Detailed Implementation
[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0025] like Figures 1-6As shown, this utility model provides a simple auxiliary wheel adjustment and fixing mechanism, including an auxiliary wheel 1, an auxiliary wheel cross plate 2, two auxiliary wheel side plates 3, an angle adjustment plate 4, a long hexagon socket screw 5, an upper anti-loosening nut 6, an upper anti-loosening washer 7, a lower anti-loosening washer 8, a lower anti-loosening nut 9, two small copper sleeves 10, a wheel axle 11, six small screws 12, six spring washers 13, and six large washers 14. The auxiliary wheel side plates 3 have, in sequence, vertical limiting holes 301, central rectangular limiting holes 302, and flat shaft limiting holes 303. The two ends of the angle adjustment plate 4 are slidably installed in the vertical limiting holes 301, and the two ends of the auxiliary wheel cross plate 2 are fixedly installed in the central rectangular limiting holes 302 of the two auxiliary wheel side plates 3. The axle 11 passes sequentially through an auxiliary wheel side plate 3, a small copper sleeve 10, an auxiliary wheel 1, another small copper sleeve 10, and another auxiliary wheel side plate 3. Both ends of the axle 11 are fixed within the flat shaft limiting holes 303, positioning the auxiliary wheel 1 between the two auxiliary wheel side plates 3. Angle adjustment plate 4 has an angle positioning threaded hole 403, and a center through hole 202 is located at the center of the auxiliary wheel cross plate 2. A long internal hexagon screw 5 passes sequentially through the angle positioning threaded hole 403, an upper anti-loosening nut 6, an upper anti-loosening washer 7, the center through hole 202, a lower anti-loosening washer 8, and a lower anti-loosening nut 9. The upper anti-loosening nut 6 and upper anti-loosening washer 7 are installed on the side of the auxiliary wheel cross plate 2 facing the angle adjustment plate 4, and the lower anti-loosening washer 8 and lower anti-loosening nut 9 are installed on the side of the auxiliary wheel cross plate 2 facing the auxiliary wheel 1. This ensures that the lower surface of the lower anti-loosening nut 11 is above the thread of the long internal hexagon screw 5. An additional anti-loosening nut and anti-loosening washer can be added between the upper anti-loosening nut 6 and the angle adjusting plate 4 to make the structure more stable and safer. Both ends of the auxiliary wheel cross plate 2 are provided with rectangular positioning steps 201, which respectively engage with the central rectangular limiting holes 302 of the two auxiliary wheel side plates 3. Both ends of the angle adjusting plate 4 are provided with rectangular limiting bosses 402, which are the same width as the vertical limiting holes 301, and respectively engage with the vertical limiting holes 301 of the two auxiliary wheel side plates 3. The rectangular limiting bosses 402 on both sides of the angle adjusting plate 4 can slide within the vertical limiting holes 301 of the auxiliary wheel side plates 3. The rectangular positioning step 201 has a side threaded hole 203 on its side, the rectangular limiting boss 402 has a side fixing threaded hole 404 on its side, and the wheel axle 11 has axial threaded holes 1103 at both ends. The small screw 12 passes through the spring washer 13 and the large washer 14 in sequence and is driven into the side threaded hole 203, the side fixing threaded hole 404 or the axial threaded hole 1103 to fix the auxiliary wheel cross plate 2, the angle adjusting plate 4 and the wheel axle 11 to the auxiliary wheel side plate 3.
[0026] The auxiliary wheel 1 has a recessed arc surface 101, which can better surround the wire rope while maintaining a gap with it, and is suitable for wire ropes of different diameters. The wheel axle 11 includes two oppositely arranged flat shaft planes 1101 and two oppositely arranged flat shaft circular surfaces 1102. The flat shaft planes 1101 form a clearance fit with the two flat shaft limiting holes 303, and the flat shaft circular surfaces 1102 form a clearance fit with the auxiliary wheel 1, the two small copper sleeves 10, and the two flat shaft limiting holes 303. The two sides are then locked and fixed by small screws 12 passing through spring washers 13, large washers 14, and axial threaded holes 1103, so that the auxiliary wheel 1 and the auxiliary wheel side plate 3 are fixed as a whole. The auxiliary wheel 1 is fixed in the up, down, left, and right directions, but can rotate freely around the wheel axle 11.
[0027] The outer side of the auxiliary wheel side plate 3 is marked with 2mm interval scale lines 304 by laser. The scale lines 304 are located on both sides of the vertical limiting hole 301, and the scale lines 304 on the two auxiliary wheel side plates 3 are symmetrical. The side of the rectangular limiting boss 402 is provided with a positioning baseline 405, and the scale lines 304 of the positioning baseline 405 are parallel. The large shim 14 is provided with an observation hole 1401, and the position of the observation hole 1401 corresponds to the position of the positioning baseline. During positioning, the positioning baselines 405 on both sides of the angle adjusting plate 4 need to be aligned with the same scale lines 304 on the two auxiliary wheel side plates 3 respectively.
[0028] The angle adjustment plate 4 includes an adjustment part and a mounting part. An angle positioning threaded hole 403 is located in the adjustment part. The mounting part has two mounting holes 401. Two blind positioning pin holes 406 are provided on the side of the mounting part near the upper or lower housing of the wire rope flaw detector for inserting positioning pins 16 to position the mounting part between the mounting part and the upper or lower housing of the wire rope flaw detector. The mounting holes 401 are used to fix the mounting part to the upper or lower housing of the wire rope flaw detector using screws. The positions of the two mounting holes 401 and the two blind positioning pin holes 406 form a trapezoidal structure, which can better secure the angle adjustment plate 4.
