[0028] like Figures 1 to 4 As shown, this embodiment provides a rope saw cutting device, which includes a steel wire rope 1 on which a bead group is arranged.

[0029] The bead group includes a plurality of beads. During the wire saw cutting process, in a bead group, among adjacent beads, the cutting surface of the bead that is cut first is smaller than the cutting surface of the bead that is cut later.

[0030] In the present application, since the beads with small cutting surfaces are cut first and the beads with large cutting surfaces are cut later, the heat generated by the original cutting is dissipated separately in multiple times, which can increase the life of the beads, reduce heat generation during the cutting process, avoid large amounts of water cooling, and reduce water resource waste.

[0031] The diameters of the beads arranged on the steel wire rope 1 are equal. The bead set includes three beads, which are first-type beads 2, second-type beads 3 and third-type beads 4.

[0032] The cutting surface of the first type of beads 2 is smaller than the cutting surface of the second type of beads 3 , and the cutting surface of the second type of beads 3 is smaller than the cutting surface of the third type of beads 4 .

[0033] The first type of bead 2 is provided with a plurality of uniformly arranged cutting tips in the circumferential direction, and the angle between adjacent cutting tips is 15 to 40 degrees.

[0034] The second type of beads 3 are provided with a plurality of uniformly arranged cutting tips in the circumferential direction, and the angle between adjacent cutting tips is 40-75°.

[0035] The third type of beads 4 are round beads.

[0036] During operation, the first type of beads 2 has a smaller cutting area and generates less heat, while the second type of beads 3 has a slightly larger cutting area than the first type of beads 2. After the first type of beads 2 are cut, the second type of beads 3 are used for cutting, and the heat generation will not be too large. The third type of beads 4 cuts the position after the second type of beads 3 are cut, and the heat is not large. That is, the heat generated by the original cutting is divided into 3 parts and dissipated separately. The original water-cooled cutting saw can be changed to air-cooled, saving cooling water. When the beads are severely worn, the rope saw can be turned 90 degrees and the unworn position can be changed to continue cutting. After rotating 4 times, replace the new beads.

[0037] There are transition sections 5 at both ends of the beads, the diameter of which is smaller than that of the bead body, and the transition section 5 is connected to the steel wire rope 1 through a fastener.

[0038] The fastener is a positioning bolt. There is a small hole on the opposite side of the transition section 5 for passing the positioning bolt. The positioning bolt passes through the middle of the wire rope 1 to fix the bead position relative to the wire rope 1. A nut is provided on the opposite side of the positioning bolt.

[0039] Adjacent beads are spaced apart from each other, springs 7 are arranged between adjacent beads, and rubber 8 is arranged on the outer side of the spring 7 .

[0040] The driving wheel of the wire saw cutting device is gear 6, which drives the wire rope 1 to move. The driving wheel that drives the wire saw to rotate is also changed from the original perfect circle to gear 6, and the concave part of gear 6 avoids the bead position to prevent the beads from being worn at the driving wheel and the bead sharp corners from damaging the driving wheel.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
