Description

Technical Field

[0001] The present invention relates to the technical field of stainless steel wire ropes, and particularly to a stainless steel wire rope limiting and clamping device. Background Art

[0002] When using a stainless steel wire rope, one end of it needs to be bent into a loop so that the stainless steel wire rope can be sleeved outside an object. Therefore, it is necessary to limit and clamp one end of the stainless steel wire rope. When limiting and clamping the stainless steel wire rope, a limiting and clamping device is required. A Chinese patent discloses a stainless steel wire rope limiting and clamping device (authorized announcement number CN212717814U). This patented technology mentions the existing stainless steel wire rope limiting and clamping device, which has a simple structure and limits and clamps the stainless steel wire rope individually, resulting in scattered clamping and fixing points, easily causing the stainless steel wire rope to separate from the clamping and fixing device, thus reducing the fastening effect on the wire rope. Therefore, it fixes three U-shaped hoop rings together through a fastening card plate, and also engages and clamps the outer surface of the stainless steel wire rope through meshing grooves on the inner surface of the clamping groove and the outer surface of the inner side of the fastening device, thereby increasing the friction between the stainless steel wire rope and the fastening card plate and the fastening device, and increasing the clamping effect on the stainless steel wire rope. However, in the "Safety Technical Regulations for Installation, Use and Dismantling of Tower Cranes in Construction" (JGJ196 - 2010), it is stipulated that there should be an interval distance between each limiting and clamping device, and the interval distance should not be less than six times the diameter of the wire rope. Therefore, its three-in-one structure cannot achieve a good limiting and clamping function, and the bolts it uses have the same problem as the nuts in conventional clamping devices. During long-term use, the bolts or nuts are prone to loosening, thus greatly reducing the limiting and clamping ability. Therefore, those skilled in the art provide a stainless steel wire rope limiting and clamping device to solve the problems raised in the above background art. Summary of the Invention

[0029] Please refer to Figures 1 to 12, in the embodiment of the present invention, a stainless steel wire rope limiting and clamping device includes a plurality of first wire rope limiting and clamping mechanisms 2 uniformly installed outside the stainless steel wire rope 1, and further includes a second wire rope limiting and clamping mechanism 3 installed outside the stainless steel wire rope 1 in front of the first wire rope limiting and clamping mechanism 2. The first wire rope limiting and clamping mechanism 2 includes a fixed seat 4, and a U-shaped ring 5 is movably passed through the inside of the fixed seat 4. The stainless steel wire rope 1 is installed between the fixed seat 4 and the U-shaped ring 5. Threads 6 are provided at both the left and right ends of the outer surface of the U-shaped ring 5, and spring washers 7 are movably installed at both the left and right ends of the outside of the U-shaped ring 5. The spring washers 7 are in contact with the lower surface of the fixed seat 4. Fixed nuts 8 are threadedly connected below the spring washers 7 at both the left and right ends of the outside of the U-shaped ring 5, and the fixed nuts 8 are in contact with the lower surface of the spring washers 7; the stainless steel wire rope 1 can be limited and clamped by the first wire rope limiting and clamping mechanism 2. By turning the fixed nut 8 with a torque wrench, when the torque is within the set range, it means that the fixed seat 4 and the U-shaped ring 5 have firmly fixed the stainless steel wire rope. At this time, turn the fixed nut 8 (the fixed nut 8 is a hexagonal nut) to make one of its sides parallel to the front surface of the fixed seat 4.

[0030] In Figures 1 to 9In the middle: Two protective components 9 are symmetrically arranged on the front surface of the fixed seat 4. The protective component 9 includes a protective seat 10. The protective seat 10 is installed on the front surface of the fixed seat 4. Two mounting rods 11 are symmetrically and movably penetrated and connected to the lower surface of the protective seat 10. The rear ends of the two mounting rods 11 are jointly installed with a mounting plate 12. The mounting plate 12 is movably attached to the front surface of the fixing nut 8. The upper end of the mounting rod 11 is movably penetrated and connected to a limiting rod 13. The limiting rod 13 is installed on the front and rear side surfaces inside the protective seat 10. A threaded rod 14 penetrates and is threadedly connected below the limiting rod 13 inside the mounting rod 11. A worm gear 15 is installed outside the front end of the threaded rod 14. The rear end of the threaded rod 14 is rotatably connected to a first mounting block 16. The first mounting block 16 is installed on the rear surface inside the protective seat 10. A worm 17 is installed above the worm gear 15 inside the protective seat 10. The worm gear 15 is meshed with the worm 17. A docking block 18 is installed between the two worms 17. The left end of the left worm 17 is rotatably connected to a second mounting block 19. The second mounting block 19 is installed on the left side surface inside the protective seat 10. The right end of the right worm 17 is installed with an adjusting rod 20. The adjusting rod 20 movably penetrates the right side surface of the protective seat 10. A first adjusting plate 21 is installed outside the adjusting rod 20. A number of limiting sleeves 22 are evenly installed on one side surface of the first adjusting plate 21. One end of the limiting sleeve 22 is movably penetrated and connected to a telescopic rod 23. One end of the telescopic rod 23 is installed with a telescopic block 24. The telescopic block 24 is slidably connected inside the limiting sleeve 22. A limiting spring 25 is installed on one side surface of the telescopic block 24. One end of the limiting spring 25 is installed on one side surface inside the limiting sleeve 22. A second adjusting plate 26 is movably installed on the outside of the first adjusting plate 21 on one side of the adjusting rod 20. One end of the telescopic rod 23 is connected to the second adjusting plate 26. A number of docking rods 27 are evenly installed on one side surface of the second adjusting plate 26. A number of docking sleeves 28 are evenly installed on the rear surface of the protective seat 10. The number of docking rods 27 is equal to the number of docking sleeves 28; In the normal state, the docking rod 27 is movably located inside the docking sleeve 28. By pulling the second adjusting plate 26 outwards to make the docking rod 27 move out of the inside of the docking sleeve 28, the adjusting rod 20 can be rotated, so as to drive the mounting rod 11 to move backward, and then drive the mounting plate 12 to fit one side of the fixing nut 8, so as to avoid the fixing nut 8 falling off due to vibration in the future. The helix angle of the worm 17 is less than 3°29'11" (i.e., the service factor is 0.6). In the static state, the worm gear 15 and the worm 17 are self-locking. At this time, the worm 17 cannot be rotated through the worm gear 15, and only the worm gear 15 can be rotated through the worm 17.

