[0021] See also Figure 1-4 As shown, a wire rope guide wheel for a filter press grab bucket is arranged in the grab bucket body, and includes a positioning frame 2, a positioning component 3 and an anti-wear component 4, and the positioning frame 2 is arranged inside the grab bucket body 1;

[0022] refer to Figure 1 , Figure 2 and Figure 3 As shown, the positioning component 3 is arranged on the inner side of the positioning frame 2, and the positioning component 3 includes a winding member 31, and the winding member 31 is arranged on the inner side of the positioning frame 2. A connecting member 32 is arranged on the inner side of the positioning frame 2, and a fixing member 33 is arranged on one side of the connecting member 32.

[0023] The winding member 31 includes a positioning rod 311 fixedly connected to the inner side of the positioning frame 2 , a winding drum 312 is arranged on the outer side of the positioning rod 311 , and a groove 313 is provided inside the positioning frame 2 .

[0024] The connecting member 32 includes a first connecting plate 321 and a second connecting plate 322 which are respectively fixedly connected to the inner side of the positioning frame 2 .

[0025] The fixing member 33 includes a fixing frame 331 welded to one side of the first connecting plate 321 , and a threaded rod 332 is fixedly connected to the inner side of the fixing frame 331 .

[0026] The threaded rod 332 includes a nut 5 threadedly connected to the outer side, and a support block 6 is slidably connected to the outer side of the threaded rod 332.

[0027] The winding drum 312 is supported by the positioning frame 2 and the positioning rod 311, which facilitates the winding drum 312 to wind up the wire rope. The two fixing frames 331 are respectively welded to one side of the first connecting plate 321 and the second connecting plate 322, which play a supporting and fixing role. The threaded rod 332 is fixed on the inner side of the fixing frame 331. Two nuts 5 are arranged on the threaded rod 332 and placed on both sides of the support block 6. The support block 6 slides on the outer side of the threaded rod 332, which is convenient for adjusting the position as needed. When the two nuts 5 are rotated respectively, under the action of the nuts 5, it is convenient to clamp the support block 6, which is beneficial to limit and fix the support block 6 and enhance the stability at the same time.

[0028] refer to Figure 1 , Figure 3 and Figure 4 As shown, the anti-wear component 4 is arranged on the inner side of the positioning frame 2.

[0029] The anti-wear assembly 4 includes a limiting member 41 disposed on one side of the supporting block 6 , and a control member 42 is disposed inside the limiting member 41 .

[0030] The limiting member 41 includes a limiting cylinder 411 fixedly connected to one side of the supporting block 6 , a first limiting block 412 is fixedly connected inside the limiting cylinder 411 , and a fixing plate 413 is arranged on the top of the first limiting block 412 .

[0031] The control member 42 includes a second limit block 421 threadedly connected to the inner side of the limit cylinder 411, a handle 422 is fixedly connected to one side of the second limit block 421, a support rod 7 is provided on one side of the second limit block 421, and a roller 8 is rotatably connected to the outer side of the support rod 7.

[0032] One side of the two support blocks 6 is respectively fixedly connected with two limit cylinders 411, and the two ends of the support rod 7 with the roller 8 are respectively inserted between the two sets of first limit blocks 412 and second limit blocks 421. Under the action of the handle 422, the second limit block 421 is rotated so that the second limit block 421 moves toward the direction of the first limit block 412, and the distance between the first limit block 412 and the second limit block 421 is shortened, so that the first limit block 412 and the second limit block 421 clamp the support rod 7, and the support rod 7 is preliminarily positioned. The first limit block 412 and the second limit block 421 are fixed by the fixing plate 413 and bolts, which effectively prevents the second limit block 421 from moving uncontrollably, enhances stability, and further improves the fixing effect of the support rod 7. At the same time, it is convenient to disassemble and replace the roller 8. During the operation of the wire rope, the wire rope and the roller 8 are in rolling contact, which avoids damage caused by direct contact and friction between the wire rope and the steel structure. To a certain extent, it plays a role in protecting the wire rope from wear, ensuring safety and stability during operation, and is conducive to extending the service life of the wire rope.

[0033] Working principle: When in use, the two fixing frames 331 are welded to one side of the first connecting plate 321 and the second connecting plate 322 respectively, and the fixing frame 331 is fixed. The threaded rod 332 is fixed and supported by the fixing frame 331, and a running track is provided for the position adjustment of the support block 6. The support block 6 slides on the outside of the threaded rod 332 to facilitate the adjustment of the position. The limiting cylinder 411 is supported and fixed by the support block 6, and the two ends of the support rod 7 with the roller 8 are respectively inserted between the first limiting block 412 and the second limiting block 421. The second limiting block 421 is rotated by the handle 422 so that the second limiting block 421 moves toward the first limiting block 412. The support rod 7 is preliminarily clamped and fixed by the first limiting block 412 and the second limiting block 421. Under the use, the first limit block 412 and the second limit block 421 are fixed to prevent the second limit block 421 from loosening, thereby enhancing the stabilizing effect of the support rod 7, and the support block 6 drives the roller 8 to slide under the limit of the threaded rod 332, so as to facilitate the adjustment of the position of the roller 8 as needed. After the adjustment is completed, the nuts 5 on both sides of the support block 6 are rotated respectively to limit and fix the support block 6, and then the position of the roller 8 between the first connecting plate 321 and the second connecting plate 322 is fixed. A plurality of groups of rollers 8 can be arranged between the first connecting plate 321 and the second connecting plate 322 as needed. When the wire rope is running, the wire rope and the roller 8 are in rolling contact, so as to avoid direct contact and friction between the wire rope and the steel structure, effectively reduce the wear of the wire rope, ensure the stability of equipment operation, extend the service life, and save maintenance and replacement costs.
