For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Refer to the attached Figure 1-4 , a cable roller, comprising:

[0029] The clamping parts 1 are symmetrically arranged in two pieces; the clamping parts 1 are truncated cone-shaped, and a through hole is opened in the middle thereof; a bearing 2 is arranged in the through hole; a mounting groove 3 is opened at the inner ends of the two clamping parts 1;

[0030] The first rotating part is located between the two clamping parts 1, and includes a rotating cylinder 4 and a connecting cylinder 5; the inner ring of the rotating cylinder 4 is provided with a limit pin 6; the connecting cylinder 5 is located in the inner ring of the rotating cylinder 4, and is provided with a limit groove 7 corresponding to the position of the limit pin 6; the two ends of the connecting cylinder 5 are respectively located in the mounting grooves 3 at corresponding positions;

[0031] The second rotating part is located in the inner circle of the connecting cylinder 1 5, and includes a rotating cylinder 2 8 and a connecting cylinder 2 9; a limiting pin 2 10 is provided in the inner circle of the rotating cylinder 2 8; the connecting cylinder 2 9 is located in the inner circle of the rotating cylinder 2 8, and is provided with a limiting groove 2 11 corresponding to the position of the connecting pin 2; both ends of the connecting cylinder 2 9 are respectively located in the mounting grooves 3 at corresponding positions;

[0032] The wear portion 12 is sleeved on the outer ring of the first rotating portion, and its two sides are respectively fitted with the clamping portion 1 at corresponding positions; the outer ring of the wear portion 12 is in an arc-shaped concave shape, and the diameters of its two ends are larger than the diameter of its middle.

[0033] In this embodiment, a plurality of positioning holes 13 are provided at intervals at both ends of the connecting tube 1 5, and a plurality of positioning holes 2 14 are provided at intervals at both ends of the connecting tube 2 9; a plurality of screw holes and locking members 15 corresponding to the screw holes are provided at the outer end of the clamping portion 1; the locking member 15 includes a connecting plate 16 and a locking bolt 17; an avoidance hole 18 is provided at one end of the connecting plate 16, and two limiting columns 19 are provided at intervals at the other end; the two limiting columns 19 penetrate the clamping portion 1 and respectively enter the positioning hole 13 and the positioning hole 2 14 at corresponding positions; the locking bolt 17 passes through the avoidance hole 18 at corresponding positions and cooperates with the screw hole thread.

[0034] In addition, a positioning block 1 20 and a positioning block 2 21 are provided in the installation groove 3; the positioning block 1 20 is fitted with the inner wall of the installation groove 3 and corresponds to the position of the limiting groove 1 7; a gap is left between the positioning block 21 and the positioning block 1 20 and corresponds to the position of the limiting groove 2 11. The limiting ring 22 is located in the installation groove 3, clamped in the gap between the positioning block 1 20 and the positioning block 2 21, and corresponds to the position of the rotating drum 2 8.

[0035] During installation, the first rotating part and the second rotating part are assembled separately, and then the part of the limiting groove 11 of the connecting tube 9 of the second rotating part that exceeds the limiting pin 10 is aligned with the positioning block 21 in the mounting groove 3 at the inner end of the clamping part 1; at this time, the positioning holes 14 opened at both ends of the connecting tube 9 are respectively aligned with the holes opened on the clamping part 1, so as to facilitate the locking with the first rotating part through the locking member 15 later. It should be noted that before installing the second rotating part, the limiting ring 22 needs to be placed in the mounting groove 3 in advance to avoid rework later.

[0036] Similarly, after one end of the second rotating part is fixed to the clamping part 1, the first rotating part is sleeved on the outer ring of the second rotating part and slowly slid to the clamping part 1 close to one end. When the first rotating part is close to the clamping part 1, the part of the limiting groove 7 of the connecting tube 5 that exceeds the limiting pin 6 is aligned with the positioning block 20, and then the connecting tube 5 and the connecting tube 2 9 are locked together on the clamping part 1 through the locking member 15.

[0037] After the first rotating part and the second rotating part are fixed to the clamping part 1 at one end, the wear part 12 is sleeved on the outer ring of the first rotating part and slowly moved to the clamping part 1 close to one end; the end of the wear part 12 in contact with the clamping part 1 is completely fitted with the truncated cone slope of the clamping part 1. After the above steps are completed, the clamping part 1 at the other end is locked with the other end of the first rotating part and the second rotating part through the locking member 15 to complete the assembly of the roller.

[0038] It should be noted that the two limit posts 19 on the connecting plate 16 of the locking member 15 are made of high-strength steel or other materials, which can withstand the pressure during the rotation of the roller without deformation, and are easy to reuse. On the other hand, the rotating cylinder 14, the connecting cylinder 15, the rotating cylinder 28 and the connecting cylinder 29 are made of materials of different colors, which is convenient for judging the degree of wear of the roller. The limit pin 16 and the limit pin are of the same color and are different from the colors of the rotating cylinder 14, the connecting cylinder 15, the rotating cylinder 28 and the connecting cylinder, which is convenient for judging to which level the roller has been worn during the rotation of the roller. When replacement is needed, the severely worn parts can be replaced according to the degree of wear, and the unworn parts can be reused, which can save costs.

[0039] The cable roller of the utility model can not only conveniently judge the degree of wear of the roller, but also can reuse the unworn parts by replacing the worn part 12 and other worn parts, which is beneficial to saving resources, controlling costs and avoiding waste. It is very practical and has good market application prospects.
