Description

Technical Field

[0001] This utility model belongs to the field of wire rope local deformation measurement technology, specifically a wire rope local deformation measurement device based on a dial indicator. Background Technology

[0002] Currently, commercially available wire rope local deformation measurement devices based on dial indicators use dual transverse sliding rails to drive the wire rope clamp, enabling fixation and measurement positioning of the wire rope at different locations. Simultaneously, the dial indicator, driven by a two-dimensional moving mechanism composed of longitudinal and transverse sliding rails, can flexibly adjust the contact position between the measuring probe and the wire rope surface to meet deformation detection needs in different directions and locations. While this structural design effectively achieves high-precision measurement of local deformation of wire ropes, it reveals significant drawbacks in practical use: when idle, the multiple sets of sliding rails and supporting structures result in a large overall device size, occupying substantial storage space and posing problems such as susceptibility to damage during transportation and inconvenience in on-site handling. Therefore, we propose a wire rope local deformation measurement device based on a dial indicator. Utility Model Content

[0018] Please see Figure 1-3A device for measuring local deformation of a steel wire rope based on a dial indicator includes a base 13. A storage box 11 is placed on the front side of the base 13, and a sponge liner 12 is fixedly installed inside the storage box 11. A set of first mounting seats 16 are placed on the left and right sides of the top of the base 13. A clamping column 18 is rotatably installed in the first mounting seat 16 via a rotating shaft. A first through hole and a second through hole are opened through the front side of the first mounting seat 16. A first threaded hole is opened on the front side of the clamping column 18. A first bolt 17 is rotatably installed in the first through hole and the first threaded hole. The first bolt 17 is screwed through the first through hole of the first mounting seat 16 and into the first threaded hole of the clamping column 18, thereby vertically fixing the clamping column 18 in the first mounting seat 16. A second mounting seat 22 is placed on the rear side of the top of the base 13. A guide rail 23 is rotatably installed inside the second mounting seat 22 via a rotating shaft. A second threaded hole is opened on the left side of the guide rail 23, and a third threaded hole is opened through the left side of the second mounting seat 22. A second bolt 32 is rotatably installed in the through hole and the fourth through hole, the third through hole and the second threaded hole. The second bolt 32 is threaded through the third through hole of the second mounting base 22 and screwed into the second threaded hole of the guide rail 23, thereby vertically fixing the guide rail 23 in the second mounting base 22. A dial indicator 29 is placed on the front side of the guide rail 23. The first bolt 17 corresponds to the second through hole, the second bolt 32 corresponds to the fourth through hole, and the dial indicator 29 corresponds to the sponge lining 12. A placement groove is opened through the right side of the clamping column 18. A third threaded hole is opened through the top of the placement groove. A locking bolt 19 is screwed into the third threaded hole. The two ends of the wire rope are placed in the placement grooves of the two sets of clamping columns 18 respectively. Then the locking bolt 19 is tightened, thereby pressing and fixing the ends of the wire rope, and thus fixing them in the placement groove of the clamping column 18. A base plate 1 is fixedly installed at the bottom of the base 13, and a storage box 11 is fixedly installed on the top front side of the base plate 1.

