summary, through the design of the above structure, the tester only needs to wind the steel wire rope around the two rope pulleys 7 and pass the two ends of the steel wire rope through the middle groove of the locking block 8, then the device can be controlled to start, automatically clamp the two ends of the steel wire rope first, and then drive the rope pulleys 7 to rotate in opposite directions, so as to tightly wind the steel wire around the two rope pulleys 7. And a pressure sensor 25 is equipped to fix the steel wire rope on the rope pulley 7 according to the specified winding force. Then, the tensile testing machine 1 can be controlled to start to automatically detect the strength of the steel wire rope. Thus, there is no need for the tester to tighten and fix, greatly improving the detection efficiency of the device and saving time and effort.

[0025] On the basis of the above embodiment, it is found during use that although the steel wire rope can be automatically locked, after the detection is completed, it still needs to be removed by the tester, which is rather troublesome. To solve the above problem, the above structure is further improved.

[0026] An L-shaped groove is provided inside the locking block 8, and the L-shaped groove is connected to the slide. The inside of the slide is rotatably connected to the first guide roller 30 relative to the position next to the L-shaped groove. The second guide roller 31 is rotatably connected at the corner of the L-shaped groove. The inside of the L-shaped groove is slidably connected to the unlocking rod 32. A pull rope 33 is fixedly connected to the side wall of the limit block 11, and a third guide roller 34 is rotatably connected to the side of the L-shaped groove away from the slide. The other end of the pull rope 33 passes through the outer walls of the first guide roller 30, the second guide roller 31 and the third guide roller 34 in sequence and is fixedly connected to the side wall of the unlocking rod 32. An unlocking spring 35 is fixedly connected between the inside of the L-shaped groove and the side wall of the unlocking rod 32. An unlocking ring 36 is provided on the outer wall of the circular frame 18, and a pair of lower electric telescopic cylinders 40 are fixedly connected to the inner side of the fixed frame 17. The output ends of the lower electric telescopic cylinders 40 pass through the side walls of the fixed frame 17 and are fixedly connected to the side walls of the unlocking ring 36; When the wire rope strength test is completed, the upper electric telescopic cylinder 5 can be controlled to start driving the ring 19 on the cross 6 to move to the side of the locking block 8, and then the lower electric telescopic cylinder 40 can be controlled to start pushing the unlocking ring 36 to the rear side, and then the unlocking ring 36 will push the unlocking rod 32 to slide in the L-shaped groove and gradually compress the unlocking spring 35, while driving the pull rope 33 to move. At this time, the pull rope 33 will pull the limit block 11 to slide into the sliding under the guidance of the third guide roller 34, the second guide roller 31 and the first guide roller 30. The upper electric telescopic cylinder 5 can then be controlled to start resetting. During this process, the elastic force of the reset spring 29 will pull the rear plate 28 and the guide rod 27 to reset, thereby pulling the locking block 8 to follow the ring 19 out of the circular groove. At the same time, the tightening motor 16 can be controlled to start reversing, gradually releasing the winding of part of the wire rope. Finally, after the locking block 8 is reset, the upper electric telescopic cylinder 5 can be controlled to reset, and the broken wire rope can be pulled out.

[0027] In summary, through the design of the above structure, the locking and fixing of the wire rope can be automatically released after the detection is completed, which facilitates the quick removal of the wire rope and further improves the convenience performance of the device.

[0028] Based on the above embodiment, it was found during use that the extrusion locking distance of the locking block 8 in the above structure is fixed, and thus can only lock steel wire ropes of the same diameter, which is quite limited. In order to solve the above problem, the above structure was further improved.

[0029] An extrusion block 37 is provided on the inner side of the middle groove. A screw rod 38 is threadedly connected through the side wall of the locking block 8. Here, it should be noted that when the circular frame 18 moves to the side of the locking block 8, the screw rod 38 will insert into the circular frame 18, so it will not hinder the normal movement of the circular frame 18. And the screw rod 38 is rotatably connected to the side wall of the extrusion block 37. When testing wire ropes of different specifications, the screw rod 38 can be rotated. Since the screw rod 38 is threadedly connected through the locking block 8, the screw rod 38 will spiral backward, and at the same time drive the extrusion block 37 to slide in the middle groove, thereby changing the position of the extrusion block 37, so that wire ropes of smaller specifications can be extruded and locked, improving the general performance of the device. A scale groove 39 is provided at the top of the middle groove. Through the setting of the scale groove 39, it is convenient to observe the adjustment position of the extrusion block 37 and accurately adjust the extrusion block 37 to the specified position.

[0030] In summary, through the design of the above structure, the locking position of the tightening mechanism can be adjusted according to the diameter of the wire rope to be detected, so that wire ropes of different diameters can be used, further improving the application range of the device.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention.

[0032] Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