[0031] In Figure 1 、 Figures 10 to 12In Chinese: The second steel wire rope limiting and clamping mechanism 3 includes a first limiting seat 29 and a second limiting seat 30. The first limiting seat 29 and the second limiting seat 30 are jointly installed outside the stainless steel wire rope 1. Connecting bolts 31 are movably penetrated through the four corners of the first limiting seat 29, and the right ends of the connecting bolts 31 are threadedly connected inside the second limiting seat 30. Two semi-circular grooves 32 are symmetrically formed on one side surface of both the first limiting seat 29 and the second limiting seat 30. Two limiting plates 33 are symmetrically and slidably connected inside the first limiting seat 29. The limiting plates 33 are movably located in the left semi-circular grooves 32. A limiting bolt 34 is rotatably connected to one side surface of the limiting plate 33. The limiting bolt 34 penetrates through and is threadedly connected to the first limiting seat 29. Slide rods 35 are installed on both the front and rear sides of the limiting bolt 34 on one side surface of the limiting plate 33. The slide rods 35 movably penetrate through the first limiting seat 29. A pin 36 is jointly and movably passed through the inside of the limiting bolt 34 and the two slide rods 35; The second steel wire rope limiting and clamping mechanism 3 can limit and clamp the stainless steel wire rope 1. The limiting bolt 34 can be rotated with an inner hexagon wrench to drive the limiting plate 33 to approach the stainless steel wire rope 1 and fix it. At this time, the staff can slightly rotate the limiting bolt 34 again to make the through hole on it and the through hole on the slide rod 35 be on the same horizontal line, so that the pin 36 can be inserted into the limiting bolt 34 and the slide rod 35 and fixed.

[0032] The working principle of the present invention is as follows: When clamping and fixing the stainless steel wire rope 1, the staff can first bend one end of the stainless steel wire rope 1 into two segments, put a U-shaped ring 5 on the outside of the stainless steel wire rope 1 and pass it through the fixing seat 4, and then install a spring washer 7 and a fixing nut 8 in sequence. Use a torque wrench to rotate the fixing nut 8. When the torque is within the required range, the staff can slightly rotate the fixing nut 8 again so that one side of the fixing nut 8 is parallel to the front surface of the fixing seat 4. Then the staff can pull the second adjusting plate 26 outwards so that the docking rod 27 moves out of the inside of the docking sleeve 28, and then the adjusting rod 20 can be rotated. The adjusting rod 20 drives the worm 17 to rotate, the worm 17 drives the worm wheel 15 to rotate, the worm wheel 15 drives the threaded rod 14 to rotate, and the mounting rod 11 engaged with the threaded rod 14 will drive the mounting plate 12 to move backward until it fits against one side of the fixing nut 8. In this way, when the entire stainless steel wire rope 1 vibrates, the fixing nut 8 cannot rotate due to vibration and thus cannot fall off, ensuring the firmness of the fixation. At this time, the staff can release the second adjusting plate 26 to drive the docking rod 27 to insert into the docking sleeve 28, and thus one first wire rope limiting and clamping mechanism 2 is installed. Two first wire rope limiting and clamping mechanisms 2 are installed respectively at positions where the distance from the previous first wire rope limiting and clamping mechanism 2 is six times the diameter of the stainless steel wire rope 1 according to the above method; a second wire rope limiting and clamping mechanism 3 is installed at the rear end of each first wire rope limiting and clamping mechanism 2. The first limiting seat 29 and the second limiting seat 30 are put on the outside of the stainless steel wire rope 1 and fixed with a connecting bolt 31. Then rotate the limiting bolt 34 so that the limiting plate 33 firmly presses against the stainless steel wire rope 1. At this time, the limiting bolt 34 can be slightly rotated again so that the through hole on it and the through hole on the sliding rod 35 are on the same horizontal line. In this way, a pin 36 can be inserted into the limiting bolt 34 and the sliding rod 35 and fixed, thus completing the installation of the second wire rope limiting and clamping mechanism 3.