[0019] The top of the base 13 has a first slide groove and a second slide groove. A bidirectional lead screw 14 and a first screw 2 are rotatably mounted in the first and second slide grooves, respectively. Two sets of first internal thread sliders 15 are evenly screwed onto the outer wall of the bidirectional lead screw 14. A first mounting seat 16 is fixedly mounted on the top of the first internal thread sliders 15. A second internal thread slider 21 is screwed onto the outer wall of the first screw 2. A second mounting seat 22 is fixedly mounted on the top of the second internal thread slider 21. The right sides of both the bidirectional lead screw 14 and the first screw 2 pass through the right side of the base 13 and are respectively connected to a third handwheel 3. The first handwheel 1 and the second handwheel 3, when rotated, drive the double-acting screw 14 to rotate. The double-acting screw 14 drives the two sets of first internal thread sliders 15 to move inward synchronously. This causes the first internal thread sliders 15 to drive the clamping columns 18 to move synchronously through the first mounting base 16, thereby changing the distance between the two sets of clamping columns 18. This allows the clamping columns 18 to clamp the wire rope at different positions. The front side of the guide rail 23 has a third slide groove, in which a second screw 25 is rotatably mounted. The outer wall of the second screw 25 is screwed with a third internal thread slider. 27. A support sleeve 28 is fixedly installed on the front side of the third internal thread slider 27. The support sleeve 28 corresponds to the sponge liner 12. The dial indicator 29 is fixedly installed inside the support sleeve 28 and located between the two sets of clamping posts 18. The measuring head of the dial indicator 29 passes through the bottom of the support sleeve 28. The top of the second screw 25 passes through the top of the guide rail 23 and is connected to the first handwheel 26. By rotating the first handwheel 26, the second screw 25 is rotated, which in turn drives the third internal thread slider 27 to move downward, thereby driving the dial indicator 29 to move downward through the support sleeve 28. This allows the measuring head of the dial indicator 29 to come into contact with the top of the wire rope. Then, by rotating the second handwheel 3, the first screw 2 is rotated, which in turn drives the second internal thread slider 21 to move left and right. This causes the second internal thread slider 21 to move the guide rail 23 to the left and right sides via the second mounting base 22, which in turn causes the dial indicator 29 on the front side of the guide rail 23 to move left and right. This allows the measuring head of the dial indicator 29 to slide on the top of the wire rope, thereby enabling the measurement of local deformation of the wire rope. A handle 24 is fixedly installed on the rear side of the guide rail 23.

[0020] Working principle: The first bolt 17 passes through the first through hole of the first mounting base 16 and is screwed into the first threaded hole of the clamping column 18, thereby vertically fixing the clamping column 18 inside the first mounting base 16. The second bolt 32 passes through the third through hole of the second mounting base 22 and is screwed into the second threaded hole of the guide rail 23, thereby vertically fixing the guide rail 23 inside the second mounting base 22. The two ends of the wire rope are placed in the placement slots of the two sets of clamping columns 18 respectively, and then the locking bolt 19 is tightened, thereby pressing and fixing the ends of the wire rope in place in the placement slots of the clamping column 18. By rotating the third handwheel 31, the bidirectional screw 14 is rotated, which drives the two sets of first internal thread sliders 15 to move inward synchronously, thereby causing the first internal thread sliders 15 to drive the clamping column 18 through the first mounting base 16. The two sets of clamping columns 18 move synchronously to change the distance between them, allowing the clamping columns 18 to clamp the wire rope at different positions. Rotating the first handwheel 26 drives the second screw 25 to rotate, which in turn drives the third internal thread slider 27 to move downwards. This, in turn, drives the dial indicator 29 downwards via the support sleeve 28, bringing the dial indicator 29's probe into contact with the top of the wire rope. Then, rotating the second handwheel 3 drives the first screw 2 to rotate, which in turn drives the second internal thread slider 21 to move left and right. This causes the second internal thread slider 21 to move left and right via the second mounting base 22, which in turn moves the dial indicator 29 on the front side of the guide rail 23 left and right, allowing the dial indicator 29's probe to slide on the top of the wire rope, thus enabling local deformation measurement of the wire rope.

[0021] Unscrew the first bolt 17 and rotate the clamping column 18 inward by 90 degrees. Then, thread the first bolt 17 through the second through hole of the first mounting base 16 and screw it into the first threaded hole of the clamping column 18 to fix the clamping column 18. Similarly, unscrew the second bolt 32 and rotate the guide rail 23 forward by 90 degrees. Then, thread the second bolt 32 through the fourth through hole of the second mounting base 22 and screw it into the second threaded hole of the guide rail 23 to fix the guide rail 23. When the guide rail 23 is rotated forward by 90 degrees, the support sleeve 28 and the dial indicator 29 located on the front side of the guide rail 23 will be placed inside the sponge liner 12 to store and protect the dial indicator 29. At the same time, the handle 24 will be located above the entire device as the guide rail 23 is rotated. At this time, the device can be lifted by the handle 24 to improve the portability of the device.