[0029] like Figure 7As shown, this utility model can generally be used in pairs, arranged vertically. Each auxiliary wheel adjustment and fixing structure uses two sets of positioning pins 16, one end of which passes through the positioning pin blind hole 406 of the angle adjustment plate 4, and the other end of which passes through the upper or lower shell of the wire rope flaw detector, thus positioning the angle adjustment plate 4 with the upper or lower shell of the wire rope flaw detector. Additionally, each angle adjustment plate 4 is provided with two mounting holes 401. Screws pass through the mounting holes 401 and are screwed into the upper or lower shell of the wire rope flaw detector to lock and fix it, achieving complete fixation of the angle adjustment plate 4 with the wire rope flaw detector. A long internal hexagon screw 5 passes through the angle positioning threaded hole 403 and connects to the upper anti-loosening nut 6 and the upper anti-loosening washer 7, then passes through the center through hole 202, the lower anti-loosening washer 8, and the lower anti-loosening nut 9 on the auxiliary wheel cross plate 2. The upper and lower nuts are not locked, and the upper anti-loosening nut 6 is not in contact with the support wheel cross plate 2 and the angle adjustment plate 4. Fix the angle adjusting plate 4 to the upper and lower housings of the wire rope flaw detector by passing screws through the mounting holes 401. Do not tighten the small screws 12 on both sides of the angle adjusting plate 4 initially. Adjust the overall position of the auxiliary wheel 1, the auxiliary wheel cross plate 2, and the auxiliary wheel side plate 3, i.e., the appropriate position of the auxiliary wheel 1 relative to the wire rope 15. Figure 8 As shown, ensure that the positioning baselines 404 on both sides of the angle adjustment plate 4, as visually observed through the observation hole 1401, are aligned with the corresponding scale lines 304 on the auxiliary wheel side plates 3. The upper and lower arc surfaces 101 should maintain a suitable gap with the wire rope 15 while effectively limiting its vibration. Then, tighten the upper anti-loosening nut 6, the lower anti-loosening nut 9, and the small screws 12 located on the outer sides of the two auxiliary wheel side plates 3 to fix the position of the auxiliary wheel 1. If the portion of the long hexagonal socket screw 5 extending beyond the lower anti-loosening nut 9 interferes with the auxiliary wheel 1, the position of the long hexagonal socket screw 5 must be adjusted upwards first. When the wire rope 15 moves through the upper and lower arc surfaces 101, it can also drive the auxiliary wheel 1 to rotate. If it is necessary to replace the wire rope 15 with a different diameter, first loosen the upper anti-loosening nut 6 and the lower anti-loosening nut 9, then loosen the small screws 12 on both sides of the angle adjusting plate 4. Then, support the auxiliary wheel 1 on one side and adjust the relative position of the support wheel cross plate 2 with respect to the angle adjusting plate 4 on the other side. The auxiliary wheel side plate 3 slides up and down along the rectangular limiting boss 402. The long internal hexagon screw 5 passes through the central through hole 202 and is positioned appropriately, so that the auxiliary wheel 1 has a suitable gap with respect to the wire rope 15. This ensures that the wire rope 15 can pass through smoothly and also fully limits the vibration of the wire rope 15. Visually observe through the observation hole 1401 that the positioning baseline 404 on the left and right sides of the angle adjusting plate 4 is aligned with the same position scale line 304 on the auxiliary wheel side plate 3 on both sides. Then tighten the upper anti-loosening nut 6, the lower anti-loosening nut 9 and the small screws 12 on both sides of the angle adjusting plate 4.
[0030] The rectangular limiting bosses 402 at both ends of the angle adjusting plate 4 cooperate with the vertical limiting holes 301 on the left and right sides, which can limit the auxiliary wheel side plate 3 in the left and right directions, and also facilitate the adjustment of the auxiliary wheel 1 position along a fixed angle by the auxiliary wheel side plate 3, which is convenient for the installation and adjustment of the long hexagon socket screw 5. The design of the positioning baseline 405 can facilitate the alignment of the scale lines on both sides of the auxiliary wheel side plate 3, and prevent the auxiliary wheel from being uneven in height, which would affect the limiting and guiding function of the wire rope 15.
[0031] The long hex socket screw 5 passes through the angle positioning threaded hole 403 of the angle adjusting plate 4, which allows the long hex socket screw 5 to be fixed to the angle adjusting plate 4 as a whole. The long hex socket screw 5 passes through the upper anti-loosening nut 6, the upper anti-loosening washer 7, the center through hole 202 of the auxiliary wheel cross plate 2, the lower anti-loosening washer 8, and the lower anti-loosening nut 9 for locking engagement, which can ensure that the auxiliary wheel 1 and the long hex socket screw 5 are fixed as a whole, and can effectively prevent loosening due to the frequent vibration of the auxiliary wheel 1 by the wire rope 15. Another anti-loosening nut and anti-loosening washer can be added between the upper anti-loosening nut 6 and the angle adjusting plate 4 to make the structure more stable and safer.
[0032] With the frequent vibration of the wire rope, the force acting on the auxiliary wheel 1 is transmitted through the wheel axle 11 and the central rectangular limiting holes 302 of the auxiliary wheel side plates 3 on both sides to the rectangular positioning steps 201 on the side of the auxiliary wheel cross plate 2, which has a better impact resistance than the optical axis. The impact force acting on the auxiliary wheel 1 is finally transmitted through the wheel axle 11, the auxiliary wheel side plates 3, the auxiliary wheel cross plate 2, the long internal hex screws 5, the anti-loosening washers and anti-loosening nuts, and finally to the angle adjusting plate 4. By using the positioning pin 16, the angle adjusting plate 4 can be positioned and installed with the wire rope flaw detector, and the possibility of the angle adjusting plate moving when it is impacted can be effectively reduced.
[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
