DETAILED DESCRIPTION

[0025] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figures 1 to 5 :

[0027] A lifting wire cutting machine includes a frame 1 and a cutting device 2 arranged on the frame 1 and used to cut stone 9, a lifting device 3 for lifting the stone 9, and a transport device for transportation. The frame 1 includes a base 11 and four upright columns 12 distributed upright at the four corners of the base 11. An accommodating space 13 for receiving the stone 9 is formed between the base 11 and the four upright columns 12.

[0028] The lifting device 3 includes a supporting mechanism 31 disposed within the accommodating space 13 and a lifting mechanism 32 for moving the supporting mechanism 31 up and down. The supporting mechanism 31, through the lifting mechanism 32, drives the stone 9 to move up and down within the accommodating space 13 and feeds the stone 9 to the cutting device 2 for cutting. Preferably, the base 11 can be made of reinforced concrete material on site. When making the reinforced concrete base 11, a number of dry anchor bolts can be pre-embedded in the base 11.

[0029] The lifting mechanism 32 includes a screw rod 321 mounted on each column 12 and a motor 322 for driving the corresponding screw rod 321. Specifically, the output shaft of the motor 322 is connected to a first gear 324. Each screw rod 321 is fitted with a screw nut 323 threadedly connected to the screw rod 321. The outer surface of the screw nut 323 is fixedly fitted with a second gear 325 meshing with the first gear 324. The motor 322 drives the first gear 324 to rotate, which in turn drives the second gear 325 mounted on the outer surface of the screw nut 323 to rotate together, causing the screw nut 323 to rotate and drive the screw rod threadedly engaged with it to move up and down along the length of the column 12. Preferably, the diameter of the first gear 324 is smaller than the diameter of the second gear 325.

[0030] Furthermore, each column 12 is provided with a through hole in the vertical direction for the screw rod 321 to pass through, and a hollow extension column 326 is extended upward from the upper end of the through hole. The extension column 326 is connected to the through hole, and the screw rod 321 is movably arranged in the through hole and the extension column 326 along the up and down directions.

[0031] Furthermore, bearings 327 are provided at both upper and lower ends of the first gear 324 and upper and lower ends of the second gear 325 .

[0032] Furthermore, a connecting rod 328 is fixedly connected to the bottom of the screw rod 321, and the supporting mechanism 31 includes a supporting plate 311, a connecting plate 312 arranged around the supporting plate 311 and extending outward and connected to the connecting rod 328, and a limiting unit to prevent the supporting plate 311 from shaking during movement. The limiting unit includes a slide rail 121 disposed on each column 12 on a side opposite the accommodating space 13, and a limiting member 313 disposed on the supporting plate 311 and movably abutting against the slide rail 121. The limiting member 313 includes a fixing member 3131 fixed to the supporting plate 311, a movable rod 3132 retractably disposed within the fixing member 3131, a movable member disposed at an end of the movable rod 3132 away from the fixing member 3131, and a spring 3133 disposed between the movable member and the fixing member 3131 and sleeved on the outside of the movable rod 3132. The end of the movable member closest to the corresponding slide rail 121 is provided with a slide groove 3134 that is compatible with the slide rail 121. The provision of the spring 3133 can provide a buffer when the stone 9 shakes, reducing the shaking of the stone 9 when it is raised or lowered.

[0033] Furthermore, the slide groove 3134 is one or more of a V-shaped groove or a parallel groove. The drive motor 322 drives the second gear 325 (first gear 324, screw nut 323) to rotate, thereby driving the screw 321 to move up and down within the through hole, that is, driving the support plate 311 to move smoothly up and down within the accommodating space. Moreover, the vertically arranged V-shaped groove or parallel groove can further stabilize the path of the support plate 311 during up and down movement, ensuring that it does not wobble during up and down movement, thereby allowing for planned cutting of the stone 9 disposed on the base 11. Preferably, in this embodiment, two V-shaped grooves and two flat grooves are used. The parallel grooves restrict the left and right shaking of the stone 9 disposed on the support plate 311, while the V-shaped grooves restrict the front and back shaking of the stone 9.

[0034] Furthermore, the base 11 is a cast concrete platform and a sunken space 111 for placing the supporting plate 311 is provided in the middle.

[0035] The transport device includes a first rail 41, a second rail 42 and a material cart 43. The first rail 41 is fixed on the base 11 and is arranged on both sides in front of the sunken space 111. The second rail 42 is arranged on the supporting plate 311. The second rail 42 is flush with the first rail 41 along the length direction. When the supporting plate 311 is arranged in the sunken space 111, the upper surface of the second rail 42 is flush with the upper surface of the first rail 41. Rollers 431 are provided at the bottom of the material cart 43 for transporting stone 9 on the second rail 42 and the first rail 41.

[0036] Furthermore, the cutting device 2 includes a cutting frame 21, guide wheels 22 horizontally arranged at the four corners of the cutting frame 21, guide wheel motors 23 mounted on the cutting frame 21 and corresponding to the guide wheels 22, and a winding unit and an unwinding unit (not shown) arranged on both sides of the frame 1. The output end of each guide wheel motor 23 is connected to the corresponding guide wheel 22. The guide wheel 22 is covered with a rubber surface layer and is made of aviation aluminum. The rubber surface layer is made of ultra-high molecular weight polyethylene. The use of the lightweight aviation aluminum guide wheel 22 reduces the lifting load of the cutting frame 21. The outer cover is provided with an ultra-high molecular weight polyethylene rubber surface layer, which improves the wear resistance of the guide wheel 22.

[0037] The outer surface of the rubber surface layer is provided with a plurality of winding grooves for the diamond yarn to pass through. The diamond yarn passes through the winding grooves of the four guide wheels 22 in sequence to form a plurality of parallel cutting lines.

[0038] The winding unit and the unwinding unit are two winding devices with the same structure, both of which include a winding motor, a winding wheel connected to the output shaft of the winding motor, a guide wheel group and a tension control wheel group. The diamond yarn is connected to the winding motor after being guided by the winding wheel, the guide wheel group and the tension control wheel group. The winding motor can reel in and unwind the yarn.

[0039] The tension control wheel assembly includes a swing motor, the power output of which is connected to a swing arm, which is connected to a balance wheel that matches the diamond yarn. By controlling the swing arm's swing, the balance wheel pulls and releases the diamond yarn to adjust the diamond yarn tension. It is worth noting that the cutting device 2, winding unit, and unwinding unit in this embodiment are all consistent with the corresponding devices in a wire cutting machine disclosed in Chinese Utility Model Patent No. CN222858452U and will not be described in detail here.

[0040] A spray system 5 is mounted on the frame 1. This system comprises a water tank (not shown) mounted on the frame 1 and a water trough 51 positioned above the cutting frame 21. The trough 51 is provided with a plurality of through-holes 511, each of which is connected to a spray pipe (not shown). A hose is connected between the water tank and the spray pipes to transport water from the water tank to the spray pipes. This spray system 5 can be used to remove dust from the stone cutting process and to cool the cutting device 2 from the heat generated during stone cutting.
